Impact of Tracheostomy Timing Within the National Veterans Affairs Population.

Abstract

There is a lack of a definitive study in the literature comparing early versus late tracheostomy and exploring the impact of tracheostomy timing on patient outcomes. This study may help guide treatment paradigms and contribute to a consensus for optimal tracheostomy timing. A retrospective review was performed comparing early versus late timing of tracheostomy placement and their respective outcomes. The authors used data provided by VA Informatics and Computing Infrastructure (VINCI) to find patients who received a tracheostomy at any VA Medical Center in the United States. There were a total of 25,334 tracheostomies in the database which satisfied our criteria. These occurred between the years 1999 and 2022. Propensity score matching assessed 17,074 tracheostomies, 8537 in either group. The median age of patients in the matched groups was 66 years, and approximately 97.4% of patients were male. Early tracheostomy timing was defined as the placement of the tracheostomy within 10 days of intubation. Outcomes included post-tracheostomy intensive care unit (ICU) days, post-tracheostomy hospital days, successful ventilator weaning, and all-cause mortality. Early tracheostomy was associated with significantly fewer ICU days and hospital days, and the early group experienced higher rates of successful ventilator weaning. Survival analysis of data within 5 years of tracheostomy showed that early tracheostomy was associated with significantly lower hazard for all-cause mortality. Our results add to the body of evidence that an earlier transition to mechanical ventilation by tracheostomy confers benefits in patient morbidity and mortality as well as resource utilization. 3 Laryngoscope, 2024.
