Marco Antonio Alvarez-Gonzalez et al. Educational nurse-led telephone intervention
shortly before colonoscopy as a salvage strategy after previous bowel preparation
failure: a multicenter randomized trial
This randomized controlled trial investigates the efficacy of a telephone call from
a nurse to reinforce bowel preparation instructions 48 hours before repeat colonoscopy
in patients with previous inadequate bowel preparation. Although the strategy was
not successful overall, per-protocol analysis of patients who were contacted showed
significantly improved bowel preparation.
