Which document provides a summary of a patient's medical history?

The document that provides a summary of a patient's medical history is the Problem List. This list is crucial in clinical practice as it offers a concise view of a patient's current and past health issues, including diagnosed conditions, unresolved problems, and any relevant medical history that may affect current treatment. It serves as a quick reference for healthcare providers, helping them to easily identify the key medical issues of a patient at a glance.

In contrast, while the SOAP note is a structured format for documenting patient encounters, it focuses on subjective and objective findings, assessment, and plan rather than summarizing the entire medical history. The Assessment report provides an evaluation of a patient's condition but does not encapsulate the full history like a Problem List. Progress notes track patient treatment and responses over time, rather than consolidating past medical history into a summary. Hence, the Problem List is the most appropriate document for summarizing a patient's medical history.
