Surveillance of Surgical Site Infections: A Public Health Emergency in a Regional Hospital of Northern Benin. A Prospective Observational Pilot Study

Background: Surgical site infections (SSIs) are considered as result of the healthcare quality in hospitals.Objective: to study SSI at Saint Jean de Dieu Hospital Tanguieta (SJDHT), prior to the implementation of a permanent monitoring system.Method: transversal, and descriptive study with prospective data collection was performed from 1 July to 31 janvier 2017 in the department of general surgery of SJDHT.The hospital lacks in a microbiology unit.All patients who underwent surgery during this period were included and the monitoring lasted one month.SSIs diagnostic was carried out according to WHO criteria as described in the Practical Guide for the Prevention of Nosocomial Infections published in 2002.Statistical tests (χ-square and Student's t-test) were applied and p < 0.05 were statistically significant.Results: Of 343 patients recorded, 105 (30.6%) had SSI.Their age averaged 40.3 years and the sex-ratio (men/women) was 2.8.The emergency surgery resulted in a 50.0%rate of SSI (p = 0.00).The SSI rate for clean and clean-contaminated surgery was 6.3% against 94.6% for infected surgery (p = 0.00).The SSI rates were 100% and 66.7% for NNISS = 2 and NNISS = 1 (p = 0.00), respectively.Superficial SSI rate was 13.3%, while deep SSI and organ/space SSI were 46.7%
