Socioeconomic determinants of rates of consultation in general practice based on fourth national morbidity survey of general practices.

OBJECTIVE: To identify the socioeconomic determinants of consultation rates in general practice. DESIGN: Analysis of data from the fourth national morbidity survey of general practices (MSGP4) including sociodemographic details of individual patients and small area statistics from the 1991 census. Multilevel modelling techniques were used to take account of both individual patient data and small area statistics to relate socioeconomic and health status factors directly to a measure of general practitioner workload. RESULTS: Higher rates of consultations were found in patients who were classified as permanently sick, unemployed (especially those who became unemployed during the study year), living in rented accommodation, from the Indian subcontinent, living with a spouse or partner (women only), children living with two parents (girls only), and living in urban areas, especially those living relatively near the practice. When characteristics of individual patients are known and controlled for the role of "indices of deprivation" is considerably reduced. The effect of individual sociodemographic characteristics were shown to vary between different areas. CONCLUSIONS: Demographic and socioeconomic factors can act as powerful predictors of consultation patterns. Though it will always be necessary to retain some local planning discretion, the sets of coefficients estimated for individual level factors, area level characteristics, and for practice groupings may be sufficient to provide an indicative level of demand for general medical services. Although the problems in using socioeconomic data from individual patients would be substantial, these results are relevant to the development of a resource allocation formula for general practice.

Measurement systems in principle and in practice: the example of nursing workload.

There has been a rapid development of measurement systems in the health services in the United Kingdom (UK) over recent years, not always matched by a thorough understanding of the phenomenon being measured and rarely based on any assessment of reliability or validity. A particularly flagrant example of this process is the development of nursing workload measurement systems (NWMS). The estimates from four NWMS were examined. They were substantially different from each other for no obvious reason, and the difference between any of the estimates and the actual nursing hours worked could not be explained in terms of any other aspect of the nursing process. There is no evidence that the NWMS deployed in the UK are anything more than an expensive numbers game; without this kind of investigation of how they actually work in practice, it would be prudent to be wary about any of the measurement systems which have been proposed. Yet many of the measurement systems used in other sectors of the health service are equally untested.

Allocating resources to health authorities: development of method for small area analysis of use of inpatient services.

Every year about 22 billion pounds is allocated to health authorities for hospital and community services in England. The distribution of most of these funds is based on a formula developed to reflect the population's needs, but the existing formula has been criticised on several grounds. This paper describes the development of a method to determine the health needs for small geographical areas. Data from the hospital episodes statistics and 1991 census together with information on vital statistics and supply of health care facilities were used in the model. Two stage least squares regression was used to identify true indicators of need, and these were entered into a multilevel model to take account of variations in practice in different health authorities. The resulting formula should be more statistically robust and more sensitive to needs than previous approaches.

Allocating resources to health authorities: results and policy implications of small area analysis of use of inpatient services.

A study designed to identify the principal determinants of use of inpatient facilities in NHS hospitals in England used the data and methods outlined in the previous paper. The model for the psychiatric sector contains mortality, self reported morbidity, and social variables indicating deprivation and the level of care at home. The non-acute model contains mortality and several socioeconomic variables. The models lay less weight on age than the current formula, and a national formula based on these models would, in the acute sector, redistribute resources to poorer areas compared with the current formula.

Efficiency and equity implications of the health care reforms.

The purpose of the paper is to reflect on the recent health care reforms in both developed and developing countries, in the light of the evidence that has accumulated over the last few years about the efficiency and equity of different fiscal and organisational arrangements. The scene is set by a brief review of the definitions of efficiency and equity and of the confusions that often arise; and of the problems of making assessments in practice with real data. The evidence about effectiveness, efficiency and equity at the macro level are reviewed: among OECD countries, there is little evidence that variations in the levels and composition of health service expenditure actually affect levels of health; equity in financing and delivery appears to mirror equity in other sectors in the same countries; about the only solid--although rather limp--conclusion which is transferable is that costs can be contained best via global budgeting. The range of reforms in the North is sketched: despite calls to give people 'freedom' to opt out, public finances continues to be preferred among OECD countries; and the evidence that health care markets can actually function is 'weak'. Whilst geographical redistribution of finance has proved to be possible, inequalities in health remain in most countries. But the overwhelming impression is that the quality of the data base for many of these studies is appalling, and the analytice techniques used are simplistic. The move to introduce user charges in the South is discussed. It seems unlikely that they will raise a significant fraction of overall revenue; exemptions intended for the poor do not always work; and other trends are likely to exacerbate the patchy coverage of health care systems in the South. The final section reflects on the pressures for increased accountability. The emphasis on consumerism in the North has led to an increasing number of poorly designed 'patient satisfaction' surveys; in the South, there has been an increasing rhetoric on community participation, but little sign of actual devolution of control. The flavour of the decade is 'outcome measurement' which has been promoted feverish but with little rigour. We must also be concerned that this emphasis will, once again, be hijacked by the most articulate.

Health related quality of life measurement--Euro style.

Several teams are attempting to produce generic health related quality of life measures: none, probably, as ambitious as the EuroQol group who are 'developing a standardised non-disease-specific instrument....with the capacity to generate cross-national comparisons' (EuroQol Group, EuroQol--a new facility for the measurement of health related quality of life, Health Policy, 16 (1990) 199-208). Unfortunately the instrument is flawed both conceptually and in its construction; it is unsurprising, therefore, that the response rates they obtain are so abysmal. Apart from these design faults, the main problem is the quite legitimate refusal of most normal people (respondents) to rate death on the same scale as health states.

The measurement of patient satisfaction.

