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 role of dynamic monitoring procalcitonin (PCT) in the comprehensive evaluation during the diagnosis and treatment of community acquired pneumonia (CAP). MethodsFour hundred and sixty-eight patients with CAP were randomly assigned to a PCT-guided group (the research group) and a standard guideline group (the control group). The clinical symptoms,CURB-65 grade,blood leucocyte count and classification,and C-reactive protein (CRP)were compared between two groups. The PCT-guided application time of antibiotics,the hospitalization time,chest CT examination rate,the cure or the improvement rate were also estimated and commpared. ResultsThe hospitalization time [(9.6±1.7)days vs. (10.9±1.6)days],hospitalization cost [(6 957.11±1 009.46) yuan vs. (8 011.35±1 049.77) yuan],chest CT examination rate (56.96% vs. 89.40%),the application time of antibiotics [(16.5±2.3)days vs. (20.0±1.2)days],and the rate of required antibiotics upgrade (6.96% vs. 11.06%) in the research group were all significantly lower than the control group (P<0.05). There was no significant difference between two groups in the ratio of the adverse reaction of antibiotics (14.78% vs. 15.20%),the rate of transfer into ICU (2.61% vs. 3.69%) or the mortality (1.74% vs. 2.30%)(P>0.05). ConclusionOn the basis of CAP guidelines,the dynamic monitoring of PCT may shorten the time of antibiotic use and the hospitalization,reduce the cost of hospitalization and the rate of chest CT scan in patients with CAP.
Based on review and practice of literature search of clinical economic evaluation, We have discussed the source and search strategy of literatures of clinical economic evaluation. A sample on antibiotics in the treatment of community-acquired pneumonia was shown concurrently.
Objective To evaluate systematically the effect of antibiotic treatment on ventilator-associated tracheobronchitis (VAT). Methods Pubmed,Web of Science,OVID SP (ACP Journal Club,Cochrane Central Register of Contralled Trials,Embase,Medline),as well as China National Knowledge Infrastructure,China Science and Technology Journal Database,and Wanfang Data were searched for literatures about antibiotic treatment on VAT.The search deadline was March 2016.Meta-analysis was conducted with RevMan 5.3 software. Results A total of 6 studies with 769 patients were included.Among 769 patients,432 patients were treated by antibiotics,and 337 patients in control group were treated without antibiotics.Meta-analysis showed antibiotics treatment significantly reduced incidence of ventilator-associated pneumonia compared with control group [OR=0.27,95%CI (0.17,0.43),P<0.05],and shortened length of ICU stay [MD -1.51,95%CI(-2.04,-0.98),P<0.00001] .There were no significant difference in duration of mechanical ventilation [MD -2.52,95%CI (-6.85,1.81),P=0.25],mortality [OR=0.41,95%CI(0.15,1.14),P=0.09],or drug-resistant bacteria production [OR=0.62,95%CI(0.17,2.19),P>0.05]. Conclusions Antibiotic treatment can reduce incidence of ventilator-associated pneumonia in patients with VAT.Further more high quality randomized controlled trials are needed to assess the effect of antibiotic treatment on VAT.
ObjectiveTo understand the characteristics of and risk factors for nosocomial infection in a newly built branch of a university teaching hospital, in order to investigate the control measures for prevention and control of nosocomial infection. MethodsA total of 598 cases of nosocomial infection from April 2012 to June 2014 were enrolled in this study. We analyzed statistically such indexes as nosocomial infection rate, infection site, pathogen detection, and use of antibiotics. Meantime, infection point-prevalence survey was introduced by means of medical record checking and bedside visiting. ResultsAmong all the 44 085 discharged patients between April 2012 and June 2014, there were 598 cases of nosocomial infection with an infection rate of 1.36%. Departments with a high nosocomial infection rate included Intensive Care Unit (ICU) (9.79%), Department of Orthopedics (2.98%), Department of Geriatrics (2.62%), and Department of Hematology (1.64%). The top four nosocomial infection sites were lower respiratory tract (45.32%), urinary tract (13.21%), operative incision (8.86%), and blood stream (8.86%). The samples of 570 nosocomial infections were delivered for examination with a sample-delivering rate of 95.32%. The most common pathogens were acinetobacter Baumanii (17.02%), Klebsiella pneumoniae (14.21%), Escherichia coli (13.68%), Pseudomonas aeruginosa (11.93%), and Staphylococcus aureus (9.12%). And urinary tract intubation (42.81%), admission of ICU (28.60%), and application of corticosteroid and immunosuppressive agents (26.42%) were the top three independent risk factors for nosocomial infection. ConclusionGeneral and comprehensive monitoring is an effective method for the hospital to detect high-risk departments, factors and patients for nosocomial infection, providing a theoretical basis for prevention and control of nosocomial infection.
Objective To evaluate systematically the effectiveness and safety of procalcitonin ( PCT) -guided therapy in comparison with standard therapy in patients with suspected or confirmed severe bacterial infections in intensive care unit ( ICU) . Methods Five randomized controlled trials ( 927 patients) were included for statistical analysis by the cochrane collaboration′s RevMan5. 0 software. Results PCT-guided therapy was associated with a significant reduction in duration of antibiotic therapy [ MD =- 2. 01, 95% CI ( - 2. 37, - 1. 64) , P lt;0. 00001] , but the mortality [ OR =1. 11, 95% CI ( 0. 83, 1. 49) ,P =0. 47] and length of ICU stay[ MD = 0. 49, 95% CI( - 1. 44, 2. 42) , P = 0. 62] were not significantly different. Conclusions An algorithmbased on serial PCT measurements would allow a more judicious use of antibiotics than currently traditional treatment of patients with severe infections in ICU. It can reduce the use of antibiotics and appears to be safe.
