STUDY DESIGN: Cross-sectional study. OBJECTIVE: To evaluate the response behavior of EuroQOL-5D (EQ-5D) compared with the Oswestry Disability Index (ODI), and back and leg pain scores. SUMMARY OF BACKGROUND DATA: Recent changes in policies have highlighted the need for demonstration of both quality and cost effectiveness. In an effort to meet these requirements, surgeons are collecting health-related quality of life and utility data. Unfortunately, the burden of extensive data collection on both physician and patient is considerable. The EQ-5D is a commonly used, easily administered, brief utility measure that can provide both clinical and utility data. The EQ-5D has not yet been validated in spine patients in comparison with established outcome measures. METHODS: EQ-5D, ODI, back and leg pain (0-10) scores were collected as part of standard clinical practice. Spearman rank correlations between the ODI, back and leg pain scores, and the EQ-5D were determined. A subanalysis to determine dimension-specific effects was done. Data were categorized by level of low back disability and level of back and leg pain. RESULTS: Data from 8385 patients (5046 females, 3339 males), mean age 52 (range, 18-96) were analyzed. There was a strong correlation between EQ-5D and ODI (r = -0.776) and between EQ-5D and back pain (r = -0.648); and moderate correlation between EQ-5D and leg pain scores (r = -0.538). Increasing disability, as measured by ODI, lead to lower EQ-5D scores, with similar response behavior for both back and leg pain scores. All correlations were statistically significant at P < 0.0001. CONCLUSION: The EQ-5D correlated well with established spine outcome measures, including ODI, and back and leg pain scores. EQ-5D correlated best with ODI scores. Correlation with back pain was stronger than leg pain, but all correlations were relatively strong. The EQ-5D can serve spine surgeons as an effective measure of clinical outcome and health utility for economic analysis.
