The Ambulance Service Dataset (ADS) will be developed over 36 months, with clinical leadership provided by the Association of Ambulance Chief Executives National Medical Directors Group, to ensure that the information collected via the ADS is the right information for patient care, and to enable a greater understanding of ambulance activity.

The ADS will contain data items related to:

• Patient demographics (gender, ethnicity, age at activity date);
• Episode information (including arrival and conclusion dates and times, source of referral and attendance category type);
• Clinical information (chief complaint, acuity, diagnosis, investigations and treatments);
• Injury information (data/time of injury, place type, activity and mechanism);
• Referred services and discharge information (onward referral for treatment, treatment complete, streaming, follow-up treatment and safeguarding concerns).
