What does ROS refer to in a medical assessment?

In a medical assessment, ROS refers to the "Review of Systems." This is a systematic approach used by healthcare providers to gather information about the patient's overall health by evaluating each body system. During a ROS, the clinician typically asks questions related to various systems such as cardiovascular, respiratory, gastrointestinal, and neurological, among others, to identify any additional symptoms the patient may be experiencing that are not directly related to their presenting complaint. This comprehensive review helps to ensure that the clinician does not overlook any potential health issues and allows for a more thorough understanding of the patient's condition.

The other options pertain to different aspects of medical evaluations. The "Rate of survival" is a statistic often used in epidemiology or outcome studies, while "Resolution of symptoms" indicates the diminishing or complete alleviation of symptoms, and "Range of motion" refers specifically to the degree of movement available in a joint or group of joints. However, none of these accurately describes the systematic assessment process that the Review of Systems entails.
