What does Query-based Exchange (HIE) allow?

Query-based Exchange (HIE) serves the critical function of enabling healthcare providers to find and request pertinent information about a patient from other providers. This capability is foundational in ensuring that care is coordinated effectively, as it allows a physician to access patient medical histories, medications, allergies, and other vital health data that may reside in different healthcare systems. This exchange improves clinical decision-making by providing timely and comprehensive patient information, especially crucial in situations where a patient's current provider may not have complete data on their medical history.

Other options, while relevant to healthcare information systems, do not directly capture the primary purpose of Query-based Exchange. For example, while securely storing patient information is important (and is a function of health information systems in general), it doesn't relate to the querying feature of HIE. Likewise, receiving information from patients might pertain more to direct patient communication and engagement rather than the exchange of data across providers. Executing emergency care protocols is about immediate clinical processes rather than the information exchange facilitated by HIE. Thus, the ability to locate and request existing information from other healthcare providers is the key benefit of a Query-based Exchange, enhancing the overall quality of patient care.
