The news • Applying analytics and risk- management capabilities to health insurance through LexisNexis data platforms. • Databases on 250 million people in the U.S. sampled from 35 billion public records. • Data analysis using its supercomputer platform, which is built on top of open-source platform (High Performance Computing Cluster) • Allows for fast queries of "massive amounts of big data.”
LexisNexis HealthCare Solution • Earlier Situation: Pay and Chase model - insufficient and unsustainable • Current Solution: • Proactive - identifies and mitigates fraud throughout business workflow • Identify fraud patterns and risk indicators as they emerge.
Predictive Modeling Metrics Scores Detect inherent risks Traditional Method: Single claim Claim Edit No pattern identification
Predictive Analysis Definition: Predictive Analysis translates data into descriptive or predictive models using various forms of statistical analysis techniques • Classification and Regression Trees (CART) Chi Square Automatic Interaction Detection (CHAID) . • Linear and logistic regression models • Analysis of variance • Discriminate analysis.
Benefits • Early detection of fraud, waste and abuse • Prioritized results with fewer false positives • Alerts concerning adverse changes in the status of individuals or entities • Consistent control over risk, quality and costs using automated screening and monitoring • Lower claims losses, better financial management than traditional “post-payment only” methods
IBM SPSS Modeler • Understand your data – Patient demographics, Hospital Information etc. • Determine your population makeup – Sampling issues, representativeness • Discover relationships in your data – Relations between various variables identified in Step 1 • Build a model – Rule induction and based on step 3 • Use model against actual records – Test for predictive power • Identify anomalies – Outliers
Other Vendors • SAS datamining tool – tree based model , multianalytics approach • IBM SPSS modeler – rule induction
