The goal of this American College of Phlebology Patient Reported Outcome Venous Registry analysis was to examine the clinical efficacy of compression stockings using short-form 6D questionnaire (SF-6D).SF-6D scores were modeled over time using linear mixed effects model. Changes of SF-6D score from baseline to the last encounter were examined using a paired t-test. Analysis of variance was used to compare changes from baseline in SF-6D scores between C classifications. All analyses were conducted using SAS software, version 9.4 (SAS Institute, Cary NC).Baseline mean SF-6D score was 0.83 and at follow-up, 0.85. Mean SF-6D change was +0.02 points (P = .001) over an average time period of 5.5 months. Patients’ SF-6D scores were estimated to increase by +0.03 points (P = .005) per year of usage of compression stockings. SF-6D score changes across C classifications did not demonstrate significant differences (P = .265).There was an improvement of SF-6D score in the registry participants who used circular knit compression stockings.
