A model to estimate health utilities index mark 3 utility scores from WOMAC index scores in patients with osteoarthritis of the knee.

Abstract

A formula was derived from the WOMAC index to estimate overall utility scores based on the HUI3 for studies of patients with OA for whom utility has not been recorded. Researchers can estimate overall utility scores, compute quality-adjusted life-years, and perform cost-utility analyses within a defined range of certainty.
