Abstract
This study seeks to validate the conversion of PROMIS-GH scores to EQ-5D Health Utility Index (HUI) values. Patients undergoing lumbar spine surgery were prospectively surveyed using EQ-5D-3L and PROMIS-GH short form instruments. EQ-5D-HUI scores, and PROMIS scores converted to HUI were calculated. Neither instrument demonstrated any floor effects. The EQ-5D-HUI demonstrated significantly higher ceiling effects. Patients reported a significantly higher mean HUI score using the EQ-5D compared to PROMIS-GH. Strong positive correlation and agreement were observed. Conversion of the PROMIS-GH to the EQ-5D-HUI appears to be viable for evaluating the health status of patients undergoing lumbar spine surgery.
