map_charlson_comorbidities: Map ICD-10 to Charlson comorbidities and weights

In ramses-antibiotics/ramses-package: R Package for Antimicrobial Stewardship & Surveillance

Map ICD-10 to Charlson comorbidities and weights

Description

Map ICD-10 or ICD-10-CM codes to a list of chronic comorbidities, comorbidity groups, and Charlson Comorbidity Index weights from \insertCiteQuan2005;textualRamses.

Usage

map_charlson_comorbidities(df, icd_column)

Arguments

df	a data frame containing ICD-10 look up data
icd_column	a variable name or column number in df containing ICD-10 codes.

Value

The input data frame df enhanced with the following variables:

• comorb a character vector of 17 comorbidity codes (adapted from the comorbidity package)

• comorb_group a character vector of codes grouping comorb codes into 14 categories collapsing different severities of the same condition (for diabetes, liver disease, cancer). This is to avoid double counting comorbidities.

• charlson_weights an integer vector of weights from \insertCiteQuan2005;textualRamses used to compute the weighted Charlson comorbidity score
