Article
Full-text available
Background: The implications of competition among hospitals on care quality have been the subject of considerable debate. On one hand, economic theory suggests that when prices are regulated, quality will be increased in competitive markets. On the other hand, hospital mergers have been justified by the need to exploit cost advantages, and by evid...

Background As part of the EU funded BRIDGE Health project, 23 headline indicators for assessing and comparing the performance of public health systems were proposed. They were shortlisted out of the currently existing and often overlapping pool of over 2000 health system performance assessment (HSPA) indicators. In this qualitative study, we explor...

Introduction: Long-term care (LTC) is organized in a fragmented manner. Payer agencies (PA) receive LTC funds from the agency collecting funds, and commission services. Yet, distributional equity (DE) across PAs, a precondition to geographical equity of access to LTC, has received limited attention. We conceptualize that LTC systems promote DE when...

Reducing repeated hospitalizations of patients with chronic conditions is a policy objective for improving system efficiency. We test the hypothesis that the risk of readmission is associated with the timing and intensity of primary care follow-up after discharge, focusing on patients hospitalized for heart failure in France. We propose a discrete-...

Better monitoring of patients in primary care setting is often considered to be a solution for reducing avoidable hospitalisations and readmissions. In this paper we test the hypothesis that the risk of readmission is associated with the timing and intensity of primary care follow-up, with a focus on consultations with a generalist (GP) after disch...

Variations in health care use within a country are complicated. In some cases they may reflect differences in health needs, in patient preferences or in the diffusion of a therapeutic innovation; in others they may not. There is evidence that some of the observed variations are unwarranted, signalling under- or over-provision of health services, or...

In France, a DRG-based payment system was introduced in 2004/2005 for funding acute services in all hospitals with the objectives of improving hospital efficiency, transparency and fairness in payments to public and private hospitals. Despite the initial consensus on the necessity of the reform, providers have become increasingly critical of the sy...

Diagnosis related groups (DRGs) were originally developed in the 1970s by researchers at Yale University. Their aim was to define “hospital products” and to measure what hospitals actually do. Medicare in the United States soon realised the potential of DRGs for paying hospitals for their work and introduced the first DRG based payment system in 19...

The activity-based funding (T2A) is used since 2004-2005, for financing acute hospital care in public and private hospitals with an objective to improve the efficiency of individual providers and the hospital sector as a whole. To date, however, the impact of T2A on hospital activity, productivity and quality of care has only been partially evaluat...

A standard doctor visit or routine check-up can be essential for maintaining good health. People who have regular checkups may identify health issues well before any symptoms show up and receive the treatment for reducing onset and complications. Many of the costly and disabling conditions can be prevented through early detection. Therefore, improv...

Industrialised countries face similar challenges for improving the performance of their health system. Nevertheless, the nature and intensity of the reforms required are largely determined by each country’s basic social security model. Most reforms in Beveridge-type systems have sought to increase choice and reduce waiting times while those in majo...

This study contributes to the literature on the link between hospital volume and outcomes of care by exploiting for the first time the French hospital data at a national level. Using multilevel models, we test the strength and the shape of the relationship for eight conditions. The results suggest that activity volumes may be a good measure of regu...
Conference Paper
Rational: In Europe it is well documented that significant inequalities exist in the use of health-care services across socio-economic groups. There is also evidence that the degree of this inequality in access to care varies significantly from one country to other. Nevertheless, in previous work little attention is paid to the role of the health-c...
