Phenotyping based on ICD-10 codes.

PARAMETER DESCRIPTION
condition_occurrence

condition_occurrence OMOP DataFrame.

TYPE: DataFrame

visit_occurrence

visit_occurrence OMOP DataFrame, only necessary if date_from_visit is set to True.

TYPE: Optional[DataFrame] DEFAULT: None

codes

Dictionary which values are ICD-10 codes (as a unique string or as a list) and which keys are at least one of the following:

  • exact: To match the codes in codes["exact"] exactly
  • prefix: To match the codes in codes["prefix"] as prefixes
  • regex: To match the codes in codes["regex"] as regexes You can combine any of those keys.

TYPE: Dict[str, Union[str, List[str]]] DEFAULT: None

date_from_visit

If set to True, uses visit_start_datetime as the code datetime

TYPE: bool DEFAULT: True

additional_filtering

An optional dictionary to filter the resulting DataFrame.

Keys should be column names on which to filter, and values should be either

  • A single value
  • A list or set of values.

TYPE: Dict[str, Any] DEFAULT: dict(condition_status_source_value={'DP', 'DAS'})

date_min

The minimum code datetime to keep. Depends on the date_from_visit flag

TYPE: Optional[datetime] DEFAULT: None

date_max

The minimum code datetime to keep. Depends on the date_from_visit flag

TYPE: Optional[datetime] DEFAULT: None

RETURNS DESCRIPTION
DataFrame

"event" DataFrame including the following columns:

  • t_start: If date_from_visit is set to False, contains condition_start_datetime, else contains visit_start_datetime
  • t_end: If date_from_visit is set to False, contains condition_start_datetime, else contains visit_end_datetime
  • concept : contaning values from codes.keys()
  • value : The extracted ICD-10 code.
  • visit_occurrence_id : the visit_occurrence_id from the visit which contains the ICD-10 code.
