Abstract
Adherence to colorectal cancer screening is suboptimal, particularly in medically underserved populations. We report here on our assessment of the impact of offering a blood-based screening test on screening rates in a health fair setting. Patients attending student-run health fairs who met colon cancer screening guideline eligibility criteria received a recommendation to attend that screening station. Patients were offered recommended accepted screening methods, and if they declined they were offered blood-based testing. Screening rates, test outcomes, and the rate of follow up completion of colonoscopy were measured and compared with historic screening outcomes. Of 1401 screening eligible patients, 640 (45.7%) attended the colon cancer screening station, of whom 460 were eligible for assessment. Amongst these, none selected colonoscopy, 30 (6.5%) selected FIT, and 430 (93.5%) selected blood-based testing. Only 2 patients returned the FIT. For the blood test, 88 were positive, and 20 of these received a follow up colonoscopy. Based on this assessment, blood-based testing is an effective method to increase screening rates in medically underserved populations, though efforts to further improve access to follow up colonoscopy are necessary.
