BACKGROUND Conventionally, parametric models were used for health state valuation data. Recently, researchers started to explore the use of nonparametric Bayesian methods in this area. OBJECTIVES We present a nonparametric Bayesian model to estimate a preference-based index for two condition-specific five-dimensional health state classifications, one for asthma (five-dimensional Asthma Qualit...

OBJECTIVE Cost-utility analyses use information on health utilities to compare medical treatments that have different clinical outcomes and impacts on survival. The purpose of this study was to describe the health utilities associated with diabetes and its treatments, complications, and comorbidities. RESEARCH DESIGN AND METHODS We studied 2,048 subjects with type 1 and type 2 diabetes recrui...

This Appendix provides the basic derivations of the multi-country trade model of heterogeneous firms presented in Hesse (2014). The ensuing presentation borrows from Dixit & Stiglitz (1977), Melitz (2003) as well as Helpman et al. (2010a) and its technical appendix, Helpman et al. (2010b). The preferences of a representative consumer are given by a C.E.S. utility function over a continuum of va...

BACKGROUND The Malay spoken in Brunei a South East Asian country where Malay is the national language is distinctive and different from Malay spoken in Malaysia, Singapore and Indonesia. This study aimed to develop a Brunei Malay version of the 5-level EQ-5D questionnaire (EQ-5D-5L) and to assess its psychometric properties among patients with type 2 diabetes mellitus (T2DM). METHODS The Brun...

OBJECTIVE To analyse and report the costs and effects of etanercept therapy in patients with JIA. METHODS Forty-nine JIA patients were evaluated by means of the JIA core set at the start of etanercept and after 3, 15 and 27 months of therapy. At the same time-points, parents of the patients were asked to complete the Health Utility Index Mark 3 (HUI3). Direct medical costs were collected for ...

BACKGROUND The SF-6D is a new health state classification and utility scoring system based on 6 dimensions ('6D') of the Short Form 36, and permits a "bridging" transformation between SF-36 responses and utilities. The Health Utilities Index, mark 3 (HUI3) is a valid and reliable multi-attribute health utility scale that is widely used. We assessed within-subject agreement between SF-6D utiliti...

OBJECTIVE The Panel on Cost-Effectiveness in Health and Medicine recommended the compilation of a catalog of health state utility weights for use in cost-utility analyses (CUAs), and has given methodological recommendations. This study presents an update, through 2001, to our current registry of utility weights (available at http://www.tufts-nemc.org/cearegistry; previously at http://www.hsph.h...
