What are some of the differences between the HPI and the ROS?

What will be an ideal response?

The answer should include any (or all) of the following:
? The HPI addresses the patient's current experience of the chief complaint, while the ROS addresses the patient's experience of health prior to i) the onset of the CC, and ii) the visit with the clinician.
? The HPI elements are considered "empathy elements", describing the patient's personal experience, while the ROS elements specifically address the state of the patient's overall health prior to the visit.
? The HPI does not specifically address the CC in terms of organ systems, while the ROS is a categorical review of the patient's health in terms of organ systems.
? The HPI must be collected, gathered, or recorded by the performing physician, while the ROS may be verbally collected by any clinical member of the staff, or gathered by requesting the patient complete a pre-printed questionnaire.
