QOL data will be collected at baseline (pre-transplant), 100 days, 6 months, and 12 months post transplant. The transplant center will consent the patient and administer the baseline QOL surveys. The transplants center will then submit the competed baseline data and patient contact information to the Center for International Blood and Marrow Transplant Research (CIBMTR). The remaining surveys will be administered to the patient from the CIBMTR via paper surveys mailed to the patient.
