Phone Booking · Every Legacy EMR
No reservation concept exists. The receptionist reads from a paper
book or a calendar tile. Two phone calls arrive at once.
Both get told the slot is free — because neither has
committed yet. One of those patients gets a callback at 2 PM
asking them to pick a different time.
Jane App · Online Booking
Jane reads the calendar at booking time. If two patients book the
same slot within the same request window, both can succeed
— the second write overwrites the first. There is no hold table,
no GUID lock, no conflict check on pending sessions.
Jane's own support documentation acknowledges this risk.
No reservation layer — race conditions possible
Accuro EMR · Physician Office
Accuro's online booking (where it exists) is a portal that
writes directly to the schedule. No hold, no countdown, no
conflict window. The system assumes bookings happen
sequentially — a 2005-era assumption that breaks the moment
your booking link goes into a waiting room TV or a social post.
Sequential-only architecture — fails under load
