Extensions

On each span span that match, the following attributes are available:

span._.detailed_status: set to either
- "WITH_COMPLICATION" if the diabetes is complicated (e.g., via organ damages)
- "WITHOUT_COMPLICATION" otherwise
span._.assigned: dictionary with the following keys, if relevant:
- type: type of diabetes (I or II)
- insulin: if the diabetes is insulin-dependent
- corticoid: if the diabetes is corticoid-induced

nlp = edsnlp.blank("eds")

Authors and citation

The eds.diabetes component was developed by AP-HP's Data Science team with a team of medical experts. A paper describing in details the development of those components is being drafted and will soon be available.
