Advancing the Responsible Use of Medicines in Belgium
IMS Health Report Advancing the Responsible Use of Medicines in Belgium Applying Levers for Change Executive Summary Pharmaceutical innovation is an obvious and important contributor to the health of a society, but in times of economic constraint, payers often have difficulty taking full advantage of it. According to an IMS Health analysis (data on file), Belgium has thus far been able to maintain the levels of spending on innovative drugs that it enjoyed prior to the economic crisis that began in 2008. The analysis covered spending per capita over the periods 2005 to 2009, and from 2010 to 2014. Indeed, over the past five years, Belgium has maintained its position as one of the four EU countries spending the most on innovative drugs per capita. Meanwhile countries where the economic crisis has had a major impact (such as Spain, Ireland, Greece, and even France) have slipped in the ranking. Yet, ensuring that Belgium continues to be able to offer innovation to its people will require the efforts of all stakeholders. Within the current economic climate, promoting responsible use of medicines should be a key priority for health policymakers. In this context, IMS Health calculated the potential for savings that could be realized from how drugs are used—savings that could then be reinvested in covering innovative drugs. A clear and simple methodology was used to analyse the potential for cost savings in four areas: •• ➢Low adherence to statins therapy •• ➢Inappropriate and over-prescribing of antidepressants •• ➢Over-prescribing of antibiotics •• ➢Hospitalizations due to medication errors Note that the analysis was limited to these four topics because the methodology was simple and straightforward; this is by no means an exhaustive list of the areas where savings might be achieved. This report should serve to open a dialogue on the subject and to spur other stakeholders to investigate additional potential sources of potential savings. Overall, the study revealed that potential savings could reach an estimated 1.5 - 1.6% of Belgium’s total annual healthcare spending. In absolute values, this represents over €400Mn annually that could be invested in funding innovative treatments, broadening access restrictions to specific drugs, implementing prevention programs, and modernizing hospital infrastructures, etc. IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page i EXECUTIVE SUMMARY Low adherence to statins therapy It is generally accepted that drugs are less efficacious when patients do not adhere to the prescribed treatment regimen, leading to more medical complications and greater costs. For example, poor adherence to cardiovascular treatment has been shown to contribute to poor health outcomes with a faster onset of co-morbid conditions. This, in turn, increases the economic burden of disease since other medical resources are consumed at higher rates (e.g. hospitalizations for acute events) (Sokol, 2005; McDonnell, 2002; Senst, 2001). We estimated that €126Mn to €151Mn in annual hospitalization costs could be avoided in Belgium simply by increasing compliance levels to 90% in the statins market. The cost of treatment with statins would increase an estimated €68Mn a year, so the real savings are between €57Mn and €82Mn. This point is illustrated with statins, but a similar case could be made for improving adherence to antihypertensives as well as all other chronic treatments. Inappropriate and over-prescribing of antidepressants Western societies tend to have common issues around properly diagnosing and treating mental illness. While the use of antidepressive medication is increasing worldwide, it is particularly high in Belgium, where suicide rates are among the highest compared to the other European countries. Yet, the country’s utilization rates of antidepressants may reflect a combination of underuse, miss-use, and even over-use. By comparing Belgium’s prescription patterns to those of neighbouring countries, France and the Netherlands, we estimated that the potential avoidable cost from antidepressant miss-use/over-use is approximately €67Mn to €70Mn annually. Given this insight, national policies should be focused on the quality of prescribing in depression, on controlling the inappropriate use of antidepressants, and on providing alternative solutions to drug therapies. As an example, occupational therapy and physical activities could be integrated into nursing homes and community service centres to promote the wellbeing and mental health of elderly individuals. Additionally, psychotherapy performed by psychologists could also be reimbursed to support the improvement of mental health indicators. Over-prescribing of antibiotics The misuse of, and resulting resistance to, antibiotics has been identified as a major, worldwide public health concern. In Belgium, where several national programs have been launched since 2000, outpatient antibiotic use has decreased by 36% in terms of the number of packages sold. However, Belgians still consume many more antibiotics as outpatients than do their counterparts in other EU countries. We calculated that each individual in Belgium takes, on average, 12.66 antibiotic pills per year, which is twice the amount in the Netherlands. Our research showed that were prescribing behavior in Belgium to mirror that in the Netherlands, the country’s drug bill would be reduced by more than €70Mn a year. This estimate does not take into account the additional health and cost consequences of antibiotics resistance related to the overuse of antibiotics. Hospitalizations due to medication errors Medication errors are a preventable event that may lead to patient harm, and consequently, to costs. We estimated that based on Dutch sources, medication errors in Belgium could have been the cause of over 42,000 hospital admissions each year. The projected economic annual burden of avoidable medication errors was more than €200Mn. Measures to avoid medication errors are needed, however, it should be acknowledged that not all errors can be avoided.

Belgium Page v Introduction Context In 2012, the IMS Institute for Healthcare Informatics published a global report entitled “Advancing the responsible use of medicines - Applying levers for change.” It had been prepared for the Ministers’ Summit organized by the Dutch Ministry of Health, Welfare, and Sport held on October 3, 2012. The Summit, which was themed: “The benefits of responsible use of medicines: setting policies for better and cost-effective healthcare,” was part of a wider policy engagement agenda driven by the Dutch Ministry of Health that had been initiated in 2004 during the Dutch Presidency of the Council of the European Union. Also, the World Health Organization (WHO) commissioned a second report from the IMS Institute as an update to the WHO publication, “Priority Medicines for Europe and the World - A Public Health Approach to Innovation.” The WHO report was focused on key priorities for public health as identified in the organization’s 2004 report and updated to incorporate the latest advances in diagnostic technologies and treatments available. Some of the key, global public health issues identified in this report were the high burden of an aging population, coupled with the substantial health and cost burden of chronic, non-communicable diseases1 as well as the alarming rates of increased antibacterial resistance, tobacco use, alcohol abuse and obesity. The IMS Institute report, on the other hand, aimed to identify key healthcare spending areas where substantial cost savings could be achieved through better, more responsible use of medicines. Six areas were proposed as primary levers for change: •• Non-adherence to medicines •• Suboptimal generic use •• Medication errors •• Antibiotic misuse/overuse •• Mismanaged polypharmacy •• Untimely medicine use The study found that by optimizing the use of medicines, about 8% of the total (Global) healthcare spend, or about USD $500Bn could be avoided annually and re-directed to other sectors of healthcare. Using a similar methodology, The IMS Institute produced a follow-up report in June 2013 on the “Avoidable Costs in U.S. Healthcare.” The quantified missed opportunity costs in the U.S. were estimated at USD $200Bn annually. Analysts in IMS Health France have also studied non-adherence in six chronic diseases, estimating that about €9Bn could be saved in France by improving adherence.2 1These include: ischaemic heart and ischaemic cerebro-vascular disease, depression, osteoarthritis, Alzheimer disease, hearing loss, low back pain, chronic obstructive pulmonary disease (COPD) and alcoholic liver disease (mostly in Europe). 