Description: Advanced Temporal Language Aided Search (ATLAS) is an open source software for researchers to conduct scientific analyses on standardized observational data converted to the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) Version 5 (V5). Researchers can create cohorts by defining groups of people based on an exposure to a drug or diagnosis of a particular condition using healthcare claims data. ATLAS has vocabulary searching of medical concepts to identify people with specific conditions and drug exposures. Patient profiles can be viewed within a specific cohort allowing visualization of a particular subject`s healthcare records. Population effect level estimation analyses allows for comparison of two different cohorts and leverages R packages.

ATLAS provides the ability to search and explore data source profiles, standardized vocabulary, and individual patient profiles in a database. This technology allows users to store patient-level observational health data and convert their data to Observational Health Data Sciences and Informatics` (OHDSI) open community data standards (including the OMOP CDM). Statistical data such as cohorts can be saved to the ATLAS/OMOP CDM database.

This technology can utilize databases. Data can be stored locally on either a server or a user workstation.
Technology/Standard Usage Requirements: Users must ensure their use of this technology/standard is consistent with VA policies and standards, including, but not limited to, VA Handbooks 6102 and 6500; VA Directives 6004, 6513, and 6517; and National Institute of Standards and Technology (NIST) standards, including Federal Information Processing Standards (FIPS). Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
Section 508 Information: This technology has not been assessed by the Section 508 Office. The Implementer of this technology has the responsibility to ensure the version deployed is 508-compliant. Section 508 compliance may be reviewed by the Section 508 Office and appropriate remedial action required if necessary. For additional information or assistance regarding Section 508, please contact the Section 508 Office at Section508@va.gov.
