Case Study: Aspirus Wausau Hospital achieves near-100% CPOE adoption and fast, secure Epic access with Imprivata OneSign

Simplify access to Epic EMR, enable CPOE

Aspirus Wausau Hospital, a 321‑bed community hospital in north central Wisconsin, struggled to get clinicians to use its Epic EMR and meet Meaningful Use goals because the login process was cumbersome—providers entered passwords as many as 120 times per shift—and an earlier single sign‑on product didn’t integrate tightly with Epic, impeding CPOE adoption. IT needed a fast, secure way to simplify access without adding complexity to clinical workflows.

The hospital deployed Imprivata OneSign (piloted and rolled out to ~100 servers, 500 workstations and 2,000 users), enabling badge tap No‑Click Access and re‑authentication only once every four hours. The solution drove nearly 100% CPOE adoption, cut repetitive password entry, improved clinician efficiency, and maintained HIPAA/IT security compliance while enabling further initiatives like desktop virtualization, EPCS and secure clinical messaging.
