Ambulance Service Indicators

AUGUST 2023 Update: An error in the STEMI technical specification has created an associated case / compliance anomaly.  The specification has been corrected and associated coding updated.  ASI STEMI data has been re-run and updated accordingly back to August 2022. This updating shows a step change downwards in the number of cases with an increase in overall compliance. 


The Ambulance Services Indicators are now published on a monthly rather than on a quarterly basis, below you will find an interactive dashboard following the 5-Step Ambulance Model:

  • Step 1: Help me choose
    • Welsh Ambulance Services NHS Trust & NHS 111 Wales Telephony and Website data
  • Step 2: Answer my call
    • Initial (emergency call handler) and advanced (clinical) call triage including frequent caller data
    • Incident trend over time by category, both service and Medical Priority Dispatch System Protocols
  • Step 3: Come to see me
    • Incident category breakdown by Local Health Board including Community and Uniformed Responder data
    • Incident response data by categorisation (RED, AMBER, GREEN) 
    • RED performance (ambulance resource arrival within 8 minutes 65% of the time for life-threatening emergencies)
  • Step 4: Give me treatment
    • Incidents resulting in a non-conveyance to hospital
    • Clinical Indicators* covering Cardiac Arrest: Return of Spontaneous Circulation (ROSC), Stroke, SEPSIS, STEMI, Febrile Convulsion, Hypoglycaemia and Fractured hip
  • Step 5: Take me to hospital
    • Incidents resulting in a conveyance to hospital by hospital type
    • Resource notification of arrival to patient handover
    • Resource availability after patient handover 
    • Lost hours following handover waits

* Clinical Indicator collection and reporting has changed following the introduction of an Electronic Patient Clinical Record (ePCR) within the Welsh Ambulance Services NHS Trust and was suspended in December 2021 to allow the rollout of the ePCR, as such no clinical indicator data is reported For December 2021, January, February and March 2022. From April 2022 clinical indicator data for Stroke, ST-elevation myocardial infarction (STEMI), Hypoglycaemia and Fractured Neck of Femur has been published with other clinical indicators coming on line following quality checks and assurance.
