Capsule endoscopy is a novel technique for examining the small bowel; however, data interpretation is time consuming and requires expertise. This study aimed to compare the interpretation of capsule endoscopy between an experienced gastroenterologist and a nurse. A total of 50 consecutive videos were viewed independently by a nurse and a physician, both blinded to the referral indications. The nurse had no prior experience with capsule endoscopy. Possible pathology was graded in a pre-agreed standardized manner, with findings described as "relevant," "uncertain," or "irrelevant." Another gastroenterologist, who had knowledge of all the cases including follow-up data and clinical outcomes, independently arbitrated. Findings showed no difference in the number of relevant or uncertain pathologies identified. The nurse reader was more likely to record irrelevant findings (4.7 vs. 2.0 lesions; p < .01) and required more time to read the videos than the physician (mean = 73 vs. 58 min; p < .01). This study shows that a nurse capsule endoscopy reader is as capable as an experienced physician in identifying small bowel mucosal abnormalities on capsule endoscopy. Capsule endoscopy is an area in which nurses could develop as physician extenders.
胶囊内镜是一种用于检查小肠的新技术；然而，数据解读耗时且需要专业知识。本研究旨在比较经验丰富的胃肠病学家和护士对胶囊内镜的解读。一名护士和一名医生独立观看了连续50段视频，两人均对转诊指征不知情。该护士此前没有胶囊内镜方面的经验。可能的病变按照预先商定的标准化方式分级，结果描述为“相关”、“不确定”或“不相关”。另一名了解所有病例（包括随访数据和临床结果）的胃肠病学家进行独立仲裁。结果显示，在识别出的相关或不确定病变数量上没有差异。护士阅读者更有可能记录不相关的结果（4.7个病变对2.0个病变；p < 0.01），并且比医生阅读视频需要更多时间（平均分别为73分钟和58分钟；p < 0.01）。本研究表明，护士胶囊内镜阅读者在识别胶囊内镜下小肠黏膜异常方面与经验丰富的医生能力相当。胶囊内镜是护士可以作为医生助手发展的一个领域。
