Safety-netting for deteriorating patients — the AU general practice guide

Safety-netting is the structured clinical communication a GP uses when a patient’s diagnosis remains uncertain or their illness could deteriorate — telling them what symptoms to watch for, when and how to escalate, and confirming they understand the plan before they leave. The consequence of not doing it, documented in coroner after coroner across every Australian state, is a patient who returns 24–72 hours later in septic shock, or a family who calls triple zero when the information they needed was available at Monday’s appointment. Almond, Mant and Thompson’s foundational BJGP 2009 paper established the evidence base; Greenhalgh et al. BJGP 2020 reframed it as “best practice in the face of uncertainty.” In Australian general practice, safety-netting is now a RACGP accreditation requirement and an ACSQHC clinical safety standard — and the absence of a documented safety-net is one of the most commonly cited contributing factors in preventable-death coronial findings.

A. Core clinical — the AU general-practice framework

What safety-netting is

Safety-netting addresses a structural reality of general practice: most consultations end with a working diagnosis that is probabilistic, not definitive. The clinician’s job is not only to treat the most likely diagnosis but also to prepare the patient and family for the scenario where the less likely — but more dangerous — diagnosis turns out to be correct. The Jones BJGP 2018 taxonomy describes three types: active (clinician-initiated callback or result-chase); passive (patient-initiated return on a red flag); and diagnostic (explicit acknowledgement of live differentials with a named worsening pathway). All three are needed in different proportions depending on risk.

The five-element script

A defensible safety-net requires five elements, every consultation with diagnostic uncertainty:

1. Name the working diagnosis and the alternatives still in play. “Most likely viral upper respiratory infection — but I cannot completely rule out early chest infection or sepsis at this stage.”
2. List specific red-flag symptoms in plain English. Not “if you feel worse” — instead: “fast breathing, temperature above 38.5 with shaking, difficulty staying awake, mottled or blue-coloured skin, no urine all day, a rash that does not go pale when you press it.”
3. Name the route and time-frame for each red flag. Call the practice during business hours, call healthdirect on 1800 022 222 after-hours, go to the emergency department, or call 000 — specify which applies to which symptom.
4. Teach-back. Ask the patient or carer to repeat the plan in their own words before leaving. Document that this was done.
5. Document the actual words used. “Advised to return or call 000 immediately if: [list]. Written information given. Understanding confirmed. Follow-up: nurse call at 24 h.”

Jones et al. BJGP 2019 video-recorded consultations confirmed that verbal-only recall is less than 50% at 24 hours. Written information plus verbal doubles retention and produces a contemporaneous court artefact.

Tracer presentations — mandatory safety-net, no exceptions

The ACSQHC Sepsis Clinical Care Standard 2022 and accumulated coronial findings identify presentations where a properly documented safety-net is non-negotiable:

Presentation	What is at stake	Minimum action
Infant under 3 months, temperature ≥38°C	Meningitis, occult bacteraemia, UTI	Same-day paediatric emergency department — not safety-net to home
Child 3–24 months, fever without focus ≥39°C or lasting >5 days	Meningococcaemia pre-rash, UTI, serious bacterial infection	24–48 h reassess plus same-day red-flag return plan
Suspected sepsis, any age	Time-critical; ACSQHC Sepsis CCS quality statements 1–7	Transfer, not safety-net
Non-blanching rash or first-or-worst headache	Subarachnoid haemorrhage, bacterial meningitis	Same-encounter emergency department
Chest pain, low-risk, discharged	MI, pulmonary embolism, aortic dissection	Document HEART score rationale; same-day return or triple zero if symptoms recur
Acute abdominal pain not admitted	Appendicitis, ectopic pregnancy, ischaemic bowel	12–24 h reassess plus explicit red-flag plan
New confusion in older adult	Sepsis, drug toxicity, intracranial haemorrhage, hyponatraemia	Family-witnessed plan; same-day if progressing
Immunocompromised patient with any fever	Neutropenic sepsis, opportunistic infection	Same-day full blood count or emergency department
Diabetes plus acute illness	Diabetic ketoacidosis, hyperosmolar hyperglycaemic state	Sick-day rules, fingerstick ketones, same-day return threshold explicit
Anticoagulated patient, fall or new pain	Delayed intracranial haemorrhage, retroperitoneal bleed	Low threshold for emergency department
Post-procedure or post-operative days 1–7	Bleed, anastomotic leak, wound infection, VTE	Surgical-team contact details plus emergency plan named

History — before formulating the safety-net

The safety-net script follows from what the clinician learns. Before writing it, the history should establish: what the patient feared (“What are you worried it might be?” — not asking this is a recurring coronial finding); trajectory (improving or worsening over the consultation period); red-flag screen (fever pattern, mental-state change, breathing effort, urine output, rash distribution); access modifiers (lives alone, no phone, distance to emergency department, language barrier). The access modifier screen shapes the route — a patient 90 minutes from the nearest emergency department needs a lower threshold for ambulance rather than drive-yourself instructions.

