Introduction
Electronic Health Records (EHR) have transformed the healthcare landscape, replacing paper-based documentation with digital systems that streamline patient care delivery. An EHR is a systematic collection of electronic health information about individual patients or populations. Unlike electronic medical records, which contain medical information from a single practice, EHRs are designed to capture and share information across different healthcare settings, creating a comprehensive view of a patient's health journey.
The adoption of EHR systems represents one of the most significant technological advancements in modern healthcare. These digital records contain patients' medical history, diagnoses, medications, treatment plans, immunization dates, allergies, radiology images, and laboratory and test results. By digitizing health information, EHRs enable real-time access to patient data, improve care coordination, and enhance clinical decision-making.
