The University of Mississippi Medical Center is requiring its part-time doctors to take on full-time jobs there by January or they'll have to sever times with the teaching hospital.
UMC officials say the move, a new closed-staff policy, is designed to stabilize finances and better monitor care.
Officials say the policy affects about 20 positions and encourages doctors to refer patients inside the system.
The change doesn't affect those who teach part-time at the medical center or any private practice that doctors participate in as part of their clinical training.
Not all Jackson area hospitals are moving toward a closed staff, though.
