[Long-term usefulness of an information programme on practices in surgical antimicrobial prophylaxis].

INTRODUCTION
In France, numerous concordant studies show that there are some discrepancies between guidelines on surgical antibiotic prophylaxis and the current practice. In a previous study, conducted in April-June 2001, we found that the rate of appropriateness of surgical antimicrobial prophylaxis was approximately 40%. An information programme was implemented and the purpose of this paper was to present the short- and long-term usefulness of this campaign.


METHODS
A total of 13 pairs of surgeons/anaesthetists participated in data collection during the three periods of the study. Prescriptions were observed in order to answer to five questions. Five variables describing practices concerning antibiotic prophylaxis in surgery were compared to national recommendations (updated in 1999): did the surgical procedure require antibiotic prophylaxis and was this carried out? Was the antibiotic used appropriate? Was the timing of the first injection optimal? Was the total duration of the treatment correct? Was the dose correct?


RESULTS
The overall compliance with recommendations was significantly improved during the third period (P = 0.0002). This improvement was particularly marked for antimicrobial prophylaxis duration.


CONCLUSION
It seems that sequential surveillance of antimicrobial prophylaxis, including numerous surgical teams, could considerably improve the practices, if it was associated to informations that allowed physicians to appropriate the procedures.
