Measuring the continuing care needs of inpatients in rural China.

BACKGROUND: International experience shows that the suitability of a high-performance healthcare system for its given purposes is reflected in its ability to provide a continuum of services that match the changing health status of the given population. Although many low- and middle-income countries have sought to bring movement away from hospital-centered and towards patient-centered healthcare, such efforts have often had poor results, and one of the major reasons for this is the inability to accurately identify which inpatients need continuing care and what kind of continuing of care is needed. OBJECTIVES: To measure and assess the continuing care needs of discharged patients and its influencing factors in rural China. METHODS: Data were obtained from the hospital database of Medical Center M in County Z from May to July 2022. County Z is a county of 1 million people in central China. The database includes basic patient information, disease-related information, and information on readiness for hospital discharge. Factors related to the need for continuing care were included in the analysis. The Readiness for Hospital Discharge Scale was used to assess the need for continuing care. The statistical data are expressed in terms of both frequency and composition ratio. Finally, linear regression was used to analyze the factors influencing the need for continuing care. RESULTS: The analysis included a total of 3,791 patients, 123 of whom (3.25%) had continuing nursing needs. The need of continuing nursing was related to patients' age group, mode of admission, occupation and major diagnostic categories (P < 0.05). CONCLUSIONS: Developing continuing care is an important initiative for bridging the fragmentation of health services, and an appropriate supply system for continuing care, interconnected with inpatient services, should be established in rural areas in China as soon as possible. And provide more appropriate care for patients in need.

Impact of Diagnosis-Related-Group (DRG) payment on variation in hospitalization expenditure: evidence from China.

BACKGROUND: Diagnosis-Related-Group (DRG) payment is considered a crucial means of addressing the rapid increases of medical cost and variation in cost. This paper analyzes the impact of DRG payment on variation in hospitalization expenditure in China. METHOD: Patients with chronic obstructive pulmonary disease (COPD), acute myocardial infarction (AMI) and cerebral infarction (CI) in a Chinese City Z were selected. Patients in the fee-for-service (FFS) payment group and the DRG payment group were used as the control group and intervention group, respectively, and propensity-score-matching (PSM) was conducted. Interquartile distance (IQR), standard deviation (SD) and concentration index were used to analyze variation and trends in terms of hospitalization expenditure across the different groups. RESULTS: After DRG payment reform, the SD of hospitalization expenditure in respect of the COPD, AMI and CI patients in City Z decreased by 11,094, 4,833 and 4,987 CNY, respectively. The concentration indices of hospitalization expenditures for three diseases are all below 0 (statistically significant), with the absolute value tending to increase year by year. CONCLUSION: DRG payment can be seen to guide medical service providers to provide effective treatment that can improve the consistency of medical care services, bringing the cost of medical care closer to its true clinical value.

Can a global budget improve health care efficiency? Experimental evidence from China.

Health care in China suffers from substantial allocative inefficiency in the delivery system and technical inefficiency within hospitals. To ameliorate this problem in rural areas, the Analysis of Provider Payment Reforms on Advancing China's Health (APPROACH) project shifted the payment method of China's rural health insurance scheme for county hospitals from fee-for-service to a novel global budget. In particular, APPROACH global budget incentivized system-level allocative efficiency by reimbursing county hospitals at higher tariffs for gatekeeping and averting out-of-county (OOC) admissions among local patients they could treat. APPROACH conducted a large-scale randomized controlled trial of the global budget in 56 counties (22 million enrollees) of Guizhou province during 2016-2017. Applying randomization inference to claims data, we find a significant shift of inpatient utilization and expenditure from OOC hospitals to county hospitals. At county hospitals, average expenditure per admission and length of stay decreased, though not significantly. Effects on readmissions show no clear sign of compromised quality. We further find limited effect heterogeneity with respect to treatment and hospital characteristics. Overall, APPROACH global budget may offer a framework for improving health care efficiency without sacrificing quality.

Trends in avoidable hospitalizations in a developed City in eastern China: 2015 to 2018.

