This study found extensive variation in general internal medicine physician prices and that high-priced physicians provided fewer low-value services but had higher spending on these services.

Transitioning from Medicaid fee-for-service to Medicaid managed care was associated with a significant decrease in ambulatory utilization, especially among beneficiaries with 5 or more chronic conditions.

Physician practices intending to join Medicare accountable care organizations (ACOs) in 2012 had greater capabilities in health information technology, care management processes, and quality improvement methods than those not intending to join, but they still were far from using all recommended behaviors to manage risk.

Reports suggest that hospitals are acquiring physician practices. Data from 3 large surveys showed increased use of care management processes when hospital acquired practices.

This study examines the clinical effects of care management and quality improvement interventions implemented by physician groups on pay-for-performance success.
