Study Procedures

This study was approved by the National Marrow Donor Program Institutional Review Board. We conducted a cross-sectional, web-based survey of transplant physicians. Participants were recruited from the American Society for Blood and Marrow Transplantation (ASBMT) membership list between January and February 2017. Eligible participants were transplant physicians who provide direct clinical care to HSCT patients in the United States. Participants were recruited via an email invitation explaining the purpose of the study, which included a link encouraging them to participate through the “Survey Gizmo” platform. Survey-Gizmo (Boulder, CO) is a secure, password protected tool that has been used extensively for survey administration. A total of five follow-up email contacts were made to non-responders, with email reminders sent on the second, third, fifth, and sixth week from the initial invitation. Participants who completed the survey could choose to receive honoraria, via a $50 gift card.
