Gérontopôle AURA leads with his partner Sigvaris a large study about the compression in institutions and at patient's homes. Indeed, through 3 studies, the mains goals are to identify the facilities and difficulties about the use of the actual tools. The final aim is to propose a future compression device wich could be adapted and that responds to the needs of users and the realities of the field. First study: Construction of a representative morphological database of people who are 60 years old and older. Indeed, the actually sizing tables are not specifics so not adapted to the morphology of the wearer. This can have an impact on the effectiveness of the treatment and the comfort of the patient. Second study: Have a deep comprehension about the pathway of the compression stockings and bandage in public and private establishment specifically retirements homes for dependant elderly people and hospital. The objectives are to understand and identify the role of health professionals from prescription to implementation to the compressive tools and have their feeds backs. Moreover, the goal is to collect the uses and constraints related to compression systems and to identify the possible improvements, needs and hindrances in link with compressions products. Third study: Study of acceptability of a new adjustable compression solution for venous ulcers. The main goal is to understand the needs and expectations by the users and to know if a new adjustable compression system could be accepted by them. For that, it's important to have a feed back about the use of the compression by the caregivers, medical staff and patients and evaluate the comfort about the use of the compression at patient's home and in institutions. Getting their advices, opinions are necessary too.