Documentation — the protective phrase library

The clinical note that protects the GP at inquiry contains five components, drawn from Avant Claims and Complaints Insights and the ACSQHC quality statement 6 on transitions of care:

Vitals (include respiratory rate and conscious state every time): “T 38.1, HR 102, RR 18, BP 114/74, SpO₂ 98% RA, GCS 15. NEWS2 = 2.”
Working diagnosis and differentials: “Working dx: viral URTI. Differentials in play: early bacterial lower respiratory tract infection, early sepsis — discussed with patient.”
Verbal red-flag advice: “Advised to return or call 000 if: fast breathing, rigors with temperature above 38.5, drowsiness or difficult to wake, non-blanching rash, no urine output all day.”
Written material: “HealthDirect handout given. 1800 022 222 noted.”
Understanding confirmed: “Patient repeated red flags back and stated route of escalation.”
Follow-up plan: “Practice nurse to phone at 24 h.”

Documenting the respiratory rate is the most commonly skipped and most frequently criticised vital sign at coronial inquiry. A documented set of normal vitals — including respiratory rate — is the strongest single piece of contemporaneous evidence that the patient was not septic at the time of consultation.

B. Evidence — why safety-netting reduces preventable deterioration

Sepsis Australia’s Australian Sepsis Network reports approximately 55,000 sepsis admissions and 8,700 deaths each year in Australia. The ACSQHC Sepsis Clinical Care Standard information for clinicians repeatedly found cases missed because clinicians did not listen to patient or carer concern — this is the explicit basis for quality statement 6 on transitions of care. Missed and delayed diagnosis is the leading clinical category in Avant general-practice indemnity claims across a five-year review of 567 closed claims.

The classic loss-of-life claim profile: febrile patient seen at a standard appointment, brief consultation, no documented red-flag advice, deterioration within 24–72 hours. The counterfactual safety-net costs two to three minutes. The Almond BJGP 2009 evidence synthesis and the Shared Safety-Net Action Plan (SSNAP) PMC 2022 demonstrate that structured safety-netting shortens time to cancer diagnosis and is associated with reduced missed-diagnosis harm across a range of acute presentations.

Proactive 24-hour callback — clinician-initiated — is the highest-value single change. It reaches patients who will not self-present, detects overnight deterioration, and is billable as a telehealth phone consultation for established patients. The Nuffield Oxford safety-netting programme demonstrates consistent cancer diagnostic delay reduction with active safety-net models.

C. Early-warning tools and their limits

The NICE NG143 traffic-light tool for febrile children and the qSOFA / NEWS2 scores for adults are useful structured prompts, not substitutes for clinical gestalt. Verbakel et al. BJGP 2022 found NICE NG143 has imperfect specificity in a low-prevalence general-practice setting. Churpek et al. AJRCCM 2017 showed NEWS2 outperforms qSOFA for early sepsis detection. The principle: use the tool as a documented prompt, record the score and the action threshold, then apply gestalt. A score calculated and ignored in the record is worse than no score — it documents a decision not taken.

Vitals trajectory matters more than a single reading. Re-checking 30–60 minutes after giving an antipyretic or completing initial management is the most under-used clinical manoeuvre in general practice. A second set of improving vitals is the strongest predictor that the current working diagnosis is correct. A second set that has not improved is the trigger for immediate escalation, not a third appointment.

Diagnostic momentum is the cognitive trap safety-netting defends against. Once “viral upper respiratory infection” appears in a record, every subsequent clinician — the locum, the after-hours doctor, the emergency triage nurse — anchors on it. A documented list of live differentials disrupts that anchor. Write it in the note, not only in the verbal consultation.

D. Australian operations

MBS billing — the safety-net consultation is usually Level C

A properly executed safety-net consultation for a tracer presentation — history, examination, red-flag communication, teach-back, written material, documented vitals — typically exceeds 20 minutes and meets MBS item 36 (Level C, 20–40 minutes). Under-billing at item 23 (Level B) reflects under-doing the consultation. Document start and end time and the components completed.

