There is a dearth of data regarding the use of emergency interventions in dedicated emergency psychiatric service settings, and reliable data are needed. This article describes the frequency and duration of the use of seclusion and restraint for imminent or existing agitation, aggression, or violence in a dedicated emergency psychiatric service located within an academic university hospital and staffed by sufficient numbers of trained personnel.We performed a retrospective chart review of 6 months’ visits to a dedicated emergency psychiatric service.Men outnumbered women with a 1.6 ratio of visits. Of 2843 subjects, 425 (14.6%) received emergent medication for anxiety (n = 90), substance withdrawal (n = 28), or agitation (n = 290). Physical interventions were used in 3.4%; 96 (3.3%) were secluded, and 9 (0.3%) were restrained. The average duration of seclusion was (mean ± standard deviation) 58.7 ± 37.4 minutes and for restraint 63.2 ± 23.4 minutes. Each episode of seclusion or restraint required approximately 3 hours of staff time.The use of an intervention such as seclusion in >3% and restraint in 0.3% of patients represents the use of seclusion and restraint in a dedicated psychiatric emergency service with personnel trained to minimize the use of seclusion and restraint.
