The objective of this study was to evaluate a pilot program that allowed Chicago field center participants of the Coronary Artery Risk Development in Young Adults (CARDIA) study to submit follow-up information electronically (eCARDIA).
Chicago field center participants who provided email addresses were invited to complete contact information and follow-up questionnaires on medical conditions electronically in 2012-2013. Sociodemographic characteristics were compared between those who did and did not complete follow-up electronically. The number of participant contacts by CARDIA staff needed before follow-up was completed was also evaluated.
Blacks and low socioeconomic position individuals were less likely to complete follow-up using the electronic questionnaire. Participants who used the electronic questionnaire for follow-up needed fewer contacts (e.g., median 1 contact compared with 3for contact information follow-up), but they also needed fewer contacts prior to eCARDIA (median 1 before and after eCARDIA).
Findings suggest other approaches will be needed to maintain contact and elicit follow-up information from harder-to-reach individuals.
本研究的目的是评估一项试点项目，该项目允许青年成人冠状动脉风险发展研究（CARDIA）芝加哥现场中心的参与者以电子方式提交随访信息（eCARDIA）。
2012 - 2013年，邀请提供了电子邮件地址的芝加哥现场中心参与者以电子方式完成联系信息和关于医疗状况的随访问卷。比较了以电子方式完成随访和未完成随访者的社会人口学特征。还评估了在完成随访之前CARDIA工作人员需要与参与者进行联系的次数。
黑人和社会经济地位较低的个体使用电子问卷完成随访的可能性较小。使用电子问卷进行随访的参与者需要的联系次数较少（例如，随访信息的中位数为1次联系，而联系信息随访为3次），但在使用eCARDIA之前他们也需要较少的联系（eCARDIA前后中位数均为1次）。
研究结果表明，需要采用其他方法来与难以联系到的个体保持联系并获取随访信息。
