Removal of Erroneous Penicillin Allergy Labels: Implementation Study (REPeAL)

Aim: To test implementation of the penicillin allergy de-labelling complex intervention in surgical, medical and critical care patient pathway. Objectives: * To use the Institute for Health Improvement (IHI) Model for Improvement methodology to implement the penicillin allergy de-labelling complex intervention in each setting (surgery, medicine, critical care) * To measure the number of patients meeting inclusion criteria (\>16 with a penA not prescribed first line antibiotics) who have had their penicillin allergy record assessed by the wider clinical teams and separately by the AMS team. * To measure the patient uptake of penicillin allergy record removal (i.e. the rate of patient declining de-label / DOC). To interview 10-15 patients and 10-15 healthcare workers to gain insight into the penicillin allergy de labelling process.
