Background:
We implemented evidence-based interventions to reduce risk of surgical site infection (SSI) following low transverse cesarean section (LTCS).
Methods:
An observational study was conducted to determine LTCS SSI rates and the impact of infection control interventions at an academic teaching hospital during the period October 2005 to December 2008, including the use of 2% chlorhexidine gluconate (CHG) for surgical skin preparation before LTCS and no-rinse CHG cloths for preoperative skin cleansing. We compared overall and risk strata specific SSI rates and standardized incidence ratios during 4 study periods and estimated cost savings.
Results:
Of 1,844 LTCSs performed, 99 patients were identified with SSI. SSI rates per 100 LTCS declined from 6.27 at baseline and 10.84 during the outbreak period to 5.92 in intervention 1 period and 2.29 in intervention 2 period. Overall, a 63.5% reduction in SSI rate from baseline was achieved by ensuring compliance with SSI prevention guidelines and improving skin antisepsis (P = .003). In intervention 2 period, the standardized incidence ratio was 0.99 compared with 2.64 at baseline and 4.50 during the outbreak period.
Conclusion:
A multidisciplinary approach including evidence-based SSI prevention practices, effective infection prevention products, and staff and patient engagement substantially reduced infection risk and improved patient safety following LTCS.
