Optimal bowel preparation is one of the major cornerstones for quality of colonoscopy. But poor bowel preparation still occurs in 10% to 25% of all patients. To optimize patient guidance, we developed a new smartphone app (ColoprAPP) for Android smartphones which guides and accompanies the patient starting 4 days before colonoscopy throughout the whole colonoscopy preparation procedure.
The objective of this study was to assess the function of a newly developed smartphone app for supporting colonoscopy preparation.
We carried out a prospective feasibility study including 25 patients undergoing outpatient colonoscopy at our hospital. As a control, we retrieved the data of 25 patients undergoing outpatient colonoscopy matching in age, sex, and indication for colonoscopy from our colonoscopy database. Patients were asked to download the smartphone app, ColoprAPP, in addition to being given the regular colonoscopy preparation leaflet. All colonoscopies were performed in the morning after using a split-dose preparation containing a polyethlene glycol-based purgative. The study was designed to test feasibility of the prototype, evaluate grade of bowel cleanliness (Boston bowel preparation scale [BBPS]), and assess patient satisfaction with the app.
The smartphone app use was feasible in all patients. BBPS count as a marker for grade of bowel preparation was significantly higher in the smartphone app-supported group (mean 8.1 [SD 0.3] vs 7.1 [SD 0.4], P=.02). Left (mean 2.8 [SD 0.1] vs 2.4 [SD 0.11], P=.02) and transverse colon (mean 2.8 [SD 0.07] vs 2.4 [SD 0.11], P<.001) revealed significantly higher BBPS counts in the smartphone app-supported group than in controls. Patient satisfaction with a smartphone app-supported colonoscopy preparation was high with an average numeric rating scale score for usefulness of 8.2 (visual analog scale 1-10).
A novel developed smartphone app for reinforced education of bowel cleansing was feasible and led to high BBPS scores and patient satisfaction.

最佳肠道准备是结肠镜检查质量的主要基石之一。但仍有10%至25%的患者肠道准备不佳。为了优化患者指导，我们为安卓智能手机开发了一款新的智能手机应用程序（ColoprAPP），该程序从结肠镜检查前4天开始指导并陪伴患者完成整个结肠镜检查准备过程。
本研究的目的是评估一款新开发的支持结肠镜检查准备的智能手机应用程序的功能。
我们进行了一项前瞻性可行性研究，纳入了25例在我院接受门诊结肠镜检查的患者。作为对照，我们从结肠镜检查数据库中检索了25例年龄、性别和结肠镜检查适应证相匹配的接受门诊结肠镜检查的患者的数据。除了给患者常规的结肠镜检查准备手册外，还要求他们下载智能手机应用程序ColoprAPP。所有结肠镜检查均在早晨进行，使用含聚乙二醇泻药的分剂量制剂。该研究旨在测试原型的可行性，评估肠道清洁程度（波士顿肠道准备量表[BBPS]），并评估患者对该应用程序的满意度。
智能手机应用程序在所有患者中使用可行。作为肠道准备程度指标的BBPS计数在智能手机应用程序支持组中显著更高（平均8.1[标准差0.3]对7.1[标准差0.4]，P = 0.02）。智能手机应用程序支持组的左半结肠（平均2.8[标准差0.1]对2.4[标准差0.11]，P = 0.02）和横结肠（平均2.8[标准差0.07]对2.4[标准差0.11]，P<0.001）的BBPS计数显著高于对照组。患者对智能手机应用程序支持的结肠镜检查准备的满意度较高，有用性的平均数字评分量表得分为8.2（视觉模拟量表1 - 10）。
一款新开发的用于加强肠道清洁教育的智能手机应用程序是可行的，并导致了较高的BBPS评分和患者满意度。
