Violence and aggression in psychiatric units.

OBJECTIVE: To help predict aggressive and violent behaviors, the frequency and types of these behaviors in acute psychiatric inpatient settings were examined, and potential interactions between staffing and patient mix and rates of the behaviors were explored. METHODS: Data on violent incidents were gathered prospectively in three adult acute psychiatric units in a general hospital and two units in a primary psychiatric hospital in Sydney, Australia. Staff recorded violent and aggressive incidents, which were ranked on an 8-level scale. They also completed weekly reports of staffing levels and patient mix. Poisson regression analysis was used to calculate relative rates, 95 percent confidence intervals, and p values. RESULTS: A total of 1,289 violent incidents were recorded over a seven-month period. Based on the scale, 58 percent of the incidents were serious. Seventy-eight percent were directed toward nursing staff. Complex relationships between staffing, patient mix, and violence were found. Relative risk increased with more nursing staff (of either sex), more nonnursing staff on planned leave, more patients known to instigate violence, a greater number of disoriented patients, more patients detained compulsorily, and more use of seclusion. The relative risk decreased with more young staff (under 30 years old), more nursing staff with unplanned absenteeism, more admissions, and more patients with substance abuse or physical illness. In total these factors accounted for 62 percent of the variance in violence. CONCLUSIONS: Violent incidents in psychiatric settings are a frequent and serious problem. Incidents appear to be underreported, and the seriousness of an incident does not guarantee it will be reported.

Repetitively violent patients in psychiatric units.

OBJECTIVE: Violent incidents in inpatient psychiatric settings were examined among a group of repeatedly violent patients to better understand the clinical and occupational health significance of repeated violence. METHODS: Data on violent incidents were collected prospectively over seven months in five psychiatric units in Sydney, Australia. Recidivist patients--those responsible for more than 20 incidents of violence or aggression--and nonrecidivist violent patients were compared in terms of the nature of the incidents, warning signs, and staff responses to violence. RESULTS: Of the 174 patients involved in violent incidents, 20 (12 percent) were recidivists. These patients accounted for 69 percent of the 752 violent incidents identified. Recidivists were significantly older than nonrecidivist patients. Compared with nonrecidivists, the men recidivists were more likely to have an organic brain syndrome, and the women recidivists were more likely to have a personality disorder. When a recidivist patient was violent, staff members' response was significantly less likely to include institutional mechanisms for dealing with violence, such as contacting occupational health and safety officers, completing injury notification forms, and notifying police. Violence occurred among recidivists despite their giving more warning signs than nonrecidivists, suggesting that recidivists' threats were not taken seriously by staff, perhaps reflecting demoralization in the face of repeated violence. CONCLUSIONS: Even though this study focused only on serious incidents and defined recidivism narrowly, it found that recidivism of violence and aggression among psychiatric patients was a serious problem. The relative lack of response by staff members to the violent acts of recidivist patients is of concern.

Lunar cycles and violent behaviour.

OBJECTIVE: It is commonly believed that the full moon exerts an influence on violence and aggression in psychiatric settings. The literature to date is contentious. This study used a robust methodology to examine the hypothesis that there was an increased frequency of violent and aggressive behaviour among hospitalised psychiatric clients at the time of the full moon. METHOD: Prospective data were collected in five inpatient psychiatric settings across the Northern Sydney Area Health Service. Morrison's hierarchy of violence and aggression was used to rate behaviour. Lunar phases were clearly defined and Poisson regression used to examine relationships between lunar phase and violence. Extraneous temporal variation was considered. RESULTS: No significant relationship was found between total violence and aggression or level of violence and aggression and any phase of the moon. CONCLUSION: Future research could profitably examine the implications of a belief in the lunar effect among health workers in the face of evidence that no relationship exists between violence, aggression and the lunar cycle.
