Comparison of disease-specific quality of life tools in patients with chronic venous disease.

This work was presented as a poster in the American Venous Forum 25th Annual Meeting; 28 February 2013; Phoenix, Arizona, USA. Quality of life (QoL) is an important outcome measure in the treatment for chronic venous disease. The Aberdeen Varicose Vein Questionnaire (AVVQ) and the ChronIc Venous Insufficiency quality of life Questionnaire (CIVIQ-14) are two validated disease-specific QoL questionnaires in current use. The aim of this study is to evaluate the relationship between the AVVQ and the CIVIQ-14 to enable better comparison between studies and to compare these disease-specific QoL tools with generic QoL and clinician-driven tools. Adults attending our institution for management of their varicose veins completed the AVVQ, CIVIQ-14 and EuroQol-5D (EQ-5D). Clinical data, CEAP classification and the Venous Clinical Severity Score (VCSS) were collected. The relationship between the AVVQ and CIVIQ-14 scores was analysed using Spearman's correlation. The AVVQ and CIVIQ-14 scores were also analysed with a generic QoL tool (EQ-5D) and a clinician-driven tool, the VCSS. One hundred patients, mean age 57.5 (44 males; 56 females), participated in the study. The median AVVQ score was 21.9 (range 0-74) and the median CIVIQ-14 score was 30 (range 0-89). A strong correlation was demonstrated between the AVVQ and CIVIQ-14 scores (r = 0.8; p < 0.0001). Strong correlation was maintained for patients with C1-3 disease (r = 0.7; p < 0.0001) and C4-6 disease (r = 0.8; p < 0.0001). The VCSS correlated strongly with the AVVQ and CIVIQ-14 scores (r = 0.7; p < 0.0001 and r = 0.7; p < 0.0001, respectively). Both the AVVQ and CIVIQ-14 scores correlated well with the EQ-5D score (r = -0.5; p < 0.0001 and r = -0.7; p < 0.0001, respectively). This study demonstrates that there is good correlation between two widely used varicose vein specific QoL tools (AVVQ and CIVIQ-14) across the whole spectrum of disease severity. Strong correlation exists between these disease-specific QoL tools and generic and clinician-driven tools. Our findings confirm valid comparisons between studies using either disease-specific QoL tool.

Validation of Venous Clinical Severity Score (VCSS) with other venous severity assessment tools from the American Venous Forum, National Venous Screening Program.

Several standard venous assessment tools have been used as independent determinants of venous disease severity, but correlation between these instruments as a global venous screening tool has not been tested. The scope of this study is to assess the validity of Venous Clinical Severity Scoring (VCSS) and its integration with other venous assessment tools as a global venous screening instrument. The American Venous Forum (AVF), National Venous Screening Program (NVSP) data registry from 2007 to 2009 was queried for participants with complete datasets, including CEAP clinical staging, VCSS, modified Chronic Venous Insufficiency Quality of Life (CIVIQ) assessment, and venous ultrasound results. Statistical correlation trends were analyzed using Spearman's rank coefficient as related to VCSS. Five thousand eight hundred fourteen limbs in 2,907 participants were screened and included CEAP clinical stage C0: 26%; C1: 33%; C2: 24%; C3: 9%; C4: 7%; C5: 0.5%; C6: 0.2% (mean, 1.41 ± 1.22). VCSS mean score distribution (range, 0-3) for the entire cohort included: pain 1.01 ± 0.80, varicose veins 0.61 ± 0.84, edema 0.61 ± 0.81, pigmentation 0.15 ± 0.47, inflammation 0.07 ± 0.33, induration 0.04 ± 0.27, ulcer number 0.004 ± 0.081, ulcer size 0.007 ± 0.112, ulcer duration 0.007 ± 0.134, and compression 0.30 ± 0.81. Overall correlation between CEAP and VCSS was moderately strong (r(s) = 0.49; P < .0001), with highest correlation for attributes reflecting more advanced disease, including varicose vein (r(s) = 0.51; P < .0001), pigmentation (r(s) = 0.39; P < .0001), inflammation (r(s) = 0.28; P < .0001), induration (r(s) = 0.22; P < .0001), and edema (r(s) = 0.21; P < .0001). Based on the modified CIVIQ assessment, overall mean score for each general category included: Quality of Life (QoL)-Pain 6.04 ± 3.12 (range, 3-15), QoL-Functional 9.90 ± 5.32 (range, 5-25), and QoL-Social 5.41 ± 3.09 (range, 3-15). Overall correlation between CIVIQ and VCSS was moderately strong (r(s) = 0.43; P < .0001), with the highest correlation noted for pain (r(s) = 0.55; P < .0001) and edema (r(s) = 0.30; P < .0001). Based on screening venous ultrasound results, 38.1% of limbs had reflux and 1.5% obstruction in the femoral, saphenous, or popliteal vein segments. Correlation between overall venous ultrasound findings (reflux + obstruction) and VCSS was slightly positive (r(s) = 0.23; P < .0001) but was highest for varicose vein (r(s) = 0.32; P < .0001) and showed no correlation to swelling (r(s) = 0.06; P < .0001) and pain (r(s) = 0.003; P = .7947). While there is correlation between VCSS, CEAP, modified CIVIQ, and venous ultrasound findings, subgroup analysis indicates that this correlation is driven by different components of VCSS compared with the other venous assessment tools. This observation may reflect that VCSS has more global application in determining overall severity of venous disease, while at the same time highlighting the strengths of the other venous assessment tools.

