Mammography Screening Decisions in the Elderly

描述（由申请人提供）：80岁及以上女性乳房X线摄影筛查的益处尚不确定。指南鼓励医生在筛查老年妇女之前考虑预期寿命，并与老年患者讨论筛查的风险和益处。尽管有这些建议，许多老年妇女甚至健康状况不佳的妇女也接受了筛查。目前还不清楚为什么这么多老年妇女选择接受筛查，以及影响这一决定的因素是什么。为了确定老年妇女对筛查性乳房X线摄影的了解的准确性以及影响筛查决定的因素，申请人提出了一项两阶段研究。第一阶段采用定性方法，对老年人进行乳腺X线摄影筛查决策调查，第二阶段对80岁及以上的妇女进行更大样本的调查，并将50-69岁的妇女作为对照组。将进行双变量分析和多变量logistic回归，以比较老年患者和年轻患者之间筛选知识的准确性，并确定几个因素对筛选决定的影响的年龄差异。这是第一项研究，探讨非常老年妇女的方法来决定筛查乳房X光检查。

DESCRIPTION (provided by applicant): The benefits of mammography screening in women age 80 and older are uncertain. Guidelines encourage physicians to consider life expectancy before screening elderly women and to discuss the risks and benefits of screening with their elderly patients. Despite these recommendations, many elderly women are screened even those in poor health. It is unknown why so many elderly women are choosing to be screened and what factors influence this decision. To determine the accuracy of elderly women's knowledge about screening mammography and factors that influence screening decisions, the applicant proposes a two-phase study. Phase 1 uses qualitative methods to develop a survey about mammography screening decisions in the elderly and phase 2 involves administering the survey to a larger sample of women age 80 and older, using women ages 50-69 as a comparison group. Bivariable analyses and multivariable logistic regression will be performed to compare the accuracy of screening knowledge between elderly and younger patients as well as to determine age differences in the influence of several factors on the decision to be screened. This is the first study to explore very elderly women's approach to decisions about screening mammography.
