RESUMEN

OBJECTIVES: This study aimed to quantify increases in the medical expenditures of public hospitals associated with changes in service use and prices, which could inform policy efforts to curb the future growth of hospital medical expenditures. DESIGN: Nationwide and provincial data regarding service volume, service price and intensity of public hospitals' outpatient and inpatient care from 2008 to 2018 were extracted from the China Health Statistical Yearbooks, and population size data were obtained from the 2019 China Statistical Yearbook. METHODS: A decomposition analysis was performed to measure the relative effects of changes in service use (volume or its subcomponent factors) and service price and intensity on the increase in the inpatient and outpatient total medical expenditures of public hospitals from 2008 to 2018. RESULTS: After adjusting for price inflation, the total medical expenditure of public hospitals increased by approximately threefold from 2008 to 2018. During this period, the increase in service volume was associated with 67.4% of the observed increase in the total medical expenditures in the inpatient sector and 57.2% of the observed increase in the total medical expenditures in the outpatient sector. Most of the service volume effect is due to an increase in the hospital utilisation rate. The growth in the utilisation rate was associated with 73.7% of the observed growth in the total medical expenditures in the inpatient sector and 60.3% of the observed growth in the total medical expenditures in the outpatient sector. CONCLUSION: Service use, rather than price, appears to be the major driver of increases in medical expenditures in Chinese hospitals. An important policy implication for China and other countries with similar drivers is that the effect of controlling price and intensity growth on containing medical costs could be limited and controlling service utilisation growth could be essential.

RESUMEN

BACKGROUND: Fragmentation in China's social health insurance schemes and income gap have been recognised as important factors for the inequitable use of healthcare. This study assessed trends in disparities in healthcare utilisation between and within health insurances in China between 2008 and 2018. METHODS: We used data from the 2008, 2013, and 2018 China National Health Services Survey. Outpatient visit, inpatient admission and foregone inpatient care were chosen to measure healthcare utilisation and underutilisation by health insurances. Absolute differences and rate ratios were generated to examine disparities between and within health insurances, and changes in disparities were analysed descriptively. Pearson χ2 tests were used to test for statistical significance of differences. RESULTS: The outpatient visit rate for respondents covered by the urban resident-based basic medical insurance scheme (URBMI) more than doubled between 2008 and 2018, increasing from 10.5% (9.7-11.2) to 23.5% (23.1-23.8). Inpatient admission rates for respondents covered by URBMI and the new rural cooperative medical scheme (NRCMS) more than doubled between 2008 and 2018, increasing by 7.2 (p < 0.0001) and 7.4 (p < 0.0001) percentage points, respectively. Gaps in outpatient visits and inpatient admissions narrowed across the urban employee-based basic medical insurance scheme (UEBMI), URBMI, and NRCMS through 2008 to 2018, and by 2018 the gaps were small. The rate ratios of foregone inpatient care between NRCMS and UEBMI fell from 0.9 (p > 0.1) in 2008 to 0.8 (p < 0.0001) in 2018. Faster increases in outpatient and inpatient utilisation and greater reductions in foregone inpatient care were observed in poor groups than in wealthy groups within URBMI and NRCMS. However, the poor groups within UEBMI, URBMI, and NRCMS were always more likely to forego inpatient care in comparison with their wealthy counterparts. CONCLUSIONS: Remarkable increases in healthcare utilisation of URBMI and NRCMS, especially among the poorest groups, were accompanied by improvements in inequality in healthcare utilisation across UEBMI, URBMI, and NRCMS, and in income-based inequality in healthcare utilisation within URBMI and NRCMS. However, the poor groups were always more likely to forego admission to hospital, as recommended by doctors. We suggest further focus on the foregoing admission care of the poor groups.

