Health Informatics is the internationally recognised and Department of Health term covering the use of resources, devices, and methods required to optimize the acquisition, storage, retrieval, and use of information in health and biomedicine. The number of Emergency Department attendances has been increasing rapidly over the last few years, which has focused attention on why this has occurred. 

The Royal College of Emergency Medicine Informatics page features Informatics information and resources including: clinical records, emergency care data set, informatics (and introduction), summary care record and syndromic surveillance.

Emergency Care Data Set (ECDS)

The Royal College of Emergency Medicine has been working with NHS England, NHS Digital and other key system partners to develop and implement a new data set to collect Emergency Department activity information.

The new data set, CDS Type 011 – ECDS will replace the current A&E Commissioning Data Set with a data set that can properly capture and represent the full extent and granularity of ED activity across England. 

The ECDS is based on previous work completed by the college to develop the Minimum Data Set for Emergency Care (MDEC) and the Unified Diagnostic Data Set (UDDA). Documentation related to both the MDEC and UDDA has been removed from the college web site as it is superseded by the ECDS project documentation.  

ECDS development from 2016-2017 has been led by the colleges Informatics Committee and we are pleased to announce that the data set was approved an Information Standard Notice (ISN) on the 19th April 2017.

For further information regarding the ECDS please refer to the NHS Digital ECDS website (
