    Compulsory rural service directed medical student free training program is a medical education policy oriented to the cultivation of high-quality general medical talents for primary care system in rural areas, and is an important initiative to deepen the reform of the pharmaceutical and health system and accelerate the construction of a "healthy China", which is an important foundation for implementing the "poverty removal" and promotion of sustainable development of "poverty alleviation by health". Policy of compulsory rural service directed medical students free training program was designed scientifically and rationally, effectively combining motivating mechanisms with compulsory mechanisms, and is continuously refined in the practice process. In the course of policy implementation, various regions of our country have developed their characteristic implementation strategies accordingly in the links of enrollment, training, employment, and contract performance. The program based on the policy educated a large number of qualified GPs for rural primary care system. The compulsory rural service directed medical students fulfilled the contract well, and the career development trend was positive, which contributed to strengthening the construction of the primary health workforce, enhancing the level of primary health service, and promoting the establishment of a hierarchical diagnosis and treatment system. However, during the implementation of the policy, many challenges have been encountered, such as some students' low learning enthusiasm during the training period, limited capacity of local authorities to implement the policy, the need for improvement of pay incentives for primary GPs and the short service cycle. In this paper, we conducted a systematic analysis of the design concept and execution process of the policy of free training for compulsory rural service directed medical students, and suggested that further expansion of scale of the compulsory rural service directed free training program should be conducted to improve the quality of cultivation, enhance the effective collaboration among multiple parties and the contract fulfillment, which will collectively promote the effective implementation of the policy, thereby providing talent support for the hierarchical diagnosis and treatment system and the "Health China" strategy.

    Background

    Our state policy of free training of compulsory rural service oriented medical students (abbreviated as rural service orientation project) starts with the construction of a team of primary medical health talents and makes an excellent contribution to improve the accessibility and quality of medical services in rural areas of China. A comprehensive understanding of the current state of the rural service directed medical student team is important to evaluate the implementation effect of the free training policy, as well as the long-term development of the primary care health talent team.

    Objective

    To review the research progress of related studies on rural service orientation project in China and similar projects abroad, summarize the execution process and execution results of the projects inductively, and compare the similarities and differences between domestic and foreign studies.

    Methods

    The study was conducted from July to September 2021. A literature search for Chinese language was conducted in CNKI, Wanfang Data Knowledge Service Platform and VIP, and the search time was set from 2010-07-01 to 2021-07-01. A literature search in English was conducted in PubMed, web of science, Scopus, and the search time was set from 2000-01-01 to 2021-07-01. Literature screening was performed according to the inclusion and exclusion criteria, relevant information was extracted, and the literature was classified and analyzed according to the subjects and contents of the studies.

    Results

    A total of 443 articles were finally included, with 427 of them on our rural service orientation project in China and the rest 16 on similar projects abroad. The research topics that were studied in the literature included four broad categories: cultivation mode, enrollment, training process, and employment development. In 427 related literatures of China's rural service orientation project: 102 (23.9%) discussed the training mode of rural service oriented project. Ten (2.3%) analyzed the admission status of rural service directed medical students and found that rural service directed medical students had higher awareness rate of the related policies (>75.0%-90.9%) and the proportion of rural students sources was higher (57.6%-84.2%). 270 (63.2%) literatures used the cultivation process of rural service directed medical students as a starting point and focused on their learning situation, professional identification and performance willingness, and found that rural service directed medical students had lower academic performance and professional recognition than general clinical medical students. The results of studies on the performance willingness of rural service directed medical students varied greatly (42.4%-98.4%), and the average performance willingness was 66.2% when weighted by sample size. Only 25 (5.9%) studied employment development in rural service orientated graduates and found an average performance rate of 93.6%. Rural service directed medical students had a faster rate of completing standardized residency training and passing practitioner examination than other five-year clinical graduates. Of the 16 foreign related literatures included, 11 (68.8%) examined the employment development of rural service directed medical graduates and obtained results similar to those of domestic studies.

    Conclusion

    A larger number of current studies focused on rural service oriented project and had rich topics. It was found that the rural service directed free medical student training policy was better implemented, leading to a large number of excellent primary health talents in the Midwest. However, most of the current research focuses on the cultivation stage of rural service oriented medical students, and there is insufficient understanding of medical students who have joined the primary care team at elementary level. Future research should focus on three aspects: performance status after rural service directed medical students having completed the contract period, career development process after employment and the actual role they play in primary health care institutions.

    Background

    To strengthen the construction of health talents team in rural areas, a national compulsory services program (CSP) was started in 2010 in China. In 2015, the state required graduates of the CSP to participate in a 3-year standardized training for residents (residency) upon graduation.

    Objective

    To understand the participation of CSP graduates in residency, analyze the effect of residency on the pass rate of the practicing physician's examination for CSP graduates, and explore the significance of residency on the training of CSP graduates and the rural primary health workforce, so as to provide policy recommendations for the high-quality training of CSP graduates.

    Methods

    Starting in 2015, a cohort of CSP graduates was established from a total of 4 colleges undertaking CSP training programs in 3 provinces in the Midwest of China, and 1∶1 general clinical graduates who graduated the same year were selected as controls and followed up annually. Descriptive analysis was used to show the status of CSP graduates' participation in residency, the pass rate of the examination for practicing physicians, and to compare them with those of general clinical graduates. Stratified Cox regression was used to analyze the effect of attending residency on the pass rate of practicing physician exams.

    Results

    86.69% (228/263), 86.78% (361/416), 87.79% (381/434), 91.08% (388/426), 94.43% (356/377) of the 2015—2019 CSP graduates stated that they were willing to participate in training after graduation, and 72.20% (200/277), 58.75% (151/257), 70.42% (169/240), 73.23% (145/198), 61.03% (83/136) of the same general clinical graduates stated that they were willing to participate in training after graduation. The actual participation proportions of CSP graduates in 2015—2019 in residency were 99.02% (202/204), 97.10% (301/310), 94.99% (322/339), 89.91% (285/317), 69.45% (241/347), 67.57% (100/148), 66.12% (80/121), 74.79% (89/119), 43.33% (39/90), 34.62% (27/78), respectively. The pass rate of practicing physician examination in 2015—2017 CSP graduates reached 99.23% (259/261), 94.86% (351/370), 91.74% (311/339), while the pass rate of same general clinical students was 97.74% (173/177), 95.87% (116/121), 88.24% (105/119), respectively. Cox regression results showed that after adjusting for demographic variables, family economic status, intention of studying medicine, medical education, and factors related to attending the residency, the probability of attending the residency group passing the practitioner's examination was 1.232 times higher than that of not attending the residency group 〔95%CI (1.02, 1.49), P=0.03〕.

    Conclusion

    CSP graduates' willingness to participate in residency training, the proportion of participation, and the pass rate of the qualifying examination for practicing physicians were all high. Participating in residency training can improve the ability of medical graduates and has a promoting effect on passing the qualifying examination of practicing physicians.

    Background

    Compulsory rural service directed medical student free training program is an important initiative to ameliorate the shortage of health human resources in rural areas of China, and the first graduates of the policy have now completed the contract performance. Analysis of the performance situation and influencing factors of these students is needed to improve the policy of compulsory rural service directed medical student free training program in time and improve and stabilize the performance rate of the rural service directed medical students.

    Objective

    To analyze the employment and performance status of compulsory rural service directed medical graduates of 2015—2019 in four Midwestern medical schools, and to analyze the influencing factors on the performance of the rural service directed medical students, so as to make recommendations to further improve the training policy of the rural service directed medical students.

    Methods

    A cohort of rural service oriented medical students was established from four medical schools including Qinghai University, Guangxi Medical University, Jiujiang college, and Gannan Medical College, and other five-year graduates of clinical medicine from the same session were selected as controls. A baseline questionnaire was administered to graduates before graduation, which included the basic information, family information, job expectations, and so on. An online follow-up survey was conducted annually thereafter and included graduates' employment, performance status, and so on. This study was conducted in July 2021 using data from a baseline survey of graduates of 2015—2019 from four institutions and a follow-up survey from September 2020. A total of 2 041 rural service directed medical graduates and 1 579 other 5-year clinical students were enrolled. Compare the difference in employment between rural service oriented medical graduates and other five-year clinical students. Multivariate Logistic regression was used to analyze the influencing factors on the performance of rural service directed medical graduates.

    Results

    In the baseline survey, 2.26% (46/2 038) of the rural service directed medical graduates were willing to work in township health institutes. In the 2020 follow-up survey, 86.04% (228/265) of the rural service directed medical graduates chose to work in township health institutes. In a 2018 follow-up survey of 2015 and 2016 rural service directed medical graduates, 43.67% (290/664) of graduates expressed reluctance to remain in township health institutes after the expiry of the contract. 97.48% (1 546/1 586) of rural service directed medical graduates were allocated as personnel in public institution, a higher proportion than other clinical 5-year graduates (P<0.05). The overall performance rate of 5-year rural service directed medical graduates was 97.84% (1 589/1 624), and the results of multivariate logistic regression analysis showed that male gender, desired job location as rural areas in the baseline survey, job having public institution quota, and contract location as home district (county) were the promoting factors for the performance of rural service directed medical graduates (P<0.05) .

    Conclusion

    Rural service directed medical students are more smoothly employed with high performance rates, and the recruitment of this type of medical students should focus on students who have willingness to work in rural areas and try to contract with the counties where the students are from.

    Background

    The prevalence of hypertension and cognitive dysfunction in the elderly in China is not optimistic, and hypertension has been associated with an increased risk of developing cognitive dysfunction. It is of great significance to explore and promote the methods for prevention and control of cognitive dysfunction in elderly patients with hypertension in community.

    Objective

    To explore the effect of leisure physical activities on cognitive function in elderly patients with hypertension in community.

    Methods

    From August 2020 to December 2020, a total of 770 patients with hypertension aged ≥65 years who underwent chronic disease management were selected from community health service centers in Wuhan using the stratified random sampling method. A questionnaire was administered to obtain the general information of the subjects, leisure physical activity (including 6 cognitive activities and 11 physical activities) and cognitive function (using the Mini-Mental State Examination Scale). Multivariate Logistic regression was used to analyze the influencing factors of cognitive dysfunction in elderly patients with hypertension. Multiple linear regression was used to analyze the influence of leisure physical activity on cognitive function in elderly patients with hypertension. Multiple Logistic regression was used to analyze the influence of the weekly participation frequency of 17 leisure physical activity on cognitive dysfunction in elderly patients with hypertension.

