The story
A healthcare technology provider serving hospital systems that generate mountains of unstructured documentation and process over 22,000 surgical cases annually.
Trained abstractors spent an average of one hour per routine case and up to six hours for complex cases manually hunting for details in inconsistent records. This manual workflow required over 11,000 hours of labor per year for a single health system, creating a bottleneck for clinical registries.
The platform employs a two-phase pipeline where Claude extracts information from unstructured notes and synthesizes answers with direct citations. The system scores evidence for human validation, transforming clinicians from data hunters into validators who verify specific findings rather than search. A feedback loop enables experts to adjust natural language prompts and test improvements in production immediately.
Quotes
“Hospital information systems are very complex and traditional data extraction and integration workflows inside hospitals are notoriously brittle, vary widely from system to system, and often break when electronic medical records are upgraded. We needed an approach that insulated us from these inconsistencies and allowed us to deliver value without being tied to fragile, site-specific processes.”
