Objective To investigate and analyze the difficulties of nosocomial infection management in different-level medical institutions in Shanghai, and to provide scientific basis for improving the level of nosocomial infection management. Methods A questionnaire was designed to include 10 difficulties in nosocomial infection management such as professional title promotion, salary, and personnel allocation. In October 2023, the Shanghai Nosocomial Infection Quality Control Center, in collaboration with the Shanghai Hospital Association, conducted a questionnaire survey among the heads of nosocomial infection management departments in medical institutions in Shanghai. The scores of difficulties were analyzed by stratification according to hospital level, allocation and changes of full-time personnel. Results A total of 548 questionnaires were distributed, and 530 valid questionnaires were retrieved, with a recovery rate of 96.72%. There were 55 public tertiary, 93 public secondary, 169 public primary and 213 social medical institutions. The rates of full-time personnel allocation meeting standards were 76.36% (42/55), 72.04% (67/93), 31.95% (54/169), and 21.60% (46/213), respectively. There was a statistically significant difference in the rates of full-time personnel allocation meeting standards among different levels of medical institutions (χ2=105.149, P<0.001). There was no statistical difference in the total scores of nosocomial infection management difficulties among different-level medical institutions (F=1.657, P=0.176). There were statistically significant differences in the scores of difficulties in professional title promotion, cumbersome daily norms and requirements, insufficient allocation of full-time personnel, and high personnel turnover (P<0.05). Conclusions The main difficulties in nosocomial management of medical institutions at all levels in Shanghai include the difficulty in career promotion, cumbersome daily norms and requirements, insufficient allocation of full-time personnel and lack of experience. In the future, medical institutions should strengthen the allocation of full-time personnel and enhance their capabilities, provide smooth promotion channels, to promote the high-quality development of nosocomial infection management ultimately.
Objective To evaluate the effect of ECRS management model on the quality of prevention and control of hospital infection with multidrug-resistant organisms (MDROs). Methods The data related to the prevention and control of MDROs in the First Hospital of Nanchang in 2020 and 2021 were retrospectively collected. The hospital implemented routine MDRO infection prevention and control management in accordance with the Expert Consensus on the Prevention and Control of Multi-drug Resistant Bacteria Nosocomial Infection in 2020. On this basis, the hospital applied the four principles of the ECRS method to cancel, combine, rearrange and simplify the MDRO infection prevention and control management. The detection rate of MDROs on object surfaces, the incidence rate of hospital infection of MDROs, the compliance rate of hand hygiene, the implementation rate of contact isolation prevention and control measures, and the pass rate of MDRO infection prevention and control education assessment were analyzed and compared between the two years. Results The detection rate of MDROs on the surfaces in 2021 was lower than that in 2020 (9.39% vs. 31.63%). The hospital-acquired MDRO infection rate in 2021 was lower than that in 2020 (1.18% vs. 1.46%). The hand hygiene compliance rates of medical staff, workers and caregivers in 2021 were higher than those in 2020 (90.99% vs. 78.63%, 73.51% vs. 45.96%, 70.96% vs. 33.71%). The implementation rate of contact isolation prevention and control measures in 2021 was higher than that in 2020 (93.31% vs. 70.79%). The qualified rates of MDRO infection prevention and control education in medical personnel, workers and caregivers in 2021 were higher than those in 2020 (96.57% vs. 81.31%, 76.47% vs. 47.95%, 73.17% vs. 34.19%). All the differences above were statistically significant (P<0.05). Conclusion ECRS management mode can improve the execution and prevention level of MDRO hospital infection prevention and control, and reduce the incidence of MDRO hospital infection.
Objective To explore the key contents of nosocomial infection prevention and control training for medical staff in secondary and above hospitals, so as to provide scientific basis for training in the future. Methods The medical workers who participated in the training of nosocomial infection prevention and control in secondary and above hospitals of 6 prefecture-level cities in Jiangxi province in December 2020 were selected. The same questionnaire was used to test the participants before and after training, and the changes of scores before and after training were compared. Results A total of 73 medical workers were included. After training, the total scores of the questionnaire (14.13±1.95 vs. 11.27±2.76; t=11.053, P<0.001), scores of manual hygiene specifications knowledge unit (4.63±0.65 vs. 4.02±1.37; t=4.215, P<0.001), scores of hospital isolation technical specifications knowledge unit (4.28±1.05 vs. 3.47±1.29; t=4.895, P<0.001), scores of airborne disease hospital infection prevention and control norms knowledge unit (5.21±0.96 vs. 3.76±1.04; t=10.419, P<0.001) and the overall accuracy of the questionnaire (83.00% vs. 66.32%) were higher than those before training. Conclusions After the training, the accuracies of different topics are improved, but there is still room for improvement in each knowledge unit. More effective training strategies should be considered.
