The Integrated Healthcare Association (IHA) has released a list of the top-performing and most-improved physician groups in California as part of a pay-for-performance initiative. IHA included a total of 47 medical groups, including Brown & Toland Physicians, Palo Alto Medical Foundation, and Sutter Medical Group on the list. Under the pay-for-performance initiative, physician groups are eligible for incentive payments from seven participating health insurers. According to IHA, incentive payments this year are expected to reach about $40 million. IHA selected the physician groups based on criteria for meaningful use of health information technology and patients' overall care experience. It also assessed clinical quality measures for various topics, including cardiovascular, diabetes, musculoskeletal, preventative, and respiratory health.
