    The measurement of health has been developed from mortality-based to focus on length of life such as life expectancy, then the focus has been redirected to healthy life expectancy (HLE) globally, one measure reflecting the quality of life. The year-over-year increase in average HLE has been set by China as a national goal to be achieved during the 14th Five-Year Plan period (2021—2025) . In this article, we briefed the measurements of HLE, and reviewed the experience measuring and using the HLE in international organizations and selected countries. With consideration of the development of health statistics and information system of China, we proposed Global Activity Limitation Index (GALI) as the measurement method of HLE and goal value of HLE, including the share of HLE in life expectancy as well additional year of HLE achieved by the end of 2025. In addition, we concluded as suggestions for achieving the goal.

    Patient-reported outcome (PRO) can provide evidence for medical decision making, health care policy development, and also serve as symptom parameters for condition monitoring to provide timely care targeting personal needs. With the widespread applications of PRO in clinical research, related ethical issues have received deeply attention. Published in 2022, the Ethical Considerations for the Inclusion of Patient-Reported Outcomes in Clinical Research (the PRO Ethics Guidelines) , is an important consensus-based reference developed for addressing ethical considerations of PRO in clinical research. Addressing ethical issues in PRO can improve the quality of PRO data while minimizing the risk, burden, and harm to participants and protecting the rights of participants and researchers. We interpreted the guideline, aiming to provide a guide for colleagues addressing ethical issues of PRO, and to increase their attention to these issues.

    Patient-reported outcome (PRO) refers to any information about the patient's own health condition, functional status, and feelings about treatment that directly comes from the patient without interpretation by physicians, nurses or anyone else. Measuring outcomes from the patient perspective is conducive to improving the quality of medical services and treatment satisfaction. We summarized recent applications of PRO in many fields, such as drug review and approval, drug and medical equipment supervision, quality evaluation of medical services, health technology assessment, and comprehensive clinical evaluation of drugs, and reviewed the latest advances in research on PRO, such as the development of PRO instruments, the construction of a health state utility value set, the health measurement in children and adolescents, and the quality evaluation of PRO instruments. Then we put forward recommendations to further promote the studies and use of PRO in China: strengthening the development of PRO instruments applicable to China, valuing the use of PRO in clinical practice, enhancing the interdisciplinary research on PRO, broadening the profile of research on PRO, and intensifying relevant research.

    Background

    AIDS is a very hazardous infectious disease. The analysis of AIDS incidence and mortality trends and the age-period-cohort influence on them, may provide insights into the formulation of AIDS related prevention and control policies.

    Objective

    To assess AIDS incidence and mortality trends, and the impact of age, period and cohort on the incidence and mortality of AIDS in China from 2004 to 2018.

    Methods

    In March 2022, from the online direct reporting system of the Data-center of China Health Science, number of AIDS patients, AIDS incidence, number of patients dying of AIDS, AIDS mortality in China during 2004—2018 were extracted from the overall information during the period. The Joinpoint regression model was used to estimate the trend of AIDS incidence and mortality, and to calculate the annual percent change (APC) and average annual percent change (AAPC) . The age-period-cohort model was used to assess the influence of age, period and cohort on the trend of AIDS incidence and mortality.

    Results

    During the period from 2004 to 2018, the incidence of AIDS in China increased from 0.248 9/100 000 to 4.956 9/100 000, and AIDS mortality increased from 0.060 5/100 000 to 1.431 2/100 000. Joinpoint regression analysis revealed that the incidence and mortality of AIDS in China had an average annual increase of 22.70%〔95%CI (20.70%, 24.80%) 〕and 18.80%〔95%CI (12.10%, 25.90%) 〕in the period, respectively (P<0.05) . The age-period-cohort analysis indicated that age, period and cohort all affected AIDS incidence and mortality (P<0.05) . The temporal trend in age-specific AIDS incidence or mortality showed a J-shaped curve of growth. The AIDS incidence increased from 0.000 4/100 000 in 5-9-year-olds to 2 828.828 5/100 000 in 75-79-year-olds, and the AIDS mortality increased from 0.000 4 in 5-9-year-olds to 740.297 4 in 75-79-year-olds. With the passage of time, the risk of AIDS incidence and mortality increased gradually: compared with the rate ratio of AIDS incidence and mortality (RR=1.000 0) in 2009—2013, the RR of AIDS incidence increased from 0.315 6〔95%CI (0.277 2, 0.359 4) 〕during 2004—2008 to 2.024 4〔95%CI (1.877 1, 2.183 2) 〕during 2014—2018. The RR of AIDS mortality increased from 0.329 1〔95%CI (0.291 7, 0.371 3) 〕in the period 2004—2008 to 1.522 6 in the period 2014—2018. The later the cohort was born, the greater the risk of AIDS incidence and mortality: compared with the relative risk of AIDS incidence and mortality (RR=1.000 0) in 1969—1973 cohort, the RR of AIDS incidence increased from 0.000 1〔95%CI (0, 0.000 4) 〕in the 1929—1933 cohort to 471.385 3〔95%CI (118.524 3, 1 874.755 6) 〕in the 2009—2013 cohort; the RR for mortality increased from 0.000 1 〔95%CI (0, 0.000 6) 〕in the 1929—1933 cohort to 93.634 5〔95%CI (21.168 0, 414.182 4) 〕in the 2009—2013 cohort.

