Abstract: We use a formal model to examine the implications of endogenous managerial effort for the interpretation and estimation of efficiency in health care organisations. The model is applied to investigate the doubling of the cost of administering primary care in England in real terms between 1989/1990 and 1994/1995. The main cost determinant was the number of general practitioners (GPs), and there were economies of scale but not of scope. Fund-holding had a positive but small effect on administrative costs, so that the recent abolition of fund-holding may do little to reduce primary care administrative costs. After allowing for changes in the numbers of primary care practitioners, the quality of primary care and the extent of fund-holding, most of the increase in costs was unexplained, and may reflect additional but unmeasured increases in the administrative burden associated with the 1990 reforms. There was little variation in relative efficiency across areas.

Abstract: We examine how public sector third-party purchasers and hospitals negotiate quality targets when a fixed proportion of hospital revenue is required to be linked to quality. We develop a bargaining model linking the number of quality targets to purchaser and hospital characteristics. Using data extracted from 153 contracts for acute hospital services in England in 2010/2011, we find that the number of quality targets is associated with the purchaser's population health and its budget, the hospital type, whether the purchaser delegated negotiation to an agency, and the quality targets imposed by the supervising regional health authority.

Abstract: Many countries use financial incentive programs to attract physicians to work in rural areas. This paper examines the effectiveness of a policy reform in Australia that made some locations newly eligible for financial incentives and increased incentives for locations already eligible. The analysis uses panel data (2008-2014) on all Australian general practitioners (GPs) aggregated to small areas. We use a difference-in-differences approach to examine if the policy change affected GP entry or exit to the 755 newly eligible locations and the 787 always eligible locations relative to 2249 locations which were never eligible. The policy change increased the entry of newly-qualified GPs to newly eligible locations but had no effect on the entry and exit of other GPs. Our results suggest that location incentives should be targeted at newly qualified GPs.

Abstract: We test the relative income hypothesis that an in idual's health depends on the distribution of income in a reference group, as well as on the income of the in idual. We use data on 231 208 in iduals in Great Britain from 19 rounds of the General Household Survey between 1979 and 2000. Results are insensitive to the measure of self-assessed health used but the sign and significance of the effect of relative income depend on the reference group (national or regional) and the measure of relative income (Gini coefficient, absolute or proportional difference from the reference group mean, Yitzhaki absolute and proportional relative deprivation and affluence). Only one model (relative deprivation measured as income proportional to regional mean income) performs better than the model without relative income and has a positive estimated effect of absolute income on health. In this model the increase in the probability of good health from a ceteris paribus reduction in relative deprivation from the upper quartile to zero is 0.010, whereas an increase in income from the lower to the upper quartile increases the probability by 0.056. While our results provide only very weak support for the relative deprivation hypothesis, the inevitable correlation of measures of in idual income and relative deprivation measured by comparing income and incomes in a reference group makes identification of the separate effects of income and relative deprivation problematic.

Abstract: To estimate the impact of a national primary care pay for performance scheme, the Quality and Outcomes Framework in England, on emergency hospital admissions for ambulatory care sensitive conditions (ACSCs). Controlled longitudinal study. English National Health Service between 1998/99 and 2010/11. Populations registered with each of 6975 family practices in England. Year specific differences between trend adjusted emergency hospital admission rates for incentivised ACSCs before and after the introduction of the Quality and Outcomes Framework scheme and two comparators: non-incentivised ACSCs and non-ACSCs. Incentivised ACSC admissions showed a relative reduction of 2.7% (95% confidence interval 1.6% to 3.8%) in the first year of the Quality and Outcomes Framework compared with ACSCs that were not incentivised. This increased to a relative reduction of 8.0% (6.9% to 9.1%) in 2010/11. Compared with conditions that are not regarded as being influenced by the quality of ambulatory care (non-ACSCs), incentivised ACSCs also showed a relative reduction in rates of emergency admissions of 2.8% (2.0% to 3.6%) in the first year increasing to 10.9% (10.1% to 11.7%) by 2010/11. The introduction of a major national pay for performance scheme for primary care in England was associated with a decrease in emergency admissions for incentivised conditions compared with conditions that were not incentivised. Contemporaneous health service changes seem unlikely to have caused the sharp change in the trajectory of incentivised ACSC admissions immediately after the introduction of the Quality and Outcomes Framework. The decrease seems larger than would be expected from the changes in the process measures that were incentivised, suggesting that the pay for performance scheme may have had impacts on quality of care beyond the directly incentivised activities.

