It is important to design clinical trials to include all those who may benefit from the intervention being tested. Several frameworks have been developed to help researchers think about the barriers to inclusion of particular under-served groups when designing a trial, but there is a lack of practical guidance on how to implement these frameworks. This paper describes the ACCESS project, the findings from each phase of the project and the guidance we developed (STEP UP) on how to design more inclusive trials.
Development of the STEP UP guidance had five phases: (1) Scoping literature review, (2) 'roundtable' discussion meetings, (3) redesign of trials, (4) interviews and (5) guidance document development, with input from public contributors and the ACCESS team.
Over 40 experts contributed to the ACCESS project-patients and the public, clinicians, NHS research staff, trialists and other academics. The scoping review identified several strategies being used to improve inclusion, mostly around recruitment settings, but there was little evaluation of these strategies. The 'roundtable' discussions identified additional strategies being used across the UK and Ireland to improve inclusion, which were grouped into: Communication, Community engagement, Recruitment sites, Patient information, Flexibility, Recruitment settings, Consent process, Monitoring, Training for researchers and Incentives. These strategies were used to redesign three existing trials by applying one of the three INCLUDE frameworks (ethnicity, socioeconomic disadvantage, impaired capacity to consent) to one trial each, to produce the key recommendations for the guidance. Issues around implementation were explored in stakeholder interviews and key facilitators were identified: funders requesting information on inclusion, having the time and funding to implement strategies, dedicated staff, flexibility in trial protocols, and considering inclusion of under-served groups at the design stages. The STEP UP guidance is freely available at http://step-up-clinical-trials.co.uk .
Researchers should consider inclusivity to shape initial trial design decisions. Trial teams and funders need to ensure that trials are given both the resources and time needed to implement the STEP UP guidance and increase the opportunities to recruit a diverse population.
设计临床试验以纳入所有可能从所测试干预中获益的人群非常重要。有几个框架已被开发出来,以帮助研究人员在设计试验时思考将特定服务不足的群体纳入其中的障碍,但缺乏关于如何实施这些框架的实用指导。本文介绍了 ACCESS 项目、项目各阶段的发现以及我们制定的关于如何设计更具包容性试验的指导(STEP UP)。
STEP UP 指导的制定分为五个阶段:(1)文献范围界定综述,(2)“圆桌”讨论会议,(3)试验重新设计,(4)访谈,以及(5)指导文件制定,均有来自公众参与者和 ACCESS 团队的投入。
超过 40 名专家参与了 ACCESS 项目——患者和公众、临床医生、NHS 研究人员、试验人员和其他学者。范围界定综述确定了几种用于提高纳入率的策略,主要集中在招募环境方面,但对这些策略的评价很少。“圆桌”讨论确定了英国和爱尔兰各地用于提高纳入率的其他策略,这些策略被分为:沟通、社区参与、招募地点、患者信息、灵活性、招募环境、知情同意过程、监测、研究人员培训和激励措施。这些策略被用于通过将三个 INCLUDE 框架(种族、社会经济劣势、同意能力受损)中的一个应用于每个试验,重新设计三个现有试验,从而为指导提供关键建议。在利益相关者访谈中探讨了实施方面的问题,并确定了关键促进因素:资助者要求提供纳入情况的信息、有时间和资金来实施策略、有专门人员、试验方案具有灵活性、以及在设计阶段考虑服务不足的群体。STEP UP 指导可在 http://step-up-clinical-trials.co.uk 免费获取。
研究人员应考虑包容性以影响初始试验设计决策。试验团队和资助者需要确保试验获得实施 STEP UP 指导所需的资源和时间,并增加招募多样化人群的机会。
