The World Health Organization and United Nations issued a warning statement on the world’s health in September 2011 on hard to heal wounds as 2-3% of world population is expected to suffer severe wound in life. Estimated cost of treating chronic wounds is between 2-3% of annual healthcare budgets (treatments and hospitalization). Essential part of the wound care treatment (after removal of devitalized tissue) is the use of dressings to promote autolysis and reduce microbial presence.
Most advanced solutions in market currently are collagen dressings made of native collagen that facilitates healing of the wound providing exogenous collagen to the wound. Nonetheless, this solution has several problems: application and removal problems, fixed shapes, limited draining capacity. Additionally, the high price of the product (1-5€/cm²) makes it expensive product and high cost for public care system.
