Allogeneic hematopoietic cell transplantation (alloHCT) is a highly specialized procedure. We surveyed adult transplant centers in the United States (US) and then used data reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) (2008-2010) to evaluate associations of center volume, infrastructure, and care delivery models with survival post alloHCT. Based on their 2010 alloHCT volume, centers were categorized as low-volume (≤40 alloHCTs; N = 42 centers, 1900 recipients) or high-volume (>40 alloHCTs; N = 41 centers, 9637 recipients). 100-day survival was 86% (95% CI, 85-87%) in high-volume compared with 83% (95% CI, 81-85%) in low-volume centers (difference 3%; P < 0.001). One-year survival was 62% (95% CI, 61-63%) and 56% (95% CI, 54-58%), respectively (difference 6%; P < 0.001). Logistic regression analyses adjusted for patient and center characteristics; alloHCT at high-volume centers (odds ratio [OR] 1.32; P < 0.001) and presence of a survivorship program dedicated to HCT recipients (OR 1.23; P = 0.009) were associated with favorable 1-year survival compared to low-volume centers. Similar findings were observed in a CIBMTR validation cohort (2012-2014); high-volume centers had better 1-year survival (OR 1.24, P < 0.001). Among US adult transplant centers, alloHCT at high-volume centers and at centers with survivorship programs is associated with higher 1-year survival.
