Participation in therapeutic clinical trials rarely reflects the race and ethnic composition of the patient population. To meet National Institutes of Health-mandated goals, strategies to increase participation are required. We present a framework for institutional enhancement of minority clinical trial accrual.
We implemented structural changes on four levels to induce and sustain minority accrual to clinical trials: (1) leadership support; (2) center-wide policy change; (3) infrastructural process control, data analysis, and reporting; and (4) follow-up with clinical investigators. A Protocol Review and Monitoring Committee reviews studies and monitors accrual, and the Program for the Elimination Cancer Disparities leads efforts for proportional accrual, supporting the system through data tracking, Web tools, and feedback to investigators.
Following implementation in 2005, minority accrual to therapeutic trials increased from 12.0 % in 2005 to 14.0 % in 2010. The "rolling average" minority cancer incidence at the institution during this timeframe was 17.5 %. In addition to therapeutic trial accrual rates, we note significant increase in the number of minorities participating in all trials (therapeutic and nontherapeutic) from 2005 to 2010 (346-552, 60 % increase, p < 0.05) compared to a 52 % increase for Caucasians.
Implementing a system to aid investigators in planning and establishing targets for accrual, while requiring this component as a part of annual protocol review and monitoring of accrual, offers a successful strategy that can be replicated in other cancer centers, an approach that may extend to other clinical and translational research centers.
参与治疗性临床试验的患者人群很少反映出种族和民族构成。为了实现美国国立卫生研究院规定的目标,需要采取增加参与的策略。我们提出了一个加强少数民族临床试验入组的机构框架。
我们在四个层面实施了结构性变革,以促进和维持少数民族参与临床试验:(1)领导层的支持;(2)中心范围内的政策变革;(3)基础设施的过程控制、数据分析和报告;以及(4)对临床研究者的后续跟进。协议审查和监测委员会审查研究并监测入组情况,消除癌症差异计划努力实现按比例入组,通过数据跟踪、网络工具和向研究者提供反馈来支持该系统。
在 2005 年实施后,治疗性试验的少数民族入组率从 2005 年的 12.0%增加到 2010 年的 14.0%。在此期间,该机构少数民族癌症发病率的“滚动平均值”为 17.5%。除了治疗性试验的入组率外,我们还注意到 2005 年至 2010 年期间,所有试验(治疗性和非治疗性)中少数民族参与者的数量显著增加(从 346 人增加到 552 人,增加了 60%,p<0.05),而白种人增加了 52%。
实施一个系统来帮助研究者规划和设定入组目标,同时要求将这一环节作为年度协议审查和入组监测的一部分,提供了一种成功的策略,可以在其他癌症中心复制,这种方法可能会扩展到其他临床和转化研究中心。
