Updated information concerning trends in suicide rates in elderly in China, 2002-2020.

The aim of this study was to investigate trends in suicide rates (SRs) among the elderly in China. Annual data on SRs among Chinese people ≥ the age of 65 were collected from China's Health Statistics Yearbook from 2002 to 2020. Then, data were stratified by age, region, and sex. Standardized SRs were calculated and analyzed using a conventional joinpoint regression model. Results revealed that overall, SRs among the elderly in China tended to decline from 2002-2020. Fluctuations in SRs, including in 2004-2005 due to the SARS epidemic, in 2009-2010 due to the economic crisis, and in 2019-2020 due to the COVID-19 pandemic, were also observed. Data suggested a relatively greater crude SR among the elderly (vs. young people), in males (vs. females), and in people living in a rural area (vs. those living in an urban area). SRs tended to rise with age. Joinpoint regression analysis identified joinpoints only for males ages 65-69 and over the age of 85 living in a rural area, suggesting that individuals in these groups are more sensitive to negative stimuli and more likely to commit suicide, necessitating closer attention. The findings from this study should help to make policy and devise measures against suicide in the future.

Spatial distribution patterns of human resources allocation in maternal and child healthcare institutions in China from 2016 to 2021

BackgroundIn China, economic, urbanization, and policy differences between the eastern and western regions lead to uneven healthcare resources. This disparity is more pronounced in the west due to fewer healthcare personnel per thousand individuals and imbalanced doctor-to-nurse ratios, which exacerbates healthcare challenges. This study examines the spatial distribution of human resources in maternal and child healthcare from 2016 to 2021, highlighting regional disparities and offering insights for future policy development.MethodsThe data were sourced from the “China Health and Family Planning Statistical Yearbook” (2017) and the “China Health and Health Statistics Yearbook” (2018–2022). This study utilized GeoDa 1.8.6 software to conduct both global and local spatial autocorrelation analyses, using China’s administrative map as the base dataset.ResultsFrom 2016 to 2021, there was an upward trend in the number of health personnel and various types of health technical personnel in Chinese maternal and child healthcare institutions. The spatial distribution of these personnel from 2016 to 2021 revealed clusters characterized as high-high, low-low, high-low and low-high. Specifically, high-high clusters were identified in Guangxi, Hunan, Jiangxi, and Guangdong provinces; low-low in Xinjiang Uygur Autonomous Region and Inner Mongolia Autonomous Region; high-low in Sichuan province; and low-high in Fujian and Anhui provinces.ConclusionsFrom 2016 to 2021, there was evident spatial clustering of health personnel and various health technical personnel in Chinese maternal and child healthcare institutions, indicating regional imbalances.

Association between maternal health service utilization and under-five mortality rate in China and its provinces, 1990–2017

BackgroundThe United Nations (UN) Sustainable Development Goal − 3.2 aims to eliminate all preventable under-five mortality rate (U5MR). In China, government have made efforts to provide maternal health services and reduce U5MR. Hence, we aimed to explore maternal health service utilization in relation to U5MR in China and its provinces in 1990–2017.MethodsWe obtained data from Global Burden of Disease 2017, China Health Statistics Yearbook, China Statistical Yearbook, and Human Development Report China Special Edition. The trend of U5MR in each province of China from 1990 to 2017 was analyzed using Joinpoint Regression model. We measured the inequities in maternal health services using HEAT Plus, a health inequity measurement tool developed by the UN. The generalized estimating equation model was used to explore the association between maternal health service utilization (including prenatal screening, hospital delivery and postpartum visits) and U5MR.ResultsFirst, in China, the U5MR per 1000 live births decreased from 50 in 1990 to 12 in 2017 and the average annual percentage change (AAPC) was − 5.2 (p < 0.05). Secondly, China had a high maternal health service utilization in 2017, with 96.5% for prenatal visits, 99.9% for hospital delivery, and 94% for postnatal visits. Inequity in maternal health services between provinces is declining, with hospital delivery rate showing the greatest decrease (SII, 14.01 to 1.87, 2010 to 2017). Third, an increase in the rate of hospital delivery rate can significantly reduce U5MR (OR 0.991, 95%CI 0.987 to 0.995). Postpartum visits rate with a one-year lag can reduce U5MR (OR 0.993, 95%CI 0.987 to 0.999). However, prenatal screening rate did not have a significant effect on U5MR.ConclusionThe decline in U5MR in China was associated with hospital delivery and postpartum visits. The design and implementation of maternal health services may provide references to other low-income and middle-income countries.

