Apostolos Davillas, Mireia Jofre-Bonet, David Mott, Chris Sampson, Bernarda Zamora, and Kyann Zhang will be attending the conference and contributing to the programme in various capacities.


OHE work to be discussed:


A latent class approach to inequity in health using biomarker data

Tuesday, 7 January, 15:30 – 16:30, Locomotion 1

Authors: Apostolos Davillas, Vincenzo Carrieri and Andrew M. Jones

Summary: An empirical approach was developed to analyse, measure and decompose Inequality of Opportunity (IOp) in health, based on a latent class model. This aims to address the limitations that affect earlier work in this area concerning the definition of types – such as partial observability, the ad hoc selection of circumstances, the curse of dimensionality and unobserved type-specific heterogeneity – that may lead to either upwardly or downwardly biased estimates of IOp. The latent class approach was applied to quantify IOp in allostatic load, a composite measure of the biomarker data. Using data from Understanding Society (UKHLS), it was found that a latent class model with three unobserved types best fits the data and that these types differ in terms of their observed circumstances. Decomposition analysis shows that about two-thirds of the total inequality in allostatic load can be attributed to the direct and indirect contribution of circumstances.

Uncertainty in patient trade-offs: issues in the reporting of marginal rates of substitution in discrete choice experiments

Wednesday, 8 January, 10:30 – 11:25, Northumbrian

Author: David Mott, Nour Chami and Tommi Tervonen

Summary: The primary objective of this paper was to review recently published discrete choice experiment (DCE) studies that elicit patient preferences in relation to the reporting of marginal rates of substitution (MRS). A further objective was to explore the accuracy of using other reported information to estimate the uncertainty of MRS when it is not reported.

Risk calculation engines, cost-effectiveness analysis, and Microsoft Excel: lessons from an intractable model

Wednesday, 8 January, 11:45 – 12:45, Rocket

Author: Chris Sampson

Summary: Decision analytic cost-effectiveness models are increasingly complex. One contemporary demonstration of this is the potential to integrate risk calculation engines, which can be used to dynamically determine parameters within a model. Microsoft Excel is one of the most commonly used software packages for the development of cost-effectiveness models, but it has recently faced criticism due to its supposed limitations. The purposes of this paper are twofold – first, to provide guidance on the incorporation of risk calculation engines into cost-effectiveness models and, second, to outline some of the practical limitations of Excel in this context

Chair: Helen Dakin. Discussant: Ed Wilson.
