- Abstract
Background: We aimed to determine dysphagia profiles before and after lung transplantation (prevalence, incidence) and to examine predictors and health-related outcomes of aspiration in individuals undergoing lung transplantation., Methods: A retrospective single-center study of consecutive adults undergoing lung transplantation and completing a postoperative videofluoroscopic swallowing study between 2017 and 2020 was conducted. The validated penetration aspiration scale indexed swallowing safety and clinical outcomes were extracted from electronic medical records. T-tests, chi square with odds ratios, and multivariable logistic regression were conducted., Results: Two hundred five participants were identified who underwent lung transplantation and a postoperative swallowing exam. Of those who underwent both a pre- and postoperative swallowing exam (n = 170), preoperatively 83% demonstrated safe swallowing and 17% unsafe swallowing. Following lung transplantation, 16% demonstrated safe swallowing and 84% demonstrated unsafe swallowing (39% penetration, 45% aspiration). Independent predictors of postoperative aspiration were venous-venous extracorporeal membrane oxygenation (odds ratio [OR]: 6.7, confidence interval [CI]: 2.0-81.5) and reintubation (OR: 4.5, CI: 1.0-60.3), p < .05. Compared to non-aspirators, aspirators demonstrated higher odds of being discharged to a dependent care setting (OR: 2.3, CI: 1.2-4.5), p < .05. Aspirators spent significantly longer NPO (median = 138.0 hours, 25th percentile, 75th percentile = 75.7, 348.3) compared to non-aspirators (median = 85.0 hours, 25th percentile, 75th percentile = 48.0, 131.6, p < .001)., Conclusions: Pre-existing dysphagia was low in this cohort of patients undergoing lung transplantation, however increased approximately 5-fold following lung transplantation and was associated with increased morbidity., (Copyright © 2022 International Society for Heart and Lung Transplantation.
