Self-Sampling Tools for Cancer Screening

This randomized controlled trial will evaluate whether evidence-based self-sampling tools improve the cancer screening process among underscreened patients. Participants who are eligible but out-of-date for colorectal cancer screening, cervical cancer screening, or both will be randomized to either usual practice or an intervention that includes mailed self-sampling tools for the appropriate cancer screening test. Primary outcomes include screening initiation (within 12 months of enrollment) and screening completion (within 18 months of enrollment), for each cancer type. Secondary outcomes include repeat screening adherence and receipt of diagnostic resolution following abnormal screening results.
