The Michigan State Medical Society released a statement Wednesday saying Michigan faces a critical doctor shortage if the Detroit Medical Center and Wayne State University don\'t reach an agreement by the time their contract expires on Dec. 31. One of the issues at the root of a contract dispute between the DMC and WSU\'s School of Medicine is how doctors are compensated for the work they perform at the DMC. On Oct. 25, a national accreditation board threatened to shutter the medical residency programs the institutions jointly operate if an agreement isn\'t reached.