2http://www.imshealth.com/portal/site/imshealth/menuitem.c76283e8bf81e98f53c753c71ad8c22a/?vgnextoid=5150d58bed2a9410VgnVCM100000 76192ca2RCRD&vgnextchannel=5ec1e590cb4dc310VgnVCM100000a48d2ca2RCRD&vgnextfmt=default IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 1 INTRODUCTION Pharmaceutical innovation is an obvious and important contributor to the health of a society, but in times of economic constraint, payers often have difficulty taking full advantage of it. According to an IMS Health analysis (data on file), Belgium has thus far been able to maintain the levels of spending on innovative drugs that it enjoyed prior to the economic crisis that began in 2008. The analysis covered spending per capita over the periods 2005 to 2009, and from 2010 to 2014. Over the past five years, Belgium has maintained its position as one of the four EU countries spending the most on innovative drugs per capita. Meanwhile, countries where the economic crisis had a major impact (such as Spain, Ireland, Greece, and even France) have slipped in the ranking. Ensuring that Belgium continues to be able to offer innovation to its people will require the efforts of all stakeholders. With the present study, we aimed to give some robust, yet simple examples how substantial funds can be freed for other healthcare interventions and to initiate a debate in the public health arena, engaging policy makers, payers, prescribers, and patients together. We built upon the methodology and findings of the above mentioned studies, focusing our analyses on avoidable costs through the appropriate use of medicines in the Belgian healthcare arena. “Appropriate use of medicines” was defined as the cost-conscious and cost-effective prescribing of medicines through: •• ➢Improving adherence to drugs •• ➢Adequate prescribing of antidepressants and antibiotics •• ➢Avoidance of medication errors We tackled the appropriate use of medicines from a patient perspective (for example the non-adherence on cholesterol-lowering drugs, specifically statins) as well as from a public payer (government) perspective, recognizing that savings can have an impact on both. This focus was one limitation of our study in that we did not factor in some potentially important external cost elements, such as work productivity gains, savings from informal care, or gains in other industry areas. Nonetheless, the findings point to some important public costs that could be saved through immediate, easily-implementable programs aimed at improving medication prescribing and use. This does not mean, however, that there are no other areas where savings can be found. We encourage other stakeholders to investigate other areas where there may be similar or even greater savings that can be re-directed to pay for innovation. For each chapter of the report—one for each of the four areas of study—we present the background, methodology, and research findings where a great potential for cost savings was identified Conclusions and suggested means by which the policy and behavioural issues might be addressed are outlined at the end of each chapter. IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 2 Report 2.1 Low adherence to statins therapy 2.1.1Background “Drugs don’t work in patients who don’t take them” (Koop, 2009). Medication adherence has been clearly described by Vrijens et al (2012), as the process by which patients take their medication as prescribed. The process is composed of “initiation,” “implementation,” and “discontinuation.” Initiation occurs when the patient takes the first dose of a prescribed medication; discontinuation occurs when the patient stops taking the prescribed medication, and implementation is the extent to which a patient’s actual dosing corresponds to the prescribed dose regimen, from initiation until the last dose. Persistence is the length of time between initiation and the last dose, which precedes discontinuation. Medication non-adherence, mostly in chronic treatment, is of increasing concern to clinicians as it is now well established that non-adherence to medication contributes to poorer or even adverse health outcomes, both in the short and long term (e.g., faster progression to co-morbid conditions, contribution to increased risk of mortality). Further, the issue is now of growing concern among other healthcare stakeholders, such as payers and policymakers, due to the increasing evidence that non-adherence can result in higher costs of care, seldom offsetting the “savings” from not taking the respective medication. In Europe, cardiovascular disease has been ranked as the first contributor to the total burden of disease (measured in disability-adjusted life years) by the WHO, accounting for 21.4% of the total disease burden3 in 2012 (WHO, 2012). In the same report, having high cholesterol and being overweight (or obese) were listed among the five main modifiable risk factors to the total burden of disease in Europe, together with tobacco use, alcohol consumption, and high blood pressure. Clinical guidelines have repeatedly reinforced the need for adequate management of risk factors as contributors to major adverse outcomes of cardiovascular disease in patients who are at risk4. The evidence that reducing plasma LDL cholesterol reduces the risk of cardiovascular disease is unequivocal (Reiner et al, 2011; Baigent et al, 2010). Despite this, adequate control of physiological risk factors is still far below the recommended targets in many countries. The EUROASPIRE (European Action on Secondary and Primary Prevention by Intervention to Reduce Events) has shown that the integration of cardiovascular disease prevention into daily clinical practice is still highly inadequate in Europe (EUROASPIRE, 1997; EUROASPIRE II, 2001; Kotseva et al, 2009). In Belgium, 15% of the adult population with established coronary heart disease currently smokes, 80.3% are overweight, 25.5% are obese, 51.5% have elevated blood pressure, respectively 44.5% and 22.5% have elevated total and decreased HDL cholesterol, 22.5% have elevated triglycerides levels, and 29.6% have co-morbid diabetes. Only 55% of these patients achieve the indicated target for cholesterol control (serum total cholesterol < 4.5 mmol/l), despite the fact that over 80% are being 3Total burden of disease is expressed as disability-adjusted life years (DALYs); DALYs is a time-based measure that combines years of life lost due to premature mortality (YLLs) and years of life lost due to time lived in states of less than full health, or years of healthy life lost due to disability (YLDs); cardio-vascular disease burden is the summary of ischaemic heart disease and stroke. 4e.g. high-risk individuals: hypertensive, with established cardiovascular disease, with type 2 diabetes, with occlusive arterial disease of the lower limbs and carotid artery disease IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 3 Low adherence to statins therapy treated with lipid-lowering drugs (Kotseva et al, 2009). Poor medication adherence may explain the gap between treatment levels and adequate control of risk factors. Poor adherence to cardiovascular therapy is increasingly demonstrated to contribute to poor health outcomes. A recent meta-analysis of adverse cardiovascular events and mortality showed that individuals with sub-optimal level of compliance to statin therapy (defined as compliance level <80%) have a +15% higher risk5 of cardiovascular events (any fatal or non-fatal coronary heart disease, stroke or sudden cardiac death) and a +45% higher risk6 of all-cause mortality (Chowdhury, 2013). An analysis of data from the Reduction of Atherothrombosis for Continued Health (REACH) Registry, one of the largest contemporary outpatient worldwide registries, provides further evidence of the impact of non-adherence. Patients who were non-adherent with any evidence-based secondary prevention medication at study entry (medications studied were antiplatelets, lipid-lowering drugs, or antihypertensive agents) demonstrated an 18% higher hazard of the primary outcome of cardiovascular death/myocardial infarction/stroke at four years compared with patients who were adherent (17.4% vs. 13.4%; HR, 1.18; 95% CI, 1.11-1.25) (Kumbhani et al, 2013). A few studies have illustrated the possible economic implications of medication non-adherence in various disease areas (Sokol, 2005; McDonnell, 2002; Senst, 2001). Sokol et al (2005) found that for the different studied chronic medical conditions (diabetes, hypertension, hypercholesterolemia, and congestive heart failure), hospitalization rates were significantly lower for patients with high medication adherence. The higher medication costs were more than offset by medical cost reductions. Clearly, important savings can be obtained in these conditions when medication adherence is improved. In our analysis, we aimed to quantify the potential economic implications for Belgium of non-adherence to cholesterol-lowering drugs (statins) from a payer perspective. We opted to study statins because the dosing is normally one tablet per day, so it is possible to calculate adherence accurately. This is this is not always the case with oral antidiabetics and antihypertensive drugs where the daily dose prescribed can vary greatly between patients. 2.1.2 Methods: quantification approach In a study of 137,277 patients in the U.S., Sokol et al (2005) showed that patients who maintained an 80% to 100% medication adherence were significantly less likely to be hospitalized compared to patients with lower levels of adherence. The analysis was conducted across four medical conditions: diabetes, hypertension, hypercholesterolemia, and congestive heart failure. Hospitalization rates were reported for five levels of medication adherence, and the research explored the additional likelihood of being hospitalized in the respective year, should medication adherence be lower than 80-100%. For statins, the risk of hospitalization for the levels of adherence of 1-19% and 40-59% was assumed to be 15%, and for accuracy the 20-29% level was assumed to have the same risk. Hospitalization risk was 14% for the 60-79% level and 12% for the 80-100% level. To estimate the impact of non-adherence, we first determined adherence levels to statins therapy based on IMS Health LifeLink Treatment Dynamics (see explanation in annex). Specifically, we selected all patients in the IMS Health LifeLink Treatment Dynamics panel with a first or followup prescription for statins during the period January 2010-January 2013. From the time of first prescription and up to either December 2013 or loss of the patient from the panel, we counted the 5RR 95%CI for good vs. poor adherence 0.85, 0.81-0.89 6RR95%CI for good vs. poor adherence 0.55, 0.46-0.67 IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 4 Low adherence to statins therapy number of prescription re-fills and total days covered by prescriptions. Total days covered were determined as the number of days between two prescription fills in which the patient could be assumed to use at least one pill per day, based on the pack size of the last