Any wound that does not show improvement in four weeks or is not totally healed in eight weeks is considered a chronic, non-healing wound. Approximately six million people in the United States (an estimated 2% of the entire population) suffer from chronic, non-healing wounds, and this number is growing steadily. Patients over age 65 are the most frequent chronic wound sufferers. People with diabetes, venous insufficiency and pressure ulcers, nearly 20 million Americans, are among those who most frequently develop chronic wounds. Our network of wound management programs has successfully treated more than 534,000 patients and close to 1.2 million wounds.
