Brief summary: This is a randomized controlled study to compare the effectiveness of interactive telephone reminders by a layperson on enhancing compliance with CRC screening by FOBT, when compared with usual care (i.e. no intervention).

Detailed description: 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. It leads to 8% of all cancer mortality in the world and it is the fourth most common cause of cancer deaths. There were 4,563 new cases and 3,893 new deaths in Hong Kong in 2012, while 47.4% of the new cases were diagnosed at stage III or above. In the past decades the Asia Pacific countries like China, South Korea, Japan, and Singapore have witnessed a two to three-fold rise in incidence, gradually catching up the figures in Western countries. The direct medical cost for the care of colorectal neoplasia was estimated US$45,115 for stage IV CRC in the initial year of care, bringing a substantial, global public health burden to the healthcare systems.

Randomized controlled studies have shown that CRC screening using Faecal Occult Blood Testing (FOBT) is effective in reducing cancer mortality by 15-33%. FOBT as a quick office-based procedure has the advantages of being non-invasive, inexpensive, acceptable, feasible, patient-friendly and devoid of needs for bowel preparation. A 25% relative risk reduction in CRC mortality was found for those attending at least one round of FOBT screening, according to a systematic review conducted in 2007. Guidelines from the US Preventive Services Task Force, the European Nations, the Asia Pacific Consensus statements and other authorities recommended FOBT as one of the first-line screening modalities, especially in resource-limited regions. Since yearly testing is recommended to maintain programmatic effectiveness, longitudinal adherence is a critical component of FOBT-based screening programs. Our 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 reminder are superior to usual care (i.e. no reminders).