Assessing the price levels of medical service and influential factors: evidence from China

BackgroundMedical service prices play a crucial role in cost containment in China. This study aimed to assess the change in medical service price levels at the macro level and the relationship with relevant macroeconomic factors.MethodsData from the 2022 China Statistics Yearbook, the 2022 China Health Statistics Yearbook, and the 2020 China National Health Accounts Report were used. Time trends of health price levels, utilization, and health expenditure were examined. A time-series regression model was employed to measure the impact of service utilization and medical service prices on total medical service expenditure growth from 2000 to 2021. The Johansen cointegration test was conducted to test the cointegrating relationship between medical service price levels and total medical service expenditure, average wage of employees and CPI. The Granger causality test was performed to observe the direction of causality.ResultsDescriptive analyses showed consistent growth in utilization and medical service price levels from 2000 to 2021. The time-series model indicated that medical service expenditure was influenced by the rise in inpatient admissions and price levels of medical service and medicine. The Johansen cointegration test identified a long-term equilibrium relationship between medical service price levels and total medical service expenditure, average wage and CPI. The change in medical service price levels was the Granger cause of the change in medical service expenditure, but it had no impact on average wage and CPI. However, the change in medical service price levels was influenced by these three macroeconomic factors.ConclusionsThe growth of medical service expenditure in China was driven by inpatient use and price level. There was a long-term equilibrium relationship between medical service price levels and relevant macroeconomic factors. However, medical service price levels only affected medical service expenditure and have no impact on average wage and CPI. It is necessary to improve the value transmission mechanism of medical service prices.

Injury Mortality of Children and Adolescents Aged 0-19 Years - China, 2010-2021.

To examine the recent trends in child injury mortality in China. Injury mortality data of 2010-2021 for children and adolescents aged 0-19 years were from the China Health Statistics Yearbook. Injury mortality disparities across urban vs. rural locations, gender, and age groups were scrutinized. Annual percent change (APC), average annual percent change (AAPC), and their 95% confidence intervals (95% CI) were estiamted usimg Joinpoint regression models. The age-standardized injury mortality significantly dropped from 21.87 to 9.41 per 100,000 population among children and youth aged 0-19 years during 2010-2021, with an AAPC of -6.7% (95% CI: -8.2%, -5.2%). The urban-rural disparity and gender gap in injury mortality reduced gradually. In 2021, drowning and road traffic crashes were the top two causes of child injury deaths, explaing 31.1% and 27.9% of total injury deaths, respectively. Suffocation accounted for 62.3% of injury deaths among infants younger than a year. Alarmingly, the suicide mortality rate rose from 2.16 to 3.42 per 100,000 population between 2010 and 2021 among teenagers aged 15-19 years. Subgroup analyses yielded similar results. During 2010-2021, the injury mortality decreased significantly among Chinese children and adolescents, and the responding urban-rural disparities narrowed.

Human resource allocation status and equity research of Centers for Disease Control and Prevention in China from 2016 to 2020.

In recent years, the development of global public health has become a matter of great concern and importance for governments worldwide. China, as the largest developing country, plays a crucial role in shaping the development of the public health and its ability to respond to sudden public health emergencies through the fairness of its human resource allocation in center for disease control and prevention (CDC). This study aims to analyze the situation of health human resource allocation in the China Centers for Disease Control and Prevention (China CDCs), assess the fairness of the allocation, and provide reference for the rational allocation of human resources. We selected data from the China Health Statistics Yearbook on healthcare technical personnel, other technical personnel, managerial personnel, and workforce technical personnel of China CDCs for the period of 2016-2020. We utilized the Health Resource Density Index to evaluate the level of human resource allocation in China CDCs. Additionally, we used the Gini coefficient and Theil index to assess the fairness of human resource allocation in China CDCs from both a population and geographical perspective. Firstly, the educational qualifications and professional titles of CDC staff have improved, but the workforce is aging. Secondly, HRDI development trends vary among different personnel types and regions with varying levels of economic development. Finally, the results of the Gini coefficient and Theil index indicate that population distribution fairness is better than geographical distribution fairness. Overall, the unfair population distribution is primarily due to regional disparities. The China CDCs should tailor different standards for the allocation of health human resources based on regional characteristics, aiming to enhance the accessibility of health human resources in various regions and achieve equitable allocation.

