Review of systems

The review of systems (ROS) serves as a final screening for significant symptoms after the other parts of the history have been obtained. In this section, the patient is asked about experiencing symptoms relevant to different functional organ systems of the body (for example, gastrointestinal, cardiovascular, and pulmonary). An emphasis is placed on organ systems and symptoms relevant to the chief complaint. Symptoms for as many as 14 different organ systems may be touched upon.