RESUMEN

BACKGROUND: Patient trust in physicians, which can be considered a collective good, is necessary for an effective health care system. However, there is a widespread concern that patient trust in physicians is declining under various threats to the physician-patient relationship worldwide. This article aimed to assess patient trust in physicians through a quantitative study in Shanghai, China, and to provide appropriate suggestions for improving the trust in China. METHODS: The data from a survey conducted in Zhongshan Hospital and Shanghai Tenth People's Hospital, which are two tertiary public hospitals in Shanghai, were used in this study. Patient trust in physicians was the dependent variable. Furthermore, a 10-item scale was used to precisely describe the dependent variable. The demographic characteristics were independent variables of trust in physicians. Binomial logistic regression was employed to analyze the factors associated with the dependent variable, which was divided into two categories on the basis of the responses (1: Strongly agree or agree and 0: Strongly disagree, disagree, or neutral). RESULTS: This study found that 67% of patients trusted or strongly trusted physicians. The mean score of patient trust in physicians was 35.4 from a total score of 50. Furthermore, patient trust in physicians was significantly correlated with the age, education level, annual income, and health insurance coverage of the patients. CONCLUSIONS: Patient trust in physicians in Shanghai, China is higher than previously reported. Furthermore, the most crucial reason for patient distrust in physicians is the information asymmetry between patients and physicians, which is a natural property of the physician-patient relationship, rather than the so-called for-profit characteristic of physicians or patients' excessive expectations.

RESUMEN

OBJECTIVE: There is a lack of data focusing on non-communicable disease (NCD) mortality in the Chinese elderly population over the past decade. METHODS: Using mortality data from the Chinese Health Statistics, we explored the crude and age-standardized mortality trend of three major NCDs in the Chinese population ≥65 years of age from 2002 to 2010, namely, malignant neoplasms, heart diseases, and cerebrovascular diseases. Subpopulations characterized as rural and urban residence, and by gender and age were examined separately. RESULTS: Mortality increased with age and was higher among males than among females across the three NCDs, with the gender difference being most remarkable for malignant neoplasms and least for heart diseases mortality. Condition-specific crude mortalities increased between 2002 and 2010, overall and in all the pre-specified subpopulations. After age-standardization, rising trends were observed for people ≥65 years old, and condition-specific mortalities generally increased in rural regions and decreased in urban regions, especially for cerebrovascular diseases. CONCLUSIONS: There were increasing trends for mortality due to malignant neoplasms, heart diseases, and cerebrovascular diseases in China between 2002 and 2010, which were largely driven by the population aging. Disparities existed by rural and urban residence, gender, and age.

RESUMEN

BACKGROUND: Previous studies suggest that mortality from congenital heart diseases (CHDs) is declining in the United States. But we do not know what the CHD mortality trend is in China, especially the rural versus urban patterns. Our study aimed to determine recent changes in death caused by CHD in China and describe CHD mortality in rural and urban Chinese populations. METHODS: The data source was the China Ministry of Health 2003 to 2010 annual reports. Mortality was defined as death caused by CHD. Mortality rates for each year were calculated per 10,000,000 person-years. Poisson regression and descriptive analyses were conducted for overall trend and subgroup analysis was conducted by sex, age, and urban versus rural residency to understand potential disparities in mortality. RESULTS: From 2003 to 2010, the overall mortality rate increased from 141 per 10,000,000 person-years in 2003 to 229 per 10,000,000 person-years in 2010, a 62.4% relative increase. This represents a region-sex adjusted annual increase of 9% (incidence rate ratio, 1.09; 95% confidence interval, 1.09-1.10). The increase in CHD mortality was not uniformly observed across age groups, urban versus rural residence, and sex. The relative increases were 65.3%, 212.2%, and 131.7% for ages 1 to 10 years, 21 to 64 years, and 65 years or older groups, respectively. Urban areas had a relative increase of 154.5% versus 5.3% for rural areas. Females who lived in an urban environment had a relative increase of 313.5%. CONCLUSIONS: Our observation showed an obvious increasing trend of CHD mortality in China. What is more, the increase in CHD mortality was not uniformly observed across subgroups. Such information is needed for strategy-making procedures.

RESUMEN

Over the past 2 decades, significant progress has been made in improving the health-care system and people's health conditions in China. Following rapid economic growth and social development, China's health-care system is facing new challenges, such as increased health-care demands and expenditure, inefficient use of health-care resources, unsatisfying implementation of disease management guidelines, and inadequate health-care insurance. Facing these challenges, the Chinese government carried out a national health-care reform in 2009. A series of policies were developed and implemented to improve the health-care insurance system, the medical care system, the public health service system, the pharmaceutical supply system, and the health-care institution management system in China. Although these measures have shown promising results, further efforts are needed to achieve the ultimate goal of providing affordable and high-quality care for both urban and rural residents in China. This article not only covers the improvement, challenges, and reform of health care in general in China, but also highlights the status of respiratory medicine-related issues.

