Why chest pain triage
Why chest pain triage needs better tools
Assessing chest pain can involve blood tests and observation. Clinicians need timely information to assess risk and decide the next step.

Decisions across care settings
Clinicians need to assess risk and decide the next step in emergency departments, primary care and rural clinics.

Emergency departments
Emergency departments assess chest pain while balancing urgent cases, observation capacity and demand for testing.

Primary care
Clinicians assess symptoms, identify red flags and decide whether further investigation or referral is needed.

Rural clinics
Limited access to investigations and specialist advice can make transfer decisions more difficult.
