STEMI Timeline Optimization
An alert-driven redesign of the door-to-balloon workflow that reduces PCI delays for heart-attack patients.
Overview
In a heart attack, minutes are muscle. The door-to-balloon window — from arrival to reopening a blocked artery — is one of cardiology's most important clocks, and it was running slow.
Working with a synthetic MGUH STEMI cohort in OpenEMR, I mapped the existing workflow, found where delays accumulated, and introduced alert-driven interventions that prompt the right action at the right moment.
The redesign reduced modeled PCI delays and improved projected 3-month mortality — a demonstration of how workflow and informatics, not just new drugs, move clinical outcomes.
At a glance
Door-to-balloon delays in STEMI care directly worsen patient outcomes, yet the workflow was reactive and manual.
A redesigned door-to-balloon workflow in OpenEMR using alert-driven interventions on a synthetic MGUH STEMI cohort.
Reduced PCI delays and improved modeled 3-month mortality outcomes for the cohort.
Highlights
- Mapped and diagnosed the door-to-balloon workflow
- Alert-driven interventions built into OpenEMR
- Tested on a synthetic MGUH STEMI cohort
- Reduced PCI delays and improved 3-month mortality
