Chouchene, I., Bouafia, N., Ben Cheikh, A., Toumi, B., Mahjoub, M., Bannour, W., Helali, R., Njah, M. and Bouchoucha, S. (2015) Incidence of device-associated infections in a Tunisian intensive care unit. Sante Publique. 27(1), p.69-78. .
INTRODUCTION: Healthcare-associated infections represent a real public health problem. They are particularly frequent and severe in intensive care units due to the serious diseases presented by patients and the almost systematic use ofvarious medical devices. A study of the incidence of device-associated infections was conducted in the ICU of CHU Farhat Hached Sousse (Tunisia) to estimate the incidence and to identify risk factors for DAI.
METHODS: This prospective incidence study was conducted during the first quarter of 2012, with anonymous and standardized data collection for all patients hospitalized for at least 48 hours.
RESULTS: Out of a total of 105 patients hospitalizedfor more than 48 hours during the study period, 17 cases of DAI were identified. The incidence density was 16.9 infected patients / 1,000 days of hospitalization. The infections most frequently identified were central and peripheral venous catheter-associated infections. Independent riskfactorsfor DAI in the ICUwere length of ICU stays which increased the risk of DAI by 1.10 per day (95% CI [1.03 – 1.17]; p=0.002), and the use of CVC, which increased the risk by 3.29 (95% CI [1.36 – 7.95]; p=0.031).
CONCLUSION: The implementation of continuous surveillance of healthcare-associated infection in the intensive care unit should be encouraged in order to guide the actions of prevention and control of nosocomial infection risk.
