MAR (Medication Administration Record)

A medication administration record is the ward-level chart showing, for each prescribed medicine, every scheduled dose and what happened at it. A dose is given, held, missed or refused, and each of those is an event with a time and a person attached. It sits downstream of the prescription: the order says what should happen, the MAR records what did.

Why it matters in a hospital

The gap between prescribed and administered is where inpatient medication safety lives. A drug charted but not given, or given twice because two nurses each thought the other had not, is the failure this record exists to prevent — and it can only prevent it if the chart is current, not written up at the end of a shift. It is also a legal record: in any later question about care, what was actually given and by whom is the fact that matters, which is why corrections should appear as amendments rather than overwrite what was first recorded.

How Trisvio handles it

Trisvio's MAR is append-only: a correction is a new event, and the grid shows when a cell has been amended rather than silently displaying the latest value. Recording an administration requires its own permission, held by nurses and doctors (and by hospital administrators by default) and deliberately not by reception, and a non-given entry over a recorded dose requires an explicit confirmation rather than quietly superseding it.
