The FHIR Interoperability & Security Infrastructure module forms the digital backbone of the DecisionDoc EHR platform.
It enables authorized, standards-based exchange of health information across providers, laboratories, and billing systems—while enforcing the strictest levels of privacy, encryption, and authentication under HIPAA, HITECH, and the ONC Cures Act.
Every clinical record, transaction, and audit event within DecisionDoc flows through this security architecture.
By combining FHIR-standard interoperability with DecisionDoc’s patented algorithmic validation framework, the system ensures that every exchange is accurate, compliant, and legally defensible—without compromising privacy or performance.
FHIR (Fast Healthcare Interoperability Resources) is the foundation of DecisionDoc’s data architecture.
Each patient record, lab result, claim, and encounter exists as a standardized FHIR resource—allowing seamless interaction across systems and organizations.
Within this framework, the patented DecisionDoc algorithm acts as an internal validation layer, confirming record integrity, code accuracy, and completeness before data is shared externally.
This unified design replaces fragmented, proprietary interfaces with a single, compliant data model connecting hospitals, payers, labs, and partner EHRs.
Patient & Practitioner:
Demographics, identifiers, and credentials
Encounter & Observation:
Visit data and clinical measurements
ServiceRequest & DiagnosticReport:
Laboratory orders and interpreted results
Claim & ExplanationOfBenefit:
Billing and adjudication data
AuditEvent & Provenance:
immutable logging of data access and modification
All transactions occur through secure RESTful APIs validated against FHIR conformance profiles and verified by the patented algorithm for data integrity and medical-necessity compliance.
DecisionDoc’s layered security model employs multi-point validation and proactive breach prevention:
Encryption in Transit and at Rest
All PHI and financial data are encrypted using TLS 1.3 during transmission and AES-256 for storage.
OAuth 2.0 & OpenID Connect Authentication
Access is granted via a unified SSO gateway with multi-factor verification. Tokens are short-lived and scoped by user role to prevent privilege escalation.
Role-Based Access Control (RBAC)
Granular permissions follow HIPAA’s minimum necessary principle, ensuring each user accesses only what is required for their role.
Continuous Audit Logging
Every read, write, or export event is timestamped and stored as a FHIR AuditEvent resource. Compliance and incident reports can be generated instantly.
Algorithmic Anomaly Validation
The patented DecisionDoc algorithm supplements anomaly detection, flagging unusual query or export patterns for review—helping prevent unauthorized data aggregation or exfiltration.
DecisionDoc connects directly to national and regional Health Information Exchanges (HIEs), enabling authorized sharing of validated records in real time.
Each exchange is fully logged under a FHIR AuditEvent object, capturing when, by whom, and under what authorization data was shared.
Before transmission, the DecisionDoc algorithm confirms that each dataset aligns with payer, documentation, and necessity standards.
For research, analytics, or population-health use cases, DecisionDoc supports Bulk FHIR Data Export (Flat FHIR / Bulk Data API).
Authorized administrators can export de-identified or limited datasets for approved purposes, verified by DecisionDoc’s patented validation routines for accuracy and PHI compliance.
Exports filtered by encounter type, date range, or location
PHI removal compliant with NIST SP 800-122 de-identification guidelines
All exports require logged authorization, two-factor approval, and algorithmic verification prior to release
This process ensures no incomplete or identifiable record leaves the system without full audit-level verification.
DecisionDoc’s FHIR and security framework adheres to all major U.S. regulatory standards:
All configurations, audits, and incident responses are documented for continuous readiness and external certification.
The FHIR Infrastructure underpins every DecisionDoc module:
Encounter Intelligence:
Transfers algorithm-verified encounter data into billing-ready form.
Clinical Intelligence Core:
Reads FHIR Observations for reasoning without duplicating PHI.
Diagnostics Integration:
Exchanges lab orders and results via FHIR ServiceRequest and DiagnosticReport.
RCM Intelligence:
Uses FHIR Claim and ExplanationOfBenefit resources for payment tracking.
Patient Engagement:
Connects securely through the FHIR Patient Access API.
This microservices architecture scales effortlessly across enterprise environments while maintaining fault tolerance, load balancing, and continuous compliance.
Patients can securely retrieve their information through DecisionDoc’s FHIR Patient Access API, compliant with the ONC Cures Act Final Rule.
Access requires multi-factor identity verification, and all retrieval events are permanently logged.
Before release, the DecisionDoc algorithm verifies record completeness and data integrity—ensuring patients receive accurate, traceable health information.
This transparent design enhances patient trust while meeting national interoperability mandates.
Audit logs and access records retained for a minimum of six years (HIPAA requirement)
Disaster recovery backups encrypted and geographically redundant
Updates follow documented change-management and rollback protocols
Annual third-party penetration tests ensure ongoing defense performance
Continuous monitoring aligned with OIG Health IT Compliance Guidance
Guarantees interoperability across EHRs, laboratories, and payers
Validates every exchange through patented algorithmic verification.
Reduces administrative overhead via unified data standards
Provides immutable, verifiable audit trails for all transactions
Strengthens patient confidence through transparency and controlled access
