Improving the cardiometabolic health of people with psychosis: A protocol for a randomised controlled trial of the Physical Health Nurse Consultant service

Physical Health and Health Behaviours of Australians with Psychosis

People living with psychosis live up to 20 years less compared to the general population. Cardiometabolic ill-health and barriers to health-related behaviour are significant contributors. This is a cross-sectional descriptive study of cardiometabolic health and health behaviours of consumers attending a public community mental health service in an Australian city. One hundred and fourteen consumers currently living with psychosis participated. Standard measures of cardiometabolic health, quality of life and, health-related behaviours were utilised. Data were analysed using descriptive statistics. The cohort reported higher fruit intake and physical activity, and lower excess alcohol use compared to previous studies. Health-related behaviours including smoking and vegetable intake were poorer than previously reported. Participants had low levels of cardiometabolic health (e.g. abnormal lipids). Physical and mental quality of life was also lower than for general populations. Improved efforts to address physical health for people with mental health conditions are urgently needed.

Healthcare Professional Perspectives on the Impact of the Physical Health Nurse Consultant

Early mortality experienced by people living with mental health issues (hereon termed consumers) is largely preventable. Healthcare professionals perceive healthcare system inadequacies such as diagnostic overshadowing, stigma and fragmentation of physical and mental healthcare services can be resolved through effective integration approaches. Service- and individual-level integration approaches involve multidisciplinary teams collaborating and coordinating care to holistically meet consumers' physical and mental health needs. Evidence suggests appropriately trained healthcare professionals can deliver effective integrated treatment without financial or organisational restructuring. Specialist nursing positions such as Physical Health Nurse Consultants can support and integrate physical and mental health care. Consumers report the Physical Health Nurse Consultant as providing dedicated, integrated, coordinated and holistic mental and physical health care. This study aimed to explore the Physical Health Nurse Consultant role from the perspectives of healthcare professionals. A qualitative exploratory study design was used. Fourteen healthcare professionals participated in individual interviews or focus groups. Interview recordings were transcribed, and thematically analysed. Three themes were identified: (i) role functions, including integration of physical and mental health care, (ii) impact on consumer physical health outcomes and (iii) impact on service delivery. Healthcare professionals perceive the Physical Health Nurse Consultant effectively integrates physical and mental health care and subsequently support the continuation and embedding of the role in routine practice. Future research is required to explore healthcare professionals' experiences and perceptions of how these roles be translated to routine clinical practice. Examining the professional development requirements, service provider constraints and economic implication to achieve these outcomes also warrants attention.

The Physical Health Nurse Consultant: Perceptions and Experiences of Those Who Care for People with Mental Illness

Mental health carers are crucial in improving the physical health outcomes of people diagnosed with a mental illness (hereafter referred to as consumers). The long-term and multifaceted mental and physical health support carers provide to consumers can contribute to caregiver burden. Consequently, carers advocate for coordinated and integrated physical healthcare to improve the physical health outcomes of consumers and alleviate caregiver burden. The aim of this qualitative exploratory study is to explore carers' perceptions and experiences with the Physical Health Nurse Consultant role. Semi-structured interviews with nine carers nominated by consumers were conducted. Interviews were transcribed and reflexively thematically analysed. Three main themes were identified: (i) Therapeutic relationship s were a catalyst for health behaviour change; (ii) Overt and covert positive changes were observed by carer and (iii) Cares' involvement in integrated mental health and physical health care. Nine carers who were nominated by consumers to be involved in their physical healthcare planning, preferred to adopt a supporting role as this prevented or reduced caregiver burden. The findings support the adoption and continuation of the Physical Health Nurse Consultant role to facilitate positive physical health outcomes for consumers and a reduction in caregiving burden. The benefits of the Physical Health Nurse Consultant provide a compelling argument to embed the role in routine practice. Mental healthcare services should advocate for continued funding and career development for such positions to provide long term benefits for consumers and carers. Future research is required to explore carer and consumer involvement in co-producing future and localised iterations of the Physical Health Nurse Consultant role. This research should also measure the outputs and outcomes of co-production to clarify how the process worked in practice.

Nurse-led physical health interventions for people with mental illness: an integrative review of international literature

BACKGROUND

People experiencing mental illness receive physical healthcare from nurses in a variety of settings including acute inpatient, secure extended care, forensic, and community services. While nurse-led clinical practice addressing sub-optimal consumer physical health is salient, a detailed understanding and description of the contribution by nurses to physical health interventions in people experiencing mental illness is not clearly articulated in the literature.

AIMS

The aim of this integrative review is to describe the state of knowledge on nurse-led physical health intervention for consumers, focusing on nursing roles, nursing assessment, and intervention settings.

METHODS

A systematic search of six databases using Medical Subject Headings from 2001 and 2022 inclusive was conducted. The Mixed Methods Appraisal Tool (MMAT) was utilised for quality appraisal.

