Endocarditis infecciosa asociada al cuidado de la salud. Estudio de prevalencia en un hospital de alta complejidad

Introduction: Invasive procedures the vascular tract cause health, are related to blood stream infections, among them, infective endocarditis. This adverse event leads to greater morbidity and mortality compared with community acquired infective endocarditis. Objective: To evaluate the prevalence of healthcare-associated infective endocarditis, describe the demographic characteristics of this population and the etiological agents. Method: Cross-sectional descriptive, prevalence study of prevalence. It included patients ≥18 years old with healthcare-associated infective endocarditis, documented at Fundación Cardioinfantil. Statistical analysis with distribution of variables of age, gender, invasive procedure associated and isolated microorganism was made. Results: 41 patients were obtained. The average age was 60.6 years. There was no distinction between men (22, 53.6%) and women (19, 46.3%). The patients were grouped according to the procedure performed in: implantation of high-flow intravascular devices (16, 39.02%), central venous catheter (12, 29.26%) and intracardiac devices (11, 26.82%). The general prevalence in the evaluated procedures was 0.21%, being 1.42% in high-flow intravascular devices, 0.72% in intracardiac devices and 0.08% in central catheters. The registered mortality was 4,9% (2 patients). In 78.05% of the patients, microbiological isolation was obtained. Conclusions: patients who has invasive procedures may have an incremented risk of infective endocarditis because of the procedure. The low intrahospital mortality could be related with the remarkable number of microbiological identification which facilitated a directed antimicrobial therapy.
