Is Knowing Half the Battle? Behavioral Responses to Risk Information from the National Health Screening Program in Korea
The Asia Health Policy Program is part of the Walter H. Shorenstein Asia-Pacific Research Center
FSI’s researchers assess health and medicine through the lenses of economics, nutrition and politics. They’re studying and influencing public health policies of local and national governments and the roles that corporations and nongovernmental organizations play in providing health care around the world. Scholars look at how governance affects citizens’ health, how children’s health care access affects the aging process and how to improve children’s health in Guatemala and rural China. They want to know what it will take for people to cook more safely and breathe more easily in developing countries.
FSI professors investigate how lifestyles affect health. What good does gardening do for older Americans? What are the benefits of eating organic food or growing genetically modified rice in China? They study cost-effectiveness by examining programs like those aimed at preventing the spread of tuberculosis in Russian prisons. Policies that impact obesity and undernutrition are examined; as are the public health implications of limiting salt in processed foods and the role of smoking among men who work in Chinese factories. FSI health research looks at sweeping domestic policies like the Affordable Care Act and the role of foreign aid in affecting the price of HIV drugs in Africa.
South Korea, the most rapidly aging society in the world, introduced a public long-term care insurance (LTCI) program with universal coverage in 2008. This presentation will begin with the socioeconomic and political context of the introduction of the LTCI and explain the finance and provision of LTCI in Korea, compared to the LTCIs of Germany and Japan. It will provide recent evidence on the performance of the LTCI along with its prospects and lessons for other countries.
This seminar will discuss the marriage distortion and the associated welfare loss caused by the One-Child Policy (OCP) in China. Using the variation in the ethnicity-specific assigned birth quotas and different fertility penalties across provinces over time, we first show that the OCP induced a significantly higher unmarried rate and more interethnic marriages. Using sufficient statistics approach, we then derive a formula for the social welfare loss caused by the OCPinduced lower fertility and marriage distortion, and it only depends on the estimated reducedform elasticities. Our estimates suggest that the associated welfare loss is around 3.7 percent of annual household income, with marriage distortion contributing 30 percent of this. These findings highlight the unintended behavioral responses to public policies and corresponding social consequences.
As 2017 approaches, the Shorenstein Asia-Pacific Research Center documents highlights from the 2015-16 academic year. The latest edition of the Center Overview, entitled "Challenges to Globalization," includes research, people, events and outreach features, and is now available for download online.
China’s recent initiatives to deepen health reform, control antimicrobial resistance, and strengthen primary health services are the topics of ongoing collaborative research by the Asia Health Policy Program (AHPP) at Stanford’s Shorenstein Asia-Pacific Research Center and Chinese counterparts. For example, with generous support from ACON Biotechnology and in partnership with the ACON Biotech Primary Care Research Center in Hangzhou, China, AHPP hosts an annual conference on community health services and primary health care reform in China.
The conference, titled Forum on Community Health Services and Primary Health Care Reform, was held in June at the Stanford Center at Peking University (SCPKU) in Beijing. It featured distinguished policymakers, providers and researchers who discussed a wide-range of topics from China’s emerging “hierarchical medical system” for referring patients to the appropriate level of care (fenji zhenliao), as well as the practice and challenges of innovative approaches to primary care and integrated medical care systems. Yongquan Chen, director of Yong’an City Hospital and representative for the mayor’s office of Sanming, talked about health reforms in Sanming City, Fujian Province, a famous example within China. He discussed the incentives and reasoning behind the reforms, which focus on removing incentives for over-prescription of medications, demonstrating government leadership for comprehensive reforms, consolidating three agencies into one, monitoring implementation and easing tensions between doctors and patients. He pointed out the feasibility and early successes of reform by comparing public hospitals in the city in terms of their revenues and costs, reduced reliance on net revenue from medication sales, and other dimensions of performance. Finally, he addressed reform implementation and future plans on both the hospital's and the government's part.
Xiaofang Han, former director of the Beijing Municipal Development and Reform Commission, shared her personal views on the challenges patients face in navigating China’s health system (kan bing nan) and the need to improve the structure of the delivery system, including a revision to the incentives driving over-prescription in China’s fee-for-service payment system. She emphasized that patients’ distrust of primary care providers can only be overcome by demonstrating improved quality (e.g. with a systematic training program for general practitioners, GPs), and that referral systems should be based on the actual capabilities of the clinicians, not their formal labels. To reach China’s goal of over 80 percent of patients receiving management and first-contact care within their local communities will require improved training and incentive programs for newly-minted MDs, a more flexible physician labor market, and innovations in e-health and patient choice regarding gatekeeping or “contract physician services” (qianyue fuwu).
Guangde County People's Hospital Director Mingliang Xu spoke about practices and exploration of healthcare alliances and initiatives to provide transparent incentives linking medical staff bonuses to metrics of quality. Ping Zhu from Community Healthcare Service Development and Research Center in Ningbo addressed building solid relationships between doctors and residents and providing more patient-centered services.
