Filter by:Background: Hospital acquired pneumonia (HAP) is divided in two distinct groups, ventilator-associated pneumonia (VAP) and non-ventilator-associated HAP (nvHAP). Although nvHAP occurs more frequently than VAP and results in similar mortality and costs, prevention guidelines and prevention focus almost exclusively on VAP. Scientific evidence about nvHAP prevention is scarce. Therefore, we designed a mixed-methods study to investigate the effectiveness of a newly developed nvHAP prevention bundle and factors that influence its implementation. Methods: This single-centre project at the 950-bed University Hospital Zurich (UHZ) will engage the wards of nine departments with substantial nvHAP rates. The nvHAP bundle consists of five primary prevention measures: 1) oral care, 2) identification and treatment of patients with dysphagia, 3) mobilization, 4) stopping unnecessary proton pump inhibitors, and, 5) respiratory therapy. Implementation includes the engagement of department-level implementation teams, who sustain the 'core' intervention components of education, training, and environmental restructuring and adapt the implementation strategy to local needs. The effects of the implementation will be analysed by a mixed-method approach. As primary outcome, nvHAP incidence rates will be analysed by Poisson regression models to compare incidence rates before, during, and after the implementation phases (on the hospital and department level). In addition, the association between process indicators and nvHAP incidence rates will be analysed using longitudinal Poisson regression models. A longitudinal, qualitative study and formative evaluation based on interviews and focus groups identifies supporting or hindering factors for implementation success in participating departments dynamically over time. This accumulating implementation experience will be constantly fed back to the implementation teams and thus, represents an active implementation element. Discussion: This comprehensive mixed-methods study is designed to accomplish both, measure the effectiveness of a new prevention bundle against nvHAP and provide insights into how and why it worked or failed. The results of this study may contribute substantially to patient safety in the area of a rediscovered healthcare-associated infection - nvHAP.
Surgical site infections are common and a cause of major morbidity. They are also more common in obese women. Cesarean sections are the most common surgery performed in the United States, therefore pregnant women are being faced with this problem frequently. There is evidence to show that prophylactically administered antibiotics, cefazolin specifically, to obese women prior to cesarean section do not reach adequate concentrations in adipose tissue to prevent infection. The purpose of this study is to evaluate if an increased dose of cefazolin will attain adequate tissue concentration in obese women. Our hypothesis is that three grams of cefazolin given no more than 60 minutes prior to the start of a cesarean section in an obese (Body mass index (BMI) greater than or equal to 30) woman will attain adequate adipose tissue concentration compared to two grams of cefazolin. Subjects will be selected if they are greater than 37 weeks gestation wiht a singleton pregnancy and require a cesarean section for any obstetrical indication. Women will be excluded if they have a suspected infection, have a multiple gestation, or have preexisting diabetes or hypertension with end organ damage. The subjects will be screened both by through the OR schedule as well as through the clinics. They will then be consented and enrolled by the primary investigator. Once enrolled the subjects will be randomized to receive either two grams or three grams of cefazolin as prophylactic antibiotics to be given no more than 60 minutes prior to the start of the surgery. Two adipose tissue samples will be obtained at the time of surgery. The first at the start after skin incision and the second at the end prior to closure of the skin. There will also be a separate IV placed at the start of the procedure from which three blood draws can be collected. These three samples will be obtained at the start of the surgery but after antibiotic administration, at the time of the first adipose collection, and at the time of the second adipose collection. The samples will then be stored at -80 degrees and shipped to David P. Nicolau's lab in Hartford, CT for the tissue and serum analysis. While the subjects are in the hospital recovering from their surgery, a chart review will be performed to determine if there are any infections occuring post-operatively. A telephone survey will be conducted six to eight weeks postpartum again assessing for any infectious complications after the cesarean section.
The primary purpose of the study is to determine if a therapeutic difference exists between central venous catheters impregnated with minocycline and rifampin and conventional catheters not impregnated with antibiotics when used in children at high risk for bloodstream infections (CABSI) after cardiac surgery.
