Comparison of the underlying constructs of the EQ-5D and Oxford Hip Score: implications for mapping.

Abstract

OBJECTIVES: Both disease-specific and generic patient-reported outcome measures provide information about the health status of patients. Generally, disease-specific measures provide more clinical information than generic measures but do not provide a utility weight. The aim of this study was to assess the comparability of the information captured by a disease-specific measure, the Oxford Hip Score (OHS), and a generic measure, the EQ-5D, and the viability of mapping between them to obtain utilities for the OHS. METHODS: Data for 439 National Health Service patients in England before and 6 months after undergoing total hip replacement were analyzed. The information provided by the OHS and EQ-..