Trend and Equity in Maternal and Child Health Resource Allocation in China Since the New Health System Reform: A Nationwide Study from 2008 to 2020.

China has made considerable efforts to promote the development of maternal and child health (MCH) care since the new health system reform in 2009. This study aims to evaluate the trend and equity of MCH resources allocation in China from 2008 to 2020 and provide a reference for rational distribution of MCH resources. Data were collected from the China Health Statistics Yearbook and China Statistics Yearbook. The number of MCH hospitals, licensed (assistant) physicians, registered nurses and beds were selected for the measurement of the equity of MCH resources allocation. The Health Resource Agglomeration Degree and Theil index were used in evaluating MCH resource allocation equity and to compare differences among regions. From 2008 to 2020, the average annual growth rates for MCH hospitals, beds, licensed (assistant) physicians, and registered nurses were 0.72%, 6.95%, 5.04%, and 9.57%, respectively. However, regional disparities in the equity of MCH resource allocation have been identified. Although the western region has shown growth in MCH resource allocation by geography, the agglomeration degree of the four indicators remains less than 1, significantly lower than the average value of greater than 2 in the eastern region. Additionally, the equity of human resource allocation in the western region is lower than the equity in the allocation of institutions. In the densely populated eastern region, the equity of MCH resource allocation by population is decreasing, with the agglomeration degree of all four indicators below 1 in 2020. The disparity in healthcare resource allocation within regions is the main cause of inequitable MCH resource allocation in China. The allocation of MCH resources in China has improved since 2009, however, geographic equity needs further improvement, particularly in densely populated regions. Population and geographic balances should be considered in the development and implementation of MCH resource allocation policies, and improving intraregional equity should be the focus.

Dynamic distribution, regional differences and convergence of health workforce allocation in township health centers in China

This study evaluated the dynamic distribution, regional differences, and convergence of health workforce allocation in Township Health Centers in China during 2011–2020 using data obtained from the China Health Statistics Yearbook (2012–2021). The Gini coefficient and kernel density estimation were chosen to examine the dynamic distribution and regional differences in health workforce allocation in Township Health Centers in China and their components. σ convergence and β convergence were used to investigate the change trend of health workforce allocation in Township Health Centers. The results show that between 2011 and 2020, the number of licensed doctors and registered nurses per thousand population in Township Health Centers both increased largely and regional disparities still exist. In 2020, the largest differences in the density of licensed doctors and registered nurses were found in the eastern and central regions, respectively, and the intensity of trans-variation contributed the most to the overall disparities. The allocation of licensed doctors and registered nurses both exhibited σ convergence, absolute and conditional β convergence, indicating that the regional differences in health workforce in THCs among provinces will decrease. The growth of healthcare workforce was positively impacted by the urbanization rate, growth rate of government health expenditures and growth domestic product per capita, but negatively impacted by population density in rural areas and fiscal self-sufficiency.

A comparative evaluation of child health care in China using multicriteria decision analysis methods

Child health is an important public health issue in China and the Chinese government always attached great importance to child health care. With the implementation of a series of medical and health reforms in China in recent decades, the status of child health improved year by year. Objectives This study aims to comprehensively evaluate if the measures implemented in the medical and health reforms effectively promoted the development of Chinese child health care in recent years and provide theoretical support for future decision-making on the policies of child health care in China. Methods A total of six indicators were selected from the China Health Statistics Yearbook. Based on the multi-criteria decision analysis (MCDA) algorithm, three different evaluation methods were applied in the study, which are the weighted technique for order preference by similarity to an ideal solution (TOPSIS) method, the weighted rank-sum ratio (RSR) method, and the fuzzy comprehensive evaluation (FCE). Each indicator's weight was calculated by the entropy weight methods objectively. The sensitivity analysis was conducted to validate the stability and accuracy of the rank results.Results The results indicated that the rank values of each year’s child health care calculated by the different evaluation methods were not exactly the same, but the overall trend is consistent which is that child health care in China improved year by year from 2000 to 2020. The top 5 were ranked from 2016-2020 and the bottom 5 were ranked from 2000-2004. Conclusions The results indicated that the policies and measures implemented in the medical and health reforms, as well as improved sanitation conditions, availability of healthy food and water, etc., have jointly promoted the development of child health care in China in the past 20 years, providing a scientific theoretical basis for future policy-making to promote child health care.

