We recommend viewing this Phenotype on the OpenCodelist website to view the most recent version.\n\n\nThis lists contains CTV3 codes used to identify people who may have had diabetes ketoacidosis (DKA). It has been generated based on a [DKA snomed list](https://codelists.opensafely.org/codelist/opensafely/diabetes-ketoacidosis-snomed-dka-unspecific/2020-10-06/) using internal mappings. The SNOMED codelistlist was conceived to identify DKA in a specific group of patients in a specific time period, therefore we have been permissive in including unspecific codes which may not be suitable for all studies.\n\n\n© University of Oxford for the Bennett Institute for Applied Data Science 2025\\.
