Challenges & Solutions
Challenges
- Mental health records have the highest legal sensitivity under 42 CFR Part 2
- Video therapy sessions must be encrypted end-to-end with BAA coverage
- Crisis detection must trigger clinician alert within seconds of detection
- Patient privacy must be maintained during any AI-powered analysis
CloudFormation Solves
- 42 CFR Part 2 data isolation enforced — separate storage per consent grant
- Amazon Chime SDK HIPAA-eligible for encrypted video therapy sessions
- Lambda + Comprehend Medical for real-time crisis keyword detection in <30s
- De-identification pipeline is mandatory before any ML model training
Architecture Patterns
1
Video Therapy
Chime SDK (HIPAA-eligible) for encrypted sessions. No recording without explicit consent. KMS keys patient-controlled.
2
PHI Data Layer
Separate S3 buckets per patient with consent tracking. Aurora encrypted with patient KMS keys. No cross-patient access possible.
3
Crisis Detection
Real-time session analysis via Comprehend Medical → Lambda rule engine → SNS alert to clinician within 30 seconds.
4
Behavioral Analytics
Strict de-identification pipeline before any ML. Lake Formation audit log. SageMaker trained on de-identified cohort data only.
