Abstract
BACKGROUND: There is little in the literature pertaining to cost associated with the use of extracorporeal membrane oxygenation (ECMO) in lung transplantation. We sought to evaluate charges associated with the index hospitalization among recipients of a lung transplant who required ECMO to identify factors that increase hospital charges in these patients. METHODS: With the use of the Nationwide Inpatient Sample, we reviewed data pertaining to patients who received a lung transplant between 2000 and 2011 and stratified them into ECMO and non-ECMO groups based on use of ECMO. Regression modeling was used to identify differences in charges. RESULTS: Data pertaining to 15,596 recipients of a lung transplant were evaluated, 658 (4.2%) of whom required ECMO. ECMO recipients were more likely to have a diagnosis of idiopathic pulmonary fibrosis (3.5% versus 1.3%, p = 0.007) or pulmonary hypertension (PH) (9.1% versus 3.0%, p < 0.001). Patients who received a bilateral lung transplant had 32.1% (95% confidence interval [CI]: 26.2% to 37.9%, p < 0.001) higher charges. Recipients with PH had 28.7% (95% CI: 14.9% to 42.4%, p = 0.001) higher charges. Median charges for recipients of a lung transplant who required ECMO were $780,391.50 versus $324,279.80 for non-ECMO recipients of a lung transplant and were 50.3% (95% CI: 33.0% to 67.5%, p < 0.001) higher. Hospital charges among Medicare enrollees were 6.6% (95% CI: 0.7% to 12.5%, p = 0.028) higher than privately insured recipients of a lung transplant. Black recipients had approximately 34.2% (95% CI: 3.2% to 65.0%, p = 0.030) higher charges. The ECMO group had longer median length of stay (LOS) (25 versus 15 days, p < 0.001). CONCLUSIONS: Recipients of a lung transplant who required ECMO support had longer LOS and higher hospital charges, specifically among black recipients, recipients with PH, and Medicare enrollees.
