Trace amine associated receptor 1: predicted effects of single nucleotide variants on structure-function in geographically diverse populations.

Trace Amine Associated Receptor 1 (TAAR1) is a novel pharmaceutical target under investigation for the treatment of several neuropsychiatric conditions. TAAR1 single nucleotide variants (SNV) have been found in patients with schizophrenia and metabolic disorders. However, the frequency of variants in geographically diverse populations and the functional effects of such variants are unknown. In this study, we aimed to characterise the distribution of TAAR1 SNVs in five different WHO regions using the Database of Genotypes and Phenotypes (dbGaP) and conducted a critical computational analysis using available TAAR1 structural data to identify SNVs affecting ligand binding and/or functional regions. Our analysis shows 19 orthosteric, 9 signalling and 16 micro-switch SNVs hypothesised to critically influence the agonist induced TAAR1 activation. These SNVs may non-proportionally influence populations from discrete regions and differentially influence the activity of TAAR1-targeting therapeutics in genetically and geographically diverse populations. Notably, our dataset presented with orthosteric SNVs D1033.32N (found only in the South-East Asian Region and Western Pacific Region) and T1945.42A (found only in South-East Asian Region), and 2 signalling SNVs (V1253.54A/T2526.36A, found in African Region and commonly, respectively), all of which have previously demonstrated to influence ligand induced functions of TAAR1. Furthermore, bioinformatics analysis using SIFT4G, MutationTaster 2, PROVEAN and MutationAssessor predicted all 16 micro-switch SNVs are damaging and may further influence the agonist activation of TAAR1, thereby possibly impacting upon clinical outcomes. Understanding the genetic basis of TAAR1 function and the impact of common mutations within clinical populations is important for the safe and effective utilisation of novel and existing pharmacotherapies.

Healthcare provider data breaches - framework for crisis communication and support of patients and healthcare workers in mental healthcare.

Increasing numbers of healthcare data breaches highlight the need for structured organisational responses to protect patients, trainees and psychiatrists against identity theft and blackmail. Evidence-based guidance that is informed by the COVID-19 pandemic response includes: timely and reliable information tailored to users' safety, encouragement to take protective action, and access to practical and psychological support. For healthcare organisations which have suffered a data breach, insurance essentially improves access to funded cyber security responses, risk communication and public relations. Patients, trainees and psychiatrists need specific advice on protective measures. Healthcare data security legislative reform is urgently needed.

Near-death experiences after cardiac arrest: a scoping review.

BACKGROUND: This scoping review aimed to characterise near-death experiences in the setting of cardiac arrest, a phenomenon that is poorly understood and may have clinical consequences. METHOD: PubMed/MEDLINE was searched to 23 July 2023 for prospective studies describing near-death experiences in cardiac arrest. PRISMA-ScR guidelines were adhered to. Qualitative and quantitative data were synthesised. Meta-analysis was precluded due to data heterogeneity. RESULTS: 60 records were identified, of which 11 studies involving interviews were included from various countries. Sample size ranged from 28-344, and proportion of female patients (when reported) was 0-50%, with mean age (when reported) ranging 54-64 years. Comorbidities and reasons for cardiac arrest were heterogeneously reported. Incidence of near-death experiences in the included studies varied from 6.3% to 39.3%; with variation between in-hospital (6.3-39.3%) versus out-of-hospital (18.9-21.2%) cardiac arrest. Individual variables regarding patient characteristics demonstrated statistically significant association with propensity for near-death experiences. Reported content of near-death experiences tended to reflect the language of the questionnaires used, rather than the true language used by individual study participants. Three studies conducted follow-up, and all suggested a positive life attitude change, however one found significantly higher 30-day all-cause mortality in patients with near-death experiences versus those without, in non-controlled analysis. CONCLUSIONS: From prospective studies that have investigated the phenomenon, near-death experiences may occur in as frequent as over one-third of patients with cardiac arrest. Lasting effects may follow these events, however these could also be confounded by clinical characteristics.

