Short-form 6D assessment in compression module of the American College of Phlebology Patient Reported Outcome Venous Registry

Abstract

Objective

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).

Method

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).

Results

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).

Conclusion

There was an improvement of SF-6D score in the registry participants who used circular knit compression stockings.