The proactive 24-hour phone callback is billed as MBS item 91891 (telehealth phone, Level B) where the 12-month face-to-face relationship rule is met, or item 91892 for a longer call. Video equivalents apply. First contacts for a new acute illness should generally be face-to-face; the proactive callback the following day is a telehealth-eligible follow-up.

RACGP and ACSQHC accreditation framework

The ACSQHC National Safety and Quality Primary and Community Healthcare Standards 2021 — Recognising and responding to acute deterioration criterion — requires documented processes for recognising deterioration, responding to patient and carer concern, and escalating appropriately. RACGP Standards 5e criterion GP2.1 — Continuous and comprehensive care — and criterion QI1.3 — Safety in pathology and imaging results (closed-loop recall) — are the two most commonly cited gaps at accreditation reviews and coronial inquiries.

Closed-loop recall is a non-negotiable practice system requirement. A result filed without action has contributed to preventable deaths documented in multiple Australian coronial findings. Every practice needs a documented workflow that names who is responsible for acting on abnormal results and what happens when a patient cannot be reached. Patients with deferred imaging need an explicit interim red-flag plan — “we will call you when the scan is booked” is not sufficient.

After-hours escalation pathways

Patients must leave with a specific phone number, not just “call your GP.” Provide at least one:

• healthdirect 1800 022 222 — national, 24/7, nurse triage plus symptom checker
• Qld: 13HEALTH 13 43 25 84
• Vic: Nurse-on-Call 1300 60 60 24
• Mental health: Lifeline 13 11 14, 13YARN 13 92 76, Beyond Blue 1300 22 4636
• Diabetes sick-day advice: Diabetes Australia

Notifiable disease reporting

Some presentations requiring safety-netting also trigger mandatory disease notification — meningococcal disease, pertussis, measles — which runs alongside and in addition to the safety-net. Both obligations must be fulfilled.

E. Special populations

Children. The infant under 3 months with any fever is never safety-netted home — same-day paediatric emergency department is the standard. For children aged 3–24 months, the NICE NG143 traffic-light tool is the structured prompt; amber or red features trigger same-day reassessment. Parents are the detection network overnight — a carer-facing safety-net is what protects the child.

Older adults with new confusion. Cognitive impairment prevents self-reporting of deterioration. The safety-net must involve a family member or carer who will observe overnight. New confusion in an older adult has a broad dangerous differential — sepsis, medication toxicity, intracranial haemorrhage, hyponatraemia, hypoglycaemia — and most are time-critical. Family need to know that new confusion is an emergency department presentation, not a next-morning GP phone call.

Pregnant women. Fever with rigors, reduced foetal movements, severe headache, or visual disturbance are emergency department presentations. The obstetric escalation pathway must be named explicitly — “go to the labour ward at [named hospital], not the emergency waiting room” if that is locally appropriate.

Immunocompromised patients — on immunosuppressants, chemotherapy, or with HIV — have blunted inflammatory responses. Fever may be the only sign of life-threatening sepsis, and the patient may not feel as sick as they are. The safety-net threshold is same-day emergency department or full blood count, not a next-day appointment.

Aboriginal and Torres Strait Islander patients. Culturally and linguistically adapted safety-netting — in-language written handouts, TIS National interpreter 131 450, family involvement in planning — is recommended by the ACSQHC PCHC Standards and the RACGP. Equity gaps in coronial cases concentrate in consultations where language and cultural barriers prevented the safety-net from being understood.

When to escalate

Transfer to emergency department or call 000 — do not safety-net to home and review — when:

• Any sepsis red-flag feature: qSOFA ≥2, rigors with fever, deteriorating conscious state, mottled skin, hypotension, oliguria
• Infant under 3 months with any fever
• Non-blanching rash anywhere on the body
• “First or worst” headache with meningeal signs, photophobia, or sudden onset
• Pregnant patient with fever and rigors or reduced foetal movements
• Anticoagulated patient with new neurological signs or severe headache
• Any patient where clinical gestalt says the patient may not be safe to go home — trust this, and document it

The last criterion is not in any guideline. It is in every experienced clinician’s consultation and has been cited in numerous coronial findings where a GP had a “nagging concern” but did not act on it. Document it explicitly: “Clinical concern regarding potential deterioration — [reason] — discussed with patient and carer, arranged emergency department review.”
