Occupational therapy and clinical research in mental health rehabilitation

Practitioners working in Australian mental health services are faced with the challenge of providing appropriate evidence-based interventions that lead to measurable improvement and good outcomes. Current government policy is committed to the development of strategic mental health research. One focus has been on under-researched practice areas, which include the development of psychosocial rehabilitation systems and models that facilitate recovery. To meet this challenge, an Australian rehabilitation service formed a collaborative partnership with a university. The purposes of the collaboration were to implement new forms of service delivery based on consumer need and evidence and to design research projects to evaluate components of the rehabilitation programme. This article examines the process of developing the collaboration and provides examples of how research projects have been used to inform practice and improve the effectiveness of service delivery. Challenges to the sustainability of this kind of collaboration are considered.

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.

Lessons from the National Mental Health Integration Program

Three projects were funded under the national Mental Health Integration Program (MHIP) in 1999, each of which employed a different model aimed at improving linkages between disparate parts of the mental health system. A national evaluation framework guided local evaluations of these projects, and this paper presents a synthesis of the findings. For providers, the projects improved working relationships, created learning opportunities and increased referral and shared care opportunities. For consumers and carers, the projects resulted in a greater range of options and increased continuity of care. For the wider system, the projects achieved significant structural and cultural change. Cost-wise, there were no increases in expenditure, and even some reductions. Many of the lessons from the projects (and their evaluations) may be generalised to other mental health settings and beyond.

Attaching unit costs to Australia's National Survey of Mental Health and Wellbeing

Background: In mental health, policy-makers and planners are increasingly being asked to set priorities. This means that health economists, health services researchers and clinical investigators are being called upon to work together to define and measure costs. Typically, these researchers take available service utilisation data and convert them to costs, using a range of assumptions. There are inefficiencies, as individual groups of researchers frequently repeat essentially similar exercises in achieving this end. There are clearly areas where shared or common investment in the development of statistical software syntax, analytical frameworks and other resources could maximise the use of data. Aims of the Study: This paper reports on an Australian project in which we calculated unit costs for mental health admissions and community encounters. In reporting on these calculations, our purpose is to make the data and the resources associated with them publicly available to researchers interested in conducting economic analyses, and allow them to copy, distribute and modify them, providing that all copies and modifications are available under the same terms and conditions (i.e., in accordance with the 'Copyleft' principle), Within this context, the objectives of the paper are to: (i) introduce the 'Copyleft' principle; (ii) provide an overview of the methodology we employed to derive the unit costs; (iii) present the unit costs themselves; and (iv) examine the total and mean costs for a range of single and comorbid conditions, as an example of the kind of question that the unit cost data can be used to address. Method: We took relevant data from the Australian National Survey of Mental Health and Wellbeing (NSMHWB), and developed a set of unit costs for inpatient and community encounters. We then examined total and mean costs for a range of single and comorbid conditions. Results: We present the unit costs for mental health admissions and mental health community contacts. Our example, which explored the association between comorbidity and total and mean costs, suggested that comorbidly occurring conditions cost more than conditions which occur on their own. Discussion: Our unit costs, and the materials associated with them, have been published in a freely available form governed by a provision termed 'Copyleft'. They provide a valuable resource for researchers wanting to explore economic questions in mental health. Implications for Health Policies: Our unit costs provide an important resource to inform economic debate in mental health in Australia, particularly in the area of priority-setting. In the past, such debate has largely, been based on opinion. Our unit costs provide the underpinning to strengthen the evidence-base of this debate. Implications for Further Research: We would encourage other Australian researchers to make use of our unit costs in order to foster comparability across studies. We would also encourage Australian and international researchers to adopt the 'Copyleft' principle in equivalent circumstances. Furthermore, we suggest that the provision of 'Copyleft'-contingent funding to support the development of enabling resources for researchers should be considered in the planning of future large-scale collaborative survey work, both in Australia and overseas.

Practice challenges at the intersection of child protection and mental health

This paper examines the complexity of collaboration between child protection and mental health services, where a parent has a mental illness and there are protection concerns for children. The paper reports on data from focused in-depth interviews with 36 child protection workers, adult mental health workers and child and youth mental health workers. Data were analysed thematically, using NVivo to facilitate data management and analysis. Two dimensions were identified. The first, the process of collaboration, relates to four factors that assisted the collaborative process: communication, knowledge, role clarity and resources. The second dimension considers the challenges presented to collaborative work when a parent has a mental illness and a child is in need of protection, and identifies issues that are inherent in cases of this kind. Two types of challenge were identified. The first related to characteristics of mental illness, and included the episodic and/or unpredictable nature of mental illness, incorporating information from psychiatric and parenting capacity assessments, and the provision of ongoing support. The second type of challenge concerned the tension between the conflicting needs of parents and their children, and how this was viewed from both the adult mental health and the child protection perspective. Implications for policy and practice are identified in relation to the need for service models that provide ongoing, flexible support that can be intensified or held back as needed.

Stakeholder concerns about Australia's mental health care system

There is growing community and professional concern that the Australian mental health care system requires substantial reform. In response to these concerns, a Senate Select Committee on Mental Health has been commissioned to conduct an inquiry into the provision of mental health services. The current study involved a content analysis of 725 submissions received by the Committee, and highlighted significant areas for reform. People with mental illness face difficulties in accessing mental health care, the care they do receive is of varying quality and poorly coordinated, and necessary services from other sectors, such as housing, are lacking. These problems may be exacerbated for particular groups with complex needs or heightened levels of vulnerability. The system requires reorienting towards the consumers and carers it is designed to serve, and needs stronger governance, higher levels of accountability and improved monitoring of quality. These findings are discussed in the context of the recent acknowledgement of mental health as an issue by the Council of Australian Governments (COAG), which has called for an action plan to be prepared for its consideration by June 2006.

