Introduction: our study was conducted, in university hospital center (UHC) Farhat Hached of Sousse (city in Tunisian center-east), within healthcare-associated infections (HAI) epidemiological surveillance (ES) program,  based, among others, on HAI regular prevalence surveys. Our objectives are to resituate HAI prevalence rate and to identify their risk factors (RF) in order to adjust, in our hospital, prevention programs.

Methods: it is a transversal descriptive study, including all patients who had been hospitalized for at least 48 hours, measuring prevalence of HAI a “given day”, with only one passage by service. Risk factors were  determined using Epiinfo 6.0, by uni-varied analysis, then, logistic  regression stepwise descending for the variables whose p

Results: the study focused on 312 patients. Infected patients prevalence was 12.5% and that of HAI was 14.5 %. Infections on peripheral venous catheter (PVC)  dominated (42.2%) among all HAI identified. HAI significant RF were neutropenia (p<10-4) for intrinsic factors, and PVC for extrinsic factors (p=0,003).

Conclusion: predominance of infections on PVC should be subject of specific prevention actions, including retro-information strategy, prospective ES, professional practices evaluation and finally training and increasing awareness of health personnel with hygiene measures. Finally,  development of a patient safety culture with personnel ensures best adherence to hygiene measures and HAI prevention.
