Abstract
Background: Appropriateness of antibiotics use involves determining the need, and timing of
adequate antibiotics in indication and dose, which measured by content and quality of prescribing
decisions for the individual patient. Usually prescribers expected to be prescribing appropriately,
but clinical decisions to initiate and choosing properly may be challenging, especially in
developing countries where poor diagnostic test and availability.
Objective: This was to asses’ appropriateness of antibiotics use and associated factors in the
hospitalized patients.
Methods: Hospital based prospective follow up study was conducted in Internal medicine ward
(IMW), at UGSH. Data was collected by chart review and prescriber interview using a pretested
questionnaire derived from RAND modified Delphi method. The data was assessed, cleaned,
entered to Epi info 7 and analyzed using SPSS, version 20. Descriptive statistics and Binary
logistic regression was applied to show the association.
Result: The mean age of patients were 44.36+1.07 years. About 57.1% patients were females.
The appropriate antibiotics use was low 26 (8.6%). Male patients were 5.9 times more
appropriate than females patients (AOR 95% CI 5.90(1.43-24.28), p<0.02). Merchant patients
had received antibiotics 13 times more appropriate than students and daily labor patients
12.98(AOR 95% CI 1.34-125.40). Specimens of blood 23.81 times and cerebrospinal fluid 23.75
times more appropriate than patients received without any specimen for confirmation of
diagnosis 23.81(4.68-121.07) and 23.75(5.60-100.74) respectively. Prescribing antibiotics
according to the national guideline increases 4.34 times appropriate than patients receiving
antibiotics according to IDSA guideline and expert opinion.
Conclusion: The appropriateness of antibiotics use was very low. Male patients used antibiotics
more appropriately than females. A patient with specimen for culture or gram stain had
significantly increased use of appropriate antibiotics. Patients work as a merchants and with free
medical service had more appropriate antibiotics use. Prescribing antibiotics according to the
national guideline increased the coverage of likely pathogens and appropriateness of antibiotics.