    Conclusion

    AIDS incidence and mortality were on the rise in China during 2004—2018. AIDS incidence and mortality increased with age, and the period and cohort effects on the risk of incidence and mortality increased. More efforts need to be made to strengthen AIDS prevention and treatment in middle-aged and elderly people.

    Background

    As intestinal infectious diseases are one major public health issue in China, there remains an urgent need to dynamically track the incidence trend and epidemiological characteristics of these diseases on the whole or by category.

    Objective

    To analyze the epidemiological characteristics, spatial distribution and clustering features of types A and B intestinal infectious diseases in China from 2008 to 2018, providing a theoretical basis for optimizing the prevention and control strategies of these two types of diseases.

    Methods

    Data on the incidence of types A and B intestinal infectious diseases〔including typhoid and paratyphoid, viral hepatitis (hepatitis A, hepatitis E and undifferentiated type of hepatitis) and dysentery〕in all regions of China (n=31, except for Hong Kong, Macao and Taiwan) from January 2008 to December 2018 were extracted in March 2022, using the Data-center China Public Health Science as the data source. The chi-square test for trend was used to examine the temporal trend of incidence of these two types of diseases. Descriptive epidemiology, spatial autocorrelation, and spatial and temporal clustering analysis were used to analyze the spatio-temporal epidemiological characteristics of the diseases, and to determine the key seasons and regions for epidemic prevention and control.

    Results

    A cumulative total of 3 220 480 cases of types A and B intestinal infectious diseases were reported in China from 2008 to 2018, with an average annual incidence rate of 7.25/100 000, showing a decline in overall incidence rate (P<0.05) . The incidence rate of typhoid and paratyphoid, viral hepatitis and dysentery demonstrated a downward trend during the period (P<0.05) . The incidence rate of typhoid and paratyphoid decreased from 1.18 per 100 000 population in 2008 to 0.78 per 100 000 population in 2018. The incidence rate of viral hepatitis decreased from 9.81 per 100 000 population in 2008 to 4.34 per 100 000 population in 2018. The incidence rate of dysentery decreased from 23.65 per 100 000 population in 2008 to 6.56 per 100 000 population in 2018. Typhoid, paratyphoid and dysentery occurred more frequently in summer and autumn (from May to October) , while the incidence of viral hepatitis had no obvious changes across seasons. The spatial distribution map of types A and B intestinal infectious diseases in China indicated that, typhoid and paratyphoid had a high incidence rate in Yunnan, Guizhou and Guangxi in western China, viral hepatitis showed a high incidence rate in western China, and dysentery had a high incidence rate in Beijing and Tianjin. The spatial autocorrelation analysis showed that the incidence rate of typhoid and paratyphoid (except that in 2014) , viral hepatitis (except that in 2016) and dysentery in China over the years from 2008 to 2018 was spatially clustered (global Moran's I ranged from 0.09 to 0.24, P<0.05) . The spatial clustering of typhoid and paratyphoid and viral hepatitis was decreased first and then increased, and that of viral hepatitis declined first and then rose, but was weakened in general. The spatial clustering of dysentery was strong. The spatio-temporal scan statistics detected that Yunnan was the region with the highest incidence rate (the primary geographic cluster) of typhoid and paratyphoid during 2009 to 2013, nine regions with Tibet as the center had the highest incidence rate of viral hepatitis from 2008 to 2011, and Beijing and Tianjin were the regions with the highest incidence rate of dysentery from 2008 to 2012.

    Conclusion

    Having obvious spatial and temporal clustering characteristics, the incidence of types A and B intestinal infectious diseases in China decreased significantly during the period due to effective prevention and control. Our study may be used as a guide to identify key prevention and control areas and to develop prevention and control strategies according to the spatial clustering patterns of different intestinal infectious diseases.

