ObjectiveTo compare the clinical characteristics of patients with nosocomial and community infections with extended-spectrum beta-lactamase-containing Klebsiella pneumoniae (ESBL-KP) and non-ESBL-KP so as to improve clinical diagnosis and treatment outcomes.MethodsThis retrospective study determined the clinical features of patients with nosocomial and community infections with KP who were admitted to our hospital from January 1st, 2017 to June 30th, 2018. The chi-square test or Fisher's exact probability method were used to compare different groups.ResultsWe identified 334 strains of KP, and 83 (24.9%) of them strains were EBSL-KP. The percentages of ESBL-KP infections among those with nosocomial and community infections were similar (31.25% vs. 22.27%, χ2=2.955, P=0.086). Significantly more females than males had ESBL-KP infections (32.32 vs. 21.70%, χ2=4.208, P=0.040). The percentages of ESBL-KP infections were similar among <18 years-old group, 18 to 45 years-old group, 45 to 60 years-old group, and ≥60 years-old group. The three major locations of KP infections were the lower respiratory tract, urinary tract, and bloodstream (bacteremia). Among nosocomial KP infections, there were no significant differences in the percentages of ESBL-KP infections at different sites, nor in the hospital departments where patients were treated; among community KP infections, there were significant differences in the percentages of ESBLs-KP infections at different sites, and in the hospital departments where patients were treated. For community KP infections, the two most common infection sites were the urinary tract (37.74%) and the skin and soft tissue (30.77%), and most patients were treated in the urology department (40.00%) and respiratory medicine department (38.10%). ESBL-KP isolates had greater resistance than non-EBSL-KP isolates to 16 tested antibiotics (P<0.05). There were no statistically significant differences in the percentages of nosocomial infections and community infections among those with ESBL-KP and among those with non-ESBL-KP (P>0.05).ConclusionsOur population have high rates of nosocomial and community KP infections and of infections with ESBL-KP. It is necessary to strengthen the management and clinical use of antibiotics and to provide real-time surveillance of KP infections, especially for patients with ESBL-KP infections. Increased vigilance is required for KP infections of females and community KP infections to improve control of nosocomial infections and reduce the prevalence of cross-infections.
ObjectiveTo explore the distribution of multidrug resistant organism in neonates admitted to the hospital through various ways, and analyze the risk factors in order to avoid cross infection of multidrug resistant organism in neonatology department. MethodsA total of 2 124 neonates were monitored from January 2012 to July 2013, among which 1 119 were admitted from outpatient department (outpatient group), 782 were transferred from other departments (other department group), and 223 were from other hospitals (other hospital group). We analyzed their hospital stays, weight, average length of stay, and drug-resistant strains, and their relationship with nosocomial infection. ResultsAmong the 105 drug-resistant strains, there were 57 from the outpatient group, 27 from the other department group, and 21 from the other hospital group. The positive rate in the patients transferred from other hospitals was the highest (9.42%). Neonates with the hospital stay of more than 14 days and weighing 1 500 g or less were the high-risk groups of drug-resistant strains in nosocomial infection. Drug-resistant strains of nosocomial infection detected in the patients admitted through different ways were basically identical. ConclusionWe should strengthen screening, isolation, prevention and control work in the outpatient neonate. At the same time, we can't ignore the prevention and control of the infection in neonates from other departments or hospitals, especially the prevention and control work in neonates with the hospital stay of more than 14 days and weighing 1 500 g or less to reduce the occurrence of multiple drug-resistant strains cross infection.
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 investigate the prevalence rate of nosocomial infection in West China Hospital of Sichuan University and to analyze the implementation effect of nosocomial infection control measures, so as to provide reference for infection control.MethodsAn investigation of the prevalence rate of nosocomial infections was performed on patients who were admitted in West China Hospital of Sichuan University from 0:00-24:00 on a day of every late June from 2012 to 2018 by using bedside investigation in combination with inpatient medical record query, and the data was verified, summarized, and statistically analyzed by the professionals of Nosocomial Infection Management Department.ResultsFrom 2012 to 2018, the prevalence rates of nosocomial infections were 5.19%, 4.20%, 3.94%, 4.26%, 4.29%, 4.25%, and 2.97% in West China Hospital of Sichuan University, which tended to decline (χ2=32.826, P<0.001). There was no significant difference in annual total infection rate in the Department of Internal Medicine, however, the infection rate in the Department of Hematology tended to decline (χ2=6.127, P<0.05); in the Department of Surgical Medicine, the total infection rate tended to decline(χ2=18.721, P<0.001); in particular, the infection rate in the Department of Thoracic Surgery tended to decline(χ2=3.906, P<0.05); the annual difference in infection rate in the Intensive Care Unit (ICU) was not statistically significant. The key site of nosocomial infection was dominated by the lower respiratory tract, and the annual difference was not statistically significant. In particular, postoperative pneumonia has increased since 2014 (χ2=9.56, P=0.002). The nosocomial pathogens which had the highest constituent ratio over the years were Acinetobacter baumannii (in 2012, 2013, 2014, 2017, and 2018), Klebsiella pneumonia (in 2015), and Escherichia coli (in 2016). The annual difference in rate of antimicrobial use was not statistically significant(χ2=3.75, P=0.053), while the rate of antimicrobial use in the ICU tended to decline (χ2=30.42, P=0.000).ConclusionsThe prevalence rate of nosocomial infection in West China Hospital of Sichuan University tends to decline. However, sufficient attention still requires to be paid to lower respiratory tract infection, particularly for patients with postoperative pneumonia.
