PROMs to inform patient care: What are we doing well? What could we do better? Professor Madeleine King Cancer Australia Chair in Cancer Quality of Life Director, Quality of Life Office University of Sydney Overview • • • • • Standards and standardisation Clinical trials Clinical care Improvement and innovation Education Standards and standardisation • • • • Terminology Measurment tools Metrics Standards for instrument development and PRO reporting “Quality of life”: LACK OF STANDARD DEFINITION "Quality of life is a vague and ethereal entity, something that many people talk about, but which nobody clearly knows what to do about.“ Campbell et al, 1976 “The idea has become a kind of umbrella under which are placed many different indexes dealing with whatever the user wants to focus on.” Feinstein, 1987 “Concepts of health often lack clarity... The term ‘quality of life’ also has many meanings.” Patrick & Erickson, 1993 Terminology – a source of confusion “Health-related QOL (HRQOL) refers to the extent to which one’s usual or expected physical, emotional, and social well-being are affected by a medical condition or its treatment.” Broad umbrella: ‘Quality of Life’ ‘Health-related quality of life (HRQOL)’ Symptoms Side-effects Diseasespecific HRQOL Generic HRQOL QOL Well being ‘health-related - HRQOL’ Cella, D. (1995). Measuring quality of life in palliative care. Seminars in Oncology, 22, 73-81. ‘Patient-reported outcomes PRO’ ‘A measurement based on a report that comes directly from the patient about the status of a patient’s health condition without amendment or interpretation of the patient’s response by a clinician or anyone else.’ DEFINITIONS “HRQOL is a multidimensional construct encompassing perceptions of both positive and negative aspects of dimensions, such as physical, emotional, social, and cognitive functions, as well as the negative aspects of somatic discomfort and other symptoms produced by a disease or its treatment.” Revicki, D.A., Osoba, D., Fairclough, D., Barofsky, I., Berzon, R., Leidy, N.K., Rothman, M. (2000). Recommendations on health-related quality of life research to support labeling and promotional claims in the United States. Quality of Life Research, 9(8), 887-900. DEFINITIONS FDA Guidance (2009) Emerging term: Patient-reported Experiences (PREs) Process of care • Expectations, experience, perceptions, satisfaction with health services, care providers, information UK NHS: “The way people experience health services is an important component of the quality of care” TOOLS – a plethora! H E L P !!! Too many! Tools – Core Outcome sets Core Outcome Sets • the minimum that should be measured and reported in all clinical trials of a specific condition • also suitable for use in clinical audit and other research • Facilitate comparison and combination of results • does not imply that outcomes in a particular trial should be restricted to those in the relevant core outcome set • COMET encourages researchers to continue to explore other outcomes as well. • COMET aims to collate and stimulate relevant resources, both applied and methodological, to facilitate exchange of ideas and information, and to foster methodological research in this area. E.g. OMERACT –Rheumatology Developing a Core Domains Set Innovation: Standardised metrics PROMIS www.nihpromis.org PROs – what’s in the toolkit? There is no “best” tool choose the right tool for the job Dynamic field – new tools and measurement innovations NIH investment in PROMIS® Innovation: PRO-CTCAE • NIH-backed PROM R&D • Patient-reported outcomes version of the NCI’s common toxicity criteria - standard lexicon for adverse event reporting, the CTCAE • in development under a contract from the NCI • PI: Ethan Basch • Web-based platform • https://wiki.nci.nih.gov/displa y/PROCTCAE/ – 100 million dollars (US) over 10 years – Grants led by many of the USA’s leaders in PROM development over past 30 years Click to edit Master title style 14 What is PROMIS®? • Patient Reported Outcomes Measurement Information System • System of generic PROMS that are highly reliable, valid, flexible, precise, and responsive • Includes measures for wide range of domains & Click to edit Master title style subdomains of physical, mental, and social functioning and symptoms • For specific domains, short-forms (fixed) and computer-adaptive test (CAT, “dynamic”) • Designed for electronic administration