Agentic AI in Healthcare & Medicine: A Seven-Dimensional Taxonomy for Empirical Evaluation of LLM-based Agents
Large Language Model (LLM)-based agents are transforming healthcare, from EHR analysis to treatment planning. This paper addresses a gap in the literature by presenting a seven-dimensional taxonomy, comprising 29 sub-dimensions, for the empirical evaluation of LLM-based agents in healthcare. Based on a review of 49 studies, the analysis reveals asymmetries in capability prevalence, with strong performance in retrieval-grounded advising but significant gaps in adaptation and compliance. This work establishes a baseline for developing robust, reliable, and ethical agentic AI systems for healthcare.

Deep Analysis & Enterprise Applications
Select a topic to dive deeper, then explore the specific findings from the research, rebuilt as interactive, enterprise-focused modules.
Cognitive Capabilities
Agents must translate clinical goals into actions. This involves planning, input processing (perception), execution, self-monitoring (meta-capabilities), and conflict resolution. While perception and action show progress, planning, meta-capabilities, and conflict resolution remain underdeveloped, risking fragmented care and unsafe recommendations.
Knowledge Management
Focuses on how LLM agents use internal and external knowledge. External Knowledge Integration is strong (~76% implemented), but Memory Modules are partially implemented (~49% partial, ~33% fully), and Dynamic Updates & Forgetting is critically low (~2% implemented). This highlights a need for better knowledge currency and hygiene.
Interaction Patterns
Describes how agents interact, manage context, and recover from errors. Conversational Mode is prevalent (~43% fully implemented), but Event-Triggered Activation (~92% not implemented), Human-in-the-Loop (~86% not implemented), and Error Recovery (~96% not implemented) are severely lacking. Robust systems need event-driven activation, explicit human checkpoints, and comprehensive error handling.
Adaptation & Learning
Addresses agents' ability to remain calibrated to evolving data and tasks. Drift Detection & Mitigation is almost entirely absent (~98% not implemented), Reinforcement-Based Adaptation is sporadic (~84% not implemented), and Meta-Learning & Few-Shot is rare (~78% not implemented). This indicates a critical need for continuous adaptation to preserve safety and auditability in dynamic clinical environments.
Safety & Ethics
Essential for preventing unsafe behaviors and ensuring equitable, private, and compliant operation. Safety Guardrails & Adversarial Robustness (~65% not implemented), Bias & Fairness (~65% not implemented), and Regulatory & Compliance Constraints (~86% not implemented) are significantly underdeveloped. Privacy-Preserving Mechanisms show stronger footing (~18% fully implemented) but are not universal. Bridging these gaps is crucial for clinical adoption.
Framework Typology
Delineates the structural and operational blueprints. Multi-Agent Design is broadly mature (~82% fully implemented), indicating role-based compositions are a default pattern. Centralized Orchestration, however, clusters in partial territory (~57% partially implemented), suggesting coordination layers exist but often lack full global state management or auditable sequencing.
Core Tasks & Subtasks
Defines the operational responsibilities. Information-centric tasks like Clinical Documentation & EHR Analysis (~45% fully implemented) and Medical Question Answering & Decision Support (~57% fully implemented) are mature. However, action and discovery-oriented tasks such as Treatment Planning & Prescription (~20% fully implemented) and Drug Discovery & Clinical Trial Design (~18% fully implemented) show substantial gaps. Benchmarking & Simulation Environment is robust (~80% fully implemented).
76%
of LLM agents implement External Knowledge Integration (Knowledge Management)
This highlights widespread pairing of parametric recall with authoritative external sources at inference time, a strong foundation for grounded clinical reasoning.

Align outputs with evolving guidelines
The process for Dynamic Updates & Forgetting is crucial but currently lacking in most LLM-based agents in healthcare. Only 2% of surveyed studies fully implement this, leading to static knowledge accumulation and outdated recommendations.
| Capability | Implemented (✓) | Partially Implemented (△) | Not Implemented (X) |
|---|---|---|---|
| Planning | 55% (△) | 45% (X) Many systems still lack robust mechanisms for long horizon task decomposition, risking fragmented care pathways and missed contingencies. |
|
| Perception (Input Processing) | 46% (✓) | 55% (△) | Robust pipelines integrating multiple modalities are seen, but partial implementations with limited fusion are more common. |
| Action (Output & Execution) | 41% (✓) | 8% (△) | Many systems lack advanced execution layers, with only basic API calls or text outputs. |
| Meta-Capabilities | 53% (X) Many systems lack explicit critique and revision loops, or calibrated uncertainty estimates, leading to poor self-monitoring. |
||
| Consistency & Conflict Resolution | 61% (X) Scarce conflict resolution pipelines, inviting contradictory chart updates or unsafe recommendations. |
The Challenge of Adaptation & Learning in Healthcare AI
Figure 8 shows uniformly low adoption across Adaptation & Learning dimensions. For instance, Drift Detection & Mitigation is essentially absent with 98% of studies not implementing it. This means most agents would not notice, let alone correct, shifts in codes, templates, or patient mix, leading to quiet performance erosion. Similarly, Reinforcement-Based Adaptation is sporadic (~10% implemented), and Meta-Learning & Few-Shot is rare (~20% implemented). These figures indicate critical gaps in lifecycle instrumentation, preference learning, and end-to-end designs that fuse few-shot competence with continuous monitoring. Bridging these gaps is vital for dependable systems.
86%
of LLM agents NOT implementing Regulatory & Compliance Constraints
This reflects procedural assurances rarely appearing as verifiable runtime gates, hindering clinical accountability and trust. Bridging this gap from intent to assurance is crucial for real-world deployments.
| Dimension | Fully Implemented (✓) | Partially Implemented (△) | Not Implemented (X) | Observation |
|---|---|---|---|---|
| Multi-Agent Design | ~82% | ~16% | Role-based compositions (planner, retriever, verifier) are now the default pattern. | |
| Centralized Orchestration | ~57% | Coordination layers exist, but many lack fully realized controllers with global state, policy enforcement, and auditable sequencing. |
80%
of LLM agents include Benchmarking & Simulation Environment
This highlights broad adoption of standardized datasets and realistic simulators, boosting comparability and iteration speed for LLM agents in healthcare.
Core Task Maturity: Information-Centric vs. Action-Oriented
Figure 11 highlights a clear divide in the maturity of core tasks. Information-centric tasks like Clinical Documentation & EHR Analysis (~45% implemented) and Medical Question Answering & Decision Support (~57% implemented) are leading in maturity, showing readiness for frontline utility. Conversely, action and discovery-oriented areas such as Treatment Planning & Prescription (~20% implemented) and Drug Discovery & Clinical Trial Design (~18% implemented) still show substantial gaps. This pattern suggests that while agents excel at retrieval-grounded advising, safe automation of judgment and longitudinal interaction requires significant governance advances.
