Fair schedules for the ER

Medestra builds your emergency physicians' schedule: every shift covered, your department's written rules kept, the hard shifts shared evenly.

One scheduling period with Medestra: doctors' requests, the checks, the solver building the month, then publishing.

Against an ER's own schedule

Spring, summer and fall 2026 · 39 weeks · 3,448 required shifts

A Montreal ER. Same doctors, same shifts, same time off: the schedule the department worked, against the one Medestra built.

Four steps per period

  1. Your physiciansFirst, each doctor enters time off and preferences in the app.
  2. Medestra checksThen every input is audited against your rules, and each doctor verifies their numbers before any target goes out.
  3. Our ER solverNext, a solver strategy built for emergency departments breaks the period down and builds it, measured against your rules at every step.
  4. You approveLast, you review, publish, and trades open.

The app every physician carries

Each doctor has Medestra on their phone, in English or French.

  • See every shift, today's first
  • Enter time off, availability and preferences
  • Message the scheduling team
  • Get notified when the schedule changes
  • Swap shifts directly, or list one on the marketplace

Coming next: Shift Wormholes

Sometimes no two-person swap works: you want Dr B's Saturday, but Dr B doesn't want your Tuesday night. A Wormhole finds a circle of three to five doctors where each one gives a shift to the next and receives one that fits better.

ABCD
You giveTue · Night
You receiveSat · Day
  1. The app finds the circle among shifts doctors have listed for trade.
  2. Every shift is rechecked and held: no overlaps, and the rest between shifts protected.
  3. Everyone accepts the same offer. One no, and nothing changes.
  4. The scheduler confirms, and every shift changes at once, or none does.

Everyone receives a better-fit shift. The exchange completes only if all participants accept.

Questions, answered

Three 2026 periods at a Montreal ER: spring, summer and fall. Both schedules use the same doctors, shifts and time off. The department's schedule is the one it actually worked. Both are counted by the same code against the department's written rules. On the hospital's own hardship score the results are mixed, and we say so.
