FHIR-native
Built around source records, not screenshots or pasted summaries.
Lattice Health
Clinical memory for fragmented care.
Lattice helps clinicians reconcile outside records into a provenance-preserved patient memory, with explicit human adjudication before anything becomes truth.
ED reconciliation
Longitudinal memory
2 high-risk conflicts
Candidate
Keep diabetes on active problem list
Current
Inactive in PCP chart
Proposed
Active, supported by meds and A1c
Source trail: Epic sandbox condition, pharmacy fill, outside observation
Accept
Defer
Reject
Platform
Records are not truth until someone reconciles them.
Clinician-gated
Conflicts stay pending until a human explicitly adjudicates them.
Provenance first
Every accepted memory can point back to where it came from.
Workflow
Built for the clinical gray zone.
Lattice is designed around the part of medicine where the chart is noisy, the patient is moving, and deleting uncertainty would be unsafe.
- 1Ingest outside records from connected systems
- 2Cluster duplicate and conflicting clinical facts
- 3Surface reconciliation candidates by risk tier
- 4Write back only clinician-approved updates
Pilots
Starting with emergency medicine, expanding wherever fragmented records create risk.
Built by an emergency physician and medical educator in the Bronx.
The product bias is practical: help clinicians reason with messy records under time pressure, without pretending uncertainty disappeared.
Emergency departments
Give clinicians a fast, defensible longitudinal view when the patient is new, unstable, or unable to narrate their history.
Health systems
Turn interoperability feeds into an auditable reconciliation workflow instead of another pile of untrusted outside data.
Clinical educators
Teach learners how to reason with messy records, conflicting sources, and uncertainty without erasing provenance.
Building with clinical reality in mind.
Lattice is early, synthetic-data friendly, and looking for thoughtful pilot conversations with teams who feel the pain of reconciliation every day.