RESUMEN

BACKGROUND: The work of developing clinical practice guidelines began just a little more than ten years ago in China. Up to now, there have been few studies about them. OBJECTIVES: To review and analyze the status of Chinese clinical practice guidelines in 1997-2007. METHODS: All Chinese guidelines from 1997-2007 were collected, and made a regression analysis, and a citation analysis for evaluating the impact of guidelines. To analyze the developing quality, the most influential guidelines were evaluated with AGREE instrument, and each guideline was evaluated to check for any updating. In order to analyze the objective and target population, all guidelines were classified and counted separately according to disease/symptom center, and whether towards specialists or general practitioners. RESULTS: 143 guidelines were collected. An exponential function equation was established for the trend in the number of guidelines. The immediacy index in every year was very low while the average citation rate was not. Both the percentages of highly cited and never cited were high. For the evaluation with AGREE, only the average score of clarity and presentation was high (89.9%); the remaining were much lower. Editorial independence scored 0. Only 27 (18.9%) of 143 guidelines, were found to be evidence-based. Only a few had ever been updated, with an average updating interval of 5.2 years. Only 2.1% were symptom-centered, and only 4.2% were aimed at general practitioners. CONCLUSION: Much progress has been obtained for Chinese guidelines development. However, there were still defects, and greater efforts should be made in the future.

RESUMEN

This article aims at building clinical data groups for Electronic Medical Records (EMR) in China. These data groups can be reused as basic information units in building the medical sheets of Electronic Medical Record Systems (EMRS) and serve as part of its implementation guideline. The results were based on medical sheets, the forms that are used in hospitals, which were collected from hospitals. To categorize the information in these sheets into data groups, we adopted the Health Level 7 Clinical Document Architecture Release 2 Model (HL7 CDA R2 Model). The regulations and legal documents concerning health informatics and related standards in China were implemented. A set of 75 data groups with 452 data elements was created. These data elements were atomic items that comprised the data groups. Medical sheet items contained clinical records information and could be described by standard data elements that exist in current health document protocols. These data groups match different units of the CDA model. Twelve data groups with 87 standardized data elements described EMR headers, and 63 data groups with 405 standardized data elements constituted the body. The later 63 data groups in fact formed the sections of the model. The data groups had two levels. Those at the first level contained both the second level data groups and the standardized data elements. The data groups were basically reusable information units that served as guidelines for building EMRS and that were used to rebuild a medical sheet and serve as templates for the clinical records. As a pilot study of health information standards in China, the development of EMR data groups combined international standards with Chinese national regulations and standards, and this was the most critical part of the research. The original medical sheets from hospitals contain first hand medical information, and some of their items reveal the data types characteristic of the Chinese socialist national health system. It is possible and critical to localize and stabilize the adopted international health standards through abstracting and categorizing those items for future sharing and for the implementation of EMRS in China.

RESUMEN

BACKGROUND: National Breast and Cervical Cancer Early Detection Program (NBCCEDP) has provided free or low-cost mammograms to low-income or no health insurance women in all of the states of the United States (US) since 1997. The objective of this study was to understand whether health insurance and annual household income impacted the mammography utilization since the implementation of NBCCEDP, in order to evaluate how the implementation of NBCCEDP impacted mammography utilization among American women. METHODS: Data were from the database of Behavioral Risk Factor Surveillance System (BRFSS) of the CDC in US. Mammography utilization was measured by whether the American woman aged 40 to 64 years had the mammography within the last two years. The chi square test and multivariate Logistic regression were used to evaluate the associations between mammography utilization and health insurance, annual household income, and other factors for any given year. RESULTS: From 2000 to 2008, the rate of mammography utilization among participants had a steady decrease on the whole from 86.7% to 83.8%. The results showed that the mammography utilization correlated significantly with health insurance and annual household income for any given year. The results also showed that compared with participants who were uninsured, those who were insured had a greater times higher rate of mammography in 2008 than any other year from 2000 to 2008, and compared with participants whose annual household income was below $15 000, those whose annual household income was above $50 000 had a greater times higher rate of mammography in 2008 than in 2004 and 2006. CONCLUSIONS: Health insurance and annual household income impacted the mammography utilization for any given year from 2000 to 2008, and the implementation of NBCCEDP has not achieved its original goal on breast cancer screening.