Innovation: Computer Adaptive Testing (CAT) Click to edit Master title style – Short-forms can be pencil-&-paper What makes PROMIS® better than anything else? • The promise of PROMIS – Do away with the floor and ceiling effects of the legacy instruments – Do away with the “Tower of Babel” in PROMS – the inability to compare and interpret across scales and domainsto edit Master title style Click – facilitate comparison and combination of results from multiple studies – Simplify administration via computer-based administration, scoring, and reporting – Reduce response burden … ONLY CATS – Improve measurement precision … ONLY CATS How does it work? • By forming “banks” of items, then calibrating them – Calibration puts all items on a common metric – Within a domain, results are comparable for long-forms, short-forms and CATs, regardless of which items are Click assessedto edit Master title style Example: Physical Function spectrum Scientific standards in PRO measurement • Questionnaires as ‘instruments’ to measure subjective phenomena – Psychometrics 0 • Measurement properties 50 10 0 Physical Functioning • Are you able to run five miles? • Are you able to run or jog for two miles? • Are you able to walk a block on flat ground? • Are you able to walk from one room to another? • Are you able to stand without losing your balance for 1 minute? • Are you able to get in and out of bed? Examples of short-forms that cover different parts of the spectrum Depression Short Form – Validity, reliability, sensitivity – Interpretability • Ongoing refinement and evolution Explanations and benchmarks set for PROs by FDA C no depression Depression Short Form Depression Short Form B A mild depression moderate depression severe extreme depressio depression n http://www.fda.gov/downloads/Drugs/ GuidanceComplianceRegulatoryInformation/Guidances/ UCM193282.pdf Depression Item Bank Item 1 Item 2 Item 3 Item 4 Item 5 Item 6 Item 7 Item 8 Item 9 Item n EORTC module development http://groups.eortc.be/qol/manuals Clinical trials • Phase 1 – focus groups with patients to identify range of issues that matter to patients across stages and treatments • Phase 2 – item generation • Phase 3 – validation and psychometrics • Phase 4 – international field testing Whole process typically takes several years Evidence about candidate therapies JAMA 2013 1. 2. 3. 4. 5. the PRO be identified as a primary or secondary outcome in the abstract a description of the PRO hypothesis and relevant domains (if a multidimensional PRO tool has been used) be provided evidence of PRO instrument validity and reliability be provided or cited the statistical approaches for dealing with missing data be explicitly stated PRO-specific limitations of study findings and generalizability of results to other populations and clinical practice be discussed. • Primary management +/- Adjuvant Therapy • Metastatic disease • Survivorship • End of life Morbidity & toxicity for cure Extending survival, symptom control, toxicity trade-off Why include PRO endpoints? • Choosing therapy – – – – Primary outcome Support primary outcome (often a survival endpoint) Counterbalance primary outcome Differentiate when equivalent on primary outcome • Enriching understanding – Benefits or risks – Prognosis – Under-evaluated populations • Improving methods – Prognostic determinant (stratification) – Measurement advances Au et al., 2010 http://promotion.gimema.it How well are we doing ? Success Online The PROMOTION Registry • a registry of all cancer Randomized Controlled Trials (RCTs) with a Patient-Reported Outcome (PRO) endpoint published since 2004 • contains nearly 700 PRO-RCTs conducted across a wide range of cancer specialties that have enrolled, overall, more than a quarter of a million of patients • GOAL: to address research questions about the use and the added value of PROs assessment in cancer clinical trials • Several collaborations are now ongoing with a number of Universities and research groups dedicated to quality of life and PRO research in oncology • Reviews/publications so far: ISOQOL Taskforce for Best Practice in PROs in Clinical Trials • Co-Chairs: Melanie Calvert (UK), Michael Brundage (Canada) and Madeleine King (Aus) • Developing an evidence- and consensus-based PROtocol Checklist • Hypothesis: more complete PRO components of protocols results in higher quality PRO evidence, and more complete