The purpose of this study is to describe the nursing practices recorded in reports of patient episodes of seclusion, with or without restraints, in a specialized psychiatric facility in Quebec. The reports for all adult patients secluded (n = 4863) in a psychiatric unit between April 1, 2007 and March 31, 2009, were examined. Descriptive analyses were performed. The main reasons for seclusion were agitation, disorganization, and aggressive behaviour. The alternative methods that were attempted included stimulus reduction, extra medication, and working with the patient to find a solution. Few families were notified about their relation's seclusion. More hours of seclusion were reported in the evening and at night. Our results are comparable to those obtained by other investigators. Some of the variables have not been the subject of much research: for example, health conditions during seclusion with or without restraint and partnerships with family members. Our findings also suggest that, in their analyses, studies should differentiate between cognitive-impairment and adult-psychiatry units as well as long-term seclusion and short-term seclusion. The information reported by the nurse makes no distinction between short-stay and long-stay adult psychiatric units. Only one psychiatric facility was investigated in this study, precluding generalization.
