This paper sets road safety education in a health promotion context and describes the application of cost-utility analysis to the economic evaluation of road safety education in New South Wales. The application is tentative and designed to illustrate the advantages of the approach rather than to demonstrate the cost-effectiveness of road safety education.
An economic evaluation of a domiciliary palliative care nursing service operating in NSW assessed the extent to which the program provided more cost-effective care at home, prevented admissions to hospitals and shortened lengths of stay for patients in the terminal stages of cancer. Hospital use (inpatient days) and cost during the patients' last 90 days of life were compared before and after the introduction of the program. There was no statistically significant difference in either and hence no savings to offset the operating costs of the program. However, future savings might be achieved if after-hours access to painkilling drugs is improved.
Economic recession prompts governments and health service ministers to seek increased efficiency in the production of hospital services in order to reconcile increasing demands with scarce resources. As one approach to the problem, the National Health Strategy is recommending pilot schemes, similar to those which have been introduced in both the United Kingdom and the Netherlands, which involve the separation of purchaser from the provider of hospital services. It is argued that such separation, with the introduction of competition between providers of hospital services for contracts placed by publicly funded Area Health Boards, will increase efficiency and accountability in the use of resources. However, this argument ignores the hospital management's ability to keep costs down by altering the quality of hospital care in ways which are difficult to monitor by purchasing agencies. The article considers the effects the introduction of managed competition is likely to have on the quality of hospital services. The outcome is uncertain and competition may improve some dimensions of quality while jeopardizing others. If managed competition is tried in Australia, the opportunity should also be taken to examine its impact on the quality and outcomes of hospital care.
The trend towards community living for people with learning disabilities puts pressure on traditional hierarchical lines of resource management. A sample of 150 community residential facilities is surveyed in order to describe the systems used to manage resources in the community and to assess the impact they have on the quality of service provided. There are marked differences amongst provider agencies in the degree to which responsibility for resource management is devolved to facility managers and this has a direct effect on the quality of care. Residential homes which operate under centralised management systems are more institutional in their care practices and less responsive to individual clients' needs. In contrast, homes in which responsibility is delegated to the facility manager provide a service more in keeping with current philosophies of care. The results of this survey suggest that more responsibility for resource management can be delegated to facility managers without losing control of expenditure and with improvements in the efficiency and effectiveness of care.
The proposals contained in the White Paper 'Working for Patients' have been described as an attempt to introduce competition into a non-competitive situation. Together with the introduction of practice budgets for family practitioners, the granting of self-governing status to NHS hospitals is the principal mechanism by which this aim will be achieved. Very little is known about the effects of competition on the delivery of health care. Evidence from the United Kingdom is non-existent and from the United States of America is inadequate and contradictory. Yet, despite the inconclusive nature of this evidence, the U.K. Government is implementing the most radical reforms of the NHS since its inception without any systematic attempt to monitor the extent to which the reforms achieve the desired ends. In the absence of any systematic evaluation the responsibility for monitoring the effects of self-governing status will fall to the managers and public health specialists in the purchasing authorities. A variety of methods are described which would enable the reforms to be evaluated without holding back their implementation. No radical reform of the NHS can be expected to have an unambiguously beneficial impact on the delivery of health care. If the U.K. Government is genuine in its desire to improve health services, it should be prepared to subject its proposals to the sort of evaluation described in this paper.
Numerous studies have documented the high prevalence of psychological and emotional disorders in patients seen in general medical settings. However, despite the emphasis placed on holistic approaches to nursing care in all professional models of nursing practice, much of this distress is still missed by nursing staff. The Hospital Anxiety and Depression (HAD) scale is an easy-to-use self-administered screening instrument purportedly designed to detect psychological distress amongst hospitalized patients with physical illnesses. On using the HAD scale on patients admitted to a coronary care ward of a district general hospital, 44% were found to be suffering high levels of anxiety or depression. This figure is consistent with the results of similar studies in other cardiac wards and out-patient clinics. In most cases, the levels of distress found were not sufficiently severe to warrant seeking specialist psychiatric support. Instead, there is much that the general nurse can do to alleviate the understandable fears and worries of patients being treated for cardiac disease. However, to respond appropriately, nursing staff must be able to identify psychological distress in patients. The HAD scale, if it can be validated in cardiac in-patient settings, provides an instrument which could easily become part of the routine assessment of patients' nursing needs.

Economic evaluation of health promotion poses few major difficulties when the theoretical approach of the programme and the evaluation of cost and benefits are confined within the context of the individual. Methodological individualism has a long history in economics and the techniques of microeconomics are well suited to the examination of individually focused behaviour change programmes. However, new developments in community health promotion pose special challenges. These programmes have the community, not the individual, as the focus of programme theory and "community' means something completely different from the sum of individuals. Community empowerment and promotion of the community's capacity to deal with health issues are the goals of such programmes. To reflect these notions, sense of community and community competence should be considered as "functionings', an extra-welfarist constituent of well-being. Their inclusion as outcomes of community health promotion requires a shift from individualist utilitarian economics into a communitarian framework which respects the programme's notion of community. If health economics fails to develop new constructs to deal with these new approaches in health promotion, the application of existing techniques to community programmes will mislead health decision makers about their value and potential.
Economic theory typically draws no distinction between preferences and values, assumes that preferences are stable and complete and that all that need be done to elicit them is to ask the right question in the right way. It is argued here that values for some fundamental aspects of life, such as health, are not the same as preferences. The former are less differentiated and require construction and clarification before they can be elicited. The implications of this for health state valuation are discussed.
This paper examines the effect of competition on the behaviour of Australian general practitioners. The paper represents a considerable improvement on the methods of previous studies by using a random effects probit model in a multilevel modelling framework to obtain a more robust estimate of the effect of GP density, by including data on GP and practice characteristics and by using data with the actual GP consultation as the unit of observation which are disaggregated by medical condition. This latter characteristic enables us to test the hypothesis that the effect of competition varies across medical conditions. The main hypothesis tested is that GPs in areas of high competition are more likely to recommend a follow-up consultation compared to GPs in areas of low competition. The results suggest that the density of GPs influences the decision to follow up for one out of the four medical conditions analysed. However, there are other issues to be resolved before such results can be confidently interpreted as evidence of the effect of competition and as evidence of supplier-induced demand.
The increase in community care provision for people with a mental handicap makes an understanding of the attitudes and motivations of staff caring for them an urgent priority. Norma Raynes and colleagues describe a Department of Health-sponsored study which investigated the quality of care delivered in four key sectors of community residential care. Their findings reveal the positive attitudes of staff in all four settings and suggest that local authorities have a potential source of highly motivated recruits among those working in the health, voluntary and private sectors.
