This session addresses the concern of inconsistent real world evidence in drug safety by presenting 1) epidemiological approaches for assessing inconsistent findings in observational studies, 2) lessons learned from observational studies in a distributed research network and 3) challenges using methods that synthesize findings from observational studies. Learning Objectives Identify possible study factors contributing to heterogeneity of real world evidence using claims databases; Discuss lessons learned from observational studies in a distributed research network regarding heterogeneity of RWE; Describe methods for synthesizing findings from observational studies and their limitations.
