According to the National Institute of Health, “Interoperability has been defined by the Institute for Electrical and Electronics Engineering in the IEEE Standard Computer Dictionary as ‘the ability of two or more systems or components to exchange information and to use the information that has been exchanged.’” On the other hand, ScienceDirect states, “Data integration involves mapping variables in different datasets together to form a combined dataset which can then be used to conduct different types of analyses.
Differences between interoperability and data integration
According to a report from the American Medical Association, healthcare interoperability lets doctors and healthcare providers easily share and understand patient information as it happens. It enables data exchange and use across systems and relies on standardized data formats and protocols to facilitate this communication.
Data integration, however, is centered on consolidating data from multiple sources into a single, unified system. The ScienceDirect article adds, “The process of data integration is to map two datasets together. Mapping two datasets will help compare a phenomenon in one dataset to that of a second dataset. This is especially important when examining databases that have different populations or different illnesses.”
For example, interoperability allows a hospital’s electronic health record (EHR) system to share patient records with a specialist’s clinic, ensuring continuity of care. In contrast, data integration might involve aggregating lab results, billing information, and patient records into a centralized database for analysis and reporting.
Does the distinction matter?
The distinction between interoperability and data integration in healthcare has implications for both patient care efficiency and regulatory compliance. For patient care, interoperability enables real-time coordination between healthcare providers, which is important given how frequently patients move between different facilities and providers. As a study from the NIH states, "the patient population is so transient now. Patients should have the ability to go where they want to go and our obligation is to take care of them and get it right.”
From a compliance and strategic perspective, healthcare organizations must address both interoperability and data integration needs. They face mandatory reporting requirements to multiple authorities at the county, state, and federal levels, including the CDC. Healthcare organizations must develop solutions that address both interoperability for seamless patient care and data integration for regulatory compliance and reporting.
How does interoperability and data integration work together?
While interoperability and data integration serve different purposes, they are complementary. A healthcare IT strategy incorporates data integration to unify information and interoperability to ensure seamless communication across different platforms. Together, they enhance data accessibility, improve decision-making, and drive better patient outcomes.