Many applied health service researchers launch into patient satisfaction surveys without realizing the complexity of the task. This paper identifies the difficulties involved in executing patient satisfaction surveys. The recent revival of interest in 'satisfaction' and disagreements over the meaningfulness of a unitary concept itself are outlined, and the various perspectives and definitions of the components of satisfaction are explored. The difficulties of developing a comprehensive conceptual model are considered, and the issues involved in designing patient satisfaction surveys--and the disasters that occur when these issues are ignored--are then set out. The potential cost-effectiveness of qualitative techniques is discussed, and the paper concludes by discussing how health care management systems could more effectively absorb the findings of patient satisfaction surveys.

Designing a deprivation payment for general practitioners: the UPA(8) wonderland.

OBJECTIVE: To analyse critically the deprived area payment introduced in the new general practitioner contract. The payment formula is based on the Jarman underprivileged area index (UPA(8)) and aims at compensating general practitioners for increases in workload. DESIGN: Evaluation of the deprived area payment against the stated policy objective with a set of criteria for developing resource allocation formulas. MAIN OUTCOME MEASURES: The degree to which the components of the Jarman index predict the workload of general practitioners; whether construction of the index is sensible and comprehensible; and how the formula incorporates the index and is likely to work in practice. RESULTS: The fact that the index relies on census data and the way the weighting was derived means that the formula will not accurately reflect the workload. The use of statistical transformations obscures the original policy intent. There has been no validation to support the application of the index as part of a national policy. The payments are not linked to the quality of service provided and may have the perverse effect of increasing list size. CONCLUSION: The formula used as the basis of the deprived area payments is poorly suited to the policy objective of compensating general practitioners for increases in workload. More research is urgently needed to enable the effect of the payment to be monitored and a more empirically sound set of incentives to be developed.

Allocating resources to health care: is the QALY (Quality Adjusted Life Year) a technical solution to a political problem?

The allocation of health care resources has always been and will remain a contentious issue. Classically, the arguments have been posed in terms of the "need" for health care and/or the "right" to treatment. More recently, there have been attempts to shape the debate in consequentialist terms, by introducing a composite outcome measure. In the United Kingdom, the QALY (Quality Adjusted Life Year) has been promoted enthusiastically. But, like many other such proposals, it is a dodo, and one that is potentially politically dangerous.

Morbidity variation and RAWP.

STUDY OBJECTIVE: Resource allocations from the central government to the English health regions are determined by population levels adjusted by relative standardised mortality ratios (SMRs). The White Paper Working for Patients proposes that allocations should in future be based on capitation adjusted by some other measures of health. The aim of this paper was to investigate the effect of using morbidity data in the weighting algorithm instead of relative SMRs. DESIGN: Morbidity data were obtained from the Health and Lifestyle Survey, 1986. Three different measures of self reported morbidity were used (Long Standing Illness, Any Declared Condition, Any Handicap). Population weightings were calculated by national average bed use for these conditions and again for SMRs. SETTING: This was a national survey using data from all the English health regions. MAIN RESULTS: All three measures of morbidity showed a wider variation between regions than SMRs, and the weighted populations showed a correspondingly wide variation (approximately double that obtained when using SMRs). CONCLUSION: The weighting of populations will be crucial in determining resource allocations to budget holders, whether in the hospital or primary care sector. However without a prior agreement on what counts as "need", the choice of these alternative measures will be arbitrary.

Allocating resources to health care: RAWP (Resources Allocaton Working Party) is dead--long live RAWP.

In England, according to the White Paper, "Working for Patients' the RAWP formula (Resources Allocation Working Party) is to be abandoned. Instead, according to the Working Papers, allocations are to be based on populations weighted for their health and age distributions. In the distributions from the centre to the Regions, SMRs (Standardized Mortality Ratios) are to be retained as a proxy for morbidity albeit with a different weight. This is based, partly, on the analysis carried out by Coopers and Lybrand for the RAWP Review which is shown to be inadequate both conceptually and empirically. The criteria to be used for distributing to Districts and General Practitioners are unclear but "allowance will be made for local and social factors' which suggests that some deprivation index will be incorporated into the process. The most likely choice is the Jarman index and this is shown to be equally inappropriate. The criteria used in allocation, as well as being conceptually coherent and empirically practicable, should be clear and comprehensible to all concerned. The proposals in the White Paper fulfil none of these criteria.

Assumptions of the QALY procedure.

The Quality Adjusted Life Year (QALY) has been proposed as a useful index for those managing the provision of health care because it enables the decision-maker to compare the 'value' of different health care programmes and in a way which, potentially at least, reflects social preferences about the appropriate pattern of provision. The index depends on a combination of a measure of morbidity and the risk of mortality. Methodological debate has tended to concentrate on the technicalities of producing a scale of health; and philosophical argument has concentrated on the ethics of interpersonal comparison. There is little recognition of the fragility of the theoretical assumptions underpinning the proposed combination of morbidity and risk of mortality. The context in which the proposed indices are being developed is examined in Section 2. Whilst most working in the field of health measurement eschew over-simplification, it is clear that the application of micro-economics to management is greatly facilitated if a single index can be agreed. The various approaches to combining morbidity and mortality are described in Section 3. The crucial assumptions concern the measurement and valuation of morbidity; the procedures used for scaling morbidity with mortality; and the role of risk. The nature of the valuations involved are examined in Section 4. It seems unlikely that they could ever be widely acceptable; the combination with death and perfect health poses particular problems; and aggregation across individuals compounds the problem. There are also several technical difficulties of scaling and of allowing for risk which have been discussed elsewhere and so are only considered briefly in Section 5 of this paper.(ABSTRACT TRUNCATED AT 250 WORDS)