RESULTS

Seventy-four studies were identified as "nurse-led". Interventions were most common among community settings (n = 34, 46%). Nurses performed varied roles, often concurrently, including the collection of 341 physical health outcomes, and multiple roles with 225 distinct nursing actions identified across the included studies. A nurse as lead author was common among the included studies (n = 46, 62%). However, nurses were not always recognised for their efforts or contributions in authorship.

CONCLUSIONS

There is potential gap in role recognition that should be considered when designing and reporting nurse-led physical health interventions.

Collaborative care approaches for people with severe mental illness

BACKGROUND

Collaborative care for severe mental illness (SMI) is a community-based intervention that promotes interdisciplinary working across primary and secondary care. Collaborative care interventions aim to improve the physical and/or mental health care of individuals with SMI. This is an update of a 2013 Cochrane review, based on new searches of the literature, which includes an additional seven studies.

OBJECTIVES

To assess the effectiveness of collaborative care approaches in comparison with standard care (or other non-collaborative care interventions) for people with diagnoses of SMI who are living in the community.

SEARCH METHODS

We searched the Cochrane Schizophrenia Study-Based Register of Trials (10 February 2021). We searched the Cochrane Common Mental Disorders (CCMD) controlled trials register (all available years to 6 June 2016). Subsequent searches on Ovid MEDLINE, Embase and PsycINFO together with the Cochrane Central Register of Controlled Trials (with an overlap) were run on 17 December 2021.

SELECTION CRITERIA

Randomised controlled trials (RCTs) where interventions described as 'collaborative care' were compared with 'standard care' for adults (18+ years) living in the community with a diagnosis of SMI. SMI was defined as schizophrenia, other types of schizophrenia-like psychosis or bipolar affective disorder. The primary outcomes of interest were: quality of life, mental state and psychiatric admissions at 12 months follow-up.

DATA COLLECTION AND ANALYSIS

Pairs of authors independently extracted data. We assessed the quality and certainty of the evidence using RoB 2 (for the primary outcomes) and GRADE. We compared treatment effects between collaborative care and standard care. We divided outcomes into short-term (up to six months), medium-term (seven to 12 months) and long-term (over 12 months). For dichotomous data we calculated the risk ratio (RR) and for continuous data we calculated the standardised mean difference (SMD), with 95% confidence intervals (CIs). We used random-effects meta-analyses due to substantial levels of heterogeneity across trials. We created a summary of findings table using GRADEpro.

MAIN RESULTS

Eight RCTs (1165 participants) are included in this review. Two met the criteria for type A collaborative care (intervention comprised of the four core components). The remaining six met the criteria for type B (described as collaborative care by the trialists, but not comprised of the four core components). The composition and purpose of the interventions varied across studies. For most outcomes there was low- or very low-certainty evidence. We found three studies that assessed the quality of life of participants at 12 months. Quality of life was measured using the SF-12 and the WHOQOL-BREF and the mean endpoint mental health component scores were reported at 12 months. Very low-certainty evidence did not show a difference in quality of life (mental health domain) between collaborative care and standard care in the medium term (at 12 months) (SMD 0.03, 95% CI -0.26 to 0.32; 3 RCTs, 227 participants). Very low-certainty evidence did not show a difference in quality of life (physical health domain) between collaborative care and standard care in the medium term (at 12 months) (SMD 0.08, 95% CI -0.18 to 0.33; 3 RCTs, 237 participants). Furthermore, in the medium term (at 12 months) low-certainty evidence did not show a difference between collaborative care and standard care in mental state (binary) (RR 0.99, 95% CI 0.77 to 1.28; 1 RCT, 253 participants) or in the risk of being admitted to a psychiatric hospital at 12 months (RR 5.15, 95% CI 0.67 to 39.57; 1 RCT, 253 participants). One study indicated an improvement in disability (proxy for social functioning) at 12 months in the collaborative care arm compared to usual care (RR 1.38, 95% CI 0.97 to 1.95; 1 RCT, 253 participants); we deemed this low-certainty evidence. Personal recovery and satisfaction/experience of care outcomes were not reported in any of the included studies. The data from one study indicated that the collaborative care treatment was more expensive than standard care (mean difference (MD) international dollars (Int$) 493.00, 95% CI 345.41 to 640.59) in the short term. Another study found the collaborative care intervention to be slightly less expensive at three years.

AUTHORS' CONCLUSIONS

This review does not provide evidence to indicate that collaborative care is more effective than standard care in the medium term (at 12 months) in relation to our primary outcomes (quality of life, mental state and psychiatric admissions). The evidence would be improved by better reporting, higher-quality RCTs and the assessment of underlying mechanisms of collaborative care. We advise caution in utilising the information in this review to assess the effectiveness of collaborative care.

