The newly-launched MyHealthDecision website offers a set of easy to use on-line decision support tools to help people make decisions about their health. Our goal is to empower individuals to make the best health choices for themselves, either in a shared process with a health professional or as an independent person.

Two key concepts underpin our approach to the web site. The first is that the decision support is based on the multi-criteria decision analytic (MCDA) framework, which is able to capture and represent the attributes (criteria) important to the individual in a transparent way and combine them with the best available evidence, again in a clear and open way. This leads to the second key concept – empowerment through a person-centred philosophy. The decision tools personalise by eliciting each individual's importance weights for the attributes, synthesising these with the best personalised estimates available now for the performance of the options on those attributes. A flexible online system for producing and delivering decision support tools has been developed in the weighted-sum implementation of MCDA called Annalisa©, which is embedded in the Elicia© survey program to enable individual customisation as well as evidence personalisation. The single-screen graphic output from a tool developed in this system presents ratings and rankings for all the options, providing an 'opinion' that synthesises the performance ratings for each option on each criterion with the criterion importance weights expressed by the user.

In this presentation we will focus on the core product of the web site, the on-line decision tool; on our capacity to tailor the support to individuals; on the capacity of the site to engage communities of professionals in debate about, and updating of, the multi-criteria evidence matrix for specific decisions; and the capabilities of the site to analyse the user experience.
