What is an electronic health record (EHR)?

An electronic health record (EHR) refers to a comprehensive digital version of a patient's paper chart. This digital format allows for the efficient storage, retrieval, and management of health information related to a patient’s medical history, diagnoses, treatment plans, medications, allergies, lab results, and other relevant data.

The importance of EHRs lies in their ability to provide a complete and up-to-date view of a patient’s health, facilitating better decision-making and improving the quality of care provided.
