Description

These lists provide correctly sorted names of the comorbidities and their particular permutations in both full and abbreviated forms.

Format

list, with character/numeric code. 'Hypertension, uncomplicated' and 'Hypertension, complicated' are labelled '6a' and '6b'. Diabetes, cancer, and metastasis are counted independently, as in the original paper, giving the original 30 groups. "01" to "30"

Details

In the Elixhauser derived mappings, uncomplicated and complicated hypertension are listed separately, but are always combined in the final analyses. Uncomplicated and complicated hypertension are list separately and as "Hypertension, combined." _abbrev suffix indicates a very short space-free description. Quan's version of Elixhauser is identical. AHRQ updates drops the arrythmia field. The naming convention is a root, e.g. icd9_map_elix or icd10_map_elix, with neither/either/both suffixes _htn and _abbrev. The Charlson derived mappings do not include hypertension. _abbreviated comorbidity names are helpful for interactive work, whereas the full names might be preferred for plotting.
