Report Page xiii Preface This examination of non-fatal drug related events attended by ambulance in Victoria is a collaborative project between Turning Point’s Population Health Research Program and Ambulance Victoria, and is funded by the Victorian Department of Health. Turning Point strives to promote and maximise the health and wellbeing of individuals and communities living with and affected by alcohol and other drug-related harms. Our work is essential to understanding the complexities of alcohol and drug use in our community and in developing effective approaches to prevent and treat dependence and other related harms. Turning Point was opened in 1994 and operates from a unique organisational model that combines excellence in research with best practice approaches to education and training, alongside clinical service delivery. This model means we operate from within the alcohol and other drug (AOD) sector while benefiting from specialist skills and knowledge across research, education, and service delivery disciplines. The organisation amalgamated with public health provider Eastern Health in October 2009 and is formally affiliated with Monash University. Turning Point is part of the International Network of Drug Treatment and Rehabilitation Resource Centres for The United Nations Office of Drugs and Crime (UNODC) and is a member of the International Harm Reduction Association. The organization is unique among alcohol and drug agencies for its mission to combine clinical services with research and training, and brings together a broad base of expert, experienced professionals in each of these three areas. The staff at Turning Point have specialist expertise in the design, implementation and monitoring of alcohol and drug related research and evaluation, and have experience in the development of practice standards and guidelines which have been packaged for use by a range of services. Turning Point has established a number of innovative programs and plays a key role in influencing government policy. A range of clinical services are provided by the organization including a state-wide 24-hour telephone assessment and referral service (DirectLine), withdrawal, opioid pharmacotherapy, and counselling treatment programs. Among its achievements, Turning Point has provided key input to advisory bodies such as the Premier’s Drug Advisory Council and the Premier’s Drug Prevention Council. Current research projects include the examination of the patterns of alcohol and other drug use and related harm in the Victorian community, and the development and evaluation of a number of treatment programs. The Turning Point Population Health Research Program is responsible for investigating patterns of alcohol and drug use and related harm using population-based datasets available in Victoria. The staff in the Population Health Research team currently include: Belinda Lloyd, Mohajer Abbass Hameed, Cass Connor, Annie Haines, Caroline Gao, Cathie Garrard, Cherie Heilbronn, Jessica Killian, Liliana Laskaris, Heather Laurie, Elizabeth Le, Daniel Leung, Sharon Matthews, Lisa Meyenn, Elke Mitchell, Rowan Ogeil, Melissa Reed, Andrew Rodsted, Adam Scott, Kay van Namen and Merran Waterfall. The Population Health Research team aims is to examine patterns of drug use and harm in Victoria and provide this information to policy makers, alcohol and drug workers, as well as other interested groups and individuals. Current projects include the Victorian Alcohol and Drug Statistics Series.

