Effect of print reminder on colorectal cancer screening in a community setting: A randomized controlled study

ABSTRACT: Interventions: In the intervention group 1, the printed reminder is mailed to the participants’ house from local government in December, 2012, in order to inform (a)they are due for screening, (b) morbidity of colorectal cancer, (c) 5-year survival rate by stage, (d) screening procedure. In the intervention group 2, the printed reminder is mailed to the participants’ house from local government in December, 2012, in order to inform (a) they are due for screening, (b) morbidity of colorectal cancer, (c) 5-year survival rate by stage, (d) screening procedure, (e) importance of repeated screening, (f) positive predictive value of colorectal cancer screening. Although no reminder is delivered to the control group, control group is exposed to routine publicity campaigns that inform the residents about the colorectal cancer screening program by the local government through its website and monthly government newsletter. Primary outcome(s): Colorectal Cancer screening rate Study Design: Factorial Randomized

Project description:The aim of the trial is to test the effect of a web-based decision aid (DA) on colorectal cancer (CRC) knowledge, decisional conflict, participation rate, and informed choice (evaluated based on knowledge, attitudes and actual participation). The study includes three study arms. Citizens to be recruited are identified from the Danish Civil Registration System based on residence (Central Denmark Region), age (50-74 years old), and month of birth. A random sample of 15,000 citizens born in December (invited for CRC screening through October/November/December 2017) (study arm 1+2) and 5,000 citizens born in October (invited for CRC screening in January/February 2017) (study arm 3) is identified. Citizens in study arm 1+2 will receive a baseline questionnaire assessing knowledge, attitudes, worry, and health literacy. Non respondents will receive one reminder after two weeks and after four weeks non-respondents will receive a phone call, offering them to fill out the questionnaire via the phone. Baseline questionnaire respondents are included in the study, and will be randomized into two study arms (intervention group and control group). Citizens in the intervention group will be identified in the screening IT system. Date of screening invitation and screening reminder (citizens who do not return a stool sample within 45 days of the screening invitation) is retrieved. Citizens receiving a screening reminder will receive a link for the DA. Follow-up questionnaire will be sent to all included citizens in study-arm 1+2 three months after the last screening invitation has been sent out. Citizens have six weeks to respond to the questionnaire. Study arm 3 is a historic cohort. The citizens receive only one questionnaire at the same time as the baseline questionnaires are sent out to the intervention and control groups. The citizens are included if they respond to the questionnaire within six weeks. Questionnaire reminders are sent out at two and four weeks. Data on screening invitation date, screening reminder date, returning a stool sample and result will be retrieved from the screening IT system for all included citizens (Study arm 1-3). Lastly, data from Statistics Denmark (on socio-demographic and socio-economic factors) will be included.
