Extensions

On each span span that match, the following attribute is available:

span._.global_health_status: set to None.

It will specify the severity of the mention regarding the general status of the patient.

Possible values are:

healthy : this span suggests the patient is well regarding that domain.
altered_nondescript : this span suggests the patient is not well, but it is not yet possible to ascertain the degree of alteration.
altered_mild : this span suggests a light alteration regarding this domain.
altered_severe : this span suggests a severe alteration regarding this domain.
other : this span is not indicative of the level of alteration regarding this domain. Still, it hints that this domain has been evaluated.
