Snow Owl’s synthetic patient records are created from OSIM2, specifically designed to construct simulated datasets to supplement methods evaluation for identifying drug-outcome associations in observational data sources. The simulated datasets used in Snow Owl are modeled after real observational data sources, but are comprised of hypothetical persons with simulated drug exposures and health outcomes occurrences. Hypothetical persons are created with drug exposure periods and instances of conditions based on random sampling from probability distributions and transitional probabilities that define the relationships between the actual conditions and drugs. The relationships created within the simulated datasets mirror automatically analyzed relationships from a real observational data source. Please see
this video overview
for additional details about OSIM2.
