Political devolution means there are now four National Health Services in the United Kingdom. The health services of England, Scotland, Wales and Northern Ireland are all funded by the UK taxpayer, but have developed different systems of governance and different methods of providing health care. This book examines the impact of devolution in the four countries by studying a number of key performance indicators such as expenditure, staffing levels and waiting times, at three key points – 1996/7, 2002/3 and 2006/7. This is the first time such an analysis has been conducted. Broadly, the report finds striking differences in performance with some UK countries spending more on health care and employing greater numbers of health staff but performing worse in key areas.

This book presents the healthcare reform experiences of six small- to mid-sized, but dynamic, economies spanning the Asia-Pacific, the Middle East and Europe. Usually not given serious consideration in major international comparisons because of their small size, each in fact provides a fascinating case study that illuminates the understanding of the dynamics of healthcare reform. Although dissimilar in historical and cultural backgrounds, they share some important features: all faced very similar pressures for change in the 1970s and 1980s; all considered a very similar range of policy options; and all did not only discuss but actually implemented fundamental changes in their healthcare funding, organization, contracting and governance structures with strikingly different outcomes.

Our evaluation experiences matter – to ourselves and to those we engage with during the evaluation. But to what extent do these evaluations contribute to changing the lives of the people we work with? To what extent are evaluations useful? Can the findings be used and can evaluations be influential in bringing about change? What are the consequences of the decisions we make around an evaluation? Making evaluations matter to the primary intended users of development programmes or initiatives and other key stakeholders is at the heart of this document (Tiré de l'introductron.)

This paper investigates whether individuals exhibit forward looking behavior in their response to the non-linear pricing common in health insurance contracts. Its empirical strategy exploits the fact that employees who join an employer-provided health insurance plan later in the calendar year face the same initial ("spot") price of medical care but a higher expected end-of-year ("future") price than employees who join the same plan earlier in the year. Its results reject the null of completely myopic behavior; medical utilization appears to respond to the future price, with a statistically significant elasticity of medical utilization with respect to the future price of -0.4 to -0.6. To try to quantify the extent of forward looking behavior, it develops a stylized dynamic model of individual behavior and calibrate it using our estimated behavioral response and additional data from the RAND Health Insurance Experiment. Its calibration suggests that the elasticity estimate may be substantially smaller than the one implied by fully forward-looking behavior, yet it is sufficiently high to have an economically significant effect on the response of annual medical utilization to a non-linear health insurance contract. Overall, its results point to the empirical importance of accounting for dynamic incentives in analyses of the impact of health insurance on medical utilization.

Studies of long-term trends in the healthcare financing mix generally focus on a dichotomous concept discerning public from private funding sources. More detailed analyses of the funding mix tend to be restricted to a small number of cases or do rarely examine time trends. This paper enhances the existing body of literature by developing and applying a trichotomous concept for healthcare funding, distinguishing taxes, contributions, and private sources. This includes a new aggregated indicator for the mix of three financing sources and its graphical representation. The study mainly builds upon OECD Health Data 2011. We measure changes in the funding mix since 1972 as its distance from a funding mix that equally draws upon taxes, contributions and private sources. Up to 1980, the OECD healthcare systems move toward ideal-typical financing schemes. Between 1980 and 2000, the funding mix hybridizes mainly driven by privatization processes in NHS and social insurance countries and ongoing switch-over-processes between these two healthcare system types. Since 2000, OECD countries again tend toward ideal-typical funding schemes. This paper uses the framework for institutional change developed by Streeck and Thelen. The quantitative approach highlights changes in terms of displacement, layering, and drift but fails to fully reveal conversion processes. Therefore, further qualitative research is needed to capture not only shifts between the funding sources but also more gradual changes within them. The results show that the back-and-forth development of the trichotomous funding mix challenges assumptions of a universal trend toward hybrid financing structures.

