Safety-netting: what to say, a template and worked examples

The short version

• Good safety-netting says what to look out for, when to act (or when to come back if not better) and where to go (GP, NHS 111, 999 or A&E).
• NICE's suspected cancer guideline (NG12) tells clinicians to explain "which symptoms to look out for and when they should return", and to remember that test results can be falsely negative.
• The RCGP's SCA toolkit asks for a "safe and SMART safety netting plan" and suggests checking understanding: "Get them to repeat to you when they would come back".
• One of the RCGP's SCA feedback statements, under clinical management, is "Inappropriate or inadequate arrangements for follow-up, continuity and/or safety netting".
• The GMC marks PLAB 2 in three domains, including clinical management skills. Its pages don't publish a station checklist, so safety-netting is best treated as part of every management plan.
• Vague advice ("come back if you're worried") is the most common weak point. Name the symptoms.

What safety-netting is

Two official or peer-reviewed sources describe it:

1. BJGP (Edwards et al. 2019), a study of recorded UK GP consultations: safety-netting advice is "information shared with a patient or their carer designed to help them identify the need to seek further medical help if their condition fails to improve, changes, or if they have concerns about their health".
2. NICE NG12, Suspected cancer: recognition and referral (published 2015, last updated April 2026). NICE describes safety netting as active monitoring in primary care through timely review and action after investigations, and active monitoring of symptoms in people at low (but not no) risk of having cancer. It recommends that clinicians explain which symptoms to look out for and when to return, and that they keep in mind that a test result can be a false negative.

The BJGP paper notes that Roger Neighbour first described a safety-netting checkpoint, in his book The Inner Consultation (1987), as one way of handling uncertainty.

The three parts of a safety net

Add a fourth part whenever there is a test or referral: what happens next and who chases it. "If you haven't heard about your results by Friday, please call the surgery."

A safety-netting template

Use it as a structure, not a script:

1. Expected course: "Most people with this feel better within…"
2. Red flags, in plain words: "If you notice … or …"
3. Action and urgency: "…please call 999 / go to A&E / call NHS 111 / book an appointment, the same day."
4. If not improving: "If it isn't better by … come back and we'll look again."
5. Tests and referrals: "You should hear by … If you don't, call us."
6. Teach-back: "Just so I know I've explained it well, can you tell me when you'd get help?"
7. Written backup if useful: a leaflet or a text message with the same points.

Teach-back is in NICE's shared decision making guideline (NG197) as a way to check understanding, and the RCGP's SCA toolkit suggests it for safety-netting.

Worked examples

All three are examples written by Confetto for practice (not real exam stations). Clinical content is kept general; follow current NICE/CKS guidance and local protocols in real practice.

Example 1: Low back pain (PLAB 2 or SCA, face to face)

A 42-year-old with three days of low back pain after lifting, no warning signs on history. After the plan:

"Most back pain like this gets better over a few weeks, and keeping gently active helps. There are a few rare but serious signs I want you to know about. If you get numbness around your back passage or genitals, new difficulty passing urine or controlling your bladder or bowels, or weakness in your legs, go to A&E straight away, day or night. If the pain isn't starting to improve in a couple of weeks, or it's stopping you working, book to see me again. Can you tell me back what those warning signs are?"

Example 2: A child with a fever, telephone consultation (SCA style)

A parent calls about their 3-year-old with a temperature since yesterday, who is drinking and playing between doses of paracetamol, with no warning signs on questioning.

"From what you've told me, this sounds like a viral infection, which usually settles in a few days. I want you to know when to get help quickly. Call 999 or go to A&E if she has a rash that doesn't fade when you press a glass on it, struggles to breathe, is very sleepy or hard to wake, or has a fit. Call NHS 111 or us the same day if she stops drinking, has far fewer wet nappies or wees, or you feel she's getting worse. If the fever is still there after a few days, we should see her. What would you do if you noticed one of those signs tonight?"

On the phone you can't see the child, so the safety net carries more weight. The RCGP says some SCA cases are audio only.

Example 3: Waiting for test results (any setting)

"I've sent off the blood tests. You should get the results in about a week. If you haven't heard by next Wednesday, please ring us. Don't assume no news is good news. And if your symptoms get worse before then, or you notice weight loss you can't explain, come back sooner. A normal test doesn't always rule everything out, so if things don't settle, we'll look again."

This one follows NICE NG12's two ideas: timely review after investigations, and remembering a result can be falsely negative.

How safety-netting is marked

In the SCA, the clinical management and medical complexity domain "is weighted in comparison to the other two domains", according to the RCGP's marking page.
