NCT06551883

Brief Summary

The goal of this quasi-experimental study was to compare the effect of single-dose and split-dose 3L compound polyethylene glycol electrolyte powder (PEG) regimen on the quality, comfort and tolerability of bowel preparation in patients who would undergo colonoscopy examination or treatment. Participants in group A received a split-dose 3L PEG regimen, with 1L PEG taken on the night before the colonoscopy and 2L PEG taken 4-6 hours before the procedure. Participants in group B received a single-dose 3L PEG taken 4-6 hours before the colonoscopy.

Outcome Measures

Primary Outcomes (3)

  • Bowel preparation quality

    Bowel preparation quality was evaluated by the Boston Bowel Preparation Scale (BBPS)

    The BBPS scores were filled out by the treating physician in the designated area on the patient's examination request form and were collected and organized by the research team immediately after the end of the day's clinic

  • comfort

    a self-designed comfort evaluation scale was used, with a linear visual analog rating scale ranging from 0 (comfortable) to 4 (extremely uncomfortable).

    Patients self-evaluated their comfort level during the bowel preparation process after it was completed

  • tolerability

    ①Patients self-assessed whether they were willing to undergo the same bowel preparation method again after the end of bowel preparation; ②Patients self-evaluated the difficulty of completing the bowel cleansing process after bowel preparation, with a score of very difficult (1 point), difficult (2 points), moderate (3 points), easy (4 points), and very easy (5 points)

    Patients finished the tolerability evaluation by themselves after completing bowel preparation and before being sent to the endoscopy center

Secondary Outcomes (2)

  • sleep quality

    Patients finished the sleep quality evaluation by themselves after completing bowel preparation and before being sent to the endoscopy center

  • adherence

    Patients finished the adherence evaluation by themselves after completing bowel preparation and before being sent to the endoscopy center

Study Arms (2)

Group A

PLACEBO COMPARATOR

Patients in group A were given the 3L PEG in two doses: 1L of PEG was taken from 8:00 pm to 9:00 pm on the night before the examination, and the remaining 2L of PEG were taken from 4:00 am to 6:00 am on the day of the examination, with 250 mL taken every 15 minutes until finished.

Procedure: traditional bowel preparation regime

Group B

EXPERIMENTAL

Patients in group B were given 3L of PEG in a single dose, which was taken gradually from around 3-4 am, 4-6 hours before the examination. Patients in group B were also instructed to take 250 mL every 15 minutes until the 3L were finished.

Procedure: different bowel preparation regime

Interventions

Patients in Group B receive the 3L of PEG in a single dose

Group B

Patients in Group A receive the 3L of PEG in a split dose

Group A
