Bureau483 pulls inspection classification data from FDA's public Data Dashboard API. Every OAI-classified inspection is cross-referenced against issued warning letters using the facility's FEI number as the join key.
The elapsed window between inspection close date and warning letter issuance is calculated per facility. Bureau483's own historical analysis of 856 facilities from 2022–2024 found a 21.4% subsequent Warning Letter rate and a 179-day median lag — independently consistent with the only prior industry estimate ever disclosed.
Each prospect is prioritized using days elapsed, product type, and citation history — Bureau483's own analysis found facilities with prior enforcement citations convert to Warning Letters at roughly double the rate of facilities without (statistically significant, p=0.007). CFR citations from the inspection are mapped to consulting service lines, and similar historical cases are surfaced for comparison. The result is a ranked list of facilities prioritized using validated historical signals and current regulatory evidence — updated every 6 hours.