prescription. Dividing the total number of days covered by the number of follow-up days for each patient resulted in a %-adherence level. Next, we determined the number of avoidable hospitalizations corresponding to each adherence level as: •• The difference between the risk of hospitalizations in patients at 80-100% adherence and the risk of hospitalizations in patients with less than 80% adherence (reported Sokol, 2005); •• Multiplied by the number of Belgium patients in statins in each of the five adherence levels where a statistically significant risk difference was observed. To estimate the number of patients in each of the five adherence levels to the Belgium population, a multiplication factor was determined between the total number of patients in statins from the IMS Health LifeLink Treatment Dynamics (=310,601) and the total number of patients in statins in Belgium (=1,439,276) reported in Pharmanet report (INAMI, 2013). Finally, we estimated the total avoidable cost attributable to non-adherence by multiplying the number of avoidable hospitalizations due to non-adherence, by the average cost of a hospitalization in Belgium in 2014 (average cost over all APR-DRGs). We applied two costs. One was the real, average hospitalization cost for Belgium based on all Patients Refined Diagnosis Related groups (APR-DRGs €4,886). The other was the cost of hospitalizations related to cardiovascular disease—what could be considered as the hospitalizations to be avoided by adherence to statins (i.e., APR-DRGs codes 160-180, 190-207 - €5,865). Apart from this cost, we also included the extra treatment cost that results from increasing the adherence level to 80-100% from its initial level (we applied 90% adherence level as the average between 80 and 100%). For that, the annual number of tablets of statins consumed and the yearly treatment costs were estimated for all levels of adherence. It was assumed that each patient would receive one tablet per day. The cost of a tablet was estimated using data from IMS Health Belgian National Retail Database (see explanation in annex), by dividing the total annual expenditure for statins by the total number of tablets consumed in 2014 (on average 0.4€ per tablet). The additional cost due to increasing the adherence levels was defined as the cost difference between the current level of adherence and 80-100% adherence. Hence, the total amount that could be avoided by increasing the adherence is given as the difference between the total avoidable cost and the additional treatment cost required to raise the adherence levels. 2.1.3 Results: estimated avoidable costs The average duration of follow-up in the panel was 871 days. Sixty-five percent of the anonymized patients in the panel were below the acceptable 80% adherence level (Table 1). Linking adherence levels in our panel with the additional risk of hospitalizations as reported by Sokol et al (2005) (Figure 1), we estimated that 25,716 hospitalizations in Belgium across all causes were possibly attributable to the lack of optimal adherence to statins therapy. With the average cost per hospitalization in Belgium varying between €4,886 and €5,865, the total avoidable costs related to hospitalization would be between €126Mn and €151Mn (Table 1, Figure 2). However, to avoid this cost, if all patients were to raise their levels of adherence to 80-100%, treatment costs with statins would increase €68,475,301. Thus, the estimated total amount of savings would vary between €57Mn and €82Mn (Table 1). IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 5 Low adherence to statins therapy Note that in their study, Sokol et al (2005) considered annual risk of hospitalization across all causes. In turn, by quantifying only the additional risk versus an adherence level of 80100%, we attempted to disentangle the incidence of hospitalizations attributable to causes other than poor adherence. A potential caveat of our analysis stems from the limitations inherent in using a prescription database. Cases in which patients received a first prescription but who never purchased that medication within an appropriate period of time (considered primary non-adherence) are not captured.

Besides, the two situations might offset one another. Another limitation is that although we know the type and the strength of the statin used, we don’t know whether that was the appropriate type and strength for the patient. 2.1.4Conclusions Poor adherence to medication prevents the therapy from achieving its purpose, and exposes patients to the risk of adverse health events. In the case of lipid-lowering drugs, lack of adherence can result in cerebrovascular events, such as stroke, with possible associated lifetime disability; myocardial infarction; angina; and the possibility of developing heart failure, renal disease, peripheral vascular disease, and premature death. Consequently, these patients are at high risk of requiring acute and long-term care in hospitals and specialized centres, leading to an additional burden to the healthcare system. These analyses on statins serve as a clear example that can be extrapolated to other drugs and disease areas. However, each specific disease area should be evaluated individually, taking into account the defined daily dose. All relevant stakeholders—most particularly physicians and pharmacists—should commit to delivering education programs for patients aimed at increasing awareness of the risks associated with not adhering to medication as prescribed. 2.2 Inappropriate and over-prescribing of antidepressants 2.2.1Background Depression is recognized as a major public health issue worldwide, although primarily in developed countries. The “2012 Report on Global Burden of Diseases Study” published by the Institute for Health Metrics and Evaluation (IHME), showed that major depressive disorders accounted for 3.23% of disability-adjusted life years (DALY). This metric was introduced by the WHO to quantify the sum of the Years of Life Lost (YLL) due to premature mortality and the Years Lost due to Disability (YLD). Self-harm accounted for 2.7% of DALYs. The contributions of major depressive disorders (MDD) and IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 7 Inappropriate and over-prescribing of antidepressants self-harm to total DALYs in France, for example, were 4.11% and 2.68% respectively, and 7.1% and 1.46% respectively, in the Netherlands. The corresponding numbers for Belgium were 3.23% for MDD and 2.7% for self-harm. In economic terms, the Mental Health Economics European Network estimated that the percentage of the health budget devoted to mental health in 17 western European countries appeared to vary between 4 and 13% (Knapp et al. 2006b). In the European Union (EU), this accounts for 3–4% of the gross national product (GNP) (Gabriel and Liimatainen 2000). The most important contributor to direct costs of depression is hospitalization, accounting for around half of the total in the U.K. and three-quarters in the U.S. (Berto et al. 2000). The indirect costs (from unemployment, increases in absenteeism, and decreased productivity) attributable to mental disorders outweigh the direct treatment costs by two to six times in developed market economies (Greenberg et al. 1993; Kind and Sorensen 1993). In most countries, families bear a significant proportion of these economic costs because of the absence of publicly funded, comprehensive mental health service networks. As a result, governments and societies ultimately pay a price in terms of reduced national income and increased expenditure on social welfare programmes. Thus, the economic logic for societies and countries is simple: treating and preventing mental disorders is expensive, but leaving them unattended can be more so (Knapp et al. 2007). According to the WHO Regional Committee for Europe – 63rd session, about half of all mental disorders start before the age of 14. Cost-effective interventions exist, but less than 1% of mental health budgets are spent on prevention. Set against this background, the rates of antidepressant drug use have been increasing worldwide, backed by numerous activities aimed at raising awareness of the disease, the acceptance that it can be treated, the economic crisis, and patients’ and prescribers’ increasing confidence in the available treatments. From 2000 to 2012, the rate of antidepressant users more than doubled in EU countries, from 31 to 66 daily defined doses (DDD) per 1,000 individuals per day (OECD eLibrary, 2014). For Belgium, this rate increased from 39 to 70 per 1,000 individuals from 2000 to 2012 (OECD eLibrary, 2014). Still, in comparison with some neighbouring countries, figures are high in Belgium: in the Netherlands, the DDD for antidepressants increased from 30 to 42 per 1,000 individuals per day, and for France this rate increased from 41 to 50. According to the Itinera Institute, mental illnesses are the primary cause of invalidity in Belgium, 27% of long-term absenteeism is related to mental issues, and life expectancy of psychiatric patients is on average 15 years shorter. Each day, three individuals commit suicide and 20% of the population uses psycho-pharmaceutical drugs. Due to under-diagnosis or misdiagnosis, care is often provided too late, and only 25% receive appropriate care. Data from the RIZIV/INAMI (infospot – antidepressiva April/May/June 2014) show that the number of patients in Belgium having received reimbursement for an antidepressant increased from 1.02 million (1,027,287) in 2005 to 1.17 million in 2012 (1,169,208) and 1.18 million in 2013 (RIZIV/INAMI, Farmaceutische Kengetallen 2013). Antidepressants are also more frequently prescribed in older patient groups (Figure 3). The fact that antidepressants are more frequently prescribed in Belgium in older patient groups— and most frequently in residents of nursing homes—is confirmed by media coverage in recent years. (see also: http://www.ouderenhart.be/ARTS-VERPLEGING/MEDICATIE/medicatie.htm). Marc Justaert (Christian Sickness Fund) reported that more than 40% of residents in nursing homes are receiving antidepressants. On the other hand, under-diagnosis and under-treatment of depression in this IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 8 Inappropriate and over-prescribing of antidepressants Figure 3: Number of patients with reimbursement for antidepressants per age category Cost €m Dr. Els Licht (GP, epidemiologist, the Netherlands, 2008) reported that GPs miss the diagnosis of depression in two out of three elderly people. Under-diagnosis leads to under-treatment with increased risk for morbidity, suicide, decreased cognitive and social functioning, and early death (Fiske et al, 2009). This will, consequently, have an economic impact. 