2023 Cardiac Society of Australia and New Zealand Expert Position Statement on Catheter and Surgical Ablation for Atrial Fibrillation.

Catheter ablation for atrial fibrillation (AF) has increased exponentially in many developed countries, including Australia and New Zealand. This Expert Position Statement on Catheter and Surgical Ablation for Atrial Fibrillation from the Cardiac Society of Australia and New Zealand (CSANZ) recognises healthcare factors, expertise and expenditure relevant to the Australian and New Zealand healthcare environments including considerations of potential implications for First Nations Peoples. The statement is cognisant of international advice but tailored to local conditions and populations, and is intended to be used by electrophysiologists, cardiologists and general physicians across all disciplines caring for patients with AF. They are also intended to provide guidance to healthcare facilities seeking to establish or maintain catheter ablation for AF.

Supporting equitable care of patients transferred from police watch-houses to the emergency department: A qualitative study of the perspectives of emergency doctors.

OBJECTIVE: People detained in short-term police custody often have complex health conditions that may necessitate emergency care, yet little is known about their management in EDs. The present study aimed to understand ED doctors' experiences and perceptions regarding the appropriateness and management of detainee transfers from police watch-houses to the EDs. METHODS: A qualitative descriptive study, using semi-structured interviews undertaken with ED doctors working in five purposively sampled EDs across Queensland, Australia. Data were analysed using inductive content analysis. RESULTS: Fifteen ED specialists and trainees participated. Participants reported that their overarching approach was to provide equitable care for watch-house detainees, as they would for any patient. This equitable approach needed to be responsive to complicating factors common to this population, including presence of police guards; restraints; complexity (physical/mental/social) of presentation; reliance on police to transport; ED doctors' often limited understanding of the watch-house environment; justice processes and uncertain legal disposition; communication with the watch-house; and detainees misreporting symptoms. Thresholds for assessment and treatment of detainees were contextualised to the needs of the patient, ED environment, and imperatives of other relevant agencies (e.g. police). Participants often relied on existing strategies to deliver quality care despite challenges, but also identified a need for additional strategies, including education for ED staff; improved communication with watch-houses; standardised paperwork; extended models of watch-house healthcare; and integrated medical records. CONCLUSIONS: Providing equitable healthcare to patients transported from watch-houses to the EDs is challenging but essential. Numerous opportunities exist to enhance the delivery of optimal care for this underserved population.

Long-Term Safety and Efficacy of Transcatheter Microwave and Radiofrequency Denervation in a Chronic Ovine Model.

BACKGROUND: Transcatheter renal denervation (RDN) has had inconsistent efficacy and concerns for durability of denervation. We aimed to investigate long-term safety and efficacy of transcatheter microwave RDN in vivo in normotensive sheep in comparison to conventional radiofrequency ablation. METHODS AND RESULTS: Sheep underwent bilateral RDN, receiving 1 to 2 microwave ablations (maximum power of 80-120 W for 240 s-480 s) and 12 to 16 radiofrequency ablations (180 s-240 s) in the main renal artery in a paired fashion, alternating the side of treatment, euthanized at 2 weeks (acute N=15) or 5.5 months (chronic N=15), and compared with undenervated controls (N=4). Microwave RDN produced substantial circumferential perivascular injury compared with radiofrequency at both 2 weeks [area 239.8 (interquartile range [IQR] 152.0-343.4) mm2 versus 50.1 (IQR, 32.0-74.6) mm2, P <0.001; depth 16.4 (IQR, 13.9-18.9) mm versus 7.5 (IQR, 6.0-8.9) mm P <0.001] and 5.5 months [area 20.0 (IQR, 3.4-31.8) mm2 versus 5.0 (IQR, 1.4-7.3) mm2, P=0.025; depth 5.9 (IQR, 1.9-8.8) mm versus 3.1 (IQR, 1.2-4.1) mm, P=0.005] using mixed models. Renal denervation resulted in significant long-term reductions in viability of renal sympathetic nerves [58.9% reduction with microwave (P=0.01) and 45% reduction with radiofrequency (P=0.017)] and median cortical norepinephrine levels [71% reduction with microwave (P <0.001) and 72.9% reduction with radiofrequency (P <0.001)] at 5.5 months compared with undenervated controls. CONCLUSIONS: Transcatheter microwave RDN produces deep circumferential perivascular ablations without significant arterial injury to provide effective and durable RDN at 5.5 months compared with radiofrequency RDN.

