We can make predictions and discover patterns, but what do you do with them?
Building a Pipeline Data Patterns Predictions Temporal Models Decisions
Patterns Step 3 Step 2 Step 1 Predictions Make Predictions Make Decisions Transition Models Clinical Indicators Socio-demographic a = Action/Treatment s = Patient State o = Observation c = Costs t = Time cpuc = Utility Patterns Genetic Data Etc. Markov Decision Processes (MDPs) Machine Learning/Statistical Techniques – predict risk stratification, treatment response , survival, re-hospitalization, LOS, etc. Dynamic Decision Networks (DDNs)
Step 3 Make Decisions a = Action/Treatment s = Patient State o = Observation c = Costs t = Time cpuc = Utility Belief States Plan over Time Plan/re-plan