OBJECTIVE: This study aimed to measure the avoidable hospitalization rate and the treatment cost per hospitalization in large cities of eastern China. METHODS: In this study, the hospital discharge data of all inpatients in the city from 2015 to 2018 were collected. In accordance with the organization for Economic Cooperation and Development (OECD) definition of avoidable hospitalizations, five diseases were selected as the measurement objects, including hypertension, diabetes, asthma, chronic obstructive pulmonary disease (COPD), as well as congestive heart failure (CHF). We described the avoidable hospitalization rate, average cost and length of stay for avoidable hospitalization cases. Linear probability model and log-linear model were used to control the basic characteristics and disease severity of patients, and to measure the trend of the avoidable hospitalization rate and expenditure of avoidable hospitalizations. RESULTS: From 2015 to 2018, the absolute number of avoidable hospitalizations in the city increased while fluctuating, which reached 125,372 in 2018. Among the five avoidable hospitalizations, the number of hospitalizations for diabetes increased continuously in the 4-year period. Congestive heart failure showed the most significant increase over the four years. Avoidable hospitalizations in the city have remained at a high level, while avoidable hospitalizations of hypertension and asthma fell to levels lower than those in 2015 in 2017 and 2018 after rising in 2016. The cost per hospitalization and length of stay per hospitalization decreased. CONCLUSIONS: Avoidable hospitalizations in the city remain at a high level, and more effective policies should be formulated to guide patients with avoidable hospitalizations, so as to more effectively exploit outpatient services and continuously improve the quality of primary health care services.

Health service underutilization and its associated factors for chronic diseases patients in poverty-stricken areas in China: a multilevel analysis.

BACKGROUND: Underutilization of health services among chronic non-communicable disease sufferers, especially for hypertension (HBP) and diabetes mellitus (DM), was considered as a significant contributing factor to substantial cases in terms of both avoidable morbidity and mortality. However, evidence on health services underutilization and its associated factors in poverty-stricken areas remain scarce based on previous literature. This study aims to describe health services underutilization for people diagnosed with chronic diseases in impoverished regions and to identify its associated factors, which are expected to provide practical implications for the implementations of interventions tailored to the specific needs of disadvantaged residents in rural China to achieve effective utilization of health services in a timely manner. METHODS: Data were collected from a cross-sectional survey conducted through face-to-face interviews among 2413 patients from six counties in rural central China in 2019. The Anderson behavioral model was adopted to explore the associated factors. A two-level logistic model was employed to investigate the association strengths reflected by adjusted odds ratios (AOR) and 95% confidence intervals in forest plots. RESULTS: On average, 17.58% of the respondents with HBP and 14.87% with DM had experienced health services underutilization during 1 month before the survey. Multilevel logistic regression indicated that predisposing factors (age), enabling factors (income and a regular source of care), and need factors (self-reported health score) were the common predictors of health service underutilization both for hypertensive and diabetic patients in impoverished areas, among which obtaining a regular source of care was found to be relatively determinant as a protective factor for health services underutilization after controlling for other covariates. CONCLUSIONS: Our results suggested that the implementation of a series of comprehensive strategies should be addressed throughout policy-making procedures to improve the provision of regular source of care as a significant determinant for reducing health services underutilization, thus ultimately achieving equal utilization of health services in impoverished regions, especially among chronic disease patients. Our findings are expected to provide practical implications for other developing countries confronted with similar challenges resulting from underdeveloped healthcare systems and aging population structures.

Impact of global budget combined with pay-for-performance on the quality of care in county hospitals: a difference-in-differences study design with a propaensity-score-matched control group using data from Guizhou province, China.

