Despite bearing a disproportionate burden of heart failure (HF), Black and Hispanic individuals have been poorly represented in HF clinical trials. Underrepresentation in clinical trials limits the generalizability of the findings to these populations and may even introduce uncertainties and hesitancy when translating trial data to the care of people from underrepresented groups. The Heart Failure Collaboratory, a consortium of stakeholders convened to enhance HF therapeutic development, has been dedicated to improving recruitment strategies for patients from diverse and historically underrepresented groups.
Despite federal policies from the US Food and Drug Administration and National Institutes of Health aimed at improving trial representation, gaps in trial enrollment proportionate to the racial and ethnic composition of the HF population have persisted. Increasing trial globalization with limited US enrollment is a major driver of these patterns. Additional barriers to representative enrollment include inequities in care access, logistical issues in participation, restrictive enrollment criteria, and English language requirements.
Strategies for improving diverse trial enrollment include methodical study design and site selection, diversification of research leadership and staff, broadening of eligibility criteria, community and patient engagement, and broad stakeholder commitment. In contemporary HF trials, diverse trial enrollment is not only feasible but can be efficiently achieved to improve the generalizability and translation of trial knowledge to clinical practice.
尽管黑人及西班牙裔人群承担着不成比例的心衰负担,但他们在心力衰竭临床试验中的代表性严重不足。临床试验中代表性不足限制了研究结果在这些人群中的普遍性,甚至在将试验数据转化为代表性不足人群的护理时会引入不确定性和犹豫。心力衰竭协作研究中心是一个由利益相关者组成的联盟,旨在加强心力衰竭治疗的开发,一直致力于改善来自不同和历史上代表性不足群体的患者的招募策略。
尽管美国食品和药物管理局和美国国立卫生研究院有联邦政策旨在改善试验代表性,但与心力衰竭人群的种族和民族构成相称的试验参与率差距仍然存在。随着有限的美国参与,试验全球化的增加是造成这些模式的主要原因。代表性参与的其他障碍包括护理机会的不平等、参与的后勤问题、限制准入标准以及对英语的要求。
改善多样化试验参与的策略包括有条不紊的研究设计和选址、研究领导和工作人员的多样化、扩大资格标准、社区和患者参与以及广泛的利益相关者承诺。在当代心力衰竭试验中,多样化的试验参与不仅是可行的,而且可以有效地实现,以提高试验知识在临床实践中的普遍性和转化。
