“What is #HIE anyway? Surfing through the alphabet soup of healthcare acronyms can be confusing. HIE generally means Health Information Exchange.
Electronic Health Records do not do much good if they are trapped in disparate silos that are unable to communicate with each other. To have ‘meaningful use’ of and Electronic Health Record (EHR) we need to develop Health Information Exchange (HIE). HIE will provide the capability to electronically move clinical information among disparate health care information systems while maintaining the meaning of the information being exchanged. The goal of HIE is to facilitate access to and retrieval of clinical data to provide safe, efficient and effective, timely, and fair, patient-centered care. HIE will also be useful to Public Health authorities to help in analyses of the health of the population.”