BACKGROUND: Provider payment system has a profound impact on health system performance. In 2016, a number of counties in rural Guizhou, China, implemented global budget (GB) for county hospitals with quality control measures. The aim of this study is to measure the impact of GB combined with pay-for-performance on the quality of care of inpatients in county-level hospitals in China. METHODS: Inpatient cases of four diseases, including pneumonia, chronic asthma, acute myocardial infarction and stroke, from 16 county-level hospitals in Guizhou province that implemented GB in 2016 were selected as the intervention group, and similar inpatient cases from 10 county-level hospitals that still implemented fee-for-services were used as the control group. Propensity matching score (PSM) was used for data matching to control for age factors, and difference-in-differences (DID) models were constructed using the matched samples to perform regression analysis on quality of care for the four diseases. RESULTS: After the implementation of GB, rate of sputum culture in patients with pneumonia, rate of aspirin at discharge, rate of discharge with ß-blocker and rate of smoking cessation advice in patients with acute myocardial infarction increased. Rate of oxygenation index assessment in patient with chronic asthma decreased 20.3%. There are no significant changes in other indicators of process quality. CONCLUSIONS: The inclusion of pay-for-performance in the global budget payment system will help to reduce the quality risks associated with the reform of the payment system and improve the quality of care. Future reform should also consider the inclusion of the pay-for-performance mechanism.

10 years of health-care reform in China: progress and gaps in Universal Health Coverage.

In 2009, China launched a major health-care reform and pledged to provide all citizens with equal access to basic health care with reasonable quality and financial risk protection. The government has since quadrupled its funding for health. The reform's first phase (2009-11) emphasised expanding social health insurance coverage for all and strengthening infrastructure. The second phase (2012 onwards) prioritised reforming its health-care delivery system through: (1) systemic reform of public hospitals by removing mark-up for drug sales, adjusting fee schedules, and reforming provider payment and governance structures; and (2) overhaul of its hospital-centric and treatment-based delivery system. In the past 10 years, China has made substantial progress in improving equal access to care and enhancing financial protection, especially for people of a lower socioeconomic status. However, gaps remain in quality of care, control of non-communicable diseases (NCDs), efficiency in delivery, control of health expenditures, and public satisfaction. To meet the needs of China's ageing population that is facing an increased NCD burden, we recommend leveraging strategic purchasing, information technology, and local pilots to build a primary health-care (PHC)-based integrated delivery system by aligning the incentives and governance of hospitals and PHC systems, improving the quality of PHC providers, and educating the public on the value of prevention and health maintenance.

Nurse staffing in large general hospitals in China: an observational study.

BACKGROUND: The appropriate staffing of nurses not only reflects the situation of nursing management of human resource, but also is related to the nursing quality in hospitals. This study investigated the staffing of nurses in large general hospitals in China. METHODS: In this study, a database established by the National Centre for Nursing Care Quality Control, which conducted a national survey of the staffing of nurses in China mainland in 2017, was analysed. The time-point survey data of 20 375 departments in 668 large general hospitals in China were obtained, including the information of nurses and patients during the day (10:00 am) and at night (10:00 pm). Then, the staffing of nurses was evaluated by calculating the nurse to patient ratio (the average number of patients assigned to a nurse, NTP ratio). The Kruskal-Wallis test was performed to compare the NTP ratios during the day and at night among different regions and departments. RESULTS: In large general hospitals, a nurse takes care of eight patients (NTP ratio = 1:8.0) during the day and 23 patients at night (NTP ratio = 1:23) on average. There were significant differences between day and night. In terms of different regions, a nurse in the hospitals in the western region takes care of 7.8 patients during the day (NTP ratio = 1:7.8) on average, and the nursing resource in the western region is more adequate than that in the eastern (1:8.0) and central (1:8.0) regions. At night, the eastern region has a higher level of NTP (1:23.0). In terms of departments, a nurse working in the ICU takes care of two patients during the day (NTP ratio = 1:2.0) and 2.9 patients at night (NTP ratio = 1:2.9). The level of NTP in the oncology department is relatively higher: 9.3 during the day and 34.0 at night. Other departments including internal medicine, surgery, obstetrics and gynaecology, paediatrics, and geriatrics have NTP ratios of 1:7-8 during the day and 1:18-25 at night. CONCLUSIONS: In China, the nurse staffing of large general hospitals has some regional and departmental patterns. The low level of nurse staffing at night may be a problem worthy of attention; the Chinese government needs to establish standards for different periods and departments to improve efficiency and quality of nursing.

Changes in income-related inequalities of depression prevalence in China: a longitudinal, population study.

