Foreword Health systems everywhere face major challenges–demographic pressures,funding constraints,workforce shortages, rising inequalities, increasingpatients’ expectations to name a few. In this context,international comparisons can serve as a tool to helppolicy makers identify policy options to better addressthese challenges. These comparisons can raise awareness of health systems’ relative strengths andshortcomings, as well as stimulate policy debates that aim to improve health system outcomes. Health systems differ in all aspects of their design: how they are governed, how they are funded, how theygenerate and deploy resources, and how they deliver services. While there is widespread agreement thatthe design of these functions influence health outcomes, limited work has been able to identify how, andto what degree, they do. This report has two main objectives:to identify groups of countries with similar health systemcharacteristics (health system clusters); and to compare and assess performance between and withinhealth system clusters to assess potential links between system characteristics and performance. Thiswork follows and builds on earlier OECD analysis of health system performance carried outin 2009-10. Itdraws heavily on several rounds ofthe OECD survey on health system characteristics carried out by theOECD Health Committee. The analysis highlights that health systems with a different mix of institutions characteristics can achievesimilar levels of efficiency. In other words, there is no best health system institutional set up that will“automatically”result in higher performance. Rather, health systems with similar institutional arrangementscan learn from each other about how specific policy actions can be leveraged to improve healthsystemperformance.
