Introduction
As rural workforce shortages limit access to colonoscopies, Sanford Health is using a "human-in-the-loop" AI approach to better match colorectal cancer (CRC) screening modalities to patient risk. Since 2023, its enterprise-wide population health program has increased access to preventative care through an Electronic Medical Record (EMR)-embedded AI model that identifies average-risk patients who should receive stool-based testing (SBT) kits based on 85+ nontraditional risk factors, reserving colonoscopies for higher-risk patients.
Keep reading to learn how Sanford is expanding screening access and reducing colonoscopy wait times for rural patients across the upper Midwest.
Case Study Snapshot
Footprint: Headquartered in Sioux Falls, SD; 58 hospitals and 250+ outpatient facilities across the upper Midwest
Timeframe: 2023-Present
Challenge: Below-target colorectal cancer (CRC) screening rates due to barriers including limited gastroenterologist (GI) capacity to perform colonoscopies and primary care (PC) teams’ lack of familiarity with stool-based tests (SBTs). 2023 data showed that monthly colonoscopy rates (3,000 per month) would need to be more than doubled to reach programmatic goals of 8,000 per month.
Solution: Centralized, enterprise-wide CRC outreach and screening infrastructure that triages screening modality (colonoscopy vs. SBT) and associated outreach by patient risk. An AI-powered tool embedded in the electronic medical record (EMR) stratifies patient risk according to 85 nontraditional risk factors (e.g., employment status, psychiatric conditions).

Challenges Addressed
Keeping Care Close to Home
Reduces typical rural barriers to CRC screening via colonoscopy (e.g., travel time, inability to take time off work) for average-risk patients while maintaining their access to preventive care via SBT kits.
Addressing Social Drivers of Health (SDOH) in Rural-Specific Contexts
Incorporates tools and practices developed by Sanford and external screening kit partners that mitigate SDOH barriers to CRC screening, including transportation and economic status (e.g., financial assistance policies specifically for colonoscopy).
Key Outcomes (as of 2025)
Idea to Action: Operationalizing an Enterprise-Wide CRC Screening Infrastructure


Key Facilitators of Success Underlie Increase in CRC Screening Rates
Lessons Learned for Health Systems
1. For rural systems operating in workforce shortage areas, human-in-the-loop AI risk stratification approaches can help redirect existing capacity and increase access to services for those who need it most.
Rather than replacing or adding additional clinicians, Sanford deployed a human-in-the loop AI model that augments provider expertise with over 85 non-traditional risk factors while embedding clinical oversight at every critical decision point.
Triaging screening modalities by patient risk allowed Sanford to cull many average risk patients from the long colonoscopy waiting list during the initial launch, reducing wait times by over 2 months and increasing access for high-risk patients.
2. Rural enterprise population health initiatives should strive to protect the trusted relationships between PCPs and their patients in designing project workflows.
Relying on PCPs’ on-the-ground knowledge to integrate project processes into existing clinical workflows ensured that the project would not unintentionally burden patients. For example, a decision to include nursing home patients in the patient population was reversed once PCPs shared that they visited monthly and could have a conversation about screening at the point of care.
The project leverages PCPs’ trusted relationships to follow up and close the loop with average-risk patients after 3 instances of unanswered outreach.
What's Next?
Launch a collaborative, resource-based partnership model between Sanford, Tribal Nations, and a screening kit partner to address persistent CRC disparities among Tribal and Alaska Native populations
Apply project logic to ensure screening for patients whose SBT kits are ordered in the clinic setting
Plan to partner with newly acquired markets to ensure that screening infrastructure is scaled to Sanford’s full footprint in the future
