Identifying Best Approach in Improving Quality of Life and Survival After a Donor Stem Cell Transplant in Older, Medically Infirm, or Frail Patients With Blood Diseases

OUTLINE: Patients are randomized to 1 of 4 arms. ARM I: Patients undergo SPC on days -15 before to +56 after transplant. ARM II: Patients undergo a CMC program on days -15 before to +56 after transplant. ARM III: Patients undergo interventions as outlined in Arm I and Arm II. ARM IV: Patients receive standard of care. In all arms, patients undergo HCT on day 0 and complete questionnaires and surveys at enrollment and 30, 90, 180, and 365 days post HCT. In all arms patients complete a 4-meter walk test, 6-minute walk test, up and go test, measured strength test and cognitive assessment at enrollment, 90, 180, and 365 days post HCT. Patients may also complete surveys on medical and non-medical (transportation, lodging) costs related to transplant after HCT.
