Electronic Health Records (EHR) are digital versions of patients' paper charts. They contain 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 among healthcare providers. EHR systems improve the efficiency of healthcare delivery by enabling quick access to patient information. They also enhance patient safety by reducing errors related to handwriting or miscommunication. Additionally, EHRs can support data analysis for public health initiatives and research, contributing to improved healthcare outcomes and practices.
