Healthcare utilization and its association with socioeconomic status in China: Evidence from the 2011-2018 China Health and Retirement Longitudinal Study.

INTRODUCTION: Healthcare utilization often favors the higher-socioeconomic status (SES) and having chronic diseases may exacerbate this inequality. This study aims to examine the trends in health service use over time, the effect of SES on healthcare utilization, and the role of chronic diseases in this association. METHODS: Data used in this study were from the China Health and Retirement Longitudinal Study (CHARLS) in 2011, 2013, 2015, and 2018, which is the first nationally representative survey of the middle-aged and older. The sample included people aged 45 years and older who responded to all the waves. A total of 10,922 adults were included in this study. Healthcare utilization was categorized into outpatient and inpatient service use and SES was measured by per-capita household expenditure. A multilevel zero-inflated negative binomial regression model was performed to analyze outpatient and inpatient service use, separately. RESULTS: The rates of outpatient service use in 2011, 2013, 2015, and 2018 were 19.11%, 21.45%, 20.12%, and 16.32%, respectively, while the rates of inpatient service use were 8.40%, 13.04%, 14.17%, and 18.79%, respectively. Compared to individuals in the lowest quintile of per-capita household expenditure, those in higher quintiles had higher odds of outpatient service use (Q2: odds ratio = 1.233, p < 0.0001; Q3: 1.416, p < 0.0001; Q4: 1.408, p < 0.0001; or Q5: 1.439, p < 0.0001) and higher rates of inpatient service use (Q2: incidence rate ratio = 1.273, p < 0.0001; Q3: 1.773, p < 0.0001; Q4: 2.071, p < 0.0001; or Q5: 1.992, p < 0.0001). Additionally, having morbidity generally increased healthcare utilization, but did not play a significant role in moderating the relationship between SES and healthcare utilization. CONCLUSIONS: Healthcare utilization rates were overall low in China, but relatively high for people in higher quintiles of per-capita household expenditure or those with morbidity, compared to their counterparts. Policy actions are required to provide more health education to the public, to further optimize health insurance schemes targeting outpatient services, especially for the low-SES, and to establish new health delivery models for NCD management in the primary health care setting.

Estimating the economic burden of stroke in China: a cost-of-illness study.

OBJECTIVES: Stroke imposes a heavy economic burden and loss of productivity on individuals and society. This study assessed a range of crucial factors, including direct costs and indirect costs, to gauge the economic implications of stroke in China. These outcomes were evaluated with specific reference to the year 2018, using the Chinese yuan (¥) as the unit of measurement and providing the corresponding purchasing power parity dollar ($PPP) currency value. METHODS: A cost-of-illness methodology was used to ascertain the economic implications of stroke in 2018. Within the constraints of this approach, economic costs were defined as 'direct costs' or 'indirect costs'. We estimated direct costs from sample data, the National Health Service Survey and the National Health Account and Health Statistical Yearbook. A human capital method was used to conservatively estimate indirect costs. RESULTS: In 2018, of the economic burden of stroke in China, the direct costs were ¥247.8 billion ($PPP 58.6 billion) and indirect costs were ¥704.4 billion ($PPP 166.5 billion). The curative care expenditure for stroke was ¥193.1 billion ($PPP 45.7 billion), consuming nearly 5.5% of curative expenditure. The cost of stroke treatment relied heavily on public financing, with 58% from social health insurance and 14% from government sources. CONCLUSIONS: A significant economic burden is imposed by stroke on China's economy, and there is a risk of underestimating this burden if indirect costs are not comprehensively considered. The importance of implementing effective preventive measures and screening strategies for stroke, with a particular focus on high-risk populations, is underscored by this study's findings. Such investments in public health have the potential to yield substantial benefits.

Outpatient depression current care expenditure changes in Liaoning Province from 2015 to 2020: a study based on the "system of health accounts 2011".

Introduction: Depression is the leading cause of disability worldwide and has become a health issue of global concern. Based on the "System of Health Accounts 2011" (SHA 2011) for patients with depression, this paper studies the changes in the current curative expenditure (CCE) of outpatient depression in Liaoning Province, China, and provides policy recommendations. Method: A stratified multistage random sample of 56,994 patients with depression included from 1,227 healthcare facilities in Liaoning Province were included. The significance of differences in variables within groups was analyzed by univariate analysis (including descriptive statistics analysis, Mann-Whitney U test and Kruskal-Wallis H test), and factors influencing depression outpatient CCE were analyzed by multiple linear regression analysis and constructing structural equation models (SEM). Results: The CCE of outpatient depression was ranging from CNY 75.57 million to CNY 100.53 million in 2015-2020, with the highest of CNY 100.53 million in 2018, CNY 103.28 million in 2019. Medical expenditures are mainly concentrated in general hospitals and provincial healthcare institutions, accounting for about 90% of all provincial scope expenditures. The multiple regression results show that provincial healthcare institutions, purchase of drug, select medical treatment for depression, general hospitals and urban employees' health insurance are the main influencing factors for depression outpatient CCE. The results of SEM show that insurance status negative impact outpatient expenditure. Conclusion: Health insurance is an important factor in equitable access to healthcare resources for patients, and medication expenditure is the influential factor affecting the high expenditure of outpatient clinics. It is of great importance to reduce the medical burden of patients by increasing the coverage of medical insurance, increasing the proportion of bills that are eligible for reimbursement, and improving the system by guaranteeing the supply of psychotropic medication.

