EMR (Electronic Medical Record) refers to a digital version of a patient's paper chart, primarily used by healthcare providers for diagnosis and treatment. It contains detailed information about a patient's medical history, medications, allergies, and test results, allowing for efficient management of patient care within a single practice. EHR (Electronic Health Record) is a more comprehensive digital record that includes all the information found in an EMR but is designed to be shared across different healthcare settings. EHRs facilitate coordinated care by allowing various providers to access a patient's complete health history, improving communication and continuity of care.
