tag_emergency_care_site 

tag_emergency_care_site(care_site: DataFrame, algo: str = 'from_mapping') -> DataFrame

Tag care sites that correspond to medical emergency units.

The tagging is done by adding a "IS_EMERGENCY" column to the provided DataFrame.

Some algos can add an additional "EMERGENCY_TYPE" column to the provided DataFrame, providing a more detailled classification.

PARAMETER DESCRIPTION
care_site

TYPE: DataFrame

algo

Possible values are:

  • "from_mapping" relies on a list of care_site_source_value extracted by Judith LEBLANC, Ariel COHEN and validated by an ER doctor. The emergency care sites are here further labelled to distinguish the different types of emergency
  • "from_regex_on_care_site_description": relies on a specific list of RegEx applied on the description (= simplified care site name) of each care site.
  • "from_regex_on_parent_UF": relies on a specific list of regular expressions applied on the description (= simplified care site name) of each UF (Unité Fonctionnelle). The obtained tag is then propagated to every UF's children.

TYPE: str DEFAULT: 'from_mapping'

RETURNS DESCRIPTION
care_site

Dataframe with 1 to 2 added columns corresponding to the following concepts:

  • "IS_EMERGENCY"
  • "EMERGENCY_TYPE" (if using algo "from_mapping")

TYPE: DataFrame

from_mapping 

from_mapping(care_site: DataFrame, version: Optional[str] = None) -> DataFrame

This algo uses a labelled list of 201 emergency care sites.

Those care sites were extracted and verified by Ariel COHEN, Judith LEBLANC, and an ER doctor validated them.

Those emergency care sites are further divised into different categories, as defined in the concept 'EMERGENCY_TYPE'. The different categories are:

  • Urgences spécialisées
  • UHCD + Post-urgences
  • Urgences pédiatriques
  • Urgences générales adulte
  • Consultation urgences
  • SAMU / SMUR

See the dataset here

PARAMETER DESCRIPTION
care_site

Should at least contains the care_site_source_value column

TYPE: DataFrame

version

Optional version string for the mapping

TYPE: Optional[str] DEFAULT: None

RETURNS DESCRIPTION
care_site

Dataframe with 2 added columns corresponding to the following concepts:

  • "IS_EMERGENCY"
  • "EMERGENCY_TYPE"