ObjectiveTo investigate the educational background of practitioners from the hospital infection control departments located in the mainland of China and reveal the necessity and employment prospects of setting up a major of hospital infection control for a bachelor degree in universities.MethodsA self-designed questionnaire was used to conduct an online survey on the Shanghai International Forum for Infection Control and Prevention and the WeChat group of nosocomial infection control from March 12th to March 25th, 2018. The convenient sampling method was used to investigate the leader of infection prevention and control department in each hospital. The survey included the regional distribution, attention on nosocomial infection control, existing staff structure, future staff needs and employment prospects of hospitals in 2018, and the attention on nosocomial infection control in the same period in 2014.ResultsA total of 1 654 questionnaires were obtained, from 30 provincial-level regions, including 103 maternal and child health hospitals, 143 other special hospitals, 258 hospitals of traditional Chinese medicine, and 1 150 general hospitals. Hospitals upgraded more attention on nosocomial infection control in 2018 than in 2014 [(3.76±0.98) vs. (2.94±1.14) points; t=-36.112, P<0.001]. Currently, there were 5 068.5 labors engaged in nosocomial infection control. The educational background of the current practitioners was mainly nursing [60.52% (3 067.5)]. In the next 5 years, 83.50% (820/982) of the hospitals that had recruitment plans planed to recruit graduates specialized in the hospital infection control, and respectively, 44.86% (742/1 654) and 17.35% (287/1 654) of the respondents believed that the employment prospects of graduates with bachelor degree specialized in the hospital infection control were good or very good.ConclusionThere is a tremendous demand for the graduates specialized in the hospital infection control, and it is imperative to set up this undergraduate major.
ObjectiveTo explore the risk factors for neonatal nosocomial infection and the pathogen resistance, in order to provide the basis for hospital infection control. MethodsSurveillance of hospital infection in newborns hospitalized for more than 48 hours were carried out from January to December 2012, and the risk factors for hospital infection were analyzed. ResultsThere were 54 newborn cases with neonatal nosocomial infection, and the infection rate of newborns was 1.25%. The major infection sites were respiratory tract (66.7%), gastrointestinal tract (18.5%), skin and soft tissues (9.2%). Birth weight (χ2Trend=126.88, P<0.001), hospitalization days (χ2Trend=106.89, P<0.001), invasive operation (χ2=5.338, P=0.021) were the major risk factors. A total of 54 strains of pathogenic bacteria were isolated from 54 newborn cases with neonatal nosocomial infection. Twenty-three strains of gram-positive bacteria accounted for 42.6%, which were generally resistant to penicillin and large ring lactone class antibiotic drugs. Thirty-one strains of gram-negative bacteria accounted for 57.4%, which were mainly resistant to the three generations of cephalosporins. ConclusionThe hospital infection rate of newborns is low. Birth weight, hospitalization days and invasive operation are the major risk factors for neonatal nosocomial infection.
ObjectiveTo explore the effect of case-based learning combined with scenario exercise on nosocomial infection prevention and control training.MethodsClinical nursing students who entered the Department of Western & Traditional Chinese Medicine between September 2018 and November 2019 were selected. These students entered in groups. According to the entry number, the groups were divided into trial group and control group by odd or even numbers. The two groups of nursing students were trained by the infection prevention and control nursing group of the department to prevent nosocomial infection on the first day of entering the department. The trial group adopted case-based learning combined with scenario exercise, while the control group adopted traditional lecture-based learning. The two groups were compared by hand hygiene compliance rate, hand hygiene accuracy rate, clinical waste classification and disposal accuracy rate, occupational exposure, nosocomial infection prevention and control assessment scores, and teaching method satisfaction.ResultsA total of 63 nursing students from 10 groups were enrolled. There were 32 students from 5 groups in the control group and 31 students from 5 groups in the trial group. The hand hygiene compliance rate (χ2=8.434, P=0.004), clinical waste classification and disposal accuracy rate (χ2=4.196, P=0.041), nosocomial infection prevention and control assessment scores (t=3.145, P=0.003) and satisfaction scores of teaching methods (t=2.446, P=0.017) in the trial group were all higher than those in the control group. There was no occupational exposure in the trial group, but 1 case in the control group. The correct hand hygiene rates of the two groups were both 100%.ConclusionCase-based learning combined with scenario exercise can effectively improve the awareness of nosocomial infection prevention and control, improve the knowledge and skills of nosocomial infection prevention and control, improve the effectiveness of nosocomial infection prevention and control training, and increase the satisfaction of clinical teaching.
