Summary
Brief summary (as posted)
Colorectal cancer (CRC) is one of the major global health challenges. CRC is currently the third most common cancer in men and the second common in women worldwide, accounting for approximately 10% of all cancers. Randomized controlled studies have shown that CRC screening using Faecal Occult Blood Testing (FOBT) is effective in reducing cancer mortality by 15-33%. Since yearly testing is recommended to maintain programmatic effectiveness, longitudinal adherence is a critical component of FOBT-based screening programs. The investigators previous study conducted in Hong Kong showed that the rate of compliance with CRC screening was declining since the first year of enrolment. Nevertheless, it remains unknown whether interventions based on reminder systems could effectively enhance longitudinal compliance with FOBT, especially among those who have already enrolled in a CRC screening programme. Current evidence does not adequately compare whether interactive or one-way reminder messages are superior to usual care (i.e. no reminders).
