AI-Enhanced Longitudinal Patient Profiles: Connecting Episodes of Care Across Settings

Healthcare organizations in the United States generate vast volumes of patient data every day—yet transforming this information into a unified, reliable patient narrative remains highly challenging. Clinical histories are scattered across hospitals, clinics, laboratories, payers, and digital health platforms, creating fragmented records that undermine care continuity, increase administrative waste, and expose clinicians to serious safety and liability risks.

Artificial Intelligence (AI) and Machine Learning (ML) are reshaping patient identity resolution and longitudinal record creation. Moving beyond traditional probabilistic matching, it explores AI-driven referential matching, privacy-preserving record linkage (PPRL), and generative intelligence as the foundation for building a true “Single Source of Truth” for patient data.

By enabling accurate identity resolution across systems, AI-powered longitudinal profiles transform disconnected episodes of care into a cohesive clinical narrative—supporting safer decision-making, stronger compliance, reduced revenue leakage, and the advancement of value-based care.

What This White Paper Explores

• Why fragmented patient identities remain the single greatest technical barrier to interoperable care
• The operational, financial, and clinical risks created by duplicate and mismatched records
• The evolution from probabilistic matching to AI-driven referential identity resolution
• How privacy-preserving record linkage enables research and population health without exposing PII (Personally Identifiable Information)
• The role of generative AI in synthesizing longitudinal records into clinician-ready insights
• Legal, ethical, and regulatory considerations shaping patient identity in the era of TEFCA (Trusted Exchange Framework and Common Agreement)

Why It Matters

Designed for healthcare executives, informatics leaders, compliance teams, and clinical stakeholders, this white paper provides a strategic blueprint for moving from fragmented data silos to AI-driven patient identity intelligence. It demonstrates how accurate, longitudinal patient records are no longer just an interoperability goal but a foundational requirement for safe, efficient, and accountable care delivery.
