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.
ObjectiveTo identify the risk factors of Intensive Care Unit (ICU) nosocomial infection in ICU ward in a first-class hospital in Wuxi, and discuss the effective control measures, in order to provide evidence for making strategies in preventing and controlling nosocomial infection. MethodsAccording to the principle of random sampling and with the use of case-control study, a sample of 100 nosocomial infection patients were selected randomly from January 2012 to December 2014 as survey group, and another 100 patients without nosocomial infection as control group. The data were input using EpiData 2.0, and SPSS 13.0 was used for statistical analysis; t-test and χ2 test were conducted, and the risk factors were analyzed using multi-variate logistic regression model. The significant level of P-value was 0.05. ResultsBased on the results of univariate analysis, there were 13 risk factors for ICU nosocomial infection, including diabetes mellitus, hypoproteinemia, being bedridden, surgical operation, immunosuppression, glucocorticoids, organ transplantation, tracheal intubation, length of hospitalization, length of mechanical ventilation, length of central venous catheter, length of urinary catheter, and length of nasogastric tube indwelling. Multi-variate logistic analysis indicated that hospitalization of 7 days or longer[OR=1.106, 95%CI (1.025, 1.096), P=0.001], diabetes mellitus[OR=2.770, 95%CI (1.068, 7.186), P=0.036], surgical operation[OR=7.524, 95%CI (2.352, 24.063), P=0.001], mechanical ventilation of 7 days or longer[OR=1.222, 95%CI (1.116, 1.339), P<0.001], and nasogastric tube indwelling of 7 days or longer[OR=1.110, 95%CI (1.035, 1.190), P=0.003] were considered as independent risk factors for ICU nosocomial infection. ConclusionHospitalization of 7 days or longer, diabetes mellitus, surgical operation, tracheal intubation of 7 days or longer, and gastric intubation of 7 days or longer are the major risk factors for nosocomial infection in ICU ward. Advanced intervention and comprehensive prevention measures are helpful to reduce the nosocomial infection rate and ensure the safety of medical treatment.
Since the establishment in 2016, especially after the outbreak of coronavirus disease 2019 (COVID-19) epidemic, the Hospital Infection Management Quality Control Center of Shuangliu District has carried out quality management and technical ability training for full-time and part-time infection prevention and control personnel through various methods, and used grid management to organize examinations and assessments, inspections and supervision, as well as consultation and assistance. As a result, the culture of infection prevention and control has been deeply rooted in the hearts of the people, the health administrative departments have increased investment in infrastructure and equipment, the funds for infection prevention and control have continued to increase, and the prevention and control quality of COVID-19 and daily works in the region has been continuously improved. The center plays a leading role in the promotion of the standardization, homogenization, and quality improvement of the prevention and control of hospital infection in the district.
The article summarized the national and international history and current situation of healthcare-associated infection control, and analyzed the tendency of new technique and progress in healthcare-associated infection control according to the experience in research and practice.
Objective To understand the current situation of nosocomial infection management quality control centers at the municipal and county levels in Guizhou, so as to provide measures for promoting the construction of nosocomial infections management quality control centers at all levels in Guizhou. Methods From September 26th to October 12th 2023, based on the mobile network platform survey questionnaire of the infection prevention and control workshop, a survey was conducted on the establishment, personnel, information technology level, management, and quality control work of the nosocomial infection management quality control centers at the municipal and county levels in Guizhou. Results Nine prefecture-level cities/autonomous prefectures in Guizhou had established municipal-level nosocomial infection management quality control centers. The professional background of the staff at the municipal and county-level quality control centers was mainly nursing (accounting for 36.4% and 58.4%, respectively), and their educational background was mainly undergraduate (accounting for 70.5% and 83.3%, respectively). No quality control center at the municipal or county level had established an information-based quality control platform for nosocomial infection management within the region. Most county-level quality control centers did not have special funds (87.5%), and there were still 16 (25.0%) county-level quality control centers that had not established relevant systems for work and management. The main forms of quality control work carried out by each center were organizing training, on-site inspections, guidance and evaluation, and most of them were conducted irregularly. Conclusions Guizhou has basically formed a quality control system for nosocomial infection management at the provincial, municipal, and county levels. However, the nosocomial infection management quality control network has not fully covered all districts, and policies, funding support, and personnel allocation are still insufficient. Health administrative departments and quality control centers at all levels need to unify monitoring standards and quality control norms, strengthen supervision, improve quality control capabilities, and improve training systems to achieve standardization and normalization of quality control work throughout the province and improve quality control efficiency.