ObjectivesTo understand the current situation of the nosocomial infection management system in maternal and child health care institutions at all levels in Sichuan province, and provide a feasible policy basis for strengthening the nosocomial infection management.MethodsThe expert group members of Sichuan Maternal and Child Health Association Academy Association designed a unified questionnaire, and distributed the questionnaire through “Questionnaire Star” to carry out on-site online survey.ResultsA total of 159 maternal and child health care institutions participated in the survey. Most secondary and below maternal and child health care institutions had not set up professional hospital infection monitoring system. A few secondary and below maternal and child health care institutions did not independently set up a hospital infection management committee, hospital infection management department, full-time hospital infection department head, the inspection team of infection control, monitoring system, and nosocomial infection management system and special supervision had not been established in special departments. There were statistical differences in some jobs in the construction of nosocomial infection management system in different levels of maternal and child health care institutions (P<0.05).ConclusionsThe organizational system construction of hospital infection managemen are at a low level in the second level and below maternal and child health care institutions in Sichuan province. The tertiary maternal and child health care institutions should give full play to the leading role in promoting the standard construction of nosocomial infection management system of maternal and child health care institutions in Sichuan province, and carry out nosocomial infection management of maternal and child health care institutions orderly.
Objective To understand the current rate of nosocomial infection and its changing trend in a grade A comprehensive hospital in 10 years, and to provide scientific basis for the monitoring, control and management of nosocomial infection. Methods Using the method of cross-sectional survey, the inpatients in Mianyang Central Hospital from 2011 to 2020 were selected for bedside survey, and the questionnaire was filled in after review of medical records. The data of cross-sectional survey of nosocomial infection were collected, and the infection-related data of nosocomial and community-acquired infection of patients in each department were statistically analyzed. Results A total of 19 595 cases were investigated. The prevalence rate of nosocomial infection was 3.79%, and the the case prevalence rate of nosocomial infection was 4.04%. The prevalence of community-acquired infection was 33.44%, and the case prevalence rate of community-acquired infection was 35.30%. The departments with higher prevalence rate in nosocomial infection were intensive care unit, neurosurgery, cardiothoracic surgery and hematology. The departments with high prevalence rate in the community-acquired infection were burn department, pediatrics department, neonatology department, respiratory medicine department and pediatric intensive care unit. The most common site of nosocomial infection was lower respiratory tract infection, followed by upper respiratory tract sensation, urinary tract, abdominal tissue and blood. The main pathogens of nosocomial infections were Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, and Pseudomonas aeruginosa. The utilization rate of antibacterial drugs was 42.93%. There was a downward trend in prophylactic drug use, mainly one drug combination, and the proportion of combination drug decreased.Conclusion Through the investigation, it can be seen that the key points of nosocomial infection management and prevention and control should be lower respiratory tract infection, postoperative surgical infection, multi-drug resistant bacteria management and rational use of antibiotics.
When a clustered coronavirus disease 2019 epidemic occurs, how to prevent and control hospital infection is a challenge faced by each medical institution. Under the normalization situation, building an effective prevention and control system is the premise and foundation for medical institutions to effectively prevent and control infection when dealing with clustered epidemics. According to the principles of control theory, medical institutions should quickly switch to an emergency state, and effectively deal with the external and internal infection risks brought by clustered epidemics by strengthening source control measures, engineering control measures, management control measures and personal protection measures. This article summarizes the experience of handling clustered outbreaks in medical institutions in the prevention and control of coronavirus disease 2019, and aims to provide a reference for medical institutions to take effective prevention and control measures when dealing with clustered outbreaks.
