Problem
Healthcare organizations struggle to obtain complete, up-to-date patient records across fragmented electronic health record systems, leading to delayed care decisions, inefficient workflows, and higher costs.
Solution
Particle Health provides a nationwide interoperability platform that aggregates, cleans, and enriches clinical data from over 70,000 health organizations, including HIEs, ADT feeds, and pharmacy sources. Its Record Locator Service identifies patients by geography, known conditions, medication history, and recent activity, then matches them to a universal identifier to ensure accurate record linkage. The platform delivers near‑real‑time, de‑duplicated data in standardized FHIR R4 or C‑CDA formats via a single RESTful API, enabling developers and health systems to embed actionable insights directly into EHRs, care management tools, and value‑based care workflows. Security and compliance are built in, with HIPAA, SOC 2, and HITRUST certifications and detailed data provenance.