ObjectiveTo understand the current status of nosocomial infections in a municipal medical unit, to find problems in daily monitoring, and to provide the evidence for the prevention and control of nosocomial infection in high-risk groups and procedures. MethodsAccording to the 2013 survey requirements made by the nosocomial infection control center of Chengdu, we made a cross-sectional survey about nosocomial infection among all the inpatients on July 25th, 2013 and statistically analyzed the results. ResultsTotally, 1 301 cases were actually investigated within 1 307 inpatients of the time (the actual investigation rate was 99.54%). The prevalence rate of nosocomial infection was 3.38% (44 cases). The top five departments of infection rate were Respiratory Intensive Care Unit (RICU), Center of Intensive Care Unit (CICU), Department of Neurosurgery, Department of Thoracic Surgery and Department of General Surgery. The main site of infection was respiratory tract, which took possession of 62.25%. In univariate analyses, age≥60, length of hospital stay >2 weeks, invasive operation, history of diabetes, operation, radiotherapy/chemotherapy, utilization of antibiotics were found to be risk factors for infections. Multivariate analysis showed that length of hospital stay (OR=3.115, P=0.001), invasive operation (OR=14.930, P<0.001), diabetes mellitus (OR=2.157, P=0.046), radiotherapy/chemotherapy (OR=7.497, P<0.001) were independent risk factors for nosocomial infections. The utilization rate of antibiotics was 45.73%. Among them, there was 85.21% using single antibiotics, and 82.18% of them were used therapeutically. ConclusionUnderstanding the current status of nosocomial infection in municipal hospitals helps us grasp the key and difficulty of infection control, make out prevention-control measures for high-risk groups and high-risk departments, and guide and supervise its implementation in clinical departments, which points out the direction to further reduce the incidence of nosocomial infection.
ObjectiveTo enhance the management of occupational exposure, improve post-exposure reporting, promote post-exposure follow-up, reduce blood-borne infections caused by exposure, and ensure occupational safety among medical staff by using comprehensive measures based on nosocomial infection management system.MethodsAll the reported cases of occupational exposure were retrospectively collected from August 2012 to July 2018. The cases were divided into the control group (from August 2012 to July 2015) in which the data were reported in paper, and the observation group (from August 2015 to July 2018) in which the data were reported by nosocomial infection management system. The report and follow up results of occupational exposure in the two groups were compared and analyzed.ResultsAfter three years application of nosocomial infection management system, the occupational exposure report increased 95.8% (increased from 16.7 cases per year to 32.7 cases per year); the follow-up ratio of occupational exposure after one month,3 months and 6 months increased from 65.0% to 93.3% (χ2=15.184, P<0.001), 45.0% to 73.3% (χ2=9.033, P=0.003), and 25.0% to 53.3% (χ2=8.522, P=0.004), respectively.ConclusionApplication of nosocomial infection management system can increase the report of occupational exposure and the follow-up ratio of occupational exposure significantly.
ObjectiveTo understand the distribution characteristics and nosocomial infection of carbapenem-resistant Enterobacteriaceae (CRE) in a general hospital of traditional Chinese medicine, so as to provide the evidence for control and management of multidrug-resistant bacteria.MethodsData of CRE in the first Affiliated Hospital of Anhui University of Traditional Chinese Medicine were analyzed retrospectively from 2014 to 2018.ResultsThe total detection rate of CRE was 10.76%, 5.58%, 15.42%, 12.94% and 16.18% from 2014 to 2018, respectively. The detection rate of CRE showed a gradual upward trend (χ2=29.940, P<0.001). The highest number of CRE isolated from clinical specimens was sputum (355 strains, 63.39%), and the next were urine (98 strains, 17.50%) and secretions (38 strains, 6.79%). CRE isolated from different clinical departments were mainly in Neurosurgery Department (172 stains, 30.71%), Intensive Care Unit (Internal Medicine) (145 strains, 25.89%), Intensive Care Unit (Surgery)(106 strains,18.93%), and other internal medical departments (83 strains, 14.82%). A total of 179 patients developed CRE nosocomial infection in the past 5 years, who were mainly male, and with advanced age, long hospital stay, basic diseases, abnormal immune function and invasive operation. The incidence of hospital infection with CRE from 2014 to 2018 were 0.31‰, 0.38‰, 0.89‰, 0.80‰ and 1.14‰, respectively, which also showed a gradual upward trend (χ2=25.111, P<0.001).ConclusionWith the increasing number of clinically isolated CRE strains and the increasing incidence of nosocomial infection of CRE, effective intervention measures should be taken to prevent and control CRE.