Objective To describe the current state of hospital infection prevention and control for flexible endoscope in Shanghai, and analyze the trend of infection prevention and control quality from 2018 to 2022. Methods According to Regulation for Cleaning and Disinfection Technique of Flexible Endoscope (WS 507－2016), the quality of infection prevention and control for flexible endoscope was divided into seven parts: organizational management, layout, cleaning and disinfection (sterilization) process, environmental disinfection and sterilization, final rinse water, recording and monitoring, and occupational protection. Each quality control item was judged according to the on-site score and the correction opinion, and the item with correction opinion was judged as “unqualified”, otherwise it was “qualified”. The results of the infection prevention and control quality supervision for flexible endoscope from 2018 to 2022 were reviewed and analyzed, and the qualification rates of quality control items for hospitals at different levels and in different years were calculated. Results From 2018 to 2022, the total qualification rates of organization management, final rinse water, environmental disinfection and sterilization, and occupational protection were over 90%, and the total qualification rates of cleaning and disinfection (sterilization) process, and records and monitoring were over 80%. There was no statistically significant difference in the annual qualification rate (P>0.05). The total qualification rate of the layout was 78.19%, which was significantly higher before the outbreak of COVID-19 (2018-2019) than after the outbreak of COVID-19 (2020-2022) (P<0.001). There was no significant difference in the qualification rate of different levels of hospitals in terms of organizational management, layout, cleaning and disinfection (sterilization) process, records and monitoring, or occupational protection item (P>0.05). There were statistical differences in the qualification rates of different levels of hospitals in terms of final rinse water and environmental disinfection and sterilization (P<0.05). Conclusions The infection prevention and control qualification rate of flexible endoscope in Shanghai is high. However, the layout qualification rate after the COVID-19 pandemic is lower than before. There has been no significant trend in the quality of other items in the past five years. Weaknesses in the cleaning and disinfection (sterilization) process, as well as in recording and monitoring, are identified as key areas in management. Targeted training and supervision are recommended to address these weaknesses.
ObjectiveTo summarize the clinical experience in the prevention and treatment of novel coronavirus (2019-nCoV, SARS-CoV-2) disease (COVID-19) in the department of thoracic surgery of large grade A tertiary hospitals in Wuhan, and to provide feasible clinical practice strategies.MethodsThe clinical data of 41 COVID-19 patients in the department of thoracic surgery of 7 large grade A tertiary hospitals in Wuhan from December 15, 2019 to February 15, 2020 were analyzed retrospectively. There were 20 surgical patients (10 males and 10 females at an average age of 54.35±10.80 years) and 21 medical personnel (7 males and 14 females at an average age of 30.38±6.23 years).ResultsThe main clinical manifestations of COVID-19 patients were fever (70.73%) and cough (53.66%). Normal or reduced peripheral white blood cells and reduced lymphocyte counts were found in the COVID-19 patients, and some patients may have increased C-reactive protein. COVID-19 patients showed limited ground-glass opacities in early chest CT, which was evident in the edge band of lung. The disease could further develop into multiple pulmonary infiltrations, and pulmonary consolidation was found in severe cases. At the time of confirmed diagnosis, most of the medical personnel were ground-glass shadows and unilateral lesions, and even no obvious abnormalities were found in the lungs. The diagnosed COVID-19 patients were transferred to the isolation ward immediately and treated according to the "Diagnosis and Treatment Program of Novel Coronavirus Pneumonia", which was released by the National Health Commission of the People's Republic of China. At the end of follow-up on February 20, 2020, seven surgical patients (35.00%) were discharged and seven (35.00%) were dead, 13 (61.90%) medical personnel were discharged and no death was found.ConclusionsOf all COVID-19 patients in the department of thoracic surgery of hospitals in Wuhan, the proportion of severe degree and mortality in surgical patients are significantly higher than that of the general population, and medical personnel are prone to nosocomial infections. Early oxygen therapy and respiratory support may improve prognosis. During the epidemic period of COVID-19, elective or limited surgery is suggested to be postponed and the indications for emergency operation should be strictly controlled. Emergency operation is suggested to be treated in accordance with tertiary prevention. On the consideration of specialty in the department of thoracic surgery, all people of the ward should be carefully investigated for infection once one case is confirmed with COVID-19. Early detection, isolation, diagnosis, and treatment are the best preventive measures to improve the prognosis of COVID-19.