Catastrophic health expenditure and its association with socioeconomic status in China: evidence from the 2011-2018 China Health and Retirement Longitudinal Study.

BACKGROUND: An increase in healthcare utilization in response to universal health coverage may leave massive economic burden on individuals and households. Identifying catastrophic health expenditure helps us understand such burden. This study aims to examine the incidence of catastrophic health expenditure at various thresholds, explore its trend over years, and investigate whether it varies across socioeconomic status (SES). METHODS: Data used in this study were from four waves of the China Health and Retirement Longitudinal Study (CHARLS): 2011, 2013, 2015, and 2018. SES was measured by annual per-capita household expenditure, which was then divided into quintiles (Quintile 1 (Q1): the poorest - Quintile 5 (Q5): the wealthiest). Catastrophic health expenditure was measured at both a fixed threshold (40%) and a set of variable thresholds, where the thresholds for other quintiles were estimated by multiplying 40% by the ratio of average food expenditure in certain quintile to that in the index quintile. Multilevel mixed-effects logistic regression models were used to analyze the determinants of catastrophic health expenditure at various thresholds. RESULTS: A total of 6,953 households were included in our study. The incidence of catastrophic health expenditure varied across the thresholds set. At a fixed threshold, 10.90%, 9.46%, 13.23%, or 24.75% of households incurred catastrophic health expenditure in 2011, 2013, 2015, and 2018, respectively, which were generally lower than those at variable thresholds. Catastrophic health expenditure often decreased from 2011 to 2013, and an increasing trend occurred afterwards. Compared to households in Q5, those in lower quintiles were more likely to suffer catastrophic health expenditure, irrespective of the thresholds set. Similarly, having chronic diseases and healthcare utilization increased the odds of catastrophic health expenditure. CONCLUSIONS: The financial protection against catastrophic health expenditure shocks remains a challenge in China, especially for the low-SES and those with chronic diseases. Concerted efforts are needed to further expand health insurance coverage across breadth, depth, and height, optimize health financing mechanism, redesign cost-sharing arrangements and provider payment methods, and develop more efficient expenditure control strategies.

Efficiency and productivity of health systems in prevention and control of non-communicable diseases in China, 2008-2015.

This article examines the health system performance impact of China's new round of healthcare reform adopted in 2009. Specifically, we evaluated productivity and efficiency of health production pre- and post-reform period, compared the effects across all the 31 provinces of mainland China and identified potential determinants. As a major source of disability and premature mortality in China, non-communicable diseases (NCDs) had been the focus of our analysis, and the period during 2008-2015 was considered to allow enough time for the policy to have meaningful impact on the country's health system. Productivity and efficiency performance were analyzed using a bootstrapping data envelopment analysis (DEA) and the Malmquist productivity index (MPI) techniques, while a Tobit regression technique was used to identify determinants of inefficiency. We find that after the reform efficiency and productivity had declined across large number of provinces. Mean overall technical efficiency (OTE) post 2009 was about 30% lower than the potential maximum capacity, while productivity also fell at a rate of 7.57% per annum. Trends in productivity and efficiency performance were largely linked to patterns of scale of technological change observed during the study period. The findings suggest that efficiency and productivity can be improved through enhancing financial security, optimizing health resource allocation, particularly between human resources for health and hospital beds, and expanding cost-effective technology within the health sector. Better urban planning practices and investment in education were also found to contribute to improved efficiency of NCDs services.

Financing Adolescent Health in China: How Much, Who Pays, and Where It Goes.

PURPOSE: Adolescent health has been gaining increasing attention in the Sustainable Development Goals era. Data on adolescent health financing are essential for evidence-based policy planning and evaluation. Little is known on national expenditure on adolescent health in China. To inform decision-making on national strategies of adolescent health and development, this study estimated expenditure on adolescent health-care utilization in China and identified funding sources and their allocation among different health functions. METHODS: We constructed and implemented an institutional survey and collected primary financial data from health institutions in the nine selected administrative provinces in 2014. We used the collected data to generate estimate of proportion of health spending on adolescent health and its breakdowns by health-care functions, health-care financing schemes, and diseases based on primary diagnosis. We applied the proportion estimates to the 2014 national-level health expenditure data and estimated national-level estimates of spending on adolescent health and breakdowns in aforementioned areas. RESULTS: Spending on adolescents health in 2014 amounted to CNY82.1 billion (USD 13.4 billion) or 2.6% of the total health expenditures in the year. Per adolescent health expenditures was CNY525 (USD 85.5), less than per capita health spending (CNY2349, USD382.4). National spending on adolescent health was 73.1% on curative care and 10.3% on preventive care. Out-of-pocket spending is the major source of adolescent health financing, contributing to 57.9% of total spending on adolescent health. Spending on respiratory, digestive, injury and poisoning, genitourinary diseases, and neoplasms accounted for 59.8% of curative care expenditures on adolescents. CONCLUSIONS: Current financing mechanism on adolescent health stressed on curative care and imposed a large portion of financial burden on households. Future investment on adolescent health shall focus more on preventive care. Financing schemes shall be adjusted so as to reduce household out-of-pocket spending on medical care used by adolescents.

