Study: Paying Doctors More for Better Care Seems to Work
However, its still not clear "whether the return on investment and the quality gains outweigh the financial and human effort," according to the Robert Wood Johnson Foundation, which funded the study.
Pay-for-performance programs have been gaining traction lately; the CMS (Centers for Medicare and Medicaid Services) has launched several programs in hospitals, chronic care management, and outpatient physician services.
For example, one program increase payment rates by 1 percent or 2 percent if hospitals perform well on 10 measures, like giving heart attack patients aspirin at arrival and discharge or getting antibiotics to pneumonia patients within four hours of their admission.
The projects represent the "largest experiment in the country" for assessing pay-for-performance, said Suzanne Delbanco, CEO of the Leapfrog Group, a consortium of health care purchasers that provided technical assistance to the programs.
The projects, she said, "provide some of the first tangible evidence that P4P incentives can raise the quality of patient care."
The study suggests that incentives need to be at least $5,000 per physician or perhaps as high as 10 percent of a physicians income to make a difference.
However, additional staffing and supportive infrastructure can also motivate physicians to hit quality targets.
The study had other recommendations. Successful pay-for-performance programs must involve physicians early in planning stages, make sure their quality measures are clinically relevant, and provide regular feedback.
Making physicians aware of quality improvement demands is also essential. In one case, physicians unaware of the program threw their bonus checks in the trash.
The study did not address whether P4P can work in traditional Medicare settings or a preferred provider network.
Most Americans get their care from PPOs, a loose network of providers that are not directed by any one plan.
However, Blue Cross of California is implementing a P4P project in San Francisco and plans to expand it statewide.
