Abstract: CADASIL is an arteriopathy caused by mutations of the Notch3 gene. White matter hyperintensities (WMH), lacunar lesions (LL), cerebral microhemorrhages (CM), brain atrophy and tissue microstructural changes are detected on MRI. Using an integrated multi-modal approach, we examined the relative impact of lesion burden and location of these MRI markers on cognitive impairment and disability. Multi-modal imaging was performed on 147 patients from a two-center cohort study. Volume of LL, WMH and number of CM was determined. Whole brain mean apparent diffusion coefficient (mean-ADC) and brain parenchymal fraction (BPF) were measured. In multivariate models accounting for lesion burden and location, volume of LL, mean-ADC, and BPF each had an independent influence on global cognitive function and disability. BPF explained the largest portion of the variation in cognitive and disability scores (35-38%). Brain atrophy has the strongest independent influence on clinical impairment in CADASIL when all MRI markers in the disease are considered together. The results suggest that the clinical impact of cerebral tissue loss plays a principal role in this genetic model of subcortical ischemic vascular dementia.

Abstract: Reducing and eliminating the use of restrictive practices, such as seclusion and restraint, is a national priority for Australia's mental health services. Whilst legislation, organization and practice changes have all contributed to a reduction in these practices, forensic mental health services continue to report high rates. This paper details the findings of research that examined the experiences of nurses working in the inpatient forensic mental health setting. The research aimed to (i) document the experiences of nurses working in the forensic mental health setting, (ii) articulate their perceived unique skill set to manage challenging patient behaviours, and (iii) determine how their experiences and skill set can inform practice changes to reduce the use of restrictive practices. Thirty-two nurses were recruited from one Australian forensic mental health service. Data were collected using semi-structured interviews and analysed using inductive content analysis. Four categories were identified that influenced practice experiences: (i) working in a challenging but interesting environment, (ii) specialty expertize, (iii) exposure to aggression and resilience as a protective factor, and (iv) the importance of effective teamwork and leadership. Forensic mental health care is complex, highly specialized, and often delivered in an unpredictable environment. Whilst high rates of restrictive practices may be linked to the unique characteristics of forensic patients, training, teamwork, and leadership are critical factors influencing their use in this setting. Nurses working in this area need to be educated and supported to work confidently and safely with this high-risk patient cohort.

Abstract: Increasingly, mental health nurses are expected to base their clinical practice on evidence based knowledge and many of the practice traditions that have passed between generations of nurses must now be examined within this scientific context. Since 2000, there has been an increasing debate on what is best practice for the administration of intramuscular injections particularly in relation to site selection, needle size and technique. Weight gain associated with second generation long acting antipsychotics influences the site and needle size for effective medication delivery. To determine intramuscular injecting practice choices made by nurses working in the mental health setting in 2006 compared to those made by a similar group of nurses in 2012. A descriptive cross sectional study conducted across two time points: 2006 (93 participants) and 2012 (245 participants) utilising the same questionnaire designed to measure nurses' intramuscular injecting practice choices. Data were analysed using SPSS version 20 package. Six statistically significant practice changes were recorded related to needle size, site selection and the use of the Z-tracking technique. A continued higher usage of the dorsogluteal site was also reported in 2012 contrary to the recommendations in the current research for the ventrogluteal site. Whilst some practice changes occurred, translation of research into evidenced based practice is challenging and definitive best practice in the administration of intramuscular injections remains unclear. Education and randomised controlled trials are needed to provide the evidence to ensure the delivery of safe and effective intramuscular injecting practice.

Abstract: Research on the influence of nursing staff composition and use of seclusion in the forensic mental health inpatient settings is sparse. Nursing staff composition refers to staffing levels, roles, gender ratio and skill mix of the ward teams. Internationally, the rates of seclusion in some forensic mental health inpatient settings have increased over the past 10 years despite global efforts to reduce and eliminate its use. To examine whether the use of seclusion in a forensic mental health inpatient setting can be attributed to staffing composition or to contextual factors such as day of the week, month or other clinical factors. Retrospective data collection was conducted using seclusion data, daily ward reports and staff rosters. Data were collected for all shifts in the hospital over a six-month period. Three staffing variables were identified as having an influence on the use of seclusion: the number of registered nurses on duty, the presence of the shift coordinator and having a lead nurse on shift. Senior nurse oversight and guidance are important factors in assisting staff to identify clinical deterioration and intervene early which may assist services reduce the use of seclusion. As staffing levels and composition are modifiable, the results of this study may assist nurse leaders to consider workforce improvements to reduce seclusion use.

