Telling Doctors How to Practice Medicine

Here are two doctors writing about Medicare pay-for-performance guidelines:

Since 2003, the federal government has piloted Medicare projects at more than 260 hospitals to reward physicians and institutions that meet quality metrics…..

One key quality measure in the ICU became the level of blood sugar in critically ill patients….. A colleague who works in an ICU in a medical center in our state told us how his care of the critically ill is closely monitored. If his patients have blood sugars that rise above the metric, he must attend what he calls "re-education sessions" where he is pointedly lectured on the need to adhere to the rule. If he does not strictly comply, his hospital will be downgraded on its quality rating and risks financial loss. His status on the faculty is also at risk should he be seen as delivering low-quality care.

But this coercive approach was turned on its head last month when the New England Journal of Medicine published a randomized study….. Half of the patients received insulin to tightly maintain their sugar in the normal range, and the other half were on a more flexible protocol, allowing higher sugar levels. More patients died in the tightly regulated group than those cared for with the flexible protocol.

Similarly, maintaining normal blood sugar in ambulatory diabetics with vascular problems has been a key quality metric in assessing physician performance. Yet….. in one study of more than 10,000 ambulatory diabetics with cardiovascular diseases conducted by a group of Canadian and American researchers….. so many diabetics died in the group where sugar was tightly regulated that the researchers discontinued the trial 17 months before its scheduled end.

And just last month, another clinical trial contradicted the expert consensus guidelines that patients with kidney failure on dialysis should be given statin drugs to prevent heart attack and stroke.
