Abstractive Health queries national Health Information Exchanges (such as Carequality) to locate a patient’s historical medical records based on geospatial data, pulling in structured data, CCDAs, and scanned PDFs. It then uses large language models to parse these disparate files into a unified, one-page longitudinal summary. When a clinician reviews the summary, each generated sentence includes a direct link back to the original source document, allowing for immediate verification of clinical claims.

Pieces Technologies is an enterprise-grade AI platform that synthesizes fragmented EHR data into concise clinical summaries.

Its Ambulatory Platform now generates "Lifetime Ambulatory Summaries," giving outpatient doctors a longitudinal view of a patient's complex history in seconds.

Navina uses AI to transform unstructured patient data into concise, clinically relevant summaries to support physicians before encounters.