ObjectiveTo investigate the antibacterial pretreatment protocol for primary fibroblast cell culture from transbronchial biopsies in patients with benign tracheal stenosis (BTS). MethodsFifteen specimens of intratracheal hyperplastic granulation tissue were obtained from 14 BTS patients by transbronchial biopsies. The tissues were divided into 3 groups according to different antibacterial pretreatment with 5 specimens in each group. An usual concentration of antibiotics pretreatment group (group 1) was pretreated by washing with PBS contained 1%-2% penicillin/streptomycin. A high concentration of antibiotics pretreatment group (group 2) was pretreated by washing with PBS contained 6% penicillin/streptomycin. An alchohol and high concentration of antibiotics pretreatment group (group 3) was pretreated by washing with 75% alcohol 3-4 seconds firstly,then by washing with 6% penicillin/streptomycin. After different pretreatment,all tissues were cultured with tissue culture method in the same condition. ResultsThe primary fibroblasts were successfully cultured from the tissue pretreated by method 2 and 3,but not cultured from the tissue pretreated by method 1 with large amount of bacteria. There were significant differences in the furthest radius of cell proliferation between different culture time points in three groups (P<0.01). The differences in the furthest radius of cell proliferation between three groups were not different at 24,48 or 72 h (P>0.05),but were significant between three groups at 96 h (P<0.05). ConclusionAn pretreatment protocol with high concentration of antibiotics or 75% alcohol is feasible in human primary fibroblasts culture from small specimens obtained by transbronchial biopsy.
ObjectiveTo evaluate rational use of antibiotics for hernioplasty in perioperative period by intervention-control study in order to provide a foundation for the clinical antibiotic use and management. MethodsThe data of the preventive use of antibiotics for hernia patients from January to October, 2010 in perioperative period were collected and compared. Interventions on patients from January to October, 2011 were carried out. ResultsIn the intervention group, the first three antibiotics used were changed from azlocillin, mezlocillin and aztreonam before intervention to cefazolin, clindamycin and azlocillin after intervention. Before intervention, antibiotics were first used after surgery for surgical prophylaxis, while after intervention, antibiotics were first used within 30 minutes before surgery or at the start of induction of anesthesia. The preventive medication time decreased from (3.50±2.07) days to (0.88±1.07) days (t'=14.601, P=0.000), the hospitalization days of post-surgery decreased from (5.17±1.90) days to (3.77±1.61) days (t'=7.313, P=0.000), the cost of antibiotics decreased from (342.39±415.50) yuan to (54.08±80.83) yuan (t'=8.831, P=0.000), the percentage of the cost of antibiotics in expenses for medicine declined from (47.53±25.51)% to (12.49±13.46)% (t'=15.776, P=0.000), and the percentage of the cost of antibiotics in hospitalization expenses declined from (6.59±5.49)% to (1.07±1.35)% (t'=12.662, P=0.000). The difference in inappropriate use of antibiotic drugs before and after prevention, such as choice of preventive drugs, preoperative medication occasion, course of postoperative medication and no indication of drug combination, had statistical significances (P<0.05). ConclusionThe intervention-control study shows that the rational use of antibiotics for hernioplasty in perioperative period can be improved, and the average hospitalization days and the cost of antibiotics can be reduced by intervention.
ObjectiveTo systematically review the clinical efficacy and safety of glucocorticoids, acetaminophen and antimicrobial drugs in the treatment of intrapartum fever in labor analgesia. MethodsThe PubMed, Embase, Cochrane Library, Web of Science, CBM, VIP, and CNKI databases were electronically searched to collect randomized controlled trials (RCTs) of glucocorticoids, acetaminophen, and antimicrobial drugs for intrapartum fever in labor analgesia from inception to June 30, 2023. Two reviewers independently screened the literature, extracted data, and evaluated the risk of bias of the included literature. Meta-analysis was then performed by using RevMan 5.4 software. ResultsA total of 10 RCTs involving 1 337 women were included. Meta-analysis showed that the use of glucocorticoids reduced the incidence of intrapartum fever in women with labor analgesia compared with the control group (OR=0.52, 95%CI 0.33 to 0.82, P<0.01). But there was no statistically significant difference between acetaminophen or antimicrobial drugs and the control group. ConclusionCurrent evidence shows that the use of glucocorticoids can reduce the incidence of intrapartum fever in labor analgesia, but the use of acetaminophen and antimicrobial drugs cannot reduce the incidence of intrapartum fever. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
Objective To investigate the spectrum of diseases and the current situation of antibiotic use in rural hospitals and community health service centers in Chengdu, so as to provide evidence for selecting essential medicines and promoting rational use of antibiotics. Method We selected 7 township/community health institutions, from which we collected inpatient and outpatient information. Information about antibiotic use was also collected, including categories, cost, and dosage. A standard questionnaire was used to investigate physicians’ prescription behavior for principal diseases. Result Urban and rural areas had different spectrums of diseases. The major diseases in urban areas included diabetes mellitus, hypertension, chronic obstructive pulmonary disease, and respiratory tract infection; while those in rural areas were infectious diseases of the respiratory system, digestive system, and urinary system. The physicians’ prescription behavior was mainly based on their personal experience. Antibiotics accounted for 30-50% of the total medicine cost. The top four types of antibiotics with the highest cost were cephalosporins, penicillin, quinolones, and macrolides. Conclusion Based on the different spectrums of diseases, essential drug lists and standard treatment guidelines appropriate for rural health care should be developed to improve the rational use of drugs. Factors such as the average cost of daily dose and the course of treatment should be taken into consideration to reduce the overall cost of medicine. An antimicrobial resistance monitoring system and special training courses on rational use of antibiotics should be utilized in the rural health institutions.