    Background

    Health education and health promotion are at the top of the list of population health promotion strategies. It is essential to provide community-dwelling residents with health education to improve their health literacy. However, few studies focus on the needs of health education (including the contents, acquisition methods and forms) in community-dwelling residents.

    Objective

    To investigate the perceived needs of health education and associated factors in community-dwelling residents, providing a scientific basis for meeting their health education needs and improving their health literacy level.

    Methods

    From January 19 to March 12, 2020, 2 846 residents aged >12 years were selected from 10 cities of China using multistage sampling to attend a questionnaire survey. The questionnaire used contains two parts: the first part is socio-demographic characteristics. And the second part is the perceived health education needs of community-dwelling residents, with 5-point Likert scale items belonging to three dimensions (contents, forms, and acquisition methods) . The total score for each dimension was obtained by summing the score of items in the dimension. Residents' needs of the contents, forms or acquisition methods were graded as "low", "moderate", or "high" by the average total score of each dimension. Univariate and multivariate ordinal Logistic regression were used to explore the associated factors of level of health education needs in community-dwelling residents.

    Results

    Altogether, 2 679 cases (94.13%) who handed in responsive questionnaires were finally included. The average total score for dimensions of contents, acquisition methods and forms were (21.49±5.91) , (15.11±5.48) and (13.61±4.41) , respectively. Among the content items of health education, the top three relatively strongly needed/strongly needed were food safety〔2 081 (77.68%) 〕, disease prevention and control〔2 020 (75.44%) 〕, and rational medication〔1 963 (73.28%) 〕. Among the acquisition methods of health education, the top two relatively strongly needed/strongly needed were health education columns in the community built using digital media technologies〔1 519 (56.70%) 〕 and interactive health education〔1 518 (56.66%) 〕. In terms of the health education form, the proportions of residents who needed various forms of health education were similar. Specifically, the proportion of residents who relatively strongly needed/strongly needed video-based health education was the highest〔64.91% (1 739/2 679) 〕, while that of residents who relatively strongly needed/strongly needed written health educational materials was the lowest〔50.84% (1 362/2 679) 〕. Multivariate ordinal Logistic regression analysis showed that age and current occupation were associated with residents' needs of the content of health education (P<0.05) . Moreover, gender, the highest educational attainment, current occupation, and current place of residence were associated with residents' needs of methods for acquiring health education (P<0.05) . And age, the highest educational attainment, current occupation, and current place of residence were associated with residents' needs of the form of health education (P<0.05) .

    Conclusion

    Community-dwelling residents showed high demand for the contents, acquisition methods, and forms of health education, which presented a diversified trend. They paid special attention to the content about food safety and disease prevention and treatment, and preferred interactive and video-based health education in terms of form.

    Background

    As population ageing accelerates and life expectancy increases, multimorbidity and disability pose challenges to health and social care systems worldwide. Although multimorbidity is closely related to disability, there is still a lack of research on the impact of multimorbidity on disability in rural middle-aged and elderly people.

    Objective

    To evaluate the influence of multimorbidity on disability in rural middle-aged and elderly people using the propensity-score matching (PSM) , providing a reference for formulating strategies for the management of multimorbidity and disability in this population.

    Methods

    The data of 11 088 rural middle-aged and elderly people (≥45 years old) were collected from the 2018 China Health and Retirement Longitudinal Study in March 2022, including demographics, chronic disease prevalence, and disability measured by activities of daily living (ADLs) , and instrumental activities of daily living (IADLs) . Participants were divided into multimorbidity and non-multimorbidity groups by the prevalence of multimorbidity (defined as having ≥2 chronic conditions) , and then matched using PSM with a 1∶1 ratio. Conditional Logistic regression model for paired binary data was used to assess the impact of multimorbidity on ADL disability and IADL disability.

    Results

    Of 11 088 ural middle-aged and elderly people with chronic diseases, 2 711 (24.45%) had ADL disability, 4 216 (38.02%) had IADL disability, and 7 673 (69.20%) were multimorbidity patients. The prevalence of ADL disability or IADL disability differed significantly by gender, age, marital status, education level, sleep duration, smoking, drinking, disability status, participation in social activities, and prevalence of multimorbidity (P<0.05) . There were statistically significant differences in gender, age, marital status, education level, sleep duration, smoking, drinking, disability status, and participation in social activities between the two groups before matching (P<0.05) . A total of 3 391 pairs were derived after PSM with matched covariates. Logistic regression analysis showed that multimorbidity prevalence increased the risk of ADL disability by a factor of 2.25〔OR (95%CI) =2.25 (1.96, 2.59) , P<0.001〕 and elevated the risk of IADL disability by a factor of 1.52〔OR (95%CI) =1.52 (1.36, 1.71) , P<0.001〕.

