This is the actual operational layer on top of everything above β it decides the destination and whether RED Stroke Standby applies, before any hospital team even gets involved.
FAST positive β query stroke
If in line with JRCALC guidelines, consider HASU. Alternatively, Clinical Incident Hub for advice (Advanced Paramedic, callsign CH183).
< 9 hours since LKW
β Nearest Hyper-Acute Stroke Unit
9β48 hours since LKW
β Nearest Hyper-Acute Stroke Unit
Over 48 hours since LKW
β Transport to local ED
Exception: Cheshire & Mersey area β suspected stroke patients still go to nearest HASU.
FAST negative, query stroke / Query TIA
β Follow NWAS clinical procedures β local ED
Exception: Cheshire & Mersey β suspected TIA patients attend nearest HASU.
GM only β on anticoagulation (rivaroxaban, edoxaban, apixaban, warfarin or similar)
Yes β RED Stroke Standby. Use ASHICE, include name and DOB.
No β No pre-alert needed.
Downstream effect: The 9-hour and 48-hour cutoffs aren't the thrombolysis 4.5h window itself β they're the destination-triage cutoffs NWAS uses to decide whether the patient needs the HASU's hyperacute capability at all, vs a local ED. Inside 9h, the patient may still be a thrombectomy/thrombolysis candidate by the time imaging is done, so the nearest HASU keeps every option open. The anticoagulation trigger for RED Stroke Standby exists specifically because GM HASUs want advance warning to have reversal agents and imaging slots ready β it's the same logic as the bleeding-risk exclusion, just applied earlier, at dispatch.
Pathway exclusions (these patients don't follow this stroke pathway β manage per usual NWAS procedures and transport to nearest appropriate ED):
- Age < 16
- A β Airway requiring intervention
- B β Assisted breathing using IPPV/BVM ventilation
- C β Hypotension/bradycardia unresponsive to treatment
- D β GCS 7 or less, BM <4.0
- Any seizure activity reported during or causing the event

Treatment considerations on scene
- "Time is Brain" β minimise on-scene time, target <15 minutes
- Cannulate unaffected arm if clinically appropriate
- Bring a witness to accompany the patient where possible
- Document last seen well time if onset is not known
- Patient kept nil by mouth
- 12-lead if clinically appropriate, document any irregular heart rate β not required to diagnose stroke, don't delay on scene for it
