CKD
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)")

Extensions
On each span span
that match, the following attributes are available:
span._.detailed_status
: set to Nonespan._.assigned
: dictionary with the following keys, if relevant:stage
: mentioned renal failure stagestatus
: mentioned renal failure severity (e.g. modérée, sévère, terminale, etc.)dfg
: mentioned DFG
