Health and Well-Being

Lead Research Organisation: MRC Health Services Resrch Collaboration

Abstract

Given the scarcity of resources in the NHS, it is important to examine the value for money (or cost effectiveness) of health services. This involves examining whether a treatment works, what the benefits are to patient s and what are the costs. This programme of work is concerned with the middle of these, which how do we assess the benefit to patients. A key measure of patient benefit used in assessing cost effectiveness has been the Quality Adjusted Life Year (QALY), which values health related quality of life on a scale from zero to one, where zero is for states regarded as bad as being dead and one for states that are in full health. ||The key problem has been how to come up with this value from zero to one. The dominant method for doing this in recent years has been to use a measure called a generic preference-based measure (such as the EQ-5D). However, there are many concerns existing methods, including how we describe health and well-being, how we derive the value and who should do the valuing. This programme is concerned with addressing these questions by undertaking an number of interconnected studies looking at different ways to describe health, different valuation methods and comparing the values of different people. It is also examining the way health impacts on peoples overall well-being or quality of life and trying understanding the role of mechanisms like coping. ||This programme should help to improve the methods used to value benefits and so provide better information to people deciding what services to provide in the NHS with its scarce resources.||

Technical Summary

The aim of this programme is to develop methods in the measurement and valuation of the benefits of health care. Its specific objectives are to address the key concerns of measuring QALYs, including: what is being valued (e.g. health or well-being); how is it to be described (e.g. which generic and generic vs. a measure specific to the treatment, condition or programme); how to value it (e.g. SG vs. TTO and the role of ordinal methods such as ranking and DCE); and whose values (e.g. patients or the general public).||Programme of work ||1) Develop methods in the construction and valuation of preference-based measures. ||2) Designing of measures in Children (Katherine Stevens -MRC Fellow), mental health (Caroline Lee-Abrahams - MRC HSRC Studentship), and a range of specific conditions (including Asthma, Overactive Bladder and sexual health) ||3) Examining the potential of ordinal methods to value health states. Specific work has included the valuation of generic and condition specific measures using rank and DCE data. Recently the PI has obtained an ward from the MRC Methodology and Implementation Programme to use ordinal methods of preference elicitation to map between measures in order to facilitate evidence synthesis ||4) Modelling health state data. Collaboration with Professor O Hagan and Dr. Kharroubi to develop a Bayesian method to model preference data. ||5) Examine the relationship between health and well-being. An analysis of a large cross sectional data set containing measures of health (EQ-5D/SF-36) and wellbeing. Survey of the general population using measures of health and well-being. MRC Studentship undertaking a mixed methods study of patients on waiting lists for knee replacement and Cataract operations to examine the role of coping and other psychological mechanisms in explaining the variation in the impact of health on well-being ||6) Mental health Review the use of generic measures in mental health. PhD student currently looking at developing a preference-based measure from the CORE Develop a preference-based mental health measure - currently at a proposal stage||This programme started in November 2004 with the funding of the PI and 2 studentships, otherwise it relies on grants from a range of bodies including the MRC, NHS HTA and pharmaceutical companies.||
