Patient Education Regarding Fasting Recommendations to Shorten Fasting Times in Patients Undergoing Esophagogastroduodenoscopy: A Controlled Pilot Study.
Harm H J van Noort, Carlijn R Lamers, Hester Vermeulen and 2 others
PMID 35856722WHAT IT FOUND
A bundled nurse-delivered fasting education package was linked to shorter fasting, better comfort and a clearer endoscopic view, but lower satisfaction with preparation care.
Key findings
01A bundled education package (rationale, timetable, leaflet, infographic and meal suggestions) was associated with shorter fasting: solid-food fasting averaged 9:31 hours in the education group versus 12:56 hours in routine care, and clear-liquid fasting averaged 5:03 versus 10:26 hours.
02The endoscopic view favoured the education group: gastric residual volume was lower, total Mucosal Visibility Score was lower, and the endoscopist rated ability to judge the mucosa higher.
03Educated patients reported less overall discomfort, with less thirst and hunger and no pre-procedure vomiting, but they rated preparation care 0.56 points lower on a 0 to 10 scale.

What it does not show
Patients were not randomly assigned, so other differences between groups could explain the results. This was a feasibility pilot, not a study designed to prove effectiveness. The intervention was a bundle, so the contribution of any single component cannot be separated. Patients chose their own last meals and drinks, and the study did not correct for prokinetic medication, both of which can affect stomach visibility. Education used Dutch telephone and written materials, so it may not work for people who are illiterate, cannot read Dutch or are not native speakers. Satisfaction was based only on returned questionnaires, and response rates differed between groups. People with bariatric surgery, diabetes, gastroparesis or no swallow reflex were excluded, so results may not apply to them.
The easy way to misread this
Do not conclude that any single part of the education package caused shorter fasting and better endoscopic view. The intervention combined rationale, a timetable, written materials, an infographic and meal suggestions, and patients were not randomly assigned.
