Adult Review of Systems (ROS)

Overview

The review of systems (or symptoms) is a list of questions, arranged by organ system, designed to uncover dysfunction and disease. It can be applied in several ways:

  1. As a screening tool asked of every patient that the clinician encounters.
  2. Asked only of patients who fall into particular risk categories (e.g. reserving questions designed to uncover occult disease of the prostate to men over 50).
  3. To better define the likely causes of a presenting symptom, as described in the HPI section (e.g. patients w/a chief concern of "chest pain" would be asked detailed cardiac and pulmonary ROS).

So, what's the best way to use the ROS? I have always been dubious of its utility as a broadly applied screening tool. Using it in this fashion makes sense if the following hold true:

  1. The questions asked reflect an array of common and important clinical conditions
  2. These disorders would go unrecognized if the patient was not specifically prompted
  3. The identification of these conditions then has a positive impact on morbidity/mortality

Unfortunately, aside from a few very specific screening tools (e.g. perhaps depression), there is little evidence to support these assumptions. In fact, positive responses to a screening ROS are often of unclear significance, and may even create problems by generating a wave of additional questions (and testing) that can be of low yield. For these reasons, many clinicians (myself included) favor a more targeted/thoughtful application of ROS questions, based on patient specific characteristics (e.g. age, sex) and risk factors (e.g. history of diabetes → vascular ROS). This strategy, I think, is both more efficient and revealing. As you gain experience, you can make an informed decision about how you'd like to incorporate the ROS into your overall patient care strategy.

It's important to realize that historical Q&A is just one piece of the clinical puzzle. Patient's responses must be interpreted within the context of the rest of their profile, including: risk factors, past history, and exam findings. For example, a patient who has chest pain would be asked re: duration, precipitating events, severity, characterization, radiation, associated symptoms, etc. In addition, an assessment of cardiac risk factors and an organized search for exam findings indicative of vascular disease (e.g. elevated BP, diminished peripheral pulses, audible bruits, etc) would be very relevant. On the basis of the sum of this data, the clinician can come to an informed conclusion about the importance/cause of this patient's chest pain (e.g. angina, heartburn, pulmonary embolism, etc), and use it to guide their subsequent decision making.

Guide To Using This ROS

There is no ROS gold standard. What follows is a much more extensive screening question list then would generally be used. The breadth of questions included is somewhat arbitrary, based on my sense of the most commonly occurring illnesses and their symptoms. There is also some redundancy, as the same symptoms often apply to multiple organ systems. Feel free to edit/adapt to fit your clinical needs. Realize that exotic or regional illnesses might require other ROS questions. In addition, some sub-specialty areas use an expanded ROS, specific to the conditions that they evaluate and treat.

I've also added a few novel features that clarify why an ROS question is asked and in what direction the response should lead. These include:

  1. Clicking on the main questions lists the most common disorders associated with that symptom.
  2. Parentheses include symptoms linked to that particular disease.
  3. "Red flag" indicates symptoms that are particularly worrisome for a serious illness.
  4. Where possible, I've bundled the diagnostic possibilities into clinically logical groupings (e.g. acute/chronic, painful/painless, upper/lower, etc).

I would like to highlight several important limitations:

  1. The list of possible diagnoses is not meant to be exhaustive. No patient responses are pathognomonic.
  2. The symptoms in parentheses represent a partial listing of those most commonly associated w/a particular disorder. They are based on general experience, not discrete evidence.
  3. The disease categorizations reflect rough groupings. There are many exceptions. For example, disorders listed in the "acute" section may have chronic presentations, those described as "upper abdominal" may present w/thoracic symptoms, etc.
