Inpatient seclusion: description and causes.

A total of 114 (31%) of 370 acute admissions to an inpatient unit over a one-year interval had at least one episode of seclusion or restraint. Four variables were significant predictors of seclusion and restraint. They were young age, diagnosis of borderline personality disorder, and two scores (irritability and total assets) on the Nurses Observation Scale for Inpatient Evaluation (NOSIE). More than 81% of the predictions were correct (Kappa = .37, p < .001). The four predictive variables were used to predict seclusion and restraint in a new sample of 80 patients. More than 79% of the predictions were correct (Kappa = .40, p < .001).
