LLM-based Agentic Systems in Healthcare¶

LLM-based agentic systems are transforming healthcare by combining the language capabilities of LLMs with the ability to process information, plan, decide, recall, reflect, interact, and leverage various tools. These systems represent a new paradigm in healthcare automation and decision support.

Key Capabilities¶

Natural language understanding and generation
Multi-modal data processing (text, images, signals)
Tool and API integration
Memory and context management
Collaborative decision-making
Continuous learning and adaptation

Clinical Workflow Automation¶

Automated clinical note drafting from doctor-patient conversations
Automated investigation order placement for clinician review
Compliance with standard operating procedures and guidelines
Estimated to automate up to 47% of labor tasks when equipped with tool use
Integration with real-time clinical workflows for note-writing and electronic ordering
Prediction capabilities for readmission rates and other clinical outcomes

Trustworthy Medical AI¶

Retrieval-augmented generation to reduce hallucinations
Integration with authorized hospital databases and clinical guidelines
Autonomous verify-rectify-verify processes for output validation
Enhanced reliability in clinical calculations
Framework for model auditing using expert insights and counterfactual images
Understanding AI reasoning processes in medical image classification

Ethical Considerations and Governance¶

Generative Artificial Intelligence in Healthcare: Ethical Considerations and Assessment Checklist

Provides a comprehensive framework for evaluating GenAI in healthcare applications: - TREGAI Github - DocX checklist

Key considerations: - Patient privacy and data security - Model transparency and interpretability - Fairness and bias mitigation - Clinical validation and safety - Regulatory compliance

Clinical Applications¶

Multi-Agent-Aided Diagnosis¶

Collaboration between specialist agents for complex cases
Mirrors multidisciplinary approaches in clinical practice
Particularly valuable for rare conditions or resource-limited settings
Automated identification of relevant specialist agents for case discussion

Medical Imaging and Diagnostics¶

Understanding the reasoning process of complex medical decisions

Uses counterfactual images and expert clinicians to understand AI reasoning in medical image classification, going beyond traditional saliency maps. The framework reveals that classifiers rely on both human-like features (lesional pigmentation patterns) and potentially undesirable features (background skin texture).

Foundation models for Retinas

Advanced models for retinal image analysis and diagnosis.

Patient Care Systems¶

Doctor GPT

Implements advanced LLM prompting for organizing, indexing and discussing medical PDFs without opinionated prompt processing frameworks.

Generative AI Pharmacist

A comprehensive system for processing and analyzing prescriptions through images and videos.

Democratization of health decision-making through personal AI agents
Patient-owned health data management and interpretation
Enhanced patient understanding and adherence to medical advice
Potential for direct researcher-patient data sharing
Need for regulatory approval and data infrastructure
Evolution towards AI as a healthcare colleague rather than just an assistant