Can lithium be used in the setting of clozapine commencement in patients with COVID-19 associated neutropenia: A case report.

COVID-19 infection may increase the likelihood of neutropenia in patients already on clozapine. In clozapine treated patients experiencing COVID-19 associated neutropenia, adjunct therapy with lithium can be considered.

Comparison of the out-of-pocket costs of Medicare-funded telepsychiatry and face-to-face consultations: A descriptive study.

OBJECTIVE: Telepsychiatry items in the Australian Medicare Benefits Schedule (MBS) were expanded following the COVID-19 pandemic. However, their out-of-pocket costs have not been examined. We describe and compare patient out-of-pocket payments for face-to-face and telepsychiatry (videoconferencing and telephone) MBS items for outpatient psychiatric services to understand the differential out-of-pocket cost burden for patients across these modalities. METHODS: out-of-pocket cost information was obtained from the Medical Costs Finder website, which extracted data from Services Australia's Medicare claims data in 2021-2022. Cost information for corresponding face-to-face, video, and telephone MBS items for outpatient psychiatric services was compared, including (1) Median specialist fees; (2) Median out-of-pocket payments; (3) Medicare reimbursement amounts; and (4) Proportions of patients subject to out-of-pocket fees. RESULTS: Medicare reimbursements are identical for all comparable face-to-face and telepsychiatry items. Specialist fees for comparable items varied across face-to-face to telehealth options, with resulting differences in out-of-pocket costs. For video items, higher proportions of patients were not bulk-billed, with greater out-of-pocket costs than face-to-face items. However, the opposite was true for telephone items compared with face-to-face items. CONCLUSIONS: Initial cost analyses of MBS telepsychiatry items indicate that telephone consultations incur the lowest out-of-pocket costs, followed by face-to-face and video consultations.

The changing psychiatry workforce in Australia: Still lacking in rural and remote regions.

INTRODUCTION: There is a long standing and worsening shortage of psychiatrists in Australia particularly in rural areas. The majority of psychiatrists work in major cities. OBJECTIVE: To identify recent trends in the Australian rural psychiatrist workforce compared with the metropolitan workforce. DESIGN: We descriptively analysed population-level data from the National Health Workforce Data Set (NHWDS), the Australian Institute of Health and Welfare (AIHW) and the Australian Bureau of Statistics (ABS). A descriptive analysis of the numbers (count) and gender of psychiatrists from 1995 to 2022 working in Australia was conducted. For the period 2013 to 2022, we analysed for rurality, gender, years' experience, hours worked, Medicare-subsidised services provided and proportions of Specialist International Medical Graduates (SIMG) by sex, with a focus on the rural workforce. For international comparison, psychiatrist numbers were obtained for other OECD countries. The number of psychiatrists working in Australia, as per NHWDS and AIHW, was quantified. We analysed trends in demographics, hours worked and rurality of psychiatrists working in Australia in a serial cross-sectional design. FINDINGS: Most psychiatrists are maldistributed to major cities, while outer regional and remote areas have few resident psychiatrists. Outer regional New South Wales (NSW) and South Australia (SA) have the lowest numbers of psychiatrists per capita. The full-time equivalent (FTE) of psychiatrists per 100 000 has increased from 12.6 in 2000 to 15.2 in 2022. However, the average hours worked by psychiatrists has declined. In total, available psychiatrist hours worked per 100 000 population has increased by 6.1% since the beginning of the millennium. DISCUSSION: Rural areas in NSW and SA have the greatest shortage of psychiatrists. Specialist International Medical Graduates and females (43% of the overall workforce) are the predominant workforce in rural areas. Although Medicare-subsidised services per 1000 people have increased in rural areas, they remain lower than for those living in major cities. CONCLUSION: There remains an acute shortage of psychiatrists in many regional and remote areas of Australia, with an increasing proportion of SIMGs and females working in these areas, in the context of future increased demand.

Seasonal Surge for Mental Health Demand in Emergency Departments.

