Community Hospital Executes Zero-Downtime EHR Modernization Planning

About the Client

The client was a 450-bed community hospital delivering acute and specialty care across a diverse patient population. The hospital had been operating on Epic for several years but made a strategic decision to migrate to Cerner to align with regional interoperability initiatives and long-term vendor strategy. Given the hospital’s size and complexity, the transition carried significant operational and clinical risk.

To ensure a safe, structured migration without disrupting patient care, the hospital engaged Zymr to lead end-to-end EHR modernization planning, from clinical workflow consolidation to cutover sequencing.

Key Outcomes

85 Critical Clinical Workflows Standardized and Prioritized
18-Month Migration Roadmap Defined

Business Challenges

The hospital faced a highly complex migration scenario involving 28 clinical departments, each with unique workflows, documentation needs, and dependencies. Existing processes had evolved organically over time, resulting in duplication, inconsistency, and undocumented workarounds. Leadership needed a consolidated, prioritized view of critical workflows while ensuring clinicians remained productive throughout the transition. Any migration plan also had to minimize operational risk, avoid unplanned downtime, and support a tightly governed cutover timeline across clinical, IT, and administrative teams.

Business Impacts / Key Results Achieved

Zymr helped the hospital reduce EHR migration risk by replacing ad hoc planning with a structured, clinician-informed modernization roadmap. The engagement ensured operational continuity, protected patient safety, and positioned the organization for a smooth Epic-to-Cerner transition without unplanned disruptions.
