The primary objective is to provide an introduction to formal elicitation methods to support a range of HCDM processes, across a range of settings. This emerging good practice guidance will fill a gap in guidance on the use of expert elicitation in a wide range of decision and modelling contexts.
The evidence used to establish cost-effectiveness and inform healthcare decision making (HCDM) is typically uncertain. With a less developed (and often a limited) evidence-base, judgments based on consultation with individuals who have expertise on the subject matter, can be vital. However, in the absence of definitive evidence, experts are likely to be uncertain about their beliefs. A process to capture their beliefs should reflect this. To improve accountability and consistency within HCDM processes, it is desirable that these judgments are made explicit, using a formal and structured process. There is a lack of both clear guidance and empirical studies comparing methods.
