Leo Martin, a fictional 29-year-old warehouse worker, is assessed with a likely self-limiting respiratory infection. His observations are reassuring, he can drink, and there is no current indication for hospital referral. The diagnosis is not certain at this early stage, so deterioration and diagnostic evolution must be safety-netted.
No real patient or identifiable patient information is used.- State the expected course while acknowledging that the clinical picture may change.
- Give observable red flags, a time threshold and the correct level of help for each.
- Check practical ability to follow the plan and document safety-netting clearly.
See the purpose behind each line
Your assessment today is reassuring and this is most likely a viral infection, but symptoms can change. I want us to agree exactly what you should do if they do.
Call 999 now if you become severely short of breath, collapse, become confused, or your lips or skin look blue or grey. Seek same-day urgent advice through your GP or NHS 111 if breathing becomes harder, you cannot keep fluids down, you pass much less urine, or you are getting rapidly worse.
If you are not beginning to improve over the next three days, arrange a review even if none of those red flags occur.
Do you have a phone, transport and someone who could help if you became more unwell?
Yes. My partner is at home tonight.
Please tell me what changes would make you call 999, and what you would do if you simply were not improving.
“The findings are reassuring today, but they are a snapshot and the illness may evolve.”
“If this specific change happens, seek this level of help within this timeframe.”
“If you are not improving by this named time, arrange reassessment even without a red flag.”
“Is there anything practical that could stop you following this plan?”
“Come back if you feel worse.”
‘Worse’ is subjective and gives no action, destination or timeframe.“It is only viral.”
It converts a likely working diagnosis into false certainty.“Go to A&E if worried.”
It gives no observable threshold and may over- or under-triage.“You know the usual red flags.”
It assumes knowledge and fails to make the safety plan testable.- Providing red flags without saying whether to call 999, seek same-day review or book routine follow-up.
- Giving a long generic list that the person cannot remember or apply.
- Omitting a time-based review point for failure to improve.
- Not checking access, support, language, health literacy or the person’s understanding.
Test the communication decision
Could I do this reliably?
Rewrite one safety-netting phrase you commonly use so that it names the trigger, timeframe and route to help.