Objective: To analyze emergency department (ED) mental health presentations over a 7-year period to estimate the timing and magnitude of the seasonal effect across Australia.Methods: We analyzed data collected by the Australian Institute of Health and Welfare (AIHW) from 2014-2015 to 2020-2021, which included all public hospital ED presentations in Australia that received a mental health diagnosis per the Australian Modification of ICD-10. The data were divided into 4 sequential quarters (Q1 = July-September, Q2 = October-December, Q3 = January-March, Q4 = April-June) and analyzed by sex and age (youth: 18-24 years, adult: 25-64 years, and older adult: > 65 years). Regression analysis was used to assess seasonal variation.Results: On average, mental health ED presentations were 9% higher in October-December than April-June, which had the lowest rates of mental health ED presentations for males and females. The peak continued into January-March, most prominently for females. Seasonality was evident in the 18-24 and 25-64 age groups. There were increased ED psychiatry presentations in October-December of 14.4% (males) and 9% (females) in the group aged 18-24, as well as increases of 10.3% (males) and 10.1% (females) in those aged 25-64. In January-March, there was an increase in presentations for females of 7% (aged 18-24) and 10.3% (aged 25-64). For adults aged > 65, there were increased presentations in July-September compared to April-June of 4.9% (males) and 3.9% (females).Conclusions: We found strong, statistically significant peaks in mental health ED presentations in spring and summer. Mental health services need to plan for significantly higher ED mental health demand during these seasons. Further research is required to estimate the size of the mental health seasonal effect in acute hospital settings.Prim Care Companion CNS Disord 2024;26(1):23m03629.

Psychiatric electronic health records in the era of data breaches - What are the ramifications for patients, psychiatrists and healthcare systems?

OBJECTIVE: To update psychiatrists and trainees on the realised risks of electronic health record data breaches. METHODS: This is a selective narrative review and commentary regarding electronic health record data breaches. RESULTS: Recent events such as the Medibank and Australian Clinical Labs data breaches demonstrate the realised risks for electronic health records. If stolen identity data is publicly released, patients and doctors may be subject to blackmail, fraud, identity theft and targeted scams. Medical diagnoses of psychiatric illness and substance use disorder may be released in blackmail attempts. CONCLUSIONS: Psychiatrists, trainees and their patients need to understand the inevitability of electronic health record data breaches. This understanding should inform a minimised collection of personal information in the health record to avoid exposure of confidential information and identity theft. Governmental regulation of electronic health record privacy and security is needed.

Medicare Benefits Schedule (MBS) Review Advisory Committee post-implementation review of MBS telehealth items: abolition of initial telehealth consultations for non-general practitioner specialists.

In 2022, the Australian Federal Minister for Health and Aged Care commissioned the Medicare Benefits Schedule (MBS) Review Advisory Committee (MRAC) to conduct a post-implementation review of MBS telehealth services, including settings of video and telephone consultations. The MRAC has made a series of administrative recommendations for telehealth practice that appear at cross-purposes to the evidence-base on medical consultations and that would limit patient access to medical specialist assessment in Australia. These recommendations particularly underestimate the role of telehealth in rural and remote Australia and did not take into account high patient satisfaction with telehealth assessment and treatment during the ongoing coronavirus disease 2019 (COVID-19) pandemic. They also appear to contradict the Medical Board of Australia's guidance on telehealth. On this basis, the recommendations for telehealth principles and abolition of reimbursement for telehealth for all initial non-general practitioner medical specialist consultations should be withdrawn.

Recurrent Mental Health Presentations to Public Hospital Services: A Focus on Borderline Personality Disorder.