500K 11.0% 400K Number of Patients older age group is also a crucial problem. (http:// www.ouderenhart.be/PSYCHISCH_WELBEHAGEN/ DEPRESSIE_ZELFDODING/depressie-en-zelfdodingbij-ouderen.htm) 300K 23.7% 200K 17.1% 100K 2.8% According to official RIZIV/INAMI data, about 16.5% 0 22% of Belgian patients receiving 15-24 25-54 55-64 65-74 75+ antidepressants received only one package, Age Category (Years) and 11% received less than 30 daily doses on an Source: RIZIV/INAMI, infospot April/May/June 2014 annual basis (RIZIV/INAMI, Farmaceutische Kengetallen 2013). One explanation for this high percentage of short duration treatments might be intolerance to the drug, but it does raise a question about the treatment indications, as these drugs only start to have a therapeutic effect after two to three weeks. Additional data from the RIZIV/INAMI (RIZIV/INAMI, Farmaceutische Kengetallen 2013) show that in 2013, approximately 300 million daily defined doses (DDD’s) (292,282,176) of antidepressants were prescribed, meaning approximately 800,000 DDD’s per day. The most frequently prescribed were selective serotonin re-uptake inhibitors, followed by “other antidepressants.” Are the right medicines reaching the right patients? Most antidepressants in Europe are approved and recommended for treating moderately and severely depressed patients (NICE CG 28, 2005). Furthermore, there is general agreement in the medical literature that antidepressants are not effective in mild forms of depression and should not be used in these patients (Committee on Safety of Medicines’ Expert Working Group, 2003; NICE CG28, 2005). Yet, prescribing patterns show that about 67% of antidepressants prescribed in general practice in the U.K. are used in patients with mild depression, 30% in moderate depression, and 3% in severe depression (Martinez, 2005). Another study, from the U.S., showed that in 44% of cases, antidepressants were used for mild depression or other disorders (Elkin, 1995). The issue of inappropriate prescribing has been pointed out by Jureidini and colleagues who have argued that antidepressants are greatly misused, e.g., given in patient populations who do not benefit from them, or where the risks outweigh the benefits7, or given for an appropriate duration of time, in excessive doses. Conversely, the patients who most likely would benefit from these treatments remain under treated and under diagnosed (Jureidini, 2006). The level of antidepressant consumption depends on the prevalence of depression in a country, the prevalence of diagnosed depression, and the frequency of drug treatments within the context of other treatments, especially psychotherapy (Grandfils & Sermet, 2009). In Belgium, psychologists are 7 T hese populations include children, the elderly, mild depressive patients, and patients with indications where the effects of antidepressives have not been studied or have not been proven. IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 9 Inappropriate and over-prescribing of antidepressants not incorporated in the RIZIV/INAMI nomenclature, meaning that no reimbursement is granted for psychotherapy given by psychologists (http://users.myonline.be/allemeesch/KlinPsy/Terugbetaling.htm). Psychotherapy provided by psychiatrists is reimbursed in Belgium, although not all psychiatrists provide psychotherapy. Due to the fact that psychotherapy is, for the most part, not reimbursed in Belgium, Belgian GP’s currently do not have many alternatives to prescribing reimbursed antidepressants. Meanwhile, the Belgian recommendations for treating depression (Heyrman et al, 2008), center primarily on non-drug treatments, stating that antidepressants should be prescribed only for severe depression, along with referral to specialized psychotherapy. In France, psychotherapy from a psychiatrist is reimbursed, and under certain conditions, it is reimbursed if performed by a psychologist. (http://psychotherapie.comprendrechoisir.com/comprendre/remboursementconsultation-psychologue) In the Netherlands, healthcare insurers stopped reimbursing for almost all psychotherapists in 2013/2014 (http://www.europsyche.org/contents/14284/netherlands). This decision will most likely have an impact on the consumption of antidepressants, which will be observable in the coming years. In this analysis, we aimed to evaluate the current use of antidepressant medication in Belgium as compared to France and the Netherlands, and to evaluate whether current prescribing levels in Belgium correspond to patients’ needs. 2.2.2 Methods: quantification approach The first step in this analysis was to determine current spending levels for antidepressant and mood stabilizer prescriptions (ATC class N6A) in Belgium, the Netherlands, and France. Volume and value sales were determined in each country (i.e., the average number of pills sold per capita, and cost/pill respectively) based on IMS Health Belgian National Retail Database available to IMS Health in the three countries via the IMS MIDAS platform (2013 data). (See annex for further details.) We were able to estimate potential country-level prescription costs in Belgium by: 1. Multiplying the average number of pills/person in the Netherlands and in France, respectively, with the cost/pill in Belgium 2. Extrapolating the result to the total population in Belgium, assuming that prescribing levels in Belgium were equal to those in France or the Netherlands and using Belgian prices. The difference between the current spending and potential spending represented additional costs for antidepressants and mood stabilizers prescriptions in Belgium (vs. the Netherlands and France). In order to determine whether the additional costs were justified by better health outcomes or by savings in other healthcare resources, a number of epidemiological or resource-use outcomes related to depression were reviewed in the literature to date. In addition, we looked at medical diagnoses for which antidepressant prescriptions were used in Belgium. These were available from the IMS Health Medical Prescriptions database (see explanation in annex). In Belgium, the IMS Medical Prescriptions data are based on prescriptions written by a sample of 520 doctors (including GPs and psychiatrists) offering medical services in locations other than hospitals; this represents a coverage of 1.8% of the total number of practicing physicians in Belgium (data for 2014). Over the last decade, mental health policy recommendations from the WHO, (The European Mental Health Action Plan, 2013) have provided guidance supporting deinstitutionalization. This entails developing community-based mental health services and expanding the role of primary care and mental health staff to provide care and treatment in local settings. Accordingly, we performed an additional analysis using the IMS Health Longitudinal Patients database (IMS Health LPD, see annex IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 10 Inappropriate and over-prescribing of antidepressants for further details). In this database, information on diagnosis and prescriptions is available for a set of 360 GPs covering about 300,000 patients. Thus, we searched for the reason behind, and duration of, antidepressant prescriptions. 2.3.3 Results: estimated avoidable costs Based on the IMS Health Belgian National Retail Data (2013) (see annex for further details), Belgium’s per capital pill use of antidepressants was 45% and 48% higher than that of France and the Netherlands, respectively. If we compare these figures with the DDD per 1,000 individuals per day (OECD Library 2014) from 2012, the Belgian rate is 40% higher than in France (70 in Belgium versus 50 in France) and 66% higher than in the Netherlands (70 in Belgium versus 42 in the Netherlands). These figures confirm the fact that antidepressant use is higher in Belgium than in France and the Netherlands. This results in much higher spending on antidepressants in Belgium. With a 30% smaller population than the Netherlands, spending in Belgium is four times higher, and the per-person cost is six times higher. Table 2: Estimated anti-depressants prescription costs in Belgium, France and The Netherlands Pills/ Person Cost/ person €218,417,001 34.17 €19.61 1,551,696,977 €684,917,502 23.62 €10.42 388,295,877 €55,665,682 23.15 €3.32 Total population Total pills consumed Belgium 11,140,000 380,633,117 France 65,700,000 Netherlands 16,770,000 Total costs Source: IMS Health MIDAS; IMS Health Belgian National Retail Data Next, we estimated the additional spending on antidepressants that might exist in Belgium due to misuse and over prescribing. We compared the current “mental health status” of the Belgian population with that of neighbouring countries, France and the Netherlands. The estimated prescription cost difference, based on usage (pill/person) in Belgium vs. France and current cost/pill in Belgium was €67Mn, which represented 31% of current spending in Belgium.This is the estimated difference between the current total cost of antidepressant use in Belgium and the potential cost, at prescribing levels in France.

