    • 1. www.edgewater.com October 1, 2008 Predictive Analytics in Healthcare
    • 2. <ul><li>Introduction </li></ul><ul><ul><li>Approaches & Methods </li></ul></ul><ul><li>Supporting the Healthcare Value Chain </li></ul><ul><ul><li>Translational Research </li></ul></ul><ul><ul><li>Hospital Operations </li></ul></ul><ul><ul><li>Risk Management </li></ul></ul><ul><li>Implementation </li></ul><ul><ul><li>System & Data Architecture </li></ul></ul><ul><ul><li>Process Framework for Development & Deployment </li></ul></ul>Predictive Analytics: Overview
    • 3. Predictive Analytics: Various Approaches CLUSTERING FORECASTING MONITORING & ADVISING SIMULATION & SCENARIO PLANNING DECISION TREE  The use of current and past data, in conjunction with statistical, structural or other analytical models and methods, to determine the likelihood of certain future events Predictive methods cover the spectrum from relatively simple classification and forecasting to more advanced techniques such as simulation and advising As you move up the spectrum, the complexity of the approaches and their implementation increase
    • 4. Clustering as Classification <ul><li>Hierarchical clustering of 107 genes selected from 12,000 </li></ul><ul><li>Progressive expression relative to normal: </li></ul><ul><ul><li>Increase: Red </li></ul></ul><ul><ul><li>Decrease: Green </li></ul></ul>Yeatman, et al: JNCI, April 2002 Osteopontin
    • 5. Class Discovery and Class Prediction Golub, et al: SCIENCE, October 1999 <ul><li>Diagnostic classification based on molecular characteristics of disease, i.e. differentially expressed genes </li></ul><ul><li>Automatically discovered the distinction between acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) </li></ul><ul><li>Establishes disease classes, and then uses those class definitions to determine the correct classification for new undiagnosed cases </li></ul><ul><li>Also succeeded in discovering these classes independent of previous biological knowledge </li></ul><ul><li>Enables More Effective, Less Toxic </li></ul><ul><li>Treatment </li></ul>
    • 6. Class Distinction, Combined with Pathway Model Wei, et al: Cancer Cell, October 2006 GC apoptosis (cell death) rapamycin MCL1
    • 7. Decision Tree: Progressive Class Distinction <ul><li>340 new tumor markers </li></ul><ul><li>100 tumor progression markers whose expression correlated with progressing tumor stage </li></ul><ul><li>Descend tree using any available differentiating attributes; natural, derived or inferred; separately or in combination </li></ul>
    • 8. Forecasting: Process Model  Structural Model: Bill of Resources Patient Seen in Emergency Dept Admit Patient: Presumptive Diagnosis: Pneumonia Discharge Monitor Care Delivery Standard Order Sets Equipment Labor Materials Facilities Nursing Orders: Respiratory Therapy: Medication Orders: Resource Demand Day 5 Day 4 Day 3 Day 2 Day 1    
    • 9. Forecasting: Resource Demand vs. Capacity Standard Order Sets Equipment Labor Materials Facilities Nursing Orders: Respiratory Therapy: Medication Orders: Day 5 Day 4 Day 3 Day 2 Day 1    
    • 10. Simulation: Resource Demand vs. Capacity  What if … … incidence of disease X increases 2x? … process X increases throughput 1.5x? … market share in geography X (with Y / 1000 cases) increases by Z? … we focus our service lines into centers of excellence, shifting our patient mix across our facilities within the system? Facility A Facility B Facility C
    • 11. Monitoring & Advising: Risk Management Patient & Case Profiled Against Risk Model Incrementally Accumulate Evidence of Emerging Risk Retain Case Instance & Feedback to Risk Model Notify Risk Mgmt Team of Need for Corrective Action Monitor Care Delivery Isolate Root Causes Track Negative Outcomes Track Key Events Within a Process Track Incidents <ul><li>Track outcomes </li></ul><ul><li>Identify variances from standard of care </li></ul><ul><li>Isolate root causes in case characteristics or provider actions </li></ul><ul><li>Identify case as high cost, high risk; discern patterns using attributes of case or care </li></ul><ul><li>Show evidence that case is aligning with risk pattern; notify parties to intervene, or avoid </li></ul><ul><li>Similar approach for protocol compliance; wellness & outreach; “activated/able” patients </li></ul>Forecast Non- Reimbursement Loss Tie to Claims Data Tie to Clinical Data Track Litigation Improve Quality, Avoid Future Incidents
