Abstract: The Cerebral Palsy quality of life instrument is a well-known health-related quality of life measure for children with Cerebral Palsy. Due to its length it is not suitable as the basis of a preference-based instrument. The aim of this study is to develop a short version of the Cerebral Palsy quality of life instrument that can subsequently be scored as a multi-attribute utility instrument through assigning preference-based values. A s le of 473 participants who have a child with Cerebral Palsy completed the Cerebral Palsy quality of life instrument(proxy-version) instrument. After deleting questions related only to the proxy, the dimensional structure was obtained using exploratory factor analysis. Extended Rasch analysis was then undertaken to test the psychometric performance of items and select the best item to represent each dimension. Expert opinion was sought to confirm the dimensions and items. A six-dimension classification system was identified, in which four domains were extracted from the factor analysis. Following expert opinion, two other domains were also added, as these were considered to have significant impact on health-related quality of life in children with Cerebral Palsy. The combination of Factor and Rasch analysis along with consultation with patients, clinicians and experts in health-related quality-of-life instrument development, has resulted in a short version of the Cerebral Palsy quality of life instrument.IMPLICATION FOR REHABILITATIONThis study provides the first classification system for children with Cerebral Palsy.The Cerebral Palsy-six dimension (CP-6D) survey, which is a short version of Cerebral Palsy Quality Of Life instrument, can be timesaving when measuring quality of life in children with Cerebral Palsy.The short version (CP-6D) can be used in preference based measurement and generate quality adjusted life years for children with Cerebral Palsy.

Abstract: In recent years, discrete choice experiments (DCEs) have become frequently used to generate utility values, but there are a erse range of approaches to do this. The primary focus of this systematic review is to summarise the methods used for the design and analysis of DCEs when estimating utility values in both generic and condition-specific preference-based measures. Published literature using DCEs to estimate utility values from preference-based instruments were identified from MEDLINE, Embase, Cochrane Library and CINAHL using PRISMA guidelines. To assess the different DCE methods, standardised information was extracted from the articles including the DCE design method, the number of choice sets, the number of DCE pairs per person, randomisation of questions, analysis method, logical consistency tests and techniques for anchoring utilities. The CREATE checklist was used to assess the quality of the studies. A total of 38 studies with s les from the general population, students and patients were included. Values for health states described using generic multi attribute instruments (MAUIs) (especially the EQ-5D) were the most commonly explored using DCEs. The studies showed considerable methodology and design ersity (number of alternatives, attributes, s le size, choice task presentation and analysis). Despite these differences, the quality of articles reporting the methods used for the DCE was generally high. DCEs are an important approach to measure utility values for both generic and condition-specific instruments. However, a gold standard method cannot yet be recommended.

Abstract: Economic-evaluations of Cerebral palsy (CP) were based on utility estimates of health-related quality of life (HRQoL) from generic multi-attribute utility instruments (MAUIs). However, generic instruments had limited use as they could not capture some of the important aspects of living with CP. The Cerebral palsy 6 Dimension (CP-6D) is a disease specific MAUI. In this study, we compared the results of CP-6D with the Assessment of Quality of Life (AQoL-4D), a generic MAUI, and tested the criterion validity of the CP-6D in the general population. An online survey of the Australian general population (n = 2002), who completed both the AQoL-4D and CP-6D MAUIs, was conducted. Validity was assessed from the correlations between the domains, items and instruments. ANOVA and t-tests were used to assess the instrument's discrimination in different social demographic categories. There was a moderate correlation between the instruments (0.64). Differences in socio-demographic characteristics showed a medium effect size ( Our results suggest that CP-6D and AQoL-4D were measuring a similar underlying construct. Both instruments responded similarly to socio-demographic differences.

Abstract: Cerebral palsy (CP) is a lifelong condition. The CP quality of life (CPQOL) instrument is a frequently used disease-specific instrument to assess health-related quality of life (HRQoL) in people with CP, but it cannot be used to generate quality-adjusted life years (QALY) which are the basis of cost utility analysis (CUA). Generic utility instruments (such as the EQ-5D or SF-6D) that are used to value HRQOL may be insensitive to small but important health changes in children with CP. This study aims to generate a preference-based scoring algorithm for the CP six dimensions (CP-6D), a classification system developed from the CPQOL. A discrete choice experiment with duration (DCEtto) will be administrated to value health states described by the CP-6D classification system. These health states will be presented to members of Australian general population and parents of children with CP via an online survey. Conditional logit regression will be used to produce the utility algorithm for CP-6D. The Griffith University Human Research Ethics Committee approved for the study (reference HREC/number 2018/913). The developed algorithm can be applied to previous and future economic evaluation of interventions and treatments targeting people with CP which have used either the CPQOL or CP-6D.

Abstract: There is evidence from previous studies that adults value paediatric health-related quality of life (HRQoL) and adult HRQoL differently. Less is known about how adolescents value paediatric HRQoL and whether their valuation and decision-making processes differ from those of adults. Discrete choice experiments (DCEs) are widely used to develop value sets for measures of HRQoL, but there is still much to understand about whether and how the methods choices in the implementation of DCE valuation tasks, such as format, presentation and perspective, affect the decision-making process of participants. This paper describes the protocol for a qualitative study that aims to explore the decision-making process of adults and adolescents when completing DCE valuation tasks. The study will also explore the impact of methodological choices in the design of DCE studies (including decisions about format and presentation) on participants’ thinking process. An interview protocol has been developed using DCE valuation tasks. Interviews will be conducted online via Zoom with both an adolescent and adult s le. In the interview, the participant will be asked to go through some DCE valuation tasks while ‘thinking aloud’. After completion of the survey, participants will then be asked some predetermined questions in relation to various aspects of the DCE tasks. Interviews will be recorded and transcribed and analysed using a thematic analysis approach. Ethics approval for this study has been received for the adult s le (UTS ETH20-9632) as well as the youth s le (UTS ETH22-6970) from the University of Technology Sydney Human Research Ethics Committee. Results from this study will inform the methods to be used in development of value sets for use in the health technology assessment of paediatric interventions and treatments. Findings from this study will also be disseminated through national/international conferences and peer-reviewed journals.

Abstract: Autosomal recessive (AR) and x-linked (XL) conditions are rare but collectively common which impact millions of people globally on morbidity, mortality and costs. Advanced medical technologies allow prospective parents to make informed reproductive decisions to avoid having affected children. Economic evaluations targeting on reproductive carrier screening (RCS) for AR and/or XL conditions have been conducted, but there has not been a systematic review in this area. A systematic search of economic evaluations for RCS was undertaken using the following databases - EMBASE, MEDLINE and SCOPUS. The search strategy was designed to capture full economic evaluations related to RCS since 1990. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) strategy. The included 23 studies adopted various types of methodologies to conduct economic evaluations. The majority of studies examined a single condition. The various clinical strategies and screened conditions caused the different cost-effectiveness conclusions in the published studies. Establishing a validated and practical clinical strategy of RCS and investigating the cost-effectiveness of multiple conditions in one economic evaluation are critical for implementing RCS in the future. Further economic evaluations are essential to provide evidence-based practice for decision-makers.