An examination of the indications for which antidepressants were prescribed, based on the IMS Health Medical Prescriptions Database, shows that in Belgium, most are for depression, but almost 4% of prescriptions are for sleep disturbance (Figure 5). Trazolan® is often prescribed in this case. The use of antidepressant medications for sleep problems is currently not supported by pharmacotherapeutic recommendations in Belgium (CBIP/BCFI, 2014). The proportion of antidepressants prescriptions for sleep disturbances in France and Netherlands was around 1%.

Using the IMS Health longitudinal patient database (see annex for further details), we performed an analysis of GPs’ antidepressant prescribing by diagnosis and duration of treatment. As explained before, antidepressant drugs are only effective in patients suffering from moderate to severe depression, and they are not indicated to treat sleeping and anxiety disorders. What is more, a treatment effect is only seen after three weeks. Thus, to assess whether antidepressants were accurately provided in primary care settings, prescribing data of antidepressants from 300 Belgian general practitioners were collected from the Longitudinal Patient Data (LPD) database. The chart above shows the percentage of patients IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 12 Inappropriate and over-prescribing of antidepressants Figure 6: Indications for antidepressant prescription and percentage being of short duration Euro (public Prices, 2013) % 1 pack of ≤30 units 59.9% Depression 15.9% 17.8% Sleep Disorders 30.3% Anxiety Disorder 7.5% 27.7% 13.6% All Patients 22.2% Source: IMS Health Longitudinal Patient Database receiving antidepressive drugs by the most important indication and treatment duration. We looked at patients treated in 2014 that had no prescription with antidepressants in 2013. The results presented in Figure 6 show that only 60% of patients receiving antidepressants are diagnosed with depression; the remaining patients have anxiety or sleeping disorders. Moreover, 16% of patients with depression received their medication for less than a month, which is insufficient according the mode of action of these drugs. Note that this percentage is a bit overestimated given that patients who received a prescription in November or December of 2014 might have received new prescriptions in 2015. Nonetheless, our findings are in line with the Farmaceutische kengetallen (2013) report stating that 11% of patients received only a 30-day supply. Further, a study on antidepressants use in Belgian nursing homes for the elderly showed that 34.2% (95 % CI 32.0, 36.4) of the residents were diagnosed with depression, and that 80.9% of these patients were treated with an antidepressant. Antidepressants were prescribed for depression in 66.2% of patients, for insomnia in 13.4% of patients, for anxiety 6.2%, and for neuropathic pain in 1.6% (Bourgeois, 2012). In the same context, 2010 statistics from the WHO’s Regional Office for Europe showed suicide rates and self-inflicted injuries to be much higher in Belgium compared to the Netherlands and France, with a rate of 16.85 suicides and self-inflicted injuries per 100,000 person-years. In France and in the Netherlands, the corresponding rates were 14.76/100,000 person-years and 8.84/100,000 personyears, respectively (WHO Regional Office for Europe, 2014). Depression Sleep Disorders Anxiety Disorder All Patients Belgium appears to have almost double the number of psychiatric beds/100,000 individuals vs. France (178.52 beds/100,000 in Belgium, 91.24 beds/100,000 in France) and 28% more than in the Netherlands (139.26 beds/100,000 in the Netherlands (WHO Regional Office for Europe, 2014). This evidence shows that while Belgium spends more on antidepressive medication, parameters of system performance (suicidal rates, resource use in other related areas) suggest that further mental health policy measures are needed. IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 13 Inappropriate and over-prescribing of antidepressants 2.2.4Conclusions Set against the increasing recognition of depression as a major public health issue, prescriptions of antidepressants have increased substantially over the past decade (Evans E. A et al 2014). Since 2000, the rate of antidepressants users more than doubled in the EU countries. In Belgium alone, the rate of antidepressants users soared from 39 to 70 per 1,000 individuals (OECD eLibrary, 2014). The medical community recognizes that antidepressants do not benefit all patients. However evidence from the literature shows that: •• Almost half of antidepressants are prescribed to patients in whom the risks do not outweigh the benefits, and •• Patients who could actually benefit from treatment may be underserved. There are, thus, high opportunity-costs associated with inadequate prescribing of antidepressants— costs that include the utilization of services to diagnose and treat individuals in real need, or the use of these resources elsewhere in the system. Misuse of antidepressants9 should be contained by quality prescribing protocols and regulated by strict recommendations in clinical care guidelines, or as part of the National depression program. Note that the largest percentage of antidepressant prescriptions are written for the correct indications (Figure 8, Figure 9), although a considerable percentage are not. Yet, even when they are prescribed for the right diagnosis, antidepressants are often misused (for too short a duration), as described above. Parameters of system performance (suicidal rates, resource use in other related areas) suggest that further mental health policy measures are needed, and that the money saved from reducing overuse could be re-invested in mental health prevention and in reimbursing for psychotherapy rather than in more pharmacological treatment. The value of psychotherapy in reducing the levels of depression and anxiety has been widely demonstrated (Dezetter A et al 2013). However, in Belgium, the practice is not reimbursed, except if performed by psychiatrists, only a limited number of whom are professionally trained in psychotherapy. Mental health indicators might be improved by promoting this type of therapy within the Belgium Health care system, such as has been done in the U.K. in a program, “Improving Access to Psychological Therapies” (http://www.iapt.nhs.uk/). Subsequent measures should focus on promoting the wellbeing of patients, considering the higher consumption of antidepressants within the elderly population and residents of nursing homes on one hand, and the under diagnosis and under treatment of depression on the other. As such, occupational therapy and physical activities should be introduced into patients’ daily lives, either in nursing homes or in community service locations. Patients could benefit from sessions of moderate-intensity activities (such as swimming, walking, and dancing); advice to exercise safely for 30 minutes for five or more days a week, using examples of everyday activities such as shopping, housework, and gardening; and participation in local walking schemes as a way of improving mental wellbeing and social activities (NICE, 2008). An educative program should be implemented and targeted to mental health professionals and GPs, providing instruction on the strict medical indications and guidelines for prescribing psychiatric drugs. Health authorities should understand that the limited time available for patient consultations—one of the pitfalls of the health system—may compromise physicians’ ability to accurately diagnose common mental health disorders. 