Small group of Ontario family MDs orders too many unnecessary tests, study finds

A small group of Ontario family doctors is responsible for ordering a disproportionate amount of unnecessary screening tests on patients, new research shows.A paper published Friday in JAMA Network Open found that 441 primary care physicians in the province order nearly 40 per cent of tests considered “low-value.”This subset of the province’s 11,448 family doctors demonstrates “a general pattern of overuse,” according to the study by researchers at the Institute for Clinical Evaluative Sciences (ICES) and Women’s College Hospital.Lead author Dr. Sacha Bhatia said the findings are relevant because they can help better target future efforts to reduce low-value care.“The reality is that most doctors don’t get a lot of feedback on how they’re doing. But if we know who needs this the most, we can make big strides to improve the care patients get and save much needed health-care dollars in the process,” he said.Researchers looked at the ordering rates of four low-value screening tests between 2012 and 2016. They correctly hypothesized that physicians who frequently order one of these tests are more likely to frequently order at least one of the others as well.The four tests studied are:Repeat bone density tests, formally known as dual-energy X-ray absorptiometry (DXA) scans. This kind of screening is done to look for conditions such as osteoporosis. Evidence shows there is little value in having more than one of these scans within a two-year period.Electrocardiograms (ECGs) for patients 40 and older who are considered at low risk of cardiovascular disease. Chest X-rays for patients at low risk for cardiopulmonary disease. Pap tests on women younger than 21 and older than 69, a demographic considered at low risk for cervical cancer.These four tests were studied because of an abundance of evidence showing they are overused and that there is much variation in how often doctors order them.They have been identif ...
