For all the truly wondrous developments of modern medicine … it is distressingly ordinary for patients to get treatments that research has shown are ineffective or even dangerous. Sometimes doctors simply haven’t kept up with the science. Other times doctors know the state of play perfectly well but continue to deliver these treatments because it’s profitable — or even because they’re popular and patients demand them. Some procedures are implemented based on studies that did not prove whether they really worked in the first place. Others were initially supported by evidence but then were contradicted by better evidence, and yet these procedures have remained the standards of care for years, or decades.
He gives a great example of a doctor who prescribes epic quantities of a completely discredited drug:
When asked why he continues to prescribe atenolol so frequently in light of the randomized, controlled trials that showed its ineffectiveness, Huynh said, ‘I read a lot of medical magazines, but I didn’t see that.’ Huynh added that his ‘patients are doing fine with it’ and asked that any relevant journal articles be faxed to him.
Best practices can elude the best of us. It’s hard to keep up. Doctors are only human, after all.
There are many quotable passages from this important article. I will share it again, highlighting more.
