Outcomes Associated with Use of the Cancer Risk Intake System among Primary Care Safety-Net Patients Identified As Needing Colorectal Cancer Screening

Despite demonstrated primary and secondary prevention benefits, screening for colorectal cancer (CRC) is sub-optimal. We implemented the Cancer Risk Intake System (CRIS) among a convenience sample of patients presenting for primary care in Dallas County safety-net clinics. CRIS, which assesses individuals' CRC risks and generates guideline-based screening recommendations for them and their providers, had been found in a randomized trial to facilitate risk-based screening, compared to usual care. Here, of 924 patients ages ≥50 who used CRIS, 699 were identified as needing screening, with 39.2% needing colonoscopy rather than FIT. However, following use of CRIS and patients' and providers' receipt of guideline-concordant recommendations, 20.9% elevated-risk patients received no screening orders, only 44.1% received guideline-concordant colonoscopy orders, and less than half of these (48.4%) completed colonoscopy. Guideline-concordant screening orders were more common for average-risk patients (62.5% received orders for FIT and 26.6% for colonoscopy). However, like their elevated-risk counterparts who received screening orders, more than half of average-risk patients in each order group (52.3% for FIT and 52.8% for colonoscopy) did not complete screening. We found no correlates for receiving screening orders, but higher comorbidity scores were associated with less screening completion among the average-risk group. We had hoped CRIS would facilitate risk-based screening but, although orders for and receipt of colonoscopy were more common for elevated- than average-risk patients, they were still suboptimal in this clinical setting with a "FIT-first" strategy. A stronger intervention may be necessary to increase guideline-concordant recommendations and screening among patients 50 and older.
