• 1 other identifier: CCHS-QIP-SECOND-FIT-KIT
• Study Type: interventional

Brief Summary

This study aims to assess whether sending patients in a county health care system additional FIT Kits can increase the FIT Kit return rate enough to warrant the extra cost. To do this, the health system mailed a random subset of patients ages 60 to 75 a FIT Kit in November 2024 in addition to sending patients an annual FIT Kit mailing. This work analyzes the return rate of mailed FIT Kits within 60-days of the November mailing.
