Data Quality and Coding Rules
Kent Spackman – Chair of the SNOMED International Editorial Board – expounded two new rules in his Tutorial for the SNOMED User Group in Chicago today:
1. The First Rule of Data Quality is that the quality of data collected is directly proportional to the care with which options are presented to the user.
2. The First Rule of Coding is that yesterdays data should be usable today.
He explored these rules by considering the challenges and obstacles involved in using SNOMED CT for creating Problem Lists, Medication Lists and Medication Allergy decision support. And he showed that the key to making this work properly is the skillful use of SNOMED CT Subsets and the appropriate use of Post-coordinated concepts.
Subsets are lists of SNOMED concepts for a specific purpose.
Post-coordination is the ability to link concepts together to create more complex ones, using qualifying relationships such as body site, laterality or severity.
