HIPAA-Compliant Patient Summaries
Automate clinical documentation by locally scrubbing Patient Health Information (PHI) before leveraging powerful external LLMs, ensuring strict HIPAA compliance and zero data leakage.
The Baseline
Doctors spend hours writing patient summaries but cannot use standard ChatGPT due to HIPAA restrictions. Exposing PHI to public AI models violates federal law, breaches patient trust, and carries massive financial penalties.
Privacy Shield acts as a local proxy, scrubbing all Patient Health Information (PHI) before routing the clinical notes to an external LLM, then re-attaching the identities locally upon return.
Automates clinical documentation while guaranteeing 100% HIPAA compliance. Physicians reclaim hours of administrative time daily, and hospital IT maintains total data sovereignty and regulatory control.
Architecture Flow
Data Ingestion (Internal)
A physician completes a consultation and dictates or types raw clinical notes into the hospital's Electronic Health Record (EHR) system. The EHR securely pushes this raw text to the AVELIN API.
Local Scrubbing (Privacy Shield)
Before the data leaves the hospital's firewall, AVELIN's Privacy Shield intercepts the payload. Local edge models detect and strip all PHI (patient names, dates of birth, addresses, Medical Record Numbers) and replace them with secure, randomized tokens.
External Inference (Model Engine)
The completely anonymized clinical text is routed to a premium external LLM (e.g., OpenAI or Claude). The model processes the medical narrative, extracts diagnostic context, and generates a structured clinical summary.
Local Re-Assembly
The AVELIN platform receives the anonymized summary from the external provider, securely maps the tokens back to the original PHI locally, and pushes the final, fully identified summary directly back into the patient's EHR file.
Core Infrastructure
| Component | Role |
|---|---|
| Privacy Shield | Executes localized Named Entity Recognition (NER) to detect, redact, and tokenize highly sensitive PHI at the edge before any internet transmission occurs. |
| Model Engine | Manages the API routing to external LLMs. Allows hospital IT to instantly swap between providers (e.g., OpenAI to Anthropic) based on performance or changing compliance rules. |
| Orchestration Engine | Manages the seamless bidirectional data flow between the hospital's legacy EHR system, the local scrubbing proxy, and the external AI models. |
