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.

The relationship between national income and health : a new measure applied to Bangkok

The importance of good health of a population is crucial when determining social welfare. A new health-adjusted national income indicator that explores the relationships between economic growth, health and social welfare in Bangkok, Thailand from 1975 to 1999 is applied. This new approach to social welfare analysis is based on normative social choice theory, cost–benefit and systems analysis and is called (new)3 welfare economics. This paper argues that traditional measures of welfare, such as national income, fail to reflect accurately the impact of health on social welfare.

New money for mental health : will it make things better for rural and remote Australia?

New Australian government funding for the Better Outcomes in Mental Health Care initiative is a significant step forward for mental health, with general practitioners now able to offer direct referrals to psychologists, social workers, occupational therapists and Aboriginal health workers. Incentives for better teamwork between GPs and other mental health professionals have been introduced, but may have unintended consequences, including an exacerbation of workforce shortages in rural and remote areas. Possible solutions to these shortages include rural scholarships for students in the mental health professions; recruitment and retention of students coordinated by university departments of rural health; better access to continuing professional development; and federally funded rural positions and additional financial incentives for rural mental health practitioners.

Why invest in a national public health program for stroke? An example using Australian data to estimate the potential benefits and cost implications

Objectives: Stroke is the world’s second leading cause of death in people aged over 60 years. Approximately 50,000 strokes occur annually in Australia with numbers predicted to increase by about one third over 10-years. Our objectives were to assess the economic implications of a public health program for stroke by: (1) predicting what potential health-gains and cost-offsets could be achieved; and (2) determining the net level of annual investment that would offer value-for-money.

Methods: Lifetime costs and outcomes were calculated for additional cases that would benefit if ‘current practice’ was feasibly improved, estimated for one indicative year using: (i) local epidemiological data, coverage rates and costs; and (ii) pooled effect sizes from systematic reviews.

Interventions: blood pressure lowering; warfarin for atrial fibrillation; increased access to stroke units; intravenous thrombolysis and aspirin for ischemic events; and carotid endarterectomy. Value-for-money threshold: AUD$30,000/DALY recovered.

Results: Improved, prevention and management could prevent about 27,000 (38%) strokes in 2015. In present terms (2004), about 85,000 DALYs and AUD$1.06 billion in lifetime cost-offsets could be recovered. The net level of annual warranted investment was AUD$3.63 billion.

Conclusions: Primary prevention, in particular blood pressure lowering, was most effective. A public health program for stroke
is warranted

Sustainability and health : supporting global ecological integrity in public health

Radical changes in the biosphere and human interaction with the environment are increasingly impacting on the health of populations across the world. Diseases are crossing the species barrier, and spreading rapidly through globalized transport systems. From new patterns of cancer to the threat of global pandemics, it is imperative that public health practitioners acknowledge the interdependence between the sustainability of the environment and the sustainability of the human species.* Why are issues of global and local sustainability of increasing importance to the public's health?* Why do issues of sustainability require new practices within the professions of public health?* How can future and current public health practitioners develop those new practices?Drawing on scientific evidence of global and local environmental changes, Sustainability and Health offers a thorough background and practical solutions to the overlapping issues in environment and health. It examines potential and existing responses to global and local environment and health issues, involving individuals, community, industry and government. The authors introduce a range of emerging conceptual frameworks and theoretical perspectives, link IT and epidemiology and explain how scoping can link program design, delivery, data collection and evaluation in projects from their very beginning. Public health practitioners need to be able to manage health issues that cut across environmental, economic and social systems and to develop the capacity for leadership in facilitating change. Incorporating learning activities, readings, international case studies and an open learning approach, this is a valuable resource for students of public and environmental health, as well as medical, environmental and health science professionals.

Vegetarianism in Seventh-day Adventist home economics classes : an exploration of the issue

The practice of excluding meat from Adventist schools is at odds with the practice of many Adventists, and the Church which, while recommending vegetarianism, does not require it. The study investigates vegetarianism and explores the origin and aims of home economics, education and Seventh-day Adventism. These components were considered according to the three cognitive interests of the philosopher Jurgen Habermas.

The economic analysis of prevention in mental health programs

This article introduces the role economics can play in deciding whether programs designed to prevent mental disorders, which carry large disease and economic burdens, are a worthwhile use of limited healthcare resources. Fortunately, preventive interventions for mental disorders exist; however, which interventions should be financed is a common issue facing decision makers, and economic evaluation can provide answers. Unfortunately, existing economic evaluations of preventive interventions have limited applicability to local healthcare contexts. An approach to priority setting largely based on economic techniques— Assessing Cost-Effectiveness (ACE)—has been developed and used in Australia to answer questions regarding the economic credentials of competing interventions. Eleven preventive interventions for mental disorders and suicide, mostly psychological in nature, have been evaluated using this approach, with many meeting the criteria of good value for money. Interventions targeting the prevention of suicide, adult and childhood depression, childhood anxiety, and early psychosis have particular merit.

Can social dancing prevent falls in older adults? a protocol of the Dance, Aging, Cognition,Economics (DAnCE) fall prevention randomised controlled trial

Background:  Falls are one of the most common health problems among older people and pose a major economic burden on health care systems. Exercise is an accepted stand-alone fall prevention strategy particularly if it is balance training or regular participation in Tai chi. Dance shares the ‘holistic’ approach of practices such as Tai chi. It is a complex sensorimotor rhythmic activity integrating multiple physical, cognitive and social elements. Small-scale randomised controlled trials have indicated that diverse dance styles can improve measures of balance and mobility in older people, but none of these studies has examined the effect of dance on falls or cognition. This study aims to determine whether participation in social dancing: i) reduces the number of falls; and ii) improves cognitive functions associated with fall risk in older people.

Methods/design: A single-blind, cluster randomised controlled trial of 12 months duration will be conducted. Approximately 450 participants will be recruited from 24 self-care retirement villages that house at least 60 residents each in Sydney, Australia. Village residents without cognitive impairment and obtain medical clearance will be eligible. After comprehensive baseline measurements including physiological and cognitive tests and self-completed questionnaires, villages will be randomised to intervention sites (ballroom or folk dance) or to a wait-listed control using a computer randomisation method that minimises imbalances between villages based on two baseline fall risk measures. Main outcome measures are falls, prospectively measured, and the Trail Making cognitive function test. Cost-effectiveness and cost-utility analyses will be performed.

Discussion: This study offers a novel approach to balance training for older people. As a community-based approach to fall prevention, dance offers older people an opportunity for greater social engagement, thereby making a major contribution to healthy ageing. Providing diversity in exercise programs targeting seniors recognises the heterogeneity of multicultural populations and may further increase the number of taking part in exercise.

Primary health-care costs associated with special health care needs up to age 7 years: Australian population-based study.

We studied infants and children with and without special health care needs (SHCN) during the first 8 years of life to compare the (i) types and costs to the government's Medicare system of non-hospital health-care services and prescription medication in each year and (ii) cumulative costs according to persistence of SHCN.