Research of Combined ES-BP Model in Predicting Syphilis Incidence 1982-2020 in Mainland China.

Syphilis remains a major public health concern in China. We aimed to construct an optimum model to forecast syphilis epidemic trends and provide effective precautionary measures for prevention and control. Data on the incidence of syphilis between 1982 and 2020 were obtained from the China Health Statistics Yearbook. An exponential smoothing model (ES model) and a BP neural network model were constructed, and on this basis, the ES-BP combination model was created. The prediction performance was assessed to compare the MAE (Mean Absolute Error), MSE (Mean Squared Error), MAPE (Mean Absolute Percentage Error), and RMSE (Root Mean Square Error). The optimum ES model was Brown's linear trend model, which had the lowest MAE and MAPE values, and its residual was a white noise sequence (P=0.359). The optimum BP neural network model had three layers with the number of nodes in the input, hidden, and output layers set to 5, 11, and 1, and the mean values of MAE, MSE, and RMSE by five-fold cross-validation were 1.519, 6.894, and 1.969, respectively. The ES-BP combination model had three layers, with model nodes 1, 4, and 1. The lowest mean values of MAE, MSE, and RMSE obtained by five-fold cross-validation were 1.265, 5.739, and 2.105, respectively. The ES, BP neural network, and ES-BP combination models can be used to predict syphilis incidence, but the prediction performance of the ES-BP combination model is better than that of a basic ES model and a basic BP neural network model.

Spatio-temporal pattern, matching level and prediction of ageing and medical resources in China

ObjectivePopulation ageing, as a hot issue in global development, increases the burden of medical resources in society. This study aims to assess the current spatiotemporal evolution and interaction between population ageing and medical resources in mainland China; evaluate the matching level of medical resources to population ageing; and forecast future trends of ageing, medical resources, and the indicator of ageing-resources (IAR).MethodsData on ageing (EPR) and medical resources (NHI, NBHI, and NHTP) were obtained from China Health Statistics Yearbook and China Statistical Yearbook (2011–2020). We employed spatial autocorrelation to examine the spatial–temporal distribution trends and analyzed the spatio-temporal interaction using a Bayesian spatio-temporal effect model. The IAR, an improved evaluation indicator, was used to measure the matching level of medical resources to population ageing with kernel density analysis for visualization. Finally, an ETS-DNN model was used to forecast the trends in population ageing, medical resources, and their matching level over the next decade.ResultsThe study found that China's ageing population and medical resources are growing annually, yet distribution is uneven across districts. There is a spatio-temporal interaction effect between ageing and medical resources, with higher levels of both in Eastern China and lower levels in Western China. The IAR is relatively high in Northwest, North China, and the Yangtze River Delta, but showed a declining trend in North China and the Yangtze River Delta. The hybrid model (ETS-DNN) gained an R2 of 0.9719, and the predicted median IAR for 2030 (0.99) across 31 regions was higher than the median IAR for 2020 (0.93).ConclusionThis study analyzes the relationship between population ageing and medical resources, revealing a spatio-temporal interaction between them. The IAR evaluation indicator highlights the need to address ageing population challenges and cultivate a competent health workforce. The ETS-DNN forecasts indicate higher concentrations of both medical resources and ageing populations in eastern China, emphasizing the need for region-specific ageing security systems and health service industries. The findings provide valuable policy insights for addressing a hyper-aged society in the future.

Disparities of obesity and non-communicable disease burden between the Tibetan Plateau and developed megacities in China.

