Comprehensive complication index (CCI)

The CCI® calculator is an online tool to support the assessment of patients’ overall morbidity. The Comprehensive Complication Index (CCI®) is based on the complication grading by Clavien-Dindo Classification and implements every occurred complication after an intervention. The overall morbidity is reflected on a scale from 0 (no complication) to 100 (death).

Clavien-Dindo grade V always results in CCI® 100, so is excluded from this calculation.
