MediMesh: Collaborative Patient Insight Network

Core Functionality

• Mesh‑Based Data Sync: Peer‑to‑peer encrypted sharing of EHR snippets, imaging metadata, and vitals without central servers, ensuring continuity during connectivity outages.
• Collaborative Annotation Layer: Real‑time markup on PDFs, DICOM images, and voice notes with version control and audit trails.
• AI Insight Engine: Natural language processing extracts key clinical facts, cross‑references drug interactions, and flags abnormal trends for quick review.
• Workflow Orchestration: Customizable task boards that auto‑assign follow‑ups based on annotations and AI risk scores.
• Compliance & Audit Hub: Built‑in GDPR/HIPAA audit logs with tamper‑evident signatures and role‑based access controls.

Problem It Solves

Healthcare teams often face fragmented patient information spread across multiple EHR systems, paper notes, and disparate imaging archives. During emergencies or remote shifts, this leads to delayed decisions, duplicated tests, and increased risk of adverse events. MediMesh consolidates these silos into a secure mesh network that persists even when internet is unavailable, enabling clinicians to collaborate instantly with contextual AI support.

Technical Requirements

• Flutter for cross‑platform UI (iOS/Android).
• Libp2p / MeshSync for decentralized peer‑to‑peer networking.
• Dart + TensorFlow Lite for on‑device NLP and risk scoring.
• SQLite + FFI for local caching with encryption.
• FHIR APIs integration layer for interoperability with hospital systems.

Monetization Strategy

1. Enterprise Licensing: Tiered subscription per user or department, including dedicated support and on‑premise deployment options.
2. Marketplace Extensions: Plugin store where third parties can sell AI models or specialty annotation tools.
3. Data Insights Analytics: Aggregated, anonymized usage metrics sold to health authorities for population health studies (with strict privacy safeguards).

Implementation Approach

1. Prototype Phase (Month 1‑2): Build Flutter UI skeleton, integrate Libp2p mesh demo, and set up local encrypted SQLite storage.
2. Core Sync Engine (Month 3‑4): Implement peer discovery, message passing, conflict resolution, and audit logging.
3. Annotation Module (Month 5‑6): Add PDF/DICOM viewer with markup tools and real‑time sync of annotations across peers.
4. AI Insight Layer (Month 7‑8): Deploy TensorFlow Lite models for clinical fact extraction and risk flagging; expose via local API.
5. Compliance & Security Hardening (Month 9): Integrate HIPAA compliance modules, role‑based access, and tamper‑evident logs.
6. Beta Rollout & Feedback Loop (Month 10‑11): Release to a pilot hospital unit, collect usage data, refine UX.
7. Enterprise Launch (Month 12): Finalize licensing engine, marketplace infrastructure, and marketing materials.

Potential Challenges

• Network Reliability: Mesh performance may degrade in high‑density environments; solution: adaptive bandwidth throttling and priority queues for critical messages.
• Regulatory Compliance: Ensuring end‑to‑end encryption meets HIPAA and GDPR; solution: conduct third‑party security audits and provide audit logs to administrators.

Future Expansion

• Multilingual Support: Extend NLP models to support non‑English clinical notes.
• Remote Patient Monitoring Integration: Pull vitals from wearable devices into the mesh for real‑time alerts.
• VR/AR Collaboration: Allow clinicians to view and annotate 3D imaging in shared AR sessions.
• Blockchain Ledger: Record immutable consent and data sharing agreements for legal traceability.
