Re: st: Charlson ado

[sebastian baumeister <baumeister.sebastian@web.de>]

Hi Jesse:

Charlson.ado is based on the paper by Quan et a. (2005) Coding algoriths
for defining comorbidities in icd-9-cm and icd-10 administrative data.
Med Care, 43: 1130-39. This paper only includes the enhanced ICD-9-CM
diagnosis codes.

Regards,
Sebastian
