Risk Adjustment, Risk Sharing and Premium Regulation in Health Insurance Markets: Theory and Practice describes the goals, design and evaluation of health plan payment systems. Part I contains 5 chapters discussing the role of health plan payment in regulated health insurance markets, key aspects of payment design (i.e. risk adjustment, risk sharing and premium regulation), and evaluation methods using administrative data on medical spending. Part II contains 14 chapters describing the health plan payment system in 14 countries and sectors around the world, including Australia, Belgium, Chile, China, Columbia, Germany, Ireland, Israel, the Netherlands, Russia, Switzerland and the United States. Authors discuss the evolution of these payment schemes, along with ongoing reforms and key lessons on the design of health plan payment. Provides a conceptual toolkit that describes the goals, design and evaluation of health plan payment systems in the context of policy paradigms, such as efficiency, affordability, fairness and avoidance of risk selection Brings together international experience from many different countries that apply regulated competition in different ways Delivers a practical toolkit for the evaluation of health plan payment modalities from the standpoint of efficiency and fairness

Reinsurance can complement risk adjustment of health plan payments to improve fit of payments to plan spending at the individual and group level. This paper proposes three improvements in health plan payment systems using reinsurance. First, we base reinsurance payments on spending not accounted for by the risk adjustment system, rather than just high spending. Second, we propose pairing reinsurance for individual-level losses with repayments for individual-level profits. Third, we optimize the weights on the risk adjustors taking account of the presence of reinsurance/repayment. We implement our methodology in data from Germany, The Netherlands and the U.S. Marketplaces, comparing our modified approach to plan payment with risk adjustment as currently practiced in the three settings. The combination of the three improvements yields very substantial improvements in the individual-level fit of payments to plan spending in all three countries.

This publication explores some of the key issues, ranging from interpreting the evidence base to assessing the policy context for, and approaches to, chronic disease management across Europe. Drawing on 12 detailed country reports (available in a second, online volume), the study provides insights into the range of care models and the people involved in delivering these; payment mechanisms and service user access; and challenges faced by countries in the implementation and evaluation of these novel approaches.
