Wayne State's School of Medicine Dean Robert Mentzer and DMC President and Chief Executive Officer Mike Duggan have agreed to resume formal negotiations in talks scheduled for Thursday and Friday. The national body that accredits graduate medical programs has given both sides an Oct. 1 deadline to report on the status of contract talks over how graduate medical programs operate. At issue are contracts that outline the financial and organizational arrangements for 69 residency programs. The two are operating under contracts worth $88 million a year. The contracts expired in March 2005 but were extended until Dec. 31.
