Cardiovascular risk factors for people with mental illness

The objective of this study was to document the prevalence of risk factors for cardiovascular disease among people with chronic mental illness.

Assessing cost-effectiveness in mental health : vocational rehabilitation for schizophrenia and related conditions

Objective: Existing evidence suggests that vocational rehabilitation services, in particular individual placement and support (IPS), are effective in assisting people with schizophrenia and related conditions gain open employment. Despite this, such services are not available to all unemployed people with schizophrenia who wish to work. Existing evidence suggests that while IPS confers no clinical advantages over routine care, it does improve the proportion of people returning to employment. The objective of the current study is to investigate the net benefit of introducing IPS services into current mental health services in Australia.

Method: The net benefit of IPS is assessed from a health sector perspective using cost–benefit analysis. A two-stage approach is taken to the assessment of benefit. The first stage involves a quantitative analysis of the net benefit, defined as the benefits of IPS (comprising transfer payments averted, income tax accrued and individual income earned) minus the costs. The second stage involves application of 'second-filter' criteria (including equity, strength of evidence, feasibility and acceptability to stakeholders) to results. The robustness of results is tested using the multivariate probabilistic sensitivity analysis.

Results: The costs of IPS are $A10.3M (95% uncertainty interval $A7.4M–$A13.6M), the benefits are $A4.7M ($A3.1M–$A6.5M), resulting in a negative net benefit of $A5.6M ($A8.4M–$A3.4M).

Conclusions: The current analysis suggests that IPS costs are greater than the monetary benefits. However, the evidence-base of the current analysis is weak. Structural conditions surrounding welfare payments in Australia create disincentives to full-time employment for people with disabilities.

Nutrition and mental health research in Australia and New Zealand: A review of progress and directions for the future

This review summarises nutrition and mental health research in Australia and New Zealand between 1986 and 2006. The method used to identify papers for inclusion was a search of computerised databases: Medline, Cinahl and Meditext 1986–2006, with subsequent bibliographical review. Key search words were nutrition, diet, mental disorder, mental illness, weight, physical health, Australia and New Zealand. Inclusion criteria included: English language, original data in peer reviewed journals, and examination of some component of nutrition in people with a mental illness. The review of thirteen papers found that the evidence base for dietetic practice in mental health has developed through small assessment and interventional research, often with multidisciplinary collaboration. Future research should include quality and outcome measures with intersectoral partnerships. Dietitians are well positioned to lead and participate in mental health research and to implement research findings to improve the nutritional status of this vulnerable group.

Chronic mental stress is a cause of essential hypertension : presence of biological markers of stress

1. In searching for biological evidence that essential hypertension is caused by chronic mental stress, a disputed proposition, parallels are noted with panic disorder, which provides an explicit clinical model of recurring stress responses.
2. There is clinical comorbidity; panic disorder prevalence is increased threefold in essential hypertension. Plasma cortisol is elevated in both.
3. In panic disorder and essential hypertension, but not in health, single sympathetic nerve fibres commonly fire repeatedly within an individual cardiac cycle; this appears to be a signature of stress exposure. For both conditions, adrenaline cotransmission is present in sympathetic nerves.
4. Tissue nerve growth factor is increased in both (nerve growth factor is a stress reactant). There is induction of the adrenaline synthesizing enzyme, phenylethanolamine-N-methyltransferase, in sympathetic nerves, an explicit indicator of mental stress exposure.
5. The question of whether chronic mental stress causes high blood pressure, still hotly debated, has been reviewed by an Australian Government body, the Specialist Medical Review Council. Despite the challenging medicolegal implications, the Council determined that stress is one proven cause of hypertension, this ruling being published in the 27 March 2002 Australian Government Gazette. This judgement was reached after consideration of the epidemiological evidence, but in particular after review of the specific elements of the neural pathophysiology of essential hypertension, described above.

Practical application of the Delphi technique in a bicultural mental health nursing study in New Zealand

Background. Numerous studies have employed the Delphi technique to seek expert opinion about aspects of clinical practice. When researching literature on the Delphi technique, however, we discovered discrepancies in its application, and a lack of detail when reporting design, administration, and analysis methods. Such lack of specificity hinders the replicability and assessment of the clinical and cultural validity and reliability of Delphi studies.

Aim. The aim of this paper is to detail the practical application of the Delphi technique as a culturally and clinically valid means of accessing expert opinion on the importance of clinical criteria.

