Background: There is a growing consensus to reduce the use of restrictive care practices in mental health settings to minimise the physical and psychological complications for patients. However, data regarding restrictive care practice use and factors contributing to variations in the proportion estimates has not previously been synthesised.Aims: This study aimed to synthesise evidence on (1) the pooled proportions of physical restraint, seclusion or chemical restraint in adult mental health inpatients and (2) sources of variability in these proportion estimates.Methods: Studies were identified from Scopus, MEDLINE, PsycINFO, Web of Science, Embase and CINAHL databases following the PRISMA 2020 guidelines. We conducted a meta‐analysis of studies published in English language from 1 January 2010 to 15 August 2022. Binomial data were pooled using a random effect model, with 95% confidence intervals. Meta‐regression was also computed to identify factors that may contribute to variations in the proportion estimates.Results: A total of 77 studies were included in this meta‐analysis. The pooled prevalence of physical restraint, seclusion and chemical restraint was 14.4%, 15.8% and 25.7%, respectively. Data were heterogeneous across studies (I2 > 99%). Reporting practices and geographical locations contributed to the variability in the reported estimates of restrictive care practices, with studies from Asian countries reporting higher proportions.Conclusion: There appear differences between geographical locations in the proportion of restrictive practices in mental health inpatients; however, this is complicated by how these prevalence data have been measured and defined. Consistency in the reporting of restrictive care practices in mental health is required to make valid comparisons between geographical regions, policy settings and practice innovations.Relevance to Clinical Practice: Efforts are needed to develop training programmes and policy changes to ensure consistency in defining and reporting of restrictive care practices in mental health facilities.Patient/Public Contribution: This is a systematic review that analysed data from previously published studies, and there was no patient/public contribution in this study.Protocol Registration: The protocol for this review has been registered to PROSPERO: CRD42022335167.

Purpose: Recovery-oriented practice (ROP) is growing internationally in mental health services. The study aimed to examine the perspectives of peer workers about ROP pre-implementation within one service. This is important to improve clinicians’ understandings of how service users feel and experience the organization’s culture, thereby improving recovery focus. Method: A focus group using semi-structured questions. The research design was a social constructivist exploratory study, utilizing a narrative approach. The data collected were qualitative, and analyzed for meaning units and categories in the data. Results: Eight participants were service user and carer peer workers. Peer workers considered their roles as educating clinicians, representing service users, aiding in cultural/systemic shifts in services, and as leaders. Peer workers add lived experience and can contribute to clinician uptake and fidelity of practice in ROP. Conclusion: The study contributes to the growing evidence that the inclusion of peer workers in mental health services is advantageous in the implementation of ROP to ensure a lived experience grounded perspective underpins practice and policy change.

Health services internationally are reconsidering whether current service delivery models are inclusive and responsive to lesbian, gay, bisexual, trans* and gender diverse, intersex, and/or queer (LGBTIQ+) identifying individuals. A survey was conducted to establish a baseline needs analysis, as part of an LGBTIQ+ workforce development program, on perceived staff knowledge and confidence in a multi-site public mental health service in Melbourne, Australia. The survey comprising multiple choice, 5-point Likert scale ratings, and short answer sections was administered to mental health staff attending training at their place of work. Workplaces included: community clinics, residential services, acute inpatient services, service development, and research departments. Perceptions of self-confidence and knowledge, and further support needs expressed, were examined through analyzing quantitative and qualitative responses in feedback following the education sessions. The sample comprised 85 respondents; the majority female (66%), with a good representation of staff across age brackets. While the majority of staff identified as heterosexual (68%), LGBTIQ+ individuals were represented. Though 64% of staff surveyed noted that opportunities exist in the workplace to discuss LGBTIQ+ issues, a desire to increase knowledge was expressed by 94% of staff. Staff attitudes, knowledge, confidence, and support needs should be carefully considered at organizational and leadership levels, to ensure health services foster LGBTIQ+ responsive service delivery models and practices.

Objective: We aimed to identify the baseline prevalence of cardiac dysfunction in patients commencing clozapine, assess adherence with echocardiographic monitoring recommendations, and evaluate the utility and cost of echocardiographic monitoring for the development of clozapine-associated myocarditis and cardiomyopathy. Methods: A retrospective longitudinal cohort study was undertaken of 159 consecutive patients from a major tertiary centre commencing clozapine in the period January 2002 to July 2009. Results: Some 73% of patients had a baseline study, and 11% had a six-month follow-up study. Nine patients had abnormal left ventricular function at baseline. Myocarditis was identified in three patients, with all cases occurring within the first month of treatment and suspected on clinical grounds before an echocardiogram was performed. One case of possible cardiomyopathy was identified. The cost of echocardiographic screening in the first year of treatment was estimated at $AUD 209,356 per case of cardiomyopathy detected. Conclusion: The prevalence of cardiac dysfunction in patients commencing clozapine is high, and there are challenges in adhering with the recommended protocol for monitoring. Routine echocardiography is not useful in the detection of clozapine-associated myocarditis. Although cardiomyopathy may be identified, it is rare and associated with significant cost. Recommendations for routine echocardiographic monitoring should be re-examined.

Families play an important role in relapse-prevention following a person's first psychotic episode. To evaluate an open-ended family group intervention within a public adult mental health service, semi-structured interviews were conducted with: (1) carers who continually attended; (2) carers who attended once only; (3) carers who never attended; (4) case managers and (5) early psychosis clinicians. Benefits to group participation included: reduced isolation, sense of collective experience, opportunity to feel heard, reduced stigma and shame, increased knowledge about mental illness, and enhanced skills in supporting the care recipient. Barriers included: competing family and work commitments, applicability to own experiences of caring, discomfort with social situations and revealing and hearing emotions, and a belief that experiences are private. While attending the group increased knowledge, the benefits most emphasized were in the social connection with other carers and sharing one's story in a safe and reassuring environment.

Objectives: To review the characteristics of all patients presenting with a first episode of psychosis between the ages of 16 and 65 years to an adult area mental health service. Methods: The early psychosis programme at St Vincent’s Hospital Melbourne treats all patients presenting in the early stages of psychosis between the ages of 16 and 65 years. A database was developed to capture the demographic and diagnostic characteristics of the group. The characteristics of those with an onset under 26 years were compared with those with a later onset. Results: A large proportion (55%) of those presenting with first episode psychosis presented after the age of 25 years. There were a higher number of cases of depression with psychotic features in the older onset patients (notably so for those over 40) and a trend towards greater metabolic morbidity. Discussion: Older patients presenting with a first episode of psychosis are relatively understudied but appear to have certain distinguishing qualities. Understanding the needs of these patients is important in tailoring optimal treatment packages and service responses.
