    IntroductionRegional anesthesia has been shown to be efficacious for analgesia in patients who underwent thoracotomies. The objective of this study was to analyze the association of epidurals and peripheral regional anesthesia with time to hospital discharge for these patients.MethodsThis was a retrospective cohort study using National Surgical Quality Improvement Program dataset from 2014 to 2020. Propensity-matched cohorts were assembled based on use of regional anesthesia, peripheral regional anesthesia, or epidural. Fine-Gray competing risk regressions were used to explore the association between regional anesthesia use and rate of discharge. The subdistribution hazard ratio (HR) represented relative discharge rates, and in-hospital death was a competing event. A sensitivity analysis was subsequently performed in which patients with American Society of Anesthesiologists score ≥4 were removed.ResultsThere were 4350 patients included in this analysis, in which 472 (10.8%) received a peripheral regional anesthesia nerve block and 565 (13.0%) received thoracic epidural analgesia. The subdistribution HR for rate of discharge in the epidural versus non-epidural cohort was 1.09 (95% CI 1.01 to 1.18), thus epidurals were associated with an increased rate of discharge over time. However, this benefit was no longer apparent with the sensitivity analysis. The subdistribution HR for rate of discharge in the peripheral regional anesthesia versus no regional anesthesia cohort was 1.26 (95% CI 1.15 to 1.39), thus peripheral regional anesthesia was associated with an increased rate of discharge over time. This benefit remained even with the sensitivity analysis.ConclusionsThoracic epidural use when compared with no regional anesthesia was associated with decreased length of stay following thoracotomy in our primary analysis. The difference was no longer apparent with the sensitivity analysis. Peripheral regional anesthesia was associated with decreased length of stay even after sensitivity analysis.© American Society of Regional Anesthesia & Pain Medicine 2024. No commercial re-use.
