Bowel preparation is the basis of colonoscopy, and adequate bowel preparation is essential to the success of colonoscopy. Studies have been reported that telephone intervention can improve the quality of bowel preparation, while it remains unclear regarding effectiveness with the elderly. The purpose of this study was to evaluate the effect of telephone intervention on the quality of bowel preparation for colonoscopy in elderly outpatients. In total, 162 outpatients older than 65 years were enrolled and randomly divided into a control group and a study group. Patients in the study group were re-educated through telephone by a specific nurse 2 days before colonoscopy, whereas participants in the control group received education only on the day of appointment. The Ottawa score was used to evaluate the quality of bowel preparation between the two groups. In this study, no significant differences were observed in age, gender, body mass index, educational level, smoking and/or alcohol drinking, waiting time to colonoscopy, reasons for colonoscopy, and colonoscopic findings between the control group and the study group. Participants in the study group had higher adequate bowel preparation and compliance than the control group (83.1% vs. 59.5%, p = .03; 96.4% vs. 74.7%, p < .001). Univariate analysis showed that only noncompliance with start time was significantly associated with satisfactory bowel preparation in elderly patients. In conclusion, telephone intervention 2 days before colonoscopy can improve the quality of bowel preparation in the elderly.
肠道准备是结肠镜检查的基础，充分的肠道准备对于结肠镜检查的成功至关重要。有研究报道，电话干预可以提高肠道准备的质量，但对于老年人的效果尚不清楚。本研究旨在评估电话干预对老年门诊患者结肠镜检查肠道准备质量的影响。共纳入 162 名年龄大于 65 岁的门诊患者，并随机分为对照组和研究组。研究组患者在结肠镜检查前 2 天由特定护士通过电话进行再教育，而对照组患者仅在预约当天接受教育。采用渥太华评分评估两组肠道准备质量。在本研究中，对照组和研究组在年龄、性别、体重指数、教育水平、吸烟和/或饮酒、结肠镜检查等待时间、结肠镜检查原因和结肠镜检查结果方面无显著差异。研究组患者的肠道准备充分率和依从性均高于对照组（83.1%比 59.5%，p =.03；96.4%比 74.7%，p <.001）。单因素分析显示，只有不遵守开始时间与老年患者的肠道准备充分显著相关。总之，结肠镜检查前 2 天的电话干预可以提高老年人的肠道准备质量。
