Key Differences Between Jeopardy and Healthcare

08/10/11

Jeopardy Healthcare

Single, known correct answer Multiple possible answers, “best” may be debatable

No substantiating evidence allowed Substantiating evidence essential

Single dimensional input from one source Multi-dimensional input from multiple sources

No dialogue/interaction by/with system Interaction by/with system – “prompting” for information

Fixed repository Dynamic repository

Evidence profile and underlying algorithms based on trivia questions

Evidence profile and underlying algorithms based on medical questions

Consequence: Significant development required

Administrative Simplification

PhysicianPatient

Physician records symptoms, medical history, and vitals

Physician determines patient is at risk for breast malignancy and wants a breast MRI. Staff requests MRI pre-authorization from WellPoint Utilization Management (UM)

UM RN reads the pre-auth request (fax/email/transcribed vm) and creates a summary. RN queries Watson and reviews Watson’s recommendation
