Epidemiology of violence and mental illness

Workplace violence prevention for nurses on-line course: Program development

BACKGROUND

Many entry-level and experienced healthcare professionals have not received training in workplace violence prevention strategies.

OBJECTIVE

This paper describes the development, content, and initial qualitative evaluation of an on-line course designed to give healthcare workers an opportunity to acquire free workplace violence prevention training while earning free continuing education units.

METHODS

A group of healthcare violence prevention researchers worked via email and face-to-face meetings to decide appropriate content for the course. Educational strategies used in the course include: text; video re-enactments of real-life workplace violence incidents; and videos of nurses discussing incidents of violence. Initial evaluation involved a focus group of nurses to discuss the course content and navigation.

RESULTS

The on-line course has thirteen units that take approximately 15 minutes each to complete. The focus group participants liked the ``resume-where-you-left-off'' technology that enables the user to complete any portion of the course, leave to do something, and return to the course where they left off. Participants viewed the ``Nurses' Voices'' videos as relevant illustrations of violence that nurses face in their workplaces.

CONCLUSIONS

The focus group participants considered the course to be an effective learning tool for people new to the profession and for those with seniority.

Retrospective review of trends in assaults and seclusion at an acute psychiatric ward over a 5-year period

In developing countries such as South Africa, not much is known about the prevalence of assaults and seclusion occurring in mental health wards over time. Here, we describe a 5-year trend in assaults and seclusions, stratified by gender, at Stikland Hospital, South Africa. A retrospective review of clinical records of patients admitted to the acute psychiatric admission wards at Stikland and involved in assault and secluded was undertaken between 1 January 2005 and 31 December 2010. Data on the number of patient and staff assaults as well as seclusions, gender, age, marital status, level of education, level of income, duration of hospital admission and primary psychiatric diagnosis were collected. Significantly (P < 0.01) more men than women engaged in patient assaults, while significantly (P < 0.01) more men were secluded than women. On a monthly basis, the number of gender-stratified patient assaults and seclusions significantly increased (P < 0.01) throughout the study period. In conclusion, we show here that gender had a significant effect on both patient assault and seclusion numbers, which increased towards the end of the study period. Monitoring of these events is therefore important to continuously improve quality of care.

Prevalence of mental disorder and related treatments in a local jail: a 20-month consecutive case study

Aims – To define the prevalence of mental disorder within an Italian local jail and to describe main psychiatric treatments provided. Methods – Cross-sectional study of consecutive male prisoners referred, over a twenty-month period, for a clinical psychiatric assessment, among population (N=990) of Casa circondariale “Torre del Gallo”, Pavia (I); clinical DSM-IV diagnostic assessment and retrospective analysis of provided psychiatric treatments (i.e. psychiatric visits and pharmacological prescriptions). Results – 191 men (19.3%) had one or more current mental disorders (excluding substance misuse), including 13 (1.3%) psychosis; 53 (5.4%) mood disorder; 24 (2.4%) anxiety disorder; 26 (2.6%) adjustment disorder; 40 (4.1%) personality disorder; 32 (3.2%) personality disorder plus mood disorder; 3 (0.3%) mental retardation. Substance- (N=89, 47%) and HIV-related (N=19, 10%) disorders comorbidity is recognised. Psychiatric visits are mainly provided to psychosis and personality disorder plus mood disorder subgroups. Off-label antipsychotics prescriptions are frequent. Conclusions – The prevalence of mental disorder in this population is higher than US and EU averages, and for particular diagnostic subgroups it could be underestimated. Psychiatric management in prison should be reorganized according to national and European health guidelines.

