Promoting physical activity among middle-aged and older adults in health care settings

Physical inactivity continues to be a significant public health issue for middle-aged and older adults. This review focuses on physical activity interventions targeting older adults in health care settings. The literature in this area is limited and the results to date disappointing. Much remains to be done to develop effective interventions targeting older adults, especially those from underserved groups. Attention also needs to be paid to maintenance of initial treatment gains and to linking primary-care-based physical activity interventions to community-based resources. Recognition in the social and behavioral sciences of the importance of social-environmental influences on health and health behaviors mandates both a multidisciplinary and a multilevel intervention approach to the problem of physical inactivity.

The design of hazard risk assessment matrices for ranking occupational health risks and their application in mining and minerals processing

Two hazard risk assessment matrices for the ranking of occupational health risks are described. The qualitative matrix uses qualitative measures of probability and consequence to determine risk assessment codes for hazard-disease combinations. A walk-through survey of an underground metalliferous mine and concentrator is used to demonstrate how the qualitative matrix can be applied to determine priorities for the control of occupational health hazards. The semi-quantitative matrix uses attributable risk as a quantitative measure of probability and uses qualitative measures of consequence. A practical application of this matrix is the determination of occupational health priorities using existing epidemiological studies. Calculated attributable risks from epidemiological studies of hazard-disease combinations in mining and minerals processing are used as examples. These historic response data do not reflect the risks associated with current exposures. A method using current exposure data, known exposure-response relationships and the semi-quantitative matrix is proposed for more accurate and current risk rankings.

Evidence and information for health policy: a decade of change

Over the past decade or so, there has been increasing demand for greater clarity about the major causes of disease and injury, how these differentially affect populations, and how they are changing. In part, this demand has been motivated by resource constraints and a realisation that better health is possible with more informed allocation of resources. At the same time, there has been a change in the way population health and its determinants are quantified, with a much closer integration of the quantitative population sciences (such as epidemiology, demography and health economics) to strengthen and broaden the evidence base for healthcare policy.

Evaluation of the Western Australian Department of Health telehealth project

In 1999, the Department of Health in Western Australia began a telehealth project, which finished in 2004. The 75 videoconferencing sites funded by the project were part of a total state-wide videoconference network of 104 sites. During the period from January 2002 to December 2003, a total of 3266 consultations, case reviews and patient education sessions took place. Clinical use grew to 30% of all telehealth activity. Educational use was approximately 40% (1416 sessions) and management use was about 30% (1031 sessions). The average overhead cost per telehealth session across all regions and usage types was $A192. Meaningful comparisons of the results of the present study with other public health providers were difficult, because many of the available Websites on telehealth were out of date. Despite the successful use of telehealth to deliver clinical services in Western Australia, sustaining the effort in the post-project phase will present significant challenges.

Suicidal ideation and suicide attempts as predictors of mental health service use

Objective: To examine the extent to which suicidal ideation and suicide attempts are predictive of service use. Design and setting: The National Survey of Mental Health and Wellbeing considered service utilisation in relation to self-reported mental health problems. Service utilisation was inquired of in relation to hospital-based care (including both specialist mental health and general care settings), as well as consultations with a range of health professionals (both specialist and non-specialist mental health professionals, including psychiatrists, psychologists and general practitioners) on an outpatient basis. Participants: Secondary analysis of self-report data from 10 641 randomly selected Australian adults who participated in the National Survey of Mental Health and Wellbeing in 1997. The key predictor variables were reported suicidal ideation and suicide attempts over the past 12 months. Main outcome measures: Use of services for mental health problems (past 12 months). Results: When considered in isolation, individuals reporting suicidal ideation were more likely to make use of at least one type of service for mental health problems than non-suicidal individuals (OR, 17.3; 95% Cl, 13.2-22.6), and individuals reporting suicide attempts were even more likely to do so (OR, 32.3; 95% CI, 9.0-115.4). In the case of suicidal ideation, this effect remained significant after controlling for a range of potential confounders. For suicide attempts, the effect of mental health service use was no longer significant after other variables were taken into account. Conclusions: Suicidal individuals are likely to make use of services, and a high proportion of suicides may be preventable through appropriate healthcare system responses.

