As described in the specification guidance document mentioned above, calls made to NHS 111 are not included in the AQI measures for calls abandoned (SQU03_1_1), re-contacts (SQU03_2_1 and SQU03_2_2), frequent callers (SQU03_2_3), time to answer calls (SQU03_8_1_1) and calls resolved by telephone advice (SQU03_10_1). All other Systems Indicators involve the dispatch of an ambulance, and include ambulances dispatched as a result of a call to NHS 111, as well as 999 or 112. C4 Related statistics in England The AQI appear in a Clinical Dashboard, available from the AQI landing page, the websites of the Ambulance Trusts (listed in the AQI Quality Statement), and . One of the aims of these Dashboards is to use statistical process control, to indicate whether variation in proportions reflects underlying change, or merely natural variance, unavoidable even when a health system is performing well.
