Quality of life can be measured by questionnaires called "patient reported outcome measures" (PROM). What is a patient-reported outcome? Patient-reported outcomes, or PROs, are patients' feedback on what they are feeling or what they are able to do as participants are dealing with a chronic disease . Patient-reported outcomes are important because they provide doctors and researchers information about patients' quality of life. Questionnaires can be designed to measure specific PROs that are of specific importance to a disease and can provide much needed information on evaluating the effectiveness of health care. The aim of this survey is to develop a disease specific patient reported outcome measure, or PROM, for patients with AAV.
