Effect of nurse-performed enhanced patient education on colonoscopy bowel preparation quality.
Gamze Arslanca, Mahmure Aygün
PMID 35976357WHAT IT FOUND
Nurse-performed enhanced education before colonoscopy, using face-to-face teaching, visual presentation, a booklet with pictures and reminder calls, produced adequate bowel preparation in 80% of patients versus 69.2% with a routine leaflet.
Key findings
01Adequate bowel preparation was higher in the enhanced education group than in the leaflet group: 80% versus 69.2% (p = 0.031).
02Mean bowel cleanliness score was higher after enhanced education, 6.76 versus 5.56 on a 0-9 scale (p = 0.000).
03Cecal intubation was completed more often after enhanced education than with the leaflet: 80% versus 67.3% (p = 0.012).

What it does not show
Single-center study in one Turkish colonoscopy unit, so results may not apply to other settings. Patients were not randomly assigned; the medical secretary divided them consecutively by appointment order. Groups were not fully balanced: more intervention patients waited less than two weeks for colonoscopy (26% versus 5.8%, p = 0.000), and body mass index differed (p = 0.037). The intervention was a bundle of face-to-face teaching, visual presentation, a booklet with pictures and reminder calls, so the study cannot identify which component mattered. One researcher was a full-time colonoscopy nurse, delivered the education, assisted the procedures and recorded data, which could affect patient behaviour or data collection despite endoscopist blinding. Patients and nurses were not blinded to group. The study excluded people with previous abdominal surgery, active lower gastrointestinal bleeding or cognitive impairment, and only enrolled first-time colonoscopy patients. No comparison was made of workload or costs.

The easy way to misread this
Do not conclude that nurse education alone, or any single part of it, caused the improvement, and do not read the higher biopsy rate as proof of better polyp detection. The intervention included face-to-face teaching, visual presentation, a booklet with pictures and reminder calls together; polyp detection did not differ significantly (36% versus 26.8%, p = 0.084).
