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).
