Team Health Holdings Inc. (NYSE: TMH) agreed to buy Premier Physician Services, underscoring the continuing consolidation of doctor groups.

Based in Dayton, Ohio, Premier consists of more than 700 physicians and advanced practice clinicians that provide emergency, correctional care and occupational medicine services and staffing. The company says it provides care for more than one million patients annually. The transaction for undisclosed terms closed on October 21. Edgemont Capital Partners advised Premier on the sale.

Team Health's acquisition of Premier is the latest target for the Knoxville, Tennessee-based company. Since September, TeamHealth has grown through several deals, including the acquisition of Heartland Anesthesia Services PC, a Omaha, Nebraska-based provider of anesthesia management services.

The pace of M&A in the sector accelerated in 2014, as the rollout of the Affordable Care Act drives change in the U.S. health care system.
