使用在线注册来有效地识别患有认知能力下降和阿尔茨海默病(AD)的老年人是一种可行性和有效性证据越来越多的方法。关联的生物标志物和登记数据可以促进AD临床研究。我们收集了老年人脑健康登记处(BHR)参与者的血液进行血浆生物标志物和遗传分析,评估了可行性,并估计了人口统计变量与研究参与之间的关联。在受邀参加研究的7150名参与者中,864名(12%)入组,629名(73%)完成远程抽血。参与者报告了较高的研究可接受性。那些来自代表性不足的民族文化和教育群体的人参与的可能性较小。这项研究证明了从老年人的大型代表性样本中远程采血的挑战。在短时间内从> 600名参与者的远程血液收集证明了我们的方法的可行性,该方法可以扩展以有效收集血浆AD生物标志物和遗传数据。
Use of online registries to efficiently identify older adults with cognitive decline and Alzheimer's disease (AD) is an approach with growing evidence for feasibility and validity. Linked biomarker and registry data can facilitate AD clinical research. We collected blood for plasma biomarker and genetic analysis from older adult Brain Health Registry (BHR) participants, evaluated feasibility, and estimated associations between demographic variables and study participation. Of 7150 participants invited to the study, 864 (12%) enrolled and 629 (73%) completed remote blood draws. Participants reported high study acceptability. Those from underrepresented ethnocultural and educational groups were less likely to participate. This study demonstrates the challenges of remote blood collection from a large representative sample of older adults. Remote blood collection from > 600 participants within a short timeframe demonstrates the feasibility of our approach, which can be expanded for efficient collection of plasma AD biomarker and genetic data.
