Number of health information exchanges by state

Health information exchanges (HIEs) allow healthcare organizations and providers to electronically share a patient’s medical information within a healthcare system, community, or region. Interoperable systems such as HIEs give healthcare providers access to a patient’s medical record regardless of where the patient is receiving care. Such access to medical history can help providers deliver safe and effective care.
