Safety-netting fails less often because it was omitted than because it was vague. "Come back if you get worse" asks a patient to make a clinical judgement they have no basis for, and the ones who most need to return are frequently the ones most reluctant to look like they are making a fuss.
A usable safety net has three parts: a specific sign, a time, and a route. Not "if the pain gets worse" but "if the pain moves to the right lower abdomen, or you start vomiting, come back the same day, and come to this clinic, not the pharmacy." Not "if the fever continues" but "if you are still feverish on Thursday."
Write it down. In a short consultation in a second or third language, with a relative who will be the one deciding at 10 pm, the written line is what survives the walk home. It takes fifteen seconds and it is the only part of the consultation that operates after the patient has left.
- Name a specific sign, not a general worsening.
- Name a day or an hour, so the patient knows when the plan has failed.
- Name where to go, since the default is often a pharmacy rather than a clinic.
- Write the three parts on the prescription or slip the patient takes home.
- Check it with the relative who will be present that evening, not only with the patient.
Why it matters
It is the only part of the consultation still working after the patient has gone home, and vagueness is where it fails.
