29
An approach to research prioritization which uses Bayesian methods to estimate the potential benefits of gathering further information (through more research) before making a decision (Meyers, et al., 2012) A tool of the decision sciences, estimates the potential economic losses associated [with] choosing suboptimal policies when that decision is made with uncertain information (Rhein, 2012) A decision analytic technique that explicitly evaluates the benefit of collecting additional information to reduce or eliminate uncertainty. (Yokota and Thompson, 2004) Value of Information
30
General Challenges to the Use of VOI for Research Prioritization Resources needed to develop appropriate models Personnel Time Computing Resources Scope of VOI Prioritizing across disease areas Prioritizing within a condition Prioritizing specific comparative effectiveness research Stakeholder Engagement Lack of familiarity with the methodology Timing of VOI
31
Personnel Time Computing Resources “minimal modeling appears to be most useful when an intervention affects quality of life alone” 3 Resources Needed to Conduct VOI
32
Difference between the expected value given perfect information and the value given current information i.e. the upper bound of the opportunity cost of making a wrong decision; any effort to improve the quality of available data that costs less than the EVPI is worth pursuing Expected Value of Perfect Information (EVPI)
33
Calculating EVPI EVPI is calculated as the expected value of a decision made with perfect information minus the expected value of a decision made with the existing information: EVPI = E max j NB(j, ) - max j E NB(j, )
34
Go/no go measurement to determine if additional research is appropriate Comparison for cost effectiveness of research across different interventions Using EVPI for Research Prioritization
35
The value of being able to know the outcome of another related uncertainty instead of the original value itself before making a decision. It is quantified as the highest price the decision-maker is willing to pay for being able to know the uncertainty before making a decision. Note that it is essentially the value of perfect information on the second variable. Expected Value of Partial Perfect Information (EVPPI)
36
Using VOI by Research Sponsor, such as PCORI Perform VOI prior to solicitation for research proposals and only request areas identified as having acceptable EVPI/EVPPI Perform VOI after initial review of proposals as part of funding decisions with higher EVPI/EVPPI receiving higher priority for funding Research sponsor could encourage or require investigators to include VOI analysis as part of rationale for proposals
37
Treatment Decision Tree
38
Justify additional research in advance of adapting specific interventions Identifying which areas contribute the most to uncertainty Common uses of VOI
