Care Alliance. Clinical information was obtained from the institutional database. Multiple linear regression was used to analyze the patient and transplant characteristics that are associated with total costs. Results: Median age was 50 years (range 21 to 69 years), and 62% patients were male. Seventy eight percent transplants were for acute leukemia/MDS. Reasons for second transplant were graft failure (25%), relapse of original disease (65%) and other causes e.g. secondary MDS/aplasia (10%).

Non-myeloablative conditioning was more common in the second allografts (75%) than in first allografts (30%) and a higher proportion of second allografts were from unrelated donors (76% vs. 43%). In the first 100 days, relapse occurred in 25% patients and 64% experienced $ grade II acute GVHD. Survival was 78% at 100 days and 49% at one year after transplant. Regimen related toxicity accounted for 75% of deaths within the first 100 days. The median total cost in 2010 dollars was $137,600 ($4,500 -$434,200) for the first 100 days, with approximately $135,600 (0 -$432,200) for inpatient and $4,100 (0 -$17,200) for outpatient costs. The median length of hospital stay was 22 days (range 0 to 77 days). Myeloablative conditioning, unrelated donors and pulmonary complications post-transplant were significant predictors of higher costs for the second transplants.
