Abstract
IntroductionOur 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.MethodsIt 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 pResultsThe 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).ConclusionPredominance 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.
Highlights
Healthcare-associated infections (HAI) represent a universal public health problem due to their frequency, their seriousness and their additional cost
We have carried out our study, in 2012, at university hospital centre (UHC) Farhat Hached of Sousse, according to HAI Epidemiological surveillance (ES) program based on regular prevalence surveys that have started since 2000 in order to better direct prevention axes
As for invasive care exposure, our study showed that peripheral venous catheter (PVC) exposure frequency was significantly higher in infected patients (Table 2)
Summary
Healthcare-associated infections (HAI) represent a universal public health problem due to their frequency, their seriousness and their additional cost. They increase hospital stay and engender morbidity and mortality with heavy economic and legal burden, everywhere in the world. Epidemiological surveillance (ES) represents a central axe in any HAI prevention strategy. There are different methods of ES, especially prevalence surveys which constitute one of the most common methods adopted, in most countries, allowing follow of HAI’ frequency and epidemiological particularities’ evolution [3]. We have carried out our study, in 2012, at university hospital centre (UHC) Farhat Hached of Sousse, according to HAI ES program based on regular prevalence surveys that have started since 2000 in order to better direct prevention axes.
