POSA113 The Cost Analysis of the Environmental Impacts of Surgical Site Infection from the Perspective of NHS England

Surgical site infection (SSI) remains a common complication of surgical procedures. SSI leads to significant burden in terms patient morbidity and healthcare resource use (HRU). The environmental impact treating its associated cost has not been evaluated. This study aims analyse the HRU for NHS England. A budget model was created from perspective incidence rates were sourced Public Health England literature. Environmental sustainability data obtained Sustainable Care Pathways Guidance UK government greenhouse gas (GHG) emissions valuation guidance, water supplier waste management report undertaken by Royal College Nursing UK. Outcomes assessed total costs, GHG emissions, direct generation due additional hospital stay, outpatient appointments A&E visits. Deterministic probabilistic sensitivity analyses (DSA PSA) conducted. It estimated that 39,746 cases occur yearly hospitals Patients with longer length stays (LOS; +10 days), 4.1 more 22% visits compared patients without SSI. Annually, these activities is 22,997 tonnes CO₂e, 35 million m³ (0.2 use) 2,643 waste. annual ₤2,667,527. In DSA, results most sensitive per unit LOS According PSA, mean (95% CrI) ₤2,670,487 (₤2,151,365 - ₤3,193,724). prevention could lead benefits further reduce costs
