Among the hottest topics in healthcare and technology today is the concept of interoperability – and we are ready to boldly make the case that it is not just a buzzword, but rather a progressive movement in healthcare information technology (HIT) worldwide. The essence of interoperability set forth in layman’s terms by Scott Wallace, JD, MBA, is simply, “personal health information, entered into a system once, becomes available to patients wherever they are and whenever they need it.” Today, the mandate for electronic health records (EHRs) is the driving force behind this concept, helping to advance population health and information management to achieve improved outcomes across the healthcare ecosystem.
On April 5, 2013, the HIMSS Board approved the following definition of interoperability: In healthcare, interoperability is the ability of different information technology systems and software applications to communicate, exchange data, and use the information that has been exchanged. Data exchange schema and standards should permit data to be shared across clinicians, lab, hospital, pharmacy, and patient regardless of the application or application vendor. Interoperability means the ability of health information systems to work together within and across organizational boundaries in order to advance the effective delivery of healthcare for individuals and communities.
The description includes three definitive levels of HIT interoperability, including:
Foundational Foundational interoperability allows data exchange from one information technology system to be received by another and does not require the ability for the receiving information technology system to interpret the data. One can think of foundational interoperability as serving as the base of a communications pyramid, offering the most basic of data exchange services.
Structural Structural interoperability is an intermediate level that defines the structure or format of data exchange where there is uniform movement of healthcare data from one system to another such that the clinical or operational purpose and meaning of the data is preserved and unaltered. Structural interoperability defines the syntax of the data exchange, ensuring that data exchanges between information technology systems can be interpreted at the data field level.
Semantic Semantic interoperability provides interoperability at the highest level, which is the ability of two or more systems or elements to exchange information and to use the information that has been exchanged. Semantic interoperability takes advantage of both the structuring of the data exchange and the codification of the data including vocabulary so that the receiving information technology systems can interpret the data. This level supports the electronic exchange of patient summary information among caregivers and other authorized parties via potentially disparate EHR systems and other systems to improve quality, safety, efficiency, and efficacy of healthcare delivery.
According to the latest data brief from the Office of the National Coordinator for Health IT in 2015, 52 percent of hospitals can electronically find patient health information, 85 percent can send patient summary of care records, 65 percent can receive such records and 38 percent can use or integrate those records into their own EHRs without manual entry. Additionally, more than a quarter conduct all four of these key domains of interoperability, up from 23 percent, in 2014. As additional government mandates and successful patient and clinician outcomes emerge, interoperability will continue to infiltrate the healthcare ecosystem, shifting from its state as a buzzword to an industry fundamental.