    Results

    The incidence of cognitive dysfunction in elderly hypertensive patients in community was 39.4% (303/770). There were significant differences in gender, age, education, duration of hypertension, leisure physical activity scores between patients with and without cognitive impairment (P<0.05). Multivariate Logistic regression analysis showed that duration of hypertension〔OR (95%CI) =1.02 (1.01, 1.03) 〕 and leisure physical activity score〔OR (95%CI) =0.98 (0.96, 0.99) 〕 were influencing factors for the development of cognitive impairment in older patients with hypertension. Further analysis found that the leisure physical activity score was an influential factor in the MMSE for scores on the attention and calculation power dimension〔b (95%CI) =0.02 (0.01, 0.03) 〕, the language ability dimension score〔b (95%CI) =0.02 (0.01, 0.03) 〕. After refining the categories to leisure physical activity style, the results of multivariate Logistic regression analysis showed that older adults with hypertension who participated in writing〔OR (95%CI) =0.34 (0.12, 0.95) 〕, board games〔OR (95%CI) =0.21 (0.06, 0.72) 〕 daily were less likely to be cognitively impaired than those who occasionally/never participated in this activity.

    Conclusion

    Leisure physical activity is a protective factor of cognitive function in elderly patients with hypertension, which mainly affects two dimensions of cognitive function: attention and calculating ability, and language ability. Daily participation in writing and checkerboard games play a positive role in cognitive function in elderly patients with hypertension.

    Background

    The needs of outpatient services, a key accessible health resource, are increasing in an increasingly aging population in China. So rational allocation of outpatient service resources to meet older people's health needs is a key to improving their health level.

    Objective

    To explore the factors affecting the utilization of outpatient services in the elderly, to provide feasible suggestions for improving older people's health level and the allocation of medical resources.

    Methods

    This study was conducted in 2021 using the data of older people (≥60 years old) attending the CHARLS 2018. The number of using outpatient services in these people in the past month prior to the CHARLS 2018 and associated factors were studied using a system developed based on the framework of Anderson's Behavioral Model of Health Services Use, with sex, age, marital status, the type of hukou (rural or urban), education level, smoking and drinking were classified as predisposing factors, health insurance, monthly household income per capita and the average distance from home to medical institutions as enabling factors, and chronic disease prevalence and self-rated health as need factors. The zero-inflated negative binomial regression (ZINB) was used to identify factors associated with the use of outpatient services.

    Results

    In all, 9 551 older people were included for analysis. Among them, non-users of outpatient services in the past month numbered 8 038 (84.16%), and one-time, two-time, and three or more-time users numbered 749 (7.84%), 367 (3.84%), and 397 (4.16%), respectively. The number of using outpatient services differed statistically by the type of hukou, education level, smoking, drinking, health insurance prevalence, monthly household income per capita, chronic disease prevalence, and self-rated health status (P<0.05). The results of Logit regression model (one part of the ZINB) in fitting the data indicated that older age, high school education or above, having health insurance, suffering from a chronic disease and poor self-rated health were associated with increased probability of utilizing outpatient services (P<0.05). And the results of negative binomial count model in fitting the data indicated showed that the age of 70-74 years was associated with decreased probability of utilizing outpatient services, while an average distance of greater than 1 km but less than 10 km between home and medical institutions, and three types of self-rated health (good, poor and very poor) were associated with increased probability of utilizing outpatient services (P<0.05) .

    Conclusion

    Our study indicates that the use of outpatient services was insufficient in these older people, which was associated with predisposing, enabling and need factors. To improve this, it is suggested to rationally strengthen the provision of outpatient services to vulnerable groups with underuse of such services and individuals with needs of high-quality services. In addition, attention should be given to chronic disease management and self-rated health of the elderly to improve their awareness and level of health management.

    Background

    Osteosarcopenic obesity syndrome (OSO) is a disease that seriously endangers the health of older people. The rational classification of the disease can guide the clinical diagnosis and treatment. Therefore, classifying OSO based on inter-correlations of its diagnostic variables and exploring its structural properties may offer insights into clinical prevention and treatment of OSO.

    Objective

    To explore the structural properties of OSO, providing a theoretical basis for individualized diagnosis and treatment of the disease.

    Methods

    A cross-sectional study was conducted with a random sample of OSO patients (≥60 years old) who underwent physical examination in Physical Examination Center, the 2nd Affiliated Hospital of Harbin Medical University from January 2018 to December 2020. The data collected include 9 diagnostic variables for OSO〔skeletal muscle index, grip strength, body fat percentage, BMD of the lumbar spine (L1-L4), hip and femoral neck, BMI, waist circumference, walking pace〕, sociodemographic characteristics, lifestyle and prevalence of common chronic diseases. KMO test and Bartlett's test of sphericity were used to evaluate the suitability of diagnostic variables for factor analysis. The components with an eigenvalue equal to or greater than 1.000 were extracted by principal component analysis, and the varimax orthogonal rotation matrix was obtained by the varimax orthogonal rotation method. The common factors were named according to the orthogonal rotation matrix of factors. On the basis of factor analysis, thesum of squares and systematic cluster analysis were used to develop a dendrogram for classifying patients. The structural properties of OSO were analyzed by comparing the values of diagnostic variables and clinical features among patients of different categories.

