Impact of an educational intervention on WHO surgical safety checklist and pre-operative antibiotic use at a referral hospital in southwestern Uganda

Introduction: The World Health Organization (WHO) recommends adherence to its surgical safety checklist (SSC) to optimize patient safety and reduce cesarean surgical site infection (SSI). Educational interventions combined with audit and feedback mechanisms on the checklist use by clinicians have the potential to improve adherence and clinical outcomes. Despite the increase in cesarean delivery rates, there is a paucity of data on how such interventions can improve adherence in resource-limited settings.Objective: We performed a quality improvement project to measure the impact of an educational intervention with daily audit and feedback procedures on rates of WHO SSC adherence, including pre-operative antibiotic administration and SSI at Mbarara Regional Referral Hospital maternity ward in Uganda.Methods: The study involved chart abstraction of WHO SSC and pre-operative antibiotic use during cesarean deliveries and signs of subsequent SSI in three phases. First, we conducted a retrospective review of all charts from May to June 2018 (pre-intervention phase). Second, we instituted an educational intervention on the WHO SSC and pre-operative antibiotics use, followed by a daily audit of charts and feedback to clinicians from July to August 2018 (the intervention phase). Third, we reviewed charts from September to October 2018 (the post-intervention phase). The WHO SSC adherence, pre-operative antibiotic administration and SSI rates were measured as the proportion of the total cesarean deliveries per study phase and then compared across the three phases.Results: We reviewed 678 patients' charts (200 in the pre-intervention phase, 230 in the intervention phase and 248 in the post-intervention phase). The mean patient age was 25 years. The use of the WHO SSC was 7% in the pre-intervention phase compared to 92% in the intervention phase (P < 0.001), and 77% in the post-intervention phase (P < 0.001). Pre-intervention antibiotic receipt was 18% compared to 90% in the intervention phase (P < 0.001) and 84% in the post-intervention phase (P < 0.001). The documented SSI rate in the pre-intervention phase was 15% compared to 7% in the intervention phase (P = 0.02) and 11% in the post-intervention phase (P = 0.20).Conclusions: An educational intervention, daily audit and feedback to clinicians increased the use of the WHO SSC and prophylactic antibiotics for cesarean delivery-although the rates waned with time. Research to understand factors influencing the checklist use and antibiotic prophylaxis including prescriber knowledge, motivation and clinical process is required. Implementation interventions to sustain usage and impact on clinical outcomes need to be explored.