Objective To explore the application of risk assessment of nosocomial infection control in outpatient departments, so as to find out the high-risk departments and high-risk links of nosocomial infection, and to provide basis for the formulation of nosocomial infection prevention and control measures in outpatient departments. Methods The improved risk assessment tool was used to evaluate the nosocomial infection management risk in the outpatient departments of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology. We evaluated risk indicators and risk levels from three dimensions: likelihood of risk occurrence, severity of consequences, and integrity of the current system. Results Among the evaluated outpatient departments, the departments with extremely high risk levels included pediatric fever outpatient department (147.8 points), pediatric outpatient department (141.2 points), emergency internal medicine department (139.4 points), and pediatric emergency department (138.8 points). The departments with high risk levels included internal medicine outpatient department (138.4 points), dermatology outpatient department (136.0 points), otolaryngology-head and neck surgery outpatient department (135.6 points), and ophthalmology outpatient department (134.0 points). The risk assessment scores of 31 outpatient departments showed a normal distribution. The evaluation results of various risk indicators showed that among the 26 risk indicators, there were 2 extremely low risk, 4 low risk, 6 medium low risk, 7 medium high risk, 4 high risk, and 3 extremely high risk. The 3 extremely high risk indicators were lack of nosocomial infection prevention and control knowledge, patients with difficult to identify diseases (air/droplet transmission) seeking medical treatment, and crowded waiting areas for patients. Conclusions The comprehensive risk assessment of outpatient departments can screen out high risk outpatient departments and find out the main risk links. We can concentrate resources on key departments, prevent key risks, and improve the efficiency of nosocomial infection control.

ObjectiveTo analyze the trend of hospital infection, so as to provide a scientific basis for hospital infection prevention and control. MethodsFrom 2011 to 2013, according to the criteria of diagnosis of nosocomial infections set up by the Ministry of Health, the prevalence rates of nosocomial infections in patients who were hospitalized on the survey day were investigated by the combination of bedside investigation and medical records checking. ResultsThe incidence rates of nosocomial infections from 2011 to 2013 were 2.99%, 2.31% and 1.95%, respectively, presenting a downward trend. The rate of hospital infection was the highest in comprehensive Intensive Care Unit, and the main infection site was the lower respiratory tract. Gram-negative bacteria were the main pathogens causing hospital infections, including Klebliella pnermoniae, Pseudomonas aeruginosa, Staphylococcus aureus, Acinetobacter baumannii and Escherichia coli. The utilization rates of antibacterial agents in these three years were respectively 39.84%, 34.58% and 34.22%. ConclusionTargeted surveillance and management of key departments and sites should be strengthened. It is necessary to strengthen the surveillance and management of antibiotics, raise the submission rate of pathogens, and use antibiotics appropriately.
ObjectiveTo find out the major isolates distribution, drug resistance changes of multidrug-resistant organisms (MDRO) in 2013 for rational use of antibiotics and hospital infection control. MethodsA total of 32 566 cultured bacteria samples from the patients diagnosed between January 1st and December 31st 2013 were collected, using conventional tube biochemical assays and semi-automatic automicrobic (AMS) for bacteria identification; and antimicrobial susceptibility testing, major drug resistance mechanism detection were performed according to CLSI documents. MDRO definition was made according to the 2011 international consensus from European Center for Disease Control and Prevention (CDC), American CDC, Clinical and Laboratory Standards Institute (CLSI), and Food and Drug Administration. The data was analyzed by WHOnet 5.6 software. ResultsWe got 3 684 strains isolates, G- accounted for 76.08%, G+ 16.80%, fungi 7.11%, and fastidious bacteria 17.29%. The top ten isolates in order were:E.coli, A.baumannii, Ps.aeruginosa, H.influenzae, K.pneumoniae, S.aureus, S.pneumoniae, A.fumigatus, M.catarrhalis and C.freundii. From the first quarter 2012 to the fourth quarter 2013, the extended spectrum β lactamases (ESBL)-producing E.coli increased from 40.23% to 53.54%, ESBL-producing K.pneumonia increased from 14.28% to 34.78%, XDR-A.baumannii increased from 62.38% to 99.25%, metalloenzyme-producing Ps.aeruginosa increased from 7.37% to 25.37%, methicillin resistant staphylococcus aureus increased from 23.81% to 58.70%, and VRE increased from 0.00% to 28.12%. ConclusionIn the isolates, the percentage of G- was the highest, and the rate of MDRO are all unremittingly raising, which suggests us should pay more attention to microbiology analysis, rational use of antibiotics, strengthening hospital infection control, reducing the bacterial resistance, and strengthening MDRO surveillance.
ObjectiveTo investigate the prevalence of nosocomial infection in a hospital and to provide a basis for hospital infection control. MethodsUsing bedside investigation and medical records analysis, we surveyed all hospitalized patients from 00:00 to 24:00 on July 19th, 2013. ResultsThe real investigation was carried out on 1815 patients out of all the 1828 patients with a real investigation rate of 99.29%. There were 55 cases of nosocomial infection (55 case-times), and both the nosocomial point infection rate and case-time infection rate were 3.03%. The top three departments with the highest rate were Intensive Care Unit (37.50%), Neurosurgery Department One (13.73%) and Neurosurgery Department Two (12.00%). Most infections occurred on the lower respiratory tract, which accounted for 45.45%. Nosocomial infection pathogenic detection rate was 38.18% (21/55):6 cases of Staphylococcus aureus (28.57%), 5 of Pseudomonas aeruginosa (23.81%), 3 of Klebsiella pneumoniae (14.29%), and 2 cases of Acinetobacter baumanii (9.52%). The rate of antimicrobial drug use was 24.08%, in which drug treatment accounted for 75.29%. Gender, surgery, urinary catheter, vascular catheter, tracheostomy, ventilator application, hemodialysis, and use of antibiotics were all influencial factors for occurrence of nosocomial infection. ConclusionNosocomial infection prevalence survey can help fully understand the status of hospital infection, help to carry out targeted surveillance, and better guidance for hospital to prevent and control nosocomial infection.
