HIS Update (FHIR)
| Feature | H-ADMINSIM Insight |
|---|---|
| Tool-based vs. Reasoning-based Scheduling | Tool-based scheduling (T) achieves significantly higher success rates (up to 75.9 percentage points lower for reasoning) than purely reasoning-based (R) methods for appointment scheduling. This highlights the critical role of structured tools in ensuring accuracy and reliability. |
| Patient Intake Bottleneck | Patient intake, particularly department assignment, remains the primary bottleneck for LLM-based administration. Its success rate varies significantly across hospital levels and depends on factors like prior diagnosis availability and conversation length. |
| Impact of Prior Diagnoses | Intake success rates improve when patients have prior diagnoses, which aid in more accurate department recommendations. Longer dialogues also contribute to better performance by allowing for refined symptom descriptions. |
| Model-Specific Strengths | Gemini 2.5 Flash demonstrated the strongest overall performance in tool-based scheduling and intake (especially with prior diagnoses). GPT-5 Mini shows strong reasoning but struggles with patient agent completeness in intake, while GPT-5 Nano often suffers from incorrect tool selection. |
Patient Intake
Primary Bottleneck for LLM Automation
While tool-based scheduling is highly effective, the complexity of patient intake, especially department assignment under uncertainty, remains the most challenging aspect for LLM-driven administrative automation.
FHIR Integration: A Standard for Interoperable Healthcare AI
H-ADMINSIM leverages the Fast Healthcare Interoperability Resources (FHIR) standard (R5) to ensure a unified and interoperable environment. This integration allows for realistic representation and exchange of medical data (Patient, Practitioner, Schedule, Slot, Appointment resources), enabling seamless testing of administrative workflows across heterogeneous hospital settings. FHIR's role is crucial for future LLM-driven automation deployment in diverse healthcare institutions, mitigating data inconsistency and enhancing data exchange efficiency.

Patient Profile Generation (Diseases, Preferences)
| Feature | H-ADMINSIM Approach |
|---|---|
| Hospital Levels | Simulates primary, secondary, and tertiary hospitals with distinct institutional characteristics, including varying department counts, physician numbers, and time units (e.g., 0.05 vs. 0.25 hours). |
| Physician Schedules & Capacity | Generates realistic physician profiles with variable working days and capacities (patients per hour), pre-filling busy schedules and appointments to create dynamic availability. |
| Patient Diversity | Creates diverse patient profiles based on 194 disease-symptom pairs, including diagnostic history (with/without prior diagnoses) and a range of scheduling preferences (asap, physician, date). |
| Temporal Realism | Incorporates temporal flow, updating appointment statuses (scheduled, in-progress, completed) and enabling rescheduling/cancellation only for scheduled appointments, reflecting real-world constraints. |

Synthetic Data for Ethical Development
H-ADMINSIM uses exclusively synthetically generated patient profiles and clinical data, containing no real-world identifiable medical information. This design choice eliminates privacy infringement risks during development and evaluation, setting a strong foundation for ethical AI research in healthcare.
Responsible AI Deployment in Healthcare Administration
While H-ADMINSIM uses synthetic data for development, real-world deployment of LLM-driven administrative solutions necessitates strict adherence to institutional data governance and privacy regulations. Key safeguards include robust data de-identification, stringent access controls, continuous auditing, and the potential for deploying local LLMs within on-premise hospital infrastructure to mitigate external data leakage. Future work needs to extend the framework to broader clinical scenarios and more intricate administrative processes for comprehensive applicability.