The physical health nurse consultant and mental health consumer: An important therapeutic partnership

People diagnosed with mental illness (hereon referred to as consumers) experience a disproportionately lower life expectancy of up 30 years compared to the general population. Systemic issues such as diagnostic overshadowing and stigma from healthcare professionals have inhibited the development of positive therapeutic partnerships that enable consumers to seek and engage support for their physical health concerns. Consumers have called for healthcare professionals to skillfully develop and prioritize therapeutic partnerships whilst coordinating and providing physical healthcare. The aim of this qualitative descriptive research was to explore consumer views and experiences of their interactions with a specialist mental health nursing role, the Physical Health Nurse Consultant. Semi-structured interviews were conducted with 14 consumers from a large public Community Mental Health Service in the Australian Capital Territory. Interviews were transcribed and thematically analysed. Therapeutic partnerships were an overarching theme identified from the data and included three sub-themes: personal attributes of the Physical Health Nurse Consultant; behaviour change engagement strategies; and impact of the therapeutic partnership. Consumers described the personal and professional attributes of the Physical Health Nurse Consultant that enabled the establishment and maintenance of their highly valued therapeutic partnership. This therapeutic partnership was perceived to positively impact their personal and clinical outcomes. With increasing support from consumers, clinical practice settings should move towards embedding a Physical Health Nurse Consultant role in routine practice. Further research exploring the co-development of health behaviour change goals and, barriers and facilitators experienced by the consumers regarding the Physical Health Nurse Consultant is required to further role development.

Interventions to Promote the Utilization of Physical Health Care for People with Severe Mental Illness: A Scoping Review

BACKGROUND

The main contributor to excess mortality in severe mental illness (SMI) is poor physical health. Causes include unfavorable health behaviors among people with SMI, stigmatization phenomena, as well as limited access to and utilization of physical health care. Patient centered interventions to promote the utilization of and access to existing physical health care facilities may be a pragmatic and cost-effective approach to improve health equity in this vulnerable and often neglected patient population.

OBJECTIVE/METHODS

In this study, we systematically reviewed the international literature on such studies (sources: literature databases, trial-registries, grey literature). Empirical studies (quantitative, qualitative, and mixed methods) of interventions to improve the utilization of and access to medical health care for people with a SMI, were included.

RESULTS

We identified 38 studies, described in 51 study publications, and summarized them in terms of type, theoretical rationale, outcome measures, and study author's interpretation of the intervention success.

CONCLUSIONS

Useful interventions to promote the utilization of physical health care for people with a SMI exist, but still appear to be rare, or at least not supplemented by evaluation studies. The present review provides a map of the evidence and may serve as a starting point for further quantitative effectiveness evaluations of this promising type of behavioral intervention.

Mental health consumers' perspectives of physical health interventions: An integrative review

Consumers of mental health services experience poor physical health compared to the general population, leading to long-term physical illness and premature death. Current research and policy activity prioritizes the physical health of consumers yet few of these recommendations have translated to practice. This implementation gap may be influenced by the paucity of literature exploring consumer perceptions and experiences with physical healthcare and treatment. As a result, little is understood about the views and attitudes of consumers towards interventions designed to improve their physical health. This integrative review aims to explore the literature regarding consumer perspectives of physical healthcare and, interventions to improve their physical health. A systematic search was undertaken using (i) CINAHL, (ii) MEDLINE, (iii) PsycINFO, (iv) Scopus, and (v) Google Scholar between September and December 2021. Sixty-one papers comprising 3828 consumer participants met the inclusion criteria. This review found that consumers provide invaluable insights into the barriers and enablers of physical healthcare and interventions. When consumers are authentically involved in physical healthcare evaluation, constructive and relevant recommendations to improve physical healthcare services, policy, and future research directions are produced. Consumer evaluation is the cornerstone required to successfully implement tailored physical health services.

Prevalence of Chronic Health Conditions in Australian Adults with Depression and/or Anxiety

The association between psychotic illness and poor physical health is now clearly articulated in the literature. By contrast the impact of depression and/or anxiety on physical health is considerably less understood, despite depression being the leading cause of disability worldwide and is associated with significantly higher prevalence of physical comorbidities than found in the general population. An Australia national cross-sectional population-based survey was conducted to ascertain the prevalence of chronic physical health conditions in persons with, and without depression and/or anxiety, allowing for demographic characteristics and lifestyle factors. The telephone-based survey was conducted using trained interviewers. Survey questions included those eliciting information about demographics, health status, and health behaviours. Independent t-tests and chi square tests showed demographic, health behaviours, and physical illness differed between those with and without depression and/or anxiety. Heart disease, high blood pressure, stroke, cancer, arthritis, chronic neck and/or back pain, and asthma were significantly higher in participants diagnosed with depression and/or anxiety. Binary logistic regression showed the strongest predictor of chronic illness was having a diagnosis of depression and/or anxiety. Depression and anxiety present major health problems impacting a considerable proportion of the population. A greater understanding of the associated physical health issues should provide impetus to broaden the physical health and mental illness research agenda to include these diagnoses.
