Chronic, complex, or problem wounds are skin ulcers or sores that do not heal without special treatment. Wounds that fail to heal in three months are usually considered chronic. Some take years to heal or never do.
Represent a significant and growing challenge to our healthcare system. The incidence and prevalence of these wounds are increasing in the population resulting in growing utilization of healthcare resources and dollars expended.
Common chronic wounds include venous ulcers (leg), arterial ulcers (foot), diabetic ulcers (leg and foot), and pressure ulcers (bedsores on elbows, back, ankles, hips, and heels).
Require a healthy, oxygenated wound bed to heal.
A lack of sufficient oxygen (hypoxia) in the wound bed slows or stops the normal healing process. Healing is notably difficult in patients with poor general or circulatory health.
Diabetes, in particular, may inhibit wound healing and increase the risk of infection and amputation.
Wounds resulting from trauma, surgery, burns, skin grafting, and adiation therapy may also become problem wounds.
Chronic wounds are especially prone to serious bacterial infections that threaten life and limb.