    Results

    A total of 107 cases were included. The KMO value (0.688) and the result of Bartlett's test of sphericity (χ2=492.374, P<0.001) indicated that the data of diagnostic variables were suitable for factor analysis. Three common factors (osteoporosis factor, muscle + body fat factor and obesity factor) with an eigenvalue greater than 1.000 were extracted, explaining 81.408% variance of the total. The load value of each diagnostic variable on its common factor ranged from 0.770 to 0.918. The patients were divided into 3 categoriesby cluster analysis using the common factors. The skeletal muscle index, grip strength, body fat percentage, BMD of L1-L4, hip and femoral neck, BMI and waist circumference varied significantly across patients of different categories (P<0.05). The values of BMD of L1-L4, hip and femoral neck of OSO patients in the first category were significantly lower than those of the other two categories (P<0.05). The BMI and waist circumference values of OSO patients in the second category were lower than those of the other two categories (P<0.05). OSO patients in the third category had higher values of skeletal muscle index, grip strength and BMD of L1-L4, hip and femoral neck, but lower body fat percentage than those of the other two categories (P<0.05). There were statistically significant differences in sex ratio, distribution of education level and total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), uric acidand creatinine in the serum among different categories of patients (P<0.05). OSO patients in the first category had higher prevalence of below the undergraduate education level than those in the third category (P<0.017). OSO patients in the second category had higher level of TC than those in the third category (P<0.05). In comparison with those in other two categories, OSO patients in the third category had higher personal monthly income equal to or greater than 5 000 yuan, and lower female ratio (P<0.017). Moreover, OSO patients in the third category also demonstrated higher levels of uric acid and creatinine in the serum (P<0.05) .

    Conclusion

    OSO diagnostic variables can be generalized and interpreted in terms of osteoporosis, muscle and body fat, and obesity. And OSO patients have different structural properties. The application of multivariate statistical methods to study the structural properties of OSO patients will contribute to the individualized management of such patients.

    Background

    In the social situation of "three child" policy opening and late marriage to become the norm, the topic of female reproduction and health has attracted increasing attention. As one of the important markers of ovarian reserve in women, the relationship between anti-Mullerian hormone (AMH) and cardiovascular disease and cardiovascular risk indicators has become a hot research issue.

    Objective

    To establish a reference range of AMH in healthy women of reproductive age in Urumqi region, and to investigate the association between AMH and risk factors associated with cardiovascular disease.

    Methods

    From May to July 2018, healthy women aged 19-50 years who met the criteria were selected from the natural population of a community-based epidemiological survey with four living residents area in Urumqi city by targeted sampling, and the serum AMH, fasting plasma glucose, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triacylglyceride (TG), serum uric acid, and thyroid stimulating hormone (TSH) levels of the survey subjects were tested. Height, body mass, abdominal circumference, hip circumference, blood pressure, and other indicators were measured to analyze the relationship between AMH and the above indicators related to cardiovascular risk factors.

    Results

    The median AMH among 855 healthy women of reproductive age was 1.58 (0.01, 8.78) μg/L. The reference range of AMH in healthy women of reproductive age in our region was established, that was, 0.89 to 10.94μg/L for 19-24 years old, 0.66 to 11.77 μg/L for 25-29 years old, 0.27 to 8.25μg/L for 30-34 years old, 0.01 to 6.87μg/L for 35-39 years old, 0.01 to 3.98μg/L for 40-44 years old, <0.01-1.87μg/L for 45-50 years old. Spearman correlation analysis showed that AMH was negatively correlated with age, body fat index (BMI), abdominal circumference, hip circumference, systolic blood pressure, diastolic blood pressure, TSH, TC, LDL-C (P<0.05), but not with blood glucose, TG, HDL-C, uric acid (P>0.05) .

    Conclusion

    In this study, the reference range of serum AMH in healthy women of reproductive age in Urumqi was established, which may provide a basis for the functional assessment of ovarian reserve in women of different ages. Low AMH levels in women of reproductive age are associated with cardiovascular risk factors such as increased age, obesity, abdominal obesity, hypertension, and hyperlipidemia.

    Background

    Female railway workers are a high-risk group for obesity. Information technology is increasingly used in interventions for weight loss in overweight and obese populations. Daily self-weighing is a cognitive-behavioral strategy for self-monitoring of weight, but its effect on weight loss remains still controversial.

    Objective

    To investigate the effect of daily self-weighing plus online group interaction on weight loss and development of healthy lifestyle in overweight and obese female workers in Beijing Railway Bureau.

    Methods

    A prospective randomized controlled study was conducted. Participants were 72 overweight or obese female workers of Beijing Railway Bureau voluntarily recruited from June 1 to September1, 2019. They were equally randomized into an experimental group and a control group, receiving different weight loss interventions for 3 months (intervention scheme for the experimental group: individualized diet and exercise recommendations, daily self-weighing plus online group-based cognitive-behavioral therapy for weight loss, and that for the control group: individualized diet and exercise recommendations, and self-measurement of body weight with weight management counseling during the telephone or hospital follow-up once a month). Baseline and post-intervention data of both groups were collected, including composition indices (body weight, BMI, body fat percentage, fat content, waist circumference, hip circumference, waist-to-hip ratio), blood lipid indices〔total cholesterol (TC), triacylglyceride (TG), high-density liptein cholesterol (HDL-C), low-density liptein cholesterol (LDL-C) 〕and total score and dimension scores of the Health Promoting Lifestyle Profile-Ⅱ (HPLP-Ⅱ). Univariate and multivariate Logistic regression was used to explore factors associated with a 5% or more weight loss from baseline.

