What is the problem?
The current Emergency Medicine data collection system does not measure inputs or outputs accurately:
- There is no universal system of triage (see Triage position statement)
- The diagnostic coding is hopeless for either clinical use or policy-making:
a) 30-40% of all visits are uncoded,
b) a further 10% are coded as symptoms e.g. ‘chest pain’
c) the remaining 50% are coded in a variety of different codesets, making communication with other healthcare providers, or service improvement near impossible.
We know that besides the increase in numbers over the last few years, there has been a corresponding increase in acuity. We cannot measure this because we have no meaningful data.
What is CEM doing about this?
The Clinical Effective Committee has been working hard to refine a Unified Diagnostic DAtaset (UDDA). This creates a bridge between to integrate ICD10, SNOMED, CDS and ‘real world’ descriptions of disease. The aim is to enable consistent coding in Emergency Departments, in a way that is easy for IT systems providers to implement.
The UDDA also allows aggregation of data to support public health (Syndromic Surveillance), audit and research.
The Information Centre of the Department of Health and Connecting for Health are working with the CEM to make the UDDA a standard for information collection.
Departments that use CDS or ICD10 to code will be migrated to use the UDDA, and departments that use SNOMED will continue to do so, but the data they produce will be able to be reduced to UDDA format.