PURPOSE: This study aimed to measure the income-related inequality of depressive symptoms and its trends among middle-aged and elderly people in China. METHODS: Data were extracted from the 2011 baseline and 2015 follow-up of the China Health and Retirement Longitudinal Study (CHARLS), a nationally representative survey for people aged 45 years and more. Depressive symptoms were evaluated with the Chinese version of the ten-item Center for Epidemiologic Studies Depression Scale. Five relative income levels were derived from ratios between the participants' annual per capita household expenditure, excluding medical expenditure, and the median PCE of their cities. The concentration curve and index were used to compare the magnitude of income-related inequality between 2 years. A logistic regression model was used to control the other socio-economic factors. RESULTS: The prevalence of depression among middle-aged and elderly people in China decreased from 37.0% (5540 of 14,956 participants) in 2011 to 32.7% (5606 of 17,165) in 2015. However, the absolute value of the standardized concentration index increased from 0.005 to 0.028. Although the second lowest-income group had the greatest improvement in the decline of prevalence (5.7%, from 38.6 to 32.9%), the lowest-income group had only the minimal decline (2.4%, from 40.6 to 38.2%). In 2015, there were significant differences between the lowest-income group and other four groups while the differences among other four groups were not statistically significant. CONCLUSIONS: The prevalence of depression among the middle-aged and elderly in China is declining, but the issue of income-related inequality has been exacerbated. The fairness of mental health deserves more attention.

Level and variation on quality of care in China: a cross-sectional study for the acute myocardial infarction patients in tertiary hospitals in Beijing.

BACKGROUND: Quality of care (QoC) attracts global concerns when unsafe and misuse of healthcare wastes resources and endangers people's health, especially in low- and middle-income countries. However, little is known about quality of care delivered in China. This study was intended to gauge the quality of care for acute myocardial infarction (AMI) patients in Beijing and identify the quality gaps across tertiary hospitals. METHODS: One thousand two hundred twenty eight patients, covered by Employee Essential Health Insurance Scheme and diagnosed of AMI, was sampled from 14 large comprehensive hospitals in Beijing, China. Chart review study was conducted through the discharge data and medical records of inpatients to evaluate 6 quality outcomes of interest, including the use of aspirin, beta blocker, and statin at discharge; use of aspirin within 24 h at arrival; angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blocker (ARB) for left ventricular systolic dysfunction (LVSD); percutaneous transluminal coronary intervention (PCI) within 90 min at arrival. RESULTS: Of the 1228 subjects, the mean age was 60.8 (11.8 SD) years and 83.0% were male. The overall medication prescribed was highly compliant with the clinical guidelines (97.0% [95% CI 96.8-97.2] for aspirin and 96.3% [95% CI 96.0-96.5] for statin), except for beta-blocker (83.6% [95% CI 83.0-84.1]) and ACEI/ARB use (61.4% [95% CI 60.7-62.2]). More than half of eligible patients did not receive appropriate PCI therapy (44.0% [95% CI 42.5-45.4]). Great variations across hospitals was observed in aspirin within 24 h and beta-blocker at discharge (P < 0.001), and the risk-adjusted results remained robust. CONCLUSION: Underuse of recommended treatment and significant variations of quality were found for AMI patients across tertiary hospitals in Beijing. It raised great concerns on poorer quality of care in other less-developed areas with less medical resources. Practical actions are needed in reducing quality gaps to ensure the delivery of quality care.

Short-term and long-term unintended impacts of a pilot reform on Beijing's zero markup drug policy: a propensity score-matched study.

BACKGROUND: In September 2012, Beijing, the capital of China, selected five tertiary hospitals as pilots to remove the previously allowed 15% markup for drug sales. However, while most research demonstrated the significant decrease in drug sales, the core issue of high health expenditure was not well solved because of the unintended policy impact. This study aimed to empirically evaluate the short-term and long-term unintended impacts on controlling medical expenses of Beijing's zero markup drug policy from 2012 to 2015. METHODS: This study extracted 2012-2015 individual-level data from the Beijing Urban Employee Basic Medical Insurance (UEBMI) database and performed a propensity score-matched analysis to evaluate the short-term and long-term impacts on controlling medical expenses. All inpatients in the 5 pilot reform hospitals were selected as the intervention group, while inpatients in other tertiary hospitals were selected as the control group. RESULTS: A total of 520,996 inpatients were extracted in this study. For patients in the pilot hospitals, the total expenditures per admission decreased from 17,140.3 yuan in 2012 to 15,430.1 yuan in 2013 and then increased to 16,789.8 yuan in 2015. Expenditure on drugs reduced from 5811.7 yuan in 2012 to 3903.4 yuan in 2015. However, a significant substitution effect of medical consumables was first observed in the third quarter of 2014, which undermined the impact of the policy. In the long-term, the intervention group and control group demonstrated the same trend. CONCLUSIONS: After the zero markup drug policy, expenditure on drugs revealed a continuous decline. However, the decline in total expenditure was weakened by the substitution effect of medical consumables in the long term.

