Objective To investigate the antibiotic resistance of extended-spectrum β-lactamases (ESBLs)-producing bacteria,and the risk factors for patients with hospital-acquired lower respiratory tract infections caused by these bacteria.Methods The clinical data of 80 cases of hospital-acquired lower respiratory tract infections caused by ESBLs + bacteria in the People's Hospital of Qingtian in Zhejiang Province from July 2008 to December 2011 were collected; and 160 cases of nosocomial infection caused by ESBLs- bacteria were randomly selected as controls.Univariate analysis and multivariate logistic regression were used to analyze the risk factors for ESBLs + bacteria infection.The resistance of sixteen antibiotics was detected by K-B method.Results Univariate analysis revealed that the risk factors for nosocomial lower respirator tract infection caused by ESBLs+ bacteria were hospitalization ≥ 10 d,readmission to hospital,oxygen inhalation,invasive operations,using antacid ＞ 7 d,using glucocorticoids ＞ 7 d,using immunosuppressant ＞ 7 d,using third-generation cephalosporins,using fluoroquinolone antibacterials,and the combined use of antibiotics≥3 d.Multivariate logistic regression analysis identified five independent risk faetors:oxygen inhalation (OR =8.613,95％ CI:1.870-39.659),invasive operations (OR =5.900,95％CI:1.885-18.467),using third-generation cephalosporins (OR =7.465,95％ CI:2.364-23.578),using fluoroquinolone antibacterials (OR =4.481,95％ CI:1.197-16.781) and combined use of antibiotics≥3 d (OR =5.346,95％ CI:1.717-16.643).ESBLs + Escherichia coli and Klebsiella pneumoniae strains were sensitive to imipenem,meropenem,cefoperazone /sulbactam and piperacillin/tazobactam (with the resistance rates lower than 30.00％),but were highly resistant to most β-lactam,aminoglycoside,fluoroquinolone and sulfonamide antibacterials.Conclusion ESBLs + isolates were highly resistant to most antibacterials,and hospital-acquired lower respiratory tract infections with ESBLs+ bacteria are mainly related with invasive operations and the use of antibiotics.

Objective To study the pulmonary functions of pediatric ALI/ARDS(acute lung injury/acute respiratory distress syndrome) survivors. Method A prospective cohort study of all survivors of ALI/ARDS in the PICU of Beijing Children's Hospital was performed. Patients were divided into three groups(0-3 years of age,3 ～ 7 years of age, and over 7 years of age) and followed up three months after diagnosis. Results There were 36 survivors in total of 44 ALl patients, three patients lost follow-up, 12 died and 21 survived. Five survivors refused to participate in the study because of asymptomatic, and one was unable to participate because of lymphoma com-bined with sepsis. A total of 15 children completed the whole survey (11 patients were less than 3 years old, andfour were over 7 years of age). Twelve patients had no discomfort in their respiratory tracts. Three months after be-ing enrolled, the pulmonary functions of all children improved, especially in terms of tidal volume and respiratory compliance (P<0.05). Conclusions The abnormal respiratory symptoms and signs in most children disap-peared three months after discharge. Most survivors still have pulmonary dysfunction at 3 monthes after discharge, but better than discharge.

Objective:To analyze the staff salary status and the influencing factors in traditional Chinese medicine(TCM) hospitals implementing the salary system reform in Sichuan province in 2020, for reference in optimizing the salary system reform of such hospitals.Methods:Cluster sampling and institutional survey were used to collect the salary information of 26 TCM hospitals in 21 cities(prefectures)of Sichuan province implementing the salary system reform in 2020. Such information was then subject to descriptive analysis, while the influencing factors of salary were subject to one-way analysis of variance and generalized linear model multifactor analysis.Results:15 428 staff from 26 TCM hospitals were included as the research objects. In 2020, personnel expenditure accounted for 40.23% of the total expenditure, and 24.34% of which came from financial subsidy in 26 TCM hospitals. The average annual payable income per person was(149 312±74 288)yuan, 67.82% of which being performance pay. Analysis of variance showed that there were significant differences among the salary levels of staff in different economic regions, hospital grades, hospital levels, gender, educational background, position, seniority, performance pay ratio, employment in the government system and other natures, senior and other professional titles, doctors and other positions( P<0.05), and the differences were still statistically significant after adjustment by generalized linear model( P<0.05). Conclusions:The reform of the salary system of Sichuan TCM Hospitals has basically achieved equal pay for equal work, and the income of low-level personnel has been improved. However, the salary level was not very motivated and the salary structure was not guaranteed. It is necessary to strengthen financial precision subsidies, increase the proportion of personnel expenditure, so as to support the increase of the absolute value of salary in non-core economic areas, improve the salary structure, reasonably widen the salary gap among different educational backgrounds and positions, further optimize internal distribution, and ensure the sustainable development of Chinese medicine talents.

