Sponsored by National Taiwan University Hospital · Not applicable, Interventional, and Screening
The primary objective of this study was to evaluate the impact of a constructed shared decision (SDM) intervention (offering an option between colonoscopy and immunochemical collapsible occult blood testing (fecal immunochemical test; FIT)) on improving the incidence of high colonoscopy stromal in patients aged 40-49 years with a close relative suffering from colorectal cancer, compared to standard care (direct referral for colonoscopy).

Colonoscopy
Diagnostic Test: Colonoscopy
Participants underwent standard colonoscopy performed by experienced endoscopists following routine clinical procedures.
Participants received a shared decision-making intervention including educational materials and discussion with clinicians to choose between screening options.
Colonoscopy screening rate
Completion of colonoscopy within 3 months after randomization, defined as documented completion of colonoscopy or colonoscopy performed after a positive FIT result.
Time frame: Within 3 months after randomization
Patient satisfaction with shared decision-making
Measured using the Shared Decision-Making Questionnaire-9 (SDM-Q-9). The scale ranges from 0 to 100, with higher scores indicating greater decision conflict.
Time frame: Immediately after the SDM consultation visit
Participant choice of screening modality (colonoscopy vs fecal immunochemical test)
Participant choice of screening modality was recorded as either colonoscopy or fecal immunochemical test following the intervention.
Time frame: Immediately after the intervention
Detection rate of colorectal neoplasia
Detection of colorectal neoplasia including adenoma, advanced adenoma, or colorectal cancer.
Time frame: During colonoscopy procedure