Abstract: Approximately 210 patients are admitted each year to the Western Australian State Forensic Mental Health Service, and most present with psychotic illness, along with other physical and mental comorbidities. In 2010, a healthy lifestyle programme, which included a formal exercise programme coordinated by an exercise physiologist, was introduced at the service. A self-report questionnaire was developed to obtain feedback on the programme, and 56 patients completed the questionnaire during the 6-month evaluation period. As well as providing patients with access to regular physical activity, the programme also supports the recovery philosophy, where patients work in partnership with forensic mental health staff. Overall, patients reported that the programme assisted them to manage their psychiatric symptoms, as well as improving their level of fitness, confidence, and self-esteem. In addition, patients received education about the importance of regular exercise to their mental health, and the role exercise plays in preventing chronic illness and obesity. While the benefits of exercise on mental health outcomes for people with depression and anxiety are well established, this evaluation adds to the evidence that such programmes provide similar benefits to people who have a psychotic illness and are hospitalized in an acute secure setting.

Abstract: Seclusion and restraint use in health care is controversial. Such practices occur more frequently in forensic mental health settings than in acute mental health settings. There is growing interest in staff factors and their influence on such practices. The aim of this review was to identify and appraise studies that explore whether nursing staff characteristics, including age, gender, ethnicity and physical stature, influenced the use of these practices in forensic mental health settings. Eight electronic databases were searched to identify research studies published between 2010–2020. The search yielded 1085 articles, three of which fulfilled the inclusion criteria. There was no significant correlation between age, gender and experience and the tendency to use seclusion and restraint. No studies examined ethnicity, physical stature, seniority or role. The results demonstrate a paucity of research on nursing staff characteristics and their influence on seclusion and restraint in this setting. Such research may inform violence prevention strategies.

Abstract: The poor physical health of people with a severe mental illness is well documented and health professionals' attitudes, knowledge and skills are identified factors that impact on clients' access to care for their physical health needs. An evaluation was conducted to determine: (i) mental health nurses' attitudes and beliefs about providing physical health care and, (ii) the effect that participant demographics may have on attitudes to providing physical health care. It was hypothesized that workplace culture would have the largest effect on attitudes. Nurses at three health services completed the "Mental health nurses' attitude towards the physical health care of people with severe and enduring mental illness survey" developed by Robson and Haddad (2012). The 28-item survey measured: nurses' attitudes, confidence, identified barriers to providing care and attitudes towards clients smoking cigarettes. The findings demonstrated that workplace culture did influence the level of physical health care provided to clients. However, at the in idual level, nurses remain ided and uncertain where their responsibilities lie. Nursing leadership can have a significant impact on improving clients' physical health outcomes. Education is required to raise awareness of the need to reduce cigarette smoking in this client population.

Abstract: Mental illnesses constitute a major burden of disease in Aboriginal Australians and Torres Strait Islanders (hereafter Aboriginal Australians), who are also overrepresented in the prison system. A legacy of colonization compounds such prevalence, and is further exacerbated by the persistence of racial discrimination and insensitivity across many sectors, including health. This research completed in a Western Australian forensic mental health setting identifies non-Aboriginal health professionals' support needs to deliver high-quality, culturally-safe care to Aboriginal patients. Data were collected from health professionals using an online survey and 10 semistructured interviews. Survey and interview results found that ongoing education was needed for staff to provide culturally-safe care, where Aboriginal knowledge, beliefs, and values were respected. The findings also support previous research linking Aboriginal health providers to improved health outcomes for Aboriginal patients. In a colonized country, such as Australia, education programmes that critically reflect on power relations privileging white Anglo-Australian cultural dominance and subjugating Aboriginal knowledge, beliefs, and values are important to identify factors promoting or compromising the care of Aboriginal patients and developing a deeper understanding of 'cultural safety' and its clinical application. Organizational commitment is needed to translate the findings to support non-Aboriginal health professionals deliver high-quality care to Aboriginal patients that is respectful of cultural differences.

Abstract: Many countries now have national mental health policies and guidelines to decrease or eliminate the use of seclusion and restraint yet the use of Pro Re Nata (PRN) medications has received less practice evaluation. This research aimed to identify mental health nurses' attitudes towards the use of PRN medications with mental health consumers. Participants were working in forensic mental health and non-forensic acute mental health settings. The "Attitudes towards PRN medication use survey" was used and data were collected online. Data were analysed using the Statistical Package Social Sciences, Version 22.0. Practice differences between forensic and other acute mental health settings were identified related to the use of PRN medications to manage symptoms from nicotine, alcohol and other drug withdrawal. Differences related to the useage of comfort rooms and conducting comprehensive assessments of consumers' psychiatric symptoms were also detected. Qualitative findings highlighted the need for increased accountability for the prescribing and administration of PRN medications along with more nursing education/training to use alternative first line interventions. Nurses administering PRN medications should be vigilant regarding the indications for this practice to ensure they are facilitating the consumer's recovery by reducing the use of all forms of potentially restrictive practices in the hospital setting. The reasons for using PRN medications and PRN administration rates must be continually monitored to avoid practices such as high dose antipsychotics use and antipsychotic polypharmacy to ensure the efficacy of the consumers' management plans on their health care outcomes.