Abstract: Achieving equity in healthcare, in the form of equal use for equal need, is an objective of many healthcare systems. The evaluation of equity requires value judgements as well as analysis of data. Previous studies are limited in the range of health and supply variables considered but show a pro-poor distribution of general practitioner consultations and inpatient services and a pro-rich distribution of outpatient visits. We investigate inequality and inequity in the use of general practitioner consultations, outpatient visits, day cases and inpatient stays in England with a unique linked data set that combines rich information on the health of in iduals and their socio-economic circumstances with information on local supply factors. The data are for the period 1998-2000, just prior to the introduction of a set of National Health Service (NHS) reforms with potential equity implications. We find inequalities in utilisation with respect to income, ethnicity, employment status and education. Low-income in iduals and ethnic minorities have lower use of secondary care despite having higher use of primary care. Ward level supply factors affect utilisation and are important for investigating health care inequality. Our results show some evidence of inequity prior to the reforms and provide a baseline against which the effects of the new NHS can be assessed.

Abstract: Objectives: To compare geographical inequality in the distribution of general practitioners (GPs), other resources and mortality around 1995 in England and Wales to measure trends between 1974 and 1995 in inequality of GP distribution to examine the implications of different need adjustments and inequality measures on the degree of geographic inequality and to analyse the impact of policies (increased supply, area inducements and entry regulation) on inequality. Methods: Measurement of relative inequality (decile ratio, Gini coefficient, Atkinson index) and absolute inequality (standard deviation) in the ratio of GPs to need-adjusted population in former Family Practitioner Committee/Family Health Services Authority areas each year from 1974 to 1995 and relative inequality across areas in the distributions of income, other resources and standardised mortality ratios (SMRs) around 1995. Regression of 1995 GP opulation ratios on 1974 ratios. Application of equalising net advantages location model to GP distribution. Results: Inequality in the distribution of GPs in 1995 was less than inequality in other primary care resources, but greater than inequalities in disposable income, SMRs, primary school expenditure, and hospital and community health services expenditure. The decile ratio shows little change between 1974 and 1995. Gini and Atkinson inequality indices indicate some reduction in inequality between 1974 and 1980, but little change thereafter. The standard deviation of need-adjusted provision increased over the period. Areas that had the lowest GP provision in 1974 tended to have the lowest in 1995. Conclusions: The choice between relative and absolute inequality measures and, to a lesser extent, the method of adjusting for need affect conclusions about the trend in inequality. Both types of measure and most need adjustments suggest that the policies adopted did not lead to a reduction in inequality over the period. Interactions between policies may reduce their overall effectiveness.

Abstract: We construct a model of the admission process for patients from general practices for elective surgery in the UK National Health Service. Public patients face a positive waiting time, but a zero money price. Fundholding practices faced a positive money price for each patient admitted. The model is tested with data on general practice admission rates for cataract procedures in an English Health Authority. Admission rates are negatively related to waiting times and distance to hospital. Practices respond to financial incentives as predicted by the model: fundholding practices have lower admission rates than non-fundholders and respond differently to changes in waiting times and patient characteristics.

Abstract: We analyse the determinants of annual net income and wages (net income/hours) of general practitioners (GPs) using data for 2271 GPs in England recorded during Autumn 2008. The average GP had an annual net income of £97,500 and worked 43 h per week. The mean wage was £51 per h. Net income and wages depended on gender, experience, list size, partnership size, whether or not the GP worked in a dispensing practice, whether they were salaried of self-employed, whether they worked in a practice with a nationally or locally negotiated contract, and the characteristics of the local population (proportion from ethnic minorities, rurality, and income deprivation). The findings have implications for pay discrimination by GP gender and ethnicity, GP preferences for partnership size, incentives for competition for patients, and compensating differentials for local population characteristics. They also shed light on the attractiveness to GPs in England of locally negotiated (personal medical services) versus nationally negotiated (general medical services) contracts.

