A systematic record and documentation of a patient's health experiences, conditions, treatments, and related information used to inform clinical decision-making and provide continuity of care.

Medical History

A medical history is a comprehensive account of a patient's health journey, serving as a crucial foundation for healthcare delivery and clinical decision-making. This systematic documentation encompasses both past and present health information, creating a timeline of medical events and observations.

Past medical conditions and surgeries
medications and allergies
Family health history
Social history and lifestyle factors
Review of systems (ROS)

Documentation Methods

Electronic Health Records (EHR)
Paper-based records (historical)
Patient portals and digital interfaces
medical-coding systems for standardization
