Analysis Normal Form (ANF)
Analysis Normal Form (ANF) is a standardized, encoded, and machine-processable representation of clinical statement that is intended to safely and reliably support data analysis that can be used to aggregate data created using any standard or non-standard input form or exchange mechanism. ANF seeks to address the variability of how clinical data within value sets and Clinical Decision Support (CDS) rules are modeled and stored in data repositories.
In August 2019, ANF was submitted to HL7 for an Informative Ballot. Results will be announced in October 2019. You can view a copy of this submission here.
For more information on ANF, please refer to this presentation that will provide an overview.
