It incorporates thirty comorbid conditions and has been validated in acute-care inpatient hospital settings using administrative data. The Elixhauser Comorbidity Index Score (ECIS) is another popular comorbidity assessment method introduced by Elixhauser et al. CCIS has been used previously to assess medical comorbidity in the schizophrenic population. CCIS has been modified in several ways including by a reduction in the number of conditions considered from 19 to 17 and the use of coding by specific International Classification of Diseases, Clinical Modifications (ICD-CM) diagnosis codes. The CCIS has been used extensively to evaluate the impact of comorbid conditions in a variety of conditions. The weight assigned to each comorbid condition ranged from one to six and the individual score for each of these conditions contributed to the final score. in 1987 by reviewing hospital charts and assessing their relevance to one-year mortality. The Charlson Comorbidity Index Score (CCIS), calculated based on 19 comorbid conditions, was developed by Charlson et al. Its use may be encouraged for risk adjustment in this population.

ECIS had better discriminative performance in mortality risk than CCIS in patients with schizophrenic disorders. Both ECIS and CCIS were significantly associated with mortality, but ECIS had superior discriminatory ability by a lower AIC and higher Harrell’s C-statistic (201231 vs. We identified 58,771 discharged patients with schizophrenic disorders and followed them for a mean of 10.4 years, 16.6% of whom had died. Discriminatory ability was evaluated using the adjusted hazard ratio and Akaike information criterion (AIC) and Harrell’s C-statistic.

Comorbidities presented one year prior to hospital admissions were identified and adapted to the CCIS and ECIS. They were followed up for subsequent death. Exploiting Taiwan’s National Health Insurance Research Database (NHRID), we identified patients diagnosed with schizophrenia discharged from hospitals between and Dec 31, 2007. This nationwide retrospective study investigated discriminative performance of mortality of these two scales in patients with schizophrenia. Although Charlson Comorbidity Index scores (CCIS) and Elixhauser comorbidity index scores (ECIS) have been used to assess comorbidity in patients with schizophrenia, only CCIS, not ECIS, have been used to predict mortality in this population.
