Comparison of respiratory infections before and after percutaneous tracheostomy

Am J Crit Care. 2014 Nov;23(6):e80-7. doi: 10.4037/ajcc2014232.

Abstract

Background: A tracheostomy is often performed when patients cannot be weaned from mechanical ventilation. Respiratory infections (ventilator-associated pneumonia and infection of the lower respiratory tract) complicate the course of hospitalization in patients receiving mechanical ventilation.

Objectives: To evaluate respiratory infections before and after a percutaneous tracheostomy and to describe their outcomes.

Methods: Medical records of adults who had percutaneous tracheostomy during a 1-year period at a tertiary care hospital in the southeastern United States were reviewed retrospectively.

Results: Data for 322 patients were analyzed. Patients were predominately male (63.0%) and white (57.8%), with a mean age of 57.4 years. Ventilator-associated pneumonia or infection of the lower respiratory tract was identified in 90 patients (28.0%); the majority of infections were lower respiratory infections. Of all infections, 52% occurred before the tracheostomy, and 48% occurred after the procedure. Respiratory infections were associated with longer stays and higher costs, which were significantly higher in patients in whom the infection developed after the tracheostomy. Gram-negative organisms were responsible for the majority of infections.

Conclusions: Data related to respiratory infections that occurred before a tracheostomy were similar to data related to infections that occurred after a tracheostomy. Most infections were classified as lower respiratory infection rather than pneumonia. Infection, before or after a tracheostomy, resulted in longer stays and higher costs for care. Interventions focused on preventing infection before and after tracheostomy are warranted.
