Information about Group Practices

What is a Group Practice?

According to The Medical Group Management Association, a group practice is any relationship between three or more physicians who share facilities, expenses, profits and other resources like support staff and equipment.

Group practices tend to fall into two categories: those that organize around a particular medical specialty, like John Muir Health Network who specializes in obstetrics & gynecology, pediatrics, and those that encompass several specialties.

Why Group Practice?

As medicine became more complex in the twentieth century, the need for group practices made more sense. Physicians found it impossible to know everything about the emerging drugs and technologies on the medical landscape. In addition, the cost of providing a full range of diagnostic services, such as tests and X-rays, in one location became prohibitive to the individual practitioner. Hence, doctors from various disciplines began to team together in order to provide more comprehensive care to their community of patients.

Benefits of Group Practice:

  • Access to doctors from various disciplines for referrals and advice
  • Better coverage on weekends and off-hours
  • One-stop clinics for comprehensive care and testing
