Comparison of Charlson comorbidity index with SAPS and APACHE scores for prediction of mortality following intensive care.
Physiology-based severity of illness scores are often used for risk adjustment in observational studies of intensive care unit (ICU) outcome. However, the complexity and time constraints of these scoring systems may limit their use in administrative databases. Comorbidity is a main determinant of ICU outcome, and comorbidity scores can be computed based on data from most administrative databases. However, limited data exist on the performance of comorbidity scores in predicting mortality of ICU patients. ⋯ The CCI combined with administrative data predict short- and long-term mortality for ICU patients as well as physiology-based scores.
