To assess the appropriateness of the EQ-5D in 13 specified conditions (inflammatory bowel disease (IBD), epilepsy, diabetes, bowel cancer, head and neck cancer, psychological therapies, schizophrenia, dementia, cardiac arrhythmia, heart failure, coronary angioplasty, acute coronary syndrome, adult cardiac surgery); identify what measures may be used when the EQ-5D is not appropriate; identify if fields in corresponding National Clinical Audits (NCA) will suffice to conduct economic evaluations; present recommendations and future research questions in this area.