8 Misuse in this context means prescribing to children and the elderly; for mild depression, sleep disorders, or other indications where safety and efficacy has not been studied or proven; or at inappropriate doses or for inadequate duration. IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 14 2.3 Over-prescribing of antibiotics 2.3.1Background Antibiotics resistance is the situation in which antibiotics lose their ability to kill or stop the growth of a specific bacterium. Antibiotics resistance may occur naturally as a result of mutations in a bacteria’s genes (acquired resistance). However, excessive and inappropriate use of antibiotics may accelerate the emergence and spread of antibiotic-resistant bacteria. Multi-drug resistant bacteria can cause a wide range of infections, such as urinary tract infections, pneumonia, diarrhea, skin infections, and bloodstream infections, etc. Patients in hospitals are at risk of infections unrelated to the reason for admission; hospital-acquired infections include bloodstream infections caused by Enterobacteriaceae, surgical-site infections caused by Staphylococcus aureus), or heart-valve infections caused by Enteroccocci resistant to vancomycin, and surgical-site and wound infections caused by Acinetobacter baumannii resistant to carbapenems. Excessive and inappropriate use of antibiotics represent the use of antibiotics against colds and flu caused by viruses, where antibiotics are not effective, or in cases when patients do not take antibiotics as prescribed (e.g., they shorten the duration of use, take lower doses or do not comply with the right frequency). In such situations, the bacteria may survive and develop resistance. The resistant bacteria may spread, and cause infections in other individuals (Belgian Antibiotic Policy Coordination Committee (BAPCOC), 2015). Antibiotics resistance has been identified as a major public health concern in the Priority Medicines for Europe and the World Project, commissioned by the Dutch Government in preparation of its presidency of the European Union (EU) in 2004. Antibiotics resistance was identified as a public health concern for the following reasons: •• The increasing resistance to antibiotics of gram-negative bacteria, such as escherichia coli and klebsiella pneumonia •• The low rate at which novel antibiotics are approved and registered for use in Europe and the U.S.; there have been no novel mechanism agents for Gram-negative organisms in decades •• The reduced possibility, if at all, to reverse acquired antibiotic resistance •• The growing evidence of the economic and social burden of antimicrobial resistance: increases in hospital stays, additional discharge costs to facilities, extra medical care needed, and productivity loss. The societal costs in the European Union, Norway and Iceland due to antimicrobial resistance in 2007 were estimated to be in excess of €1.5Bn per year (Norrby, 2006). Various activities have been initiated to create public awareness of this major public health threat. Examples include: •• The creation of the European Antibiotic Awareness Day (November 2010) •• The establishment of the European Antimicrobial Resistance Surveillance Network (EARS-Net), a network of national surveillance systems, coordinated and funded by the European Centre for Disease Prevention and Control, which provides reference data on antimicrobial resistance in Europe •• The establishment of the Epidemic Intelligence Information System (EPIS) module for Antimicrobial Resistance and Healthcare-associated Infections (ARHAI) in Warsaw 2011 IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 15 Over-prescribing of antibiotics Three major publications have been issued recently, providing a comprehensive overview of the threat posed by antimicrobial resistance in the U.S., Europe and worldwide: •• The U.S. Centers for Disease Control and Prevention (CDC) report on antibiotic resistance threats (2013) •• The “2013 Report Priority Medicines” for Europe and the World •• The World Health Organization “Antimicrobial resistance report: global report on surveillance 2014” In Belgium, several national programs have been launched since 2000 in order to increase the awareness of incorrect antibiotic use and problems of bacterial resistance. Since then, outpatient antibiotic use (based on the number of packages) decreased by 36%. Despite this reduction, outpatient use of antibiotics is still high in Belgium compared to other European countries. And, the use has not declined since 2006-2007. Meanwhile, between 2007 and 2013, the use of antibiotics in hospitals increased by 5.6%. The 14th national program was recently launched by the Belgian Antibiotic Policy Coordination Committee (BAPCOP). Set against this background, our aim was to determine whether antibiotics are over-prescribed in Belgium, and if so, what the costs and health consequences of this are. As shown in a number of studies, the prevalence of antibiotics resistance is strongly related to consumption. We compared current consumption of antibiotics in Belgium (expressed in number of pills/person/year) with antibiotics consumption and spending in the Netherlands, as well as rates of antibiotics resistance reported for the two countries. The Netherlands was chosen for comparison because the climate in both countries is the same, and as such the number of viral and bacterial infections is comparable (as we will show). We also looked at the indications for which antibiotics are prescribed for outpatients in Belgium. 2.3.2 Methods: quantification approach The total antibiotics consumption (number of sold pills) was determined using IMS Health Belgian National Retail Data for the year 2013. The ATC classes selected were: J1, J3, J4, A7A, D6A, G1C, and S3A. The corresponding total spending was determined taking into account public prices. We divided the total number of pills sold by the total country population to determine the number of pills consumed per inhabitant. In order to eliminate the impact of differences in unit prices between countries, we calculated a cost per pill in Belgium by dividing the total public spending by the total number of pills consumed. Multiplying the price per pill in Belgium by the number of pills per person consumed in the Netherlands and the total Belgian population, we estimated the potential public spending under a lower use of antibiotics. The difference between current and estimated spending represented potential cost savings through more conscious prescribing and use of antibiotics. Based on the IMS Health LPD data collected from 360 GPs covering about 300,000 patients, we checked the diagnosis, in ICD-10 coding, for which antibiotics were prescribed.

In this report, the total antibiotics use for 2011 was listed (expressed in number of DDD per 1,000 inhabitants per day) for European countries and Kosovo as compared to 29 ESAC-Net (European Surveillance of Antimicrobial Consumption Network) countries. Results are shown in the Figure 8. The lowest antibiotics consumption was observed in the Netherlands.

The status of antibiotics resistance in both Belgium and the Netherlands was also evaluated using the most recent data on the prevalence of acquired bacterial resistance in Europe available from the “2013 Report Priority Medicines for Europe and the World.” The figures below illustrate prevalence of invasive bacterial isolates with acquired multidrug resistance. Rates (ranges, exact percentages were not available in the report) of antibiotic resistant pseudomonas aeruginosa and staphylococcus aureus are higher in Belgium (10-25%) compared to the Netherlands (1-5%), while the prevalence of resistant escherichia coli and klebsiella pneumonia were comparable (Figure 9).