Clinician-Created Video Education for Patients With AF: A Randomized Clinical Trial.

Importance: Patient education is a critical aspect of atrial fibrillation (AF) management. However, there is limited time to provide effective patient education during routine care, and resources available online are of variable quality. Objective: To determine whether clinician-led creation of video-based AF education is feasible and improves knowledge of AF. Design, Setting, and Participants: This single-center randomized clinical trial was conducted between 2020 and 2022. Outcomes were assessed prior to their clinic visit and 2 and 90 days after the visit by blinded assessors. Participants included adults with AF and congestive heart failure, hypertension, age at least 75 years (doubled), diabetes, prior stroke or transient ischemic attack or thromboembolism (doubled), vascular disease, age 65 to 74 years, and sex category scores of 1 or greater presenting for routine care at publicly funded outpatient cardiology clinics within a tertiary teaching hospital. Individuals too unwell to participate or with limited English were excluded. Data were assessed as intention to treat and analyzed from December 2022 to October 2023. Intervention: Intervention participants viewed a series of 4 videos designed and narrated by clinicians that aimed to improve understanding of AF pathophysiology, clinical presentation, diagnosis, and management. After viewing the videos, participants received weekly email links to review the videos. The control group received usual care. Main Outcomes and Measures: The prospectively selected primary outcome was AF knowledge at 90 days, measured by the validated Jessa Atrial Fibrillation Knowledge Questionnaire (JAFKQ). Results: Among 657 individuals screened, 208 adults with AF were randomized (mean [SD] age, 65.0 [12.2] years; 133 [65.2%] male) and included in analysis. Participants were randomized 1-to-1, with 104 participants in the control group and 104 participants in the video intervention group. At 90 days after the baseline clinic visit, intervention participants were more likely to correctly answer JAFKQ questions than control participants (odds ratio [OR], 1.23 [95% CI, 1.01-1.49]). The difference was greater in participants who remotely accessed videos on 3 or more occasions during the study (OR, 1.46 [95% CI, 1.14-1.88]). Conclusions and Relevance: In this randomized clinical trial of patients with AF, remotely delivered, clinician-created video education improved medium-term AF knowledge beyond usual care of standard in-clinic education. The improvement demonstrated in this study provides support for the implementation of clinician-created educational resources across the care continuum. Further work is needed to assess for impact on clinical outcomes. Trial Registration: anzctr.org.au Identifier: ANZCTRN12620000729921.

Evaluation of the Panbio™ COVID-19 IgG rapid test device performance.

Background: The Panbio™ COVID-19 IgG Rapid Test Device ("Panbio™") detects IgG antibodies against the SARS-CoV-2 spike protein from viral infection or vaccination. Objectives: To determine the diagnostic sensitivity and specificity of the Panbio™ professional use test, using fingerstick whole blood and venous plasma. Study design: Fingerstick whole blood and venous plasma from each participant were tested with Panbio™ and compared against the SARS-CoV-2 IgG II assay on the Abbott Architect™ platform (Europe) or the equivalent AdviseDx SARS-CoV-2 IgG II Abbott Alinity i™ platform (US). 447 evaluable participants were enrolled across 6 US and 9 European clinical centers. Results: For unvaccinated participants with PCR-confirmed infection ≥21 days post-symptom onset, the Panbio™ sensitivity with fingerstick whole blood was 92.6 % (95 % CI: 85.9, 96.7), and the specificity was 97.0 % (95 % CI: 93.1, 99.0). For venous plasma, the sensitivity was 90.0 % (95 % CI: 79.5, 96.2) for participants with PCR-confirmed infection and symptom onset 22-180 days ago; the specificity was 96.3 % (92.2, 98.6). For vaccinated participants, the sensitivity was 98.4 % (95 % CI: 91.2, 100.0) for fingerstick whole blood and 96.7 % (95 % CI: 88.7, 99.6) for venous plasma. Conclusion: The Panbio™ test had high sensitivity and specificity for detecting IgG against the SARS-CoV-2 spike protein.

