Electronic Health Record (EHR) interoperability refers to the ability of different healthcare systems and software applications to exchange and share patient health information seamlessly. It enables the secure and efficient sharing of patient data across various healthcare entities, such as hospitals, clinics, pharmacies, and laboratories. Interoperability allows healthcare providers to access comprehensive and up-to-date patient information regardless of the system or software used, promoting coordinated care, improved patient outcomes, and streamlined healthcare workflows. Achieving EHR interoperability involves adopting standardized data formats, communication protocols, and interfaces to facilitate the exchange of health information between disparate systems, ultimately enhancing the overall quality and continuity of patient care.
