What does the Review of Systems (ROS) entail?

The Review of Systems (ROS) is a critical component of the patient evaluation process, serving as a systematic inquiry about the functioning of various body systems. It involves gathering a comprehensive account of the patient's health status across multiple organ systems through a series of targeted questions. This process helps the clinician identify any underlying health issues that may not be immediately apparent during the physical examination or patient history.

For example, during the ROS, a healthcare provider might ask about symptoms related to specific systems such as cardiovascular, respiratory, gastrointestinal, and others, which can provide essential clues regarding the patient's overall health and guide further investigation or management. This proactive approach ensures that a multitude of potential conditions is considered, thereby enhancing the accuracy of clinical assessments and contributing to effective patient care.
