Epidemiological Surveillance of Healthcare-associated Infections
Keywords:
Cross infection, Sepsis, Health centers.Abstract
Introduction: epidemiological surveillance is useful for identifying the risk of acquiring in hospitals a healthcare-associated infection and other related risk factors.
Objective: show the results of epidemiological surveillance of infections in Abel Santamaría Cuadrado General Hospital of Pinar del Río Province.
Material and method: An observational, descriptive, prospective study. The study group was composed of the 25 786 patients discharged in 2012 and the sample, by the 578 patients who acquired an infection associated to healthcare. The following variables were used: service of origin, location of infection, isolated organism and death. The information was obtained by reviewing medical, microbiology and pathological anatomy records and death certificates.
Results: a generalized infection rate of 2.2 per 100 discharges from service was obtained. 47.5% of patients with infections had a respiratory condition. Enterobacteria were germs isolated the most, predominantly including E. coli and Enterobacter. The risk of dying from healthcare-associated infections was 4 per 1000 hospital discharges with a fatality rate of 20.1%.
Conclusions: epidemiological surveillance was effective for identifying healthcare-associated infections with an adequate rate of hospital incidence, being more frequent respiratory infections, especially Enterobacteriaceae, with mortality and lethality suitable for this type of hospital.
