When something goes wrong with a patient or a med

The dose you gave two hours late

The dose went in at 1100 and the MAR wants 0900. Thirty honest seconds of charting, and the next nurse times the next dose right.

The 0900 meds went in at 1100. You spent the morning with a patient who was going downhill, and nobody could cover your other rooms. Now the eMAR is waiting for a click, and it would be easy to let it show 0900. Don't. Charting the real time with a reason takes about thirty seconds, and the next nurse gets an honest record.

Key points

  • Chart the time you actually gave the dose. Never the scheduled time.
  • Use the late or variance reason field and add one short line with the real cause. Example: one RN covering 7 patients after a call-out.
  • Check whether the drug is on your facility's time-critical list. If it is, follow the notification procedure and chart who you told, when, and what they said.
  • Chart any effect on the patient (a BG, a BP, a symptom), or chart that there was none. Use the actual number.
  • If the delay moves the next dose time, chart that. Otherwise the next shift may give two doses too close together.

Every entry on the right answers the same five questions: when it was given, when it was due, why it was late, who knew, and how the patient was.

A late dose charted at the scheduled time

The usual mistake is a MAR that looks on time. Either you chart the dose at the scheduled time, or the eMAR fills in the scheduled time and nobody fixes it. Sometimes the late reason box gets one word, busy, and that's it.

That causes real problems:

  1. The next nurse times the next dose off yours. You gave q8h vancomycin at 1200 and the chart says 1000, so the 1800 dose lands six hours after the real one. Troughs, sliding scales and PRN intervals all count from the time on the chart.
  2. Labs get misread. A drug level or glucose drawn after a dose that looks on time gets read against the wrong clock.
  3. The staffing problem stays hidden. If every late dose is charted on time, a unit that's short every Tuesday looks fine on paper. Pharmacy and management only see a pattern when the variance reasons are recorded.
  4. The record has to make sense later. Whoever reviews the chart won't remember your shift. A late dose with a clear reason is easy to follow. A gap with no explanation, or a time that doesn't match the Pyxis pull log, raises questions. You could have answered them at the time.

A late dose with a reason is just a normal entry. A late dose charted as on time is a second problem added to the first one.

Bottom line

Chart the real time and a one-line reason. The next nurse will time the next dose off what you wrote.

Official guidance

  • Dose went in early or late? Chart the time you actually gave it, so whoever gives the next one can keep the right interval. (Medscape, PrescQIPP)
  • Dose outside the allowed window: record the reason for the variance on the MAR. (Medscape, Providence policy)
  • Time-critical med delayed past the allowed window: the facility procedure should include notifying the prescriber, and you document that the notification happened. (ISMP, American Nurse)

What this rests on

No published decision turned up for this question. We looked, and the searches are in the record. So this article stands on published guidance and on how the question is asked on the floor, not on a court opinion. That is a weaker footing than the rest of the guide, and you should know it before you rely on it. The decisions behind the other articles are all in one place.
