Interactive Telehealth Intervention to Increase Longitudinal Adherence to Repeat Faecal Immunochemical Test Screening
Sponsor: Chinese University of Hong Kong
Summary
In Hong Kong, Colorectal cancer ranks second in both cancer incidence and mortality. The government-subsidized population-based CRC screening program (the Program) was launched for asymptomatic individuals aged 50-75 years to undergo biennial FIT screenings. A subsidized follow-up colonoscopy is offered to participants with positive FIT results. Participants are advised to repeat the FIT screening 2 years after receiving a negative result. An automated noninteractive short message service (SMS) text reminder, used by the Program as standard care (SC), is delivered to participants who are due for repeat FIT. According to unpublished data, despite SC, only 34% of participants adhere to biennial repeat FIT in the CRC screening program. Nonadherence to repeat FIT screening is caused by forgetfulness and is associated with an individual's psychological health behaviour.

TI group
CRC screening is arranged by referring the participants to the government-subsidized population-based CRC screening program. Our center is a PCP clinic offering FIT screenings under the Program. Colonoscopy is arranged if the FIT result is positive. Participants are instructed to repeat FIT at any PCP clinic 2 years after receiving a negative result. Based on the 34% local FIT screening adherence rate under SC and the assumption of improved FIT adherence to 49% after interactive TI, a minimum sample size of 332 subjects (166 per group) is required to achieve a statistical significance of p\<0.05 and power of 80%. Assuming that 10% of the subjects will drop out, be lost to follow-up, or have incomplete chatbot conversations, the required sample size is rounded up to 370 (185 per group)
