There is a new campaign in the Canadian medical landscape aimed at getting patients to make wiser choices regarding medical testing. The truth of the matter is that we doctors, often at the misguided request of our patients, order too many tests that have little scientific merit and waste truckloads of precious health care dollars. Check out a YouTube clip called "Choosing Wisely or visit www.choosingwiselycanada.org.
There are many examples where the science doesn't support the practice. Chest X-rays are a good start. There is no reason to do one on a healthy person without symptoms, even if they smoke. They rarely show something missed by a skilful clinician with a good stethoscope. Ankle x-rays for tissue pain are another example. They should only be used to look for the rare bone fracture. They cannot find a sprain, and the treatment is usually determined by the clinical examination. Repeating bone scans for osteoporosis in normal people on a yearly basis is completely without merit. The science tends to support an interval of closer to 10 years. New back sprains rarely need an MRI or CAT scan, but are the first thing patients ask for. All these tests come with a radiation exposure price. But some are totally justified and supported by science such as mammograms on women over 50 years of age and every two years.
Physical examinations have been reorganized to a three-year cycle. Part of the reason was "executive physicals". These were very high priced examinations paid for by third parties who made a huge array of unnecessary tests seem necessary for the privileged. These included ultrasounds, heart tests, food sensitivity tests and x-rays. Many of these patients would be given the "not so good" news in an envelope and then sent back to the OHIP system to get it all sorted out at large follow up costs.
Talking to a patient about improving their life-style takes a great deal of time and effort. Ordering a test, takes a minute. Sometimes, the test is just the thing to get the message across, and the balance between the two is truly part of the art of medicine. Other times, the anxiety around the tests is unbearable for patients. For example, some people obsess about blood pressure. They don't understand that blood pressure fluctuates with activity and feel very distressed if one reading is a little high. They will do almost anything to control that pressure except to lose weight, exercise and eat healthy. Seniors frequently request cholesterol checks, sometimes every few months. It seems like a lottery to me at times. If they get the right number, somehow it makes all the bad food they have been eating seem okay?
My grandmother advocated a simple and inexpensive test. She would suggest taking a good long look in the mirror before taking a lot of time and effort to prove it isn't so. Have a frank discussion with you doctor about which tests are necessary and make the choice together.