The rate of fatal heroin overdoses was increasing in Victoria in the late 1990s (Dietze, Fry, Rumbold, & Gerostamoulos, 2001), and in response to increasing concern about the prevalence of overdose, the current project was established to examine non-fatal heroin overdose in depth using ambulance service records (Dietze, Cvetkovski, Rumbold, & Miller, 1998). The project is funded by the Victorian Department of Health, formerly the Victorian Department of Human Services. Non-fatal versus fatal heroin overdose Surveys of people who inject drugs (PWID), along with anecdotal reports from users, suggest that the experience of overdose is common amongst heroin users both in Australia (e.g., Darke, Ross, & Hall, 1996a; Loxley, Carruthers, & Bevan, 1995) and overseas (e.g., Gossop, Griffiths, Powis, Williamson, & Strang, 1996). Darke et al. (1996a) found that 68% of respondents had experienced a heroin ’overdose’. A survey conducted in Victoria as part of the Illicit Drug Reporting System found that 64% of regular heroin users reported having an experience of at least one overdose (Jenkinson & Quinn, 2007). Indeed, heroin users identify overdose as the heroin related harm with which they are most concerned. Most research on heroin related overdose has examined fatal overdoses (Dietze et al., 2001; Farrell, Neeleman, Griffiths, & Strang, 1996). However, the examination of non-fatal heroin overdoses is likely to be far more informative than the examination of fatal heroin overdoses. This is because fatal overdoses represent only a small fraction of the total number of heroin overdoses; the majority of heroin overdoses remain non-fatal. Recognition of this fact has seen an increase in the research effort that has been directed at the examination of non-fatal overdoses (Darke et al., 1996a; Darke, Ross, & Hall, 1996b). This research has been important in terms of identifying risk factors for overdose and informing the development of strategies for the prevention of fatal overdose (Darke et al., 1996b; Farrell et al., 1996; Gossop et al., 1996). Ambulance service records Examination of non-fatal overdose has been conducted through surveys of PWID (e.g., Darke et al., 1996a). However, another potential source of information regarding these overdoses is records of ambulance attendance (Bammer, Ostini, & Sengoz, 1995; Degenhardt, Hall, & Adelstein, 2001; Dietze, Cvetkovski, Rumbold, & Miller, 2000; Dietze, Jolley, & Cvetkovski, 2003). The rate of ambulance attendance at heroin overdose has been found to be as high as 56% of total overdoses (Darke et al., 1996a). Recognition of this fact has seen an increase in the use of ambulance service records to examine the nature and prevalence of heroin overdose (Bammer et al., 1995; Degenhardt et al., 2001; Dietze et al., 2003). In this regard ambulance service records can provide rich information on heroin related overdose and have significant advantages over one-off surveys of PWID. For example, ambulance service records are not subject to the same sampling biases inherent in surveys of PWID (see Hser, 1993). Moreover, in contrast to one-off surveys, ambulance records are routinely collected and are thus sensitive to potential changes in heroin market characteristics such as changes in drug purity, policing practices and user behaviour. In Victoria, ambulance paramedics are required to complete an electronic patient care record (ePCR) for every incident that they attend and for which they provide a service. These electronic records are Ambo Project: Alcohol and Drug related Ambulance Attendances – 2012/13 Annual Report Page 6 downloaded onto VACIS, which contains the details of incident location and incident result (hospital journey etc.) along with additional details about the incident, such as the patient’s condition. This method of data collection superseded an earlier paper-based recording of incident and patient details (see previous periodic reports from this project). In early 1997 Turning Point commenced discussions with the Metropolitan Ambulance Service, now Ambulance Victoria, with a view to establishing whether their records could be used to examine non-fatal overdose in Melbourne. The resulting project was designed to examine non-fatal heroin overdose using ambulance service records through the establishment of a database of all ambulance attendances at overdose events in the Melbourne metropolitan area. With enhanced data collection available from June 1998, attendances involving drugs other than heroin can also be examined. The current report In this annual report, eighteen drug categories are examined: 1. Alcohol 2. Cannabis 3. Ecstasy 4. All amphetamine related attendances 5. Crystal methamphetamine 6. Other amphetamine 7. Benzodiazepines 8. Inhalants 9. All heroin related attendances 10. Heroin overdose (responding to naloxone) 11. Other heroin 12. GHB 13. Anticonvulsants 14. Antidepressants 15. Antipsychotics 16. Opioid analgesics 17. Other analgesics, and 18. Cocaine related attendances. The appendix includes key maps of the Victorian LGAs included in the report. Ambo Project: Alcohol and Drug related Ambulance Attendances – 2012/13 Annual Report Page 7 Chapter 2: Methods Data generated from VACIS® The results presented in this report are generated from an analysis of electronic data extracted from VACIS®. This system is used by Ambulance Victoria paramedics to record the details of all emergency cases they attend, the endpoint being an electronic patient care record (ePCR). The project team have developed a method for parsing the received VACIS® electronic data to correctly identify relevant alcohol and drug related cases and extract the required information. However, due to the structure of the data model in the VACIS® (point of care data collection), extracting alcohol- and drug-related attendance information requires additional programming, manual data entry and clerical validation so as to accurately extract the specific drugs or substances involved in the cases attended by ambulance. As a consequence, a separate database was developed for the current project that integrates and standardises information extracted from the VACIS® data supplied with the existing Turning Point project database. Victorian regional data became available from the system in 2011, hence the VACIS® data have now included both the metropolitan Melbourne area and the regional Victorian area. The current database contains information on: the drugs or substances involved geographic location type of location (e.g., indoors/outdoors, public building/private residence) time of day, day of week demographic details of patient (sex, approximate age) whether naloxone had been administered (yes/no) and response to naloxone administration (effective/not effective) outcome (e.g., taken to hospital/not transported) whether police co-attended other relevant clinical data (e.g., cyanisation, pupil size, respiratory rate). The database has in excess of 385,000 records that have been collected for the period of 01/06/1998 to 30/06/2013. Analysis of some of the data collected for this period forms the basis of this report. Data auditing and quality control The data are internally validated when parsed for import and conversion from the VACIS® transfer files provided by Ambulance Victoria to Turning Point. Variables and coding used in the VACIS® data are compared to the Turning Point database model and any discrepancies are flagged for investigation by project staff. When the VACIS® data have been parsed, converted and appended to the Turning Point database, the electronic PCR records are collated for review by project staff in order to manually code the various project-specific data required for reporting, including correctly coding the drugs and substances involved in the event. After the set of electronic PCR records is manually coded, the dataset is reviewed by senior project staff and extracted for cleaning prior to analysis. Multiple electronic PCRs for the same patient are aggregated and a random selection of cases is reviewed to ensure the manual coding was accurate Ambo Project: Alcohol and Drug related Ambulance Attendances – 2012/13 Annual Report Page 8 and consistent. Data are then converted to a format suitable for analysis and are merged with the Turning Point master project dataset. Preliminary analyses are performed to identify any anomalous trends in the data. Any unusual or unexpected results are then re-reviewed to ensure that data accurately reflect the case details. Ongoing review and cleaning of historical data are undertaken to maintain the quality of the core dataset. Accordingly, numbers may vary slightly between this report and previous publications. In addition to these formal quality control methods, throughout these processes, all project staff