Improving health equity: changes in self-assessed health across income groups in China.

BACKGROUND: Beginning in 2010, China has endeavoured to expand health coverage and provide residents with fair access to primary health care with the intention of improving health equity. This study aims to measure changes in income-related health inequity in China between 2010 and 2014. METHODS: Data were extracted from the nationally representative annual survey of the China Family Panel Studies in 2010 and 2014 with a first wave of 31,743 respondents and a second wave of 32,006 respondents over age 15. In both years, subjects were stratified into the following five categories of income: poorest 20%, lower 20%, medium 20%, higher 20% and richest 20%. The concentration curve and index was used to compare the distribution of health status in income quintiles, and a logistic model was used to examine the relationship between health and socioeconomic indicators with self-assessed health as the primary outcome of interest. RESULTS: Income was significantly associated with self-assessed health in China. The concentration curve was above the line of equality in both years, while the self-assessed health line in 2014 was closer to the equality line. The concentration index (CIN) displayed the similar result of decreasing inequality, with the CIN in 2014 (- 0.157) closer to zero (the line of equality) than that of 2010 (- 0.167). In 2010, there was a decreasing trend of people reporting poor health from the poorest to the richest, while in 2014, there was no significant difference between the poorest and lower 20% or between the higher 20% and the medium 20%. The odds ratio of the prevalence of self-reporting poor health between the poorest and richest increased from 0.555 (95% CI: 0.484-0.636) in 2010 to 0.598 (95% CI: 0.513-0.696) in 2014. CONCLUSIONS: From 2010 to 2014, the self-assessed health gap between income groups in China decreased, and health equity improved. However, health differences remain. In order to achieve better health for all, China should further strengthen the role of primary care in reducing health inequity.

The role of health system governance in strengthening the rural health insurance system in China.

BACKGROUND: Systems of governance play a key role in the operation and performance of health systems. In the past six decades, China has made great advances in strengthening its health system, most notably in establishing a health insurance system that enables residents of rural areas to achieve access to essential services. Although there have been several studies of rural health insurance schemes, these have focused on coverage and service utilization, while much less attention has been given to the role of governance in designing and implementing these schemes. METHODS: Information from publications and policy documents relevant to the development of two rural health insurance policies in China was obtained, analysed, and synthesise. 92 documents on CMS (Cooperative Medical Scheme) or NCMS (New Rural Cooperative Medical Scheme) from four databases searched were included. Data extraction and synthesis of the information were guided by a framework that drew on that developed by the WHO to describe health system governance and leadership. RESULTS: We identified a series of governance practices that were supportive of progress, including the prioritisation by the central government of health system development and certain health policies within overall national development; strong government commitment combined with a hierarchal administrative system; clear policy goals coupled with the ability for local government to adopt policy measures that take account of local conditions; and the accumulation and use of the evidence generated from local practices. However these good practices were not seen in all governance domains. For example, poor collaboration between different government departments was shown to be a considerable challenge that undermined the operation of the insurance schemes. CONCLUSIONS: China's success in achieving scale up of CMS and NCMS has attracted considerable interest in many low and middle income countries (LMICs), especially with regard to the schemes' designs, coverage, and funding mechanisms. However, this study demonstrates that health systems governance may be critical to enable the development and operation of such schemes. Given that many LMICs are expanding health financing system to cover populations in rural areas or the informal sectors, we argue that strengthening specific practices in each governance domain could inform the adaptation of these schemes to other settings.

