Direct Mail Programs Work… But Will Health Centers Implement Them? Findings from STOP CRC
Pragmatic clinical trial; STOP CRC; Colorectal cancer; Direct mail; Clinical research
- Strategies and Opportunites to Stop Colorectal Cancer in Priority Populations (STOP CRC) looked at the effect of direct mail fecal testing for patients due for colorectal cancer screening.
- Kaiser Permanente’s Thrive program mails more than 500,000 test kits annually, with over 60% completed and returned.
- In STOP CRC, a cluster-randomized pragmatic trial, researchers identified eligible patients for each of three intervention steps: an introduction letter, a testing kit, and a reminder postcard.
- Completion of colorectal cancer screening was higher in intervention groups than usual care, in both primary and lagged datasets, with the highest rates seen in clinics that sent reminder cards.
A lagged data set was an ad hoc addition when the researchers realized that many clinics faced delays and what looked like Year 2 screenings were actually Year 1.
Findings from STOP CRC confirm the major challenge of bridging the gap between efficacy studies and effectiveness studies.
In reflecting on implementation, a second pilot might have helped ensure that sites were properly equipped to handle the requirements of mass printing and mailing needed for test kits.