    Conclusion

    PSM is beneficial for reducing confounding bias in study groups. Multimorbidity would increase the risk of disability in rural middle-aged and elderly people. It is suggested to value the government input on resources and policies to strengthen the prevention and management of multimorbidity and disability in this group of people.

    Background

    Population aging is getting worse in our country. Family doctor contract service plays an important role in boosting the construction of hierarchical diagnosis and treatment system and establishing a reasonable and orderly medical order. Current research about family doctor contract service policy mainly focus on qualitative evaluation, and there are few researchers use tools to quantitatively evaluate each individual representative policy.

    Objective

    This study aims to quantitatively evaluate the pros and cons of six Chinese central government policies about family doctor contract service, thus, proposing strategies and measures to promote the high-quality development of our country's family doctor contract service, and helping the construction of healthy China.

    Methods

    We searched Peking University's PKULAW.com and websites of some relevant ministries of the State Council of China from January 1, 2015 to April 30, 2022. The key word was "family doctor". The software ROSTCM 6.0 was used for text mining. Based on the results, this study selected central government policies about family doctor contract services, then used the PMC index model to quantitatively evaluate these policies.

    Results

    This study included thirty-two policies based on inclusion and exclusion criteria. The top five high-frequency keywords in the field of family doctor services are "contract service" (n=274) , "health" (n=272) , "medical" (n=264) , "family doctor" (n=225) , and "contract" (n=180) . They were marked as P1-P6, respectively. In terms of methods and other aspects, the scores of each dimension are relatively high. The results of quantitative evaluation showed that the ranking of policies is P1>P3>P2>P6>P4>P5. Three policies were rated as excellent, the other three were rated as acceptable. The scores were relatively high in the policy content, policy nature, policy evaluation, policy field and policy role.

    Conclusion

    Our country's family doctor contract service policy had a relatively broad content and is relatively mature. It is suggested to pay attention to the combination of long-term, medium-term and short-term validity of the policies, improve incentive approaches from multiple perspectives, enhance the sense of professional honor of family doctors, and use a variety of policy tools and policy action.

    Promoting contracted family doctor services is an important way to implement tiered diagnosis and treatment, and to safeguard people's health, as well as a cornerstone of achieving Health China 2030 goals. However, the development of this system is constrained by some problems, such as contracting a family doctor but making no appointments. Many countries have introduced competition mechanisms in the supply of contracted services in different degrees to enhance the quality of family doctor services. However, China is now lack of theoretical and empirical studies about introducing competition mechanisms inthe delivery of contracted family doctorservices. We reviewed the latest developments in theoretical and empirical studies involving the use of competitive mechanisms in the provision of contracted family doctor services, which will contribute to the study and implementation of family doctor system in China.

    Background

    With the continuous progress of the New Medical Reform, contracting service by family physicians has increasingly become an important guarantee for the basic medical care and health of the people, and the agreements of family doctors' contracting service has become the premise of achieving "everyone has a family doctor". However, the standardization and binding force of the agreement still remain to be studied.

    Objective

    By analyzing the agreements of family doctors' contracting services, we expected to further standardize the contracting services and improve the standardized management level of the services contracted by family doctors.

    Methods

    According to the purpose of the survey, the contracting agreements of the 14 community health service centers were finally selected as subjects by random sampling among 1-3 community health service centers in each of the nine main districts of Chongqing in July 2021. The main analysis framework was based on the contracting subject, contracted service, contracting fee mechanism, and the rights and obligations of the contracting subject. Finally, descriptive analysis of the agreements was performed by means of content analysis.

    Results

    When compared the agreements in different districts, the contents of basic medical services and basic public health services were relatively similar (basic medical services included diagnosis and treatment services for common diseases, frequently occurring diseases and traditional Chinese medicine, etc., and basic public health services included establishing resident health files, providing health consultation, and vaccination, etc.) . There were differences in the terms of years of service, personalized services, etc. among family doctors in different regions of Chongqing: there were 12 agreements that specified a binding period of 1 year, 1 agreement whose duration was decided by the parties, and 1 agreement that did not specify the binding period. Among all agreements, the definition of the rights and obligations of contracting subjects and parties was vague. Among them, contracting subjects of 6 agreements included community health service centers, superior guidance hospitals, family doctors and representatives of heads of households or family representatives, 6 agreements included community health service centers, family doctors and representatives of heads of households or family representatives, 1 agreement included community health service centers and household heads, and 1 agreement did not specify the contracting subject.

