E1.Choosing Wisely: The Challenge of Low-Value Care. Sam Shortt

Slide 1 Choosing Wisely Canada The Challenge of Low-Value Care 20 February 2015 2015 Quality Forum Vancouver, BC Dr. Sam Shortt ‹#› Presentation Definition Size & causes of unnecessary care Choosing Wisely Canada (CWC) origin & approach Implementation Evaluation Useful resources Conclusion ‹#› What is Choosing Wisely? Choosing Wisely is a physician-initiated campaign to help physicians and patients engage in informed conversations about unnecessary tests, treatments and procedures. Wise choices will improve the quality of clinical care and will enhance stewardship of scarce resources. ‹#› # of MDs 100% 0% Frequency of a specific clinical activity Over Use What is the Target of Choosing Wisely? Approximate zone of CPG compliance, usual practice, available options, etc. Under Use How Big is the Problem? IOM estimates 30% of care in US is unnecessary Examples Service Condition(s) No. of Studies Range of Overuse Rates, % (2000–2009) Coronary angiography MI, CAD 17 8.0 – 21.8 Coronary revascularization CAD 16 1.4 – 14.0 Upper endoscopy Bleeding (upper), PUD 7 19.0 – 23.0 Radiographs in acute respiratory illnesses Bronchiolitis, asthma 5 32.0 – 72.0 Colonoscopy Colon CA 4 23.0 – 60.8 Antibiotics URI, acute bronchitis 59 2.0 – 89.0 Bronchodilators Obstructive diseases 6 30.0 – 81.0 Korenstein D, et al. Overuse of health care services in the United States: an understudied problem. Arch Intern Med. 2012; 172:171-8 ‹#› No Comparable Canadian Data In a Saskatchewan study of pre-school children with respiratory infections almost half of antibiotic prescriptions were not indicated on the basis of evidence-based guidelines. Wang E, et al. Clin Infect Dis. 1999; 29(1):155-60 An Ottawa and Edmonton in-hospital study of lumbar spine MRI - 28.5% were deemed inappropriate and 27.2% of uncertain value. Emery et al. Overuse of Magnetic Resonance Imaging JAMA Intern Med 2013;173(9):823-825. …As in the US, the 30% figure seems a not unreasonable estimate. ‹#› Multiple Causes of Low-value Care Physician habit Patient demand Physician lack of knowledge Fear of litigation Financial incentives Specialist requirements for referrals “More or New is Better” fallacy Time pressures See: Scott I A, Elshaug AG.

MOH<C, CMA., Health Canada April 2014: 8 lists released; Oct. 2014: another 11 lists released Over 35 specialties are now engaged with lists in future to be released in small groups or individually as available over 2015.

Endorsed National Association of Federal Retirees, Patients Canada, and others ‹#› Choosing Wisely Canada Approach…1 Physicians: List development: National specialty societies are free to determine the process for creating their lists, as long as they are done in accordance with the following principles: The development process is thoroughly documented and publicly available Each recommendation is within the specialty’s scope of practice Tests, treatments or procedures included are those that (a) are frequently used, and, (b) may expose patients to harm or stress. Each recommendation is supported by evidence Messaging ‹#› Implementation Multi-stakeholder Implementation Committees in Ontario; Alberta; and conjointly in the 4 Atlantic provinces. Some common themes BASIC INTERMEDIATE ADVANCED Promote awareness locally Educate physicians √ Educate patients √ Make policy changes Support QI initiatives Measure and evaluate EMR/CPOE integration Audit and feedback ‹#› BASIC: Screensaver, North York General ‹#› Available at www.choosingwiselycanada.org ‹#› Basic: the Early Adopters Collaborative Informally monthly teleconference for sharing tactics and stories Over 26 regional health authorities and hospitals from coast to coast participate Among them: Fraser Health Authority Vancouver Coastal Health Sign up at: www.choosingwiselycanada.org ‹#› Intermediate: Evaluation & Measurement Two broad themes: Culture change in medical practice Positive change in utilization Culture Change Baseline surveys off physician attitudes have been done, e.g. CMA e-panel: Patients drive inappropriate use of services more often than physicians do. 58% agree or strongly agree I need more support and/or tools to help me make decisions about which services are inappropriate for my patients. 69% agree or strongly agree The primary responsibility for decreasing inappropriate use of services rests with physicians. 76% agree or strongly agree ‹#› 17 Evaluation…2 Utilization: Gathering Baseline Data 1. Don’t repeat dual energy X-ray absorptiometry (DEXA) scans more often than every 2 years. 2.

The medical profession, appropriately, has taken ownership of this issue through the rapidly expanding Choosing Wisely campaign. This initiative has the potential to improve quality of care and stewardship of scarce resources. The challenges are less in list creation than in ensuring uptake in clinical practice and document the ensuing impact. A final challenge: the message is about quality, not cost. ‹#› Chart1 0.1425665995 0.3625982902 0.5810469872 0.369840776 ECG ECGs ECG 2012 ECG LHIN Total surgeries n % % rank inc rank exc percentiles
