Brief Summary

High cancellation rates and suboptimal bowel preparation increase patient discomfort, drive economic waste, and compromise clinical outcomes. Despite guideline emphasis on adequate preparation quality, there is no standard on how or when instructions should be delivered. This study compares three common patient education modalities-usual care verbal counseling, written tri-lingual pamphlet, and visual media via smartphone QR code-to determine which yields the best bowel preparation quality as assessed by the Boston Bowel Preparation Scale (BBPS) in an outpatient endoscopy setting.

Conditions

Colonoscopy; Bowel Preparation Quality; Patient Education Materials

Keywords

bowel preparation quality; colonoscopy; Boston Bowel Preparation Scale; patient education; video-based intervention; written educational materials; polyp detection; endoscopy quality

Outcome Measures

Primary Outcomes (1)

• Adequate Bowel Preparation on Boston Bowel Preparation Scale (BBPS)

  Primary outcome dichotomized as adequate versus inadequate bowel preparation. Adequate = total BBPS score ≥6 with all three colon segments (left, transverse, right) scoring ≥2 each (scale 0-3 per segment; range 0-9). Inadequate = total \<6 or any segment \<2. Assessment performed before any bowel cleansing/lavage.

  On day of colonoscopy procedure, assessed immediately upon colonoscope insertion before lavage (time point: 0 minutes)

Secondary Outcomes (9)

• Polyp Detection Rate

  During colonoscopy procedure

• Cecal Intubation Time

  During colonoscopy procedure

• Colonoscopy Withdrawal Time

  During colonoscopy procedure

• Procedure Cancellation Rate

  On day of scheduled colonoscopy

• Repeat Colonoscopy Rate

  Within 6 months of initial colonoscopy

Study Arms (3)

Usual Care (Verbal Counseling)

ACTIVE COMPARATOR

Standard physician/nurse-delivered verbal instructions and standard pharmacy information sheet for bowel preparation solution (split-dose PEG 3L, Fortrans) according to hospital protocol. Timing and dietary guidance aligned with standard of care. No additional written or visual materials provided.

Behavioral: Verbal Counseling

Written Educational Pamphlet

EXPERIMENTAL

Tri-lingual (Malay, English, Chinese) plain-language educational pamphlet detailing step-by-step bowel preparation instructions, plus brief verbal explanation. Pamphlet reviewed by health literacy expert prior to use. Same preparation solution and regimen as Control arm.

Behavioral: Tri-lingual Educational Pamphlet

Visual Media (QR Code Video)

EXPERIMENTAL

Short, structured instructional videos accessible via smartphone QR code explaining bowel preparation procedure step-by-step, plus brief verbal explanation. Videos reviewed by health literacy expert prior to use. Same preparation solution and regimen as Control arm.

Behavioral: QR-Linked Instructional Videos

Interventions

Verbal Counseling BEHAVIORAL

Standard verbal instructions delivered by physician or nurse regarding bowel preparation regimen, timing, dietary restrictions, and what to expect during procedure.

Usual Care (Verbal Counseling)

Tri-lingual Educational Pamphlet BEHAVIORAL

Structured written educational material in Malay, English, and Chinese languages detailing complete bowel preparation instructions, timing, dietary guidance, what to expect, and troubleshooting tips. Provided to participant with brief verbal explanation.

Written Educational Pamphlet

QR-Linked Instructional Videos BEHAVIORAL

Short, professionally produced instructional videos accessible via smartphone QR code link. Videos present step-by-step bowel preparation instructions, timing, dietary guidance, common concerns, and what to expect during procedure. Participant scans QR code to access video(s) on their smartphone.

Visual Media (QR Code Video)