Introducing diagnosis-related groups: is the information system ready?

Diagnosis-related group (DRG) system is a classification system widely used in health managements, the foundation of which lies in the medical information system. A large effort had been made to improve the quality of discharge data before the introduction of DRGs in Beijing. We extract discharge data from 108 local hospitals spanning 4 years before and after standardization to evaluate the impact of standardization on DRG grouping performance. The data was grouped on an annual basis in accordance with Beijing's local DRG system. Proportion of ungrouped data, coefficient of variation (CV) and reduction in variance (RIV) were used to measure the performance of the DRG system. Both the descriptive and regression analysis indicate a significant reduction in terms of ungrouped data and CV for expenditure, increase of RIV for expenditure and length of stay. However, when there was no intervention, that is, between 2005 and 2006 and between 2008 and 2009, changes in these indicators were all insignificant. Therefore, the standardization of discharge data did improve data quality and consequently enhanced the performance of DRGs. Developing countries with a relatively weak information infrastructure should strengthen their medical information system before the introduction of the DRG system.

[An empirical analysis on the substitution effect of outpatient services on inpatient services].

OBJECTIVE: To study the substitution effect of outpatient services on inpatient services and provide suggestions on designing outpatient policies. METHODS: The data were from 13 districts/counties in one area of eastern China from 2007 to 2013 for the new cooperative medical scheme. This study employed a fixed effects model to analyze the impacts of outpatient visit times, expenditure amounts and reimbursements on inpatient services. RESULTS: One outpatient visit reduced the total amount of inpatient services by 20 Yuan. An increase of 10,000 Yuan outpatient reimbursements saved 9,700 Yuan inpatient expenses. An increase of 10,000 Yuan outpatient expenses led to a decrease of 3,000 Yuan inpatient reimbursements. The outpatient services did not increase the inpatient hospitalization times significantly. In particular, the effects of the outpatient services were mainly on the inpatient services at the district/county levels, and no significant impacts on the outpatient services at the city levels. CONCLUSION: There is a substitution effect of outpatient services on inpatient services. The health insurance departments should take this substitution effect into account and shift more funds on outpatient series, when they design outpatient and inpatient reimbursement policies.

[Influence of contractual medical association on inpatient service performance].

OBJECTIVE: To study the influence of contractual medical association on inpatient service performance. METHODS: The data came from "Database of Inpatient Record" administered by Department of Medical Insurance. Using diagnosis related groups (DRG) as the tool of risk-adjustment, the third-tier general hospitals and second-tier general hospitals in medical alliance as the intervention group, and the average level of the same grade local hospitals as the control group, the influence of medical alliance on inpatient service performance was evaluated. The difference in difference (DID) method was used for the data analysis. The assessing indicators included the number of DRG group, case mix index (CMI), the total weight, cost efficiency index and time efficiency index. RESULTS: After the establishment of medical association, compared with the average level of the same grade local hospitals, in the third-tier general hospitals of medical alliance, the growth rate of the total weight had declined, and cost efficiency index had increased, while in the second-tier general hospitals of medical alliance, the CMI value had declined, and the cost efficiency index had increased. CONCLUSION: Contractual medical association played a role of triage patients, and improved the service levels and management efficiency of the second-tier general hospitals.

[Impact of primary care oriented outpatient benefit package design in new rural cooperative medical system on hypertension outpatient services utilization].

OBJECTIVE: To study the impact of primary care oriented outpatient benefits package design of outpatient services coverage and ladder reimbursement of county, town and village levels in the new rural cooperative medical system (NRCMs) on hypertension outpatient services utilization. METHODS: The panel data of treatment and control groups in 2009 and 2011 before and after the policy reform were drawn from the household survey data of the innovative payment system project. The difference in difference (DID) method was used for data analysis. The outcome indicators included the utilization of outpatient services of patients with self-reported hypertension and their main treatment locations. RESULTS: The primary care oriented outpatient benefit package design in the NRCMs reduced the probability of no treatment in the latest three months of hypertension by 10.2 percent points. Meanwhile, it increased the probability of choosing village clinic as the preferred location by 15.7 percent points. CONCLUSION: Primary care oriented outpatient benefits package design lead patients with hypertension to use the nearest outpatient services at low risk of disease.

