The short answer
- Call early. A clear call about a patient who turns out to be fine costs your registrar two minutes.
- If criteria are met and no one can come, call outreach, or 2222 yourself.
- Use SBAR and lead with what you need.
- If you’re not happy, say so more clearly, and go up the chain.
You will never be criticised for a clear, early call about a patient you’re worried about. Registrars worry about the juniors who don’t call, not the ones who do.
Call now if
You never need to wait for a patient to meet the criteria. If you or the nurse are worried, call.
How to make the call
Before you dial, have the observations and their trend, the chart, the latest results and your own plan in front of you. Then use SBAR:
Give the Situation (who you are, the patient and why you’re calling), the relevant Background, your Assessment, and your Recommendation: what you need, and by when.
Lead with what you need:
“It’s Alex, the FY1 on call. I’d like you to review Mrs Tran on Ward 6 now. I think she’s septic: her blood pressure has dropped and she’s newly confused.”
End by saying back the plan: what you’ll do, what they’ll do, and when you’ll call again. Write it in the notes with the time and the registrar’s name.
If you’re not happy with the answer
- Say it again, more clearly, starting with the finding that worries you most.
- Make your concern harder to miss using CUS: “I’m Concerned… I’m Uncomfortable… I think this is a Safety issue.”
- If you’re still not happy, call the consultant, or call the critical care outreach team if the patient meets the criteria.
- Write down who you called, when, and what they advised.
General education for doctors, not advice about a particular patient. Your hospital’s policies and your seniors always come first.
