Objective:To survey the knowledge levels of chronic obstructive pulmonary disease(COPD) among physicians in primary care and related factors.Methods:A questionnaire survey was conducted during December 2020 to December 2021 among 1 232 primary care doctors in Zhumadian City of Henan Province. The questionnaire included basic information, knowledge of COPD and its management, and the training received. The COPD-related knowledge levels and the influencing factors were analyzed using logistic regression model.Results:A total of 1 232 questionnaires were collected, and 1 221(99.1%) were valid, which were included in the analysis. The survey showed that the COPD-related knowledge level was significantly associated with the educational level of primary care physicians(χ2=9.91, P<0.05); and the Pearson correlation analysis showed that the knowledge level was positively correlated with educational level( r=0.09, P<0.05). In terms of risk factors, causes of acute exacerbations, and treatment and management of COPD, there was a linear relationship between the education level and knowledge level(χ2=13.86, P<0.001;χ2=20.93, P<0.001); the Pearson correlation analysis showed that the knowledge level was correlated with higher educational level( r=0.11, P<0.001; r=0.13, P<0.001). In terms of symptoms and diagnosis, there was no correlation between educational level and awareness level(χ2=1.90, P=0.168). Logistic regression model showed that compared to doctors aged 20-30, those aged 31-40 had a higher COPD-related knowledge level( OR=2.24, 95% CI: 1.16-4.30, P=0.016); compare to the doctors with associate degree, doctors with bachelor degree or above had a higher COPD-related knowledge( OR=1.71, 95% CI:1.24-2.37, P=0.001); compared to doctors without professional title, those with primary or middle-rank professional title had a higher knowledge level( OR=1.65, 95% CI: 1.28-2.13, P<0.001; OR=2.15, 95% CI: 1.46-3.16, P<0.001); compared to doctors with training time<3, those with training time ≥3 had a higher knowledge level( OR=1.15, 95% CI: 1.21-2.61, P=0.021). Conclusion:The COPD-related knowledge levels(especially in knowledge of risk factors and causes of acute exacerbations, and treatment and management of COPD) among doctors in primary care are affected by age, educational background, professional title, and the number of training sessions.

Objective:To discuss the development and management of full-time research assistants in China′s large hospitals.Methods:Through the methods of policy sorting, literature research, summarization, and classification, this study focused on the policy background, development opportunities, and the needs of the times for the position establishment of research assistants in China′s large hospitals, comprehensively classified the practical exploration and existing problems of employing and managing full-time research assistants in typical large hospitals in the country, and discussed the relevant management strategies learned from international experience.Results:In addition to hospitals directly affiliated with colleges and universities, dozens of large local hospitals in more than ten provinces have carried out beneficial practices of establishing the employment, management, and assessment systems for research assistants positions and achieved some progress. However, there are still common problems such as limited cognition of ″temporary positions″, insufficient coverage of the positions, low salary and welfare, and lack of training and development mechanisms as well as promotion and career development paths.Conclusions:The development and management of research assistants in large hospitals have gradually shifted their purpose from alleviating the employment issue of the graduates to reserving talented people in medical teaching, researching and managing, forming a high-quality, professional, and full-time medical scientific team, and continuously innovating. This article puts forward some suggestions about establishing the management system of research assistants, strengthening the standardized training for talented people, and constructing a diversified incentive mechanism combining performance appraisal and target management for research assistants.

Respiratory disease is currently one of the main causes of human deaths. Due to the shortage, fragmentation, imbalance and heterogeneity of health resources and medical resources in China, it is urgent to strengthen the prevention and control system and capacity construction for respiratory science and innovate the prevention and treatment mode.The authors expounded the necessity of constructing a medical alliance for respiratory diseases, and held that such an alliance can achieve the purpose of patient care and discipline development, by means of integration of resources and system building, from such aspects as healthcare, teaching, research and department construction.

Objective:To summarize the achievements in standardized development of pulmonary and critical care medicine discipline, for references of developing respiratory discipline at secondary and tertiary hospitals.Methods:Questionnaire survey was used to understand the input and technical promotion of the secondary and tertiary medical institutions in the standardized construction.Results:The secondary and tertiary medical institutions invested 1.116 billion yuan to carry out standardized development of the discipline, recruiting 1 164 doctors, 2 535 nurses and 334 technicians. In terms of key medical technologies, 58 tertiary medical institutions and 45 secondary medical institutions meet the basic standards of " guidance on medical service capacity of respiratory discipline(2018 edition)" after carrying out standardized development.Conclusions:The discipline of pulmonary and critical care medicine should continue to strengthen its input in the development of respiratory and critical medical integration, with standardized development projects as the breakthrough. Evaluation should be carried out persistently so as to promote the development, for the purpose of improving the prevention and treatment capability of pulmonary and critical care medicine.

Objective:To analyze the screening status of high-risk population of chronic obstructive pulmonary disease (COPD) in areas where “Happy Breathing” project was carried out.Method:There were 1 008 518 COPD screening questionnaires (COPD-SQ) filled out in 18 pilot areas of “Happy Breathing” program from November 2017 to October 2019. Within subjects who scored 16 points or more with COPD-SQ, 63 523 of them underwent pulmonary function tests before bronchodilator inhalation. Stratified analysis, chi-square test and other statistical methods were performed to analyze the distribution of COPD high-risk groups, the prevalence of COPD among high-risk groups and risk factors of COPD.Results:Results in this study suggested that the high-risk population of COPD accounted for 18.99% (191 498/1 008 518) of the population who received the questionnaire screening. Among the high-risk population who received lung function test, 31.59% (20 070/63 523) were screened and diagnosed as COPD patients. As for risk factors of COPD, the proportion of high-risk population was higher in people with a smoking index ≥600 compared with never-smokers (54.20% vs 12.60%), and the prevalence of COPD was also higher in people with a smoking index ≥600 (35.62% vs 25.22%); people who were exposed to second-hand smoke almost every day also showed an increased proportion of high-risk groups (27.39% vs 10.97%) and a high prevalence of COPD (31.36% vs 27.93%) than those without second-hand smoke exposure; the presence or absence of biofuel exposure also caused the difference in the proportion of high-risk groups (33.92% vs 13.11%); compared with people without a family history of respiratory diseases, the proportion of high-risk groups (56.38% vs 16.42%) and the prevalence of COPD in high-risk groups (32.40% vs 29.19%) were both higher in those with family history of respiratory diseases.Conclusion:The high-risk group of COPD accounts for a high proportion of the screened population, suggesting that the “Happy Breathing” project is feasible and necessary in COPD screening, which is helpful for the development of COPD diagnosis and treatment.