Abstract: To measure and decompose income related inequalities in self assessed health in England, Scotland, and Wales, 1979-1995. The relation between in idual health and a non-linear transformation of equivalised income, allowing for sex, age, country, and year effects, was estimated by multiple regression. The share of health attributable to transformed income and the Gini coefficient for transformed income were calculated. Inequality in health was measured by the partial concentration index, which is the product of the Gini coefficient and the share of health attributable to transformed income. Representative annual s les of the adult population living in private households in Great Britain 1979-1995. The total analysed s le was 299,968 people. Pro-rich health inequality was largest in Wales and smallest in England over the period because the effect of increased income on health was greatest in Wales and least in England. In all three countries, pro-rich health inequality increased throughout the period. In the early 1980s this was primarily attributable to increases in income inequality. Thereafter the increased share of health attributable to income was the principal cause. Reductions in pro-rich health inequality can be achieved by reducing income inequality, reducing the effect of income on health, or both.

Abstract: Objectives: To explore variations in general practice admission rates, comparing standardisation by regression with direct standardisation of the data to identify explained and unexplained variation. Methods: Data from hospital episode statistics and the attribution dataset on 8048 cataract admissions from 109 practices in an English health district (North Yorkshire) between 1995 and 1998. Multiple regression was used to estimate the effect of practice characteristics, socio-economic factors, waiting times and distance on practice admission rates. Rankings of practices by the residuals from the regression were compared with rankings by directly standardised admission rates. Results: The regression model yielded intuitively plausible results and explained 35% of the cross-practice variation in directly standardised admission rates. Standardisation by regression, compared with direct standardisation, made as least as much difference to the ranking of practices as direct standardisation compared with crude admission rates. Regression standardisation suggested that 10 practices not identified as 'unusual' by comparison of their rates to the district mean were in fact 'unusual', and that six practices identified as unusual by comparison with the district mean were not unusual once allowing for the explanatory factors used in the regression model. Conclusions: Given the increasing importance of systematic performance assessment to support quality improvement, care must be taken when interpreting variations in health care activity even after conventional standardisation of the data. If significant variations are detected, regression analysis can assist in explaining some of it, which is the starting point in informing discussions about whether variations are justified or unjustified.

Abstract: Many health-care systems allocate funding according to measures of need. The utilisation approach for measuring need rests on the assumptions that use of health care is determined by demand and supply and that need is an important element of demand. By estimating utilisation models which allow for supply it is possible to isolate the socio-economic and health characteristics which affect demand. A subset of these variables can then be identified by a combination of judgement and further analysis as needs variables to inform funding allocations. We estimate utilisation models using newly assembled data on admissions to acute hospitals, measures of supply, morbidity and socio-economic characteristics for 8414 small geographical areas in England. We make a number of methodological innovations including deriving additional measures of specific morbidities at small area level from in idual level survey data. We compare models with different specifications for the effect of waiting times and provider characteristics, with total, planned and unplanned hospital admissions, and estimated at small area (ward) and primary care organisation (general practice) level. After allowing for waiting times, distance, capacity and the availability of private health care, measures of mortality, self-reported morbidity, low education and low income increase the use of health care. We find evidence of horizontal inequity with respect to ethnicity and employment and suggest a method for reducing its effects when deriving a needs-based allocation formula.

Abstract: Most national surveys of health care utilisation capture only self-reported measures of morbidity. If self-reported morbidity is measured with error, then the results of applied work may be misleading. In this paper we propose a model of the relationship between morbidity and health service utilisation which allows for reporting errors and simultaneity. Errors in self-reported morbidity are expressed as a function of person-specific reporting thresholds and recent contact with health services, arising because of better self-evaluation of current health status or a desire to justify consumption of a publicly-provided good. We demonstrate the bias in ignoring the potential problems of reporting errors and simultaneity for a variety of special cases, but in the general case the biases are of ambiguous sign. The empirical nature of these biases is investigated using limiting long-standing illness (LLI) and recent contact with a General Practitioner (GP) in two waves of The UK Health and Lifestyle Survey. Biomedical measures of functioning are used as objective indicators of health status. We find evidence of substantial and significant differences between in iduals in reporting thresholds and some evidence that the reporting of LLI may depend on recent visits to a GP. Adjustments for these biases significantly increase the estimated effect of morbidity on utilisation.
