The Spanish five-level EuroQol five-dimensional questionnaire (EQ-5D-5L) valuation study was the first to use Valuation Technology protocol, including composite time trade-off (C-TTO) and discrete choice experiments (DCE). In this study, its investigators noticed that some interviewers did not fully explain C-TTO task respondents. Evidence from a follow-up in 2014 confirmed when followed distribution of responses widened.To handle data quality issues by estimating hybrid interval regression...

Treatment of hyperglycemia in women with gestational diabetes mellitus (GDM) is associated improved maternal and neonatal outcomes requires intensive clinical input. This currently achieved by hospital clinic attendance every 2 to 4 weeks limited opportunity for intervention between these visits.We conducted a randomized controlled trial determine whether the use mobile phone-based real-time blood glucose management system manage GDM remotely was as effective controlling standard care...

Electronic health records are invaluable for pregnancy-related studies. The Clinical Practice Research Datalink (CPRD) Pregnancy Register (PR) identifies pregnancies in primary care records, including uncertain cases. This paper outlines a method to reduce uncertainty identifying within CPRD GOLD PR data, exemplified through study investigating the provision of pre-pregnancy care. We used Mother Baby Link (MBL) and Maternity Hospital Episode Statistics (HES) clean augment data. included all...

Background. Reliably mapping from generic or diseasespecific health status measures into state utilities would assist economists. Existing studies mainly use ordinary least squares (OLS) regression equations to predict utility values for particular states. The authors examine an alternative approach tomap between 2 instruments, the SF-12 and EQ-5D. Methods. Multinomial logit is used estimate probability that a respondent will select level of response questions in EQ-5D, using individual...

Background. Mapping disease-specific instruments into generic health outcomes or utility values is an expanding field of interest in economics. This article constructs algorithm to translate the modified Rankin scale (mRS) EQ-5D values. Methods. mRS and information was derived from stroke transient ischemic attack (TIA) patients identified as part Oxford Vascular study (OXVASC). Ordinary least squares (OLS) regression used predict UK tariffs scores. An alternative method, using multinomial...

The EQ-5D instrument is the most widely used preference-based health-related quality of life questionnaire in cost-effectiveness analysis health care technologies. Recently, a version called EQ-5D-5L with 5 levels on each dimension was developed. This manuscript explores performance hybrid approach for modeling valuation data.Two elicitation techniques, composite time trade-off, and discrete choice experiments, were applied to sample Spanish population (n=1000) using computer-based...

In health preference research (HPR) studies, data are generated by participants'/subjects' decisions. When developing an HPR study, it is therefore important to have a clear understanding of the components decision and how those stimulate participant behavior. To obtain valid reliable results, study designers must sufficiently describe model its components. studies require detailed examination criteria, documentation descriptive framework, specification hypotheses. The objects that subjects'...
