Think-aloud testing of a companion app for colonoscopy exams: usability study

Colonoscopies are vital for initial screening, follow-ups, surveillance of neoplasia, and assessing symptoms like rectal bleeding. Successful colonoscopies require thorough colon preparation, but up to 33% fail due to poor preparation. This can lead to longer procedures, repeat colonoscopies, inconvenience, poorer health outcomes, and higher costs. eHealth tools can enhance bowel preparation and potentially reduce the need for repeat procedures. This usability study aimed to identify strengths and weaknesses in a prototype companion app for colonoscopy exams. The objective was to obtain in-depth insights into the app's usability, ease of use, and content comprehension, with the objective of refining the tool to effectively fulfil its intended purpose, guided by feedback from potential users.