reporting in papers – Brain, prostate, gyne – H&N underway with Univ Sydney QOL Office Checklist for PROtocols • Importance of the protocol – Procedures for good conduct of the trial – success or failure of a trial may depend on how well the protocol was designed and written – outlines procedures for good conduct of the trial – all relevant requirements so the study can be implemented uniformly by all sites and staff – detailed and clearly worded • These general points apply just as much to PRO assessment as to any other aspect of a Chan et al., 2013 trial QOL Office PROtocol Checklist Available on QOL Office Website pocog.org.au/qoloffice Innovation Clinical care • Translation of clinical trial evidence into policy and care • Direct evidence • Initiatives and evaluation Magnitude of Clinical Benefit Scale • Standardised scoring of clinical benefit in studies of new agents/approaches in the management of cancers • graded 5, 4, 3, 2, 1, where grades 5 and 4 represent a high level of proven clinical benefit • Preliminary grading based on survival outcomes - hazard ratio for DFS/OS and median survival gain as well as late survival advantage and is reported on a 4 point scale. • Preliminary scores can be upgraded by 1 point when the experimental arm demonstrates improved QoL or delayed deterioration in QoL using a validated scale or substantial reduction in grade 3 or 4 toxicity. • A score of 5 can only be achieved when optimal survival outcomes are further enhanced by data indicating reduced toxicity or improved quality of life. Translation of evidence from clinical trials into policy and care • Same challenges for PROs as for any other endpoints – Behaviour change • Additional challenges – Many questionnaires/scales • Cochrane PRO Methods Group – The quality of the PRO evidence and reporting – Interpretation in terms of clinical importance / minimally important difference (MID) Direct evidence: effect of PRO assessment in clinical practice • 5 systematic reviews to date – Valderas et al. (2008) – Frost et al. (2007; cancer-specific) – Marshall et al. (2006) – Espallargues et al. (2000) – Greenhalgh et al. (1999) Example: PROMs in Clinical Care Screening for psychosocial problems Step 1: Routine assessment of patient wellbeing Patient completes online survey in waiting room Acceptable strategy? • 60% of 229 patients had no previous contact with computers • 89% happy to complete at each visit • 96% happy for oncologist to get summary of results • 99% usually have time to do while waiting for doctor Newell et al, 1997; Boyes et al, 2002 PRO assessment in clinical practice What the evidence says: Improves: – communication – awareness Equivocal: – patient management – satisfaction – PROs / HRQoL + + +/+/+/- Does NOT increase consultation time Routine Screening Model Step 2: Real time feedback to clinical team • Summary report placed in medical file includes: • patient outcomes • score interpretation • recommended interventions (triage) • Adapted patient version Routine Screening Model Step 3: Tailored psychosocial care Clinical team: • reviews the summary report • offers patients psychosocial care matched to type and level of need Other in-clinic initiatives • Lots of examples emerging – UK NHS – QA & quality improvement – NSW Integrated Care – Cancer Institute NSW • Challenges – – – – – Patient experiences v outcomes Which PREMs and PROMs? When? How to integrate with eHealth records? How to get staff on board? What will the data be used for? • Benchmarking? Managing individual patients? • If managing individual patients, are measure error v signal? – Evaluation - collecting baseline data as comparator Routine Screening Model Step 4: Benchmarking • Annual benchmarking report comparing patient outcomes from each centre with all other treatment centres combined • Helps to identify strengths and weaknesses in service delivery Education http://www.isoqol.org/research/onlin e-education/archived-webinars ISOQOL Annual Conferences QOL Office Support / Resources Assistance with questionnaire selection & protocol development QOL Protocol Checklist 2-day w’shop each May/June QLQ v FACT content comparison spreadsheets for each cancer site Statistical analysis position paper FAQs Various QOL topics Searchable database of 350+ Patient Reported Outcome Measures (PROMs) CoMiDa form CRF to record PRO form completion rates & reasons for missing data.
