Beverage intake preference and bowel preparation laxative taste preference for colonoscopy.
OBJECTIVE
To examine whether non-alcoholic beverage intake preferences can guide polyethylene glycol (PEG)-based bowel laxative preparation selection for patients.


METHODS
We conducted eight public taste test sessions using commercially procured (A) unflavored PEG, (B) citrus flavored PEG and (C) PEG with ascorbate (Moviprep). We collected characteristics of volunteers including their beverage intake preferences. The volunteers tasted the laxatives in randomly assigned orders and ranked the laxatives as 1(st), 2(nd), and 3(rd) based on their taste preferences. Our primary outcome is the number of 1(st) place rankings for each preparation.


RESULTS
A total of 777 volunteers completed the study. Unflavored PEG was ranked as 1(st) by 70 (9.0%), flavored PEG by 534 (68.7%) and PEG with ascorbate by 173 (22.3%) volunteers. Demographic, lifestyle characteristics and beverage intake patterns for coffee, tea, and carbonated drinks did not predict PEG-based laxative preference.


CONCLUSIONS
Beverage intake pattern was not a useful guide for PEG-based laxative preference. It is important to develop more tolerable and affordable bowel preparation laxatives for colonoscopy. Also, patients should taste their PEG solution with and without flavoring before flavoring the entire gallon as this may give them more opportunity to pick a pattern that may be more tolerable.
