Abstract
Although breast surgery involving clean wounds is expected to be associated with a low risk of surgi-cal site infection (SSI) and minimal associated costs, estimates of infection could be affected by intensity of case finding and choice of follow-up methods. A broad range of post-discharge follow-up methods is more likely to estimate true SSI rates and costs. This prospective systematic study used 30 day surveillance with active data collection methods to identify the rate and cost of surgical site infection in patients having primary breast surgery. Ten per cent of patients (16/159) had a surgical site infection. The additional average cost of treating each infected patient was £1443. Hierarchical sequential regression identified high body mass index, operations lasting more than two hours and smoking as significant independent risk factors.
