Use of surveillance data to calculate the sample size and the statistical power of randomized clinical trials testing Staphylococcus aureus vaccine efficacy in orthopedic surgery.

Background: Patients undergoing primary total hip arthroplasty (THA) would be a worthy population for anti-staphylococcal vaccines. The objective is to assess sample size for significant vaccine efficacy (VE) in a randomized clinical trial (RCT).

Methods: Data from a surveillance network of surgical site infection in France between 2008 and 2011 were used.

The "RESEAU MATER": An efficient infection control for endometritis, but not for urinary tract infection after vaginal delivery.

"RESEAU MATER" is useful to monitor nosocomial infections in maternity and contributes to the decreasing trend of it, since its implementation. Specifically, this network demonstrates its efficiency in the control of endometritis following vaginal deliveries, but not in the control of urinary tract infections. The aim of this study is to determine whether the difference between the control of endometritis and of urinary tract infection could be explained by an unsuitable regression model or by an unsuitable care policy concerning urinary cares.

Compliance with standard precautions: Results of a French national audit.

Background: Standard precautions (SPs) aim to reduce the risk of cross-transmission of microorganisms. The objectives of the present study were to assess institutional policies for SPs promotion, available resources for SPs implementation, and education of health care workers (HCWs) and their compliance with SPs.

Methods: A multisite mixed-methods audit was conducted in 2011.

Maternal infection rates after cesarean delivery by Pfannenstiel or Joel-Cohen incision: a multicenter surveillance study.

Objective: Our purpose was to evaluate maternal nosocomial infection rates according to the incision technique used for caesarean delivery, in a routine surveillance study.

Study Design: This was a prospective study of 5123 cesarean deliveries (43.2% Joel-Cohen, 56.

Reduction of urinary tract infections acquired in an intensive care unit during a 10-year surveillance program.

Purpose: To describe trends of urinary catheter-related infections (UCRIs) acquired by patients hospitalized in intensive care units (ICU) in relation with an infection control program.

Materials And Methods: Prospective surveillance in one ICU of a university hospital in Lyon (France) between 1995 and 2004.

Results: A 66% reduction of urinary catheter-related infections (UCRIs) acquired by patients hospitalized was observed between 1995 and 2004 after adjustment on age, gender, antibiotic use at admission, and duration of exposure to urinary catheter.