    Conclusion

    It is necessary to further clarify the objects and agreements of contracting service, and improve the rights and obligations of the contracting subjects in Chongqing. Combined the experience of implementation of contracting services by family doctors of various regions, it is necessary to improve the performance effectiveness and the quality of the contracted services, and promote the implementation and development of the family doctors' contracting services.

    Background

    There is an issue of mismatch between supply and demand of medical care resources in China. The implementation of contracted family doctor services is an effective measure to address the issue, and to improve the hierarchical diagnosis and treatment system. Therefore, it is urgent to speed up the training and ensure the training quality of general practice workforce.

    Objective

    To develop a comprehensive and systematic general practitioner (GP) competency model after analyzing the concept and structural domains of competencies (including inner competencies) required for GPs to deliver contracted healthcare services, providing insights into the realization of training eligible GPs in terms of quantity and quality, and the improvement of quality and efficiency of contracted services.

    Methods

    From December 2020 to September 2021, we conducted in-depth, semi-structured interviews with 38 GPs from 10 medical institutions in four cities (Zhenjiang, Taizhou and Suzhou in Jiangsu Province, and Foshan in Guangdong Province) , then treated the interview results applying the three-level coding and theoretical saturation used in the grounded theory. After that, we developed a General Practitioner Competency Model.

    Results

    The model consists of 10 items, which belong to four domains: general care capability, humanistic practice capability, team cooperation capability, learning and development capability. General care capability and learning and development capability belong to external competencies, which represent the external performance and driving force of competencies, and determine the level of competencies of GPs to provide contracted services. Humanistic practice capability and team cooperation capability reflect the internal traits and competencies, which belong to the inner competencies, and determine the potential of GPs to provide contracted services.

    Conclusion

    The model developed by us is complete and comprehensive, in which the inner competencies of GPs have been fully explored, which may be contributive to the training of GPs delivering contracted services, and to the development of a GP competency assessment system using quantitative empirical methods.

    Background

    General practitioners (GPs) play a major role in providing essential medical services. Most of the existing research on GPs' competencies emphasizes that efforts should be made to improve the medical knowledge and skills of GPs, ignoring the importance of their inner competencies. And there is no scale for effective measurement of GPs' inner competencies in China. Thus, developing a assessment scale of GPs' inner competencies is of great significance for improving the quality of essential medical services.

    Objective

    To develop an inner competency rating scale for GPs and to assess its psychometric properties, providing certain reference for improving GPs' competencies.

    Methods

    By use of literature review and behavioral event interviews results, the draft of the General Practitioner Inner Competency Rating Scale (GPICRS) was developed. Then in September to December 2021, the draft was tested by a survey with a national random sample of 380 (88.2%) GPs. Its rationality was verified by item purification, exploratory factor analysis, confirmatory factor analysis and reliability and validity tests. The weighted average method was used to evaluate the inner competency of GPs. The total and dimensions scores of the GPICRS were compared by demographics.

    Results

    Three hundred and thirty-five GPs who returned responsive questionnaires were included for analysis. The formal scale consists of 14 items in 4 dimensions: work motivation, self-efficacy, medical humanities and professional qualities. The value of KMO (0.737) and result of Bartlett's Test of Sphericity (χ2=592.715, P<0.001) derived from the exploratory factor analysis, suggested that the data sample was appropriate for factor analysis. Four common factors with an eigenvalue >1.000 were extracted, and the percent of total variance explained by which was 58.861%. The results of confirmatory factor analysis showed that the fitting indicators of the four-factor model were acceptable (χ2/df=2.834, RMSEA=0.074, GFI=0.922, PGFI=0.623, NFI=0.889, TLI=0.903, CFI=0.924) . When it comes to the formal scale, the Cronbach's α was 0.851. The Cronbach's α for each of its dimensions ranged from 0.757 to 0.809. The standardized regression coefficient of each item was greater than 0.500, and the AVE for each dimension was above 0.500. And the CR value for each dimension was greater than 0.700. The arithmetic square root of AVE was greater than the correlation coefficient between the factors. The average total GPICRS score of the 335 GPs was 4.15, which was at a good level, and GPICRS score varied across GPs by different characteristics (gender, age group, professional title, etc.) .

