Alcohol consumption

The eds.alcohol pipeline component extracts mentions of alcohol consumption. It won't match occasional consumption, nor acute intoxication.

Extensions

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

span._.detailed_status: set to either
- "PRESENT"
- "ABSTINENCE" if the patient stopped its consumption
- "ABSENT" if the patient has no alcohol dependence

Examples

import edsnlp

nlp = edsnlp.blank("eds")
nlp.add_pipe("eds.sentences")
nlp.add_pipe(
    "eds.normalizer",
    config=dict(
        accents=True,
        lowercase=True,
        quotes=True,
        spaces=True,

)

The eds.alcohol 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.
