Gaps are slots nobody filled; the waitlist is who could have. This report shows both so you can see how much of the empty time was avoidable.
What it shows
Waitlist & gaps is a snapshot of the current waitlist at the location, oldest entry first, with each patient's preferred practitioner and type, days waiting and status, Waiting or Notified.
Filters: a location. It needs the operational reports permission, which every role has.
Reading it
Headline figures: On waitlist, Notified, Waiting, Longest wait.
Columns: Since, Patient, Preferred practitioner, Preferred type, Days waiting, Status.
Acting on it
A long wait against a practitioner with gaps on the calendar is a booking to make today, see Manage the waitlist. Entries marked Notified were offered a freed slot and haven't booked; call them or dismiss them.
