Based on final 2011-12 data, first published on 15 October 2013.
The Aberdeen Varicose Vein Questionnaire ('AVVQ') combines into a single score a patient's answers to a number of health questions of particular relevance to varicose veins.
The questionnaire has a section in which the patients can indicate diagrammatically the distribution of their varicose veins. There are also questions relating to the amount of pain experienced; ankle swelling; use of support stockings; interference with social and domestic activities and the cosmetic aspects of varicose veins.
The score is a value from 0 to 100, where 0 is 'best' and 100 is 'worst'.
