Epic vs Cerner vs athenahealth: Documentation Burden 2026

Start with NoPajamaTime's free 24-hour proof to create and review one note.

NoPajamaTime creates a draft outside the EHR. The clinician reviews it, copies only permitted narrative text into an appropriate EHR field, completes structured work separately, and signs inside the EHR. Universal native EHR write-back is not claimed.

Which EHR creates the most after-hours charting? We compared clicks per encounter, note completion times, after-hours hours, and physician satisfaction.

TL;DR

  • → Epic creates the most documentation burden (highest clicks, highest inbox volume) but scores highest in physician satisfaction among large health systems
  • → athenahealth has the lowest documentation burden and lowest implementation cost — best for independent practices
  • → Cerner sits in the middle and is losing ground to both; Oracle's acquisition has stalled innovation
  • → None of them solve after-hours charting — that requires AI ambient scribing layered on top

    The Inconvenient Truth About All Three

    The EHR you're on barely matters. Physicians on Epic, Cerner, and athenahealth all report spending 1–2+ hours charting after hours. The best EHR in the world still requires a physician to type, click, and review after patients leave.

    The debate between Epic and Cerner is a debate about which tool creates slightly less pajama time — not whether pajama time exists. According to AMA's 2025 survey, 62% of burned-out physicians cite their EHR as the primary driver , and that number is consistent across all three platforms.

    What can reduce after-hours charting isn't simply switching EHRs — it's changing the documentation workflow on top of whatever EHR you're on. Some AI scribes offer native integrations; others, including NoPajamaTime, use a clinician-reviewed copy/paste handoff into the existing EHR.

    The EHR is the foundation. The documentation burden is the layer on top. Fix the layer.