Methods. Reference is made to a bicultural New Zealand mental health nursing clinical indicator study that employed a three-round reactive Delphi survey. Equal proportions of Maori and non-Maori nurses (n = 20) and consumers (n = 10) rated the importance of 91 clinical indicator statements for the achievement of professional practice standards. Additional statements (n = 21) suggested by Delphi participants in round 1 were included in subsequent rounds. In round 2, participants explained the rating they applied to statements that had not reached consensus in round 1, and summarized responses were provided to participants in round 3. Consensus was considered to have been achieved if 85% of round 3 ratings lay within a 2-point bracket on the 5-point Likert-scale overall, or in one of the Maori nurse, non-Maori nurse, or consumer groups. A mean rating of 4·5 after round 3 was set as the importance threshold.

Findings. Consensus occurred overall on 75 statements, and within groups on another 24. Most statements (n = 86) reached the importance benchmark.

Conclusions. When rigorous methods of participant selection, group composition, participant feedback, and determination of consensus and importance are employed, the Delphi technique is a reliable, cost-effective means of obtaining and prioritizing experts judgements.

Development of a professional practice audit questionnaire for mental health nursing in Aotearoa/New Zealand

This paper reports the three-stage development of a professional practice audit questionnaire for mental health nursing in Aotearoa/New Zealand. In Study 1, clinical indicator statements (n = 99) generated from focus group data, which were considered to be unobservable in the nursing documentation in consumer case notes, were included in a three-round Delphi process. Consensus of ratings occurred for the mental health nurse and academic participants (n = 7) on 83 clinical indicator statements. In Study 2, the clinical indicator statements (n = 67) that met importance and consensus criteria were incorporated into a questionnaire, which was piloted at a New Zealand mental health service. The questionnaire was then modified for use in a national field study. In Study 3, the national field study, registered mental health nurses (n = 422) from 11 New Zealand District Health Board mental health services completed the questionnaire. Five categories of nursing practice were identified: professional and evidence-based practice; consumer focus and reflective practice; professional development and integration; ethically and legally safe practice; and culturally safe practice. Analyses revealed little difference in the perceptions of nurses from different backgrounds regarding the regularity of the nursing practices. Further research is needed to calibrate the scores on each clinical indicator statement with behaviour in clinical practice.

Evaluation of a community-based mental health drug and alcohol nurse in the care of people living with HIV/AIDS

There is a growing need for advanced practice mental health and drug and alcohol nursing roles in the care of people living with HIV/AIDS; however, limited publications address these domains. This study evaluated a community-based mental health drug and alcohol nurse role caring for people living with HIV/AIDS (Mental Health D&A Nurse) in a large not-for-profit district nursing organization providing care to people living with HIV/AIDS in an Australian city. Outcomes from a client assessment and 6–8-week follow-up by the Mental Health D&A Nurse are presented as captured by the Depression Anxiety Stress Scales (DASS 21), Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), Health of the Nation Outcome Scales (HONOS) and WHOQoL BREF. Mean scores and caseness were analysed, and significant differences were found on the 'impairment' and 'social problems' subscales of the HONOS. Results of semi-structured interviews with clients describe effective and supportive mental health care and health-promoting education following visits by the Mental Health D&A Nurse. These positive findings support continuing implementation of the role within this community setting and indicate that even greater benefits will ensue as the role develops further. Findings are of interest to clinicians and policy makers seeking to implement similar roles in community-based HIV/AIDS care.

Mental health triage nursing : an Australian perspective

This paper presents the findings of a doctoral research project that involved a state-wide investigation into mental health triage nursing in Victoria, Australia. Mental health triage is a specialized domain of nursing practice that has emerged within the context of wider mental health reform in the State. The overall aim of the study was to produce a comprehensive definition and description of psychiatric triage nursing in Victoria. Methodological triangulation was used in the design of the study to enable the use of both survey (n = 139) and semi-structured interview (n = 21) data collection methods. Mental health triage nursing was found to be a complex, stressful role that involves high levels of responsibility, clinical decision making, and multiple role functions, many of which overlap into areas of practice previously the exclusive domain of medicine, such as assessment, diagnosis, and referral. The paper raises discussion on contemporary professional issues of concern to mental health triage nursing, and concludes with recommendations for the future development of the discipline.

