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.
Editorial analysis by NHI Mgmt Group, based on content published by Imprivata: “What is reference architecture, and how does it help access security healthcare customers?”.
Key questions
A: Treat Epic access as an identity architecture problem, not a login convenience issue.
Q: When does SSO improve healthcare access security, and when does it create new risk?
A: SSO improves security when it removes password reuse, centralises authentication, and reduces workarounds.
Q: What are the signs that clinical access workflows are outpacing identity controls?
A: Common signs include repeated login bypasses, shadow workflows, inconsistent access patterns across facilities, and pressure to weaken authentication during care delivery.
Practitioner guidance
- Define a clinical reference architecture Document the approved patterns for Epic access, SSO, and enterprise access management so local teams are not improvising their own integration model.
- Map login friction to workflow risk Review where repeated authentication or access delays are driving unsafe workarounds, then redesign those access paths before expanding them further.
- Validate Epic integration controls Test that the identity flow supports strong authentication, session governance, and traceable access decisions across the Epic workflow.
Bottom line: Healthcare access design works best when reference architecture, SSO, and EHR integration are treated as one governance problem.

Reference architecture is the governance layer that clinical IAM often lacks. Healthcare teams frequently treat access integration as a deployment task, but this article shows the stronger pattern: a reference architecture turns secure access into a repeatable operating model. That matters because Epic access is not isolated from workflow design, compliance obligations, or user behaviour. The practitioner takeaway is to manage access design as an architecture discipline, not as a series of local fixes.
A few things that frame the scale:
- 60% of healthcare organisations do not assess a vendor's security before signing a contract that grants access to protected health information, according to Ponemon Institute's 2023 Third-Party Risk in Healthcare report.
A question worth separating out:
Q: What should identity and IAM leaders standardise first in an Epic access programme?
A: Start with the reference architecture that defines the approved access pattern across authentication, integration, and workflow design. That gives teams a common baseline for implementation and review, instead of letting every site or application team invent its own version of secure access.
