The Charlson Comorbid score is the sum of points for all Comorbid Diagnoses that have a Charlson score associated with them.
Data Structure
The Charlson Comorbid Diagnosis codes have been mapped to the Critical Care/Medicine. See List of diagnosis codes corresponding to Charlson Comorbidities (pre ICD10). The scores were also stored in the s_AllDiagnoses table list used in CCMDB.mdb.
SAS coding macro comorbid3
The statistician has a SAS macro called "comorbid3" that calculates the score for data after import. This is important because the addition of points has exceptions for mutually exclusive dxs (eg mild and severe diabetes).
Summary: Add dx scores except following:
- score only the higher of
- diabetes vs diabetes with end organ disease
- mild liver disease vs moderate or severe liver disease
- only one count in case there are several metastatic solid tumors

queries
- s_charlson_score
sums the scores in
- s_charlson__combined
which unions (ie no duplicates)
- s_charlson_adm - list of scores for the highest-scoring admit dx per charlson category
- s_charlson_como - list of scores for the highest-scoring comorbid dx per charlson category
function Charlson_score_function
The function Charlson_score_function (Pat_ID) in CCMDB.mdb looks up and returns the score in query s_charlsonScore.
