The Charlson Comorbidity Index is a method of classifying prognostic comorbidity in longitudinal studies.
Some Comorbid Diagnosis have points associated with them that contribute to an overall comorbidity score. This score reflects the cumulative increased likelihood of one year mortality.
Structure
Contains 19 primary medical conditions of comorbidity some of which contain subcategories of diseases related to the primary category. For a list of all diagnosis applicable that we use go to: Charlson Comorbid Diagnosis (or Comorbid_Disease-General_Information#Comorbid_List as former may not include all sub-diagnoses).
ICD10
- Concept:ICD10 Charlson Comorbidity - ICD10 diagnoses with Charlson scores
Collection Start Date
September 14, 1998
Data Use
- MOST score for Medicine
- Some items are use for APACHE II score for Critical Care. For a specific list of chronic condition applicable to APACHE II scoring see: Chronic Health APACHE
- Template:Discussion is this used in Reporting? If so, which? Ttenbergen 01:25, 2017 September 23 (CDT)
Background
The Charlson Index was developed in 1987 based on 1-year mortality data from internal medicine patients admitted to a single New York Hospital and was initially validated within a cohort of breast cancer patients. The index encompasses 19 medical conditions weighted 1–6 with total scores ranging from 0–37. In the development phase of the index, mortality for each disease was converted to a relative risk of death within 12 months. A weight was then assigned to each condition based on the relative risk (RR); for example,
- RR <1.2 = weight 0,
- RR ≥ 1.2<1.5 = weight 1,
- RR ≥ 1.5<2.5 = weight 2,
- RR ≥ 2.5<3.5 = weight 3,
- and for 2 conditions (metastatic solid tumor and AIDS) = weight 6.
From the weighted conditions, a sum score can be tallied to yield the total comorbidity score.