Perceived need for mental health care: influences of diagnosis, demography and disability

Background. Recent major epidemiological studies have adopted increasingly multidimensional approaches to assessment. Several of these have included some assessment of perceived need for mental health care. The Australian National Survey of Mental Health and Wellbeing, conducted in 1997, included a particularly detailed examination of this construct, with an instrument with demonstrated reliability and validity. Methods. A clustered probability sample of 10641 Australians responded to the field questionnaire for this survey, including questions on perceived need either where there had been service utilization, or where a disorder was detected by administration of sections of the Composite International Diagnostic Interview. The confidentialized unit record file generated from the survey was analysed for determinants of perceived need. Results. Perceived need is increased in females, in people in the middle years of adulthood, and in those who have affective disorders or co-morbidity. Effects of diagnosis and disability can account for most of the differences in gender specific rates. With correction for these effects through regression, there is less perceived need for social interventions and possibly more for counselling in females; disability is confirmed as strongly positively associated with perceived need, as are the presence of affective disorders or co-morbidity. Conclusions. The findings of this study underscore the imperative for mental health services to be attentive and responsive to consumer perceived need. The substantial majority of people who are significantly disabled by mental health problems are among those who see themselves as having such needs.

A randomized controlled trial assessing the health economics of realtime teledermatology compared with conventional care: an urban versus rural perspective

A randomized controlled trial was carried out to measure the cost-effectiveness of realtime teledermatology compared with conventional outpatient dermatology care for patients from urban and rural areas. One urban and one rural health centre were linked to a regional hospital in Northern Ireland by ISDN at 128 kbit/s. Over two years, 274 patients required a hospital outpatient dermatology referral -126 patients (46%) were randomized to a telemedicine consultation and 148 (54%) to a conventional hospital outpatient consultation. Of those seen by telemedicine, 61% were registered with an urban practice, compared with 71% of those seen conventionally. The clinical outcomes of the two types of consultation were similar - almost half the patients were managed after a single consultation with the dermatologist. The observed marginal cost per patient of the initial realtime teledermatology consultation was f52.85 for those in urban areas and f59.93 per patient for those from rural areas. The observed marginal cost of the initial conventional consultation was f47.13 for urban patients and f48.77 for rural patients. The total observed costs of teledermatology were higher than the costs of conventional care in both urban and rural areas, mainly because of the fixed equipment costs. Sensitivity analysis using a real-world scenario showed that in urban areas the average costs of the telemedicine and conventional consultations were about equal, while in rural areas the average cost of the telemedicine consultation was less than that of the conventional consultation.

Mental health telemedicine programmes in Australia

A national survey of mental health telemedicine programmes was conducted and data collected on their catchment areas, organizational structure, equipment, clinical and non-clinical activity, and use by populations who traditionally have been poorly served by mental health services in Australia. Of 25 programmes surveyed, information was obtained for 23. Sixteen programmes had dealt with a total of 526 clients during the preceding three months. Of these, 397 (75%) were resident in rural or remote locations at the time of consultation. Thirty-seven (7%) were Aboriginals or Torres Strait Islanders. Only 19 (4%) were migrants from non-English-speaking backgrounds. The programmes provided both direct clinical and secondary support services. Overall, the number of videoconferencing sessions devoted to clinical activity was low, the average being 123 sessions of direct clinical care per programme per year. Videoconferencing was also used for professional education, peer support., professional supervision, administration and linking families. The results of the study suggest that telehealth can increase access to mental health services for people in rural and remote areas, particularly those who have hitherto been poorly served by mental health services in Australia.

The Mental Health Policy Template: Domains and elements for mental health policy formulation

Mental disorders are a major and rising cause of disease burden in all countries. Even when resources are available, many countries do not have the policy and planning frameworks in place to identify and deliver effective interventions. The World Health Organization (WHO) and the World Bank have emphasized the need for ready access to the basic tools for mental health policy formulation, implementation and sustained development. The Analytical Studies on Mental Health Policy and Service Project, undertaken in 1999-2001 by the International Consortium for Mental Health Services and funded by the Global Forum for Health Research aims to address this need through the development of a template for mental health policy formulation. A mental health policy template has been developed based on an inventory of the key elements of a successful mental health policy. These elements have been validated against a review of international literature, a study of existing mental health policies and the results of extensive consultations with experts in the six WHO regions of the world. The Mental Health Policy Template has been revised and its applicability will be tested in a number of developing countries during 2001-2002. The Mental Health Policy Template and the work of the Consortium for Mental Health Services will be presented and the future role of the template in mental health policy development and reform in developing countries will be discussed.
