Comportamiento epidemiológico de las tasas de infecciones asociadas a la atención en salud en la Unidad de Recién Nacidos del Hospital Universitario San Ignacio desde enero de 2011 hasta diciembre de 2020

Objective: to describe the incidence rates of healthcare associated infections related to devices, presented in the newborn unit of a university hospital in the city of Bogotá, Colombia. Materials and methods: descriptive observational cross-sectional study period. 83 patients with 84 healthcare-associated infections related with devices hospita-lized at the San Ignacio University Hospital from 2011 to 2020 were included. Results: 59.3% of the patients (n=50) were preterm, and 61.9% were male (n=52). The most common healthcare associated infection was catheter-associated bloodstream infection (89.2%; n=75) with an incidence rate of 1,5 to 6,3 per 1000 catheter days, with Staphylococcus epidermidis being the most common microorganism ( 78.7%). Ventilator-associated pneumonia caused by methicillin-resistant Staphylococcus Aureus (50%) with an incidence rate of 5,3 to 6,3 per 1000 days on the ventilator, ranked second, and catheter-associated urinary tract infection with a rate of incidence from 1,5 to 9,5 per 1000 catheter days, was the third in frequency. Discussion: neonatal unit incidence rates are comparable to national incidence rates, below those reported by the INICC and above those reported by the NHSN. Prevention strategies are a tool to reduce incidence rates.Conclusion: the incidence rates of device-related HAIs were higher in preterm newborns, and prevention strategies are a challenge to reduce associated morbidity and mortality.
