An Electronic Health Record (EHR) is a digital version of a patient's medical history that healthcare providers can access and update in real time. It stores information such as diagnoses, medications, treatment plans, allergies, lab results, and immunization records. EHR software helps hospitals and clinics streamline patient care, reduce paperwork, improve accuracy, and enable faster decision-making. By centralizing patient data, Electronic Health Records enhance communication between healthcare professionals and improve the overall quality of care.