The objective of this paper is to examine the impact of economic evaluation on the reimbursement process for pharmaceuticals. Before the introduction of economic evaluation, a range of arrangements existed across different jurisdictions, varying from reimbursement based on clinical criteria alone and price controls, to a total absence of controls over price or reimbursement. The changes in the structure of reimbursement policies necessary to incorporate economic evaluation have been accomplished without major difficulty in most jurisdictions. However, several methodological differences in international guidelines for economic evaluation exist, only some of which can easily be justified. A number of beneficial changes in reimbursement processes have also been observed, such as a trend towards requiring the measurement of more meaningful clinical endpoints and increased engagement between manufacturers, drug regulators and payers. A consistent finding in studies of reimbursement decisions is that economic considerations have been influential, second only to the strength of the clinical evidence for the drug of interest. The impact of economic evaluation on the allocation of healthcare resources is hard to ascertain because of the difficulties in specifying the counterfactual and the fact that little is known about the extent to which reimbursement decisions actually lead to changes in healthcare practice. However, there is evidence that economic evaluation has assisted price negotiations and enabled reimbursement agencies to target drugs to those patients who will benefit the most. In publicly financed healthcare systems, an evidence-based system of pricing and reimbursement for drugs, considering societal willingness-topay, is a reasonable policy objective to pursue.

This paper investigates the relationship between patients’ primary care costs (consultations, tests, drugs) and their age, gender, deprivation and alternative measures of their morbidity and multimorbidity. Such information is required in order to set capitation fees or budgets for general practices to cover their expenditure on providing primary care services. It is also useful to examine whether practices’ expenditure decisions vary equitably with patient characteristics. Electronic practice record keeping systems mean that there is very rich information on patient diagnoses. But the diagnostic information (with over 9000 possible diagnoses) is too detailed to be practicable for setting capitation fees or practice budgets. Some method of summarizing such information into more manageable measures of morbidity is required. This paper therefore compared the ability of eight measures of patient morbidity and multimorbidity to predict future primary care costs using data on 86,100 individuals in 174 English practices. The measures were derived from four morbidity descriptive systems (17 chronic diseases in the Quality and Outcomes Framework (QOF), 17 chronic diseases in the Charlson scheme, 114 Expanded Diagnosis Clusters (EDCs), and 68 Adjusted Clinical Groups (ACGs)). We found that, in general, for a given disease description system, counts of diseases and sets of disease dummy variables had similar explanatory power and that measures with more categories did better than those with fewer. The EDC measures performed best, followed by the QOF and ACG measures. The Charlson measures had the worst performance but still improved markedly on models containing only age, gender, deprivation and practice effects. Allowing for individual patient morbidity greatly reduced the association of age and cost. There was a pro-deprived bias in expenditure: after allowing for morbidity, patients in areas in th e highest deprivation decile had costs which were 22% higher than those in the lowest deprivation decile. The predictive ability of the best performing morbidity and multimorbidity measures was very good for this type of individual level cross section data, with R2 ranging from 0.31 to 0.46. The statistical method of estimating the relationship between patient characteristics and costs was less important than the type of morbidity measure. Rankings of the morbidity and multimorbidity measures were broadly similar for generalised linear models with log link and Poisson errors and for OLS estimation. It would be currently feasible to combine the results from our study with the data on the number of patients with each QOF disease, which is available on all practices in England, to calculate budgets for general practices to cover their primary care costs.

The English NHS has introduced a system of budgets for general practices covering hospital expenditure for the patients on their lists. This paper models individual expenditure using diagnostic information from previous hospital spells, plus a large set of attributed variables measuring population, general practice, and local hospital characteristics. It shows that, despite the large proportion of zero expenditures and the heavy right tail of expenditures, estimating models of untransformed expenditure via OLS yields better predictions at practice level than one or two part models using OLS with transformed expenditure or Generalised Linear Models. We describe a procedure for setting budgets for general practices which reduces the problem of the lags in the available data. We examine the distinction between need and nonneed variables and the incentive implications of allowing past numbers of hospital encounters to determine practice budgets.

Two ailments limit the effectiveness and threaten the long-term viability of the U.S. Social Security Disability Insurance program (SSDI). First, the program is ineffective in assisting the vast majority of workers with less severe disabilities to reach their employment potential or earn their own way. Second, the program’s expenditures on cash transfers and medical benefits— exceeding $1,500 per U.S. household—are extremely high and growing unsustainably. There is no compelling evidence, however, that the incidence of disabling conditions among the U.S. working age population is rising. This paper discusses the challenges facing the SSDI program, explains how its design has led to rapid and unsustainable growth, considers why past efforts to slow program growth have met with minimal and fleeting success, and outlines three recent proposals that would modify the program to slow growth while potentially improving the employment prospects of workers with disabilities. Because these proposals depart substantially from a program design that has seen little change in half a century, their efficacy is unproven. Additionally, even well-meaning efforts to place the SSDI program on a sustainable trajectory run the risk of creating additional hurdles for claimants who are truly unable to work. Nevertheless, the imminent exhaustion of the SSDI Trust Fund provides an impetus and an opportunity to explore innovative solutions to the longstanding policy challenges posed by the SSDI program.

