Choosing Wisely, or when to say ‘Whoa!’ to unnecessary medical tests and treatments




A potentially game-changing health-care initiative is underway in the USA. The Choosing Wisely campaign is asking top physicians in different speciality areas (e.g. cardiology, obstetrics, radiology) to identify the top five procedures or tests that are routinely ordered by doctors but not supported by research. More than 60 specialty societies have joined the campaign since its inception in 2012.

This campaign is about more than saving money. Unnecessary tests and procedures not only increase health-care costs, but also put patients at risk. Take CT (computed tomography) scans as an example. A single CT scan delivers between 150 and 1,100 times the radiation of a conventional x-ray. According to Scientific American, the National Cancer Institute estimates that the 72 million CT scans performed in the USA in a single year (2007) could cause up to 29,000 future cancer cases. That increase is equivalent to about 2 percent of the total number of cancers diagnosed nationwide every year. In some situations, CT scans are completely appropriate and the benefits outweigh the risks. Many people, however, receive unnecessary CT scans and, along with them, unneeded doses of radiation. 

On a recent perusal of the Choosing Wisely website, I found no less than 57 lists of ‘Five Things Physicians and Patients Should Question’ created by different medical speciality societies. Patient-friendly versions also have been produced in collaboration with Consumer Reports. The Canadian Medical Association has recently joined the effort and will be producing its own Top 5 lists in partnership with nine Canadian physician speciality societies.

Patients are an important part of the campaign because as care partners, they have a responsibility to ask questions about the pros and cons of different treatment options. And sometimes, patients ask for tests and treatments that are not in their best interests. Two classic examples are requests for imaging (X-ray, CT or MRI scans) in the first few weeks of a new episode of low back pain, or requests for antibiotics (which kill bacteria) when all signs point to a viral infection. Research has shown that physicians can be swayed by patient requests for specific tests or treatments even when they disagree, sometimes because they want to please their ‘customer’ and sometimes because they want to avoid potential lawsuits.

Of course, general lists of things to avoid can never substitute for a skilled clinician making decisions in collaboration with the patient. And the American Board of Internal Medicine (ABIM) Foundation, who is funding the campaign, notes that Choosing Wisely recommendations should not be used to establish coverage decisions or exclusions. Rather, they are meant to spur conversation about what is appropriate and necessary treatment. As each patient situation is unique, physicians and patients should use the recommendations as guidelines to determine an appropriate treatment plan together.
