Compression therapy occupies a key place in the complex treatment and prevention of chronic venous insufficiency of the lower extremities. Today the pharmaceutical market of Ukraine is represented by a wide range of compression products. Popular in Ukraine are manufacturers of compression products from the Baltic region, Ukraine, there are also Russian, but leading in quality are Germany, USA, and Italy. A survey of consumers and pharmacy practitioners has been performed. The results obtained indicate that compression products for varicose veins treatment are inferior to medicinal products in sales. The main motive for buying a compression product is a doctor’s prescription. The most popular compression garments are stockings.
commodity analysis, compression products, consumer properties, medical knitwear
Concern for the health of the population is one of the main tasks of our state. Unfortunately, the difficulties associated with the diagnosis and prevention of certain diseases, as well as the treatment of patients, lead to huge losses and become an extremely important socio-economic problem of society. One such dangerous disease is chronic venous insufficiency (CVI), which occurs due to complications of blood flow from the veins of the lower extremities, usually associated with varicose veins, or is a consequence of deep vein thrombosis of the lower extremities (
After the invention of rubber vulcanization, doctors began to use materials that possess elasticity, such as elastic bandages. However, a fundamentally new era in the history of compression therapy has begun when compression knitwear was created (
Compression garments are special clothing containing elastomeric fibers and yarns used to apply substantial mechanical pressure on the surface of needed body zones for stabilizing, compressing, and supporting underlying tissues (
The main purpose of this work was to study the consumer properties of compression products, to study the market and the range parameters of the compression knitted medical products, to which increased requirements during operation are put.
Frequency and descriptive analysis. In the course of the work, the classes and types of compression products have been studied, the market of products that can create the effect of compression on the human body has been analyzed.
By definition (
The medical garment has a very wide range of applications. The variety of medical elastic fixing and compression products is quite large. According to State Standard P 51219-98 (1998), they are divided into five groups: elastic bands, elastic bandages, bandages for fixing joints, compression garments, highly elastic compression hosiery (
The term “compression products” is used in medicine to refer to products that can create a compression effect on the human body. According to State Standard P 51219-98 (1998) and State Standard P58236-2018 (2018) compression is a process that creates a physical effect (pressure) on human organs and tissues through an elastic product (
Each compression class is a dosed pressure on the venous walls of a certain part of the human body, i.e., it is a characteristic of the compression (pressure) degree provided by the elastic product on the patient’s body. Most often, manufacturers use the German standard RAL-GZ 387/1, which sets the pressure in the ankle and its distribution along the product.
The group of compression medical devices has several requirements set to, the compliance of which is mandatory to obtain the desired therapeutic effect, such as the correct physiological distribution of pressure, shape resistance, wear resistance, and stability in different conditions of use. (
Today on the market of Ukraine a large number of various models is presented. They differ in external parameters, composition, and, of course, class. As for the external parameters, it is possible to choose different densities and colors of the product. The products include various types of cotton and nylon fibers, a certain percentage of lycra, as well as microfiber.
By purpose, compression stockings are divided into classes: class 1 – pressure up to 23 mmHg. – for the prevention and at initial signs of varicose veins; class 2 – pressure up to 33 mm mercury – in the middle stage of varicose veins and thrombophlebitis; class 3 – pressure up to 45 mm Hg. – for patients with severe venous insufficiency; class 4 – pressure above 45 mm Hg. – to restore lymph flow. There is also preventive compression knitwear, with pressure under 18 mmHg. This value may vary depending on the manufacturer. To choose the right type, a doctor’s recommendation must be followed. And he prescribes not the density of stockings, but their class. The product packaging must contain a transcript of classes by density. This will help to choose the right pair.
The difference between compression models and classic ones is that the pressure on the limbs is from bottom to top, not the opposite. The shins are subjected to maximum compression, and the thigh has about 40% pressure. It is also important to know that the end of the product must be above the affected area by 15–20 centimeters. The lower the affected area is located, the more difficult it is to ensure proper blood flow, respectively, the more effort is required. Compression stockings’ height can be up to the middle of the thigh or the entire thigh. There are also summer models with an open toe.
It has been found that today the pharmaceutical market of Ukraine is represented by a wide range of compression products. Of 38 types of compression products stockings are 15 types (39%), knee-socks are 7 (18%) and tights are 6 (16%) (Fig.
To date, the pharmaceutical market has a very large number of companies that manufacture compression knitwear (Table
Company name | Country | Composition | |
---|---|---|---|
1. | TONUS ELAST | Latvia | Polyamide – 80%; |
Lycra – 20%. | |||
2. | Mediven (Medi) | Germany | • elastane – 31%, |
• polyamide – 69%. | |||
3. | Relaxsan | Italy | composition of microfiber – elastane – 21%, polyamide – 79%; |
4. | Soloventex | Ukraine | Polyamide, elastane, cotton. |
5. | Veinax | France | polyamide – 70%, elastane – 30% |
6. | Tiana | Italy | polyamide – 73%, lycra – 27%. |
7. | VENOTEKS | USA | Nylon – 75%, elastane – 25% |
Among the world’s best manufacturers of compression knee socks, stockings and tights are the following companies: (
According to the results of the comparison, it is possible to draw the following conclusion. In their products, manufacturers adhere to the required composition and in almost all products it is the same. But, depending on the class of compression stockings, the material ratio may vary.
At the next stage of our research, a survey of consumers was conducted. 100 consumers were interviewed, but some of the questionnaires were rejected, so 87 questionnaires were selected for research. The vast majority of respondents are people aged 18–30 with unfinished higher education.
At this stage of the study, the motivation to buy compression products has been studied.
The results of the survey in Fig.
The next step in the study was to determine the sales of compression products compared to pharmaceutical products.
A survey was conducted for specialists in the pharmaceutical industry, which were presented by the following groups: interns, work experience of up to 1 year; specialists, work experience 1–5 years; specialists, work experience 5–10 years; Specialists with more than 10 years of work experience. A total of 78 respondents have been interviewed. Part of the questionnaires was rejected due to incompleteness. Therefore, 73 questionnaires were used for further analysis.
The results of the survey of specialists have shown that compression products account for 20% of the tools for the prevention and treatment of varicose veins, while pharmaceuticals account for 80%. The survey also showed that consumers prefer drugs in solid dosage form 82%, as compared to semisolid dosage forms 18%. Such a result may be due to the relatively high cost of compression products compared to pharmaceutical products for varicose veins and the lack of reimbursement of medical devices in Ukraine.
The collection of personal information was carried out considering ethical requirements when working with people under the Helsinki Declaration (World Medical Association Declaration of Helsinki, Ethical Principles for Medical Research Involving Human Subjects). All study participants agreed to an anonymous questionnaire. The conclusion about statistical hypotheses was made at the level of significance p ≤ 0.05. The survey was attended by people from different networks and private enterprises of Ukraine, from the following cities: Kharkiv, Poltava, Kyiv, Dnipro, Chernihiv, Lviv.
