Ambulatory safety nets (ASNs) employ a combination of approaches (e.g., patient navigators, care coordination, patient education, workflow redesigns) to enhance the safety of patients receiving outpatient care. This article describes the design and execution of a colorectal cancer (CRC) ASN to identify patients a previous abnormal CRC screen (documentation of a previous positive at-home CRC screening or overdue surveillance colonoscopy) and facilitate completion of follow-up testing. Among patients identified between October 2022 - February 2024, 40% were scheduled for a colonoscopy and 29% completed screening.
