Intervention of inappropriate antibiotic use at a university teaching hospital

Abstract

The magnitude of inappropriate antibiotic use is high (52.3%). In the empiric treatment group, 41.1 per cent were inappropriate, mostly due to no indication of use. In the surgical prophylaxis, 79.7 per cent were inappropriate, mostly due to delayed prophylaxis and length more than 3 days. In documented infection, 40.2 per cent were inappropriate, mostly due to wrong choice and too many drugs. Intervention by education decreased the overall inappropriate use, empiric inappropriate use and prophylactic use, while there was no change in inappropriate documented infection use and inappropriate economic use. We propose further interventions by other strategies, repeated education and a wider scale of intervention.