    Conclusion

    Our GPICRS could effectively evaluate the inner competency of GPs, which may contribute to the decision-making in primary care and the personal development of GPs. In the future, efforts can be made to improve the comprehensive capability of GPs from the following four aspects: self-cognition and occupational identity, theoretical knowledge and practical application, professional ability and work attitude, organizational support and social recognition.

    Background

    The competencies of general practitioners (GPs) have become a basis for promoting the implementation of tiered diagnosis and treatment, and effective supply of primary healthcare services against the backdrop of the initiation and implementation of contracted services provided by GPs in primary care in China. The regular competency-based assessment systems with clear objectives and strong operability can positively stimulate GPs to provide contracted services with higher quality and efficiency.

    Objective

    To develop a competency rating scale for GPs, providing a tool applicable to scientific evaluation of GPs' competencies in China.

    Methods

    By use of a GP competency model, and review results of relevant studies and competency scales, the measurement items and the draft of the scale were developed, then were revised according to the results of a questionnaire survey conducted with GPs in primary care in major provincial administrative regions from April to August 2021. Among the 402 responders, the answers of 201 cases (sample A) were used for exploratory factor analysis, and those of the other 210 cases (sample B) were used for confirmatory factor analysis. Based on this, the reliability and validity of the final scale were tested.

    Results

    The final General Practitioner Competency Rating Scale includes four dimensions (general service competency, humanistic competency during practice, teamwork and cooperation competency, learning and development competency) and 21 items. The Cronbach's α for the scale, and the afore-mentioned four dimensions was 0.929, 0.877, 0.850, 0.812, and 0.811, respectively. The P-value of Bartlett's test of sphericity was less than 0.001 (approximate χ2=2 319.759, P<0.001) , reaching a significant standard, and the KMO value (0.923) was close to 1.0. By exploratory factor analysis, four common factors were extracted, explaining 67.680% of the total variance. The first-order confirmatory factor analysis showed that the correlation coefficients of the four dimensions were between 0.68 and 0.72, and highly correlated. The second-order confirmatory factor analysis results were: χ2/df=1.312, RMSEA=0.039, CFI=0.976, GFI=0.913, NFI=0.907.

    Conclusion

    Our scale has proven to have good reliability and validity, which may be used for assessing the competencies of GPs delivering contracted services in China.

    Background

    The training of targeted admission medical students (TAMS) is an important measure to alleviate the shortage of primary care physicians and to improve the overall quality and level of primary care workforce in rural China.

    Objective

    To explore the recent hot topics, present and future trends in the research on TAMS in China, so that a solid theoretical foundation can be laid for future studies.

    Methods

    All articles about the training of TAMS published from January 1, 2010 to December 31, 2021 in three databases (i.e., CNKI, WanFang Data and CQVIP) were searched on February 15, 2022. The number of the articles was counted for analysis. CiteSpace was used to conduct a visualization analysis of authors, research institutions and keywords extracted from the identified articles.

    Results

    A total of 598 articles were finally included. The annual number of publications demonstrated an increasing trend generally during the period, with a peak in 2018 (n=81) . Five major groups of authors were identified. The top three prolific institutions were Gannan Medical University〔113 articles (18.9%) 〕, Guangxi Medical University〔40 articles (6.7%) 〕 and Xinxiang Medical University〔28 articles (4.7%) 〕. The top three high-frequency keywords were "order-oriented" (70 times) , "targeted admission students" (57 times) and "talent cultivation" (44 times) . Eight topic clusters were derived from keyword cluster mapping, namely "#0 learning motivation" "#1 teaching model" "#2 order-oriented cultivation" "#3 influencing factors" "#4 general medicine" "#5 primary care" "#6 medical college" and "#7 medical students". Knowledge map of keywords with the strongest citation bursts showed that the top three were "career identity" "major identity" and "rural primary care". The time-dependent graph indicated that the evolution of research on the training of TAMS could be roughly divided into three stages: education and training for TAMS at school, post-graduation training and education of TAMS, and current work status of TAMS in primary care.

    Conclusion

    The research on the training of TAMS in China is increasingly flourishing. Relevant policies are the major facilitators for the training of TAMS. The research is also featured by lack of inter-regional and inter-institutional coordination among related research institutions and authors. Moreover, the hotspots are constantly changing with the times, and the major topics about which can be summarized as follows: training models for TAMS, learning motivation of TAMS, and intention to work at primary care and associated factors in TAMS. The future research directions may be the evaluation of current work status and intention to work at primary care in a long-term period in TAMS, effectiveness of the implementation of policies related to the training of TAMS, and the innovative development of training models for TAMS.

