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