The use of online health techniques to assist with the delivery of specialist paediatric diabetes services in Queensland

We have tested an alternative method of delivering health services to regional areas of Queensland. By integrating telepaediatrics into an existing outreach programme for children with diabetes and endocrine conditions, we were able to reduce travel for specialist hospital staff while maintaining (and sometimes increasing) the contact patients had with the specialist team. In the first 28 months, we facilitated 160 patient consultations and 10 education sessions via videoconference through the telepaediatric service. By the end of the study, site visits were taking place annually and routine videoconference clinics were scheduled quarterly for the review of new patients and follow-up. Telepaediatric services in endocrinology and diabetes were established at three levels: the coordination of routine specialist clinics via videoconference; ad hoc patient consultations for collaborative management during acute presentations and at times of urgent clinical need; and the delivery of education to staff and patients throughout the state. The net result was improved access to specialist services from rural and remote areas of Queensland.

Using the effect size to model change in preference values from descriptive health status

Objectives: This pilot study describes a modelling approach to translate group-level changes in health status into changes in preference values, by using the effect size (ES) to summarize group-level improvement. Methods: ESs are the standardized mean difference between treatment groups in standard deviation (SD) units. Vignettes depicting varying severity in SD decrements on the SF-12 mental health summary scale, with corresponding symptom severity profiles, were valued by a convenience sample of general practitioners (n = 42) using the rating scale (RS) and time trade-off methods. Translation factors between ES differences and change in preference value were developed for five mental disorders, such that ES from published meta-analyses could be transformed into predicted changes in preference values. Results: An ES difference in health status was associated with an average 0.171-0.204 difference in preference value using the RS, and 0.104-0.158 using the time trade off. Conclusions: This observed relationship may be particular to the specific versions of the measures employed in the present study. With further development using different raters and preference measures, this approach may expand the evidence base available for modelling preference change for economic analyses from existing data.

The sense of belonging to a neighbourhood: can it be measured and is it related to health and well being in older women?

This study investigates the sense of belonging to a neighbourhood among 9445 women aged 73-78 years participating in the Australian Longitudinal Study on Women's Health. Thirteen items designed to measure sense of neighbourhood were included in the survey of the older women in 1999. Survey data provided a range of measures of demographic, social and health-related factors to assess scale construct validity. Factor analysis showed that seven of the items loaded on one factor that had good face validity and construct validity as a measure of the sense of neighbourhood. Two of the remaining items related to neighbourhood safety and comprised a factor. A better sense of neighbourhood was associated with better physical and mental health, lower stress, better social support and being physically active. Women who had lived longer at their present address had a better sense of belonging to their neighbourhood, as did women living in non-urban areas and who were better able to manage on their income. Feeling safe in the neighbourhood was least likely in urban areas, increased in rural townships, and was most likely in rural and remote areas. Older women living alone felt less safe, as did women who were less able to manage on their income. This study has identified two sets of items that form valid measures of aspects of the social environment of older women, namely the sense of neighbourhood and feelings of safety. These findings make a contribution to our understanding of the relationship between feelings of belonging to a neighbourhood and health in older women. (C) 2004 Elsevier Ltd. All rights reserved.

Some problems with life event lists and health outcomes

Lists of life events are widely used in health outcomes research. As part of a large cohort study of women's health in Australia, age- and gender-specific life events lists were developed and administered to women in different age groups over time. In this article, we provide empirical evidence that recall of life events is subject to telescoping (i.e., remote events are reported to have occurred more recently) and to mood (women with lower mental health scores report more life events, especially perceived rather than factual events). Nevertheless, even after adjustment for confounders, there is a clear association between poorer physical health and more life events. Therefore, these results demonstrate a continuing need for lists of life events in health research but also highlight the methodological challenges in using them.

Increased use of emergency services by older people after health screening

Background: evaluation of the 'Keep Well At Home' (KWAH) Project in West London indicated that a programme of screening persons aged 75 and over had not reduced rates of emergency attendances and admissions to hospital. However, coverage of the target population was incomplete. The present analysis addresses 'efficacy'-whether individuals who completed the screening protocol as intended did subsequently use Accident & Emergency (A&E) services less often. Methods: the target population was divided into five groups, depending on whether an individual had completed none, one or both phases of screening, and whether deviations from the protocol related to incomplete coverage or refusal to participate further. We ascertained use of emergency services before screening and for up to 3 years afterwards by linkage of records from KWAH to those of local A&E Departments. Patterns of emergency care were examined as crude races and, via proportional hazards models, after adjustment for available confounders. Results: there was an increase of 51% (95% CI 22-86%) in the crude rate of emergency admissions in the year after first-phase screening compared with the 12 months before assessment. This was most obvious in individuals deemed at high risk who also underwent the second-phase assessment (adjusted hazard ratio relative to individuals not 'at risk'= 2.33; 95% CI 1.59-3.42). Conclusions: the available data do not allow us to distinguish between several possible explanations for the paradoxical increase in use of emergency services. However, what seem to be sensible policies do not necessarily have their intended effects when implemented in practice.
