术后切口感染危险因素的病例对照研究 总被引:4,自引:0,他引:4
本研究对某医院1992年7月~1993年9月期间住院的外科病人术后切口感染及其危险因素进行了前瞻性监测研究,共监测外科住院病人4298例,其中153例手术病人发生术后切口感染,2635例手术病人未发生任何部位的医院感染。应用成组的病例对照研究方法,通过单因素分析,发现切口分类、术前预防应用抗生素、暴露于ICU、导尿、动、静脉插管、术中使用呼吸机、手术时间、引流和术后切口感染有显著的联系。Logistic回归分析筛选出了5个互相独立的与术后切口感染有显著联系的因素,它们是术前预防应用抗生素、引流切口分类、手术时间≥2小时、暴露于ICU,但术前预防应用抗生素与术后切口、感染呈负相关。 相似文献

OBJECTIVE: To investigate the effect of preoperative initiation of low molecular weight heparin as prophylaxis for deep venous thrombosis in patients at risk of developing surgical-site infections after knee arthroplasty. DESIGN: Case-control study nested in a cohort. The incidence of surgical-site infection in the cohort was calculated. With the use of data extracted from medical histories and after adjustment for other risk factors, the effect of preoperative heparinization on the risk of incisional and prosthetic infection among case-patients and control-patients (1:3 ratio) was assessed. SETTING: Orthopedic department in a tertiary-care referral hospital. PATIENTS: A cohort of 160 consecutive patients who had received prosthetic knee implants between October 1, 2001, and November 30, 2003. RESULTS: Eighteen patients with surgical-site infections were identified, yielding an incidence of incisional and prosthetic infection of 6.9 (95% confidence interval [CI95], 3.5 to 12.0) and 4.4 (CI95, 1.8 to 8.8) cases per 100 patients undergoing surgery, respectively. Surgical-site infection was associated with preoperative use of low molecular weight heparin (odds ratio [OR], 6.2 after adjustment for medical and surgical factors; CI95 1.5 to 23). Prosthetic infection was strongly associated with preoperative use of prophylaxis (OR, undetermined [100% exposure in case-patients vs 35% exposure in control-patients]; P = .002), but incisional surgical-site infection was not. CONCLUSION: The use of low molecular weight heparins immediately before knee arthroplasty as prophylaxis for deep venous thrombosis should be questioned because of probable increased risk of prosthetic infection. 相似文献

During one year, 1,407 operations were performed on inpatients in an orthopaedic department. The presence or absence of postoperative wound infection was recorded during the hospital stay, at discharge and at follow up. Wound infections were linked to operations of different contamination categories and to the different types of operation performed. Better information about the risk for postoperative wound infection and the need for antibiotic prophylaxis was provided by considering the different operation types. 相似文献

Incidence, risk factors and outcome of infection in a 1-year hysterectomy cohort: a prospective follow-up study 总被引:3,自引:0,他引:3
Meltomaa SS Mäkinen JI Taalikka MO Helenius HY 《The Journal of hospital infection》2000,45(3):211-217
A prospective study was performed following 687 patients who underwent abdominal, vaginal and laparoscopic hysterectomy for benign conditions in Turku University Hospital. This study evaluates and compares infection after hysterectomy and determines risk factors associated with postoperative infection. Infective episodes were recorded during hospital stay, convalescence for 4 to 6 weeks at home and for 1 year of follow-up. Factors found to be statistically significant for hospital-acquired infection on univariate analysis were subsequently assessed by means of multivariate analysis. During the hospital stay 23.7% of the study population became infected, 38.1% after vaginal hysterectomy, 23.4% after abdominal hysterectomy and 3.0% after laparoscopic hysterectomy. Over half of all hospital-acquired infections were lower urinary tract infections. Infection during convalescence occurred in 19.2% of patients: 29.5% in the vaginal hysterectomy group, 17.4% in the abdominal hysterectomy group and 16.7% in the laparoscopic hysterectomy group. One year of follow-up did not find any infection directly attributable to surgery. Five factors were found to be related to in-hospital infection on multivariate analysis. These were lack of antibiotic prophylaxis, blood loss during operation, intermittent catheterization, anaemia and medication for urinary or bowel dysfunction after operation. 相似文献

