Prompt

System architecture diagram for a hospital management system. Patients access a portal for appointments and results; clinicians use a workstation for charting and orders. Core services should include EHR, scheduling, pharmacy, and billing/claims. Integrate with imaging (PACS) and external labs using HL7 v2 and FHIR APIs. Store clinical data in a secure database, index notes for search, and use a message bus for order events. Add MFA, audit trails, and HIPAA-aligned access controls.

Show all (12)
  • Patient & Clinician Access / Patient Portal: Provide self-service access; Collect intake forms; Notify patients
  • Patient & Clinician Access / Clinician Workstation: Document encounters; Place orders; Review history
  • Patient & Clinician Access / Access Gateway: Enforce policies; Terminate TLS; Log access
  • Clinical & Operational Services / EHR Service: Store clinical records; Expose FHIR APIs; Maintain audit history
  • Clinical & Operational Services / Scheduling Service: Coordinate appointments; Avoid conflicts; Send reminders
  • Clinical & Operational Services / Billing & Claims: Generate invoices; Validate coverage; Track payments
  • Data & Integration / Clinical Data Store: Encrypt data at rest; Support reporting; Maintain backups
  • Data & Integration / Integration Engine: Transform messages; Sync with partners; Handle retries
  • Data & Integration / Imaging & PACS: Store imaging studies; Serve radiology images; Link to encounters
  • Security & Compliance / Identity & MFA: Authenticate clinicians; Enforce MFA; Manage sessions
  • Security & Compliance / Audit & Monitoring: Track PHI access; Detect abuse; Support audits
  • Security & Compliance / Backup & DR: Protect data availability; Recover services; Meet RTO/RPO

Key flows

Show all (3)
  • Appointment flow: patients book slots in the portal, Scheduling Service reserves availability, and events notify clinicians through Kafka.
  • Clinical flow: clinicians chart in the EHR, data is stored in the encrypted clinical database, and relevant orders are routed via HL7/FHIR through the integration engine.
  • Billing flow: completed encounters trigger charge capture, Billing & Claims submits EDI claims, and payments are reconciled in the finance system.
