Improving the rate of pathogen examination before antibiotic treatment is of great significance for clarifying pathogen diagnosis and curbing bacterial resistance, and is also one of the important goals for improving national medical quality and safety. In response to the current problem of low pathogen examination rates, Chengdu Women’s and Children’s Central Hospital adopts a FOCUS-PDCA model, has explored measures such as current situation investigation, root cause analysis, intervention plan formulation, countermeasure implementation, and effect evaluation to improve the rate of pathogen examination before antibiotic treatment in inpatients. This article mainly elaborates on the above model, which has practical significance for ensuring the rational use of antibiotics in inpatients.
ObjectiveTo explore the risk factors for surgical patients associated with postoperative nosocomial infection through monitoring the infection conditions of the patients, in order to provide a scientific basis for the development of hospital infection control measures in a second-grade class-A hospital in Chengdu City. MethodsWe conducted the survey with cluster sampling as the sampling method and the uniform questionnaire in the departments of orthopedic, neural and thoracic surgery from July 2011 to June 2012. The main parameters we observed were the patients'general and surgical conditions, antibiotics usage and hospital infection situation. Data were analyzed using the National Nosocomial Infection Surveillance Network software and chi-square test of single factors. ResultsIn this survey, we monitored 50 cases of postoperative hospital infection. The infection rate was 7.73% and the highest infection rate was in the Neurosurgery Department. The main site of infection was lower respiratory tract, followed by surgical site. The different usage time of antimicrobial drug in perioperative period resulted in different infection rates, and the difference was statistically significant (χ2=601.50, P<0.005). The rate of adjusted postoperative hospital infection was higher than pre-adjusted rate except that of the neurosurgery doctor 4. The risk factors associated with hospital postoperative infection in our hospital were:patients'conditions including underlying disease, emergency surgery, type of anesthesia, operative duration, hospital stay and postoperative drainage. Most of the hospital infection cases were caused by bacteria of the gram-negative bacilli, and the major pathogens were Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter baumannii in our hospital. ConclusionThe hospital should particularly strengthen the prevention and control of hospital infection in patients after neurosurgical operations. For patients with basic diseases, we should actively improve the patients'physical conditions before operation and control the primary lesion. Targeted control measures should be taken for different factors related to surgery. Reasonable selection of antimicrobial agents should be based on the epidemic strains in our hospital.
ObjectivesTo systematically review the efficacy of prophylactic antimicrobial use on preventing infections after arthroscopy.MethodsPubMed, EMbase, The Cochrane Library, CNKI, CBM and WanFang Data databases were electronically searched to collect clinical studies on the efficacy of prophylactic antimicrobial use on preventing infections after arthroscopy from January 1990 to September 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies; then, meta-analysis was performed by using RevMan 5.3 software and Stata 15.0 software.ResultsA total of 8 retrospective cohort studies and 1 randomized controlled trial involving 60 136 subjects were included. The results of the meta-analysis showed that: there was no difference in the post-operational infection rate among patients with and without antimicrobial prophylaxis for arthroscopies (OR=0.51, 95%CI 0.25 to 1.04, P=0.06). For knee arthroscopies, the post-operational infection rate had no difference between patients with and without antimicrobial prophylaxis (OR=0.89, 95% CI 0.65 to 1.23, P=0.48). However, for shoulder arthroscopies, the post-operational infection rate in the antimicrobial prophylaxis group was significantly lower than that in the group without the antimicrobial prophylaxis(OR=0.18, 95%CI 0.08 to 0.37, P<0.000 01).ConclusionsCurrent evidence shows that there is no association between preoperative antimicrobial prophylaxis and a decreased infection rate for knee arthroscopies. Antimicrobial prophylaxis appears to lead to fewer infections after shoulder arthroscopies. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
Objective To analyze the clinical characteristics and risk factors of noninfectious fever after endovascular repair of aortic dilatation diseases, and explore the management strategy. Methods We reviewed 468 patients who received endovascular aortic repair from January 2021 to October 2023. The patients who were selected were classified into a febrile group and an afebrile group according the fever after operation. The fever data were analyzed, and the demographics, operative data were researched to sieve out the correlation factors. Logistic regression analysis was conducted for the risk factors of postoperative fever if the P value≤0.05 in the univariate analysis, and receiver operating characteristic curve (ROC) was used to analyze the predictive indexes of postoperative noninfectious fever. Results75.08% (229/305) patients had noninfectious fever after aortic repair and 98.25% of them had fever within 2 days. There were 229 patients in the febrile group, mean age 65 (53.0,73.0) years (83.4% males , and 76 patients in the afebrile group, mean age 71(65.0,76.7) years(84.2% males). Univariate analysis showed that the number of patients with coronary heart disease, using statins before operation and aortic aneurysm in the febrile group were significantly lower than those in the afebrile group, and patients were younger in the febrile group. The logistic regression showed that age, surgical site, type of disease, preoperative hyperthermia, type of stent were positively correlated with noninfectious fever, while statin use was negatively associated with noninfectious fever. And age, surgical site, preoperative hyperthermia and stent type were analyzed by means of ROC curve (P<0.01). Conclusion Noninfectious fever is very common after aortic repair. The relationship between fever and infection should be comprehensively judged according to the risk factors of noninfectious fever and the disease status to promote rational use of antibiotics.
ObjectiveTo investigate the status of antibiotic drug use in the outpatient department based on the special rectification activities of antibiotic drugs, identify the reasons for irrational use of antibiotic agents and propose the solutions. MethodsPrescription of antibiotic drugs were analyzed by a retrospective comparative analysis during April to June 2011, August to October 2011 and August to October 2012. ResultsPrescriptions of antibiotic drugs were 435 (36.25%), 367 (30.58%) and 223 (18.58%) during April to June 2011, August to October 2011 and August to October 2012, respectively, and the unreasonable prescriptions were 35 (2.92%), 27 (2.25%), and 14 (1.25%) respectively. ConclusionThere is a decreased tendency of prescription of antibiotic drugs in the outpatient department of our hospital because of the special rectification activities of antibiotic drugs. It is in accordance with antibiotic use rate of <20% target of "antibiotics in 2012 special rectification program" in hospital outpatient service. But there are some unreasonable phenomena in the use of antibiotics, and to promote the reasonable use of antibiotics, we should strengthen management.
Renal cancer is a common malignant tumor and the deadliest cancer of the urinary and reproductive system. Given the increasing incidence rate of kidney cancer, timely intervention of its controllable risk factors is crucial. Antimicrobial agent is widely used worldwide, and in recent years, some studies have found that long-term use of antimicrobial agent is associated with an increased risk of kidney cancer. The mechanism may involve multiple factors such as nephrotoxicity of antimicrobial agent and intestinal flora imbalance. This article reviews the relationship between long-term use of antimicrobial agent and risk of kidney cancer, and explores possible mechanisms, to understand the impact of long-term use of antimicrobial agent on the risk of kidney cancer, and to provide more references for early prevention of kidney cancer and rational use of antimicrobial agent.