Objective: To investigate associations between patients with borderline personality disorder (BPD)-related symptoms and their hospital presentations as well as the effect of inpatient length of stay (LOS) on time to hospital re-presentation.Methods: A retrospective cohort design was used to investigate mental health emergency department (ED) visits and inpatient admissions. The cohort comprised 13,320 men and 12,290 women with a follow-up period between January 1, 2014, and December 31, 2019.Results: Across all presentations in the study period, approximately 4% of mental health patients were discharged from ED or inpatient admission with primary diagnosis of BPD. Both male and female patients with BPD were at higher risk of hospital re-presentation when compared to patients with any other type of mental disorder (P < .01). Patients with BPD who had LOS > 14 days in their first inpatient admission were, on average, more likely to experience a repeat ED or inpatient presentation 58 days sooner than patients who had LOS < 2 days (P = .036).Conclusions: Findings suggest the need for (a) more accurate recording of BPD and related presentations, (b) more in-depth investigations of BPD care pathways, and (c) identifications of subpopulations who may benefit from a specific inpatient length of stay.Prim Care Companion CNS Disord 2024;26(1):23m03559.

Practical psychiatry: On therapeutic equipoise - Principles of a balanced approach to psychiatric treatments.

OBJECTIVE: There are many burgeoning treatments, and a large range of therapeutic options for 21st century psychiatry. This paper briefly comments upon considerations for balancing treatment to suit the patient, their illness, and their milieu. CONCLUSIONS: Therapeutic equipoise, for psychiatric care, is an aspiration rather than a position easily achieved. In day-to-day clinical practice, there will be unexpected demands and barriers that cannot always be accommodated or surmounted. Psychiatrists can work collaboratively with patients, carers, and colleagues in conceptualising and care-planning to avoid extremes of therapeutic hubris and despair, and to adapt evidence-based care more effectively so that it is suited to the patient and their circumstances.

Practical psychiatry: Taking gaming seriously - a primer for psychiatrists on gamers and gaming culture.

OBJECTIVE: Up to three billion, of the eight billion people in the world, play videogames. Gaming is a significant global sociocultural influence. This primer will aid psychiatrists in understanding sociocultural milieux of gamers, who include patients and their communities. METHOD: A rapid narrative review. RESULTS: Benefits include expression of personality, identity and culture through social aspects of gaming. Improved physical health, neurocognition, self-efficacy and quality of life are associated with gaming in those with certain mental health disorders including schizophrenia. Harms may include in-game discrimination, disordered gaming, as well as encouragement of online gambling. There is no longitudinal association between violent games and youth aggression. CONCLUSIONS: Psychiatrists should enquire about gaming as part of the sociocultural milieux of patients' lives, and the perceived mental health benefits and harms of gaming.

Mitigating the consequences of electronic health record data breaches for patients and healthcare workers.

Electronic health records (EHRs) have been widely adopted in Australian public sector healthcare and will remain an ongoing, essential data system. However, recent substantial data breaches from hacked business data systems in Australian enterprises, as well as international healthcare providers, mean that EHR data breaches are increasingly likely in Australia. Risks include medical identity theft and extortion attempts based on threats to release sensitive patient information. Hacking is now a foreseeable additional risk of medical treatment. Risk mitigation for the consequences of data breaches needs to be considered, as well as support for patients (and families) and healthcare workers. This includes identity theft protection services, cybersecurity insurance, and psychological support.

Unpeeling the onion: Digital triage and monitoring of general practice, private psychiatry, and psychology.

OBJECTIVE: The Australian federal government is considering a 'digital front door' to mental healthcare. The Brain and Mind Centre at the University of Sydney has published a discussion paper advocating that the government should adopt a comprehensive model of digital triage and monitoring (DTM) based on a government-funded initiative Project Synergy ($30 million). We critically examine the final report on Project Synergy, which is now available under a Freedom of Information request. CONCLUSION: The DTM model is disruptive. Non-government organisations would replace general practitioners as care coordinators. Patients, private psychiatrists, and psychologists would be subjected to additional layers of administration, assessment, and digital compliance, which may decrease efficiency, and lengthen the duration of untreated illness. Only one patient was deemed eligible for DTM, however, during the 8-month regional trial of Project Synergy (recruitment rate = 1/500,000 across the region). Instead of an unproven DTM model, the proposed 'digital front door' to Australian mental healthcare should emphasise technology-enabled shared care (general practitioners and mental health professionals) for the treatment of moderate-to-severe illness.
