Health Equity in Colorectal Cancer Screening: Addressing Disparities in an Urban Clinic
You are the director of a federally qualified health center (FQHC) in an urban area serving a predominantly low-income, minority population. The clinic has 5,000 age-eligible patients (50-75 years) for colorectal cancer (CRC) screening. Current screening rate is 35%, well below the national target of 80%. Data show that screening rates are lowest among Black patients (28%) and uninsured patients (22%). The clinic offers fecal immunochemical testing (FIT) and colonoscopy referrals. FIT kit return rate is 45%. Colonoscopy completion rate after positive FIT is 60%. Barriers identified: lack of transportation, fear of colonoscopy, language barriers (30% Spanish-speaking), and mistrust of the healthcare system. The clinic has one part-time gastroenterologist and a patient navigator program that is underfunded.
1. Analyze the root causes of the low CRC screening rates and disparities in this clinic. What are the key contributing factors at the patient, provider, and system levels?
Read the worked answer
Root causes: Patient-level: lack of awareness, fear of colonoscopy, language barriers (Spanish), mistrust, transportation issues, cost concerns (uninsured), low health literacy. Provider-level: inconsistent recommendations, lack of time, cultural competency gaps, not using interpreters effectively. System-level: underfunded patient navigation, limited gastroenterology access (one part-time GI), poor tracking of FIT returns, no reminder systems, lack of transportation support, no systematic outreach, colonoscopy referral barriers (e.g., cost, scheduling). Disparities: Black and uninsured patients have lower rates due to structural racism, access barriers, and mistrust. FIT return rate is low (45%) and colonoscopy completion after positive FIT is low (60%), indicating follow-up failures. The clinic lacks a robust screening program with evidence-based interventions like mailed FIT outreach, patient navigation, and provider reminders.
2. Propose a multifaceted intervention plan to improve CRC screening rates and reduce disparities. Include specific strategies, metrics, and a timeline for implementation.

Intervention plan: 1) Mailed FIT outreach to all eligible patients, with prepaid return envelopes and culturally tailored instructions in English and Spanish. 2) Expand patient navigation: hire bilingual navigators to assist with scheduling, transportation, and education; use navigators to follow up on FIT returns and colonoscopy completion. 3) Provider education and reminders: implement electronic health record (EHR) prompts for screening, train providers on cultural humility and shared decision-making. 4) Language services: ensure interpreters and translated materials. 5) Transportation support: partner with ride-share services or provide bus passes. 6) Community engagement: partner with community health workers and faith-based organizations to build trust. 7) Improve colonoscopy access: increase GI time or partner with local GI practices; offer open-access colonoscopy. 8) Quality metrics: track screening rates by race/ethnicity, insurance, and language; monitor FIT return rates, colonoscopy completion, and time to colonoscopy after positive FIT. 9) Timeline: Phase 1 (months 1-3): secure funding, hire navigators, develop materials. Phase 2 (months 4-6): launch mailed FIT and provider reminders. Phase 3 (months 7-12): expand navigation, monitor metrics, and adjust. 10) Evaluation: quarterly review of screening rates; aim to increase overall rate to 60% in 1 year and reduce disparity gap by 50%. 11) Sustainability: bill for navigation services, seek grants. 12) Address mistrust: use trusted messengers, transparent communication.
