Inpatient Healthcare Resource Utilization, Costs, and Mortality in Adult Patients with Acute Graft-versus-Host Disease, Including Steroid-Refractory or High-Risk Disease, following Allogeneic Hematopoietic Cell Transplantation.

Acute graft-versus-host disease (GVHD) contributes to poor outcomes following allogeneic hematopoietic cell transplantation (HCT). Data are limited regarding the economic burden of acute GVHD, particularly steroid-refractory or high-risk (SR/HR) disease. This retrospective analysis of the Premier Healthcare Database reports inpatient healthcare resource utilization (HCRU), costs, and mortality during initial hospitalization for allogeneic HCT and through 100 days post-HCT among patients who developed acute GVHD, including a subgroup with SR/HR disease, compared with patients without GVHD. The analysis included adults discharged for first HCT between January 1, 2011, and June 30, 2016 (acute GVHD, n = 906; SR/HR acute GVHD, n = 158; no GVHD, n = 1529). During the initial hospitalization for HCT, patients with acute GVHD and SR/HR acute GVHD (n = 455 and 125, respectively) had significantly longer median lengths of stay (31 and 46 days versus 24 days) and higher median total costs ($153,849 and $205,880 versus $97,417) versus patients with no GVHD (n = 1529; P < .0001 for all). During the 100-day post-HCT period, patients with acute GVHD and SR/HR acute GVHD had higher readmission rates (78.3% and 77.2% versus 28.3%; P < .0001) and inpatient mortality rates (20.2% and 35.4% versus 8.9%; P < .0001) versus patients with no GVHD. In summary, acute GVHD, especially SR/HR disease, is associated with longer inpatient stays, higher readmission rates, and higher inpatient mortality compared with no GVHD.