Chronic venous disease in Spain: doctor-patient correlation.

The present study aimed to demonstrate how the quality of life (QoL) perceived by patients with chronic venous disease (CVD) is correlated with the severity of their disease objectively assessed by primary care physician. A total of 1560 patients with CVD were evaluated using four measurement instruments: CEAP clinical classification, Venous Clinical Severity Score (VCSS), SF-12 Health Survey and Chronic Lower Limb Venous Insufficiency Questionnaire (CIVIQ-20). Statistical correlations between these tools were analysed using Spearman's coefficient. Patients were distributed in C0, 58 (3.7%); C1, 243 (15.6%); C2, 328 (21.0%); C3, 357 (22.9%); C4, 368 (23.6%); C5, 136 (8.7%); and C6, 70 (4.5%). The VCSS score for the whole cohort was 0.89 ± 0.53. The correlation between CEAP and VCSS was moderately strong (r = 0.69). The overall QoL scores measured by SF and CIVIQ were 56.84 ± 19.63 and 65.11 ± 14.35, respectively. The correlation between the two QoL questionnaires was very strong (r = 0.81). The correlations of the SF and CIVIQ with the VCSS were moderately strong (r = -0.47 and -0.48). The correlations between QoL questionnaires and CEAP were moderate and lower than those with VSCC. While there is correlation between VCSS, CEAP, modified CIVIQ and venous ultrasound findings, subgroup analysis indicates that this correlation is driven by different components of VCSS compared with the other venous assessment tools. Patients' opinions about their disease are correlated with those assessed by primary care physicians.

Great saphenous vein diameter does not correlate with worsening quality of life scores in patients with great saphenous vein incompetence.

Previous studies have correlated increasing great saphenous vein (GSV) diameter with increasing CEAP clinical classification. Some insurance carriers are currently using specific GSV diameters to determine coverage for treatment of axial venous insufficiency. The aim of this study was to investigate the correlation of patient quality of life (QOL) measures with GSV diameters in varicose vein patients with GSV reflux. Data were collected from the records of 91 patients prospectively enrolled in two varicose vein trials. The patients had symptomatic varicose veins with saphenofemoral junction and proximal GSV reflux. Maximum GSV diameter was measured on duplex ultrasound imaging, with the patient standing, within 5 cm of the saphenofemoral junction. Chronic Venous Insufficiency Questionnaire 2 (CIVIQ-2; Servier, Neuilly-sur-Seine, France), Venous Insufficiency Epidemiological and Economic Study (VEINES) Symptom (Sym) and QOL assessments, and the Venous Clinical Severity Score (VCSS) assessment were completed before treatment of GSV insufficiency. Demographic information, patient weight, height, and body mass index were collected. Correlations between pairs of data were done using Pearson product-moment and Spearman correlation coefficients. The 91 study patients (19 men, 72 women) were a mean age of 45 years (range, 18-65 years). The mean GSV diameter was 6.7 mm (range, 2.2-14.1 mm). The mean VCSS score was 7.8 (range, 3-12). There was a weak correlation between increasing GSV diameter and VCSS (r=0.23; P=.03) and no correlation between GSV diameter and the CIVIQ-2 score (r=0.01), VEINES-QOL (r=-0.07), and VEINES-Sym (r=-0.1). GSV diameter is a poor surrogate marker for assessing the effect of varicose veins on a patient's QOL; thus, using GSV diameter as a sole criterion for determining medical necessity for the treatment of GSV reflux is inappropriate. Further correlations between QOL measures and duplex-derived objective findings are warranted.
