Maybe both you and the author are right. To maintain their incomes in the face of falling reimbursments, primary care doctors ar so busy seeing too many patients in a day they can neither critique the literature nor counsel patients effectively.
But Darshak is right about the lack of critical skills. Here's an example: How many physicians reading the original Vioxx VIGOR paper picked up on the fact that the number of patients in the treatment group who suffered a cardiac event exceeded the number who were protected from a GI bleed? The data were there for everybody to see, but the paper was written in such a way that this essential fact was buried. And that was in the NEJM.
So there are three problems here: 1) the journals are filled with junk science and obscured data; 2) PCPs don't always have the training to pick apart studies; and 3) PCPs are so pressed for time, they don't always provide the coordinated care that patients really need.
Each of those problems has a solution. Better peer review. Higher reimbursements for PCPs. Better training in medical school and getting pharma out of the business of underwriting CME.
Cutting CMS reimbursements is the absolutely wrong thing to do.
