How "Missed" is calculated
A scheduled dose moves to Missed (red) when the administration buffer expires. The buffer is set in eMAR Settings:
Buffer before (default 30 min) — how long before the scheduled time the dose can be recorded as on-time.
Buffer after (default 120 min) — how long after the scheduled time the dose still shows as Due now (amber). When this expires the cell flips to Missed (red).
Missed-notification delay (default 30 min after the after-buffer ends) — when the alert fires to nominated people.
Worked example. A medication scheduled for 08:00 with a 120-minute after-buffer becomes Missed at 10:00. The missed-notification alert fires at 10:30.
If you genuinely missed the dose
Click the (red) cell. The recorder opens.
Outcome → Missed (code 5).
Type the reason — fell asleep, was off site, forgotten, etc.
Submit.
If you gave the dose but forgot to record it
Use the Retrospective recording flow — see Recording retrospectively. The recording is timestamped with both the actual administration time and the moment of entry, and the timeline shows a violet "Late" badge so the discrepancy is visible to auditors.
Heads up — Don't back-date a recording by typing the original time into the "given at" field. The Retrospective flow exists precisely to keep records honest — using a normal recording for a late entry hides the actual delay.
