Concerns escalated Tuesday about an impasse after the Detroit Medical Center and Wayne State University board leaders failed to release expected statements. The discussions, which are in mediation, aim to settle WSU\'s physician contract, which expires Dec. 31. The two sides are at odds over how much WSU should be compensated for physicians who work at the DMC and whether WSU physicians should be allowed to participate in business ventures that might compete with DMC interests. The beginnings of a physician exodus at WSU and DMC are under way, said Dr. John Flack, acting chief of medicine at the Detroit Medical Center and WSU. Dr. Paul Bozyk, president of the WSU/DMC Resident Council and chief resident in the Department of Medicine, said the stalemate is hurting recruitment efforts at a time of year when many graduate medical students are deciding where to begin their careers. Some departments are interviewing applicants while others are holding off on hiring until a contract agreement has been reached, he said.
