Effects of Ending the Use of Seclusion and Mechanical Restraint in the Pennsylvania State Hospital System, 2011-2020.

Abstract

The Pennsylvania State Hospital System's use of containment procedures has been studied for >30 years. This prospective study assessed the effects of ending the use of seclusion and mechanical restraint in the system's six civil hospitals and two forensic centers from 2011 to 2020. The study examined the effect of this change on key safety measures: physical restraint, assaults, aggression, and self-injurious behavior. In total, 68,153 incidents, including 9,518 episodes of physical restraint involving 1,811 individuals, were entered into a database along with patients' demographic and diagnostic information. All data were calculated per 1,000 days to control for census changes. During the study, mechanical restraint was used 128 times and seclusion four times. Physical restraint use decreased from a high of 2.62 uses per 1,000 days in 2013 to 2.02 in 2020. The average length of time a person was held in physical restraint was reduced by 64%, from 6.6 minutes in 2011 to 2.4 minutes in 2020 (p<0.001). All safety measures improved or were unchanged. Use of unscheduled medication did not change. The hospital system safely ended the use of mechanical restraint and seclusion by using a recovery approach and by following the six core strategies for seclusion and restraint reduction.
