• Useful Decision Support tools do not make decisions –
  they help people make decisions
• Specifically, they assist with four key functions:
   1.   Identifying/assembling promising alternative courses of action
        (e.g., treatment protocols) germane to patients’ and/or
        physicians’ specific situation and needs

   2.   Determining detailed case-specific requirements and
        implications of competing alternatives

   3.   Assessing relative tradeoffs (e.g., costs, benefits, risks...) of
        alternatives from personalized perspectives

   4.   Formulating personalized metrics and triggers for future
        “continue vs. revise” decisions regarding adopted choices
