Medical records document a patient's medical history and are important for continuity of care, defending malpractice claims, research, and more. A medical record chronicles a patient's examinations, treatments, test results, medications, and other details. It benefits patients by facilitating further treatment, and benefits doctors, hospitals, and other professionals by allowing them to continue care where others left off. Key characteristics of good medical records include accuracy, completeness, timeliness, and authentication. Issues can include deficiencies, legal and ethical concerns, and challenges maintaining outdated or inactive records.
