NIST AI RMF 1.0 Compliance Architecture

IHEP is built on the NIST AI Risk Management Framework (AI RMF 1.0), a voluntary consensus standard for managing AI risks across governance, mapping, measurement, and management dimensions. This framework, combined with Zero Trust security (NIST SP 800-207), positions IHEP as the most secure and compliant HIV care AI platform available.

NIST AI RMF 1.0: Four Core Functions

1. GOVERN

Definition: Establish AI governance structure, policies, and oversight mechanisms

IHEP Implementation:

  • AI Governance Board with clinical, technical, and ethics representatives
  • Documented AI risk appetite statement approved by executive leadership
  • Quarterly AI risk assessment reviews with board reporting
  • Clear accountability: Chief Medical Officer owns clinical safety, CTO owns technical security
  • Whistleblower policy for AI misuse or bias concerns

2. MAP

Definition: Context identification, impact analysis, and risk categorization

IHEP Implementation:

  • Context: High-stakes medical decision support for HIV care (life-threatening if system fails)
  • Impact Analysis: False negative (missing viral rebound) = patient harm; false positive = unnecessary treatment intensification
  • Risk Categories: Clinical safety (highest), data privacy (high), algorithmic bias (high)
  • Sociotechnical impact mapping: How does AI affect clinician-patient relationship? Community trust?

3. MEASURE

Definition: Track AI performance metrics, bias, and safety indicators

IHEP Implementation:

  • Performance: AUC-ROC ≥0.90 for viral rebound prediction, calibrated probability scores
  • Bias Detection: Monthly fairness audits across race, gender, age, socioeconomic status (ensure no >5% performance gap)
  • Safety Monitoring: Real-time anomaly detection for model drift, automatic rollback if accuracy drops >10%
  • Explainability: SHAP values for all predictions, clinician override rate tracked (target <5%)

4. MANAGE

Definition: Incident response, continuous improvement, documentation

IHEP Implementation:

  • Incident Response: 24/7 on-call rotation for critical AI failures, <1 hour escalation SLA
  • Root Cause Analysis: Post-incident review with corrective action plan (CAP) for all safety events
  • Continuous Improvement: Quarterly model retraining with expanded datasets, A/B testing of algorithm updates
  • Documentation: Full audit trail in compliance with FDA 21 CFR Part 11 (electronic records/signatures)

Comprehensive NIST Standards Alignment

NIST SP 800-53r5: Security & Privacy Controls

We implement a subset of the 1,000+ controls from NIST SP 800-53 Revision 5, focusing on high-impact controls for healthcare AI:

AC (Access Control): Role-based access control (RBAC), least privilege principle, MFA for all users
AU (Audit & Accountability): Comprehensive logging of all data access, immutable audit trails, 7-year retention
SC (System & Communications Protection): TLS 1.3 encryption in transit, AES-256 at rest, network segmentation
SI (System & Information Integrity): Input validation, flaw remediation, malware protection, intrusion detection
IR (Incident Response): Documented IR plan, annual tabletop exercises, breach notification procedures
RA (Risk Assessment): Annual risk assessments, vulnerability scanning (weekly), penetration testing (annual)

NIST SP 800-207: Zero Trust Architecture (ZTA)

Zero Trust = "Never trust, always verify." Every access request is authenticated, authorized, and encrypted, regardless of network location.

  • Micro-segmentation: Each microservice runs in isolated network segment with strict firewall rules
  • Continuous Authentication: Session tokens expire after 15 minutes, require re-authentication for sensitive operations
  • Least Privilege: API endpoints scoped to minimal necessary permissions (e.g., care coordinators cannot access admin functions)
  • Device Trust: Device posture checks (OS patching, antivirus status) before granting access
  • Monitoring: Real-time anomaly detection for unusual access patterns (e.g., bulk data downloads)

FBI CJIS Security Policy v5.9.1

While IHEP doesn't handle criminal justice data, we adopt CJIS-level security to demonstrate the highest standard of data protection (many HIV patients have justice system involvement due to stigma/discrimination history).

  • Advanced Authentication: Multi-factor authentication (MFA) mandatory for all users, biometric options available
  • Personnel Security: FBI fingerprint background checks for all staff with system access
  • Physical Security: Data centers with biometric access controls, 24/7 video surveillance, annual audits
  • Mobile Device Security: MDM (Mobile Device Management) with remote wipe capability, encrypted storage

NISTIR 8259A: IoT Device Security

IHEP integrates with IoT devices for patient monitoring (e.g., smart pill bottles for medication adherence, wearables for vitals). NISTIR 8259A provides device security baselines:

  • Device Identification: Unique cryptographic identity for each device, certificate-based authentication
  • Secure Updates: Signed firmware updates with rollback capability, automatic patching for critical vulnerabilities
  • Data Protection: Encrypted data transmission from device to platform, no storage of PHI on device
  • Logical Access: Disable unused ports/services, change default passwords, principle of least privilege

Patient Digital Twin Architecture

The Patient Digital Twin is a probabilistic computational model that mirrors the real patient's health state and continuously updates as new data arrives. It's the core innovation enabling personalized predictions and interventions.

