Texas Health Resources will team up with with CVS Caremark on walk-in medical clinics in CVS stores throughout North Texas, the Arlington-based health care system has announced. Under the agreement, doctors from the Texas Health Physicians Group will serve as collaborating physicians for 34 existing MinuteClinic locations in Dallas-Fort Worth in addition to seven more North Texas locations scheduled to open by early 2015. The physicians will work with nurse practitioners to provide medical oversight for primary care, Dr. Adam Myers, the physicians group's chief medical officer, told me in an interview.