Non-communicable diseases (NCDs) including risk factors, e.g., obesity, are the major causes of preventable deaths in China, yet NCD disparities in China remain under-studied. This study aimed to compare the determinants and burden of NCDs within four selected provinces in mainland China: the least developed Qinghai-Tibet Plateau group (PG, Tibetan Autonomous Region [TAR] and Qinghai Province) and most developed megacity group (MCG, Shanghai, and Beijing). Studies, reports, and other official sources with comparable data for NCD burden and related determinants for the four provinces were searched. Geographic, demographic, socioeconomic, and dietary characteristics and selected health indicators (e.g., life expectancy) were extracted from the China Statistical Yearbook and China Health Statistics Yearbook. Data on NCD burdens were extracted from the National Chronic Disease and Risk Factor Surveillance Study and other nationally representative studies. The overall NCD mortality rates and prevalence of metabolic risk factors including obesity, hypertension, and diabetes in mainland China have increased in the past 20 years, and this trend is expected to continue. The PG had the highest level of standardized mortality rates (SMRs) on NCDs (711.6-896.1/100,000, 6th/6-level); the MCG had the lowest (290.6-389.6/100,000, 1st/6-level) in mainland China. The gaps in SMRs were particularly high with regard to chronic respiratory diseases (PG 6th/6-level, MCG 1st/6-level) and cardiovascular diseases (6th/6 and 4th/6 in TAR and Qinghai; 1st/6-level and 2nd/6-level in Shanghai and Beijing). In contrast, the prevalence rates of obesity, hypertension, and diabetes were generally higher or comparable in MCG compared to PG. Diabetes prevalence was particularly high in MCG (5th/5-level, 13.36-14.35%) and low in PG (1st/5-level, 6.20-10.39%). However, awareness, treatment, and control of hypertension were poor in PG. Additionally, PG had much lower and severely inadequate intakes of vegetables, fruits, and dairy products, with additional indicators of lower socioeconomic status (education, income, etc.,) compared with MCG. Evidence showed large disparities in NCD burden in China's provinces. Socioeconomic disparity and dietary determinants are probably the reasons. Integrated policies and actions are needed.

How Does Fiscal Decentralization Affect Health Outcomes? Evidence from China.

The impact of fiscal decentralization on health outcomes still has not reached a consensus, and studies conducted in the context of the new round of fiscal and taxation system reform are even less available. China's fiscal decentralization system has its own special characteristics, so it is necessary to analyze the impact of fiscal decentralization on health outcomes before and after the new round of fiscal and taxation system reform in China. Panel data from 2007 to 2019 were obtained through China's Health Statistics Yearbook and China's Statistical Yearbook. The effects of fiscal decentralization on health outcomes before and after the reform are explored separately by SYS-GMM, which introduce a dynamical model with a lag period of the explained variables. The Hansen test is used to determine excessive identification. The AR(2) is used to determine whether the residual term of the differential equation has a second-order serial correlation. Fiscal decentralization consistently had a negative impact on health outcomes, yet government health expenditures did not mediate the impact of fiscal decentralization on health outcomes. Fiscal decentralization had a positive effect on per capita government health expenditure before the new reforms, yet had a negative effect on the percentage of government health expenditures, both before and after the new reform. China's fiscal decentralization has caused local governments to pay insufficient attention to the construction of people's livelihoods, and the problem of insufficient government investment in health has not been improved. The new round of fiscal and taxation system reform has not reversed this situation either. It is recommended to adjust the incentive system for local officials, include medical and health in the evaluation indicators of local governments, optimize the structure of government expenditure, and improve the efficiency of the use of government health expenditure.

Mortality rate of mental disorder trends in China from 2002 to 2020.