RESUMEN

BACKGROUND: According to the regulations of the Chinese and Shanghai governments, migrant workers employed in Shanghai should all be entitled to Shanghai Migrant Worker Hospitalization Insurance (SMWHI) without premium and the vast majority should also have the New Rural Cooperative Medical System (NRCMS). This study aimed to examine the status of the coverage and utilization of health insurance among migrant workers employed in Shanghai. METHODS: Quantitative and qualitative research methods were employed in the study. A survey of 1020 migrant workers employed in Shanghai was conducted in 2010 with a structured questionnaire. Focus group discussions were held with respondents who were unable to maintain health insurance coverage through NRCMS or SMWHI. In-depth interviews were held with village heads and employers of the migrant workers, migrant workers who were hospitalized within the last year, and various individuals employed by the insurance agencies. RESULTS: The study found that 72.9% and 36.5% of migrant workers were covered by NRCMS or SMWHI, respectively, while 16.7% of them had no health insurance. The coverage by NRCMS among migrant workers correlated significantly with education level and workplace, while the coverage by SMWHI correlated significantly with the length of employment in Shanghai and workplace. The qualitative results confirmed that migrant workers were the main group who were not covered by NRCMS, and the coverage by SMWHI was completely dependent upon the employers of the migrant worker. The results also showed that health insurance utilization among migrant workers was strongly limited by hospital location. CONCLUSIONS: We observed that the status of health insurance among migrant workers was not accordant with theory, and that Chinese health insurance policy should be further reformed in order to realize full coverage and equal utilization of health insurance among migrant workers in China.

RESUMEN

BACKGROUND: As an important outcome of the health system, equity in health service utilization has attracted an increasing amount of attention in the literature on health reform in China in recent years. The poor, who frequently require more services, are often the least able to pay, while the wealthy utilize disproportionately more services although they have less need. Whereas equity in health service utilization between richer and poorer populations has been studied in urban areas, the equity in health service utilization in rural areas has received little attention. With improving levels of economic development, the introduction of health insurance and increasing costs of health services, health service utilization patterns have changed dramatically in rural areas in recent years. However, previous studies have shown neither the extent of utilization inequity, nor which factors are associated with utilization inequity in rural China. METHODS: This paper uses previously unavailable country-wide data and focuses on income-related inequity of inpatient utilization and its determinants in Chinese rural areas. The data for this study come from the Chinese National Health Services Surveys (NHSS) conducted in 2003 and 2008. To measure the level of inequity in inpatient utilization over time, the concentration index, decomposition of the concentration index, and decomposition of change in the concentration index are employed. RESULTS: This study finds that even with the same need for inpatient services, richer individuals utilize more inpatient services than poorer individuals. Income is the principal determinant of this pro-rich inpatient utilization inequity- wealthier individuals are able to pay for more services and therefore use more services regardless of need. However, rising income and increased health insurance coverage have reduced the inequity in inpatient utilization in spite of increasing inpatient prices. CONCLUSIONS: There remains a strong pro-rich inequity of inpatient utilization in rural China. However, a narrowing income gap between the rich and poor and greater access to health insurance has effectively reduced income inequality, equalizing access to care. This suggests that the most effective way to reduce the inequity is to narrow the gap of income between the rich and poor while adopting social risk protection.

