Get Elixhauser Codes

Retrieve copy of internal lookup tables for the ICD codes used in assessing Elixhauser comorbidities.

Usage

get_elixhauser_codes()

Value

A data.frame with the following columns:

• icdv: Integer vector indicating if the code is from ICD-9 or ICD-10

• dx: Integer vector. 1 if the code is a diagnostic, (ICD-9-CM, ICD-10-CM, WHO, CDC Mortality), or 0 if the code is procedural (ICD-9-PCS, ICD-10-PCS)

• full_code: Character vector with the ICD code and any relevant decimal point

• code: Character vector with the compact ICD code omitting any relevant decimal point

• condition: Character vector of the conditions

• elixhauser_<variant>: Integer vector indicating if the code is part of the <variant> of the Elixhauser comorbidities.

See also

• get_elixhauser_index_scores() for the lookup table of the condition by condition scores for mortality and readmission indices.

• get_elixhauser_poa() for the lookup table of the conditions which do an do not require associated ICD codes to be present-on-admission to flag the comorbidity.

• get_icd_codes() for the lookup table of all ICD codes.

• get_pccc_codes() for the lookup table of ICD codes used for the PCCC.

• get_charlson_codes() for the lookup table of ICD codes used for the Charlson comorbidities.

• comorbidities() for applying comorbidity algorithms to a data set.