This paper investigates whether chronic illnesses and injuries have a significant impact on the individual’s performance in the labor market. We use the “Santé et Itinéraires Professionnels” (SIP, “Health and Labor Market Histories”) survey, conducted in France in 2006-2007. We use the propensity score method in order to evaluate the impact of chronic illnesses and accidents on labor market participation and earnings. We find that both health events have a negative effect on professional careers and earnings, and that accidents have a greater impact on women’s earnings.

In Germany as in most countries, risk adjustment up to now has mainly been used between health funds. The aim is to avoid risk selection in order to use competition of health funds to improve efficiency and effectiveness in health care. As a recent development, in 2009 - together with the introduction of the German Health Fund - a morbidity based risk adjustment scheme to distribute resources between the about 180 competing social health funds has been installed. But in the same year, the reform of the remuneration system of physicians in outpatient care depicted a second field of implementation of risk adjustment in the German social health care system introducing some forms of risk adjustment in this context as well. Changes in morbidity of the patient population have to be measured since then and, fulfilling a long-term claim of physicians, morbidity risk was transferred from physicians to statutory health funds. As legal regulations of the reform left space for interpretation, discussions about purposes and potential implementation fields of risk adjustment in the remuneration system for outpatient medical care have been triggered. An important question from an economic point of view is Can the remuneration system for outpatient medical care in Germany be improved by including risk adjustment? This dissertation tries to enrich the discussion about the role of risk adjustment in the German outpatient remuneration system by providing new methodological solutions in the use of a diagnoses based classification system as well as an analysis of the conditions for their use under the specific German conditions.

Several European countries have followed the United States in introducing prospective payment for hospitals with the expectation of achieving cost efficiency gains. This article examines whether theoretical expectations of cost efficiency gains can be empirically confirmed. In contrast to previous studies, the analysis of Switzerland provides a comparison of a retrospective per diem payment system with a prospective global budget and a payment per patient case system. Using a sample of approximately 90 public financed Swiss hospitals during the years 2004 to 2009 and Bayesian inference of a standard and a random parameter frontier model, cost efficiency gains are found, particularly with a payment per patient case system. Payment systems designed to put hospitals at operating risk are more effective than retrospective payment systems. However, hospitals are heterogeneous with respect to their production technologies, making a random parameter frontier model the superior specification for Switzerland.

The organisation of primary eye care services in Europe is not uniform. While in some countries primary eye care is exclusively within the scope of practice of ophthalmologists, other systems rely on a variety of different professions providing essential parts of primary eye and vision health care. The study at hand addresses the question whether costs and outcomes of primary eye care services differ between heterogeneously organised systems. Therefore a special focus on the participation of opticians and optometrists was set. Having similar populations and economic conditions, but differently organised eye care systems, the countries France, Germany and the UK were exemplarily analysed as target countries. Based on an initial description of the different primary eye care systems, a criteria-based evaluation of costs and outcomes was conducted. Information was gained by expert-interviews and a systematic literature search in the Scorpus database alongside with unsystematic Internet searches.

Achieving data and information dissemination without arming anyone is a central task of any entity in charge of collecting data. This article examines the literature on data and statistical confidentiality. Rather than comparing the theoretical properties of specific methods, they emphasize the main themes that emerge from the ongoing discussion among scientists regarding how best to achieve the appropriate balance between data protection, data utility, and data dissemination. They cover the literature on de-identification and rei-dentification methods with emphasis on health care data. The authors also discuss the benefits and limitations for the most common access methods. Although there is abundant theoretical and empirical research, their review reveals lack of consensus on fundamental questions for empirical practice: How to assess disclosure risk, how to choose among disclosure methods, how to assess reidentification risk, and how to measure utility loss.

