Business Outcome

Extract medical conditions, dosages, and protect patient privacy by scrubbing names, dates, and locations from unstructured doctor notes with 99.5% entity recall under deterministic human supervision.

Acceptance Criteria:

Zero leaked primary patient direct identifiers (names, SSN, TC Kimlik) in 10,000 test note audit.

Heuristic Baseline

Regex pattern matching: Comprehensive regular expressions scanning for SSN, phone numbers, Turkish TC Kimlik, and date formats.

Baseline Evaluation:

Regex alone achieved only 81% recall on names and failed on misspellings and unstructured narrative sentences.

Phase 1: Prototype Path

Evaluate en_core_web_trf / custom clinical spaCy pipeline on synthetic medical record sample. Measure precision and recall across PHI categories.

Hardware: Standard laptop or workstation with 16GB RAM

Phase 2: Production Path

Package spaCy pipeline into hardened Docker container. Deploy within hospital air-gapped on-premise Kubernetes cluster with CPU inference and strict audit logging.

Hardware: Enterprise on-premise server (8+ CPU cores, 32GB RAM, no cloud network access permitted)

Compute & Placement Topologies

Training Placement

Fine-tuned on isolated private GPU server with synthetic/de-identified training data

Inference Placement

On-premise air-gapped hospital server running CPU inference under private intranet

3-Plan Placement Alternatives

Plan A: Simplest Viable

Local Python CLI script running rule-based regex + small spaCy model on doctor desktop.

Plan B: Hardware-Fitted

Multi-core on-premise hospital application server running quantized transformer pipeline on CPU.

Plan C: Production-Ready

Air-gapped on-premise Kubernetes deployment with mutual TLS + audit trail logging + deterministic human review queue for low-confidence entity masks.

Governance, Safeguards & Risks

Governance Safeguards:
  • Safety & regulatory boundary: This system is strictly an administrative and research assistance tool for text de-identification; it MUST NOT be used as an autonomous clinical diagnostic or medical decision-making system.
  • Human-in-the-loop oversight: All entity redactions for research release must pass a deterministic human verification queue for confidence scores below 0.99.
  • Hospital data governance mandate: Strictly forbid external cloud API transmission of unmasked patient records.
  • Model supply chain: Require SafeTensors or signed ONNX model packaging to eliminate arbitrary code execution inside the hospital clinical network.
