PURPOSE Patients who undergo allogeneic hematopoietic stem-cell transplantation (allo-HSCT) usually require a prolonged hospital stay that varies greatly across patients. Limited information exists on the factors associated with hospital length of stay (LOS) after allo-HSCT and the impact on transplant-related costs. The objective of this study was to determine predictors for longer LOS for allo-HSCT and to assess their impact on the cost of transplant stay. METHODS Using the National Inpatient Sample database, adult patients hospitalized for allo-HSCT were identified using International Classification of Diseases, Ninth Revision, primary and secondary procedure codes. RESULTS Between 2002 and 2015, 68,296 hospitalizations for allo-HSCT were identified. Peripheral blood was the most common stem-cell source (80%) followed by bone marrow (15%) and cord blood (5%). Median LOS was 25.8 days (interquartile range [IQR], 21-34.0 days), and the overall inpatient mortality rate was 8%. Stem-cell source was a significant predictor for longer LOS, being significantly longer for cord blood (median, 36.9 days; IQR, 26.7-49.9 days) compared with bone marrow (median, 27.2 days; IQR, 21.5-35.2 days) and peripheral blood (median 25.4 days; IQR, 20.8-32.7 days). Other predictors for longer LOS were patient characteristics such as age and race, transplant/post-transplant characteristics, and complications such as total body irradiation use, acute graft-versus-host disease, and infections. Longer LOS was also found to be associated with higher hospital costs. CONCLUSION In patients who undergo allo-HSCT, LOS can be predicted using patient- and transplant-related characteristics as well as post-transplant complications. LOS is also a driver for increased cost, and further efforts are needed to mitigate transplant complications and resource utilization.
