Care coordination is the deliberate organization of patient care activities between two or more participants (including the patient) involved in a patient's care to facilitate the appropriate delivery of health care services. Organizing care involves the marshaling of personnel and other resources needed to carry out all required patient care activities and is often managed by the exchange of information among participants responsible for different aspects of care.  Interoperable health IT that is patient-centered makes the right data available to the right people at the right time across products and organizations, and in a way that can be relied upon and meaningfully used by recipients. The ability to seamlessly share health information is essential to building a patient-centered interoperable health IT ecosystem in the United States to facilitate coordination of care.
