Utility of the Chronic Disease Score and Charlson Comorbidity Index as Comorbidity Measures for Use in Epidemiologic Studies of Antibiotic-resistant Organisms

Charlson Comorbidity Index

Charlson Index comorbidity adjustment for ischemic stroke outcome studies.

BACKGROUND AND PURPOSE The Charlson Index is commonly used in outcome studies to adjust for patient comorbid conditions, but has not been specifically validated for use in studies of ischemic stroke. The purpose of the present study was to determine whether outcomes of ischemic stroke patients varied on the basis of the Charlson Index. METHODS The Department of Veterans Affairs (VA) Stroke St...

Charlson comorbidity index adjustment in intracerebral hemorrhage.

BACKGROUND AND PURPOSE Previous studies of intracerebral hemorrhage (ICH) outcome prediction models have not systematically included adjustment for comorbid conditions. The purpose of this study was to assess whether the Charlson Comorbidity Index (CCI) was associated with early mortality and long-term functional outcome in patients with intracerebral hemorrhage. METHODS We performed a retros...

The use of Charlson comorbidity index for patients revisiting the emergency department within 72 hours.

BACKGROUND To validate the use of the Charlson Comorbidity Index (CCI) for predicting admission of patients revisiting the Emergency Department (ED) within 72 hours. METHODS Non-trauma patients aged above 17 years old who revisited an urban ED within 72 hours during January of 2004 were included in this retrospective observational study. Demographic data, diagnosis, CCI, in-hospital mortality...

Modified Charlson comorbidity index for predicting survival after liver transplantation.

The benefit of liver transplantation (LT) is determined not only by the severity of illness, but also by the likelihood of posttransplantation survival. Current models are unable to accurately predict which patients will have the best posttransplant survival. We hypothesized that the Charlson Comorbidity Index (CCI), which includes nine comorbidities, could be used to predict survival after LT....