Mental health triage : towards a model for nursing practice

Mental health triage/duty services play a pivotal role in the current framework for mental health service delivery in Victoria and other states of Australia. Australia is not alone in its increasing reliance on mental health triage as a model of psychiatric service provision; at a global level, there appears to be an emerging trend to utilize mental health triage services staffed by nurses as a cost-effective means of providing mental health care to large populations. At present, nurses comprise the greater proportion of the mental health triage workforce in Victoria and, as such, are performing the majority of point-of-entry mental health assessment across the state. Although mental health triage/duty services have been operational for nearly a decade in some regional healthcare sectors of Victoria, there is little local or international research on the topic, and therefore a paucity of established theory to inform and guide mental health triage practice and professional development. The discussion in this paper draws on the findings and recommendations of PhD research into mental health triage nursing in Victoria, to raise discussion on the need to develop theoretical models to inform and guide nursing practice. The paper concludes by presenting a provisional model for mental health triage nursing practice.

Assessing cost-effectiveness in mental health: helping policy-makers prioritize and plan health services

Objective: We assessed, from a health sector perspective, options for change that could improve the efficiency of Australia's current mental health services by directing available resources toward 'best practice' cost-effective services.

Method: We summarize cost-effectiveness results of a range of interventions for depression, schizophrenia, attention deficit hyperactivity disorder and anxiety disorders that have been presented in previous papers in this journal. Recommendations for change are formulated after taking into account 'second-filter criteria' of equity, feasibility of implementing change, acceptability to stakeholders and the strength of the evidence. In addition, we estimate the impact on total expenditure if the recommended mental health interventions for depression and schizophrenia are to be implemented in Australia.

Results: There are cost-effective treatment options for mental disorders that are currently underutilized (e.g. cognitive–behavioural therapy (CBT) for depression and anxiety, bibliotherapy for depression, family interventions for schizophrenia and clozapine for the worst course of schizophrenia). There are also less cost-effective treatments in current practice (e.g. widespread use of olanzapine and risperidone in the treatment of established schizophrenia and, within those atypicals, a preference for olanzapine over risperidone). Feasibility of funding mechanisms and training of staff are the main second-filter issues for CBT and family interventions. Acceptability to various stakeholders is the main barrier to implementation of more cost-effective drug treatment regimens. More efficient drug intervention options identified for schizophrenia would cost A$68 million less than current practice. These savings would more than cover the estimated A$36M annual cost of delivering family interventions to the 51% of people with schizophrenia whom we estimated to be eligible and this would lead to an estimated 12% improvement in their health status. Implementing recommended strategies for depression would cost A$121M annually for the 24% of people with depression who seek care currently, but do not receive an evidence-based treatment.

Conclusions: Despite considerable methodological problems, a range of cost-effective and less cost-effective interventions for major mental disorders can be discerned. The biggest hurdle to implementation of more efficient mental health services is that this change would require reallocation of funds between interventions, between disorders and between service providers with different funding mechanisms.

Mental health and life satisfaction of young Australians : the role of family background

This paper uses the Household, Income and Labour Dynamics in Australia Survey to investigate the factors that influence young Australians’ mental health and life satisfaction, with an emphasis upon the role of family background. It also explores male and female differences concerning those background effects. The results indicate a particularly significant negative association between parental divorce and well-being, and suggest that the timing of divorce matters. Distinguishing the samples by gender shows that this relationship remains significant only for females. Past living arrangements consistently turn out to be statistically insignificant whether the sample used is the total, males or females. The current living arrangements, however, appear to be significantly associated with both mental health and life satisfaction of males. Adding potentially confounding characteristics to our basic regression, which includes only the family background variables, suggests that some of the ‘aggregate’ effects of family background might work indirectly through the mediating variables such as education or lifestyles, though most of them remain direct. Among those, marital status, education, labour market experience and lifestyles seem to be the major factors explaining the dispersion in well-being of young Australians. Income and wealth, on the other hand, have only a minor impact.

Mindfulness in forensic mental health : does it have a role?

Treatment and rehabilitation in forensic settings have been largely based on cognitive behavioural models and therapies. In the past decade, “third wave” approaches have developed in cognitive behavioural therapy, strongly influenced by spiritual and contemplative traditions such as Buddhism. Mindfulness is the most analysed and researched of such approaches. In this paper, we ask whether mindfulness is relevant to therapeutic work with offenders in forensic mental health and criminal justice services. We review the known criminogenic and other needs of offender groups and discuss whether the psychological processes affected by mindfulness are relevant to reducing risk, alleviating distress and facilitating coping. We conclude that they are. Finally, we address some of the problems that may arise in implementing mindfulness interventions in forensic settings.
