Reducing Surgical Site Infections Post-Caesarean Section

Background: Surgical Site Infections (SSI) are one of the most common complications after a caesarean with significant morbidity. Evidence suggests that SSI rates can be reduced post caesarean by using a Leukomed (R) Sorbact (R) (Essity) bacteria binding wound dressing, thereby reducing bacterial wound colonisation. Barking, Havering & Redbridge University Hospitals NHS Trust, London, UK (BHRUT) maternity unit sought change their clinical practice by using Leukomed Sorbact and evaluate if this reduced their SSI rate, SSI readmission rate, antibiotic usage and evaluate any associated cost savings. Methods: From January 1st 2022, Mepore (R) (Molnlycke) wound dressings were replaced with Leukomed Sorbact for all caesareans. Retrospective and prospective audits were undertaken to compare SSI incidence pre- and post- implementation of the dressing. No changes were made to wound cleaning products, prophylactic antibiotic use or surgical technique. Wound closure technique remained the choice of the individual surgeon. Results: Prior to this practice change, the baseline SSI rate between January-December 2021 was 6.1% and the SSI readmission rate was 1.27%. Comparative data for January-December 2022 showed a 38% reduction in SSI rates (overall SSI rate = 3.8%), a 31% reduction in readmission rate for SSI (overall rate = 0.88%), a 38% reduction in readmission bed days and a 30% reduction in antibiotic use. There was a reduction in SSI rates in all body mass index (BMI) categories. Total savings due to the reduction in SSI rates over twelve months were 234,784 pound. The cost savings to BHRUT solely attributable to the reduction in readmissions was 49,750 pound or 21 pound per Caesarean, which will be an ongoing saving. Conclusion: The use of Leukomed Sorbact dressings after Caesarean resulted in improved clinical outcomes with reduced SSI and readmission rates. Investment in the new dressing was cost effective when considering bed days freed, the reduction in antibiotic usage, reduced morbidity and improved patient experience.
