A solution guide for evaluating AI infrastructure in API-first digital health products, including EHR integration, data access, workflow automation, and compliance controls.
Summary
API-first digital health AI should be evaluated as product infrastructure: data access, workflow ownership, write-back controls, audit logs, and PHI governance.
Workflow checkpoints
Product architecture
Digital health teams need to decide whether AI sits inside the product, beside the EHR, or across multiple data sources.
- Define source of truth and data ownership.
- Review API coverage and write-back controls.
- Track provenance and user actions.
Governance and scaling
AI features need operational controls before scaling to customers or care teams.
- Define model-training exclusions and retention.
- Monitor PHI access and support access.
- Build rollback and incident workflows.
Evaluation criteria
- API coverage, authentication, rate limits, webhooks, write-back controls, and sandbox support.
- PHI governance, BAA terms, audit logs, data retention, and support access.
- Integration with EHR, patient data infrastructure, workflow automation, and user review.
Platforms and infrastructure for building clinical workflows and healthcare applications.

Data access and interoperability
Tools that support record retrieval, HIE access, and healthcare data exchange.

Compliance considerations
- Review PHI flow, BAA terms, model-training exclusions, audit logs, and user permissions.
- Define human review before AI output affects care, billing, or patient communication.
- Validate incident response, support access, and rollback procedures before launch.

NIST SP 800-228 addresses API risk factors across development and runtime and recommends incremental, risk-based controls for cloud-native API protection; it is security guidance rather than certification of a platform or architecture. HL7 FHIR R4 defines standardized resources and RESTful interactions, while SMART App Launch defines authorization, scopes, launch context, user identity, access tokens, and related application flows for FHIR systems. ONC's standardized API test method evaluates specific certified Health IT Modules against named FHIR, US Core, SMART, and related requirements and states that third-party application registration is not application vetting. HHS cloud guidance explains that a cloud provider creating, receiving, maintaining, or transmitting ePHI on behalf of a regulated entity can be a business associate even when it cannot decrypt the data, and that customers must understand the service, perform risk analysis, assign safeguards and incident responsibilities, and execute applicable agreements. These sources do not define 'API-first' as a regulated category or prove complete interoperability, security, HIPAA compliance, clinical safety, scale, uptime, data rights, or workflow fitness. Buyers should inventory every public, partner, internal, administrative, webhook, batch, and event interface; identify owner, purpose, data classification, tenant and environment, source of truth, schema and version, authorization flow and scopes, service account, rate and quota, latency and availability target, write and delete behavior, idempotency, pagination, ordering, retries, error model, audit event, retention, deprecation, and support path. Product review should distinguish application identity, end-user identity, patient and encounter context, delegated access, background access, vendor support, and AI service access, granting only the resources and actions needed for each use. Acceptance testing should cover authentication and token rotation, revoked and expired access, overbroad and cross-tenant requests, object- and field-level authorization, malformed and oversized payloads, injection and schema abuse, enumeration, replay, duplicate webhooks, out-of-order events, partial failure, retry storms, rate limits, stale caches, version negotiation, bulk export, deletion, downtime, recovery, rollback, and dependency compromise. Data tests should preserve provenance through normalization and generated output, reconcile reads and writes end to end, and route uncertain identity, clinical, billing, or communication actions to accountable reviewers. Operations should monitor availability, latency, error and rejection rates, authorization failures, quota use, webhook lag, retry volume, data-quality exceptions, unusual access, support access, dependency and model changes, and incidents, with stable denominators and customer-specific service boundaries. Contracts should address BAA and subcontractor scope where applicable, permitted data use and model training, security testing, vulnerability and incident notice, service levels, change and deprecation notice, version support, raw-data access, audit export, portability, deletion, transition assistance, and tested vendor exit. A sandbox, FHIR endpoint, successful conformance test, API documentation, or BAA does not by itself establish production safety, least privilege, complete data, accurate semantics, regulatory compliance, or an effective care workflow.
