INTRODUCTION Participant retention is important to maintaining statistical power, minimizing bias, and preventing scientific error in Alzheimer disease and related dementias research. METHODS We surveyed representative investigators from NIH-funded Alzheimer's Disease Research Centers (ADRC), querying their use of retention tactics across 12 strategies. We compared survey results to data from the National Alzheimer's Coordinating Center for each center. We used a generalized estimating equation with independent working covariance model and empirical standard errors to assess relationships between survey results and rates of retention, controlling for participant characteristics. RESULTS Twenty-five (83%) responding ADRCs employed an average 42 (SD=7) retention tactics. In a multivariable model that accounted for participant characteristics, the number of retention tactics used by a center was associated with participant retention (odds ratio=1.68, 95% confidence interval: 1.42, 1.98; P<0.001 for the middle compared with the lowest tertile survey scores; odds ratio=1.59, 95% confidence interval: 1.30, 1.94; P<0.001 for the highest compared with the lowest tertile survey scores) at the first follow-up visit. Participant characteristics such as normal cognition diagnosis, older age, higher education, and Caucasian race were also associated with higher retention. CONCLUSIONS Retention in clinical research is more likely to be achieved by employing a variety of tactics.

保留阿尔茨海默氏病研究参与者。

引言参加者保留对于维持统计能力,最小化偏见以及防止阿尔茨海默病和相关痴呆症研究中的科学错误很重要。方法我们调查了美国国立卫生研究院资助的阿尔茨海默氏病研究中心(ADRC)的代表性研究人员,询问他们在12种策略中使用保留策略的情况。我们将调查结果与国家阿尔茨海默氏症协调中心针对每个中心的数据进行了比较。我们使用具有独立工作协方差模型和经验标准误差的广义估计方程来评估调查结果与保留率之间的关系,并控制参与者的特征。结果二十五个(83%)响应的ADRC采用了平均42(SD = 7)个保留策略。在考虑参与者特征的多变量模型中,中心使用的保留策略数量与参与者保留相关(优势比= 1.68,95%置信区间:1.42,1.98;中位P <0.001,最低三分位数调查分数;比值比= 1.59,95%置信区间:1.30,1.94;在第一次随访随访中,最高和最低三分位数调查得分相比,P <0.001)。参与者的特征,例如正常的认知诊断,年龄较大,受过高等教育和高加索人种,也与较高的保留率相关。结论采用各种策略更可能实现临床研究的保留。1.98; 与最低三分位数调查得分相比,中位数P <0.001;比值比= 1.59,95%置信区间:1.30,1.94; 第一次随访时,最高和最低三分位数调查得分P <0.001)。参与者的特征,例如正常的认知诊断,年龄较大,受过高等教育和高加索人种,也与较高的保留率相关。结论采用各种策略更可能实现临床研究的保留。1.98; 与最低三分位数调查得分相比,中位数P <0.001;比值比= 1.59,95%置信区间:1.30,1.94; 第一次随访时,最高和最低三分位数调查得分P <0.001)。参与者的特征,例如正常的认知诊断,年龄较大,受过高等教育和高加索人种,也与较高的保留率相关。结论采用各种策略更可能实现临床研究的保留。高加索人种和种族保留率也较高。结论采用各种策略更可能实现临床研究的保留。高加索人种和种族保留率也较高。结论采用多种策略更可能实现临床研究的保留。