The number of people with mental disorders is increasing in China, but there are few studies on the temporal trends and population distribution of mental disorder mortality. The mortality of mental disorders were derived from the China Health Statistics Yearbook published by the National Health and Family Planning Commission. Temporal trends in mortality were examined with a joinpoint regression using annual percent change (APC) and average annual percent change (AAPC). A Poisson regression model was utilized to test the population-level risk factors associated with the death of people with mental disorders. The mortality of mental disorders in rural Chinese residents showed a decreasing trend from 2002 to 2020 [AAPC -2.06%, 95% confidence interval (CI) -3.16 to -0.91%]. The mortality of mental disorders in urban Chinese residents declined between 2005 and 2011 (APC -13.01%, 95% CI -21.08 to -4.13%). The mortality rate of mental disorders has decreased for urban males with an APC of -2.71% (95% CI -4.52 to -0.71) from 2002 to 2020. Urban women showed an increase in mental disorder mortality from 2002 to 2005 and from 2012 to 2020 with APCs of 19.65% (95% CI 0.64-42.32%) and 6.16% (95% CI 2.22-10.33%), respectively. Age was a significant risk factor for mental disorder mortality (odds ratio 1.28, 95% CI 1.23-1.32). The dissemination of medical and health information, investment in medical and health resources, and the modification and optimization of regulations have led to a decrease in mental disorder mortality in China. It is vital to devote greater attention to elderly individuals suffering from mental disorders.

Analyses on the quantity, structure and allocation equity of stomatologists in China

Objective: To study the quantity, structure and allocation equity of stomatologists, in order to provide bases and advices for improving the allocation of stomatologists in China. Methods: On the basis of data from China Health Statistics Yearbooks and Brief Book of Administrative Divisions of the People's Republic of China, the general situation of stomatologists was analyzed by descriptive analysis. Gini coefficient was used to evaluate the allocation equity in 2010 and 2020. Results: The total number of stomatologists reached 2 780 hundred in 2020, which increased by 150.5% compared with that in 2010. The overall quality structure of stomatologists had improved. The gender proportion was balanced and the age distribution was reasonable. The team was mainly composed by the young people, in which the numbers under 44 years old accounted for 71.6% (1 991 hundred/2 780 hundred). The proportion of personnel with senior professional titles decreased to 7.9% (220 hundred/2 780 hundred) while the total number increased to 220 thousand. The distribution of stomatologists by population was fair. Gini coefficients of the whole country as well as the eastern, central and western regions were less than 0.3. Conclusions: The quantity, quality and allocation equity of stomatologists were still insufficient in China. It is necessary to optimize the human resources allocation for stomatologists. It is suggested to increase the talents supply through supply-side reform, medicine-education collaboration and multi-agent participation. And it is suggested to optimize criterions to improve the quality of stomatologists.

Analysis of Rheumatic Heart Disease Mortality in the Chinese Population: A JoinPoint and Age-Period-Cohort Study.

(1) Background: We aimed to analyze rheumatic heart disease (RHD) mortality trends in China’s urban and rural areas and to determine the roles of age, period, and cohort effects. (2) Methods: Based on mortality data extracted from the China Health Statistics Yearbook, we calculated the crude mortality rate of RHD. Age–adjusted rates were computed by the direct method using the 2020 census as the standard population. The annual percentage change (APC) and average annual percentage change (AAPC) were determined by the JoinPoint regression model. The age–period–cohort model was used to estimate the effects of age, period, and cohort. (3) Results: From 2006 to 2020, the general trend in RHD standardized mortality declined. The RHD mortality rate was higher in rural than in urban areas and among females than males. The elderly (over 60 years old) were at high risk for RHD deaths in China. The age effect increased with age, and the cohort effect showed a declining trend as chronology grew, but the period effect was not significant. (4) Conclusions: China has achieved great success in RHD, but RHD mortality may increase with age. Compared with the period effect, age and cohort effects dominated the risk of RHD deaths.

Resource Allocation Equity in the China's Rural Three-Tier Healthcare System.

The rural three-tier healthcare system is an essential part of the Chinese healthcare service system. To ensure rural residents’ equal access to such healthcare services, it is necessary to examine the current status of the healthcare system in rural China and formulate corresponding improvement suggestions. This study therefore collects the data from the China Health Statistics Yearbook, the China Health Yearbook and the China Statistical Yearbook between the years 2004 and 2021 to calculate the Gini coefficient (G), health resource density index (HRDI) and Theil index (T) first, and then perform the Mann–Kendall test afterwards to evaluate the equity of healthcare resource allocation comprehensively. This series of analysis helps in drawing the following conclusions: (1) county and county-level city medical and health institutions (CMHIs) show a higher development trend in comparison with township hospitals (THs) and village clinics (VCs); (2) VCs have higher institutional fairness, while for beds and personnel, CMHIs and THs are more fairly positioned; (3) more specifically for CMHIs and THs, personnel allocation is more fair than beds and institution allocations; (4) the density of healthcare resources in the eastern and central regions is higher than that in the western part, while the intra-regional distribution of beds and personnel in the west and central regions is better than that in the eastern region; (5) intra-regional differences are more significant than inter-regional differences and the fairness according to population distribution is higher than that of geographical area allocation. The results of this study provide theoretical basis for further optimizing the allocation of healthcare resources and improving the fairness of healthcare resources allocation from a macro perspective.

