Front desks and call centers in hospitals juggle complexity that legacy IVRs cannot handle
Generic chatbots can't integrate safely with hospital information systems or uphold escalation, audit, and PHI controls.

SFMSS
Service-Flow-aware Medical Scenario Simulation
Multi-agent simulation generates patient/receptionist/service-flow dialogues for supervision and stress tests. Published in NAACL 2025 Findings.
HIS Integration
Hospital Information System Connectivity
PIORS is designed to collaborate with HIS for patient-specific answers and actions — demographics, appointment lookups, scheduling with strict RBAC.

EXAMPLE_POLICIES
Emergency Detection
"I'm not a clinician, but I can quickly connect you. If you think this could be an emergency, please call your local emergency number now."
Identity Verification
"Before I discuss appointments, I'll verify your date of birth. You can also say 'human' anytime to speak with staff."
Scheduling Confirmation
"I found Dr. Rao on Tue 10:40. Shall I book it and text you the prep instructions?"
Safety Guardrails
Non-Negotiable Controls
1
Identity & PHI
Verify caller using multi-factor cues (DOB + last name + OTP)
All PHI stays on-prem/VPC
Redact transcripts for analytics
2
Clinical Boundaries
No medical advice, triage, or interpretation
Reception scope only — route clinical matters to nurse line
Refusal templates for clinical advice
3
Emergency Handling
Emergency phrases (chest pain, bleeding) → immediate escalation
Safety filters on prompt & output
Instruct to call local emergency number
4
Audit & Logging
Log: audio hash, ASR text, intents, tool calls
Immutable decision log for every operation
