OBJECTIVE:To determine the rate and risk factors associated with central venous catheter (CVC)-associated bloodstream infections (BSIs) in Canadian intensive care units (ICUs).DESIGN:A prospective, active six-month cohort with a nested case-control study.SETTING:Forty-one ICUs located in 19 Canadian hospitals.METHODS:Data were collected using a standardized format on all CVCs and patients when a CVC was inserted for more than 48 h. Results of microbiological studies and therapeutic interventions were recorded when a BSI occurred.RESULTS:There were 182 BSIs from 3696 CVC insertions in 2531 patients. Coagulase-negative staphylococci were responsible for 73% of the BSIs. Mean rates of CVC-associated BSIs per 1000 CVC days were 6.9, 6.8 and 5.0 in adult, neonatal and pediatric ICUs, respectively. Significant factors associated with BSI included duration of CVC insertion (OR=1.2, 95% CI 1.1 to 1.3), receiving total parenteral nutrition (OR=4.1, 95% CI 1.2 to 14.3) and having one or more CVCs (OR=3.1, 95% CI 1.5 to 6.5). In the case-control study, 80% of the variance in a backward elimination logistic regression analysis was explained by duration of CVC insertion (OR=1.2 per day), receiving chemotherapy (OR=6.1), more than one CVC insertion during the study (OR=3.5), insertion of a CVC with two or more lumens (OR=2.3), using the CVC to administer total parenteral nutrition (OR=1.6) and having a surgical wound other than a clean wound (OR=1.6).CONCLUSION:The present study identified risk factors explaining 80% of the variance associated with BSIs and is one of the largest reports on the rate of CVC-associated BSIs occurring in the ICU setting.

AbstractObjective:To determine the risk factors for colonization or infection with methicillin-resistantStaphylococcus aureusin human immunodeficiency virus (HIV)-infected patients.Design:Retrospective matched-pair case-control study.Setting:Continuity clinic and inpatient HIV service of a university medical center.Population:Patients with HIV infection from the general population of eastern and coastal Texas and from the Texas Department of Criminal Justice.Data Collection:Patient charts and the AIDS Care and Clinical Research Program Database were reviewed for the following: age, race, number of admissions, total hospital days, presence of a central venous catheter, serum albumin, total white blood cell count and absolute neutrophil count, invasive or surgical procedures, any cultures positive forS aureus, and a history of opportunistic illnesses, diabetes, or dermatologie diagnoses. Data also were collected on the administration of antibiotics, antiretroviral therapy, steroids, cancer chemotherapy, and subcutaneous medications.Results:In the univariate analysis, the presence of a central venous catheter, an underlying dermatologie disease, lower serum albumin, prior steroid therapy, and prior antibiotic therapy, particularly antistaphylococcal therapy or multiple courses of antibiotics, were associated with increased risk for colonization or infection with methicillin-resistantS aureus. Multivariate analysis yielded a model that included presence of a central venous catheter, underlying dermatologie disease, broad-spectrum antibiotic exposure, and number of hospital days as independent risk factors for colonization or infection with methicillin-resistantS aureus.Conclusions:In our HIV-infected patient population, prior hospitalization, exposure to broad-spectrum antibiotics, presence of a central venous catheter, and dermatologie disease were risk factors for acquisition of methicillin-resistantS aureus

AbstractObjective:To characterize risk factors for Stenotrophomonas maltophilia bloodstream infection in oncology patients.Design:A 3:1 case–control study.Setting:Stem Cell Transplant and Leukemic Center at Barnes–Jewish Hospital (St. Louis), a 1,442-bed, tertiary-care teaching hospital with a 26-bed transplantation ward.Method:From June 1999 to April 2001,13 patients with S. maltophilia bacteremia were compared with 39 control-patients who were on the transplantation unit on the same day as the case-patients' positive blood cultures. Information collected included patient demographics, medical history, history of transplantation, transplantation type, graft versus host disease, neutropenia, antibiotic use, chemotherapy, mucositis, diarrhea, the presence of central venous catheter(s), cultures, and concomitant infections.Results:Significant risk factors for S. maltophilia bacteremia included severe mucositis (7 [53.8%] of 13 vs 8 [20.5%] of 39; P = .034), diarrhea (7 [53.8%] of 13 vs 8 [20%] of 39; P = .034), and the use of metronidazole (9 [69.2%] of 13 vs 8 [20.5%] of 39; P = .002). In addition, the number of antibiotics used (median, 9 vs 5; P < .001), duration of mucositis (median, 29 vs 15 days; P = .032), and length of hospital stay (median, 34 vs 22 days; P = .017) were significantly different between case- and control-patients. Nine S. maltophilia isolates tested by pulsed-field gel electrophoresis were found to be distinctly different.Conclusion:Interventions to ameliorate the severity of mucositis, reduce antibiotic pressure, prevent diarrhea, and promote meticulous central venous catheter care may help prevent S. maltophilia bloodstream infection in oncology patients. The role of gastrointestinal tract colonization as a potential source of S. maltophilia bacteremia in oncology patients deserves further investigation.

Objective.To evaluate the risk factors that influence time to acquisition of a laboratory-confirmed bloodstream infection (LCBI).Design.Prospective cohort study with an 18-month follow-up.Setting.A 16-bed medical and/or surgical pediatric intensive care unit that cares for patients of the Brazilian Public Health System exclusively.Patients.We included children from 0 to 18 years old who were represented by 875 consecutive admissions to the pediatric intensive care unit from January 1, 2005, through June 30, 2006. The children from all but 5 (0.6%) of the admissions were followed up until discharge or death. The majority (506 [58.2%]) were hospitalized for surgical pathology, and 254 (29.2%) underwent heart surgery.Methods.We used a standardized questionnaire and data collection from daily charts. Information on risk factors was collected before the onset of first LCBI. Survival analysis was performed using the Kaplan-Meier method. The effect of the variables on the risk of LCBI each day was estimated through a Cox model fitting.Results.Fifty-seven children (6.6%) developed an LCBI, 54 (94.7%) of whom made use of a central venous catheter. LCBI incidence was 11.27 episodes/1,000 patient-days and 17.92 episodes/1,000 patient-days when associated with a central venous catheter. Factors associated with time to the first LCBI in the Cox model were age less than 2 years (hazard ratio [HR], 1.99; 95% confidence interval [CI], 1.02–3.89), malnutrition (HR, 1.74; 95% CI, 1.01–3.00), use of a central venous catheter (HR, 4.36; 95% CI, 1.30–14.64), use of antibiotics before admission (HR, 0.58; 95% CI, 0.33–0.98), and use of transfused blood products (HR, 0.40; 95% CI, 0.22–0.74).Conclusion.Factors associated with time to acquisition of LCBI were age less than 2 years, weight-for-age z score less than −2, and the use of a central venous catheter. Therefore, intensification of LCBI prevention efforts in patients with these characteristics is fundamental.
