Randomized Controlled Trial Multicenter Study
The VVSymQ® instrument: Use of a new patient-reported outcome measure for assessment of varicose vein symptoms.
No existing patient-reported outcome instrument focuses solely on assessment of varicose veins symptoms that are bothersome to patients. ⋯ The VVSymQ® instrument is a reliable, valid instrument responsive to measuring change in the patient experience of varicose vein symptoms pre- and post-intervention, and is uniquely focused on patient-reported symptoms compared with other widely used questionnaires completed by clinicians.
