Health Information Exchange Systems (HIES) encompass the technological infrastructure and platforms that facilitate the electronic sharing of health-related information among different healthcare organizations and systems. These systems are critical to supporting Health Information Exchange (HIE), allowing for the secure and standardized transfer of patient data across disparate healthcare entities.

HIES enable healthcare providers to access and exchange a patient’s health data, including history, prescriptions, diagnoses, and test results, in a seamless and interoperable manner. The goal is to enhance care coordination, reduce redundancies, and improve the overall efficiency and quality of healthcare delivery. HIES typically adhere to privacy and security standards to protect patient information during the exchange process.
