Brief summary
The aim of this clinical trial is to assess the efficacy of the balneotherapy program (therapeutic orientation: Phlebology) in terms of chronic venous disease improvement and related quality of life, in patients presented with advanced chronic venous insufficiency (i.e., with C4-C5 of severity classification). The multicenter randomized controlled trial (RCT) Thermes & Veines that aimed at evaluating balneotherapy in patients with advanced chronic venous insufficiency is considered as the reference study. The French National Academy of Medicine encourages the re-use of data of published RCT when available. In this context, the current study is designed as a single-arm prospective study with indirect comparison using propension score. The Control group consists of the 197 patients which were allocated to the Control group of the Thermes & Veines. All patients enrolled in the current study benefit of 18-days of spa treatment with Mineral Water of Royat, and examination with vascular practitioner at enrollment and 6 months after the beginning of spa treatment.
Detailed description
Chronic Vascular Disease (CVD) related quality of life and symptoms, as well as skin trophic changes from baseline are assessed at 6 months. Variations from baseline are compared in Control and Spa treatment groups. The indirect comparison methodology is based on the reuse of individual data from a control group and adjustment after calculating the propensity score.
Interventions
PROCEDURESPA THERAPY
Balneotherapy program Four balneotherapy sessions per day, 6 days a week during 3 weeks The balneotherapy sessions included: * 10- minute walking session in a specially designed pool with tracks in semideep (80 cm) cool (30°C) water (training of muscle pump function under water compression); * 20-minute whirlpool bath session with automatic air or submarine bath if hypodermis (aimed at relaxation and mobilization of the superficial skin volume flow); followed by a 10-minute hydrojet bath (2 sessions) with customized underwater strong massaging jets (mobilization and softening of the sclerotic subcutaneous tissues); * Fresh thermal water compresses at 24°C. The cool temperature of the compresses also has an analgesic and decongestant effect. This treatment is carried out last and is followed by a rest for a total duration of 60 minutes

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes from baseline in CIVIQ-2 score at 6 months | Baseline (D1) and final (6 months) | The Chronic Venous Insufficiency Quality of Life Questionnaire (CIVIQ) is a disease-specific instrument to measure the impact of chronic venous insufficiency on patients' lives. CIVIQ-2 or CIVIQ-20 is a self-administered questionnaire that consists in 20 questions of the CIVIQ result in a global score. All questions have a 5-point response category, with higher scores reflecting more severe impairment. The CIVIQ-20 score ranges from 20 (minimal impact) to 100 (maximal impact). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes from baseline in Quality of Life at 6 months | Baseline (D1) and final (6 months) | Quality of life is measured using the generic EUROQOL (EQ-5D-3L) questionnaire. The EQ-5D-3L descriptive system comprises the following five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 3 levels: no problems, some problems, and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results into a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state). |
| Changes from baseline in 0-100 VAS leg pain related to chronic venous insufficiency at 6 months | Baseline (D1) and final (6 months) | Pain intensity is measured using a 0 (no pain)-100 (Worse pain) Visual Analogic Scale (VAS). |
| Frequency of adverse events throughout the study | From inclusion to the final visit at 6 months] | Adverse events are described using MedDRA and each event frequency is calculated. |
| Participants' satisfaction with the spa therapy program at the end of the program and at 6 months | 20 days and 6 months | Opinion of the patient is measured using a 5-point Likert scale ranging from 1 (not at all satisfied) to 5 (very satisfied) |
| Medical-economic impact of the spa therapy program at 6 months | 6 months | EQ-5D-3L score at 6 months and frequency of adverse events related to chronic venous insufficiency. scores ranges from -0.541 (higher impact of health on quality of life) to 0.982 (lower impact of health on quality of life) |
