Charlson Comorbidity Index (CCI)

Purpose of the measure

The Charlson Comorbidity Index (CCI) assesses comorbidity level by taking into account
both the number and severity of 19 pre-defined comorbid conditions. It provides a weighted
score of a client’s comorbidities which can be used to predict short- and long-term
outcomes such as function, hospital length of stay and mortality rates. The CCI is the
most widely used scoring system for comorbities used by researchers and clinicians
(Charlson, Pompei, Ales, & Mackenzie, 1987; Elixhauser, Steiner, Harris, &
Coffey, 1998).
