视频宣教用于藏族患者肠道准备的单中心随机对照研究

A single-center randomized controlled trial of video instruction for bowel preparation in the Tibetan patients

摘要:

目的 探讨在肠镜检查前以视频宣教方式指导藏族人群进行肠道准备能否改善肠道准备的质量和提高结肠息肉检出率(Polyp detection rate,PDR)。 方法 采用前瞻性、对内镜医师设盲的随机对照研究设计。纳入2024年3月1日至2024年7月31日在青海省玉树藏族自治州人民医院接受结肠镜检查的患者。随机将患者分为视频宣教组和文字宣教组,采用渥太华评分,比较肠镜检查的质量和PDR,并采用Logistic单因素、多因素分析和亚组分析比较宣教方式和息肉检出率的关系。 结果 共纳入149名患者,其中文字宣教组79人,视频宣教组70人。两组的渥太华评分无明显差异,PDR分别为1.3%和14.3%,两组差异有统计学意义。Logistic单因素分析提示使用视频宣教、横结肠渥太华评分是PDR的危险因素。Logistic多因素分析提示视频宣教是PDR的危险因素,结果在多个模型中稳定。 结论 视频宣教可以提高PDR。

Abstract:

Objective: To investigate whether video-based guidance for colon preparation in Tibetan populations can improve the quality of bowel preparation and increase the Polyp Detection Rate (PDR) during colonoscopy. Methods: A prospective, endoscopist-blind, randomized controlled trial was conducted. Patients who underwent colonoscopy at the Yushu Tibetan Autonomous Prefecture People’s Hospital from March 1, 2024 to July 31, 2024, were enrolled. Patients were randomly divided into two groups: the video-based education group and the text-based education group. The Ottawa Bowel Preparation Score was used to evaluate the quality of colon preparation, and PDR was compared between the two groups. Logistic univariate, multivariate, and subgroup analyses were conducted to examine the relationship between the method of education and PDR. Results: A total of 149 patients were included, with 79 in the text-based education group and 70 in the video-based education group. There was no significant difference in Ottawa scores between the two groups, but the PDR was 1.3% in the text-based group and 14.3% in the video-based group, showing a statistically significant difference. Logistic univariate analysis indicated that video-based education and the Ottawa score for the transverse colon were risk factors for PDR. Logistic multivariate analysis confirmed that video-based education was a risk factor for PDR, with stable results across multiple models. Conclusion: Video-based education can improve PDR in the Tibetan population.
