Another study on excessive testing, showing that it varies by city and region, with little evidence justifying such tests (and repeat testing). Good advice on keeping track of tests to be able to question whether another one needed. Quote:
We often don’t think of tests as having a downside, but they do. “This is the way whole cascades can start that are hard to stop,” Dr. [Gilbert] Welch said. “The more we subject ourselves, the more likely some abnormality shows up that may require more testing, some of which has unwanted consequences.”
Properly used, of course, diagnostic tests can provide crucial information for sick people. “But used without a good indication, they can stir up a hornet’s nest,” he said. And of course they cost Medicare a bundle.
An accompanying commentary, sounding distinctly exasperated, pointed out that efforts to restrain overtesting and overtreatment have continued for decades. The commentary called it “discouraging to contemplate fresh evidence by Welch et al of our failure to curb waste of health care resources.”
It is hard for laypeople to know when tests make sense, but clearly we need to keep track of those we and our family members have. That way, if the cardiologist suggests another echocardiogram, we can at least ask a few pointed questions:
“My father just had one six months ago. Is it necessary to have another so soon? What information do you hope to gain that you didn’t have last time? Will the results change the way we manage his condition?”