involved - the data entry personnel and the Research Fellows responsible for analysis - communicate to identify trends, anomalies or interesting patterns noticed in the current dataset. Definition of drug involvement/overdose used in this report The attribution of a drug or substance as being involved in the event is formed on the basis of ambulance paramedic mention of the involvement of these substances, established through paramedic clinical assessment, patient self-report or information provided by someone else at the scene, such as family, friends or associates. The drug categories reported indicate the involvement of these drugs however other drugs and alcohol may have also been ingested (with the exception of Alcohol which is an exclusive category in this report). The core criterion project staff use in determining the involvement of a drug or substance is: “Is it reasonable to attribute the immediate or recent (not merely chronic) over- or inappropriate ingestion of the substance or medication as significantly contributing to the reason for the Ambulance Victoria attendance?” Alcohol-related events Alcohol-related cases are defined as those cases attended by ambulance where assessment of causality is that only alcohol, as far as could be ascertained, was involved in causing the attendance. These cases usually relate to alcohol intoxication and poisoning, but may include alcohol-related injuries. All amphetamine-related attendances This category is an aggregation of the cases classified as either crystal methamphetamine- or other amphetamine-related events. Crystal methamphetamine-related attendances These cases are selected on the basis of ambulance paramedic mention of the involvement of “Crystal meth(amphetamine)”, “Ice”, etc., established through patient self-report or information provided by someone else at the scene, such as family, friends or associates. Data on “crystal methamphetamine/ice” as the type of amphetamine involved in events have been collected from October 2002. Other amphetamine-related attendances These cases are selected on the basis of ambulance paramedic mention of the involvement of any form of amphetamine excluding “crystal meth(amphetamine)”, “ice”, etc., established through patient self-report or information provided by someone else at the scene, such as family, friends or associates. It should be noted that crystal methamphetamine cases cannot be excluded from the Ambo Project: Alcohol and Drug related Ambulance Attendances – 2012/13 Annual Report Page 9 ”other amphetamine” category with certainty. Therefore, the other amphetamine category should be viewed as excluding crystal methamphetamine cases as far as could be ascertained. All heroin-related attendances This category is an aggregation of the cases classified as either heroin overdose or other heroinrelated events. Heroin overdose It is difficult to define heroin overdose (Darke & Zador, 1996). For the data presented in this report, Heroin overdose refers to a positive response to the administration of naloxone (an opioid antagonist) for those people attended by an ambulance and where there was no indication that the overdose resulted from another opioid such as morphine or methadone. Other drugs and alcohol may also have been ingested. Other heroin-related attendances These are cases where evidence of heroin use is established through the clinical assessment of the ambulance paramedic and/or by the patient or his or her associates at the scene, but naloxone was not administered. In these cases too, other drugs and alcohol may have also been ingested. Ecstasy-, gamma-hydroxybutyrate (GHB)-, cannabis-, cocaine- and inhalant- related attendances These cases are selected on the basis of ambulance paramedic mention of the involvement of these substances, established through patient self-report or information provided by someone else at the scene, such as family, friends or associates. Data on GHB as the drug involved in events have been collected from March 2001. Benzodiazepine-related attendances This category includes drugs such as alprazolam, bromazepam, clobazam, clonazepam, diazepam, flunitrazepam, lorazepam, midazolam, nitrazepam, oxazepam, temazepam and triazolam. This category also includes the sedatives zolpidem and zopiclone. Anticonvulsant-related attendances Selected anticonvulsants include the drugs carbamazepine, gabapentin, lamotrigine, oxcarbazepine, pregabalin, sodium valproate, tiagabine and topiramate. For the Ambo Project, the only anticonvulsants coded are those that are used - on- or off-label - in treating psychiatric conditions, primarily bipolar disorder. Data pertaining to anticonvulsant-related attendances were collected from May 2000. Antidepressant-related attendances Included in this category are drugs such as amitriptyline, citalopram, clomipramine, desvenlafaxine, dothiepin, doxepin, duloxetine, escitalopram, fluoxetine, fluvoxamine, imipramine, mianserin, mirtazapine, moclobemide, nortriptyline, paroxetine, phenelzine, reboxetine, sertraline, tranylcypromine, trimipramine and venlafaxine. Antipsychotic-related attendances These include drugs such as amisulpride, aripiprazole, chlorpromazine, clozapine, droperidol, flupenthixol, fluphenazine, haloperidol, olanzapine, paliperidone, pericyazine, pimozide, quetiapine, Ambo Project: Alcohol and Drug related Ambulance Attendances – 2012/13 Annual Report Page 10 risperidone, thioridazine, trifluoperazine, ziprasidone, zuclopenthixol. This category also includes lithium. Opioid analgesic-related attendances This category includes drugs such as dextropropoxyphene (with or without paracetamol), fentanyl, hydromorphone, morphine, oxycodone, pethidine and tramadol, but excludes methadone and buprenorphine. Other analgesic-related attendances Other analgesics includes drugs such as aspirin, ibuprofen and paracetamol, either alone or in combination with other drugs (excluding dextropropoxyphene but including codeine). Please note that for all categories, values of less than five cases are not reported. Mapping of alcohol- and drug-related ambulance attendances The ability to map ambulance attendances for alcohol- and drug-related harm provides unparalleled opportunities to explore clustering of harms in local areas at the micro level for populations and subpopulations of interest. The production of maps of patterns and clusters of alcohol- and other drugrelated harms requiring ambulance attendance addresses policy priorities and also the need to develop strategic and timely responses to alcohol and drug related harms. For each of the main drug groups included in this report, maps of concentrations of alcohol- and drug-related ambulance attendances are provided for 2012/13. These maps are presented at two levels of geographic specificity - by local government area (LGA) and by postcode of attendance for both metropolitan Melbourne, and for Victoria. Please note that postal area may not specify which part of Victoria is regional or Melbourne metropolitan area. Key maps of LGAs are provided in the Appendix. Population estimates This report uses Australian Bureau of Statistics Estimated Resident Population (ERP) data to calculate population rates. These figures are estimated at June 30 each year. For the 2011/12 financial year, ERP data from 2011 has been used as the denominator, whilst for the 2012/13 financial year, 2012 ERP data has been used as the denominator. Ambo Project: Alcohol and Drug related Ambulance Attendances – 2012/13 Annual Report Page 11 Chapter 3: Alcohol-Related Attendances (Alcohol Only) Alcohol-related cases are defined as those cases attended by ambulance where assessment of causality is that only alcohol, as far as could be ascertained, was involved in causing the attendance. No other drugs or substances are known to be involved in these events. These cases usually relate to alcohol intoxication and poisoning, but may include alcohol-related injuries. Characteristics of alcohol-related attendances The data displayed in Table 3 shows characteristics of alcohol-related ambulance attendances in metropolitan Melbourne and regional Victoria for 2011/12 and 2012/13. The daily numbers of alcoholrelated attendances were significantly higher in 2012/13 than in 2011/12 (p<0.001) in both metropolitan Melbourne and regional Victoria. The mean age of patients attended increased in 2012/13 (p<0.001) in metropolitan Melbourne and regional Victoria. In metropolitan Melbourne and regional Victoria, the proportion of cases occurring in public spaces decreased (p<0.001) when compared with 2011/12. In both metropolitan Melbourne and regional Victoria, the proportion of alcohol-related attendances where the patient was transported to hospital increased significantly in 2012/13 when compared with the previous year (p<0.001).

