Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Occlusion of treated vein post-procedure | Immediately post-op | ||
Primary | Change in anatomy of treated vessel | Anatomical Success as measured at each timepoint using ultrasound to ensure occlusion of treated vessel. Recurrence or treatment failure will be defined as a re-opening of a segment > 5cm in length. | 2 weeks, 3 months, 6 months, 12 months post-procedure | |
Secondary | Quality of Life Score using the EQ-5D questionnaire | EQ5D is used to assess quality of life based on Mobility, Self-Care, Usual Activities, Pain/Discomfort and Anxiety, rated at 5 levels: no problems, slight problems, moderate problems, severe problems, unable to perform activity. Inputs from this questionnaire is used to observe for changes in quality of life overtime. The higher the score, the better the quality of life is. | 2 weeks, 3 months, 6 months, 12 months post-procedure | |
Secondary | Quality of Life Score using the Chronic Venous Insufficiency Questionnaire (CIVIQ) | CIVIQ is a questionnaire based on three dimensions - pain, physical and psychological, based on a scale from 1 to 5 (no trouble, slight, moderate, considerable, severe). Based on inputs, Global Index Score (GIS) will be tabulated, ranging for 0 to 100 - the higher the value, the poorer the quality of life. | 2 weeks, 3 months, 6 months, 12 months post-procedure | |
Secondary | Quality of Life score using the Aberdeen Varicose Vein Questionnaire (AVVQ) | To measure health status of varicose veins patients based on symptoms and impact on daily activities. A total score ranging from 0 to 100 will be tabulated, with 100 being worst quality of life. | 2 weeks, 3 months, 6 months, 12 months post-procedure | |
Secondary | Clinical Change using Venous Clinical Severity Score (VCSS) | VCSS evaluates the severity of hallmarks of venous disease - 0 (none), 1 (mild), 2 (moderate), 3 (severe). | 2 weeks, 3 months, 6 months, 12 months post-procedure | |
Secondary | Pain Score | Using a numerical rating scale, which ranges from 0 (no pain) to 10 (severe pain) | First 10 days post-procedure | |
Secondary | Time taken to return to work and normal activities | Recorded 10 days post-procedure | ||
Secondary | Occlusion rates | Duplex ultrasound performed at specific timepoints to ensure that treated vein is occluded | 2 weeks, 3 months, 6 months, 12 months post-procedure | |
Secondary | Patient satisfaction with treatment: survey | A short survey to assess patient satisfaction and if there are any observed improvement in terms of appearance and symptoms post-procedure. Options range from highly unsatisfied to highly satisfied. | 2 weeks, 3 months, 6 months, 12 months post-procedure | |
Secondary | Cost effectiveness of the intervention | to evaluate the cost involved with the procedure performed | 12 months post-procedure |