Objective To investigate a suspected outbreak of hospital-acquired infections caused by Mycobacterium chelonae related to flexible bronchoscope (hereinafter referred to as “bronchofibroscope”) and apply targeted high-throughput sequencing (tNGS) technology for etiological analysis, providing references for controlling hospital infection outbreaks. Methods A retrospective survey of patients who were detected with Mycobacterium chelonae through tNGS testing of bronchoalveolar lavage fluid (BALF) after bronchofibroscopy at the Zhengdong District, People’s Hospital of Henan University of Chinese Medicine, People’s Hospital of Zhengzhou between May 1, 2018 and March 18, 2024. The causes were investigated through comprehensive measures including on-site epidemiological surveys and environmental health assessments, and intervention measures were developed and evaluated for effectiveness. Results A total of 52 patients were included. Mycobacterium chelonae was detected in 30 patients, nosocomial infection was excluded in all cases. The suspicious contaminated bronchofibroscope lavage fluid and its cleaning and disinfection equipment, environment and other samples were collected. The traditional microbial culture results were negative. The tNGS results showed that Mycobacterium chelonae was detected in bronchofibroscope lavage fluid (sequence number 156), and all the patients with Mycobacterium chelonae detected in BALF used the bronchofibroscope. It was judged that this event was a pseudo-outbreak of nosocomial infection caused by the contamination of bronchofibroscope with the patient’s BALF. After three months of continuous follow-up after the comprehensive control measures were taken, Mycobacterium chelonae was not detected by tNGS in bronchofibroscope lavage fluid or patients’ BALF. All patients in the hospital improved and discharged without any new cases. The pseudo-outbreak of nosocomial infection was effectively controlled. Conclusions There are many links in the reprocessing of bronchofibroscope, which is easy to cause pollution, and the management needs to be strengthened. tNGS detection has the characteristics of high efficiency, few background bacteria and clear pathogen spectrum, which can be used as a supplementary means for the investigation of nosocomial infection outbreaks, and is of great significance for identifying the source of infection and determining the transmission route.
Objective To preliminarily understand the equipment configuration and information system function improvement of the microbiology laboratory for etiological submission before antibiotic treatment in Chinese medical institutions, and provide a scientific basis for further targeted action work on the rate of etiological submission before antibiotic treatment. Methods A network questionnaire was released in “Sentinel Hospital Information Reporting System of National Hospital Infection Management Professional Quality Control Center” between March 1 and June 21, 2022. The second-level and above hospitals were investigated. Results A total of 783 hospitals were included, of which 765 (97.7%) hospitals had been equipped with microbiology laboratory equipment to varying degrees, and the allocation rate of tertiary hospitals was higher than that of secondary hospitals (P<0.05). The top three items of common pathogenic test were aerobic (98.3%), bacterial smear (97.6%) and fungal smear (95.1%), and the last three items were streptococcus pneumoniae urine antigen (20.4%), silver hexamine staining (19.0%) and gene sequencing (8.9%). The comparison of relevant information system and function improvement among hospitals of different levels showed that tertiary hospitals were superior to secondary hospitals (P<0.05). In different regions, except for the allocation rate of nosocomial infection information monitoring system and rational drug use monitoring system (P>0.05), other relevant systems and functional improvement of hospitals in eastern, central and western regions, the differences were statistically significant (P<0.05). The number of hospitals that could obtain the indicators of “etiological submission rate of inpatients before antibiotic treatment”“etiological submission rate related to hospital infection diagnosis”“etiological submission rate before combined use of key drugs” were 698 (89.1%), 474 (60.5%) and 337 (43.0%), respectively. Among the factors affecting the implementation of special actions, 454 hospitals (58.0%) thought that the information system was not fully functional, 341 hospitals (43.6%) thought that the etiology testing project was not fully carried out, and 148 hospitals (18.9%) thought that the microbiology laboratory testing ability was insufficient. Conclusion All kinds of hospitals at all levels in China, especially specialized and secondary hospitals, need to further improve the configuration of equipment and information system functions in the microorganism laboratory related to aetiology inspection, strengthen the support for microbial inspection, and strengthen information management, monitoring and analysis.