    Results

    Seventy-one participants (35 cases and 36 controls) who completed the study were finally included for analysis. The each body composition index, each blood lipid index, and total score and dimension scores of the HPLP-Ⅱ were similar in both groups at baseline (P>0.05). After the intervention, the experimental group showed a significant decrease in the body composition indices (except the waist-to-hip ratio), blood lipid indices (except the HDL-C), and a significant increase in the total score and dimension scores of the HPLP-Ⅱ (P<0.05). However, no significant differences were found in each observation index in the control group before and after the intervention (P>0.05). Compared with the control group, the experimental group showed lower post-intervention body composition indices (except the waist-to-hip ratio) and blood lipid indices (except the HDL-C), and higher post-intervention total score and dimension scores of the HPLP-Ⅱ (P<0.05). A total of 22 participants (31.0%) had a weight loss of ≥5% from the baseline, including 16 cases (72.7%), and 6 controls (27.3%). Both univariate and multivariate Logistic regression analyses showed that intervention scheme and baseline nutrition status were the influencing factors of a 5% or more weight loss from baseline.

    Conclusion

    Daily self-weighing and online group-based cognitive-behavioral interventions contributed to weight loss, formation of a healthy lifestyle, and improvement in quality of life in overweight and obese female workers in Beijing Railway Bureau.

    Background

    In 2019, the National Health Commission issued the Capacity Standards for Community Health Service Center (2018 version), which proposed that the 56 common disease species should be offered diagnosis and treatment services by CHSC, but it did not specify the common disease species of children in the community, which to some extent affects the assessment and construction of CHSC capacity in the community.

    Objective

    To investigate and analyze the common childhood disease species and their characteristics in community health services, in order to provide a reference basis for further community child health service capacity building.

    Methods

    In April 2020, a convenience sampling method was adopted to select community health service agencies in 11 different level cities in China as the sample unit. A self-designed questionnaire was administered to cover the subject's basic condition, the common childhood disease conditions suitable for diagnosis and treatment in the community, and their sequencing. Filled out online voluntarily anonymously by child health service personnel at the sample institution, 3 090 cases were successfully investigated. Respondents ranked the common degree of children's related disorders from low to high, assigning 1 to 5 points to each of the top 5 common childhood disorders, which is, assigning 5 points to ranked 1, 1 point to ranked 5, and 0 points to unselected, calculating a total and sorting by total score.

    Results

    The top 5 disease categories for children in the community were acute upper respiratory infection, diarrhea, bronchitis, pneumonia, and eczema. Of the top 10 ranked community common childhood disorders, 3 were respiratory, 3 were facial and dermatologic, 2 were infectious, and 1 each was a digestive and growth and development related disorder. The top 5 common childhood diseases ranked by different regions, different levels of cities and different posts were consistent, but the ranking order was different, but there were differences in the 6th-10th disease species and order.

    Conclusion

    The current coverage of common childhood diseases in community health services is high. There is regional, urban, and post heterogeneity in common childhood disease species in communities. Construction of community child health service capacity should be oriented to improve the capacity of diagnosis and treatment service of common childhood diseases in the community, and fully consider the disease species variability in different regions, cities, and posts.

    Background

    As the main providers of essential pediatric services, the capabilities of community general practitioners (GPs) in managing pediatric patients may directly reflects the overall status of pediatric care services in primary care settings. In China, there are great regional differences in the supply and demand of pediatric services, and the capabilities of primary care settings are unsatisfactory in providing pediatric services. The current encounters and influencing factors of GPs with pediatric patients in suburban districts are worthy of attention.

    Objective

    To understand the status and associated factors of clinical encounters of GPs with pediatric patients in a suburban district of Beijing, providing a reference for the development of tiered diagnosis and treatment of pediatric diseases.

    Methods

    In June 2021, purposive sampling was used to recruit GPs who participated in a training named "Beijing Miyun District Medical Consortium Construction & General Practitioners' Comprehensive Capability Improvement Project" to attend a semi-structured group interview for understanding the status of clinical encounters of GPs with pediatric patients and related influencing factors. The interview results were recorded, and transcribed, then coded using NVivo 12, and analyzed using thematic analysis.

    Results

    Nineteen GPs (5 men and 14 women) in the age range of 24-51 years〔average age of (33.2±7.6) years〕, attended the interview, 18 of whom had a bachelor degree; 9 had a title of attending physician; 1 had participated in the standardized general practice residency program; 8 had participated in the "3+2" assistant general practitioners training program; 8 had participated in the standardized training before making a career change into general practice. The average years of them working a GP was 1-18 years〔 (6.3±4.8) years on average〕. Four themes emerged from the analysis: (1) Both the numbers of pediatric patients and illnesses encountered by suburban GPs were less than those encountered by their urban counterparts, and pediatric patients encountered by suburban GPs aged greater than or equal to 3 years. (2) Suburban GPs generally had a low level of self-confidence in treating pediatric patients. (3) The major factors negatively affected suburban GPs encountering pediatric patients include the pediatric patient's parents with a lower level of trust in their GP, inadequate capabilities of GPs in managing pediatric patients, high risk of managing pediatric patients, underperformance of nurses, inadequate available pediatric medicines and equipments for laboratory tests in the community, and lack of a clear referral system. (4) The major facilitators for suburban GPs to encounter pediatric patients include managing pediatric patients in the community by pediatricians, and increasing pediatric medicines and equipments for laboratory tests.

