What term describes the ability of one information system to exchange data with another information system?

The term that describes the ability of one information system to exchange data with another information system is interoperability. This concept is fundamental in the field of health informatics and data management, as it ensures that different systems can communicate and share data seamlessly. Interoperability allows for the integration of different healthcare technologies and systems, facilitating efficient data exchange which is crucial for coordinated patient care, accurate reporting, and overall improvement in health outcomes.

When systems are interoperable, they can understand and interpret the data being shared, regardless of the systems' underlying technologies or formats. This capability is essential for achieving a cohesive healthcare environment where information can flow freely and effectively among various stakeholders, including providers, payers, and patients.

The other terms, while related to information systems, do not specifically capture this ability to exchange data. Compatibility refers to the ability of systems to work together, but it doesn't specifically denote data exchange. Portability involves the ease with which data can be transferred or adapted across systems but does not encompass the communication aspect. Integration typically refers to combining different systems into a cohesive whole but does not inherently imply that those systems can exchange data without prior integration work. Thus, interoperability is the most accurate term in this context.
