I worked emergency for three years before founding Vetch. The PMS we used at the time had a defensible architecture and a perfectly miserable user experience. Most ER software still does. This is a field guide to what good feels like, written for the doctors and techs who haven't had it yet.
The whiteboard
A real whiteboard at 3am has three properties: it shows the whole floor at once, it changes the moment a vital changes, and you can read it from the doorway. ER software should match all three. If you have to scroll, it's wrong. If a tech's update doesn't reflect for 20 seconds, it's wrong.
The note that signs at the door
In ER, the moment between the doctor finishing rounds and the doctor leaving the room is the only time the note will be most-true. Capture it then. Sign it then. Don't make the doctor catch up at the end of shift, because at the end of shift the doctor is wrong about half of what they saw at 4am.
The handoff card
Wash your hands. Read the card. Walk into the bay. That's the loop. The card has to support that timing — 20 seconds, comfortable on a phone, formatted for the eye-flicker pattern of someone who's been on shift for nine hours.
The board re-ranks itself
Severity changes? Patient moves. CRI started? Patient moves to in-care. Doctor finishes surgery? Their bay surfaces. Manual drag-and-drop is a tax you don't have time to pay.
What this is not
It's not a dashboard. It's not an analytics tool. It's a real-time operating surface for a building where patients can decompensate in 90 seconds. It should look more like a flight deck than a CRM.
If your ER software doesn't feel like that, change it. The patients can tell.