This paper implements an empirical test for selection into health insurance using changes in coverage induced by the introduction of mandated health insurance in Massachusetts. Our test examines changes in the cost of the newly insured relative to those who were insured prior to the reform. We find that counties with larger increases in insurance coverage over the reform period face the smallest increase in average hospital costs for the insured population, consistent with adverse selection into insurance before the reform. Additional results, incorporating cross-state variation and data on health measures, provide further evidence for adverse selection.

This article provides highlights of the evolution of the health care rationing debate towards a more transparent and open approach involving public participation. Discretionary models that have dominated health sector decision-making are being questioned by different sectors of society. Using data from 442 college students, we explore public’s views on its involvement in health care rationing decisions. Findings suggest that although citizens wish to be consulted, they believe doctors should play the most important role on the rationing decisions. Nonetheless, the confidence in doctors is not independent of the criteria used to support their decisions.

In many countries, sickness absence financed by generous insurance benefits has become an important concern in the policy debate. It turns out that there are strong variations in absence behavior between local geographical areas, and it has been difficult to explain these variations by observable socioeconomic factors. In this paper we investigate whether such variation is related to group effects in the form of social interaction among individuals within neighborhoods. Well-known methodological problems arise when trying to answer such a question. A special feature of our attempt to deal with these problems is that we adopt several alternative approaches to identify group effects. We base the study on a rich set of Swedish panel data, and we find indications of group effects in each one of our approaches.

This paper provides an overview of the growing literature that uses micro-level data from multiple countries to investigate health outcomes, and their link to socioeconomic factors, at older ages. Since the data are at a comparatively young stage, much of the analysis is at an early stage and limited to a handful of countries, with analysis for the US and England being the most common. What is immediately apparent as they get better measures is that health differences between countries amongst those at older ages are real and large. Countries are ranked differently according to whether one considers life-expectancy, prevalence or incidence of one condition or another. And the magnitude of international disparities may vary according to whether measures utilize doctor diagnosed conditions or biomarker-based indicators of disease and poor health. But one key finding emerges – the US ranks poorly on all indicators with the exception of self-reported subjective health status.

The strong link between health insurance and employment in the United States may cause workers to delay retirement until they become eligible for Medicare at age 65. However, some employers extend health insurance benefits to their retirees, and individuals who are eligible for such retiree health benefits need not wait until age 65 to retire with group health coverage. We investigate the impact of retiree health insurance on early retirement using employee-level data from 64 diverse firms that are clients of Towers Watson, a leading benefits consulting firm. We find that retiree health coverage has its strongest effects at ages 62 and 63, resulting in a 3.7 percentage point (21.2 percent) increase in the probability of turnover at age 62 and a 5.1 percentage point (32.2 percent) increase in the probability of turnover at age 63; it has a more modest effects for individuals under the age of 62. A more generous employer contribution of 50 percent or more raises turnover by 1-3 percentage points at ages 56-61, by 5.9 percentage points (33.7 percent) at age 62, and by 6.9 percentage points (43.7 percent) at age 63. Overall, an employer contribution of 50 percent or more reduces the total number of person-years worked between ages 56 and 64 by 9.6 percent relative to no coverage.

Objectives: to investigate, on the basis of the perceptions of general practitioners (GPs) in Belgium, the impact of (early) retirement on subsequent physical and mental health. Method: A cross-sectional survey on the basis of a self-completed anonymous questionnaire sent at random to 120 GPs in Flanders (Belgium) to which 81 responded. Results: According to GPs, the mere fact of retiring early may be a (very) important cause of mental health problems, in particular depressions (due to the disappearance of social networks) and deterioration of cognitive capacities. GPs claim that most physical health problems that appear after retirement, like obesity and cardiovascular diseases, are due to insufficient adaptation (in terms of food consumption and physical activities) of the retired to a new lifestyle.Conclusion: GPs claim that health problems may frequently arise as a consequence of the retirement event. Since the factor s causing these problems point to unhealthy behaviour, there is scope for health improvement: firstly, by stimulating older people to postpone retirement or to continue some professional activities during retirement and secondly, by making them aware of the role of social networks, physical activity and food consumption. At the same time, this would help to control increasing pension and health care expenditures.
