Challenges and Solutions for Healthcare Data Interoperability: Towards a Holistic View using FHIR and HIEs
Interoperability woes still plague healthcare in 2026. Here's what to
Summary
Healthcare providers face the major challenge of data siloing from multiple Electronic Health Record (EHR) systems. Experts emphasize that utilizing standardized APIs (especially those based on FHIR) and regional Health Information Exchanges (HIEs) are essential to achieve comprehensive and safe healthcare delivery.

The fragmentation of data remains a significant hurdle in healthcare, particularly as the EHR landscape is dominated by a small number of vendors. Achieving interoperability requires integrating data from multiple disparate systems. Experts stress that this issue impacts all technological implementations, including AI solutions and simulation models. Ideally, patient care information—such as biopsy results following cancer imaging—should be seamlessly shared among various specialists (pathologists, radiologists, oncologists) using messaging standards like HL7. However, the reality often falls short of this ideal. To bridge this gap, building robust, standards-based API programs is crucial, with open APIs built on FHIR providing flexibility for connecting third-party tools. Beyond technology, achieving interoperability requires a holistic view encompassing both technology and human workflows. Key strategies include improving data quality at the source (e.g., check-and-balance systems during patient check-in) and connecting to Health Information Exchanges (HIEs). HIEs function as shared repositories, ensuring that a patient's history follows them rather than being trapped in a single system. Furthermore, removing organizational barriers between parent and subsidiary entities is necessary to provide complete visibility for comprehensive assessments. Ultimately, the integration of connected tools and access to diverse data sources via HIEs are vital steps toward creating an accountable, transparent, and efficient healthcare delivery system.
