WTP7.12 Investigating the duration of empirical antibiotic treatment and subsequent reduction in hospital readmission rates for perforated appendicitis in the paediatric patient population
British Journal of Surgery(2023)
Abstract
Abstract Background and Aim Acute appendicitis is the most common surgical emergency in the paediatrics. Complicated appendicitis often involves perforation, requiring a longer course of antibiotics post-appendicectomy [1]. There is considerable variability on post-operative antibiotic regimes and duration within hospital trusts with no national guidelines. Local Trust-based consensus [2] recommends a 5-day course IV co-amoxiclav with American Paediatric Surgical Association guidelines suggesting oral conversion if IV antibiotic duration is less than 5 days [3, 4]. Therefore, we measured compliance with local and international guidelines. Methods Paediatric patients aged 5-17 years were selected for the study using ICD-10 codes for ‘Perforated Appendicitis’ (K35.2 and K35.3). Patients were included if they had operative management for perforated appendicitis between 1 April 2021 and 31 March 2022. Key parameters collated included; re-admission, duration of re-admission, complication, post-operative antibiotic use (selection, intravenous/oral dose and duration of use). Results Twenty-six paediatric appendicectomies for perforated appendicitis occurred within the time frame. Nine had IV antibiotics for >5 days, of this cohort, 7 had oral conversion and completed 2-5 days of oral antibiotics with re-admission rate 33%. Eleven had IV antibiotics for < 5 days with oral conversion for 4-7 days, readmission rate was 18.2% on days 4 & 5 respectively. Six had IV antibiotics for <5 days with no oral conversion and no patients were re-admitted. Conclusions A longer duration of antibiotics with an earlier conversion from IV to oral, reduced readmission rates. However, greater research with more participants and standardised antibiotics can explore other influencing factors.
