Rate and risk factors of surgical site infections with antibiotic prophylaxis.
OBJECTIVE
This study is aimed at determining the incidence of surgical site infections, with antibiotic use. Furthermore, to correlate infection with type of operations, length of intervention, number of stitches, pre-operative hospitalization, age and sex of the patient.


METHODS
All Yemeni patients (N=601) who underwent surgical intervention, with preoperative antibiotic prophylaxis, at Al-Kuwait University Hospital, Sana'a, Republic of Yemen, during 1st August 2000 through to 30th November 2000 were followed up until stitch removal or discharge. Data was registered in a spreadsheet and processed statistically by statistical package for social sciences 10.0.


RESULTS
Overall incidence of surgical site infections was 2.2%, 0.5% in clean operation, 2.8% in clean contaminated, 9.1% in contaminated and 2.3% in dirty operations. Surgical site infections were found positively correlated with duration of operation (P=0.015) and number of stitches (P=0.017), but insignificantly associated with sex, age, type of operation and pre-operative hospitalization.


CONCLUSIONS
In conclusion, surgical site infections, with antibiotic use, were found low. Higher number of stitches and longer duration of operation were the risk factors.
