Help us understand what makes an ED schedule better.
Compare realistic emergency medicine physician schedules and tell us which you'd rather work. Your responses help evaluate whether objective scheduling measures correspond with physician preferences.
You'll choose an 8- or 12-hour schedule bucket, then compare pairs head-to-head — no login required.

Why CAIER Insights exists
CAIER converts fatigue and circadian science into objectives that scheduling engines can optimize — so schedules are built for the humans who work them, not just for coverage.
"Most scheduling systems are designed to fill shifts.
Physicians experience schedules.
Why compare two schedules?
Head-to-head schedule comparisons are the simplest and most scientifically rigorous way to determine whether objective scheduling indices actually predict physician preference.
