中国城镇社会医疗保障改革的理论探索

With its transition to a market-oriented economy, China has gone through significant changes in health care delivery and financing systems in the last three decades. Since 1998, a new public health insurance program for urban employees, called Basic Medical Insurance Program (BMI), has been established. One theme of this reform was to control medical service over-consumption with new cost containment methods. This paper attempts to evaluate the effects of the reformed public health insurance on health care utilization, with in-depth theoretical investigation. We formulate a health care demand model based on the structure of health care delivery and health insurance systems in China. It is assumed in the model that physicians have pure monopoly power in determining patients’ health care utilization. The major inference is that the insurance co-payment mechanism cannot reduce medical service over-utilization effectively without any efforts to control physicians’ behavior. Meanwhile, we use the calibrated simulation to demonstrate our hypothesis in the theoretical model. The main implication is that physicians’ incentive to over utilize medical services for their own benefits is significant and severe in China.      

The relationship between the markets for health insurance and medical malpractice insurance

This article evaluates the interdependence of medical malpractice insurance markets and health insurance markets. Prior research has addressed the performance of these markets, individually, without specifically quantifying the extent to which they are linked. Increasing levels of health insurance losses could increase the scale of potential malpractice claims, boosting medical malpractice losses, or could embody an improvement in medical care quality, which will reduce malpractice losses. Our results for a state panel data set from 2002 to 2009 demonstrate that health insurance losses are negatively related to medical malpractice insurance losses. An additional dollar of health insurance losses is associated with a $0.01–$0.05 reduction in medical malpractice losses. These findings have potentially important implications for assessments of the net cost of health insurance policies.     

Supplementary private health insurance and health care utilization of people aged 50+

Does supplementary private health insurance (PHI) coverage influence health care utilization in countries where the coverage ratio with public health insurance is high? I estimate this effect using the Survey of Health, Ageing and Retirement in Europe. Handling the potential endogeneity of supplementary insurance coverage and the large fraction of zero observations in the utilization models influences the empirical results. I show that the effect of PHI coverage on inpatient and outpatient care utilization is not trivial even in countries with generous public health funding. The main finding is that supplementary PHI coverage increases dental care utilization, but decreases the visits to general practitioners. Private insurance is estimated to have little and insignificant influence on the utilization of inpatient care and outpatient specialist care. The magnitude of the effect of supplementary PHI on health care utilization varies with the characteristics of the health care systems.     

Income-related inequalities of health and health care utilization

By utilizing the China Health and Nutrition Survey (CHNS) data, this paper examines the extent of deviations in terms of horizontal equity in the field of China’s health and medical community, i.e., that those in equal demand ought to be treated equally, and computes the contribution of income in health inequality and utilization inequality of health care. The main conclusions are: There is pro-rich inequality in health and utilization of health care; income contribution to inequality of health care utilization accounts for 0.13–0.2; insurance also enlarges the inequality of health care utilization; health inequality in rural area is larger than that of in urban area; and both rural and urban health inequality are increasing. From 1991 to 2006, income changes in urban districts and rural area account for 7.08% and 13.38% respectively of raising inequality of rural and urban health.     

中国城镇医疗体制改革前后的医疗融资比较

The health financing schemes is the foundation for the nation’s health care system, and the health insurance is a main one of some options for financing health care. This article compares two health care financing schemes in urban areas before and after the health reform, and targets at the impacts facing coverage groups, the financing methods, decision-making power or financial management (i.e. the distribution of responsibility and rights between the central government and local governments), payment arrangement and cost containment of health care financing mechanisms. Prior to reform, the equal access and universal coverage of health care services were implemented through the employment-based health insurance in a state-controlled economy with guaranteed full employment and central control in general. The decentralization reforms of fiscal system and tax sharing reforms disrupts the past economic foundation, the rebuilding health insurance system which still benefits the employed bring the limited coverage. The next trend is to make transition from health insurance covering only part of the employed population to what are in effect national health services covering the whole population in urban areas.      

Public financing of health expenditures,insurance, and health outcomes

The effects of public financing of health expenditures, insurance coverage and other factors on health outcomes are examined within health production models estimated using 1960–1992 data across 20 OECD countries. Mortality rates are found to depend on the mix of health care expenditures and the type of health insurance coverage. Increases in the publicly financed share of health expenditures are associated with increases in mortality rates. Increases in inpatient and ambulatory insurance coverage are associated with reduced mortality. The effects of GDP, health expenditures and age structure on mortality are similar to those in previous studies. Tobacco use, alcohol use, fat consumption, female labour force participation, and education levels are also significantly related to overall mortality rates. Increases in income inequality are associated with lower mortality rates, suggesting that the negative relationship between inequality and health outcomes suggested by some previous studies does not remain when a more complete model is estimated. The result that increases in public financing increase mortality rates is robust to a number of changes in specifications and samples. Thus, as countries increase the level of their health expenditures, they may want to avoid increasing the proportion of their expenditures that are publicly financed.     

