- Original description
Colorectal cancer is a leading cause of mortality in Catalonia. Although early detection programs using the fecal immunochemical test (FIT) are effective in reducing both incidence and mortality, their success relies on high population participation. Currently, in the Vallès Occidental region, the participation rate stands at 42%, which is below the 65% minimum recommended by European health authorities. The objective of this randomized controlled trial is to evaluate whether sending a reminder text message (SMS) is an effective tool to increase participation in the screening program. The study will include 10,084 participants aged between 50 and 69 years. Half of the participants will receive a reminder SMS five weeks after their initial invitation, while the other half will follow the standard of care involving postal letters. Researchers anticipate that this strategy will not only increase the number of individuals undergoing screening but also shorten the response time and reduce the need for sending postal remindersRead full original descriptionShow less
