Firstly, to determine if attendance for second round mammography screening in those sent a tailored letter (that is, making reference to their screening history) is increased compared with those sent a standard letter; secondly, to investigate the acceptability of tailored letters.
North West Glasgow Breast Screening Centre.
A randomised controlled trial.
Overall attendance was unrelated to whether the women were sent a tailored or standard letter; 60% of those sent the standard letter attended (922/1531) compared with 62% of those sent the tailored letter (956/1552) (chi 2 = 0.61, P = 0.4) (difference 2%; 95% confidence interval -2% to 5%). There were no significant differences in percentage attendance within each of the study subgroups: women who attended previously and received an all clear result, women who attended previously and received a false positive result, women who were invited previously and failed to attend, and women who were previously too young to be invited for screening. However, there was a statistically significant difference in percentage attendance between these four groups, independent of letter type (chi 2 = 510, P < 0.00001). Although women found the letters acceptable and understandable, they did not seem to pay close attention to the content.
Tailoring invitation letters does not have a significant effect on uptake rates for breast screening and does not justify the additional workload required.
首先，确定收到定制信件（即提及她们的筛查历史）的女性进行第二轮乳房X线筛查的出勤率是否高于收到标准信件的女性；其次，调查定制信件的可接受性。
格拉斯哥西北部乳房筛查中心。
一项随机对照试验。
总体出勤率与女性收到的是定制信件还是标准信件无关；收到标准信件的女性中有60%参加了筛查（922/1531），而收到定制信件的女性中有62%参加了筛查（956/1552）（卡方=0.61，P=0.4）（差异2%；95%置信区间-2%至5%）。在每个研究亚组中，出勤率百分比没有显著差异：之前参加过筛查且结果为一切正常的女性、之前参加过筛查且结果为假阳性的女性、之前被邀请但未参加的女性，以及之前因年龄太小而未被邀请进行筛查的女性。然而，这四组之间的出勤率百分比存在统计学上的显著差异，与信件类型无关（卡方=510，P<0.00001）。尽管女性认为这些信件是可以接受的且易于理解，但她们似乎并未密切关注信件内容。
定制邀请信对乳房筛查的参与率没有显著影响，也无法证明所需增加的工作量是合理的。