Objective:To analyze the salary characteristics of medical institutions and the influencing factors of personnel expenditure as found in the salary system reform of public hospitals in Sichuan province, for reference in furthering such reform in public hospitals.Methods:The data of personnel expenditure, business operation and medical services came from 96 medical institutions in 21 cities(prefectures)of Sichuan province from 2017 to 2020 by means of institutional survey. The average salary level and salary structure of medical staff were used to describe the salary characteristics, and the total salary was presented by the level of personnel expenditure. The measurement data was represented by M(IQR), the counting data was described by frequency and constituent ratio, and the influencing factors of personnel expenditure were analyzed by generalized linear mixed model. Results:From 2017 to 2020, the personnel expenditure of medical institutions increased by 13.04% annually. In 2020, the per capita salary level of medical staff was 151 900 yuan, while the basic salary and performance salary accounted for 16.20% and 54.60% of personnel expenditure respectively. The analysis results of the generalized linear mixed model showed that the average cost of patients per visit( β=0.596), the level of drugs and sanitary materials consumed per 100 yuan medical income( β=0.286), the number of medical visits( β=0.328), and the years [(2018, 2019, 2020) β=0.025, 0.052, 0.066] were positively correlated to personnel expenditure, while the average length of stay( β=-0.693), the proportion of medical service income( β=-0.392), and the balance rate of income and expenditure( β=-0.062)were negatively correlated to personnel expenditure( P<0.05). The proportion of fiscal subsidy revenue, regional GDP and asset-liability ratio were not the influencing factors of personnel expenditure( P> 0.05). Conclusions:In the reform of the salary system of the province, its salary level of medical institutions has surpassed the current wage ceiling of these institutions. As the salary distribution was mainly made based on the workload, the " baton" role of the salary system reform has begun to pay off. However, the basic guarantee role of compensation has not yet been fully leveraged.Further reform is needed in upgrading refined management, and timely dynamic adjustment of personnel expenditure in combination with the hospital's financial performance and cost analysis, and reasonably optimizing the level of medical staff compensation.

Objective:To analyze the experiences and practice in the reform of public hospital salary system in Sichuan province, summarize the typical modes of such reform in the province, and provide references for further reform.Methods:As of October 29, 2021, the research group received 77 sets of typical experience materials submitted by the health commissions and public hospitals in Sichuan province on enforcing the reform of the public hospital salary system. The analysis framework was based on the five main elements proposed in the Guidance to Deepening the Reform of the Salary System of Public Hospitals for the purpose of furthering the reform. These five elements refer to " reasonably determining the level of salary in public hospitals" " fully implementing the autonomy of internal distribution in public hospitals " " establishing and improving the incentive and restraint mechanism for the remuneration of public hospital leaders" " improving the assessment and evaluation mechanism oriented to public welfare" and " funding sources ". A quantitative analysis was made on the typical experience materials using the social network analysis method, while a qualitative analysis was made on the typical experience materials using the content analysis method. Results:The results of social network analysis showed that the network density was 0.272; the highest point centrality was " fully implement the autonomy of internal distribution in public hospitals" (0.935), and the highest intermediary centrality was " improving the assessment and evaluation mechanism oriented to public welfare" (0.870), while the closeness to centrality of " establishing and improving the incentive and constraint mechanism for the salary of public hospital leaders" (0.434) and " funding sources" (0.421) were relatively low. The results of content analysis showed that the ones with higher frequency among all the typical experience materials were " fully implementing the autonomy of internal distribution of hospitals" (72 times) and " improving the assessment and evaluation mechanism oriented to public welfare" (67 times), while the ones with lower frequency were " establishing and improving the salary incentive and constraint mechanism for public hospital leaders" (17 times) and " funding sources" (14 times). In terms of unity and synergy, the typical models of public hospital salary system reform in the province could be categorized as the fine standard mode, the fair value mode, the autonomous synergy mode and the circular symbiosis mode.Conclusions:Deepening the reform of the salary system of public hospitals should unify the standards and improve the fair and refined assessment and evaluation mechanism; explore various forms of distribution and build an internal autonomous and synergistic incentive mechanism; pay attention to the weak remuneration incentive mechanism for hospital leaders and the problem of a relatively single source of funding.
