1193 Review of Pre-Operative Antibiotic Prophylaxis (POAP) in National Emergency Laparotomy Audit (NELA) Patients in a Regional Acute Tertiary Hospital

Abstract

Abstract Aim The current World Health Organization recommendation for timing before incision (TBI) is that one dose of intravenous pre-operative antibiotic prophylaxis (POAP) should be given on starting anaesthesia, within 120 minutes, to reduce surgical site infections. The Scottish Intercollegiate Guidelines Network suggests TBI of 30-60 minutes for full dosage administration. The aim was to review POAP, including TBI, in NELA patients. Method Emergency laparotomy patients were identified on the Trust theatre system over 73 days, and the NELA database reviewed. Data was collected retrospectively through anaesthetic and operation records and if still inpatient, drug charts and clinical notes. Results 46 patients were identified, and 83% had documented POAP (53% on anaesthetic record, 31% on operation note and 16% before surgery). Of these patients who had a documented POAP, 68% had a recorded TBI; mean time was 99 minutes (range 19 to 386). Of the patients who had a recorded TBI, 77% received POAP within 120 minutes; mean time of these was 59 minutes (range 19 to 112). Conclusions The majority of patients received pre-operative antibiotic prophylaxis, although the documentation was variable, and many doses were not given in the optimal time before incision to reduce surgical site infections. Further work includes liaising with the multidisciplinary team to raise awareness of these results and amending the clerking proforma. A further subgroup analysis focusing on septic patients is underway, as well as a long-term review looking into surgical site infection rates.
