All four procedures - groin hernia, knee replacement, hip replacement and varicose vein - have scores for the EQ-5D™ Index and EQ VAS. Hip replacement, knee replacement and varicose vein procedures each have their own condition-specific measure, which combine into a single score a patient's answers to a number of health questions of particular relevance to their procedure.
EQ‑5D™ Index
The EQ-5D™ Index collates responses given in 5 broad areas (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and combines them into a single value. The EQ-5D™ Index was developed by the EuroQol Group. EQ-5D™ is a trademark of the EuroQol Group.
EQ Visual Analogue Scale (EQ VAS)
EQ VAS is a simple and easily understood 'thermometer'-style measure based on a patient's self-scored general health on the day that they completed their questionnaire, but which provides an indication of their health that is not necessarily associated with the condition for which they underwent surgery and which may have been influenced by factors other than healthcare. The EQ VAS was developed by the EuroQol Group.
Oxford Hip Score (OHS)
The OHS contains 12 questions on activities of daily living that assess function and residual pain in patients undergoing total hip replacement surgery. The OHS was designed, developed and validated by workers within public health and at the University of Oxford.
Oxford Knee Score (OKS)
The OKS contains 12 questions on activities of daily living that assess function and residual pain in patients undergoing total knee replacement surgery. The OKS was designed, developed and validated by workers within public health and at the University of Oxford.
Aberdeen Varicose Vein Questionnaire (AVVQ)
The AVVQ allows patients to self-assess the severity of their varicose veins via a 13-item measure covering all aspects of their varicose veins including physical symptoms such as pain, ankle oedema, ulcers, the effect on daily activities, and cosmetic issues.
Use of the AVVQ was discontinued in October 2017 with the removal of the collection of varicose vein questionnaires as part of the response to the NHS England PROMs consultation*
