Staff injuries are on the rise at the Minnesota Security Hospital in St. Peter. A new report finds that injuries have gone up sharply as the number of permanent psychiatrists has dropped from six to just one. The hospital is the state’s largest facility for the mentally ill and dangerous. Through July 30th, the hospital recorded 40 employee injuries, up from 32 in all of 2011. The state says a change in restraints used on patients has also contributed. The facility several months ago switched from regular handcuffs on violent patients to Velcro restraints. Hospital employees quickly realized more employees were being hurt because it took longer to apply the Velcro restraints.
