Discovery & Research for Healthcare

Discovery and Research workflows ask the system to find the right documents and synthesize what they say, with the citations being more important than the synthesis. Citorum's hybrid retrieval pipeline combines dense vector similarity over the embeddings of every document chunk, full-text search via Postgres' built-in indexing, and metadata filtering against tags, dates, jurisdictions, document types, and access-control attributes. Results are scored, deduplicated, and rank-fused into a context window.

The model produces a research summary; the audit log captures every document that contributed, every citation rendered, and the faithfulness score on every claim. The reviewing analyst — paralegal, compliance officer, claims coder, briefer — clicks through to source spans rather than relying on the summary verbatim. The pattern works because the citations are first-class output, not a footnote.

Healthcare deployments operate under the Health Insurance Portability and Accountability Act (HIPAA), state health-data laws, and — for federal customers — the Federal Risk and Authorization Management Program (FedRAMP) trajectory. Citorum runs inside the customer's environment so Protected Health Information (PHI) never transits a third-party model Application Programming Interface. The deployment supports the controls expected of a Business Associate: per-tenant isolation, encryption at rest with keys held in the customer's Key Management Service, audit lineage for every retrieval and response, and access controls that gate documents by patient relationship, care team, and role.

Common workflows include clinical reference research over institutional knowledge bases and society guidelines, claims-coding research over payer policies, internal Health Insurance Portability and Accountability Act (HIPAA) compliance Q&A across organizational policies, and clinical summary drafting from chart documents — each with citations and faithfulness labels so a reviewing clinician sees the system's confidence at the moment the answer is given.
