TL;DR: A reference architecture can standardize secure SSO, Epic integration, and enterprise access management in healthcare while simplifying clinical workflows, according to Imprivata. The governance lesson is that access design in clinical environments must balance speed, compliance, and identity control without treating usability as separate from security.
NHIMG editorial — based on content published by Imprivata: reference architecture for secure access, SSO, and Epic integration in healthcare
Questions worth separating out
Q: How should healthcare teams use reference architecture to improve access security?
A: They should treat it as a governance blueprint, not just documentation.
Q: Why does Epic integration create identity governance challenges?
A: Epic integration matters because it connects access security directly to high-pressure clinical workflows.
Q: When does single sign-on become a risk in healthcare environments?
A: SSO becomes risky when session handling, privilege scope, or step-up controls are not designed for shared devices and fast-moving clinical contexts.
Practitioner guidance
- Standardise clinical access patterns Use a reference architecture to define one approved approach for authentication, application access, and session behaviour across comparable clinical systems.
- Test SSO in live care workflows Validate single sign-on behaviour on shared workstations, during handoffs, and across Epic-linked workflows so usability problems do not become informal workarounds.
- Tie architecture to lifecycle governance Review how joiner-mover-leaver processes, access recertification, and exception handling map to the documented access model for each clinical role.

Reference architecture is only valuable when it turns identity policy into repeatable healthcare workflow design. In clinical environments, security fails when access logic is improvised site by site and system by system. A documented blueprint reduces variation, but only if the organisation uses it to standardise authentication, session handling, and integration patterns across the EHR estate. The practical conclusion is that governance teams should treat architecture as an enforcement mechanism for identity design consistency.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to Ultimate Guide to NHIs.
- 71% of NHIs are not rotated within recommended time frames, increasing the risk of compromise over time.
A question worth separating out:
Q: What should IAM teams review when building a healthcare reference architecture?
A: They should review authentication, integration points, workflow exceptions, lifecycle governance, and audit evidence together. A good architecture does not just connect systems. It defines how access stays consistent when staff move roles, when devices are shared, and when clinical urgency changes the normal workflow.
