When one of the nation’s largest integrated health systems, with a footprint stretching from the Great Lakes to the Southeast, set out to raise the bar on cognitive testing, they found their answer in Creyos. The platform’s highly sensitive and specific dementia screener, grounded in extensive scientific validation, gave clinicians a tool they could trust.
But finding the right assessment was only half the equation. In a health system with more than 1,000 care sites across multiple states, even the best clinical tool can fail to take hold if it doesn’t fit naturally into how care is delivered. The question was never just what to use — it was how to make it work.
The answer lay in integration. Creyos had the clinical substance. What it needed was a direct line into the environments where clinicians were already operating — and for this particular health system, that meant Epic.
By partnering with Redox, Creyos was able to close that gap, embedding cognitive assessments seamlessly into the health system’s existing Epic workflows. Ordering tests, capturing results, surfacing insights — all of it now happens within the system clinicians already know, without the manual workarounds that had quietly undermined earlier efforts.
This is the story of how that integration took shape, and why getting it right made all the difference.
The challenge: Bridging the workflow gap
To make cognitive testing a routine part of care, Creyos needed to do more than just exchange data. They needed to mirror the natural movements of a clinician and a patient— including patients who needed to complete assessments entirely from home, without a clinic visit. This required:
- Automated Bulk Ordering: Moving away from one-off tasks to identifying patient cohorts for assessment within Epic.
- Frictionless Patient Access: Utilizing SMART on FHIR SSO so patients could launch and complete assessments entirely from home, directly from a MyChart message, without new logins or a clinic visit required.
- Closing the Loop: Automatically filing results back into the patient record as discrete, actionable data — regardless of where the assessment was taken.
The health system’s infrastructure also presented a significant hurdle: two separate Epic instances, each with its own unique logic and highly bespoke configurations.
For most vendors, this would mean two entirely separate scoping, building, and maintenance projects. Without an interoperability partner, Creyos would have been forced to navigate the complexity of these simultaneous Epic builds on their own.
The solution: One connection for a unified experience
Instead of managing the variability of different Epic configurations, Creyos leveraged Redox as their integration layer. Redox acted as the translation engine, making these two disparate instances feel like one seamless experience for the Creyos team.
Leveraging the Redox Network to get started fast: Creyos was able to move faster by re-using secure VPN tunnels that Redox already had in place for the health system. Instead of waiting weeks for new infrastructure, they plugged into the existing Redox Network.
Automating the patient journey with Redox integration and data orchestration
- Workflow Orchestration: Redox handled the heavy lifting of receiving HL7 ORU messages, stripping unneeded data, and formatting it specifically for the Creyos database.
- SMART on FHIR SSO: Redox managed the handshake between Epic and Creyos, allowing patients to launch assessments directly from a MyChart message without new logins.
- Closing the Loop: Once complete, Redox formatted results back into a standard HL7 message, filing the outcome directly into the correct patient record in Epic.
