Determinants of invasive ventilator-associated pneumonia in an intensive care unit of a central hospital ; Determinantes de la neumonía asociada a la ventilación invasiva en una unidad de cuidados intensivos de un hospital central ; Determinantes da pneumonia associada à ventilação invasiva numa unidade de cuidados intensivos de um hospital central

Background: Healthcare-associated infections are a prevalent issue in health systems that affect everyone. The incidence and prevalence of healthcare-associated infections depend on the context in which they occur. An example of this is ventilator-associated pneumonia in intensive care units. Objective: To analyze the determinants of ventilator-associated pneumonia in an intensive care unit of a central hospital in northern Portugal. Methodology: A retrospective, descriptive-correlational quantitative study was conducted with 705 patients admitted to the ICU of the hospital under investigation. Results: The results show that male gender, previous antibiotic use, endotracheal reintubation, level of consciousness, cuff pressure, ventilation time, injury, poisoning, and certain other consequences of external causes as admitting diagnosis are among the determinants of ventilator-associated pneumonia. Moreover, the incidence of ventilator-associated pneumonia was of 4.5%. Conclusion: The study recommends the judicious use of antibiotics, limiting the duration of invasive ventilation, implementing ventilator weaning protocols, and auditing compliance with the care bundle for ventilator-associated pneumonia. This study sheds light on the prevention of ventilator-associated pneumonia and its recommendations contribute to better care and more effective and safer nursing interventions. ; Marco contextual: Las infecciones asociadas a los cuidados sanitarios (IACS) son un problema actual en los sistemas sanitarios, y su incidencia y prevalencia varían en función del entorno asistencial. Un ejemplo de ello es la neumonía asociada a la ventilación mecánica (PAV), que se da en las unidades de cuidados intensivos (UCI). Objetivo: Analizar los determinantes de la PAV en pacientes ingresados en la UCI de un hospital central del norte de Portugal. Metodología: Estudio descriptivo-correlacional y retrospectivo, basado en los registros de 705 pacientes ingresados en la UCI. Resultados: Los factores determinantes de la PAV fueron el ...
