CKD[source]

The eds.CKD pipeline component extracts mentions of CKD (Chronic Kidney Disease). It will notably match:

Mentions of various diseases (see below)
Kidney transplantation
Chronic dialysis
Renal failure from stage 3 to 5. The stage is extracted by trying 3 methods:
- Extracting the mentioned stage directly ("IRC stade IV")
- Extracting the severity directly ("IRC terminale")
- Extracting the mentioned GFR (DFG in french) ("IRC avec DFG estimé à 30 mL/min/1,73m2)")

Details of the used patterns

# fmt: on

Extensions

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

span._.detailed_status: set to None
span._.assigned: dictionary with the following keys, if relevant:
- stage: mentioned renal failure stage
- status: mentioned renal failure severity (e.g. modérée, sévère, terminale, etc.)
- dfg: mentioned DFG
