An Electronic Health Record (EHR) is a digital version of a patient's paper chart. It contains comprehensive information about a patient's medical history, including diagnoses, medications, treatment plans, immunization dates, and test results. EHRs are designed to be shared across different healthcare settings, allowing for better coordination of care. EHRs improve the efficiency of healthcare delivery by providing real-time access to patient data for healthcare providers. They can enhance patient safety by reducing errors, streamline administrative processes, and support clinical decision-making. Additionally, EHRs can facilitate communication between patients and providers through patient portals, promoting better engagement in health management.