Police perspectives on the economic considerations of providing healthcare in short-term custodial settings in Australia.

Providing appropriate healthcare to people in short-term police custody settings (i.e. watch-houses) is challenging due to the complexity of detainee health needs and the limitations of the custodial environment. However, little is known about how detainee healthcare is managed in Australia, including economic considerations. This study had two aims: (1) to understand police perspectives on the costs associated with the delivery of healthcare to watch-house detainees in Queensland, Australia and (2) to scope the applicability of the Prison Healthcare Expenditure Reporting Checklist (PHERC) tool for the Australian watch-house context. The study employed an exploratory qualitative descriptive approach. A purposive sample comprised 16 watch-house staff from six regions in Queensland, Australia, interviewed between April and November 2021. A key finding was that police viewed healthcare expenditure as a major, but largely unavoidable cost for Australian watch-houses. Participants reported that direct expenditure comprised mostly of in-house healthcare services (of which there were a variety of models), but also costs of medication and health-related consumables. Indirect costs included costs of escorting and guarding detainees requiring transfer to hospital for health assessment and treatment. Participants reported that the PHERC was not applicable to the Australian watch-house context. Future research should explore the cost-effectiveness of different watch-house healthcare delivery models and how best to measure this.

Why do nurses seek employment in forensic mental health and what are their first impressions of the clinical environment? A mixed methods study.

AIM: The aim of the study was to investigate why registered nurses seek forensic mental health employment and explore their initial impressions of this setting. DESIGN: Explanatory sequential mixed methods. METHODS: Registered nurses employed in a forensic mental health hospital completed an online survey about their reasons for seeking work in forensic mental health and their transition into the setting. To fully explore findings, semi-structured interviews were conducted with a sub-group of survey respondents. Descriptive statistics were used to analyse survey data, and thematic analysis was used to analyse the interviews. RESULTS: Sixty-nine respondents completed the survey, and 11 interviews were conducted. Prior interest in forensic mental health and encouragement from hospital staff were considered important influences in seeking forensic mental health employment. New knowledge, changes in clinical responsibility, exposure to patients' background offences and security processes overwhelmed some participants initially. However, participants reported that the initial challenges of their transition revealed opportunities to develop genuine connections with patients. CONCLUSION: This study provides a new understanding of the reasons why nurses seek employment in forensic mental health and the challenges and opportunities experienced when first working in this setting. Such professional and personal elements need to be considered by organizations to strengthen recruitment strategies and support future nurses' transition into forensic mental health settings. IMPACT: This study provides new knowledge about recruiting and supporting nurses' transition into forensic mental health employment. As such, it informs policymakers, clinical services and managers about strategies needed to attract and retain this workforce. PATIENT OR PUBLIC CONTRIBUTION: No public or patient involvement.

CRISPR-based large-scale modeling of loss-of-function mutations to investigate mechanisms of stress resistance in cancer.

Dissecting mechanisms driving subclone expansion in primary cancers has been challenging. Here, we present a protocol to systematically disrupt entire gene networks and assess the functional impact of this perturbation on cancer cell fitness. By combining arrayed CRISPR libraries and high-content microscopy, we describe steps to identify classes of genes whose inactivation promotes resistance to environmental challenges faced by cancer cells during tumor growth or upon therapy. A proof-of-principle interrogation of the epigenetic regulatory network is described. For complete details on the use and execution of this protocol, please refer to Loukas et al. (2022).1.

