Patient experiences of colon capsule endoscopy:a qualitative study

Background: Colon capsule endoscopy (CCE) was introduced by NHS England at scale during the COVID-19 pandemic to support colorectal diagnostics recovery. However, little was known about the patient experience of CCE. Objective: To explore the experiences of CCE during the NHS England pilot, to better understand what a patient-centred service for the future should look like. Design: A qualitative study to explore the patient and clinician experiences of CCE. Methods: Focus group discussions (n=25 participants) and semi-structured interviews (n=7), selected purposively on the basis of maximum variation, generated qualitative material exploring patient understanding, preferences and experiences. To place their experiences in context, we conducted asynchronous focus group discussions with clinicians (n=16). Analysis was thematic. Results: Most patients valued CCE’s convenience and would repeat it, although for some their experiences would deter them from having the procedure again. Anxieties included fear when swallowing the capsule; concerns about it becoming stuck and/or whether the recording was working; what to do when the capsule was inside them; and worries about the novelty of the treatment. Women expressed greater discomfort, pain and anxieties during bowel preparation and the procedure than men. Participants highlighted the need for a more balanced description of the procedure than indicated in information leaflets and videos. They particularly felt the possibility of further investigations could be better explained. Healthcare professionals may underestimate patient concerns. Conclusion: CCE has the potential to expand colorectal diagnostic capacity but requires patients to be well informed and supported throughout the process. Gender differences in experiences of CCE are notable and could be partially addressed by providing more specific information, consistent with women’s experiences.
