That’s you, and me, and that guy. “Despite existing recommendations — testing before low-risk procedures was common … significant regional and institution-level variation was present, with a 30 -fold difference between institutions with the lowest and highest rates of ordering tests. ” Kirkham K.

Everyone is Choosing Wisely • Don’t perform stress cardiac imaging or advanced noninvasive imaging as a pre-operative assessment in patients scheduled to undergo low-risk non-cardiac surgery. Cardiology • Don’t order annual electrocardiograms (ECGs) for lowrisk patients without symptoms. Cardiology • Don’t routinely perform preoperative testing (such as chest X-rays, echocardiograms, or cardiac stress tests) for patients undergoing low risk surgeries. Internal Medicine • Don’t order screening chest X-rays and ECGs for asymptomatic or low risk outpatients. Family Medicine u. Ottawa. ca

Even These Guys are Choosing Wisely • Don’t perform stress cardiac imaging or coronary angiography in patients without cardiac symptoms unless high-risk markers are present. Nuclear Medicine • Avoid routine preoperative laboratory testing for low risk surgeries without a clinical indication. Pathology • Avoid admission or preoperative chest X-rays for ambulatory patients with unremarkable history and physical exam.

Conclusion • Synthesis of observational studies in 1997 • Dissemination in guideline form in 2003 • In Ontario 2008 -2013, we ordered ECGs – 30% of low risk surgeries – 3 – 80% rates in different institutions • There is work to do. • Engagement • Ethical application u. Ottawa. ca

Questions, for you … 1. What is the greatest barrier to reducing testing in your practice? 2. What would it take to make your most conservative colleague happy? 3. Would your surgeons and administration buy in? 4. Will your patients feel undertreated? 5. How will you react if your patient questions why they are being tested? u. Ottawa. ca
