3.2.1 The Discover phase
It consisted of Interviews with six patients with keloid, who were using conventional pressure therapy (elastic bands or garments, foams and silicone sheets). The patients were from the Outpatient Clinic of Pathological Scars of the Unifesp, Plastic Surgery Division. They were questioned in order to identify the main problems, needs and suggestions to improve the compression therapy. They were asked: a) Regarding the individual understanding of the use of pressure therapy for their treatment; b) The acquisition of products and materials (stores and values) to carry out the therapy; c) As for the routine of use (hours per day), comfort and practicality of the therapy. The conversations were individual, lasting about 15 to 20 minutes.
A Desk Research was also carried out on the acquisition of information about devices and garment available on the market used for compression therapy in scars. The databases used were Google and Medline. The keywords used were similar to those referred to in the main search. Finally, a scenario was elaborated to simulate the step-by-step performed by the patient with keloid in the adequate accomplishment of the therapy. It was sought to understand and experience all the process involved, from the purchase of the products, materials and garments used until the application of the compressive therapy. In addition, it was used to verify the routine of use and its practicality.
