- In a Danish population invited for colorectal cancer (CRC) screening, dissemination of reminders generally reduced demographic participation inequalities but increased socioeconomic participation inequalities.
Why this matters
- Evidence suggests that the use of reminders for CRC screening may help to overcome socioeconomic and demographic impediments to participation.
- Study to investigate the effect of socioeconomic and demographic factors on participation in 763,511 individuals invited for CRC screening between 2014 and 2015.
- Data source: Danish Colorectal Cancer Screening Database.
- Funding: None disclosed.
- 50.70% underwent CRC screening following initial invitation.
- Reminders were sent to 376,395 individuals, among whom 35.46% subsequently underwent CRC screening.
- Reminders reduced differences in participation by demographic factors; regarding age, for example:
- OR for nonparticipation among participants aged >70 years (vs
- Differences in participation by socioeconomic status were increased following dissemination of reminders; regarding income quartile, for example:
- OR=0.54 (95% CI, 0.53-0.55) for nonparticipation in those in the fourth quartile of income (vs first quartile) at initial invitation vs 0.44 (95% CI, 0.43-0.45) after reminder.
- Retrospective data.
