Why it matters: Epic sets the date. Everything else has to bend around it. This health system handed migration, patient identity and legacy access to one partner, protected the date, and kept clinicians in patient care instead of in cleanup.

The challenge

The health system was converting to Epic on a hard, Epic-set go-live date. Success depended on migrating and validating large volumes of historical data, cleaning and reconciling the master patient index, and keeping legacy applications accessible throughout.

All of it had to happen while the organization kept caring for patients. There was no room to slip the date.

The partnership

The organization engaged e4health across its Health IT and HIM divisions. e4health led project management on the Epic side, guiding the build to an on-time go-live.

e4health also owned data migration, master patient index integrity and legacy application support, so internal teams could focus on adoption and patient care.

Live in EpicClean, validated MPI

Systems were built and data was in ahead of every Epic milestone, not after it.

The verdict: the vendor called it one of the smoothest go-lives they had seen in years, a testament to e4health's project management on the Epic side.

The approach

One partner leading the Epic build, from project management through migration, legacy support and go-live.

Epic project management

Program delivery
  • e4health project managers embedded on the Epic side, guiding the build to go-live.
  • Milestones, dependencies and risks managed to protect an immovable date.
  • Coordination across Epic, the health system and e4health teams.

Data migration & MPI

Data migration
  • 40 million records acquired from legacy systems and migrated to Epic.
  • Converted, mapped, loaded to build specs and validated against source.
  • Master patient index cleaned, reconciled and validated for Epic.

Legacy application support

Managed services
  • Roughly 40 legacy applications supported by a dedicated 31-analyst team.
  • 24/7 coverage across the 14-month engagement, with no off-hours fees.
  • Historical records kept accessible for clinical and revenue-cycle teams.

Clean go-live

Cutover
  • Command-center support through cutover and stabilization.
  • Systems built and data in ahead of every Epic milestone.
  • One of the smoothest go-lives the vendor had seen in years.

A 31-analyst team sustained coverage across roughly 40 applications. Closures outpaced openings at about 207 closed to 201 opened each week, so backlog fell instead of growing.

Why it worked

  • One owner, not three. The same team held migration, patient identity and legacy access, so nothing fell between vendors.
  • PM on the Epic side. Milestones, dependencies and risks stayed under control against a date that could not move.
  • Support built in, not billed by the hour. 24/7 coverage with no off-hours fees and no surprise invoices.
  • History stayed reachable. Clinical and revenue-cycle teams kept access to legacy records throughout the transition.

The result

An on-time, on-budget Epic go-live the vendor called one of the smoothest in years, delivered with e4health leading project management, 40 million records migrated accurately, and roughly 40 legacy applications supported around the clock, all through one accountable partner.
