Abstract

Background and aims: Non-pharmacological interventions to improve patient-reported outcomes of colonoscopy may be effective at mitigating negative experiences and perceptions of the procedure, but research to characterise the extent and features of studies of these interventions is limited.

Methods: We conducted a scoping review searching multiple databases for peer-reviewed publications of randomised controlled trials conducted in adults investigating a non-pharmacological intervention to improve patient-reported outcomes of colonoscopy. Study characteristics were tabulated and summarised narratively and graphically.

Results: We screened 5939 citations and 962 full texts, and included 245 publications from 39 countries published between 1992 and 2022. Of these, 80.8% were full publications and 19.2% were abstracts. Of the 41.9% of studies reporting funding sources, 11.4% were unfunded. The most common interventions were carbon dioxide and/or water insufflation methods (33.9%), complementary and alternative medicines (eg, acupuncture) (20.0%), and colonoscope technology (eg, magnetic scope guide) (21.6%). Pain was as an outcome across 82.0% of studies. Studies most often used a patient-reported outcome examining patient experience during the procedure (60.0%), but 42.9% of studies included an outcome without specifying the time that the patient experienced the outcome. Most intraprocedural patient-reported outcomes were measured retrospectively rather than contemporaneously, although studies varied in terms of when outcomes were assessed.

Conclusion: Research on non-pharmacological interventions to improve patient-reported outcomes of colonoscopy is unevenly distributed across types of intervention and features high variation in study design and reporting, in particular around outcomes. Future research efforts into non-pharmacological interventions to improve patient-reported outcomes of colonoscopy should be directed at underinvestigated interventions and developing consensus-based guidelines for study design, with particular attention to how and when outcomes are experienced and measured.

非药物干预改善患者结肠镜检查结果的随机对照试验:范围回顾。
背景和目的:改善患者报告的结肠镜检查结果的非药物干预可能有效地减轻对该手术的负面体验和看法,但对这些干预研究的程度和特征的研究是有限的。方法:我们进行了一项范围综述,在多个数据库中检索同行评议的随机对照试验的出版物,这些试验在成人中进行,研究非药物干预以改善患者报告的结肠镜检查结果。将研究特征制成表格,并以叙述和图形方式进行总结。结果:我们筛选了5939篇引文和962篇全文,包括了1992年至2022年间出版的来自39个国家的245篇出版物。其中80.8%为全文,19.2%为摘要。在报告资金来源的41.9%的研究中,11.4%没有得到资助。最常见的干预措施是二氧化碳和/或水注入法(33.9%),补充和替代药物(如针灸)(20.0%)和结肠镜技术(如磁力镜引导)(21.6%)。在82.0%的研究中,疼痛被作为结果。研究最常使用患者报告的结果来检查患者在手术过程中的经历(60.0%),但42.9%的研究包括没有指定患者经历结果的时间的结果。大多数术中患者报告的结果是回顾性测量的,而不是同时测量的,尽管研究在评估结果的时间方面有所不同。结论:改善结肠镜检查患者报告结果的非药物干预研究在不同类型的干预中分布不均匀,研究设计和报告的差异很大,特别是在结果方面。未来对改善患者结肠镜检查结果的非药物干预措施的研究应针对未充分调查的干预措施,并制定基于共识的研究设计指南,特别注意如何以及何时体验和测量结果。普洛斯彼罗注册号:42020173906。
