MedScribe Clinical AI
Project Overview
MedScribe Clinical AI is a HIPAA-compliant ambient clinical documentation and structured EHR write-back platform engineered by Eternitech for a multi-specialty US outpatient healthcare group spanning 140+ attending physicians and nurse practitioners.
The Architectural Challenge
Clinicians were spending over two hours every evening completing SOAP notes and ICD-10/CPT coding in legacy EHR portals. Off-the-shelf consumer AI transcription tools failed compliance review due to third-party prompt logging, hallucinated medication dosages, and the inability to write structured clinical resources back into Epic and Cerner sandboxes via HL7 FHIR R4.
Engineering Solution & Tech Stack
An Eternitech Miami operator and senior healthcare engineering pod designed a BAA-backed, zero-PHI-retention clinical pipeline deployed inside an isolated AWS HIPAA enclave with end-to-end KMS envelope encryption.
- Streaming Medical ASR & Diarization: WebRTC audio streams into VPC-hosted Whisper-large medical endpoints with real-time speaker diarization separating clinician, patient, and caregiver dialogue.
- Evidence-Linked SOAP & Coding Engine: Multi-step LLM extraction constrained by JSON Schema links every generated assessment, medication dosage, and ICD-10-CM / CPT suggestion directly to verbatim transcript timestamps.
- HL7 FHIR R4 Bi-Directional Sync: SMART-on-FHIR OAuth2 launch context pulls active problem lists and allergies prior to the encounter and writes clinician-approved
DocumentReferenceandEncounterresources back in one click. - Automated Clinical Eval Harness: 600+ de-identified specialty gold-standard encounters run in CI on every prompt or model update to enforce zero fabricated clinical entities.
Quantified Production Outcomes
| Metric | Baseline Manual EHR | MedScribe Production |
|---|---|---|
| Average Per-Encounter Charting Time | 11.4 minutes | 4.3 minutes (-62%) |
| Same-Day Chart Closure Rate | 54% | 96.4% |
| PHI Retained in External LLM Logs | Blocked by compliance | 0 bytes (Zero-Retention BAA) |
