The PIVOT system's Review of Systems screen:

The Review of Systems section is catalogued by organ systems, as commonly seen in many electronic medical record systems. Within each organ system, users can ask a myriad of questions to the patient. Because a patient's physician visit period is often very time-limited, it is important to perform a focused review of systems to address pertinent symptoms. While performing a review of systems, users need to decide whether each piece of information is diagnostically critical by clicking on the corresponding "Critical" button.
