Antibiotic prescribing patterns for management of acute diarrheal diseases at a university teaching hospital in Central Ethiopia

Abstract

BACKGROUND: Antibiotic resistance has emerged largely due to the improper use of antibiotics in clinical practice, although most acute diarrheal diseases resolve without antibiotic treatment and should be reserved for cases of invasive bacterial or dysenteric diarrhea. This study aimed to assess the patterns of antibiotic use for acute diarrheal diseases at Nigist Elleni Mohammed Memorial Teaching Hospital (NEMMTH) in Central Ethiopia. METHODS: A retrospective cross-sectional study was conducted to assess patients treated for diarrhea between January 1 and June 30, 2023. The appropriateness of antibiotic prescriptions for diarrhea was evaluated according to the Ethiopian Standard Treatment Guidelines. Data were collected using a structured abstraction form, and patient charts were selected through systematic random sampling. The analysis was performed using the Statistical Package for Social Sciences version 25. RESULTS: Among 302 patients evaluated, 53.3% were female and 46.4% were children under five years old. Of the 302 patients, 57.6% had watery diarrhea. A total of 74.5% of patients received at least one antibiotic, of whom 73.5% received a single antibiotic during the treatment of acute diarrheal cases. The most commonly prescribed antibiotics were metronidazole (18.2%), cotrimoxazole (17.5%), and ciprofloxacin (11.6%). The proportion of inappropriate antibiotic prescribing was 77.1%. CONCLUSIONS: This study found a high level of inappropriate antibiotic use for acute diarrheal disease at NEMMTH. Metronidazole and cotrimoxazole are the most commonly prescribed antibiotics. Ensuring proper management by adhering to the standard treatment guidelines is crucial.
