According to estimates by the National Audit Office (NAO) hospital acquired infections (HAl), in particular surgical site infections (SSls), cost the NHS on average 3200 pounds per SSI and cause a mortality rate of at least five thousand patients a year (Leaper 2010). Despite practitioners' knowledge of safe working technique and control of infection, reported cases of nosocomial infections are still high, despite a reduction in-rate from 9% in 1993/4 to 8.2% in 2006 (Roberts & Cookson 2009).
根据国家审计署（NAO）的估计，医院获得性感染（HAI），尤其是手术部位感染（SSI），平均每例SSI给英国国民医疗服务体系（NHS）造成3200英镑的损失，每年导致至少5000名患者死亡（利珀，2010年）。尽管从业者了解安全工作技术和感染控制，但医院感染的报告病例仍然居高不下，尽管感染率从1993/1994年的9%降至2006年的8.2%（罗伯茨和库克森，2009年）。