    Background

    The program of targeted medical education program has been carried out since 2010 in China, aiming to train general medical talents working in primary care. Further research is needed to explore the working status and career planning in targeted admission medical graduates (TAMG) , as well as the overall assessment for them by the employing unit.

    Objective

    To comprehensively understand the working status (competencies, satisfaction, intention to improve professional capabilities) , career planning, retention intention and associated factors after fulfilling the preadmission commitments in TAMG working in Hainan's primary care after completing the "5+3" standardized general residency program, providing a basis for the optimization of incentive policies for training and retaining general practitioners (GPs) , and for medical colleges to determine the orientation and development direction of a general practice school (department) .

    Methods

    From April 25 to May 6, 2021, by use of cluster sampling, 615 GPs (including 309 TAMG trained with the "5+3" standardized general residency program who work as a GP in primary care after graduation, 56 assistant GPs trained with the "3+2" program, and 250 GPs trained with general medicine before shifting to the post) were selected from 19 cities (counties) in Hainan Province to attend a self-administered questionnaire survey for collecting information about their capabilities, satisfaction and intention to improve professional capabilities. At the same time, 1 574 leaders and colleagues of the TAMG were invited to evaluate the capabilities of the TAMG. The factors influencing the retention intention of the TAMG after fulfilling their preadmission commitments in primary care were analyzed by binary Logistic regression. For further understanding the working status, life and thoughts on the job of the TAMG, the offline research team of this study conducted field investigation in three primary hospitals (one in Haikou, one in Qiongzhong, and one in Sanya) , and held a group discussion with directors of health committees of Haikou, Qiongzhong and Sanya, and directors of the three primary hospitals, as well as 38 randomly selected TAMG from May 7 to 8, 2021.

    Results

    TAMG had lower mean score of self-rated capabilities than assistant GPs trained with the "3+2" program〔 (19.31±2.59) vs (20.46±2.72) 〕, and GPs trained with general medicine before shifting to the post〔 (19.31±2.59) vs (20.77±2.73) 〕 (P<0.05) . TAMG had lower mean score of self-rated job satisfaction than assistant GPs trained with the "3+2" program〔 (39.77±4.66) vs (41.59±4.56) 〕, and GPs trained with general medicine before shifting to the post〔 (39.77±4.66) vs (41.10±5.19) 〕 (P<0.05) . TAMG had lower mean score of self-rated intention to improve professional capabilities than GPs trained with general medicine before shifting to the post〔 (7.80±2.25) vs (9.10±3.17) 〕 (P<0.05) . However, the mean score of capabilities of TAMG rated by TAMG' leaders and colleagues was higher than that rated by themselves〔 (20.29±3.43) vs (19.31±2.59) 〕 (t'=5.735, P<0.001) . One hundred and fourteen of TAMG (36.89%) intended to stay on after the expiration of the contract. The main factors affecting their retention intention were professional title, current income, and wanting to be a GP (P<0.05) . According to the group discussion, TAMG had high level of enthusiasm at their work and a great sense of team spirit. Moreover, more than half of them had a clear career plan. The challenges faced by TAMG in primary care were the following: overall low level of remuneration, unsatisfactory working environment, insufficient understanding and insufficient understanding and undervaluing of GPs and general practice in relevant administrative departments, inadequate implementation of relevant policies, and limited conditions in primary care hindering the acquisition of the latest advances in general medicine and continuing education.

    Conclusion

    The TAMG had high levels of capabilities and job statistician, but low level of intention to improve professional capabilities and to stay on after the expiration of the contract. Their capabilities were recognized by their leaders and colleagues. The implementation of incentive policies was un-ideal in Hainan, which may be due to satisfactory implementation of the incentive system for health talents in primary care. In view of this, it is suggested that relevant departments in Hainan take multiple measures collaboratively to effectively implement the incentive regimen of training and retaining GPs.

    Background

    Diabetes and osteoporosis are common diseases in middle-aged and elderly people. Diabetes can lead to various acute and chronic complications, but its related bone changes are often neglected. Osteoporosis is more common in postmenopausal women, and those with type 2 diabetes mellitus (T2DM) have multiple risk factors for osteoporosis. Therefore, it is particularly important to early identify risk factors of osteoporosis in these women, and to provide them with targeted interventions.

    Objective

    To explore the associated factors of osteoporosis in Chinese postmenopausal women with T2DM through a meta-analysis.

