Abstract

We aimed to provide a simple, descriptive health-status profile for cancer patients with bone metastases, based on the EuroQol EQ-5D, a tool commonly used to measure health utility scores, and to evaluate its association with the Brief Pain Inventory (BPI), a legacy pain-assessment tool. Although pain is one of five health-status dimensions measured by the EQ-5D, our understanding of how pain relates to the other EQ-5D dimensions is limited. We derived data from 5500 patients with bone metastases who completed the EQ-5D and BPI. Regression analyses examined how BPI severity and interference scores correlated with EQ-5D utility scores and how BPI items associated with EQ-5D items, for the entire sample and by disease-type subgroup. Regardless of cancer site, the percentage of patients reporting moderate/severe problems in each of the five EQ-5D dimensions were pain/discomfort, 78%; usual activities, 58%; mobility, 55%; anxiety/depression, 57%; and self-care, 26%. BPI pain interference explained more of the variability in the EQ-5D utility scores than did pain severity (R2 = 41% vs. 34%). BPI worst pain, average pain, pain now, interference with general activity, and interference with work significantly predicted EQ-5D pain/discomfort, with odds ratio estimates ®.
