“…The one study that used the classification system of the non-preference-based measure without modification actually derived the non-preferencebased measure in the same study, and is therefore discussed in the section below on deriving measures 'de novo' . 45 Six papers provide a clear and detailed description of their chosen methodology, and all analysed the performance of items from the non-preference-based measure using existing data and used a selection of psychometric criteria to select a subset of items. 31,[50][51][52]58,60 Two papers also used qualitative analysis alongside the psychometric analysis.…”

“…All but four of these studies aimed to produce a QALY measure, several of which stated that they selected their valuation technique in order to enhance comparability with the EQ-5D or to comply with guidelines [96] issued by the UK National Institute for Health and Care Excellence (NICE) [23; 30; 42; 46; 47; 57; 61; 82; 84; 87; 89]. Three studies selected DCE methods to produce non-QALY instruments to inform decision analysis, stating that DCEs mirror the ways in which patients choose between treatment strategies [25; 28] or are more appropriate than SG or TTO approaches for chronic conditions where death is not a likely outcome [14]. The latter also provided a rationale for using DCEs to elicit preferences for a QALY measure [24].…”

A Systematic Review of the Literature on the Development of Condition-Specific Preference-Based Measures of Health

Background. Health state utility values (HSUVs) are required to calculate quality-adjusted life-years (QALYs). They are frequently derived from generic preference-based measures of health. However, such generic measures may not capture health attributes of relevance to specific conditions. In such cases, a condition-specific preference-based measure (CSPBM) may be more appropriate.Objective. This systematic review aimed to identify all published accounts of developing CSPBMs, to describe and appraise the methods used. Results. Eighty-six publications were identified, describing 51 CSPBMs. Around two-thirds of these were QALY measures; the remainder were designed for clinical decision-making only. Classification systems for 33 CSPBMs were derived from existing instruments; 18 were developed de novo. HSUVs for 34 instruments were estimated using a 'composite' approach, involving statistical modelling; the remainder used a 'decomposed' approach based on multi-attribute utility theory. Half of the papers that described the estimation of HSUVs did not report validating their measures.Conclusion. Various methods have been used at all stages of CSPBM development. The choice between developing a classification system de novo or from an existing instrument may depend on the availability of a suitable existing measure, while the choice between a decomposed or composite approach appears to be determined primarily by the purpose for which the instrument is designed. The validation of CSPBMs remains an area for further development. 3 Key Points for Decision MakersThere are two main approaches to developing a classification system (derivation from an existing instrument or de novo) and two main approaches to estimating health state utility values (using statistical regression or multi-attribute utility theory) for a condition-specific preference based measure.There is more evidence available to support the validity of classification systems that were derived from existing measures of health-related quality of life than there is for classification systems developed de novo.

“…The EQ-5D data obtained from 255 OAG individuals from Leeds and Aberdeen as well as members of the International Glaucoma Association were used. 277 As the degree of visual impairment with mild OAG is minimal, it was assumed that the score for those with OHT would be the same as the score for those with mild OAG. This value is comparable to the mean age group population EQ-5D score 276 that would be estimated for the model-simulated cohort age group.…”
