Clinical Trial 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.

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.

Intervention

Procedure:
• SPA 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

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Changes from baseline in CIVIQ-2 score at 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).	Baseline (D1) and final (6 months)
Secondary	Changes from baseline in Quality of Life at 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).	Baseline (D1) and final (6 months)
Secondary	Changes from baseline in 0-100 VAS leg pain related to chronic venous insufficiency at 6 months	Pain intensity is measured using a 0 (no pain)-100 (Worse pain) Visual Analogic Scale (VAS).	Baseline (D1) and final (6 months)
Secondary	Frequency of adverse events throughout the study	Adverse events are described using MedDRA and each event frequency is calculated.	From inclusion to the final visit at 6 months]
Secondary	Participants' satisfaction with the spa therapy program at the end of the program and at 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")	20 days and 6 months
Secondary	Medical-economic impact of the spa therapy program at 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)	6 months
