Overview

About

Maintained by Paul GerrardCRAN page ↗

Methods to categorize ICD-9-CM codes into sensible disease categories have been developed and published by numerous authors. Two of the most widely used such methods are the Deyo adaptation of the Charlson index and the Elixhauser index. This package has functions to categorize comorbidites into the Deyo-Charlson index, the original Elixhauser index of 30 comorbidities, and the AHRQ comorbidity index of 29 diagnoses (an update to the original Elixhauser method).

Install

R (source archive)

url <- "https://cran.r-project.org/src/contrib/Archive/comorbidities/comorbidities_1.0.tar.gz"
pkgFile <- "comorbidities_1.0.tar.gz"
download.file(url, pkgFile)
install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (1.0) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.