Conceptual Foundation

What is a Digital Twin?

Originally from manufacturing (Boeing uses digital twins of aircraft engines to predict maintenance needs), a digital twin is a virtual replica that simulates the behavior of its physical counterpart. In healthcare, the "physical counterpart" is the patient's body, and the twin predicts disease progression, treatment response, and health risks.

Key Difference vs. Traditional ML: Most ML models make one-time predictions (e.g., "Will this patient be readmitted?"). A digital twin is stateful and recursive—it maintains a probabilistic belief about patient health that updates continuously as new observations arrive (lab results, medication changes, self-reported symptoms).

IHEP's Digital Twin Components

1. State Variables
  • CD4 count (immune health)
  • Viral load (HIV replication)
  • Medication adherence rate
  • Comorbidities (diabetes, hypertension)
  • Social determinants (housing stability, food security)
2. Probabilistic Model
  • Bayesian network encoding causal relationships
  • E.g., Poor adherence → higher viral load → lower CD4 count → increased opportunistic infections
  • Uncertainty quantification (95% credible intervals)
3. Update Mechanism
  • Bayesian inference: posterior = prior × likelihood
  • New lab result arrives → update beliefs about current state
  • Recursive loop: today's posterior = tomorrow's prior

Mathematical Framework: Recursive Bayesian Update

Core Update Equation

At each time step $t$, update the patient state estimate $\theta_t$ given new observation $\mathcal{D}_{t+1}$:

$$P(\theta_{t+1}|\mathcal{D}_{1:t+1}) \propto P(\mathcal{D}_{t+1}|\theta_{t+1}) \cdot P(\theta_{t+1}|\mathcal{D}_{1:t})$$

Where:

  • $\theta_{t+1}$ = Patient state variables at time $t+1$ (CD4, viral load, adherence, etc.)
  • $\mathcal{D}_{1:t+1}$ = All observations from time 1 through $t+1$ (cumulative clinical data)
  • $P(\mathcal{D}_{t+1}|\theta_{t+1})$ = Likelihood: How probable is the new observation given current state?
  • $P(\theta_{t+1}|\mathcal{D}_{1:t})$ = Prior: What did we believe about the state before seeing new data?
  • $P(\theta_{t+1}|\mathcal{D}_{1:t+1})$ = Posterior: Updated belief after incorporating new observation

Intuition: Learning from Every Data Point

Imagine a patient with previously stable viral load suddenly shows a spike in their latest lab result. The digital twin asks:

  • Prior belief: "This patient has been adherent and stable for 6 months" → low probability of viral rebound
  • New observation: Viral load jumped from <50 copies/mL to 1,200 copies/mL
  • Likelihood: "If patient is truly adherent, this spike has only 5% probability (maybe lab error). If patient became non-adherent, spike has 70% probability."
  • Posterior update: Increase probability of non-adherence, flag patient for adherence counseling intervention

The key is that the twin doesn't blindly trust the new data (could be lab error) or ignore it (could be real crisis). It rationally integrates the new signal with historical context.

Implementation: Particle Filter for Nonlinear Dynamics

HIV disease dynamics are highly nonlinear (viral replication, immune response, drug resistance mutations). Standard Kalman filters assume linear Gaussian dynamics; we use a particle filter (Sequential Monte Carlo):

  1. Initialize: Sample $N=1000$ particles (each is a plausible patient state) from prior distribution
  2. Predict: For each particle, simulate forward one time step using disease dynamics model (e.g., viral kinetics equations)
  3. Update: Weight each particle by likelihood of observed data given that particle's state
  4. Resample: Keep high-weight particles, discard low-weight ones. This concentrates computational effort on plausible hypotheses.
  5. Estimate: Posterior distribution = weighted ensemble of particles. Median = point estimate, spread = uncertainty.

This allows us to handle arbitrary nonlinearities, multimodal posteriors (e.g., "patient is either fully adherent or completely non-adherent, but not in between"), and uncertainty quantification critical for clinical decision support.

10-Year Roadmap to HIV/AIDS Functional Cure

While optimizing existing care delivers immediate value, IHEP's long-term moonshot goal is achieving a functional cure for HIV: sustained viral suppression without ongoing antiretroviral therapy (ART). This requires AI-driven therapeutic discovery targeting the viral reservoir.

Why a Cure is Needed (Despite Effective ART)

Modern ART reduces HIV to undetectable levels, but patients must take daily medication for life. The virus persists in latent reservoirs (resting CD4+ T cells, tissue macrophages) that ART cannot eliminate. If ART stops, viral rebound occurs within 2-4 weeks in 99% of patients.

  • Lifetime ART Burden: Cumulative cost $400K-600K per patient, daily medication adherence challenge, long-term toxicity (kidney damage, bone loss)
  • Stigma & Quality of Life: Daily reminder of disease status, disclosure challenges in relationships/employment
  • Global Access: ART requires healthcare infrastructure unavailable in many low-resource settings
  • The Cure Vision: One-time or intermittent treatment eliminates viral reservoir → sustained remission without ART
