Mapping EQ-5D-3L from the Knee Injury and Osteoarthritis Outcome Score (KOOS).

ABSTRACT:

Purpose

To develop a mapping model to estimate EQ-5D-3L from the Knee Injury and Osteoarthritis Outcome Score (KOOS).

Methods

The responses to EQ-5D-3L and KOOS questionnaires (n = 40,459 observations) were obtained from the Swedish National anterior cruciate ligament (ACL) Register for patients ≥ 18 years with the knee ACL injury. We used linear regression (LR) and beta-mixture (BM) for direct mapping and the generalized ordered probit model for response mapping (RM). We compared the distribution of the original data to the distributions of the data generated using the estimated models.

Results

Models with individual KOOS subscales performed better than those with the average of KOOS subscale scores (KOOS₅, KOOS₄). LR had the poorest performance
