Résumé
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.

A prospective survey of antibiotic use in 5 departments (MED, SURG, OB-GYN, PED, ORTHO) in Srinagarind Hospital was done during May 1988. The majority of prescribers were interns and residents, except in the department of OB-GYN. Out of 400 prescriptions, 52.3 per cent were inappropriate and 5 per cent were inappropriate for economic reasons. For empirical use, the inappropriateness was 42.3 per cent mostly due to no indication of use. For surgical prophylaxis, 82.4 per cent were inappropriate mostly due to delayed prophylaxis and excessive length of treatment of more than 72 hours. For the treatment of documented infection, 39.6 per cent were inappropriate, mostly due to wrong choice and too many drugs used. There were no statistical differences in mortality, total hospital stay, hospital stay after treatment between the appropriate and inappropriate use.
