We report information about restraint episodes on four psychiatric units with a total of 80 beds at the University of Rochester Medical Center during the three months before and the three months after the new rules were initiated. Throughout this period the units' occupancy rate remained between 95 and 100 percent. The medical center has four specialty units—a child and adolescent unit, a general adult unit, a unit for medically ill chemical-abusing patients, and a unit for neurogeriatric patients.
