24 Initial Research Objectives Define and test a pool of analytical methods that can be used to explore the relationships between drugs and health-related conditions across multiple types of observational data (administrative claims, inpatient and outpatient EHRs). Develop and test methods to apply to a network of central and distributed data sources for drug safety and effectiveness questions Assess the performance of the analytical methods Based on the results of these analyses, determine how the results can shape the implementation of an active drug surveillance program. 2/20/12 Scarnecchia - OMOP 24

27 OMOP Initial Summary A risk identification system can complement current practice by providing evidence to support a comprehensive safety assessment No one clear best method, as it depends on tolerance for false positives vs. false negatives In this experiment, active surveillance methods achieved: At 50% sensitivity, false positive rate ranges 16%-30% At 10% false positive rate, sensitivity ranges 9%-33% Need to be cautious in interpreting results from single method in single database Replication does not necessarily provide complete confidence Further empirical research needed to have more complete understanding of operating characteristics before widespread adoption (Current year 3) 2/20/12 Scarnecchia - OMOP 27

28 Ongoing Research Priorities: Advance methodological research to explore the performance of methods over time, within specific populations of interest, and across a broader array of medical products and health outcomes Refine and enhance OMOP s tools and capabilities to translate research into practice Sustain the shared resource (research lab) so the research community maintains an open forum for collaborative research Develop approaches to incorporating benefits including increased application of clinical data to help ascertain benefits Additional research with these methods moves us from risk identification to risk refinement with same empiricism 2/20/12 Scarnecchia - OMOP 28
