Hematopoietic cell transplantation (HCT) is a highly specialized, expensive and resource-intense medical procedure that can be associated with racial disparities. We review the prevailing literature on racial disparities in HCT in the United States and describe areas for future research and interventions. We discuss the complexity of interpreting race as a biological and social determinant of disease in biomedical research, especially as it relates to HCT. In the United States, race is often a surrogate for socioeconomic, education and health insurance status. We also discuss some of the nuances to consider while reviewing the literature on racial disparities. Disparities by race exist in three areas related to HCT: donor availability, access to HCT and outcomes of HCT. African-Americans/Blacks have a lower likelihood of finding an unrelated donor. Race and ethnicity definitions are country-specific and reconciling race data can represent significant challenges to unrelated donor registries worldwide. African-Americans/Blacks do not have the same access to autologous and allogeneic HCT as Whites. Racial disparities in outcomes of HCT are more prevalent among allogeneic HCT than autologous HCT recipients. More research is required to understand the biological, social, cultural, medical and financial aspects of race that may influence access to HCT and survival after transplantation. Better understanding of racial disparities will minimize inequities, inform health policy, guide development of interventions targeted to eliminate disparities and ensure equitable access to HCT for all populations.
Informed consent is essential to ethical research and is requisite to participation in clinical research. Yet most hematopoietic cell transplantation (HCT) informed consent forms (ICFs) are written at reading levels that are above the ability of the average person in the US. The recent development of ICF templates by the National Cancer Institute, National Institutes of Health and the National Heart Blood and Lung Instituthas not resulted in increased patient comprehension of information. Barriers to creating Easy-to-Read ICFs that meet US federal requirements and pass Institutional Review Board (IRB) review are the result of multiple interconnected factors. The Blood and Marrow Transplant Clinical Trials Network (BMT CTN) formed an ad hoc review team to address concerns regarding the overall readability and length of ICFs used for BMT CTN trials. This paper summarizes recommendations of the review team for the development and formatting of Easy-to-Read ICFs for HCT multicenter clinical trials, the most novel of which is the use of a two-column layout. These recommendations intend to guide the ICF writing process, simplify local IRB review of the ICF, enhance patient comprehension and improve patient satisfaction. The BMT CTN plans to evaluate the impact of the Easy-to-Read format compared to the traditional format on the informed consent process.
Hematopoietic cell transplantation (HCT) is a curative therapy for patients with malignant and nonmalignant bone marrow disorders. Life after transplantation can vary significantly among HCT recipients, who deal with a variety of physical and emotional issues. This presents numerous challenges, particularly for rural recipients who are required to travel long distances to access specialized HCT care. The objective of this study was to better understand barriers to providing care for HCT recipients living in rural areas. This study uses a cross-sectional design to collect primary data via an Internet survey of HCT healthcare providers. The authors analyzed factors restricting post-HCT care and whether having standard post-transplantation care instructions influenced the resources provided to distant-to-care recipients. Respondents reported limited transportation, coordination of care, and distance to facility as major barriers to post-HCT care, regardless of the number of distant-to-care recipients treated annually. HCT centers with standard post-transplantation care instructions were more likely to provide visits from social workers and medical leave resources to distant-to-care recipients. These instructions may improve recipient and local provider ability to make informed decisions regarding post-HCT care. The findings will help guide the development of programs and resources targeted to recipients of HCT who are distant to care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
