Shared Decision-making and Colorectal Cancer Screening

Conduct a feasibility pilot RCT of a newly developed colorectal cancer screening (CRC) decision aid (DA) including 66 LHL adults 76-85 years recruited from community health centers. Hypotheses: Patients in the intervention group will be more likely to change their intentions to be screened with fewer patients with <10 year LE and/or those with >10 year LE and no risk factors intending to be screened and more with >10 year LE and risk factors for CRC and/or those who have never been screened intending to be screened (primary outcome). The secondary outcomes are that the patients in the intervention group will have 1. increased knowledge of CRC screening options and the benefits and risks of these options; 2. increased SDM engagement; and 3. find the DA acceptable. Investigators also anticipate that at least 50% of eligible participants will choose to participate in the study.

本研究针对一款新开发的结直肠癌筛查（colorectal cancer screening, CRC）决策辅助工具（decision aid, DA）开展可行性试点随机对照试验（randomized controlled trial, RCT），共招募66名来自社区卫生中心的76~85岁LHL成年人。研究假设如下：干预组患者的筛查意向更易发生改变，具体体现为——预期寿命<10年的患者、以及预期寿命>10年但无结直肠癌风险因素的意向筛查人群占比降低，而预期寿命>10年且存在结直肠癌风险因素、或从未接受过筛查的意向筛查人群占比升高（主要结局指标）。次要结局指标包括：1. 干预组患者对结直肠癌筛查方案及其获益与风险的认知水平显著提升；2. 患者的共享决策（shared decision making, SDM）参与度增加；3. 受试者对该决策辅助工具的接受度良好。研究者同时预期，至少50%的符合入组资格的参与者将选择参与本研究。