Objective: to assess the risk of surgical wound infection and hospital acquired infections among patients with and without adequate antibiotic prophylaxis. Also, to provide models to predict the contributing factors of hospital infection and surgical wound infection. Design: survey study. Prospective cohort study over 14 months, with data collected by a nurse and a epidemiologist through visits to the surgical areas, a review of the medical record and consultation with the medical doctor and nurses attending the patients. Setting: Two hundred and fifty bed, general hospital serving Puertollano (Ciudad Real), population – 50,000. Results: between February 1998 and April 1999, 754 patients underwent surgery, 263 (34.88%) received appropriate peri-operative prophylaxis while 491 (65.12%) received inadequate prophylaxis. For those who received adequate antibiotic prophylaxis, the percentage of nosocomial infection was 10.65% compared with the group who received inadequate prophylaxis in which the percentage of nosocomial infection was 33.40%. The relative risk of nosocomial infection was, therefore, 4.21 times higher in the latter group (confidence intervals 95%: 2.71–6.51). A patient in the inadequate prophylaxis group had a 14.87% chance of wound infection while a patient in the adequate prophylaxis group had a 4.56% chance of wound infection. The relative risk of wound infection was 3.65 times higher in the group that received inadequate prophylaxis (confidence intervals 95%: 1.95–6.86). The final regression logistic model to assess nosocomial infection incorporated seven prognostic factors: age, length of venous periferic route, vesicle catheter, duration of operation, obesity, metabolic or neoplasm diseases and adequate or inadequate prophylaxis. When we incorporated these variables in the multi-factorial analysis we found that the relative risk of developing nosocomial infection was 2.33 times higher in the group which received inadequate prophylaxis. When we applied the second logistic multiple regression model (wound infection), we discovered that the probability of developing surgical wound infection was 2.32 times higher in the group which received inadequate prophylaxis as opposed to the group, which received adequate prophylaxis. The goodness of fit (Hosmer–Lemeshow test) showed a correct significance in all models. Conclusions: a multi-factorial analysis was applied to identify the high-risk patients and the risk factors for postoperative infections. Through the application of these multiple regression logistic models, we conclude that the correct antibiotic prophylaxis is effective and will subsequently reduce postoperative infection rates, especially in high-risk patients. Therefore, the choice of antimicrobial agent should be made on the basis of the criteria of hospital committee. 相似文献

To test the hypothesis that extended antibiotic prophylaxis increases the risk of Clostridium difficile -associated diarrhoea (CDAD), we conducted a retrospective cohort study of 2641 patients under-going cardiovascular surgery. Main outcome measures were the duration of prophylaxis (< 48 h vs. > 48 h) and the occurrence of CDAD. CDAD occurred in 31 patients (1.2%), who were significantly older (70 +/- 9 y vs. 66 +/- 10 y; P = 0.03), received more therapeutic antibiotics (2.2 +/- 1.9 vs. 0.4 +/- 0.9; P = 0.001) and had a longer postoperative hospital stay (26 +/- 19 d vs. 9 +/- 8 d; P < 0.001) than non-cases. After adjusting for confounding, we did not observe an association between prolonged prophylaxis and CDAD [adjusted odds ratio (AOR), 0.8; CI, 0.4-1.8]. In contrast, three independent predictors were identified: increasing length of hospital stay (AOR per one-day-increment, 1.03; CI, 1.01-1.05), and treatment with third generation cephalosporins (AOR, 5.9; CI, 2.2-16.0) or beta-lactam-beta-lactamase inhibitor combinations (AOR, 4.6; CI, 1.7-12.3). Our results did not confirm that extended prophylaxis after clean surgery increases the risk of CDAD, which remains an uncommon postoperative complication, associated even with short antibiotic exposure. 相似文献

Nosocomial infections and misuse of antibiotics in a provincial community hospital, Saudi Arabia 总被引:2,自引:0,他引:2
The incidence of nosocomial infection and prevalence of antibiotic misuse were studied in a 174-bed community hospital in Saudi Arabia over a six-month period. Of 2445 patients admitted, 8.5% developed nosocomial infection, the rates were highest for nursery (35.8%), intensive care (19.8%), gynaecological (16.2%) and surgical (11.7%) patients. Urinary tract (31.3%), wound (27.1%) and blood (14.9%) infections accounted for more than 70% of the infections. Staphylococcus aureus (23%) and Pseudomonas aeruginosa (11%), caused more than 90% of the infections. The majority of the bacterial pathogens (79%) were multi-drug resistant. Over 80% of patients were administered prophylactic and/or therapeutic antibiotics, with 53% receiving multiple antibiotics; 72% of the antibiotics were judged to be misused. Both prophylaxis and treatment were mostly misguided and clinically unwarranted. Host- and hospital-associated infection risk factors were identified. The minimum government cost estimates for the nosocomial infections and misused antibiotics were US $273 180 and $565 603, respectively. The findings emphasize the need for effective measures to reduce both the high infection rates and widespread antibiotic misusage in the hospital. Such measures should include institution of an effective infection control committee and a hospital antibiotic policy. 相似文献

OBJECTIVE: To study the relation of preoperative infected urine and postprostatectomy wound infection in patients with and without indwelling bladder catheters. DESIGN: Patients undergoing prostatectomy were evaluated for the presence of infected urine prior to prostatectomy and postoperative wound infection. They were further divided into patients with indwelling urinary catheter and catheter-free patients. All had received antibiotic prophylaxis. PATIENTS: One hundred fifty consecutive patients undergoing open prostatectomy--mean age was 67 years; 100 patients with an indwelling catheter for a mean period of 50 days; 50 catheter-free patients. RESULTS: Wound infection was found in 19 of 81 (23.5%) and in 6 of 69 (8.7%) patients with infected and sterile urine, respectively (p = .028). In patients with indwelling catheters prior to operation, wound infection was 22.4% when urine was infected and 8.3% when it was not. In patients without catheters, infected urine was associated with 40% of wound infections, as compared with 8.9% of wound infections in patients with sterile urine. Organisms obtained from infected wound and urine were identical in 84% of cases. These results were obtained despite antibiotic prophylaxis. CONCLUSIONS: Wound infection has been demonstrated to be a postprostatectomy complication directly related to the presence of urinary infection at surgery; thus, elective prostatectomy should be deferred until urine becomes sterile. 相似文献