Professor Yingyao Chen from Fudan University School of Public Health discussed performance assessment of community health service agencies based on his research in Shanghai. He introduced the strengths and weaknesses of the incentives embedded in the assessment system for China’s primary care providers, and concluded with suggestions for future research. Dr. Linlin Hu, associate professor at Peking Union Medical College, discussed China's progress and challenges of providing universal coverage of national essential public health services.
Professor Hufeng Wang of Renmin University of China discussed China’s vision for a “hierarchical medical system”– bearing resemblance to “integrated care,” “managed care,” or NHS-like coordination of primary and specialized care – with examples of pilot reforms from Xiamen, Zhenjiang and Dalian cities. Dr. Zuxun Lu, professor of Tongji Medical College of Huazhong University of Science and Technology, also discussed hierarchical medical systems and declared that China currently had a “discounted gatekeeper system.”
Dr. Yaping Du of Zhejiang University presented his research on mobile technology for management of lipid levels and with the help of a volunteer, demonstrated “Dyslipidemia Manager,” a mobile app-based product for both patients and doctors. Innovative strategies for primary prevention of cardiovascular diseases in low- and middle-income countries were the focus of remarks by Dr. Guanyang Zou from the Institute for Global Health and Development at Queen Margaret University, including its connections to international experiences with China’s current efforts in that area.
In sum, the 2016 Forum elicited lively, evidence-based discussions about the opportunities and challenges in improving primary care and sustaining universal coverage for China. Plans are underway for convening the third annual ACON Biotech-Stanford AHPP Forum on Community Health Services and Primary Health Care Reform in June 2017 at SCPKU. Anyone with original research or innovative experiences with primary care in China may contact Karen Eggleston regarding participation in next year’s Forum.
Wei Huang uses the experience of China's One Child Policy to examine how fertility restrictions affect economic and social outcomes over the lifetime. The One Child Policy imposed a birth quota and heavy penalties for “out-of-plan” births. Using variation in the fertility penalties across provinces over time, He examines how fertility restrictions imposed early in the lives of individuals affected their educational attainment, marriage and fertility decisions, and later life economic outcomes. Exposure to stricter fertility restrictions when young leads to higher education, more white-collar jobs, delayed marriage, and lower fertility. Further consequences include higher household income, consumption, and saving. Finally, exposure to stricter fertility restrictions in early life increases female empowerment as measured by an increase in the fraction of households headed by women, female-oriented consumption and gender-equal opinions. Overall, fertility restrictions imposed when agents are young have powerful effects throughout the life cycle.
Sex differences in mortality (SDIM) vary over time and place as a function of social, health, and medical circumstances. The magnitude of these variations, and their response to large socioeconomic changes, suggest that biological differences cannot fully account for sex differences in survival. We develop a set of empiric observations about SDIM with which any theory will have to contend. We draw on a wide swath of mortality data, including probability of survival to age 70 by county in the United States, the Human Mortality Database data for 18 high-income countries since 1900, and mortality data within and across developing countries over time periods for which reasonably reliable data are available. We show that as societies develop, M/F survival first declines and then increases, a “SDIM transition” embedded within the well-described demographic and epidemiologic transition. After the onset of this transition, cross-sectional variation in SDIM exhibits a consistent pattern of female resilience to mortality under adversity, which strengthens over time.
A long line of research has shown that women live longer than men, yet according to Karen Eggleston, director of the Asia Health Policy Program, and four other Stanford health researchers, mortality rate differences between men and women are much more variable than previously thought, following predictable patterns. Life expectancy differs depending on time, location and socioeconomic circumstance, not on biological factors alone, according to their newly published findings.
The researchers found that women have greater resilience when faced with socioeconomic adversity in a developing country—living nearly 10 years longer than men on average—but this pattern changes as the country evolves. Developed countries typically have smaller gaps in mortality rates between men and women than developing countries do.
Japan and South Korea are outliers, however, with higher mortality rate differences between men and women than is average for developed countries. In addition to the prevalence of male smoking, one possible explanation they draw is the lack of career-related opportunities for women in Japan and South Korea, two countries that have low gender wage equity among Organisation of Economic Co-operation and Development members.
Eggleston, who is part of the core faculty at the Shorenstein Asia-Pacific Research Center, et al. suggested the idea that reducing gender inequality may help narrow the mortality gap: men increase years lived when fewer barriers for women exist, but concluded that their findings supporting this conclusion merit further inquiry.
Their findings were published in the August edition of SSM – Population Health and highlighted in an earlier column on Voxeu.
Exploiting the variation in the amount of subsidy for child health care by municipality, age and time in Japan, this paper examines the effect of patient cost-sharing on child health care utilization. Using longitudinal claims data and triple difference-in-difference framework, we find that reduced cost-sharing significantly increases utilization of outpatient care among children. We further investigate whether these increase in outpatient visits solely reflects moral hazard or increases in beneficial care.
