Timeliness of Surveillance Colonoscopy in Underserved Populations: Association with Patient Navigation for Initial Screening Colonoscopy

摘要

Patient navigation (PN) improves initial colorectal cancer (CRC) screening in underserved populations. Whether the impact persists and improves the timeliness of follow-up screening colonoscopy (FSC) is not known. Patients receiving PN at initial colonoscopy between 2010-2011 with findings requiring FSC were matched to unnavigated patients requiring FSC. The primary outcome was proportion of patients with timely FSC, defined as colonoscopy within six months of recommendation. Of 216 patients in the study 103 (48) completed FSC: 33 of 62 (53) who received PN compared with 70 of 154 (45) in the control group (p=.3O). After adjusting for insurance, education, language and visits, navigated patients had higher odds (AOR=1.53, 95 CI 0.80-2.92) of timely FSC completion compared with unnavigated patients. Timely FSC completion in under-served patients is low. Patients navigated for initial colonoscopy or not had similar rates of FSC completion. Future studies should investigate navigation for FSC to improve equity in CRC.
