The clinical evidence behind VeriPrep.

Structured digital guidance improves bowel preparation quality. Better preparation improves detection. Better detection saves lives. Here's the published research.

How digital guidance leads to better outcomes.

1

Structured guidance improves prep quality

Technology-based bowel preparation instructions improved adherence by 20% compared to standard care across 47 randomized controlled trials.

2

Better prep means fewer missed lesions

Inadequate bowel preparation is associated with a 47% reduction in early adenoma detection and a 26% reduction in advanced adenoma detection.

3

Better detection means better outcomes

Colonoscopy screening is associated with up to a 62% reduction in colorectal cancer mortality — but only when preparation quality allows complete visualization.

Meta-analysis of 29 studies

Key published studies.

PERICLES-II — Walter et al., 2019

SMS reminders cut inadequate prep rates in half

Patients who received SMS-based preparation reminders had significantly lower rates of insufficient bowel preparation: 9% versus 19% in the control group. Mean bowel preparation quality scores were also significantly higher in the SMS group across all colon segments.

Solonowicz et al., 2022

Digital navigation cut no-show rates from 14% to 8%

A randomized trial of 1,625 patients found that SMS-based digital navigation reduced colonoscopy no-show rates from 14% to 8% and improved adequate bowel preparation from 88% to 93% for screening colonoscopies.

Wonggom et al., 2023

47 randomized trials: technology-based instructions improved compliance by 20%

A systematic review of 47 randomized controlled trials found that technology-based bowel preparation instructions — including mobile apps, SMS, video, and web-based education — improved adherence to preparation instructions by 20% compared to standard care.

Pantaleon et al., 2022

Inadequate prep misses nearly 7 in 10 adenomas

A prospective multicenter study found a per-adenoma miss rate of 68.9% in patients with inadequate bowel preparation who underwent early repeat colonoscopy. Poorly cleaned colon segments harbored the majority of missed advanced adenomas and all missed cancers in the study.

Guo et al., 2020

Reinforced education improved adequate prep from 74% to 87%

A meta-analysis of 18 randomized trials with 6,536 patients found that reinforced patient education — including structured guidance and reminders — improved adequate bowel preparation from 74% to 87%. Diet compliance also increased from 83% to 91%.