RESUMEN

OBJECTIVE: To estimate the health-related economic costs attributable to smoking in China for persons aged 35 and older in 2003 and in 2008 and to compare these costs with the respective results from 2000. METHODS: A prevalence-based, disease-specific approach was used to estimate smoking-attributable direct and indirect economic costs. The primary data source was the 2003 and 2008 China National Health Services Survey, which contains individual participant's smoking status, healthcare use and expenditures. RESULTS: The total economic cost of smoking in China amounted to $17.1 billion in 2003 and $28.9 billion in 2008 (both measured in 2008 constant US$). Direct smoking-attributable healthcare costs in 2003 and 2008 were $4.2 billion and $6.2 billion, respectively. Indirect economic costs in 2003 and 2008 were $12.9 billion and $22.7 billion, respectively. Compared to 2000, the direct costs of smoking rose by 72% in 2003 and 154% in 2008, while the indirect costs of smoking rose by 170% in 2003 and 376% in 2008. CONCLUSIONS: The economic burden of cigarette smoking has increased substantially in China during the past decade and is expected to continue to increase as the national economy and the price of healthcare services grow. Stronger intervention measures against smoking should be taken without delay to reduce the health and financial losses caused by smoking.

RESUMEN

OBJECTIVE: To understand the epidemiology of non-fatal injuries among adults aged 65 years and older in China. DESIGN: Cross-sectional survey (the Fourth National Health Services Survey of China). PARTICIPANTS: Urban and rural residents aged 65 years and older from 56,400 households in China. MAIN OUTCOME MEASURES: The incidence rate was calculated as the number of persons injured in the previous 12 months divided by the population x 1000. RESULTS: The incidence rate of non-fatal injuries among elderly individuals in the previous 12 months was 37.5 per 1000 population. Home, street, working environment, and public buildings were the most common places of occurrence, accounting for more than 90% of injuries. Falls were the leading cause of non-fatal injuries. After adjusting for other factors, Han people were 39% more likely to be injured than non-Han people, and the divorced and the widowed were found to have, respectively, 4.6 and 2.2 times the risk of injury compared with single persons, p<0.05. Education, per capita household income and urbanisation did not significantly affect the injury risk when confounding factors were controlled for. CONCLUSION: Almost 4% of adults aged 65 years and over sustain injuries each year in China. Falls should be a priority of injury prevention for elderly people, efficient home injury prevention programmes need to be developed, and the divorced and widowed should be targeted as groups at high risk of injury.

RESUMEN

UNLABELLED: To compare the sampling errors from cluster or unequal probability sampling designs and to adopt the unequal probability sampling method to be used for death surveillance. Taking 107 areas from the county level in Shaanxi province as the sampling frame, a set of samples are drawn by equal probability cluster sampling and unequal probability designs methodologies. Sampling error and effect of each design are estimated according to their complex sample plans. Both the sampling errors depend on the sampling plan and the errors of equal probability in stratified cluster sampling appears to be less than simple cluster sampling. The design effects of unequal probability stratified cluster sampling, such as piPS design, are slightly lower than those of equal probability stratified cluster sampling, but the unequal probability stratified cluster sampling can cover a wider scope of monitoring population. CONCLUSIONS: Results from the analysis of sampling data can not be conducted without consideration of the sampling plan when the sampling frame is finite and a given sampling plan and parameters, such as sampling proportion and population weights, are assigned in advance. Unequal probability cluster sampling designs seems to be more appropriate in selecting the national death surveillance sites since more available monitoring data can be obtained and having more weight in estimating the mortality for the whole province or the municipality to be selected.

RESUMEN

OBJECTIVE: For the purpose of establishing electronic health record (EHR), business-oriented health data distributed in different systems should be integrated to focus on individuals. This study is aimed at collecting health data items that are now nationally available in various health information systems, and harmonizing them by modeling and defining the data elements. METHODS: This study followed a bottom-up strategy in data standard development. Health data items were identified and collected by referring to national health service regulations, consulting domain experts and performing field investigations. Data items were classified and modeled based on recognized domain knowledge, information standards and specifications developed by standard development organizations (SDOs) of other countries. Data elements were extracted from data items and defined according to ISO/IEC 11179 -Metadata registries (MDR) and confirmed needs. RESULTS: 1588 data items were collected from 33 recording forms that have been used nationally in health services, and were classified with a conceptual data model that was composed of 7 super classes (healthcare clients, healthcare providers, birth registry, health event/act, healthcare process, death, and others) and 15 classes (person's identification, person's socio-demographic characteristics, address, communication, provider-organization, provider-individual, birth, health event/act, observation, procedure, drug and material administration, recommendation, evaluation, expenditure, death, others). By normalizing the concepts and representations of data items, data elements were derived and defined as the attributes of classes in the data model. Data items were specified as instances of corresponding data elements. CONCLUSIONS: A large number of health data have been collected nationwide but person's life-long health record is incomplete and inconsistent now. To integrate such massive quantity of health data from various sources, a conceptual data model was established to organize data items, avoiding conflicts and duplications in between. For data consistency, data elements should be extracted from the data items and defined as attributes of classes in the data model by choosing essential metadata attributes. Treating data items as instances of well defined data elements might make data in different contexts manageable and agreeable. To be semantically unambiguous, further study should be performed to deal with the standardization of detailed medical information, and perfect the approach of data harmonization.

