An electronic health record (EHR) is a digital version of a patient’s paper chart. EHRs are secure, real-time records that make information such as medical history, diagnoses, medications, treatment plans, immunizations, allergies, test results, and more available instantly. EHRs are designed to share information with other health care providers, such as laboratories and specialists, so that important care information can be shared with all providers involved in the patient’s care.
