What are the advantages and disadvantages of group medical practice?
Physician groups come in all shapes and sizes and can deliver some key advantages to their provider members. But they’re not necessarily right for every clinician.
As far as benefits go, physician groups offer strength in numbers in a variety of ways:
- They give their members stronger footing in negotiations with payors, vendors, and other entities.
- By bringing together practitioners from multiple specialties and experience levels, physician groups support knowledge-sharing and continued learning.
- Having members across multiple specialties may also be more attractive to patients, who can access all their care at one location.
- Sharing costs reduces the financial liability of any given individual clinician and improves access to more expensive equipment and supplies.
Of course, the collaborative nature of physician groups also comes with its drawbacks:
- If provider interests aren’t aligned, conflicts can arise among members—especially those rising stars looking to make a name for themselves.
- Patients may see a different doctor at every visit, which can limit rapport between both parties.
- Younger, newer physicians usually have less sway over compensation and operations than their more experienced peers, meaning they may have to spend more time at work for less pay, depending on the group’s standards.
