The most useful line in a medication list is the drug that is missing

At every medication review, ask what the patient has stopped and why, and reconcile the discharge list against the one before admission.

A repeat prescription list tells you what a patient is issued. It does not tell you what they take, and it is silent on the one thing that usually explains the consultation: the drug that used to be there.

So when a list looks unexpectedly short, or a patient's control has drifted without a clear reason, ask directly what they have stopped and when. Patients rarely volunteer it, partly because stopping felt like their decision rather than a clinical event, and partly because they expect to be told off. Asking without a note of accusation — what did you stop, and what happened that made you stop it — usually produces a side effect nobody recorded, a cost they did not want to mention, or a sentence from another clinician that was heard differently from how it was meant.

The same applies to drugs stopped in hospital. A medication paused for a procedure and never restarted is one of the commonest avoidable causes of deterioration after discharge, and it is invisible unless somebody compares the discharge list against the one before admission.

  • Ask what has been stopped and when, not just what is being taken
  • Ask what happened that prompted stopping — the answer is usually clinical
  • Compare the discharge medication list against the pre-admission list at the first review
  • Record the reason a drug was stopped, so the next clinician does not simply restart it

Why it matters

A drug that silently disappeared explains more consultations than any drug that is still on the list.
