Prediction of violence on a psychiatric intensive care unit

Abstract

The aim of the present study was to identify patients who were at particular risk of violent behaviour, over a period of one month in a psychiatric high dependency unit, and to examine whether particular patients could be identified at admission who would subsequently be violent. Medical records, and other documents for 52 inpatients were included. Demographic, historical and clinical data available at admission were noted. All violent incidents were recorded and classified. Seventeen of 52 patients committed physical violence, usually to the staff. Most incidents were carried out by a small number of individuals. Identifying the violent, using variables available at admission, was not possible. The ward admitted a group with a subsequent high rate of violence. Prediction within this high-risk group was not possible. Measures aimed at preventing violence on a local secure ward should apply to all patients and should not be targeted just at those that would appear to be the most likely to be violent.
