Predictors And Outcomes Of Unplanned Early Rehospitalization In The First Year Following Lung Transplantation

Unplanned early rehospitalization (UER), defined as an unscheduled admission within 30 days of a hospital discharge, is associated with graft loss and recipient mortality in some solid organ transplants but has not been investigated in lung transplant. In this retrospective study, we collected socio demographic and clinical factors to determine predictors and outcomes of UER in the first year following lung transplantation. There were 193 patients who underwent lung transplantation and survived to discharge during the 7.9 year study period. There were 116 (60.1%) patients with at least one UER. Infections (32.8%) and post surgical complications (11.8%) were the most common reasons for UER. On multivariate analysis, the strongest predictor of having an UER was discharge to a long term acute care facility (odds ratio: 3.01, 95% confidence interval [CI] 1.46-6.20; P=.003). Patients with any UER in the first year following transplantation had worse adjusted survival (hazard ratio: 1.89, 95% CI 1.02-3.50; P=.04). It is unclear, however, to what extent UERs reflect preventable outcomes. Further large scale, prospective research is needed to identify the extent to which certain types of UER are modifiable and to define patients at high risk for preventable UER.
