Slide content:Using a Decision Analysis Elicit utility values for outcomes from patient, such as risk of adverse events from disease or treatment Calculate probabilities of events based on best evidence Fold back decision tree to calculate overall utility 14
Slide notes:14 How do we actually use a decision analysis? Essentially, we have to put numerical values on the pathways through the decision tree. Some of those pathways involve incorporating utility values that the patient has. Patients may express preferences for adverse outcomes. They may be more tolerable of stroke or of bleeding. Sometimes in the cases of surgery patients, they may be more willing to tolerate the up-front risks of surgery than to risk the consequence of not having surgery and possibly having a longer-term worse outcome. So we plug evidence values and utility values into the tree, then we do a process called folding the tree back , where we basically determine the optimal pathway through the tree.
