ARIA is a component of FDA’s Sentinel System that is used to conduct medical product safety surveillance. ARIA consists of:
- Pre-defined, parameterized, reusable routine querying tools
- The electronic data in the Sentinel Common Data Model
This graphic displays the total number of analyses conducted by FDA in ARIA since its launch in 2016. There are several types of analyses, including:
- Summary table analyses
- Level 1 analyses
- Level 2 analyses
More technical information on these analyses are on the Routine Querying Tools section. Results from these analyses are on the Assessments page, as they become available. Key regulatory outcomes for these analyses are on Completed ARIA Assessments & Impact.

ARIA uses parameterizable tools and a trusted multi-site distributed database. The data undergoes continuous quality checks and refreshes. With ARIA, safety analyses are conducted more efficiently—in a matter of months, rather than years. It also fulfills the mandate in the FDA Amendments Act of 2007.
FDA uses ARIA to conduct several types of analyses to monitor the safety of FDA approved medical products.
Level 1: Descriptive Analyses, Unadjusted Rates
Level 1 analyses characterize patterns of use of prescription medications or calculate rates of health outcomes of interest.
Levels 2 and 3: Adjusted Analyses with Sophisticated Confounding Control
Level 2 and 3 analyses are used to study whether an adverse effect is potentially related to a drug. It also estimates the size of that risk, if one is identified. Lastly, ARIA can also be used to detect new safety signals.
FDA uses ARIA to study signals that come from many sources, such as the FDA Adverse Event Reporting System (FAERS), observational studies, or clinical trials. To learn more, please refer to FDA’s Best Practices for Postmarket Safety Surveillance document.
With ARIA, safety analyses happens more efficiently. It also fulfills the mandate in the FDA Amendments Act of 2007.
