Early readmission is a predictor of overall survival following isolated lung transplantation.

Causes of early readmissions following lung transplantation are not well understood, and the impact is poorly reported. We reviewed 221 consecutive lung transplantations and identified patients readmitted within 90 days. A case control analysis was performed to determine the characteristics that predict readmission and the impact of readmission on survival. Ninety (44%) of the 205 operative survivors required a total of 125 readmissions during the 90 days after transplantation. Twenty-eight patients (13.7%) required multiple readmissions. Causes for readmissions were pulmonary complication (59%), gastrointestinal (18%), cardiac (5%), metabolic (2.5%), neurological (2.5%), hematological (2%), and miscellaneous (11%). The sex, native disease, or type of transplant did not predict readmission. Requirement of cardiopulmonary bypass for transplantation showed a trend toward significance (P = 0.08). The 90-day conditional survival at 1, 3, and 5 years for those patients readmitted within 90 days were 76%, 59%, and 52%, respectively, compared to 93%, 80%, and 76% for patients not readmitted (P = 0.01). Requirement for readmission within 90 days following transplantation is associated with increased mortality. Sex, native disease, and type of transplant are not predictors of readmission or survival.
