Description: Psychiatric violence is a clinical problem as well as an occupational health hazard in public sector hospitals. A relatively small group of patients are responsible for the majority of violent events. Little is known about this habitually violent group. To identify risk factors predictive of habitual violence, a convenience sample of 50 habitually violent forensic male inpatients (HVP) was compared to a matched group of 35 inpatients who had not been violent in the hospital (NVP).

The Psychotic Inpatient Profile (PIP), the Brief Psychiatric Rating Scale (BPRS), and the Barnes Akathisia Scale were used to compare the clinical characteristics of the subjects in both groups. Nursing staff were asked to describe the behavioral precursors observed and the nursing interventions used with the HVP group.

Using logistic regression, membership in the HVP group was predicted by a high BPRS total score, high PIP subscale scores on psychotic disorganization and hostile belligerence, and low PIP scores on both paranoid projection and grandiosity. The HVPs were found to be younger, they had a length of stay (LOS) in excess of three years and they averaged 20 more assaults than the average inpatient. The model correctly classified 83.5% of the patients (sensitivity, 86%; specificity 80%). Violent criminal offense was not predictive of HVP group membership.

Nineteen of the HVPs were responsible for 31 weapon attacks in the hospital, including 11 repeat-weapon-users. The weapon-users averaged 15 more total assaults and almost 2.5 years longer LOS than non-weapon-using HVPs. HVPs who were assaultive more recently scored higher on the PIP hostile belligerence subscale, were younger by 3 years and had much shorter LOS.

The HVPs are described as loud, verbally abusive, threatening and hostile with idiosyncratic precursors including various fixations, bizarre mannerisms and sexually predatory behaviors. Staff report a narrow range of interventions including: establish rapport, redirect, confront, medicate and seclude and restrain.

The HVPs are a small, understudied subgroup of inpatients. Research providing for early identification and violence prevention is needed to assist nursing staff in managing this highly dangerous and psychiatrically-disabled group.
