Communication from the Royal College of Emergency Medicine (RCEM)

As part of our commitment to getting information to you quickly during the pandemic, we’ve been asked to urgently share with you information about how to code cases of COVID-19 in your IT systems. We’ve had a number of questions from Members and Fellows about this and so are sharing this guidance with you to assist. Please feel free to pass this on to relevant personnel.

Guidance endorsed by the College’s Informatics Committee

If your hospital has not already implemented a system of recording COVID and submitting it centrally as part of ECDS the recommended options are: 

1240751000000100 - Disease caused by 2019-nCoV (novel coronavirus) [UK SNOMED code]

This data should be submitted as part of ECDS either as the normal diagnosis list (suspected / confirmed) and/or using the ECDS 'disease outbreak notification' field (this is limited to 20 characters so just submit the code). 

Please note: some IT providers may not have made the disease outbreak notification field visible to users but it is part of the original ECDS specification from April 2017.

Read the full guidance from RCEM.

ECDS data quality summary report

Is an interactive data quality report providing early analysis between providers and for individual SNOMED CT codes: primary diagnosis; treatment; investigation and chief complaint. 

The Emergency Care Data Set data quality reports on the following:  

  • percentage of each SNOMED code highlighting which are the most common codes nationally
  • field validity for each provider organisation
  • from May 2019 activity, a new tab for each of these four fields has been added to report the number of different, unique codes submitted by each provider.  Providers with a low number of unique codes indicates that the full ECDS SNOMED_CT functionality isn’t being utilised, losing granularity that the ECDS dataset has to offer.

Retirement of deprecated SNOMED CT Codes

We have now placed end-dates on any codes that are no longer used, so they will be flagged as invalid for activity dated after 31/3/2019. Please ensure you check your local setup to ensure it only contains SNOMED codes presented in Enhanced Technical Output Specification v2.1.1.1 (see below).

SNOMED codes that have been deprecated (those that do not appear in v2.1.1.1 of the E TOS) will no longer be accepted as valid codes for submission to SUS+ for activity dated later than 31/3/2019.
