Abstract:

The Total Illness Burden Index is a comprehensive summary measure of case mix or  severity of illness that aggregates all of the patients’ conditions, problems, and diseases, weighting them by their severity. The TIBI offers advantages over other methods of case mix measurement because it (1) is based on clinical information beyond the simple presence or absence of specific diagnoses, (2) is scored using a psychometric approach that avoids reliance on any single variable, (3) predicts health related quality of life and mortality events five or more years in the future, (4) is feasible, utilizing patient report over administrative data while requiring less than 15 minutes to complete, and (5) can be adapted based on the clinical context to assess  comorbidity with respect to a selected index condition, or to assess total morbidity from all of the patient’s conditions.

These features allow the measure to be applied in clinical settings among patients facing real-time treatment decisions and for risk adjustment in research on a wide range of medical outcomes.