Despite the high use of antibiotics outside of hospitals in Belgium, a high number of hospitalizations attributable to inflammations and infections were recorded (2011, data from RIZIV/INAMI, Technische Cell, https://tct.fgov.be/webetct/etct-web): •• 17,514 hospitalizations attributable to renal and urinary tract infections (APR-DRG 463) •• 6,523 hospitalizations attributable to inflammations and infections in the respiratory system (APR-DRG 137) •• 34,456 hospitalizations attributable to non-viral pneumonia (APR-DRG 139) IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 18 Over-prescribing of antibiotics Additional data show that the incidence of hospital-acquired bacterial infections within internal care units in Belgium was 1.4 per 1,000 patient days for primary bloodstream infections, and 17.9 per 1000 intubation days for ventilation-associated pneumonia (NSIH, 2012). The Great Influenza Survey (GIS) was implemented in several European countries to assess the influenza like illness (ILI) incidence level in the community. GIS is an internet-based monitoring system that collects data from individuals voluntarily participating in an internet survey. Participants are asked to complete an electronic symptom questionnaire weekly, documenting any symptoms experienced since their last visit. Figures from the influenza season 2013-2014 indicate that ILIincidence in both countries is comparable. One might postulate that antibiotics are still being prescribed in these patients to speed their cure, despite several media campaigns to discourage this. To analyze general practitioners’ prescription trends for antibiotics, we used data available from the IMS Health LPD. Figure 10 below shows the indications for which antibiotics were mainly used by GPs. Almost 50% of antibiotic use was in indications where antibiotics are most often not needed because the condition is of a viral nature. Figure 10: Indications for which antibiotics are prescribed in Belgium Other 17% Bronchitis 17% Tonsilitis Nasopharyngitis (common cold) Laryngitis and Tracheitis 6% 14% 6% Pharyngitis 8% Upper airway infections Sinusitis 12% 8% Cystitis 12% Source: IMS Health Longitudinal Patient Database Finally, looking at infection-related death rates, there were 22.9 deaths per 100,000 inhabitants in Belgium due to infectious and parasitic diseases (ICD10 A00-B99), compared to an average of 13.9/100,000 in the European Union, and a rate of 12.7/100,000 in the Netherlands (Eurostat data for 2010, Causes of Deaths by Region). The evidence reported above (higher antibiotics consumption in Belgium compared to the Netherlands; a high number of infection-related hospitalisations in Belgium; comparable ambulatory infections in Belgium & the Netherlands (ILI), and higher infection-related death rates in Belgium compared to the Netherlands) suggest that antibiotics are likely misused and over prescribed in Belgium. Based on the current antibiotics consumption in the Netherlands, potentially €71Mn (€71,478,576) in costs could be avoided annually in Belgium if antibiotics were to be prescribed more conscientiously. The additional health and cost implications of antibiotics resistance are not taken into account here, but could lead to additional savings. IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 19 Over-prescribing of antibiotics 2.3.4Conclusions The increasing resistance of gram-negative bacteria to antibiotics, coupled with low rates of novel antibiotics discovery and the reduced (or non-existent) possibility of reversing antibiotic-acquired resistance, has led the European Centre for Disease Prevention and Control to declare antibiotics resistance a major public health priority. The prevalence of antibiotics resistance is strongly related to higher consumption. Yet, antibiotics continue to be highly prescribed and used in Belgium—at more than double the rate in the Netherlands. This intensifies the rate of anti-microbial resistant isolates and, as a consequence, the possibly of contributing to higher infection-associated mortality. As such, immediate measures to increase patient and prescriber awareness that antibiotics don’t work in viral infections (and that rest and analgetics are sufficient) could decrease the use and prescribing of antibiotics. Furthermore, the risks of misusing antibiotics and the consequences of antibiotics resistance warrant programs at local and national levels. 2.4 Hospitalizations due to medical errors 2.4.1Background Medication errors are unintentional errors in how medicines are prescribed, dispensed, administered, or monitored while controlled by a healthcare professional, patient, or consumer. They are the most common, single preventable cause of adverse events in medical practice. As the problem is gaining increased awareness, local strategies have been implemented in healthcare centers, such as, for example, automating and computerizing medication-use processes. Several studies have been conducted in order to measure the burden of medication errors within and across countries, as well as the impact on patient safety and on hospital and societal costs. Most of them are single-centre studies and are limited in the information they offer with regard to patients’ follow-up and the description of risk factors. Other studies do not report the additional costs resulting from re-admissions or the treatments administered in these cases. According to the WHO, in 8% to 12% of hospitalizations in Europe, medical errors and healthcarerelated adverse events occur; 23% of European Union citizens claim to have been directly affected by medical errors; 18% claim to have experienced a serious medical error in a hospital, and 11% claim to have been prescribed the wrong medication. Fifty to 70% of harmful medication errors could be prevented through comprehensive and systematic patient safety approaches. Also, strategies to reduce the rate of adverse events could lead to the prevention of more than 750,000 harm-inflicting medical errors per year, leading in turn to over 3.2 million fewer hospitalization days, 260,000 fewer incidents of permanent disability, and 95,000 fewer deaths per year (WHO Regional Office for Europe, 2014). European health authorities have identified the need for reducing medications errors, and, as a result, new EU pharmacovigilance legislation was established in July 2012. Adverse drug reactions resulting from medication errors in the EU must now be reported to the EudraVigilance (the EU database of adverse drug reactions). The European Medicines Agency (EMA) is responsible for facilitating the reporting of adverse drug reactions due to medication errors. The agency is also responsible for facilitating coordination between medicine regulatory authorities in the Member States, national pharmacovigilance centers and national patient–safety authorities. IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 20 Hospitalizations due to medical errors The goal is to enable the mutual exchange of information on the adverse reactions due to medications errors and to coordinate effective reporting to EudraVigilance. As this policy is still very recent, figures on the incidence, risk factors, and follow-up treatments across the EU Member States are scarce. In the present analysis, we set out to estimate the avoidable costs that are due to medication errors that lead to avoidable hospitalizations in Belgium. 2.4.2 Methods: quantification approach Leendertse et al (2008) analysed data from a prospective multi-centre “Hospital Admissions Related to Medication (HARM) Study.” The study determined the frequency and patient outcomes of medication-related hospital admissions in the Netherlands. A case-control (matched on age and sex) was used to determine risk factors for potential preventable admissions. A total of 13,000 unplanned admissions in 21 hospitals in the Netherlands were assessed during 40 days. Medication-related hospitalizations were defined as hospitalizations due to adverse drug effects (i.e., harm due to adverse effects of medication use, as defined by the WHO) or due to medication errors (i.e., preventable medication-related hospitalizations). A medication error was defined as any error made in the process of prescribing, dispensing, or administering the medication. An estimated 5.6% of acute hospital admissions in the study were medication-related, and 46.5% of these were assessed as potentially preventable. The most common medication errors found were: lack of a clear indication for the medication, non-adherence to the medication regimen, inadequate monitoring, and drug-drug interactions. The most common reasons for hospitalization were gastrointestinal tract problems, cardiovascular symptoms, respiratory symptoms, and poor glycaemic control. In 70.2% of the cases, the patient recovered completely, but in 6.3% of cases, the patient died, and in 9.3% of cases the patient experienced a disability after discharge. We used the incidence of preventable acute hospital admissions due to medication errors from this study (assuming the same incidence for Belgium and the Netherlands; specific figures for Belgium were not found) and applied it to the total hospital admissions in Belgium in 2011 (data from the National Hospital Stay Statistics, Belgian Institute for Health and Disability Insurance (RIZIV/INAMI)). In this way, we determined the number of hospital admissions due to avoidable medication errors in Belgium. Next, we multiplied the estimated number of avoidable hospitalizations with the average cost of a hospital stay, to produce an estimate of the total avoidable costs attributable to medication errors. The average cost of a hospital stay in Belgium was determined as the weighted average of all APR-DRG-related stays and the cost per APR-DRG stay, including in-hospital pharmacy, procedure, laboratory measures, and other costs (data from 2011). Costs were inflated to 2014 values using the observed annual trend in cost per APR-DRG between 2001 and 2011 (Table 5). IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 21 Hospitalizations due to medical errors Table 5: Estimated avoidable costs due to medication errors in Belgium Indicators Figures Reference Number of hospital admissions in Belgium, 2011 1,643,518 RIZIV/INAMI 2011 Incidence of hospital admissions medication-related 5.6% Leendertse, 2008 % of hospital admissions estimated as potentially preventable 46.5% Leendertse, 2008 % hospital admissions attributable to medication errors 