The effect of non-employment-based health insurance program on firm's offering of health insurance: Evidence from the social health insurance system in China

To achieve universal health insurance coverage, many developing countries have established a segmented health insurance system, which contains separate programs for workers with formal employment and residents without formal employment. A potential concern with such a segmented system is that the establishment of a non-employment-based insurance program may generate a disincentive for firms to provide health insurance benefits to workers. In this study, we empirically examine this crowd-out effect of a non-employment-based insurance program, the Urban Residents Basic Medical Insurance (URBMI), in China. Exploiting city-by-year variations in the roll-out process of the program and utilizing a unique administrative dataset on Chinese firms, we find that the enactment of URBMI reduced a firm's offering of an employment-based health insurance program by a statistically significant 0.94-1.29 percentage point. This crowd-out effect was stronger among domestic private firms, new firms, and firms that are individual-owned.     

社会医疗保障改革的福利效应:以中国城镇为例

This paper evaluates Chinese public health insurance reform enforced since 1998 in terms of its welfare effects. We evaluate China health insurance reform since 1998 using the China Health and Nutrition Surveys (CHNS) data with relevant econometric models. The results of empirical studies show that the public health insurance status has significant impact on medical service utilization and expenditure. The reform reduces the positive effect of public health insurance on medical service utilization, meaning the utilization gap is narrowed after the reform. However, the empirical studies find that the medical expenditure growth of the sample individuals in urban China has not been controlled after the Basic Medical Insurance (BMI) program even if a new co-payment is enforced. Two main reasons for this failure might be the rising cost of medical service and physician’s severe moral hazard, while both of them come from no managed care mechanism for medical service providers in China.      

Tax subsidies,the rational demand for insurance and the health care crisis

An individual's optimal insurance coverage depends on balancing his gain through avoiding risk against his loss through the distortion of demand. The U.S. tax system subsidizes the purchase of excessive health insurance by excluding employer premium payments from employees' taxable incomes and by permitting the deduction of a portion of individual premiums. The current operational model of demand for health insurance shows that the tax subsidy does substantially increase insurance coverage. Since much of the rise in health care costs can be attributed to the growth of insurance, the tax subsidy is responsible for much of what is widely perceived as a health care crisis.     

US state health expenditure convergence: A revisited analysis

This paper studies the evolution of US state health expenditure for a sample that covers 1966–2014. Our results provide evidence against the existence of a single pattern of behavior of personal health care expenditure across the US states. Rather, we can observe the existence of two statistically different convergence clubs. We cannot find evidence of convergence when we disaggregate health expenditure into its three main payers: Medicare, Medicaid and private health insurance expenditure, whilst we again find evidence of convergence clubs. However, the estimated clubs for Medicaid and private health insurance expenditure are statistically different that estimated for total health expenditure. Consequently, our results offer strong evidence of heterogeneity in the evolution of US health expenditure. The analysis of the forces that drive club creation shows that economic situation and some supply-side factors are important. We can also appreciate that some healthcare outcome variables are only related to private insurance health expenditure. The other health expenditures, thus, show a certain lack of efficiency which may be due to practices that have little benefit for patient health.     

The effect of telehealth insurance mandates on health-care utilization and outcomes

This paper uses panel data techniques to investigate the impact of state mandates to cover telehealth services on private insurance premiums and enrollment, health-care utilization, and health outcomes. There is evidence that telehealth insurance mandates are associated with an increase in primary care, but no significant changes in overall health outcomes. However, there is evidence of a reduction of secondary care and improvement in health outcomes in non-metropolitan areas. The results provide useful information regarding the potential of telehealth to reduce health-care costs as well as to reduce disparities in access to health care and in health outcomes.     

Economic evaluation in health: saving money or improving care?

Summary

Economic evaluation, most commonly in the form of cost-effectiveness analysis, has now become an established tool of overall health financing policy. However, health policy makers choose to use or ignore the accumulated body of economic evidence for a variety of reasons. This policy review takes a step back and looks objectively at the appropriate role and use of cost-effectiveness analysis within the broader context of health system financing, and also discusses a series of technical limitations (and potential solutions) that impact on the generation of a genuinely comparable economic evidence base in health at the population level. While the explicit purpose of economic evaluation is to address the health financing objective of efficiency, the authors conclude that its application can be usefully extended to other health system goals, including financial protection (specification of core public healthcare packages for universal insurance) and equity in financing (assessment of intervention costs and effects by stakeholder or socioeconomic group). In order to contribute to these broader objectives, a sectoral or population-based approach to cost-effectiveness analysis is needed.     

Prenatal care: Mechanisms and impacts on infant health and health care utilization

We estimate that prenatal care has positive impacts on health measured at birth, shifts the distribution of future health care utilization away from inpatient care, and find that some of these impacts likely come from an informational mechanism. We also find well child visits are used in a complementary fashion with emergency department care in the production of infant health, suggesting that factors beyond barriers to access may drive the demand for emergency care. Finally, we find differential impacts of prenatal care across racial groups with evidence that the information mechanism may be particularly important for black mothers.     

