Great River Eliminates PA Backlogs with Lamar Health

Great River's clinical team was drowning in PA’s - 60 minutes per submission, backlogs stretching weeks. With Lamar Health, they cut that process to 3 minutes and cleared the backlog entirely

  • 60+ minutes to 3 minTotal time per PA
  • Weeks to 0-3 DaysTurnaround to payer submission
  • 90% decreaseReduction in staff time per PA

The Challenge

Before Lamar Health, Great River's PA workflow was fragmented and entirely manual. Staff spent 15-30 minutes hunting down the right records in Cerner for a single patient, then another 15-30 minutes manually processing the submission. With each PA consuming up to an hour of dedicated human labor, backlogs were inevitable - submissions sat in queues for weeks before reaching the payer, delaying critical medication decisions and burning out staff.

The Solution

Great River went live on the Lamar Health platform on March 2, 2026. . Following a brief two-week stabilization period, Lamar Health took over document retrieval, demographic extraction, and clinical data compilation automatically within Cerner- shifting staff from data-entry work to high-level clinical review.

The Results

60+ min to 3 min per PA
