Measuring comorbidities often involves the use of various indices and scales. One common tool is the [Charlson Comorbidity Index](href), which predicts the ten-year mortality for a patient who may have a range of comorbid conditions. Another widely used measure is the [Cumulative Illness Rating Scale](href), which assesses the burden of chronic medical illness. These tools help in quantifying the impact of comorbidities on patient health and healthcare systems.
