Our study aimed to determine, for patients who had undergone recent colonoscopy, associations between specific colonoscopy patient characteristics, exam characteristics and patients' perception of colonoscopy reducing their risk of dying from colorectal cancer. A cross-sectional analysis was conducted using data (2004-2008) from the New Hampshire Colonoscopy Registry, consisting of a Self-report Questionnaire, Colonoscopy Report form, and a Follow-up Questionnaire, which measured agreement responses to the statement, "Having a colonoscopy decreased my chances of dying from colon cancer". Chi-square tests and logistic regression were used to assess differences in patient responses by patient and colonoscopy characteristics. A majority of patients (N=5,672, 81%) agreed that having a colonoscopy decreased their chances of dying from colon cancer. Patients with a personal history of polyps were more likely to agree that colonoscopy reduced their chances of dying compared to patients without prior polypectomy [OR (95% CI) =1.34 (1.06, 1.69)] and patients with a family history of colorectal cancer were 33% more likely to agree to the statement than those without a family history [OR (95% CI) =1.33 (1.12, 1.58)]. Personal history of polyps and family history of colorectal cancer are significant predictors of patients' positive perception of colonoscopy, suggesting that personal experience, rather than the potential preventive effect of colonoscopy itself, may influence the perceived benefit of colonoscopy. Intervention efforts should be made to effectively disseminate knowledge of the preventive benefit of colonoscopy.
我们的研究旨在确定在最近接受过结肠镜检查的患者中，特定的结肠镜检查患者特征、检查特征以及患者对结肠镜检查降低其死于结直肠癌风险的认知之间的关联。使用新罕布什尔州结肠镜检查登记处的数据（2004-2008 年）进行了横断面分析，这些数据包括一份自我报告问卷、结肠镜检查报告表和一份随访问卷，该问卷测量了对“进行结肠镜检查降低了我死于结肠癌的几率”这一说法的一致应答率。卡方检验和逻辑回归用于评估患者对检查特征的应答差异。大多数患者（N=5672，81%）同意进行结肠镜检查降低了他们死于结肠癌的几率。与未行息肉切除术的患者相比，有息肉病史的患者更有可能同意结肠镜检查降低了他们死于结肠癌的几率[比值比（95%置信区间）=1.34（1.06，1.69）]，而有结直肠癌家族史的患者比没有家族史的患者更有可能同意该说法[比值比（95%置信区间）=1.33（1.12，1.58）]。有息肉病史和结直肠癌家族史是患者对结肠镜检查的积极认知的重要预测因素，这表明个人经验而不是结肠镜检查本身的潜在预防效果可能会影响对结肠镜检查的认知获益。应该努力进行有效的干预，以传播对结肠镜检查预防益处的知识。