Health system productivity in China: a comparison of pre- and post-2009 healthcare reform.

In 2009, China launched an ambitious health system reform that combined extending social health insurance scheme with improving efficiency, access and quality of care in the country. To assess the impact of the policy on efficiency and productivity change, we investigated the country's health system performance at provincial levels during pre- and post-reform period. Outputs were measured using multiple health outcomes (namely, non-communicable diseases free healthy life years and infant and maternal survival rates), while health expenditure, number of medical personnel and hospital beds per 1000 residents were used as proxy measures for health inputs. Changes in productivity were quantified using a bootstrap Malmquist productivity index (MPI). The analysis focused on the period between 2004 and 2015. This was to capture pre- and post-policy implementation experience and to ensure that enough time was allowed for the policy to work through. Finally, a bootstrap Tobit regression model for panel data was applied to examine the potential effects of contextual factors on productivity change. The result showed that the reform has had negative effects on productivity. Only scale efficiency had improved steadily, but the decline in the scale of technological change observed during the same period meant that the progress in scale efficiency had been masked. Better economic performance (as measured by per capita Gross Domestic Product (GDP)) and higher human resource to capital investment ratio (as measured by density of medical staff per hospital beds) tended to boost productivity growth, while population aging, low educational attainment and higher percentage of out-of-pocket (OOP) payments had adverse effects. Improving health system productivity in China requires improving financial risk protection and maintaining proper balance between human and capital investment in the country.

Technical and scale efficiency of provincial health systems in China: a bootstrapping data envelopment analysis.

OBJECTIVE: With escalating health expenditures and increasing health needs, improving health system performance has become imperative in China and internationally. The objective of this study is to examine the efficiency of China's health system and to understand the underlying causes of the variation in efficiency across provinces. SETTING: A system-wide perspective is adopted, focusing on performance in maternal health, child health and non-communicable diseases (NCDs) in the 31 provinces of mainland China during 2015. METHODS: Analyses were performed using bootstrapping data envelopment technique. Health outcomes were measured by infant survival rates, maternal survival rates and healthy life years calculated only considering NCDs. Health inputs were measured using health expenditure, and density of medical personnel and hospital beds. The model also examined the impact of environmental factors on health system efficiency. RESULTS: Due to wide-spread scale inefficiency in the country, the average bias-corrected overall technical efficiency (OTE) was 0.8022 (95% CI values ranging from 0.7251 to 0.8492). Socioeconomic status, hospitalisation rate and share of out-of-pocket expenditures were significant determinants of OTE. Nearly 60% of the provinces operated at a decreasing return to scale, meaning that a gain in efficiency could be achieved only through downsizing the scale of operation. CONCLUSIONS: Given the pervasive nature of diminishing returns across provinces, health policy makers must explore the optimum operational scale which is people-centred and focused on prevention, rather than on treatment, of diseases. Moreover, due consideration should be afforded to social determinants of health and health financing arrangements to complement health-sector based reforms and meet the ambitious goals of the Healthy China 2030 Plan.

China's Health Expenditure Projections To 2035: Future Trajectory And The Estimated Impact Of Reforms.

To understand the future trajectory of health expenditure in China if current trends continue and the estimated impact of reforms, this study projected health expenditure by disease and function from 2015 to 2035. Current health expenditure in China is projected to grow 8.4 percent annually, on average, in that period. The growth will mainly be driven by rapid increases in services per case of disease and unit cost, which respectively contribute 4.3 and 2.4 percentage points. Circulatory disease expenditure is projected to increase to 23.4 percent of health expenditure by 2035. The biggest challenge facing the Chinese health system is the projected rapid growth in inpatient services. Three percent of gross domestic product could be saved by 2035 by slowing the growth of inpatient service use from 8.2 percent per year in 2016 to 3.5 percent per year in 2035. Health expenditure in 2035 could be reduced by 3.5 percent if the smoking rate were cut in half and by 3.4 percent if the high blood pressure rate were cut by 25 percent. Future action in controlling health expenditure growth in China should focus on the high growth in inpatient services expenditure and interventions to reduce risk factors.
