Minnesota: Workforce Turnover Contributes to Health Care Physician Trend Towards Working in Larger Practices

Physicians are increasingly working in large group practices — including hospital-owned systems.

The researchers assessed the size and hospital ownership of practices that physicians entered and exited.
