METHODS: Adults were recruited from 444 US community gastrointestinal practices and provided a kit number for enrollment into an online survey to be completed within 2 weeks. Survey questions evaluated colonoscopy history and prior bowel preparation(s) prescribed, patient experience during NER1006 administration, and patient satisfaction with the bowel preparation process. A 9-point predefined grading scale was used to evaluate ease of NER1006 preparation and consumption (range, 1 "very difficult" to 9 "very easy"); the perceived importance of volume requirement and clear liquid options (range, 1 "not important at all" to 9 "very important"); and patient satisfaction (range, 1 "not satisfied at all" to 9 "very satisfied").

RESULTS: 1630 patients were enrolled, 1606 underwent colonoscopy, and 1598 completed the survey between September 15, 2018 and February 28, 2019. Among 1606 patients who had a colonoscopy, 62.5% were female, and the mean patient age was 54.4 years (range 18-89 years). Most patients (74.7%) did not report a family history of colon cancer, 62.6% had undergone prior colonoscopy, and 64.8% were undergoing colonoscopy for routine colorectal cancer screening. A majority (76.1%) of patients who completed the survey reported that NER1006 was very easy to prepare and take, and 89.9% were very or moderately satisfied with NER1006 overall. Most (97.6%) patients reported consuming all or most of the bowel preparation. Among 1005 patients with previous bowel preparation use, 84.7% indicated that their experience with NER1006 was much better or better (65.3%) or about the same (19.4%) compared with previously used bowel preparations, while only 15.3% rated NER1006 as worse or much worse.

CONCLUSIONS: In this first real-world, US multicenter survey, patient-reported experience with NER1006 as a bowel preparation for colonoscopy was favorable and adherence was high. The majority of patients were very or moderately satisfied with the overall experience and found it much better/better than previously used bowel preparations.
