[Incidence of surgical wound infections a prospective study in the Rabat Mohamed-V military hospital, Morocco]. / Incidence des infections du site opératoire étude prospective à l'hôpital militaire d'instruction Mohamed-V de Rabat, Maroc.

ABSTRACT

OBJECTIVES: The authors had for aim to determine prospectively the incidence of surgical site infections (SSI) in a visceral surgery department, in the Mohamed V military hospital (Rabat), and to identify risk factors. PATIENTS AND METHODS: All patients who had undergone surgery between April 1 and September 30, 2002 and were then admitted in the visceral surgery unit were included in this study. Patients were assessed within the following month. For each patient, data including perioperative factors, type of procedure, and SSI occurrence were collected on a standardized form. RESULTS: During the study, 310 patients were operated. The number of surgical wound infections was 16 (5.2%). This analysis pointed out 11 superficial wounds, 5 deep wounds, and 1 organ/site wound. Emergency, age, ASA score, Altemeier classification, and procedure duration were found to be risk factors for SSI in visceral surgery. According to the NNIS index, SSI rates increase from 2.7% for patients with a risk index of 0 to 10.2% for patients with a risk index of 3. CONCLUSION: The high incidence of SSI emphasizes the importance of implementing SSI surveillance in surgery to obtain standardized incidence ratios necessary for adapted control measures.