    Conclusion

    The encounters of suburban GPs with pediatric patients in primary care were unsatisfactory due to many problems and challenges. To improve the situation, it is suggested to improve the capabilities of suburban GPs in managing pediatric patients by trainings, the collaboration between GPs and pediatricians, and the tiered system for the diagnosis and treatment of pediatric diseases.

    Background

    In China, a rational healthcare seeking pattern in children has not yet taken shape amid the active promotion of the implementation of hierarchical medical system, one major cause of which may be inadequate implementation of first contact in primary care settings in children due to poor service capability for children of these institutions. Therefore, it is of great practical significance and application value to analyze the influencing factors of children's intention to seek healthcare in primary healthcare institutions.

    Objective

    To investigate children's intention to seek healthcare in primary healthcare settings and associated determinants, offering insights into the development of a sound and rational healthcare-seeking pattern in children.

    Methods

    Two surveys were conducted during March to July, 2021 using a questionnaire developed based on the Anderson's Behavioral Model of Health Services Use (containing three aspects: demographics of children and their guardians, children's opinions on hospital selection for treatment and associated factors, and intention to seek healthcare in primary care. One survey was offline, with children aged 0-14 years as participants accidental sampled from people in two grade A tertiary general hospitals, three community health centers, and other public places (such as public parks and squares) in Guangzhou's urban areas, and the other one was online, with a purposive sample of age-matched children included in a WeChat group as participants. For collecting information more appropriately, the questionnaire was completed by the children's guardians. Univariate and multivariate ordinal regression were used to identify factors associated with children's intention to seek healthcare in primary care.

    Results

    Altogether, the results of questionnaires effectively answered by the guardians of 501 children were used for analysis. The prevalence of intending to seek healthcare in primary care in the children was 36.53% (183/501). The prevalence of primarily choosing a primary healthcare setting for initial treatment of common diseases was 26.3% (132/501), which were mainly owing to shorter distance between home and the hospital (83.3%, 110/132), shorter waiting time for treatment (40.9%, 54/132) and having a pediatric or general practice clinic (36.4%, 48/132). Multivariate Logistic regression analysis indicated that the level of intention to seek healthcare in primary care in children was increased if the nearest hospital was a primary hospital instead of a secondary or tertiary hospital〔OR (95%CI) =1.514 (1.060, 2.166) 〕. Visiting a primary hospital at least four times in the last year was associated with a higher level of intention to seek healthcare in primary care in children compared with visiting a primary hospital zero times〔OR (95%CI) =0.248 (0.111, 0.557) 〕. A higher level of intention to seek healthcare in primary care in children was associated with parents' high level of satisfaction with primary care services instead of parents' fair level of satisfaction with primary care services〔OR (95%CI) =0.348 (0.236, 0.515) ] or parents' dissatisfaction with primary care services〔OR (95%CI) =0.086 (0.043, 0.173) 〕.

    Conclusion

    In general, the children in Guangzhou mainly seek healthcare in nearby hospitals, and the their level of intention to seek healthcare in a primary hospital could be improved greatly. To improve their satisfaction with primary care services and intention to seek healthcare in primary care settings, it is suggested to further deepen the theoretical research and practical exploration regarding hierarchical diagnosis and treatment, strengthen the cooperation between primary and higher level hospitals for balancing the distribution of pediatric medical resources among hospitals, and to improve the pediatric service capabilities of primary hospitals via improving the software and hardware configuration of these hospitals.

    Background

    For building a healthy China, it is essential to expand the coverage of family doctor services. In young and middle-aged office building occupants, the rate of contracting family doctor services is low. Shanghai has taken the lead in exploring building-based family doctor services, and providing on-demand health management services. So it is particularly meaningful to study the health needs in young and middle-aged office building occupants.

    Objective

    To investigate the needs and associated factors of contracted family doctor services among young and middle-aged office building occupants in Shanghai.

    Methods

    A questionnaire survey was conducted from December 2019 to December 2020 with a cluster random sample of young and middle-aged office building occupants (aged 18-59 years) selected from representative office buildings in Shanghai's Hongkou District, Pudong New District, and Jing'an District of Shanghai for understanding their sociodemographic characteristics, health and healthcare-seeking conditions, knowledge of family doctor services, and needs of essential and personalized family doctor services. Multiple Logistic regression analysis was used to analyze the factors affecting the needs of family doctor services.

    Results

    In all, 2 366 cases attended the survey, and 2 272 of them (96.03%) who completed the survey effectively were included for analysis. Among them, 87.65% (1 874/2 138) had general, moderate or strong needs for essential family doctor services, and 70.59% (1 452/2 057) had needs for personalized family doctor services. Multiple Logistic regression analysis indicated that age, education level, self-assessed social class, understanding of one's own health, self-assessed health status, chronic disease prevalence, mental health status, preferred healthcare setting for treating common diseases, treatment experience in a community health institution, understanding of and degree of trust in a family doctor, and understanding of building-based family doctor services and the specific scope of the services were associated with the needs of essential family doctor services (P<0.05). Education level, social health insurance, commonly used drugs, chronic disease prevalence, preferred healthcare setting for treating common diseases, treatment experience in a community health institution, understanding of building-based family doctor services, and understanding of the scope of building-based family doctor services were associated with the needs of personalized family doctor services (P<0.05) .

