Cyclical variations in psychiatric patient-to-staff assaults: preliminary inquiry

Assaults and nonpatient-induced injuries among psychiatric nursing staff in Bahrain

This retrospective study of incident reports at the psychiatric hospital in Bahrain was carried out to describe nursing staff injuries that were reported during 1992-1999. The average assault rate (4.4%) was much lower than that reported in Western countries. Of the 111 injuries, 44.0% occurred in wards assigned for patients with acute conditions, 27.5% in chronic condition wards, 5.5% in outpatients, and 22.9% in the community. Staff assaults by patients constituted 60.4% of all injuries, of which 64.2% occurred in the 1992-1995 period. The assault rate was highest in 1992 (6.8/100) and lowest in 1998 (1.1/100), while the rate for all injuries was highest in 1994 (12.0/100) and lowest in 1998 (3.3/100). Bahraini staff had higher assault (7.0/100) and total injury (14.8/100) rates than the non-Bahraini (5.5, 6.8/100, respectively). Odds ratios for assaults vs. nonpatient-induced injuries indicated that assaults were 2.3 times (95% CI: 1.05-4.95) more likely to occur in males, 5 times more likely (95% CI: 1.99-12.15) in non-Bahraini, 1.79 times more likely (95% CI: 0.81-3.95) in staff nurses, and 2.3 times more likely (95% CI: 1.05-5.01) in the evening. Suggestions for reducing assaults and nonpatient-induced injuries are discussed.

Risk factors for psychiatric inpatient assaults on staff

The risk of psychiatric patient assaults on staff members is increasing yearly, with resultant increases in employee victim suffering, medical expense, and lost productivity. Traditionally considered a clinician responsibility, the management of patient violence also has important administrative implications. This article presents a review of the risk factors associated with violence that includes the characteristics of patients who assault but adds the characteristics of employee victims of such assaults as well as contextual variables. Additional data from a two-year study of a peer-help crisis intervention program for employee victims of patient assaults are included. The mental health administrative implications of this approach are outlined.

Hospital downsizing and patients' assaults on staff

Although the downsizing and closing of state mental hospitals is occurring with increasing frequency nationwide, there appears to be only one case study of the clinical impacts of downsizing state hospitals. In this study, Snyder reported a four-fold increase in frequency of assaults on staff as the hospital census decreased. The present paper is a second case study of state hospital downsizing and closing in which the frequency of assaults on staff decreased by 63%. Possible explanations for the two differing outcomes are considered, and some general guidelines for the downsizing and closing of state hospitals are proposed.

Violence in hospitalized psychiatric patients: diurnal and seasonal patterns

The use of four-point physical restraints on a single occasion or repeatedly in psychiatric inpatients was followed prospectively during 1993 in Beer Sheva Mental Health Center. Mood-disordered patients had significantly more restraints per patient than did schizophrenic and schizoaffective patients. The monthly rates of restraints of mood-disordered and schizophrenic patients were found to be negatively correlated with the duration of the daily photoperiod, which was phase-advanced by a month. The findings suggest that seasonality (the duration of the daily photoperiod) should be taken into account in attempts to predict the potential dangerousness of psychiatric patients.