A Prospective, Multicentre Randomised Controlled Trial Comparing Catheter Ablation Versus Antiarrhythmic Drugs in Patients With Structural Heart Disease Related Ventricular Tachycardia: The CAAD-VT Trial Protocol.

IMPORTANCE: Randomised trials have shown that catheter ablation (CA) is superior to medical therapy for ventricular tachycardia (VT) largely in patients with ischaemic heart disease. Whether this translates to patients with all forms and stages of structural heart disease (SHD-e.g., non-ischaemic heart disease) is unclear. This trial will help clarify whether catheter ablation offers superior outcomes compared to medical therapy for VT in all patients with SHD. OBJECTIVE: To determine in patients with SHD and spontaneous or inducible VT, if catheter ablation is more efficacious than medical therapy in control of VT during follow-up. DESIGN: Randomised controlled trial including 162 patients, with an allocation ratio of 1:1, stratified by left ventricular ejection fraction (LVEF) and geographical region of site, with a median follow-up of 18-months and a minimum follow-up of 1 year. SETTING: Multicentre study performed in centres across Australia. PARTICIPANTS: Structural heart disease patients with sustained VT or inducible VT (n=162). INTERVENTION: Early treatment, within 30 days of randomisation, with catheter ablation (intervention) or initial treatment with antiarrhythmic drugs only (control). MAIN OUTCOMES, MEASURES, AND RESULTS: Primary endpoint will be a composite of recurrent VT, VT storm (≥3 VT episodes in 24 hrs or incessant VT), or death. Secondary outcomes will include each of the individual primary endpoints, VT burden (number of VT episodes in the 6 months preceding intervention compared to the 6 months after intervention), cardiovascular hospitalisation, mortality (including all-cause mortality, cardiac death, and non-cardiac death) and LVEF (assessed by transthoracic echocardiography from baseline to 6-, 12-, 24- and 36-months post intervention). CONCLUSIONS AND RELEVANCE: The Catheter Ablation versus Anti-arrhythmic Drugs for Ventricular Tachycardia (CAAD-VT) trial will help determine whether catheter ablation is superior to antiarrhythmic drug therapy alone, in patients with SHD-related VT.

The experience of nurses moving into forensic mental health employment: A qualitative study.

While forensic mental health has seen considerable growth over the last two decades, little is known about the experience of registered nurses working in these environments. This study used a qualitative descriptive approach and interviewed 11 registered nurses to explore the interpersonal experiences of transition into a forensic mental health hospital. The data revealed three themes. 'Observing what's safe' examined nurses' ability to maintain safety in the context of inconsistent practices among colleagues. 'Navigating cliques and divisions' focused on nurses' sense of belonging and adapting to professional and personal groups. Finally, 'gaining management support' reflected nurses' experiences of engagement with management. This study provides new insight into nurses' experience of adapting to employment in forensic mental health settings and highlights the importance of positive support strategies for workplace transition.

Open Versus Closed Group Treatment of Men with a History of Sexual Offenses.

Treatment programs for people with histories of sexual violence form a critical part of criminal justice service rehabilitation. Completion of these programs is often a precondition of release. Meta-analytic reviews suggest moderate benefit is associated with treatment completion, although effect sizes vary. This study examined whether commencement of open versus closed group programs was associated with treatment completion and recidivism. Participants were 426 adult men who commenced treatment between April 1, 2014, and December 31, 2017. Participants were followed-up until June 30, 2018. Programs varied by type (open versus closed), location (in-custody versus in-community) and intensity (moderate versus high). No significant differences were observed between open and closed programs for treatment completion but men who were treated in-custody were more likely to complete treatment when compared to those men who commenced treatment in the community. No significant differences were observed between open and closed programs for sexual or for any recidivism.

