The Emergency Care Data Set (ECDS) is the national data set for urgent and emergency care. It replaced Accident & Emergency Commissioning Data Set (CDS type 010) and was implemented through ECDS (CDS 6.2.2 Type 011).

ECDS allows NHS Digital to provide information to support the care provided in emergency departments by including the data items needed to understand capacity and demand and help improve patient care.

All the ECDS data quality reports on this page are classified as experimental data. 

This data quality interactive report shows the frequency of ECDS submissions to SUS (Secondary Uses Service) to provide greater insight monitor progress as providers move to submit daily. It also displays the completeness/validity percentage for 20 fields within ECDS, by provider organisation.

This data quality interactive report provides early analyses using data submitted from the ECDS to compare data between providers (provider organisation, department type and month) four key fields: chief complaint, clinical Investigation, first diagnosis code and treatment code.

This report is updated monthly, as per the Provisional Monthly Accident and Emergency for England calendar for the financial year 2021-22. 

The Excel tabulation report below includes breakdowns of the key fields’ SNOMED CT values. It also reports activity counts being submitted by provider, and how these counts relate to previous months. These counts are reported separately between department types 1&2 and 3&4:
