Impact of Early Tracheostomy on Outcomes After Cardiac Surgery: A National Analysis.

ABSTRACT

BACKGROUND: Despite evidence supporting its early use in respiratory failure, tracheostomy is often delayed in cardiac surgical patients given concerns for sternal infection. This study assessed national trends in tracheostomy creation among cardiac patients and evaluated the impact of timing to tracheostomy on postoperative outcomes. METHODS: We used the 2005 to 2015 National Inpatient Sample to identify adults undergoing coronary revascularization or valve operations and categorized them based on timing of tracheostomy early tracheostomy (ET) (postoperative days 1-14) and delayed tracheostomy (DT) (postoperative days 15-30). Temporal trends in the timing of tracheostomy were analyzed, and multivariable models were created to compare outcomes. RESULTS: An estimated 33,765 patients (1.4%) required a tracheostomy after cardiac operations. Time to tracheostomy decreased from 14.8 days in 2005 to 13.9 days in 2015, sternal infections decreased from 10.2% to 2.9%, and in-hospital death also decreased from 23.3% to 15.9% over the study period (all P for trend <.005). On univariate analysis, the ET cohort had a lower rate of sternal infection (5.2% vs 7.8%, P < .001), in-hospital death (16.7% vs 22.9%, P < .001), and length of stay (33.7 vs 43.6 days, P < .001). On multivariable regression, DT remained an independent predictor of sternal infection (adjusted odds ratio, 1.35; P < .05), in-hospital death (odds ratio, 1.36; P < .001), and length of stay (9.1 days, P < .001), with no difference in time from tracheostomy to discharge between the 2 cohorts (P = .40). CONCLUSIONS: In cardiac surgical patients, ET yielded similar postoperative outcomes, including sternal infection and in-hospital death. Our findings should reassure surgeons considering ET in poststernotomy patients with respiratory failure.
