Introduction: Under normal conditions, valves within the venous system direct blood from the superficial into the deep system, which return the blood back towards the heart. A host of illnesses and disease states can affect these anatomic functions contributing to the development of venous insufficiency. Chronic venous insufficiency leads to pooling of the blood and fluid in the legs. Patients may first experience edema in the lower extremities. Over time, trophic changes in the tissues appear and eventually skin necrosis and ulcerations occur. Daily use of compression garments is recommended to treat lower extremity edema and reduce the risk of ulcer formation, but the use of traditional compression garments in this patient population can be a challenge.Methods:The purpose of this study was to assess the usability of an innovative compression garment (AWCS) indicated for use in patients with venous insufficiency, lower extremity edema or a history of venous leg ulcers. The study was conducted with consented subjects over the age of 18. The evaluation included points of interaction between the user and the device, including all elements of the device with which the user interacts. All users were asked to populate a 3 Part questionnaire to assess the subject’s feedback of their current compression garment, feedback after utilizing the AWCS garment and feedback comparing their current compression garment to the AWCS garment.Results:The final usability study data analysis found that the AWCS ranked significantly higher than traditional compression wear. The AWCS garment was found to be easier to apply compared to SOC compression garments. Furthermore, the increased ease of self-application of the AWCS reduced patient exertion and decreased time spent on edema management supporting an increased patient QOL.Discussion: Adherence to traditional compression garments can be limited due to difficulty with donning the devices. Increased age, limited range of motion, decreased dexterity, poor eyesight, decreased strength and agility are common reasons patients have difficulty adhering to compression garment use. The AWCS was found to be very user friendly thus it has the potential to improve patient outcomes in this at-risk patient population.References:
