Reminders on electronic medical record (EMR) have been identified as a low-cost and high-reach strategy to increase participation. The population-based colorectal cancer screening program in the city of Barcelona is aimed at men and women between ages 50 and 69 involving immunochemical fecal occult blood test (iFOBT) every 2 years. Community pharmacies participating in the program are in charge of delivery and collection of iFOBT.
