Physicians who do not like pay-for-performance programs may rue the day they started complaining about them.

P4P programs, which generally keep patients out of the mix, are easy to accept in comparison to public rating systems that reward patients, via lower copayments, for learning which physicians offer the highest quality care at the lowest cost and taking their symptoms to those doctors.

Physicians are understandly nervous about ratings, which can be misleading or downright wrong. But payers–frustrated that the P4P movement is going nowhere fast–are looking for new ways to reward physicians who will get in line with payers’ cost-effectiveness goals, and physician ratings is one of them.

In Massachusetts, the state medical society sued Group Insurance Commission, which buys insurance for more than 300,000 current and retired state employers, claiming that its physician rating system “fraudulently misleads patients and unfairly affects the reputation of physicians.”

No quaking in Massachusetts. Other payers are undaunted. As reported in the Boston Globe, two of that state’s biggest health plans are moving ahead with physician rating systems instead of waiting for the lawsuit to play out.