RESUMEN

OBJECTIVE: To investigate the impact of high plasma LDL-C level with or without metabolic syndrome (MS) on the incidence of stroke in Chinese adults. METHODS: Totally 42 626 subjects (25-75 years old) from Chinese National Health and Nutrition Survey in 2002 were stratified four groups based on plasma LDL-C level:<2.00 mmol/L group, 2.00-2.50 mmol/L group, 2.51-3.31 mmol/L group, and >or=3.32 mmol/L group. The prevalence of MS (with 2005 International Diabetes Federation criteria) and stroke and the risk factors of stroke were compared among the four groups. RESULTS: (1) The prevalence of MS and stroke increased with rising of LDL-C level. The prevalence of MS in LDL-C>or=3.32 mmol/L group increased 2.5 times (7.9% vs 20.1%) as compared with that in LDL-C<2.00 mmol/L group and the prevalence of stroke increased 4.2 times (0.5% vs 2.1%), all P<0.01. (2) In subjects with similar LDL-C level, the prevalence of stroke was significantly higher in a subgroup with MS than that without (P<0.01). (3) After adjustment for age, sex and smoking, logistic regression analysis showed that both LDL-C level and MS were positively associated with the development of stroke; the odds ratio (OR) was 2.35 and 3.15 (P<0.0001), respectively. (4) Compared with the subgroup of LDL-C<2.00 mmol/L without MS, OR for stroke in the subgroups of LDL-C 2.00-2.50 mmol/L, 2.51-3.31 mmol/L, and >or=3.32 mmol/L without MS was 1.03, 1.89, and 2.08, whereas the OR for stroke in the subgroups with MS and similar level of LDL-C was 4.38, 5.23 and 6.15; this indicated that the risk of stroke in subjects with MS increased by 3-4 times compared with subjects without (P<0.0001). CONCLUSION: Both high LDL-C level and MS are independent risk factors of stroke, but the risk of stroke will be further increased in the presence of high LDL-C level plus MS. It is suggested that combined intervention therapy of LDL-C and MS will play an important role in the prevention of stroke.

RESUMEN

OBJECTIVE: To assess the capacity for logistics, public education, and training in managing public health emergency in China at present. METHODS: Four provinces were selected using stratified sampling. All the municipalities of these 4 provinces were assessed using the 9th and 10th subscales (logistics, public education and training) of Preparedness and response capacity questionnaire for public health emergencies for provincial or municipal governments developed by the Center for Health Statistics and Information, Ministry of Health of China. RESULTS: Sixty of the 66 questionnaires (90.91%) were collected. Among the 60 investigated municipalities, 80% established a specific agency to take charge of emergency material storage, management and allocation, 65% developed standard for material storage, 35% developed standard of places for material storage, 25% built regulation for testing, maintaining, and updating the emergency materials regularly, 45% arranged budget for routine payment, 27% established standard of emergency fund, and 28% set up the procedure to initiate emergency fund. The average of standard score of subscale 9 was 43.33 (95% confidence interval, 35.65~51.01). 25% of the 60 municipalities conducted assessment for training in the past 2 years, 53% developed plan for emergency personnel training, 20% developed effectiveness assessment regulation of emergency personnel training, 80% assigned a specific agency to be responsible for public education, and 23% established regulation for public education. The average of standard score of subscale 10 was 47.43 (95% confidence interval, 40.69~54.17). CONCLUSION: Serious problems are found in logistics, public education, and training for public health emergency management in China. Measures should be taken immediately by the central and local government to improve these capacities.