    Methods

    In July 2021, databases of China National Knowledge Infrastructure, CQVIP, WanFang Data, SinoMed, PubMed, EmBase, and the Cochrane Library were searched for literature about factors associated with osteoporosis in Chinese postmenopausal women with T2DM from inception to July 2021. Two researchers independently screened literature and extracted data. RevMan 5.4 and Stata 15.0 were used to conduct a meta-analysis on the data.

    Results

    Twenty-one studies were finally included, from which 11 osteoporosis-related factors were extracted. The meta-analysis showed that age〔MD (95%CI) =6.56 (5.24, 7.88) 〕, years of postmenopause〔MD (95%CI) =5.93 (4.23, 7.62) 〕, duration of diabetes〔MD (95%CI) =1.94 (0.89, 2.98) 〕, body mass index〔MD (95%CI) =-1.99 (-2.63, -1.36) 〕, serum calcium〔MD (95%CI) =0.03 (0.01, 0.06) 〕, fasting blood glucose〔MD (95%CI) =0.49 (0.09, 0.90) 〕, glycosylated hemoglobin〔MD (95%CI) =0.37 (0.02, 0.71) 〕, and fasting insulin〔MD (95%CI) =3.65 (1.24, 6.06) 〕 were associated factors for osteoporosis in postmenopausal women with T2DM. But no significant association was found between osteoporosis and serum creatinine〔MD (95%CI) =4.02 (0.00, 8.04) 〕, serum phosphorus〔MD (95%CI) =0.00 (-0.05, 0.05) 〕, or serum alkaline phosphatase〔MD (95%CI) =1.26 (-0.06, 2.57) 〕 in these women. Sensitivity analysis revealed that the association of all the above-mentioned factors (except for serum creatinine) with osteoporosis was relatively robust.

    Conclusion

    Older age, long years of postmenopause, long duration of T2DM, low levels of BMI and serum calcium, and high levels of fasting insulin, fasting blood glucose, and glycosylated hemoglobin are risk factors for osteoporosis in Chinese postmenopausal women with T2DM. But the effects of serum creatinine, phosphorus, and alkaline phosphatase on osteoporosis in this group need to be further verified.

    Background

    Epidemiological studies have demonstrated that the prevalence of hypertension is higher in postmenopausal women than in elderly men. Increasing attention has been paid to postmenopausal hypertension recently, involving its clinical manifestations, pathological features, pathogenesisand treatment. However, due to disparities in study design, sample size and population characteristics, as well as insufficient resources, the research results of risk factors for postmenopausal hypertension are inconsistent and incomprehensive.

    Objective

    To perform a systematic review of risk factors for postmenopausal hypertension, so as to provide evidence-based basis for better prevention and management of the disease.

    Methods

    From January to May 2022, the databases of CNKI, WanfangData, SinoMed, PubMed, EmBase, the Cochrane Library, and Web of Science were searched for cohort and case-control studies related to risk factors for postmenopausal hypertension from the establishment of the databases to May 20, 2022. Studies were identified using the inclusion and exclusion criteria, then assessed in terms of quality using the Newcastle-Ottawa Scale (NOS) , and those with NOS score≥6 (high quality) were included. RevMan 5.3 was used for meta-analysis.

    Results

    Ten high-quality studies were included, 5 of which were cohort studies, and the other 5 were case-control studies. Overall, 16 potential risk factors for postmenopausal hypertension were identified in a total sample size of 34 864. Meta-analysis showed that the risk factors for postmenopausal hypertension included elevated hs-CRP〔RR (95%CI) =1.38 (1.04, 1.83) 〕, older age〔OR (95%CI) =1.39 (1.11, 1.74) 〕, elevated BMI〔OR (95%CI) =1.61 (1.19, 2.18) 〕, elevated total cholesterol〔OR (95%CI) =1.35 (1.14, 1.59) 〕, elevated triglyceride〔OR (95%CI) =2.17 (1.03, 4.59) 〕, history of diabetes〔OR (95%CI) =1.70 (1.27, 2.27) 〕. The risk-reducing factors included high adiponectin〔RR (95%CI) =0.83 (0.70, 0.99) 〕and advanced menopausal age〔OR (95%CI) =0.90 (0.82, 0.98) 〕.

    Conclusion

    Older age, high levels of hs-CRP, BMI, total cholesterol, and triglyceride, and diabetes are independent risk factors for postmenopausal hypertension. Thus, controlling some of the above controllable factors may effectively decrease the risk of postmenopausal hypertension.
