An interesting news item in PhillyBurbs.com today: Doylestown Hospital and Aetna announced an agreement this week that will give the hospital bonuses if it meets goals for patient care. The deal would reward the hospital for continuing its campaign to improve the care it provides to patients. Most of the U.S. health care system relies on a fee-for-service structure. Hospitals and doctors are paid according to the kind of health care they provide, not the quality of that care. The pay-for-performance agreement rewards hospitals that are better than their peers with bonus payments.
