- Advances in allogeneic hematopoietic cell transplantation for sickle cell disease have improved outcomes, but there is limited analysis of healthcare utilization in this setting. We hypothesized that, compared to late transplantation, early transplantation (at age < 10 years) improves outcomes and decreases healthcare utilization. We performed a retrospective study of children transplanted for sickle cell disease in the USA during 2000-2013 using two large databases. Univariate and Cox models were used to estimate associations of demographics, sickle cell disease severity, and transplant-related variables with mortality and chronic graft-versus-host disease, while Wilcoxon, Kruskal-Wallis, or linear trend tests were applied for the estimates of healthcare utilization. Among 161 patients with a 2-year overall survival rate of 90% (95% confidence interval [CI] 85-95%) mortality was significantly higher in those who underwent late transplantation versus early (hazard ratio (HR) 21, 95% CI 2.8-160.8, P=0.003) and unrelated compared to matched sibling donor transplantation (HR 5.9, 95% CI 1.7-20.2, P=0.005). Chronic graftversus host disease was significantly more frequent among those translanted late (HR 1.9, 95% CI 1.0-3.5, P=0.034) and those who received an unrelated graft (HR 2.5, 95% CI 1.2-5.4; P=0.017). Merged data for 176 patients showed that the median total adjusted transplant cost per patient was $467,747 (range: $344,029-$ 799,219). Healthcare utilization was lower among recipients of matched sibling donor grafts and those with low severity disease compared to those with other types of donor and disease severity types (P<0.001 and P=0.022, respectively); no association was demonstrated with late transplantation (P=0.775). Among patients with 2-year pre-and post-transplant data (n=41), early transplantation was associated with significant reductions in admissions (P<0.001), length of stay (P<0.001), and cost (P=0.008). Early transplant outcomes need to be studied prospectively in young children without severe disease and an available matched sibling to provide conclusive evidence for the superiority of this approach. Reduced post-transplant healthcare utilization inpatient care indicates that transplantation may provide a sustained decrease in healthcare costs over time.

- Follow-up is integral for hematopoietic cell transplantation (HCT) care to ensure surveillance and intervention for complications. We characterized the incidence of and predictors for being lost to follow-up. Two-year survivors of first allogeneic HCT (10,367 adults and 3865 children) or autologous HCT (7291 adults and 467 children) for malignant/nonmalignant disorders between 2002 and 2013 reported to the Center for International Blood and Marrow Transplant Research were selected. The cumulative incidence of being lost to follow-up (defined as having missed 2 consecutive follow-up reporting periods) was calculated. Marginal Cox models (adjusted for center effect) were fit to evaluate predictors. The 10-year cumulative incidence of being lost to follow-up was 13% (95% confidence interval [CI], 12% to 14%) in adult allogeneic HCT survivors, 15% (95% CI, 14% to 16%) in adult autologous HCT survivors, 25% (95% CI, 24% to 27%) in pediatric allogeneic HCT survivors, and 24% (95% CI, 20% to 29%) in pediatric autologous HCT survivors. Factors associated with being lost to follow-up include younger age, nonmalignant disease, public/no insurance (reference: private), residence farther from the tranplantation center, and being unmarried in adult allogeneic HCT survivors; older age and testicular/germ cell tumor (reference: non-Hodgkin lymphoma) in adult autologous HCT survivors; older age, public/no insurance (reference: private), and nonmalignant disease in pediatric allogeneic HCT survivors; and older age in pediatric autologous HCT survivors. Follow-up focusing on minimizing attrition in high-risk groups is needed to ensure surveillance for late effects.

- BACKGROUND: To evaluate the impact of depression before autologous and allogeneic hematopoietic cell transplantation (HCT) on clinical outcomes post-transplantation.METHODS: We analyzed data from the Center for International Blood and Marrow Transplant Research to compare outcomes after autologous (n=3786) or allogeneic (n=7433) HCT for adult patients with hematologic malignancies with an existing diagnosis of pre-HCT depression requiring treatment versus those without pre-HCT depression. Using Cox regression models, we compared overall survival (OS) between patients with or without depression. We compared the number of days alive and out of the hospital in the first 100 days post-HCT using Poisson models. We also compared the incidence of grade 2-4 acute and chronic graft-versus-host disease (GVHD) in allogeneic HCT.RESULTS: The study included 1116 (15%) patients with pre-transplant depression and 6317 (85%) without depression who underwent allogeneic HCT between 2008 and 2012. Pre-transplant depression was associated with lower OS (hazard ratio [HR], 1.13; 95% confidence interval [CI], 1.04-1.23; P=0.004) and a higher incidence of grade 2-4 acute GVHD (HR, 1.25; 95% CI, 1.14-1.37; P<0.0001), but similar incidence of chronic GVHD. Pre-transplant depression was associated with fewer days-alive-and-out-of-the hospital (means ratio [MR]=0.97; 95% CI, 0.95-0.99; P=0.004). There were 512 (13.5%) patients with Pre-transplant depression and 3274 (86.5%) without depression who underwent autologous HCT. Pre-transplant depression in autologous HCT was not associated with OS (HR, 1.15; 95% CI, 0.98-1.34; P=0.096) but was associated with fewer days alive and out of the hospital (MR, 0.98; 95% CI, 0.97-0.99; P=0.002).CONCLUSION: Pre-transplant depression was associated with lower OS and higher risk of acute GVHD among allogeneic HCT recipients and fewer days alive and out of the hospital during the first 100 days after autologous and allogeneic HCT. Patients with pre-transplant depression represent a population that is at risk for post-transplant complications.

- Background: The association of community factors and outcomes after hematopoietic cell transplantation (HCT) has not been comprehensively described. Using the County Health Rankings and Roadmaps (CHRR) and the Center for International Blood and Marrow Transplant Research (CIBMTR), this study evaluated the impact of community health status on allogeneic HCT outcomes.Methods: This study included 18,544 adult allogeneic HCT recipients reported to the CIBMTR by 170 US centers in 2014-2016. Sociodemographic, environmental, and community indicators were derived from the CHRR, an aggregate community risk score was created, and scores were assigned to each patient (patient community risk score [PCS]) and transplant center (center community risk score [CCS]). Higher scores indicated less healthy communities. The impact of PCS and CCS on patient outcomes after allogeneic HCT was studied.Results: The median age was 55 years (range, 18-83 years). The median PCS was -0.21 (range, -1.37 to 2.10; standard deviation [SD], 0.42), and the median CCS was -0.13 (range, -1.04 to 0.96; SD, 0.40). In multivariable analyses, a higher PCS was associated with inferior survival (hazard ratio [HR] per 1 SD increase, 1.04; 99% CI, 1.00-1.08;P= .0089). Among hematologic malignancies, a tendency toward inferior survival was observed with a higher PCS (HR, 1.04; 99% CI, 1.00-1.08;P= .0102); a higher PCS was associated with higher nonrelapse mortality (NRM; HR, 1.08; 99% CI, 1.02-1.15;P= .0004). CCS was not significantly associated with survival, relapse, or NRM.Conclusions: Patients residing in counties with a worse community health status have inferior survival as a result of an increased risk of NRM after allogeneic HCT. There was no association between the community health status of the transplant center location and allogeneic HCT outcomes.
