Summary

Being labelled as allergic to penicillin has been associated with an increase in the risk of infection after surgery in a number of studies in USA, Canada and France. This is thought to be due to the use of inferior antibiotic regimens for preventing infection at the time of surgery. We studied a large cohort of patients that had undergone gastrointestinal surgery at Addenbrooke’s Hospital to see if this observation could be generalised to a UK population, where the range of preventative antibiotic regimens in routine use differs significantly. We found no evidence of association between penicillin allergy labels and likelihood of surgical site infection in this cohort, suggesting significant international variation in the impact of penicillin allergy labels on patients.
