METHODS:: RESULTS:: Patients randomized to opt-in agreed to participate 23.1% of the time, and only 2.5% of those in opt-out chose not to participate. FIT kits were mailed to 22.4% and 93% of patients in opt-in and opt-out arms, respectively. In intention-to-screen analysis, patients in the opt-out arm had a higher FIT completion rate (29.1%) than in the opt-in arm (9.6%) (absolute difference 19.5%; 95% confidence interval, 10.9-27.9%; P < .001). Results were similar in subgroup analysis of those sent initial messaging through the EHR portal (9.5% opt-in versus 37.5% in opt-out).
方法:结果:选择参与的患者随机分配到同意组的比例为 23.1%,而选择不参与的患者中只有 2.5%来自退出组。意向性筛选分析中,退出组的 FIT 完成率(29.1%)高于同意组(9.6%)(绝对差异 19.5%;95%置信区间,10.9-27.9%;P <.001)。在通过电子病历门户发送初始消息的亚组分析中,结果相似(9.5%的同意组与退出组的 37.5%)。