The Service Capability of Primary Health Institutions under the Hierarchical Medical System.

Background: Primary health institutions (PHIs) are the foundation of the whole health system and the basic link to achieve the goal of all people enjoying primary health care. However, the service capability of primary health institutions is not under the hierarchical medical system. Method: Data were collected from the China Health Statistics Yearbook between 2014 and 2020. PHIs included community health centres, community health stations, and township hospitals in our study. The service capability of primary health institutions was analysed from the perspective of structure, process, and results. Structure capability was evaluated using the number of beds, number of personnel, number of health technicians, and proportion of the number of personnel in PHIs accounting for the total number of health personnel. Process capability was evaluated using the number of general practitioners. The number of outpatients and inpatients, medical income, the proportion of drug income, and the average number of patients and beds served by physicians in PHIs per day were employed to evaluate the resulting capability. Results: From 2014 to 2020, the number of community health service centres/stations increased, while the number of township health centres decreased. In the aspect of structure capability, the total number of personnel and health technicians in community health centres/stations and township hospitals both increased during 2014 and 2020. However, the increasing rate in PHIs was a little bit less than that of general medical institutions. The proportion of male health technicians in community health centres and township hospitals both decreased, while the proportion of female technicians in both increased. From 2014 to 2020, the number of beds in PHIs also increased from 138.12 × 104 to 164.94 × 104. However, the proportion of beds in PHIs accounting for the total number of beds in medical institutions decreased. For the resulting capability, from 2014 to 2019, the proportion of diagnosis and treatment times in PHIs decreased from 57.41% to 51.96%, although it increased in 2020. The proportion of inpatients in PHIs decreased from 20.03% to 16.11%. From 2014 to 2020, the utilisation rate of hospital beds in PHIs decreased (from 55.6% to 34% for community health centres and 60.5% to 53.6% for township hospitals). The average daily bed days of doctors in township hospitals was higher than that of doctors in community health service centres. However, the average medical cost of outpatients and the per capita medical cost of inpatients in community health service centres were higher than in township hospitals. Conclusion: In recent years, although the service capability showed an increasing trend in PHIs, the growth rate was lower than the general health institutions. The utilisation rates of PHIs, including beds and physicians, were decreased. Among PHIs, the utilisation in township hospitals was higher than in community health centres with a relatively low price. Under the hierarchical medical system and normalisation period of the COVID-19 epidemic, it is important to improve the service capability to achieve its goal of increasing PHI utilisation and decreasing secondary and tertiary hospital utilisation.

The evolution and inter-sectoral interaction mechanism of China's national medical alliance: An analysis based on complex systems theory.

This work investigates the performance and inter-sectoral interaction mechanism of China's largest vertically integrated care network, the national medical alliance (NMA). The data collected derive from the China Health Statistics Bulletin and the China Health Statistical Yearbook for the period 2009-2018. The data include 64 observation indicators for five medical sectors in the NMA, namely, tertiary hospitals (THS), secondary hospitals (SHS), community health centres (CHCS), township hospitals (TsHS) and professional public health institutions (PPHIS). This research combines complex systems theory with a multilevel structural dynamic factor model, and yields two main results. First, although the trend for the NMA's global factor is increasing, the evolutionary paths for sectoral factors differ substantially. Among the sectoral factors, the sectoral factor of THS continued to decline, and neither the sectoral factor of CHCS nor the sectoral factor of TsHS has significantly improved. Then, the interaction mechanism between the various NMA sectors is investigated. While a close relationship has been formed between THS and CHCS and between SHS and CHCS, there remains no close two-way relationship between either THS and TsHS or THS and SHS. Thus, going forward, to reach the policy expectations, China's NMA implementation must consider the interaction between different constituent sectors.
