Correlation between clinical complexity/multimorbidity and mortality
Correlation between clinical complexity/multimorbidity of the hospitalized internal medicine patient, defined by the Cumulative Illness Rating Scale (CIRS), and mortality. Cumulative Illness Rating Scale: severity index (minimum value is 1, maximum value is 5), comorbidity index (minimum value is 0, maximum value is 13). Higher scores mean worse outcome.