Day of week and time of day of alcohol-related attendances In both metropolitan Melbourne and regional Victoria, the distribution of alcohol-related ambulance attendances across the days of the week was consistent in both 2011/12 and 2012/13, with the highest proportion of attendances occurring on Saturdays and Sundays and lowest on Mondays. The peak time for alcohol-related attendances in 2012/13 was between 12pm and 6am on Saturday and Sunday. The distribution of alcohol-related attendances over times of day and days of week is Ambo Project: Alcohol and Drug related Ambulance Attendances – 2012/13 Annual Report Page 12 presented in Figure 1 and Figure 2, and indicates that the trend in temporal variation in attendances was similar in 2011/12 and 2012/13.

In metropolitan Melbourne, the three LGAs with the highest rates for alcohol-related ambulance attendances in 2012/13 were Melbourne, Port Phillip and Yarra (Table 4). Rates of attendances increased across the majority of LGAs when compared with the previous year. The only exception was Boroondara. Melbourne retained its ranking as the LGA with the highest rate of alcohol-related attendances in metropolitan Melbourne. Nillumbik remained the LGA with the lowest rate of alcohol-related attendances in metropolitan Melbourne. In regional Victoria, although Greater Geelong was the LGA with the highest proportion of alcoholrelated ambulance attendances in 2012/13, Yarriambiack and Warnambool had the highest population rates, followed by Latrobe and Greater Shepparton (Table 5). Rates of attendances increased across the majority of LGAs when compared with the previous year. The exceptions were Murrindindi, Hepburn, Gannawarra and Buloke, showing decreases in population rates for alcoholrelated ambulance attendances. Mapped alcohol-related attendances for 2012/13 are presented at LGA level (Map 1 and Map 2) and postcode (Map 3) for metropolitan Melbourne and regional Victoria.

