The ANCA Vasculitis Questionnaire (AAV-PRO©)

Patients with ANCA-associated vasculitis have inflammation in the small vessels that impact a range of organs and Investigators understand that patients may suffer ongoing disease activity, as well as side effects from the treatments. Assessing patients quality of life can be an important tool for conducting clinical trials for new treatments and medications. 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. A small group of Investigators and Patient-Partners developed this survey for people with ANCA-associated vasculitis (the AAV-PRO). Investigators will invite patients with AAV to complete the questionnaire they have designed, called the AAV-PRO. By analysing how people fill in the questionnaire, Investigators will be able to find out how well the questions work, and whether they need to ask all of them.
