Challenges & Solutions
Challenges
- Video visits must work on weak rural connections
- RPM devices stream vitals continuously at population scale
- PHI spans video, chat, documents, and device data
- Clinicians need EHR context inside the visit, not after
- No-show reduction requires reminders across SMS, email, and push
CloudFormation Solves
- Adaptive bitrate WebRTC with global TURN relays
- IoT ingestion pipeline with per-device authentication and alerting
- End-to-end KMS encryption with BAA-covered services only
- FHIR APIs pull problem lists and meds into the visit view
- Event-driven reminder engine with quiet-hours and escalation
Architecture Patterns
1
Virtual Visit
WebRTC media over global TURN. Waiting room and triage queue. In-visit chart summary via FHIR. Post-visit note drafted by ambient AI for clinician sign-off.
2
Remote Monitoring
Device gateway authenticates per-device certs. Streams land in time-series store. Rules engine raises alerts to care team queues with acknowledgment tracking.
3
Care Coordination
Task queues per care team. Secure messaging with PHI redaction on export. Referrals and orders integrated to partner systems via HL7/FHIR interfaces.
4
Compliance Layer
BAA-eligible services only. Access logging on every PHI touch. Automated retention and legal hold. Quarterly access reviews generated automatically.