Impact of sex on clinical, procedural characteristics and outcomes of catheter ablation for ventricular arrhythmias according to underlying heart disease.

BACKGROUND: Women are under-represented in many key studies and trials examining outcomes of catheter ablation (CA) for ventricular arrhythmias (VA). We compared characteristics between men and women undergoing their first catheter ablation for VA at a single centre over 10 years. METHODS: The clinical, procedural characteristics and outcomes of 287 consecutive patients (male = 182, female = 105), undergoing their first CA at our centre over 10 years were compared according to sex and underlying heart disease. RESULTS: In the ablation population, women were younger, had fewer co-morbidities, were less likely to have ischemic cardiomyopathy (ICM) and VA storm and were more likely to have idiopathic VA and premature ventricular complexes as the indication for ablation (P < 0.05 for all). Amongst idiopathic and non-ischemic cardiomyopathy (NICM) subgroups, baseline characteristics were similar; amongst ICM, women were younger and had higher numbers of drug failure pre-ablation (P = 0.05). Women were similar to men in all procedural characteristics, acute procedural success and complications, regardless of underlying heart disease. At median follow-up of 666 days, VA-free survival, overall mortality and survival free of death or transplant were comparable in both groups. Sex was not a predictor of these outcomes, after accounting for clinical and procedural characteristics. CONCLUSION: Women represented 36% of the real-world population at our centre referred for CA of VA. There are key differences in clinical features of women versus men referred for VA ablation. Despite these differences, VA ablation in women can be accomplished with similar success and complication rates to men, regardless of underlying heart disease.

Early Catheter Ablation Versus Initial Medical Therapy for Ventricular Tachycardia Storm.

BACKGROUND: Ventricular tachycardia (VT) storm is associated with significantly increased morbidity, mortality, and exponential healthcare utilization. Although catheter ablation (CA) may be curative, there are limited data directly comparing outcomes of early CA with initial medical therapy. METHODS: We compared outcomes of patients presenting with VT storm treated with initial CA versus those treated with initial medical therapy during their first storm presentation in an observational study. Retrospective data from the host institution from January 2014 to April 2020 of 129 patients with their first VT storm presentation were analyzed (58 underwent initial CA, 71 underwent treatment with initial medical therapy). Outcomes were compared in follow-up. RESULTS: Median time to initial CA was 6 days. Over a median follow-up of 702 days, patients who underwent initial CA compared with those treated with initial medical therapy had significantly less: (i) VA recurrence (43% versus 92%; P=0.002); (ii) VT storm recurrence (28% versus 73%; P<0.001); (iii) composite end point of death, heart transplant, VT storm recurrence, and VT-related hospitalization (47% versus 89%; P=0.002); (iv) iatrogenic complications (at 12 months: 17% versus 45%; P<0.001); (v) cardiovascular-related hospitalizations (50% versus 89%; P=0.01); (vi) total number of hospitalizations (median 1 versus 4; P<0.001); and (vi) cumulative days in hospital (median 0.5 versus 18; P<0.001). There were no intraprocedural deaths in patients treated with early CA. CONCLUSION: In an observational setting in which patients presenting with storm, early CA appears superior to initial medical therapy in terms of VT recurrence, storm recurrence, iatrogenic complications, cardiovascular hospitalizations, and cumulative days in hospital in follow-up.

The Role of Contemporary Wearable and Handheld Devices in the Diagnosis and Management of Cardiac Arrhythmias.