    Conclusion

    The contracted family doctor services were in high demand in young and middle-aged office building occupants. Improving health literacy in this population, modifying publicity strategies regarding the services, and improving the capabilities of the family doctor team and primary medical institutions, may be conducive to increasing the rate of contracting family doctor services in this group.

    Background

    Shanghai is gradually expanding the supply of family doctor contract service to building functional communities, but the prevalence of met needs of such services in young and middle-aged office building occupants is still unknown, and relevant studies on the prevalence and associated factors could inform the development and improvement of policies regarding building-based family doctor services.

    Objective

    To explore the prevalence of met needs for contracted family doctor services and associated factors in young and middle-aged office building occupants.

    Methods

    A questionnaire survey was implemented from December 2019 to December 2020 in the setting of office buildings selected by typical sampling from Hongkou District, Pudong New District and Jing'an District of Shanghai. Among the young and middle-aged occupants (n=2 272, 18-59 years old) selected from the buildings by use of cluster random sampling to attend the survey, 1 137 with an experience of using contracted family doctor services were determined as the participants. The survey involved four aspects, including sociodemographic and economic characteristics, health status, understanding level of contracted family doctor services, and met needs of these services (containing essential and personalized service needs assessed using a 5-point Likert scale). Multinomial and ordinal Logistic regression was used to analyze factors associated with met needs of contracted family doctor services.

    Results

    The prevalence of having needs of essential family doctor services considerably/completely met was 39.61% (425/1 073). And that of having needs of personalized family doctor services considerably/completely met was 39.01% (419/1 074). Multinomial and ordinal Logistic regression analysis revealed that registered place of household (Shanghai or not), occupation, annual income, self-rated health, understanding of the "1+1+1" type of contracted family doctor services, level of trust in family doctors, and evaluation of family doctors' service capabilities were associated with met needs of essential family doctor services (P<0.05). Sex, annual income, chronic disease prevalence, understanding of the "1+1+1" type of contracted family doctor services and the composition of a family doctor team, as well as evaluation of family doctors' service capabilities were associated with met needs of personalized family doctor services (P<0.05) .

    Conclusion

    The prevalence of self-reported met needs of essential or personalized family doctor services in the young and middle-aged office building occupants was about 40%, which was associated with sociodemographic and economic characteristics, health status, understanding level of contracted family doctor services, and self-assessed family doctors' service capabilities. It is recommended to improve the publicity of the system of contracting family doctor services, customize personalized service plans according to the characteristics and differentiated needs of the population, improve the family doctor's service capabilities and enrich the services.

    Background

    The prevalence of sub-health problems is increasing in young and middle-aged office building occupants, in which the percentage of mental health problems is on the rise. Shanghai took the lead in delivering family doctor services via the health station set in an office building in June 2018, but mental health in young and middle-aged people has not yet been insufficiently covered by the services.

    Objective

    To assess the prevalence of anxiety and influencing factors in young and middle-aged office building occupants in Shanghai.

    Methods

    A questionnaire survey for estimating anxiety prevalence was carried out in typically sampled office buildings from Hongkou District, Pudong New District and Jing'an District of Shanghai during December 2019 to December 2020. Cluster random sampling was used to sample young and middle-aged occupants (18-59 years old) in the buildings, and 2 198 cases of them who completed the survey were included as the participants for analysis. Anxiety was diagnosed by the score of the Zung's Self-Rating Anxiety Scale. Multiple linear regression was used to estimate the association of anxiety prevalence with socio-demographic and economic characteristics, and health status as well as lifestyle.

    Results

    Among the participants, the prevalence of no anxiety, mild, moderate and severe anxiety was 60.42% (1 328/2 198), 18.61% (409/2 198), 12.46% (274/2 198), and 8.51% (187/2 198), respectively. Multiple linear regression analysis found that registered place of household (Shanghai or not), education level, self-rated social class, self-rated health, frequency of physical examination, level of fatigue, chronic disease prevalence and regular medication were associated with anxiety prevalence (P<0.05) .

    Conclusion

    The prevalence of anxiety was high in this group of population, which may be associated with the population characteristics. In view of this, mental health should be valued during the delivery of family doctor services for these people, and targeted interventions can be provided according to personal anxiety status when necessary.

    Background

    The Effectiveness Satisfaction Questionnaire for COPD (ESQ-COPD) previously developed by us based on classical test theory has proven to have some limitations. The combination use of classical test theory and item response theory may achieve complementary advantages, which may be a theoretical basis and methodological support for the development or revision of instruments.

    Objective

    To develop a modified ESQ-COPD (mESQ-COPD) based on the combination of disease and syndrome, and to evaluate its psychometric properties.

    Methods

    By predefining basic characteristics of the instrument, normalizing the essential concepts and terminologies, revising the conceptual framework, generating an item pool, and reviewing the items, the draft of the mESQ-COPD was developed by our revision group. Then the draft was improved to be a mESQ-COPD by screening items based on the results of a pretest conducted during October 2017 to February 2018 with a convenience sample of 265 stable COPD patients from the respiratory clinic of 10 grade A tertiary hospitals in China, in combination with item screening using the classical test theory and item response theory. After that, the psychometric properties of the mESQ-COPD were tested using an onsite investigation carried out in a convenience sample of 365 stable COPD patients from the respiratory clinic of six grade A tertiary hospitals in China from November 2018 to February 2019.