2.6%* calculated Total number of hospital admissions due to medication errors that could have been avoided 42,797 calculated Average cost of a hospital stay €4,886 RIZIV/INAMI 2011 Total hospital avoidable hospitalization costs due to medications errors €209 million calculated * 5.6% (medication-related hospital admissions) * 46.5% (potentially preventable admissions) 2.4.3 Results: estimated avoidable costs The average cost of a hospital stay in Belgium (2014) was estimated to be €4,886 (calculations and assumptions are explained in section 2.2.2 of this document). Based on an incidence of 2.6% of total hospital admissions attributable to medication errors, the estimated avoidable cost was around €200Mn per year. Figure 11 displays the most common reasons for avoidable hospital admissions required due to medication errors (Leendertse A. J. et al, 2008). Figure 11: Reasons for preventable hospital admissions 16% 14% 12% 10% 8% 6% 4% To bring this possible savings into perspective, 2% we investigated codes for hospitalizations due 0% to drug use. In Belgium, the APR-DRG code 812 GastroCirculatory Respiratory GastroEndocrine intestinal systems symptoms intestinal system represents hospitalizations due to intoxication bleeding symptoms caused by medication. In 2011, representing the Source: Leendertse A. J. et al, 2008 latest data available online, 12,167 patients were coded under this APR-DRG with a mean cost of €2,713. Thus, the total expenditure due to drug intoxication was estimated at more than €33Mn—a figure obviously much lower than the €200Mn reported above. It should be noted that not all cases of intoxication can be avoided, since this classification also includes deliberate intake of an overdose. Also, since the reason for hospital admission is not always straightforward, medication errors reported by hospitals will be under reported. IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 22 Hospitalizations due to medical errors A very common medication error leading to hospitalization is insulin overdosing which leads to hypoglycaemia (Smith et al 2005). While insulin overdosing is not always an error, it can be the result of difficulty in finding the right dosage or poor self-monitoring. Projecting data extracted from the IMS Health Hospital Disease database to Belgium there are about 11,000 hospitalizations for hypoglycemia with an average cost of €10,000. Note that hypoglycemia can be the cause of car crashes and fractures due to falls, which explains the high hospitalization costs. The total expenditure for hospitalizations due to hypoglycaemia is around €110Mn. Again, not all hospitalizations can be avoided by better patient education, but the examples shown above put in perspective the €200Mn that was estimated. 2.4.4Conclusions Preventable medication errors, occurring as a result of lack of clear indication for the medication, non-adherence to the medication regimen, inadequate monitoring, and drug-drug interactions, may be the source of 2.6% of annual hospital admissions (Leendertse, 2008). Given the enormous cost and health burden of preventable medication errors, a synergic approach is warranted nationally and across borders. This would entail communicating with and involving all the different stakeholders (medical doctors, pharmacists, hospitals, national and international pharmacovigilance organizations) in the provision and delivery of care. A synergic approach is also warranted through patient-focused activities aimed to educate patients on the importance of taking medication as prescribed (at the correct dose and time, for the prescribed indication), declaring multi-medication, and reporting adverse drug reactions. Introduction of healthcare policies to avoid medication errors is highly recommended. IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 23 General conclusions Belgium has, thus far, retained its place among the top four EU countries spending the most on innovative drugs per capita—a fact critically important to maintaining the health and welfare of the country’s population. However, a country’s ability to guarantee the best possible treatment for as many patients as possible is clearly tied to the economic climate; those EU countries hardest hit by the recent economic crisis have had to compromise when it comes to providing access to innovative therapy. The experience in these countries serves as a clarion call to Belgium, underscoring the need to trim avoidable costs, thereby preserving funding for innovation. Yet, before moneys can be freed to support innovative interventions, it must be clear which current costs can be avoided. In this study, we analysed four possible areas where cost-savings could be achieved to avoid jeopardizing patients’ health and to actually improve it. The four areas for potential cost savings were: medication non-adherence, misuse of antidepressants, misuse of antibiotics, and medication errors. We want to stress again that we chose these areas because of the robust, simple, and straightforward nature of the methodology available. Other areas can and should be identified and studied to maintain the current internationally accepted good care that is provided to Belgian inhabitants. In each area, we identified the potential cost savings that could be used to support better healthcare interventions and health policy measures that generate opportunities to invest in better public healthcare in Belgium. On the matter of medication non-adherence, cardiovascular disease related to non-adherence to statins was analysed. Observational, outcomes studies have shown that treatment goals are still much below the recommended levels. Fifty-five percent of individuals with established coronary heart disease in Belgium do not reach the recommended target cholesterol levels, despite a wide-spread use of lipid-lowering therapy in more than 80% of the population at risk (Kotseva et al, 2009). According to Chowdhury (2013), low adherence to lipid-lowering drugs was associated with a +15% higher risk of cardiovascular events and a +45% higher risk of all-cause mortality. This, in turn, contributes to an increased economic burden of the disease (as a consequence of higher rates of adverse events and co-morbid conditions) (Sokol, 2005; McDonnell, 2002; Senst, 2001). We estimated that from €57Mn to 82Mn in annual costs of hospitalizations in Belgium could be avoided simply by increasing compliance levels to 80-100% in the statins market. Note, there is tremendous potential for further cost savings in all the other chronic medical conditions and drug classes.As such, various stakeholders (INMAI, sickness funds, physicians, pharmacists, etc.) should be focusing on how to increase adherence to drugs in chronic diseases, applying programs that have shown to be cost-effective. High consumption of antidepressive medication and the under diagnosis of depression, most frequently in the elderly, leads to misuse of antidepressants in Belgium. About 17.4% of antidepressants in the country are prescribed for sleep disorders, against current national pharmaco-therapeutic guidelines. And,in at least 15% of patients, the treatment duration was too short (IMS Health LPDs, 2014 and CBIP/BCFI 2014). This study estimated a potential annual avoidable cost due to antidepressants misuse/overuse in Belgium of approximately €67Mn to €70Mn, based IMS Health Report: Advancing the Responsible Use of Medicines in Belgium Page 24 General conclusions on prescription patterns in France and the Netherlands. On the other hand, health indicators have shown that depression is not always diagnosed and that suicide rates are high. We outlined several possible directions that could be taken to reduce the inadequate use of antidepressants in Belgium. Antibiotics resistance has been identified as a major worldwide public health concern; numerous activities have been initiated to create public awareness at both international and European levels. High prevalence of multi-drug resistant pseudomonas aeruginosa, staphylococcus aureus, escherichia coli, and klebsiella pneumonia are noted in Belgium (10-25% of the specific bacterial isolates). The prevalence of antibiotics resistance is strongly related to higher consumption. This study estimated that on average an individual takes 12.66 antibiotic pills per year in Belgium—twice the amount in the Netherlands. Despite the high consumption of antibiotics in Belgium, in 2011, over 58 thousand hospitalizations in the country were due to urinary tract infections, respiratory infections, or pneumonia. This study estimated a potential for more than €71Mn in savings in annual treatment costs, through more conscious prescribing of antibiotics. This estimate did not take into account the additional health and cost consequences of antibiotics resistance. Several programs to reduce the use of antibiotics in Belgium have met with some success, but it is clear that more has to be done to reach patients and physicians. Eight to twelve percent of hospitalizations in the European Union may be attributable to medication errors and healthcare-related adverse events (WHO, 2014). Of these, 50-70% could be prevented through comprehensive, systematic patient safety approaches. Various measures have been implemented recently to increase vigilance across the Member States. This study estimated that in Belgium, medication errors may have been the cause of over 42,000 hospital admissions each year. The projected annual economic burden of avoidable medication errors was more than €209Mn per year. Medication errors was the only area in which we tallied the totality of avoidable costs; in the other subject areas, we focused on single or specific therapeutic areas. Based on the four scenarios explored here, over €405 million could be saved annually, representing 1.5-1.6% of the total public health expenditure. (Note that there may be some overlap between the four areas and that the effects of one might impact the other.) This budget could be invested in other areas of healthcare, such as: funding innovative treatments, broadening access restrictions to specific drugs, implementing prevention programs, and modernizing hospital infrastructures, etc. It could also be valuable to re-invest the freed funds into efforts to organize primary care and provide in-home aid to patients. A number of key policy measures have been suggested (see the specific chapters), with immediate application and relatively low implementation costs.
