** [[Charlson Comorbidity scoring in pre-ICD10 codes]]

=== ~~Inclusion of Age~~ ===

=== We do not include an age factor ===

* The original Charlson ~~uses~~ an age factor.

The original Charlson paper optionally mentions an age factor. We do not use it. Confirmed with Dr. Garland and Dr. Roberts 2025-06-19.

* There is a note in [[Centralized_data_front_end.~~accdb_Change_Log_2019#2019~~-03-~~21]] that I deleted a query relating to that because ''we'' don't use the age factor~~.

* I ''think'' I had an age factor in the [[Overstay Predictor Project Algorithm]] (it used function Charlson_score(), and I think it is older than our detailed wiki change management)

* Do we ever include the age in the Charlson score? Should we? If not, we need to clearly document that, since others looking at this score would expect us to use the original definition. [[User:Ttenbergen|~~Ttenbergen]] 11:03, 28 January~~ 2025 ~~(CST)~~
