Incidence of violent behavior among patients in Psychiatric Intensive Care Units
European Journal of Psychiatry, 2016
Background and Objectives: Both psychiatric acute units and psychiatric intensive care units (PICUs) focus on acute treatment of behavioral disturbances such as violence and aggressive threats and acts. The aim of the present study is to describe the frequency of violent behavior; such as verbal or physical threats and physical attacks, among patients admitted to psychiatric intensive care unit (PICU). In addition the relationship between the episodes of threats and/or attacks in relation to time of the day, days of the week, and their seasonal variations was explored. Methods: All violent behavior was continuously assessed at the psychiatric emergency department. Data were collected during the period from May 2010 to May 2012. Results: Patients with only one hospitalization were less violent than those who have had two hospitalizations. There was a statistically significant difference in violence among patients without formal secondary education and those who have not formal educat...
Prediction of Violence on a Psychiatric Intensive Care Unit
Medicine, Science and the Law, 2000
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 like...
Violent incidents in a psychiatric intensive care unit
The British Journal of Psychiatry, 1994
A prospective study was undertaken of physical assaults over six months in a newly opened psychiatric intensive care unit. There were 58 admissions of 48 patients, and 37 assaults, three against other patients, and 34 against nursing and medical staff. Features which correlated with committing assault were a criminal record and previous drug abuse. Assaults occurred most frequently during the week, at times when staff were actively involved with the patients.

The aims of the present study were to investigate clinically relevant patient and environment-related predictive factors for threats and violent incidents the first three days in a PICU population based on evaluations done at admittance. Methods: In 2000 and 2001 all 118 consecutive patients were assessed at admittance to a Psychiatric Intensive Care Unit (PICU). Patient-related conditions as actuarial data from present admission, global clinical evaluations by physician at admittance and clinical nurses first day, a single rating with an observer rated scale scoring behaviours that predict short-term violence in psychiatric inpatients (The Brøset Violence Checklist (BVC)) at admittance, and environment-related conditions as use of segregation or not were related to the outcome measure Staff Observation Aggression Scale-Revised (SOAS-R). A multiple logistic regression analysis with SOAS-R as outcome variable was performed. Results: The global clinical evaluations and the BVC were effective and more suitable than actuarial data in predicting short-term aggression. The use of segregation reduced the number of SOAS-R incidents.
Predictors of violent behavior among acute psychiatric patients: Clinical study
Psychiatry and Clinical Neurosciences, 2008
Violence risk prediction is a priority issue for clinicians working with mentally disordered offenders. The aim of the present study was to determine violence risk factors in acute psychiatric inpatients. Methods: The study was conducted in a locked, short-term psychiatric inpatient unit and involved 374 patients consecutively admitted in a 1-year period. Sociodemographic and clinical data were obtained through a review of the medical records and patient interviews. Psychiatric symptoms at admission were assessed using the Brief Psychiatric Rating Scale (BPRS). Psychiatric diagnosis was formulated using the Structured Clinical Interview for DSM-IV. Past aggressive behavior was evaluated by interviewing patients, caregivers or other collateral informants. Aggressive behaviors in the ward were assessed using the Overt Aggression Scale. Patients who perpetrated verbal and against-object aggression or physical aggression in the month before admission were compared to non-aggressive patients, moreover, aggressive behavior during hospitalization and persistence of physical violence after admission were evaluated. Results: Violent behavior in the month before admission was associated with male sex, substance abuse and positive symptoms. The most significant risk factor for physical violence was a past history of physically aggressive behavior. The persistent physical assaultiveness before and during hospitalization was related to higher BPRS total scores and to more severe thought disturbances. Higher levels of hostility-suspiciousness BPRS scores predicted a change for the worse in violent behavior, from verbal to physical. Conclusion: A comprehensive evaluation of the history of past aggressive behavior and psychopathological variables has important implications for the prediction of violence in psychiatric settings.
The antecedents of violence and aggression within psychiatric in-patient settings
Acta Psychiatrica Scandinavica, 2012
antecedents of violence and aggression within psychiatric in-patient settings. Objective: To systematically review the types and proportions of antecedents of violence and aggression within psychiatric in-patient settings. Method: Empirical articles and reports with primary data pertaining to violence and aggression within adult psychiatric in-patient settings were retrieved. For each study, prospective antecedent data were extracted. The extracted antecedent data were thematically analysed, and all higher-level themes were meta-analysed using rate data. Results: Seventy-one studies met the inclusion criteria, from which 59 distinct antecedent themes were identified and organised into nine higher-level themes. The higher-level antecedent theme Ôstaff-patient interactionÕ was the most frequent type of antecedent overall, precipitating an estimated 39% of all violent ⁄ aggressive incidents. An examination of the staff-patient interaction themes revealed that limiting patients freedoms, by either placing some sort of restriction or denying a patient request, was the most frequent precursor of incidents, accounting for an estimated 25% of all antecedents. The higher-level themes Ôpatient behavioural cuesÕ and Ôno clear causeÕ also produced other large estimates and were attributed to 38% and 33% of incidents overall. Conclusion: This review underscores the influence that staff have in making in-patient psychiatric wards safe and efficacious environments.

Violence in acute psychiatric wards affects the safety of other patients and the effectiveness of treatment. However, there is a wide variation in reported rates of violence in acute psychiatric wards. To use meta-analysis to estimate the pooled rate of violence in published studies, and examine the characteristics of the participants, and aspects of the studies themselves that might explain the variation in the reported rates of violence (moderators). Systematic meta-analysis of studies published between January 1995 and December 2014, which reported rates of violence in acute psychiatric wards of general or psychiatric hospitals in high-income countries. Of the 23,972 inpatients described in 35 studies, the pooled proportion of patients who committed at least one act of violence was 17% (95% confidence interval (CI) 14-20%). Studies with higher proportions of male patients, involuntary patients, patients with schizophrenia and patients with alcohol use disorder reported higher rat...
Aggressive incidents on a psychiatric intensive care unit
Psychiatric Bulletin, 2008
Aims and MethodThis study looked at patient aggressive behaviour on an Irish psychiatric intensive care unit, and whether it was related to diagnosis, patient's insight and symptomatology. Each aggressive incident was recorded throughout the patient's stay using the Staff-Observed Aggression Scale.ResultsNinety-nine individuals were admitted to the unit during the study. We recorded 82 aggressive incidents, with most occurring during the daytime and on weekdays. There was no statistical difference in BPRS scores between the aggressive and non-aggressive groups. the aggressive patient group had a lower insight score than the non-aggressive group (P < 0.05) as measured on the Schedule of the Assessment of Insight. However, when gender and verbal aggression only were included in the analysis, the difference in insight was less significant (P=0.07).Clinical ImplicationsAggression is common on a psychiatric intensive care unit. Low levels of insight in patients may increase th...

Background Violence perpetrated by psychiatric inpatients is associated with modifiable factors. Current structured approaches to assess inpatient violence risk lack predictive validity and linkage to interventions. Methods Adult psychiatric inpatients on forensic and general wards in three psychiatric hospitals were recruited and followed up prospectively for 6 months. Information on modifiable (dynamic) risk factors were collected every 1–4 weeks, and baseline background factors. Data were transferred to a web-based monitoring system (FOxWeb) to calculate a total dynamic risk score. Outcomes were extracted from an incident-reporting system recording aggression and interpersonal violence. The association between total dynamic score and violent incidents was assessed by multilevel logistic regression and compared with dynamic score excluded. Results We recruited 89 patients and conducted 624 separate assessments (median 5/patient). Mean age was 39 (s.d. 12.5) years with 20% (n = 18)...