医疗保险与城乡反贫困:1989-2006

文章利用中国健康与营养调查(CHNS)数据,估计了1989-2006年医疗保险对中国城乡家庭的反贫困效应。结果发现:发生灾难性卫生支出的城乡家庭比例较高,最穷的群体其医疗费用超过收入的比例增加,医疗保险对减少收入不平等只起到微弱作用。TIP贫困曲线表明,近几年,医疗保险补偿后,城乡患病家庭的贫困并没有减轻,医疗保险在减少贫困上的作用很小。分析贫困特征的多元回归模型显示,家庭成员数量、教育程度、抚养比率、参保人数等都影响了贫困,而条件多元回归模型则显示,医疗保险对贫困的变动没有影响。     

Premium subsidies and demand for private health insurance: results from a regression discontinuity design

This article investigates the impact of a private health insurance (PHI) subsidy on the demand for PHI in the context of the Australian health care system. In particular, we focus on the subpopulation of elderly Australians and exploit discontinuous increases to the universal ‘PHI rebate’ that occur when people turn 65 and 70 years. Using a regression discontinuity design, we find the policy has little effect on take-up of PHI and is best interpreted as a wealth transfer to elderly Australians who already have insurance.     

Analysis on demand‐ and supply‐side responses during the expansion of health insurance coverage in Vietnam: Challenges and policy implications toward universal health coverage

This study examines how the demand and supply of healthcare services have responded to the expansion of health insurance coverage in Vietnam by using biyearly provincial panel data from 2006 to 2014. The results of our analysis indicate significant progress towards universal health coverage (UHC) in Vietnam, with the expansion of health insurance coverage being accompanied by increases in admissions and inpatient days. However, some concerns remain. Our findings show a positive response of supply capacity only in terms of doctors and nurses at higher‐level hospitals (provincial hospitals), and none in other relevant aspects. Moreover, we find no positive response of the number of outpatient visits. Another concern is the issue of financial protection. The decline in out‐of‐pocket payments is not significant throughout our observation period, suggesting that lowering the cost of healthcare is not straightforward and that the expansion of health insurance coverage alone cannot achieve this. We believe that the Vietnamese experience has valuable implications for other emerging and developing countries, considering that the expansion of health insurance coverage is likely to increase utilization of healthcare services significantly and that the supply side needs to be prepared for the increase.     

我国健康保险有效需求的实证分析

有效保险需求是在当前特定时期内,在一定保险价格、一定购买力条件下现实的保险需求,是保险公司真正面对的业务来源。本文使用最近几年健康保险保费收入、城镇居民可支配收入、城镇基本医疗保险基金总收入及居民医疗保健支出等数据,通过建立回归模型对健康保险有效需求进行分析。结果显示：居民购买力和医疗费用的增长对我国健康保险的有效需求有显著影响,社会保险并未对商业健康保险产生替代作用,相反与健康保险保费收入同向增长。     

Cost of health care and quality outcomes of patients at nurse-managed clinics

Lack of health insurance is a critical factor in access to appropriate health services and is directly associated with poor functioning, increased morbidity and mortality, lack of continuity of care, and rising health care costs. Nurse-managed clinics (NMCs) can serve as an important safety net in the health care delivery system by offering needed health services to the poor and underinsured populations. Indicators of quality of care at NMCs include removing barriers to care, improving health care access, and developing therapeutic relationships with nurse practitioners. Much evidence also exists that nurse-managed clinics improve the use of preventative services, aid in the promotion of health, compliance of treatment and patient satisfaction, and reduce emergency room visits and rehospitalizations. One of the consistent themes in this review is the need for patient volume enhancement and the importance of reimbursement through Medicaid and third-party payers if nurse-managed clinics are to remain viable.     

Socio-economic evaluation of mental health as a basis for financing health care in Sweden

The objective of this paper is to examine hypotheses about the relationships between socio-economic factors, risk factors in working life, and the occurrence of mental illness, together with the degree of quality of life and consumption of health care, costs for health care, and costs for social insurance. This is a prospective and longitudinal study of 1,347 individuals of an active working age, 18–64 years, who have been on sick leave for more than 30 days. The group is characterized by the prevalence of risk factors in their work environment and welfare losses, such as multiple health problems, poor quality of life, inability to work, and dependency on society's support from health care and social insurance. The costs for health care were just over 2.8 million SEK, or 30 percent higher for those with psychological distress as compared to the group without. The payments from social insurance also increased by approximately 15 percent. The relatively greater weighting of health care costs and sickness cash benefits were motivating factors to study whether this group had an optimal amount and quality of health care, or if the resources available for health care should be distributed in another way that better satisfies the needs of the group.
