Background: Colorectal cancer is the third leading cause of cancer-related deaths in Taiwan. Patients diagnosed early have excellent cure rates. Mackay Memorial Hospital, working on a Bureau of Health Promotion (BHP) project, found the colorectal cancer screening completion rate for positive patients to be the lowest among four cancer screen¬ings reviewed. We thus formed a project team to improve the follow-up completion rate for colorectal cancer screen¬ing-positive patients. Purpose: T his project was designed to raise the follow-up completion rate for colorectal cancer screening-positive pa-tients to 65%. Methods: Explicit interventions implemented included making health education leaflets and return visit reminder sheets, holding/organizing screening seminars, opening a consultation helpline, formulating follow-up colorectal can¬cer screening procedures for screening-positive patients, holding hospital educational training courses, establishing cross-unit collaboration models, and benchmarking other hospitals. Results: The follow-up completion rate increased from 53.63% to 66.08%. Conclusions: Conducting health education programs and strengthening team awareness of follow-up completion rates effectively enhanced the follow-up completion rate for colorectal cancer screening-positive patients and improved medical care quality.
