Application of ATC/DDD methodology to evaluate perioperative antimicrobial prophylaxis.
OBJECTIVE
To evaluate quality of perioperative antibiotic prophylaxis (PAP) and to calculate the cost per procedure in a Turkish university hospital.


METHODS
A 352-bed teaching hospital in Denizli, Turkey.


METHODS
An prospective audit was performed between July and October 2010. All clean, clean-contaminated and contaminated elective surgical procedures in ten surgical wards were recorded. Antimicrobial use was calculated per procedure using the ATC-DDD system. The appropriateness of antibiotic use for each procedure was evaluated according to international guidelines on PAP. In addition, the cost per procedure was calculated.


RESULTS
Overall, in 577 of the 625 (92.3%) of the studied procedures, PAP was used. PAP was indicated in 12.5% of the group where it was not used, and not indicated in 7.1% of the group where it was used. Unnecessarily prolonged antimicrobial prophylaxis was observed in 56.9% of the procedures, mean duration was 2.6 ± 2.7 days. The most frequently used antimicrobials were cefazolin (117.9 DDD/100-operation) and sulbactam/ampicillin (102.2 DDD/100-operation). The timing of the starting dose was appropriate in 545 procedures (94.5%). In the group that received PAP, only 80 (13.7%) of the procedures were found to be fully appropriate and correct. The density of antimicrobial use per operation was 2.8 DDD. The mean cost of the use of prophylactic antimicrobials <euro>18.6 per procedure.


CONCLUSIONS
The density of antimicrobial use in PAP was found to be very high in our hospital. Antibiotic overuse extended into the postoperative period.
