ABSTRACT
Nosocomiol infection incidence and its cost were studied. We have identified 61 infected patients and 75 infectious episodes, is an incidence of 9,4% infected for 100 hospitalized by trimester. Operative site infections are the most frequent [60%], operative site infection [9,1%], inferior respiratory ways infections [2,2%]. Incriminated germs are represented essentially by negative gram Bacillus [77,3%] with predominance of enterobacterias [59%]. Invasive technique usage, surgery types and contamination classes have been identified as risk factors of nosocomial infection occurrence. The supplementary stay duration estimated by simple comparison between infected group and non-infected one is 9,3% days, responsible of an over cost of 336 TD by infected patient and 273 TD by infectious episode. The curative antibiotic costs have been estimated at 70 TD by infected patient being equivalent to two hospitalization days and to 57 TD by infectious episode
