Estudio de prevalencia de infecciones nosocomiales en una unidad médica de alta especialidad

Abstract

Objective: The purpose of this research was to analyze the intIntroduction: Within third level medical attention units; there are factors which lead to a higher frequency of Hospital Infections (HI). Because of this; it is fundamental to assess periodically the epidemiologic surveillance systems sensibilities in order to verify their functionalities as well as the objective achievements. Objective: To assess the prevalence of HI in one high Specialty Medical Units; as an indicator of the actions taken by the Hospital Epidemiologic Surveillance Unit (HESU);and also to assess the risk factors associated with the prevalence of HI. Methodology: Basic observational study with a population of 383 hospitalized patients. Results: We found that 73.9% had invasive processes. We identified 68 cases with Hospital Infection (17.8).The most frequent HI were general bacterial invasions (38.2%) and pneumonias (20.6%).The most frequently identified microorganisms were pseudomona sp; enterobacter aglomerans; serratia marcescens; staphylococcus aureus; and Escherichia coli. Besides to be newborn and nursing other factors associated to IN bt RM they were inmunocomprometed to be; having venous catheter by dissection; peritoneal intubation; mechanical ventilation; parenteral nutrition and having a contaminated surgery; factors that are significantly (p = 0.05) to the risk of IN. Conclusions: This study allowed us assesses and characterize the prevalence of HI as an indicator of the HESU functionality in order to establish infection control measurements.