Cardiac arrhythmias are associated with significant morbidity, mortality and economic burden on the health care system. Detection and surveillance of cardiac arrhythmias using medical grade non-invasive methods (electrocardiogram, Holter monitoring) is the accepted standard of care. Whilst their accuracy is excellent, significant limitations remain in terms of accessibility, ease of use, cost, and a suboptimal diagnostic yield (up to ∼50%) which is critically dependent on the duration of monitoring. Contemporary wearable and handheld devices that utilise photoplethysmography and the electrocardiogram present a novel opportunity for remote screening and diagnosis of arrhythmias. They have significant advantages in terms of accessibility and availability with the potential of enhancing the diagnostic yield of episodic arrhythmias. However, there is limited data on the accuracy and diagnostic utility of these devices and their role in therapeutic decision making in clinical practice remains unclear. Evidence is mounting that they may be useful in screening for atrial fibrillation, and anecdotally, for the diagnosis of other brady and tachyarrhythmias. Recently, there has been an explosion of patient uptake of such devices for self-monitoring of arrhythmias. Frequently, the clinician is presented such information for review and comment, which may influence clinical decisions about treatment. Further studies are needed before incorporation of such technologies in routine clinical practice, given the lack of systematic data on their accuracy and utility. Moreover, challenges with regulation of quality standards and privacy remain. This state-of-the-art review summarises the role of novel ambulatory, commercially available, heart rhythm monitors in the diagnosis and management of cardiac arrhythmias and their expanding role in the diagnostic and therapeutic paradigm in cardiology.

Catheter Ablation for Ventricular Tachycardia in Ischaemic Versus Non-Ischaemic Cardiomyopathy: A Systematic Review and Meta-Analysis.

BACKGROUND: There are differences in substrate and ablation approaches for ventricular tachycardia (VT) in ischaemic (ICM) and non-ischaemic cardiomyopathy (NICM). OBJECTIVE: To perform a systematic review and meta-analysis comparing clinical and procedural characteristics/outcomes of VT ablation in ICM versus NICM. METHODS: Electronic databases were searched for comparative studies reporting outcomes of VT ablation in patients with ICM and NICM. Primary outcomes were acute procedural success, VT recurrence and long-term mortality. Meta-analyses were performed using random-effects modelling. RESULTS: Thirty-one (31) studies (7,473 patients; 4,418 ICM and 3,055 NICM) were included. Patients with ICM were significantly older (67.0 vs 55.3 yrs), more commonly male (89% vs 79%), had lower left ventricular ejection fraction (29% vs 38%) were less likely to undergo epicardial access (11% vs 36%) and were more likely to require haemodynamic support during ablation (relative risk [RR] 1.30; 95% CI 1.01-1.69). Acute procedural success (i.e. non-inducibility of VT) was higher in the ICM cohort (RR 1.10, 95% CI 1.05-1.15). Recurrence of VT at follow-up was significantly lower in the ICM cohort (RR 0.77; 95% CI 0.70-0.84). Peri-procedural mortality, incidence of procedural complications and long-term mortality were not significantly different between the cohorts. CONCLUSIONS: NICM and ICM patients undergoing VT ablation are fundamentally different in their clinical characteristics, ablation approaches, acute procedural outcomes and likelihood of VA recurrence. VT ablation in NICM has a lower likelihood of procedural success with increased risk of VA recurrence, consistent with known challenging arrhythmia substrate.

Coordinating Health Care With Artificial Intelligence-Supported Technology for Patients With Atrial Fibrillation: Protocol for a Randomized Controlled Trial.