Data on “crystal methamphetamine/ice” as the type of amphetamine involved in events have been collected from October 2002. Characteristics of crystal methamphetamine-related attendances As shown in Table 15, in 2012/13 across Victoria, the daily rate of crystal methamphetamine-related attendances was significantly higher than in 2011/12 (p<0.001). In metropolitan Melbourne, significant decreases were seen in the proportion of cases where alcohol was involved, and where events occurred in public spaces (p<0.05), while significant increases were noted in the proportion of events co-attended by police, and cases where the patient was transported to hospital (p<0.01). In regional Victoria, there was a significant increase in the proportion of events co-attended by police (p<0.001).

In metropolitan Melbourne, the three LGAs with the highest rates for crystal methamphetaminel-related ambulance attendances in 2012/13 were Melbourne, Port Phillip and Yarra (Table 16). Rates of attendances increased across the majority of LGAs when compared with the previous year. The only exception was Maribyrnong. Melbourne retained its ranking as the LGA with the highest rate of crystal methamphetamine-related attendances in metropolitan Melbourne. Bayside was the LGA with the lowest rate of crystal methamphetamine-related attendances in metropolitan Melbourne. In regional Victoria, although Greater Geelong was the LGA with the highest proportion of crystal methamphetamine-related ambulance attendances in 2012/13, Latrobe, Moorabool and Horsham had the highest population rates, followed by Greater Bendigo and Greater Geelong (Table 17). Rates of attendances increased across all LGAs when compared with the previous year (where numbers allowed for comparison).

