1-L Prep Boosts Quality, Not Adequacy
Randomized trial in hospitalized patients found improved high-quality bowel cleansing with 1-L regimen, though primary endpoint differences were not statistically significant
To compare the effectiveness of 1-L polyethylene glycol-ascorbate bowel preparation against 2-L and 4-L PEG-ascorbate specifically in hospitalized adults undergoing elective colonoscopy.
Key Findings:
Adequate cleansing rates were similar across groups: 82% (1 L), 78% (2 L), 79% (4 L).
High-quality cleansing occurred more often with 1-L regimen (47%) compared to 2-L (35%) and 4-L (37%).
Willingness to repeat preparation was highest in the 1-L group (84%).
Vomiting was more frequent with the 1-L regimen (15%) compared to 2-L (7%) and 4-L (11%).
Polyp detection rates were 31% (1 L and 4 L) and 23% (2 L).
Interpretation:
The 1-L PEG-ascorbate preparation resulted in higher quality bowel cleansing without compromising adequate cleansing rates, suggesting it may be a preferable option for hospitalized patients.
Limitations:
The study was underpowered due to not reaching the planned enrollment of 846 patients, which limits the reliability of the primary endpoint findings.
Findings for the primary endpoint should be interpreted cautiously due to the study's design limitations.
The trial excluded patients undergoing urgent colonoscopy or with severe conditions, which may limit the generalizability of the results to broader populations.
Conclusion:
In hospitalized adults undergoing elective colonoscopy, 1-L PEG-ascorbate yielded higher rates of high-quality cleansing with similar adequate cleansing rates and high willingness to repeat, though these findings should be interpreted in light of the study's limitations.
