The purpose of this study is to evaluate in a multicentric cluster randomized study the effect of the presence of dedicated nurses for training of ICU staff in preventing nosocomial infections. The rate of bloodstream infections per 100 admitted patients is used as the main endpoint. A sample of 4000 included patients in the 6 participating ICU is included with the objective to show a reduction of one third of the rate of ICU-acquired bloodstream infections. The study is currently at the end of the recrutimeent phase.

15% of patients admitted to intensive care have an infection acquired in the service, including bacteremia is a serious form. Compliance with hygiene measures and recommendations in the use of invasive devices can reduce the incidence. The advantage of simple recommendations type "bundle" could, however, be insufficient because not associated with training and monitoring compliance with the recommendations. The aim of this study is to show that the daily intervention of a public health nurse on the basis of a half full-time equivalent, allows these actions and therefore a reduction in the bloodstream of the attack rate acquired in the ICU compared dissemination of simple recommendations.