In metropolitan Melbourne, the three LGAs with the highest rates for benzodiazepine-related ambulance attendances in 2012/13 were Yarra, Frankston and Melbourne (Table 22). Rates of attendances increased across the majority of LGAs when compared with the previous year. The exceptions included: Yarra, Melbourne, Maribyrnong, Greater Dandenong and Bayside. Melbourne did not retain its ranking as the LGA with the highest rate of benzodiazepine-related attendances in metropolitan Melbourne. Rather Yarra had the highest rate. Manningham remained the LGA with the lowest rate of benzodiazepine-related attendances in metropolitan Melbourne. In regional Victoria, although Greater Geelong was the LGA with the highest proportion of benzodiazepine-related ambulance attendances in 2012/13, East Gippsland, Benalla and Bass Coast had the highest population rates, followed by Greater Shepparton and Mount Alexander (Table 23). Rates of attendances increased across the majority of LGAs when compared with the previous year. The exceptions were Greater Shepparton, Latrobe, Horsham, Ballarat, Central Goldfields, Baw Baw, Wodonga, Wangaratta, Northern Grampians and Murrindindi, showing decreases in population rates for benzodiazepine-related ambulance attendances.

Other drugs and alcohol may also have been ingested. Characteristics of heroin overdose attendances (responding to naloxone) The data displayed in Table 30 shows the characteristics of heroin overdose ambulance attendances in metropolitan Melbourne and regional Victoria in 2011/12 and 2012/13. The daily rate of heroin overdose attendances in metropolitan Melbourne in 2012/13 was significantly lower than in 2011/12 (p<0.01). There was a significant increase in the mean age of patients in 2012/13 when compared with 2011/12 (p<0.001). In regional Victoria, the proportion of cases where the patient was transported to hospital decreased non-significantly.

In metropolitan Melbourne, the three LGAs with the highest rates for antipsychotic-related ambulance attendances in 2012/13 were Frankston, Port Phillip and Melbourne (Table 46). Yarra rates substantially reduced from the previous year where it had been in the top three. Frankston retained its ranking as the LGA with the highest rate and number of antipsychotic-related attendances in metropolitan Melbourne. Frankston rates and numbers of attendances increased substantially over the two years presented. In regional Victoria, although Greater Geelong was the LGA with the highest proportion of antipsychoticrelated ambulance attendances in 2012/13, East Gippsland, Northern Grampians and Greater Bendigo had the highest population rates, followed by Gannawarra and Latrobe (Table 47).

There was a significant increase (p<0.05) in the proportion of cases where the patient was transported to hospital in metropolitan Melbourne compared with 2011/12. When compared with 2011/12, the proportion of attendances where alcohol was also involved remained unchanged in metropolitan Melbourne. Due to the small number of cocaine-related attendances in regional Victoria, most characteristics had too few cases to be reported.

Day of week and time of day of cocaine-related attendances As shown in Figure 69 and Figure 70, the distribution of metropolitan Melbourne and regional Victoria cocaine-related attendances across the times of the day and days of the week in 2011/12 and 2012/13 were highly variable - which is due to the small numbers of attendances. The peak day (aggregating all times) in 2012/13 in metropolitan Melbourne was Sunday, while the peak days in regional Victoria were Friday and Sunday. The peak time (aggregating all days) in 2012/13 in metropolitan Melbourne was between midnight and noon, while the peak time in regional Victoria was either between noon and 6pm or between midnight and 6am.

In metropolitan Melbourne, the three LGAs with the highest rates for cocaine-related ambulance attendances in 2012/13 were Melbourne, Yarra and Port Phillip. Melbourne also had the highest proportion of attendances. Due to the small numbers of cocaine-related attendances, small changes may result in apparently large differences in proportions presented. In 2012/13 there were no LGAs in regional Victoria where more than four cocaine-related attendances occurred. Mapped cocaine-related attendances for 2012/13 are presented at LGA (Map 40 and Map 41) and postcode (Map 42) levels.
