RCT of Postoperative Infections Following Caesarean Section Infections Following Caesarean Section
- Registration Number
- NCT02009098
- Lead Sponsor
- Odense University Hospital
- Brief Summary
Background Women undergoing Caesarean Section (CS) have an increased risk of postpartum infections compared to women undergoing vaginal delivery. In Denmark the incidence of post-CS infections is 7-10%. The most common infections are endometritis, Urinary tract infections (UTI) and wound infections (WI).
Prophylactic antibiotics are effective in preventing postoperative infections and national guidelines recommend that antibiotics should be administered as a single dose immediately before surgical incision. CS is an exception to this pre-incision administration approach. National guidelines recommend administration of antibiotics after umbilical cord clamping to avoid exposure of the child to antibiotics before birth. Recent studies of antibiotic prophylaxis for CS suggest that prophylactic antibiotics administered before incision compared to after umbilical cord clamping may reduce post-CS infections by up to 50%. Two Cochrane reviews from 2012 criticize these types of studies for lack of data for outcomes on the baby and on late infection in the mother.
This study is a double-blinded randomized controlled trial with a concurrent Health Economic Assessment. The study will examine the effect of change in timing of prophylactic antibiotics on the rate of post-CS infections (endometritis, UTI and WI). The study will be performed at the obstetric departments at Odense University Hospital (OUH), Hvidovre Hospital (HH) and Hospital South West Jutland (HSWJ) in collaboration with the Department of Clinical Microbiology, OUH, to ensure that the most appropriate antibiotic regime is used. Furthermore, collaboration with a neonatologist will ensure appropriate assessment of neonatal outcome.
The investigators plan to enroll the first patient at OUH February 2013. HH and HSWJ will follow with a couple of months delay. The inclusion period is scheduled to last until the investigators have 2844 participants, who have answered the questionnaire. The investigators expect to complete the inclusion period in October 2014 (last patient last visit, LPLV). Microbiological analyzes and data processing is expected to be completed one year after the LPLV. The study population is all women delivering a child by CS during the project period, at Department of Gynaecology and Obstetrics of OUH, HH and HSWJ.
Objective: Investigate whether and by how much antibiotics administered 15-60 minutes before incision versus after umbilical cord clamping reduces the rate of postpartum infections in a Danish population of women undergoing CS.
Hypothesis: Antibiotics administered pre-incision will result in fewer postoperative infections than antibiotics administered after the umbilical cord is cut.
Hypothesis: Antibiotics administered before incision are cost-effective, compared to administration after umbilical cord clamping, measured by post-CS infection and as cost per Quality Adjusted Life Year (QALY).

- Primary Outcome Measures
Name Time Method Women: The incidence of post-CS infection (endometritis, urinary tract infections, and wound infections) within the first 30 days after surgery To be able to collect information about symptoms of infection after discharge a self-administered questionnaire will be sent to all participants within 30 days post-CS. Furthermore data on postoperative infections, recorded by diagnoses codes or surgical procedures, will be obtained from the Danish National Patient Registry.
Infant: admission to special care unit participants will be followed for the duration of hospital stay, an expected average of 4 days
- Secondary Outcome Measures
Name Time Method Infant: antibiotic treatment during hospital stay participants will be followed for the duration of hospital stay, an expected average of 4 days Infant: the need for intensive care treatment and length of stay in hospital participants will be followed for the duration of hospital stay, an expected average of 4 days Infant: Neonatal sepsis participants will be followed for the duration of hospital stay, an expected average of 4 days Neonatal sepsis, Neonatal sepsis workup
Women: Number of Participants with Adverse Events as a Measure of Safety and Tolerability participants will be followed for the duration of hospital stay, an expected average of 4 days Adverse reactions/events registered during hospitalization (complications, examinations, treatments, antibiotic use)
Women: length of the primary and any secondary hospitalization within the first 30 days after Caesarean Section Women: readmissions to hospital/contact to the general practitioner on suspicion of infection after Caesarean Section within the first 30 days after Caesarean Section Women: antibiotic treatment on suspicion of infection after Caesarean Section within the first 30 days after Caesarean Section Infant: use of antifungal treatment against oral thrush participants will be followed for the duration of hospital stay, an expected average of 4 days Infant: necrotizing enterocolitis participants will be followed for the duration of hospital stay, an expected average of 4 days
