Engineering a HIPAA-gated Ambient AI Mesh to capture clinical intent in real-time, reducing 'pajama time' documentation by 65% while maintaining 100% EHR schema integrity.
Trusted by Leading Fortune 500 Innovators
High-volume clinical environment across Oncology, Cardiology, and Primary Care requiring specialized charting.
AI Architect + Clinical Data Engineer + HIPAA Compliance Lead embedded within Hospital IT.
Automating clinical documentation to restore provider-patient face time and eliminate evening charting backlogs.
Diarized audio streams, FHIR-integrated RAG, and fine-tuned med-large language models (LLMs).
The client’s providers were trapped in a 'Documentation Debt' cycle, spending 2 hours on EHR entry for every 1 hour of patient care. This administrative friction resulted in 30% of charts being completed at home—the 'Pajama Time' effect—leading to clinical fatigue and data entry errors.
The risk was systemic: provider turnover was increasing, and patient throughput was capped by typing speed rather than clinical capacity. The hospital required a 'Zero-Persistence' AI scribe that could diarize multi-person encounters without violating strict HIPAA PHI-trapping rules.
Typing notes during or after the visit, distracting from the patient encounter.
AI listens in the background; clinical intent is mapped to EHR fields automatically.
Physical scribes or audio recordings stored on unmanaged devices/servers.
Compute occurs in volatile memory; PHI is never persisted outside the hospital's EHR.
Wait times for scribe services meant notes weren't billable for a full day.
Notes are ready for signature the moment the provider exits the exam room.
The AI distinguishes between 'small talk' and 'clinical directives,' only populating medically relevant data into the FHIR-standard fields.
Hardened VPC boundaries ensure audio data streams are isolated from the public internet and local storage backends.
Real-time PII/PHI scrubbing for all training logs to ensure model refinements never compromise patient anonymity.
Pre-audited zero-persistence streaming templates for medical-grade audio ingestion.
Translation logic to map unstructured natural language into standard EHR resource schemas.
Real-time monitoring for transcription accuracy and provider sign-off velocity.
Automated model right-sizing (switching between large and small models) to maintain ROI.
Automated scribing removed the evening charting burden, returning personal time to providers.
Faster documentation allowed providers to see additional patients without extending work hours.
Internal surveys showed a massive shift in morale once 'Pajama Time' documentation was eliminated.
Client Testimonial
Coretus didn't just give us a tool; they restored the provider-patient relationship. By eliminating the 'Pajama Time' documenting hours, our specialists are actually practicing medicine again instead of acting as data entry clerks.