    Results

    The final mESQ-COPD includes four domains (clinical symptoms, capabilities for work and life, ability of environmental adaptation, and therapeutic effect) and 19 items. The Cronbach's α of the questionnaire was 0.949, and that of the four domains was 0.943, 0.869, 0.829, and 0.767, respectively. The correlation coefficient between the domain of clinical symptoms, capabilities for work and life, ability of environmental adaptation, or therapeutic effect and its component items ranged from 0.667 to 0.798, 0.855 to 0.882, 0.795 to 0.907, or 0.857 to 0.934, respectively. Confirmatory factor analysis showed that the comparative fit index, incremental fit index, non-normed fit index, standardized root mean square residual, and root mean square error of approximation measuring the construct validity of the mESQ-COPD were 0.94, 0.94, 0.93, 0.07, and 0.16, respectively. The correlation coefficients of the mESQ-COPD and its domains with COPD assessment test ranged from 0.371 to 0.538, while those of the mESQ-COPD and its domains with the modified Medical Research Council scale ranged from 0.329 to 0.564. The differences in the total score and domain scores of the mESQ-COPD between mild/moderate and severe/extremely severe COPD patients were both statistically significant (P<0.01). The acceptance rate of the mESQ-COPD was 99.5%, and the completion rate was 99.2%, with a mean completion time of (6.13±4.59) min.

    Conclusion

    The 19-item mESQ-COPD (consists of four domains: clinical symptoms, ability of work and life, capability for environmental adaptation, and therapeutic effect) has good reliability, validity, and applicability, which could be used to support the efficacy evaluation in COPD.

    Background

    Palliative care improves the quality of life of patients with cancer. The development and utilization of palliative care needs screening tools can help health care providers rapidly, accurately, and scientifically identify cancer patients with palliative care needs and enable health care providers to provide them with palliative care related services in a more timely manner. Currently, the literature on screening tools for palliative care needs in China is less common.

    Objective

    To hance the palliative care needs screening tool (PCST) and test its validity in hospitalized cancer patients.

    Methods

    The PCST was bidirectionally translated following the Brislin translational model. Cultural commissioning of the Chinese version of PCST through expert panel meetings and pre survey. A total of 173 cancer patients admitted to the Department of oncology, biotherapeutics, interventional, and integrative medicine of the Third Affiliated Hospital of Navy Military Medical University were selected for the study from December 2020 to May 2021 using convenience sampling, and the general information questionnaire, Chinese version of PCST were used for this investigation. The critical ratio method and correlation of the item-total scores were used for item analysis, and the content validity of the scale was assessed by expert scoring. To evaluate the validity of known-groups, the palliative care needs screening results of patients with different characteristics were compared. Cronbach's α Coefficient and Guttman compromise coefficient were used to evaluate the internal consistency of the scale. Pearson correlation was used to evaluate the inter rater reliability and test-retest reliability of the scale.

    Results

    The Chinese version of the PCST includes 10 items, with scores ranging from 0 to 14 points. The CR values of entries ranged from 0.621 to 8.820, and all entries except entries 1 and 8 achieved significant values (P<0.05). The correlation coefficients between the scores of the individual entries and the total score of the scale ranged from 0.161 to 0.795 (P<0.05), and all entries except entries 8 achieved values greater than 0.200. The mean content validity index was 0. 943 at the scale level, and ranged from 0.429 to 1.000 at the entry level. Cronbach's α for the scale was 0.612, and the Guttman halving coefficient was 0.538. The inter rater reliability coefficient was 0.967 (P<0.001) and the test-retest reliability coefficient was 0.960 (P<0.001). Taking a score of 5 as the cutoff for palliative care needs screening, 35.3% (61/173) of the 173 inpatient cancer patients who completed screening required palliative care support. The needs for palliative care in hospitalized cancer patients varied significantly across patients by age groups, number of children, length of illness, number of cancer symptoms, number of visits for cancer in past 6 months, nutritional status and self-care ability (P<0.05) .

    Conclusion

    The Chinese version of PCST has good reliability, simplicity and understanding, and it can be used to screen and evaluate the need for palliative care in hospitalized cancer patients in China.

    Currently, increasing prevalence of noncommunicable diseases (NCDs), poor patient compliance, and scarcity of personalised diagnosis and treatment are still the primary challenges for the prevention and control of NCDs in China. The arrival of era of big data provides supports for establishing new models to unblock the bottlenecks and solve the prominent problems in NCDs containment. We briefly introduced the concept and characteristics of big data, outlined its importance in the prevention and control of NCDs, and analysed current applications of big data technique-based models in containing NCDs as well as the achievements in the construction of platforms for NCDs risk prediction and containment using big data techniques. After that, we reviewed the advantages and limitations of the above-mentioned NCDs risk prediction models and platforms for NCDs risk prediction and containment, then put forward recommendations for strengthening the explanatory power of the models and optimising the development of the platforms. All of these are for further development of intelligent containment of NCDs.

    Family doctor studio is a new concept derived from the general practice clinic in primary care institutions, which is a platform and carrier used by a general practice team to serve the contracted residents. However, the research on family doctor studios in China is still in the initial exploratory stage. A scientific and rational service quality assessment system is urgently needed to be developed for family doctor studios with the increasing prevalence of the concept of integration of medical and preventive care, and the demand for improving the quality of health services. In view of this, we introduced the SPO (structure-process-outcome) model in detail, and reviewed the studies about quality assessment systems for the structure, process and outcome of primary care services, providing a theoretical basis for further standardizing the construction of family doctor studios in Sichuan province.
