Abnormal Colorectal Cancer Test Follow-Up: A Quality Improvement Initiative at a Federally Qualified Health Center.

INTRODUCTION/OBJECTIVES: Colonoscopy completion rates after an abnormal fecal immunochemical test (FIT) are suboptimal, resulting in missed opportunities for early detection and prevention of colorectal cancer. Patient navigation and structured follow-up may improve colonoscopy completion, but implementation of these strategies is not widespread. METHODS: We conducted a quality improvement study using a Plan-Do-Study-Act (PDSA) Model to increase colonoscopy completion after abnormal FIT in a large federally qualified health center serving a diverse and low-income population. Intervention components included patient navigation, and a checklist to promote completion of key steps required for abnormal FIT follow-up. Primary outcome was proportion of patients achieving colonoscopy completion within 6 months of abnormal FIT, assessed at baseline for 156 patients pre-intervention, and compared to 208 patients during the intervention period from April 2017 to December 2019. Drop offs at each step in the follow-up process were assessed. RESULTS: Colonoscopy completion improved from 21% among 156 patients with abnormal FIT pre-intervention, to 38% among 208 patients with abnormal FIT during the intervention (P < .001; absolute increase: 17%, 95% CI: 6.9%-25.2%). Among the 130 non-completers during the intervention period, lack of completion was attributable to absence of colonoscopy referral for 7.7%; inability to schedule a pre-colonoscopy specialist visit for 71.5%; failure to complete a pre-colonoscopy visit for 2.3%; the absence of colonoscopy scheduling for 9.2%; failure to show for a scheduled colonoscopy for 9.2%. CONCLUSIONS: Patient navigation and structured follow-up appear to improve colonoscopy completion after abnormal FIT. Additional strategies are needed to achieve optimal rates of completion.

Strategies addressing barriers to clinical trial enrollment of underrepresented populations: a systematic review.

BACKGROUND: Underrepresentation of racial and ethnic minorities in clinical trials remains a reality while they have disproportionately higher rates of health disparities. OBJECTIVE: The purpose of this study was to identify successful community-engaged interventions that included health care providers as a key strategy in addressing barriers to clinical trial enrollment of underrepresented patients. DESIGN: A systematic review of the literature on interventions addressing enrollment barriers to clinical trials for racial and ethnic minorities was performed in Ovid MEDLINE, EBSCO Megafile, and EBSCO CINAHL. The systematic review identified 360 studies, and 20 were selected using the inclusion criteria. An iterative process extracted information from the eligible studies. RESULTS: The 20 selected studies were analyzed and then grouped by first author, nature of the clinical research initiative, priority populations, key strategies, and study outcomes. Nine of the studies addressed cancer clinical trials and 11 related to chronic medical conditions, including diabetes, hypertension management, and chronic kidney disease. The key strategies employed were categorized according to their presumed impact on barriers incurred at distinct steps in study recruitment: clinical trial awareness, opportunity to participate, and acceptance of enrollment. The strategies were further categorized by whether they would address barriers associated with minority perceptions of the research process and barriers related to how studies were designed and implemented. CONCLUSION: Multiple and flexible strategies targeting providers and participants at provider sites and within communities might be needed to enroll underrepresented populations into clinical trials.
