To investigate whether appointments for screening timed in proximity to annual milestones (birthdays, Christmas and New Year) may be used as a strategy to improve attendance for screening for colorectal cancer.
Randomised controlled trial.
City of Oslo (urban) and Telemark county (urban and rural), Norway.
12,960 screened adults (64.7% of those invited).
Attendance rates for each week and month of assigned appointment.
Attendance rates were significantly higher in December than the rest of the year (72.3% v 64.6%, P<0.001) in adults who received an invitation in the week of their birthday or were assigned to screening in the first or second week after their birthday (67.9% v 64.5%, P=0.007). This effect was most pronounced in the urban population of Oslo. In a multivariable logistic regression model, attendance improved in those who received an invitation in the week of their birthday or were assigned to screening in the first or second week after their birthday (odds ratio 1.15, 95% confidence interval 1.03 to 1.28) and those who were assigned to screening in December (odds ratio 1.45, 1.16 to 1.82).
Attendance rates for screening for colorectal cancer were higher in December and around attendees' birthdays, the latter particularly in an urban population. Compliance with screening programmes may therefore be improved by timing invitations in proximity to annual milestones.

调查将结直肠癌筛查预约安排在接近年度重要日子（生日、圣诞节和新年）的时间是否可作为提高筛查出勤率的一种策略。
随机对照试验。
挪威奥斯陆市（城市）和泰勒马克郡（城市及农村）。
12960名接受筛查的成年人（占受邀者的64.7%）。
指定预约时间的每周和每月出勤率。
在生日当周收到邀请或被安排在生日后的第一或第二周进行筛查的成年人中，12月的出勤率显著高于一年中的其他时间（72.3%对64.6%，P<0.001）（67.9%对64.5%，P=0.007）。这种效应在奥斯陆的城市人口中最为明显。在多变量逻辑回归模型中，在生日当周收到邀请或被安排在生日后的第一或第二周进行筛查的人（优势比1.15，95%置信区间1.03至1.28）以及被安排在12月进行筛查的人（优势比1.45，1.16至1.82）的出勤率有所提高。
结直肠癌筛查的出勤率在12月以及参与者生日前后较高，后者在城市人口中尤为明显。因此，通过在接近年度重要日子时安排邀请时间，可能会提高筛查项目的依从性。
临床试验编号NCT00119912。
