Clinical measures of health outcomes, such as x rays and lab tests, may have little relevance to the day-to-day functioning of patients with chronic diseases. Often, the best way patients can judge the effectiveness of treatments is by changes in their symptoms. This feedback or data is called Patient Reported Outcomes.