BACKGROUND: Atrial fibrillation (AF) is an increasingly common chronic health condition for which integrated care that is multidisciplinary and patient-centric is recommended yet challenging to implement. OBJECTIVE: The aim of Coordinating Health Care With Artificial Intelligence-Supported Technology in AF is to evaluate the feasibility and potential efficacy of a digital intervention (AF-Support) comprising preprogrammed automated telephone calls (artificial intelligence conversational technology), SMS text messages, and emails, as well as an educational website, to support patients with AF in self-managing their condition and coordinate primary and secondary care follow-up. METHODS: Coordinating Health Care With Artificial Intelligence-Supported Technology in AF is a 6-month randomized controlled trial of adult patients with AF (n=385), who will be allocated in a ratio of 4:1 to AF-Support or usual care, with postintervention semistructured interviews. The primary outcome is AF-related quality of life, and the secondary outcomes include cardiovascular risk factors, outcomes, and health care use. The 4:1 allocation design enables a detailed examination of the feasibility, uptake, and process of the implementation of AF-Support. Participants with new or ongoing AF will be recruited from hospitals and specialist-led clinics in Sydney, New South Wales, Australia. AF-Support has been co-designed with clinicians, researchers, information technologists, and patients. Automated telephone calls will occur 7 times, with the first call triggered to commence 24 to 48 hours after enrollment. Calls follow a standard flow but are customized to vary depending on patients' responses. Calls assess AF symptoms, and participants' responses will trigger different system responses based on prespecified protocols, including the identification of red flags requiring escalation. Randomization will be performed electronically, and allocation concealment will be ensured. Because of the nature of this trial, only outcome assessors and data analysts will be blinded. For the primary outcome, groups will be compared using an analysis of covariance adjusted for corresponding baseline values. Randomized trial data analysis will be performed according to the intention-to-treat principle, and qualitative data will be thematically analyzed. RESULTS: Ethics approval was granted by the Western Sydney Local Health District Human Ethics Research Committee, and recruitment started in December 2020. As of December 2021, a total of 103 patients had been recruited. CONCLUSIONS: This study will address the gap in knowledge with respect to the role of postdischarge digital care models for supporting patients with AF.

Exploring the victim offender overlap among people with an intellectual disability.

BACKGROUND: While there is growing international evidence pointing to the increased risks of crime perpetration and victimisation for some people with an intellectual disability, the overlap between offending and victimisation (the victim-offender overlap) remains unclear. METHOD: This study utilised a data linkage methodology of 2600 people with an intellectual disability, exploring their contacts with public mental health services and the police in Victoria, Australia. RESULTS: Victim-offenders accounted for a small proportion of the sample (n = 148, 5.7%). The victim-offender overlap was evident for both violent and nonviolent nonsexual crimes, particularly for theft, burglary, and threat-related crimes. Key differences were also noted between males and females. CONCLUSIONS: People with an intellectual disability who are both victim and offenders comprise a small but particularly complex justice-involved population. Future research should explore the victim offender overlap for males and females separately, as well as any additional risks and vulnerabilities associated with specific mental health diagnoses.

A critical review of research into mental health consumers' perspectives on their physical health: Is there an absence of consumers in the design, conduct, analysis and reporting of this research?

We conducted a critical review, using systematic methods, of the literature examining mental health consumer perspectives on their physical and mental health in academic research published between 2005 and 2021. This review examined the inclusion, extent, type and centrality of consumer perspectives regarding their mental and physical health. The search produced 1,865 papers from which 116 met the inclusion criteria. Studies predominantly focused on consumers' individual experiences of their physical and mental health, including but not limited to their understandings and experiences of medication and associated risk factors. They also captured some social aspects of mental health consumers' physical health, including factors that impacted individual agency, stigma, and social and interpersonal factors. Structural factors affecting physical and mental health, such as accessibility of services and financial constraints, were also identified. The review revealed that in comparison to clinician perspectives, the direct representation of consumer perspectives was lacking. Similarly, while clinician and carer perspectives on structural factors were investigated, the consumer perspective in this area was missing. The review also found few genuine codesigned or coproduced research studies. To better identify and respond to the health needs as prioritized by consumers, this paper argues it is imperative that future studies prioritize codesigned and coproduced research. It is argued that a focus on "services as provided" rather than "services as received" has contributed to a lack of progress in addressing the life expectancy gap for consumers. It is recommended that journals, ethics committees and research policy organizations develop guidelines and standards to inform best practice in research on consumer perspectives and experience and to support the implementation of codesigned and/or coproduced approaches in future research. Respecting and including consumers as equal partners in the research process will lead to more meaningful insights to inform policy and practice and reduce the life expectancy gap for people living with mental health concerns.
