| Summary: | Background Antimicrobial stewardship programs (ASP) aim to improve appropriate antimicrobial use but few studies have described its impact on unique population such as obstetrics. Post-operative antibiotics are unnecessary especially in those without surgical site infections (SSI) risk factors (e.g., obesity). Objectives To evaluate the impact of ASP interventions on post-elective caesarean (eLSCS) oral antibiotic prophylaxis rates and patient outcomes. Methods This pre-post quasi-experimental study was conducted over 18 months (2 months pre- and 16 months post-intervention) in all women admitted for eLSCS in our institution. Interventions included eLSCS surgical prophylaxis guideline dissemination and post-eLSCS oral antibiotics was actively discouraged in those without SSI risk factors. This was followed by ASP intervention notes (phase 1) for 3 months, contacting the ward team for the next 7 months (phase 2) and subsequently the primary obstetrics attending in Phase 3 (next 6 months). The primary outcome was post-operative oral antibiotics prescription rates, and secondary outcomes included 30-day post-operative SSI rates. Results A total of 1751 women was reviewed. Appropriateness of pre-operative antibiotic prophylaxis was 99%. There were 244 (13.9%) women pre-intervention and 1507 (86.1%) post-intervention. Post-eLSCS antibiotic prescribing rates reduced significantly post-intervention (200, 82% vs 705, 46.8%, p < 0.001). There was no significant difference in SSI rates pre-post intervention (2, 0.8% vs 28, 1.9%, p = 0.420). There was also no significant difference in SSI rates among those who received post-operative oral antibiotics compared to those without (1.9%, 17 of 905 vs 1.5%, 13 of 846, p = 0.582). Conclusions ASP interventions can reduce unnecessary post-eLSCS antibiotic prophylaxis use without adversely impacting patient safety. |