The Impact of Centralized Procurement on Treatment Patterns for Myocardial Infarction and More Principled Utilization of Coronary Stents.

Reducing the price of expensive medical products through centralized procurement is generally considered an effective way to save public medical resources. Against this background, this paper presents an analysis of the impact of centralized procurement in China by comparing the treatment costs and patterns for acute myocardial infarction (AMI) patients before and after the introduction of this method of purchasing, with specific reference to the use of coronary stents. We found that, after the implementation of centralized procurement for coronary stents, the total expenditure of AMI cases receiving percutaneous coronary interventions with stent implantation (PCI with stents) dropped by 23.4%. The use rate of PCI with stents decreased by 32.5%, with the most significant decrease being evident in cases in which two stents were used simultaneously (32.9%). Meanwhile, percutaneous coronary interventions with balloon implantation (PCI with balloons) increased by 31.5% and coronary artery bypass grafting (CABG) increased by 80.3%. Based on these patterns, it can be observed that the use of centralized procurement significantly reduced the profits of the relevant medical manufacturers, forcing them to decrease their marketing investments, weakening their influence on providers, and ultimately resulting in a more principled use of coronary stents. We therefore conclude that, with reference to the data cited, the centralized procurement program led not only to a reduction in procurement prices but also to decreased overuse of these expensive medical products.

Patterns of gender inequality perception and depressive symptoms among Chinese adults: The mediating role of marital life satisfaction.

OBJECTIVES: As one of the most severe public health issues, depressive symptoms have attracted wide attention around the world. This study aims to investigate the mediating role of marital life satisfaction in the relationship between gender inequality perception and depressive symptoms. METHODS: Data were obtained from the China Family Panel Studies (CFPS) conducted in 2020. This study incorporated a total of 13,409 married residents aged 20 and above. RESULTS: The residents with middle (B = 0.19, 95 % CI = 0.01, 0.40) or high perception of gender inequality (B = 0.55, 95 % CI = 0.34, 0.75) were more likely to develop depressive symptoms. Marital life satisfaction plays a mediating effect in the relationship between patterns of gender inequality perception and depressive symptoms, and the mediating effect accounted for 4.89 % or 1.37 % of the total impact in the residents with middle or high patterns of gender inequality perception. LIMITATIONS: Further studies need to understand the mechanisms of perceived patterns of gender inequality and depressive symptoms, because the cross-sectional design in this study cannot draw causal inferences. CONCLUSION: Patterns of gender inequality perception are significantly associated with depressive symptoms. Marital life satisfaction plays a mediating role in the relationship between patterns of gender inequality perception and depressive symptoms. It is plausible that nurturing healthy marital relationships could mitigate depressive symptoms in individuals who perceive high degrees of gender disparity.

Relationship between social inequality perception patterns and depressive symptoms among Chinese adults: A national representative longitudinal study.

BACKGROUND: The rising prevalence of depressive symptoms presents a pressing global public health concern, exacerbated by prevailing social inequality. AIM: This study seeks to identify latent profiles of social inequality perception and explore their associations with depressive symptoms. METHODS: Data were obtained from the China Family Panel Studies (CFPS) involving 10,529 residents aged 18 years and above. Latent profile analysis (LPA) was used to identify different patterns of social inequality perception. Multiple linear regression analysis examined the links between these patterns and depressive symptoms. RESULTS: Three distinct patterns of social inequality perception were identified: the disappointed pattern (TDP), the neutral pattern (TNP), and the positive pattern (TPP). Perceived social inequality was significantly associated with short-term and long-term depressive symptoms (ß = .51, 95% CI [0.29, 0.72] vs. ß = .51, 95% CI [0.27, 0.74]). Increases in social inequality perception patterns were also related to more severe depressive symptoms (ß = .55, 95% CI [0.36, 0.74]). CONCLUSIONS: Increasing perceived social inequality is closely linked to elevated depressive symptoms in Chinese adults. This underscores the need for tailored strategies aimed at addressing heightened perceptions of social inequality to reduce the risk of depressive symptoms.
