Winnie Yip

Professor of Health Policy and Economics
Winnie Yip

Winnie Yip is Professor of Health Policy and Economics at the Blavatnik School of Government, the University of Oxford, and Senior Research Fellow of Green Templeton College, Oxford, where she directs the Global Health Policy Program. She is also Adjunct Professor of International Health Policy and Economics at Harvard School of Public Health, where she was a faculty member before moving to Oxford. Winnie received her PhD in Economics from the Massachusetts Institute of Technology and BA in Economics from the University of California, Berkeley, USA.

Winnie’s primary research interests include: 1) the design, implementation and evaluation of health system interventions for improving affordable and equitable access and delivery of quality health care, especially for those most in need and 2) modeling and evaluating the effects of incentives on the behavior of providers (organization and individual) and patients. In addition, she is an expert on China’s health care system. Her works have been funded, among others, by the Bill and Melinda Gates Foundation, the Health Result Innovation Trust Fund (HRITF) of the World Bank, the National Science Foundation (US), the European Union Commission and the Economics and Social Science Research Council (UK).

Winnie is a member of the Institute of Medicine (US) Standing Committee to Support USAID’s Engagement in Health Systems Strengthening, the United Nation Sustainable Development Solutions Network’s Health for All Thematic Group on the post-2015 sustainable development goals and strategies, and the Lancet Global Surgery Commission to promote affordable access and delivery of effective and safe surgical care worldwide. She has served as consultant to the World Bank and the World Health Organization and has extensive executive training experience in Asia, especially China. In addition, she is Associate Editor of Health Economics (Wiley), the Journal of the Economics of Ageing (Elsevier) and Health System and Reform (Taylor & Francis), and an editorial board member of Health Policy, Health Economics, Policy and Law (Cambridge University Press).

Winnie Yip’s research aims to discover and implement sustainable “best practices” in health policy for achieving affordable and equitable access and delivery of quality health care, especially for those most in need. She pursues this through a program that integrates evidence-based health system design, on-the-ground implementation, rigorous evaluation and research findings that are translated into concrete policy actions. Her research studies examine “why” resources are not effectively used within health systems and “how” their use can be improved to enhance benefits for people. Her research approach typically involves large-scale and multi-year social experimentation of innovative health system interventions supported by longitudinal data collection, often in close collaboration with governments and through an inter-disciplinary team, drawing upon the field of economics, political economy, evaluation science, epidemiology, quality of care, marketing science and management.

Based on findings from Winnie’s research team, the government of Ningxia province (a low-income province in the northwest of China with 6.3 million people) has decided to scale up the project’s interventions from two counties and twenty-eight towns (covering about 0.6 million population) to the whole province.

The provider payment interventions that Winnie’s team designed, implemented and evaluated in Ningxia, at both the primary care and county hospital levels, have been highlighted by the National Family Planning and Health Commission (of China) as innovative and feasible for other rural areas of the nation to emulate.

The project’s county hospital intervention, which features a prospectively-set global budget based on the county population’s disease profile combined with pay-for-quality and gatekeeping function, has been further identified as a key model for the nation’s county hospital reform to learn from. The project’s experience has been used as training material for the national county-hospital pilot sites.

Excerpts from the announcements

卫生部通报各地医改工作亮点 (节选)

中华人民共和国国家卫生和计划生育委员会

深化医改以来,各地不断加大探索力度,深入推进医改各项工作。这些探索符合医改方向,成效明显,具有普遍的指导和推广意义。现介绍如下:

三、支付方式改革方面

支付方式改革对控制医药费用、规范医疗行为、推进综合改革等具有重要意义。各地探索了几种不同的支付模式。

宁夏自治区在盐池、海原等县市实施“创新支付制度,提高卫生效益”项目,实施门诊、住院经费包干预付制。包干经费按季度预拨70%给医疗卫生机构,剩余30%根据年度绩效考核结果兑现。

河南省宜阳县按照“一个病种,三套路径”的思路实施新农合综合支付制度改革:A组针对普通症状病人,B组针对有较严重的合并症等病人,C组针对病情严重且复杂的病人。A组和B组实行定价收费,定额支付;C组按实际费用结算,并按比例进行控制。

湖南省推行“限费医疗”,对参合农民在乡镇卫生院的门诊、住院费用设置一定限额。医疗费用在限额内的,参合农民按实付费;超过限额的,参合农民按限额付费,超出部分由新农合全额报销。如蓝山县实行的“10+100”模式,参合农民在县内乡镇卫生院就医,门诊只需自付10元,住院只需自付100—150元,其余费用由新农合基金全额报销。目前正在探索将“限费医疗”模式拓展至县级公立医院。

盐池县医改工作获得国家肯定

近日,在全国卫生计生委主任专题研讨班上,盐池县交流了医改工作经验,这是该县继全国县级公立医院综合改革培训班后的第六次全国性的交流发言。

在全区“创新支付制度,提高卫生效益”试点项目总结大会上,盐池县交流推广了创新支付制度试点项目的好经验、好成效。今年国家卫生计生委及国家人社部领导先后3次专题调研了创新支付制度试点项目的成功经验,再次肯定了盐池县的成功做法。经自治区卫生计生委推荐,盐池县被确立为全国第二批县级公立医院综合改革试点县。

近年来,盐池县实施创新支付制度以来,探索总结出“兼顾供需双方、理性防病就医、突出便民惠民”的盐池综合医改模式。同时,在创新了县、乡、村分级诊疗模式上,适度提高了门诊、住院就诊报销比例,实现了大小病兼顾的目标。乡镇卫生院门诊次均费用下降,县外住院比例逐年下降,医保县外支付资金逐年下降;人均住院报销费用成倍提高,县内住院人次逐年增加,乡 村两级门诊人次成倍增加,乡村两级门诊实现了90%的预期目标。县级医院住院次均费明显低于自治区平均水平。(盐池县卫生局 宋凯萍)