Ward safety perceived by ward managers in Britain, Germany and Switzerland: identifying factors that improve ability to deal with violence

Little is known about how safe nurses feel on psychiatric wards across different European countries. This paper is aim to evaluate how ward safety is perceived by ward managers in Great Britain, Germany and Switzerland. We replicated a Swiss questionnaire study in Germany and Britain, which asked ward managers on adult psychiatric wards to give details about their ward including data on the management of aggression, staffing levels, staff training, standards and type of restraint used, alarm devices, treatment and management of aggression and the existence and perceived efficacy of standards (protocols, guidelines). The British sample had by far the highest staffing levels per psychiatric bed, followed by Switzerland and Germany. The British ward managers by far perceived violence and aggression least as a problem on their wards, followed by Germany and then Switzerland. British ward managers are most satisfied with risk management and current practice dealing with violence. German managers were most likely to use fixation and most likely to have specific documentation for coercive measures. Swiss wards were most likely to use non-specific bedrooms for seclusion and carry alarm devices. British wards were far more likely to have protocols and training for the treatment and management of violence, followed by Switzerland and Germany. British ward managers by far perceived violence and aggression to be a small problem on their wards compared with Swiss and German ward managers. This was associated with the availability of control and restraint teams, regular training, clear protocols and a lesser degree risk assessments, but not staffing levels.

Co-occurring psychiatric and substance use disorders among male detainees in Italy

This paper presents data on the prevalence of co-occurring substance use and psychiatric disorders among newly imprisoned males in Italy. Interviewers conducted semi-structured clinical interviews with n=302 male detainees seven days after their admission to the prison of Perugia from August 2005 through July 2006. Over half of male detainees (54.3%) had either a substance use disorder or another psychiatric disorder. One of every five detainees (20.9%) had comorbid substance use and psychiatric disorders. Compared to detainees with psychiatric disorder only, substance use disorder only, or no disorder, detainees with comorbid substance use and psychiatric disorders were significantly more likely to have severe impairment in the areas of employment, substance abuse, family and social functioning, and psychiatric symptoms. Findings underscore the need for careful diagnostic screening at intake, access to treatment during detention, and an effective transition to services at the time of release.

Neurosteroid biosynthesis regulates sexually dimorphic fear and aggressive behavior in mice

The neurosteroid allopregnanolone is a potent positive allosteric modulator of GABA action at GABA(A) receptors. Allopregnanolone is synthesized in the brain from progesterone by the sequential action of 5alpha-reductase type I (5alpha-RI) and 3alpha-hydroxysteroid dehydrogenase (3alpha-HSD). 5alpha-RI and 3alpha-HSD are co-expressed in cortical, hippocampal, and olfactory bulb glutamatergic neurons and in output neurons of the amygdala, thalamus, cerebellum, and striatum. Neither 5alpha-RI nor 3alpha-HSD mRNAs is expressed in glial cells or in cortical or hippocampal GABAergic interneurons. It is likely that allopregnanolone synthesized in principal output neurons locally modulates GABA(A) receptor function by reaching GABA(A) receptor intracellular sites through lateral membrane diffusion. This review will focus on the behavioral effects of allopregnanolone on mouse models that are related to a sexually dimorphic regulation of brain allopregnanolone biosynthesis. Animal models of psychiatric disorders, including socially isolated male mice or mice that receive a long-term treatment with anabolic androgenic steroids (AAS), show abnormal behaviors such as altered fear responses and aggression. In these animal models, the cortico-limbic mRNA expression of 5alpha-RI is regulated in a sexually dimorphic manner. Hence, in selected glutamatergic pyramidal neurons of the cortex, CA3, and basolateral amygdala and in granular cells of the dentate gyrus, mRNA expression of 5alpha-RI is decreased, which results in a downregulation of allopregnanolone content. In contrast, 5alpha-RI mRNA expression fails to change in the striatum medium spiny neurons and in the reticular thalamic nucleus neurons, which are GABAergic.By manipulating allopregnanolone levels in glutamatergic cortico-limbic neurons in opposite directions to improve [using the potent selective brain steroidogenic stimulant (SBSS) S-norfluoxetine] or induce (using the potent 5alpha-RI inhibitor SKF 105,111) behavioral deficits, respectively, we have established the fundamental role of cortico-limbic allopregnanolone levels in the sexually dimorphic regulation of aggression and fear. By selectively targeting allopregnanolone downregulation in glutamatergic cortico-limbic neurons, i.e., by improving the response of GABA(A) receptors to GABA, new therapeutics would offer appropriate and safe management of psychiatric conditions, including impulsive aggression, irritability, irrational fear, anxiety, posttraumatic stress disorders, and depression.
