ObjectiveTo sum up experiences of precaution and provide evidence to prevent such accidents in the future via analyzing the nosocomial infection in newborn babies who were infected by rotavirus. MethodsWe investigated and monitored the 8 cases of nosocomial infection occurred between July 7th and July 14th, 2012 by epidemiologic and environmental hygienic methods, and analyzed the existing risk factors and took measures to control. ResultsThere were 8 nosocomial infected cases among the 45 newborn babies who were hospitalized. The infection rate was 17.8% and the accident lasted for 7 days. The distribution of space, time and population was clustered. Environment and hands were the main media to spread the virus. ConclusionThe accident was a suspected nosocomial infection caused by rotavirus in the hospital. It can be controlled effectively through intensive cleaning and sterilizing, isolated touching, and improving the medical staff's compliance and accuracy rate of hand sanitation.
ObjectiveTo explore the risk factors for multiple nosocomial infection in adult hospitalized patients, so as to provide references for the control of nosocomial infection. MethodsThe clinical data of adults hospitalized patients with nosocomial infection in the Second Affiliated Hospital of Fujian Medical University during Jan. 2015 to Dec. 2015 were collected, and the susceptible factors of multiple nosocomial infections referencing to the single nosocomial infection were analyzed. Results1226 cases (1368 case-times) of nosocomial infection were found and the infection rate and the case-time infection rate were 2.24% and 2.49%, respectively. Single factor analysis results showed that the top four risk factors of multiple nosocomial infection included hospital stay ≥30 days (25.5%), first infection time ≥30 days (23.2%), incision type Ⅲ (16.7%), and surgery (13.4%). Logistic regression analysis result showed, after adjusting the influence of age and gender, longer hospital stay was the independent risk factor of multiple nosocomial infection referencing to single nosocomial infection (OR=3.475, 95%CI 2.545 to 4.745). ConclusionLonger hospital stay is the independent risk factor of multiple nosocomial infection of adult hospitalized patients. Measures should be taken to shorten the length of stay in hospital and reduce the exposure to the high-risk environment, so as to reduce the incidence of multiple nosocomial infection.
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.
ObjectiveTo optimize procedures of going out for examination for patients with multidrug-resistant organism, strengthen prevention and control management of nosocomial infection, and prevent nosocomial infection.MethodsPatients with multidrug-resistant organism who went out for examination were selected from April to November 2018. April to July 2018 (before implementation) was process construction stage, and August to November 2018 (after implementation) was process optimization implementation stage. In April 2018, process and management system of going out for multidrug-resistant organism patients were formulated, training of transporters was strengthened, and measures such as checklist identification, accompany patients for examination, patient handover, isolation and protection, and disinfection of materials were implemented, to realize the infection prevention and control management in the whole process of going out for multidrug-resistant organism patients. We compared relevant indicators before and after implementation.ResultsA total of 262 cases times of patients with multidrug-resistant organism were included, including 134 cases times before implementation and 128 cases times after implementation. Compared with before implementation, the hand hygiene, wearing gloves, disinfection of inspection instruments and articles, patient transfer, isolation measures in waiting process (special elevator, isolation after waiting for inspection, arrange inspection time reasonably), education and training after implementation improved(P<0.05). Before and after implementation, the Methicillin resistant staphylococcus aureus detection rate difference was statistically significant (P<0.05).ConclusionsThe optimization of procedures of examination for patients with multidrug-resistant organism can increase implementation rate of indirect indicators such as hand hygiene, disinfection of inspection instruments and articles, isolation and protection, education and training in the prevention and control of multidrug-resistant organism in nosocomial infection. And it is important for the prevention and control of multi-disciplinary collaboration of multidrug-resistant organism.
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 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.
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 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.
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.
