The current state of care for patients with hard-to-heal wounds poses serious challenges for the healthcare system. Although there are no relevant statistics, it is estimated that up to one million Poles suffer from chronic wounds, which have enormous health, social, and economic consequences. Arterial or venous leg ulcers, diabetic foot ulcers, pressure ulcers and cancer ulcers, surgical site infections and complications of healing after surgery are the main types of wounds responsible for the enormous physical and mental suffering of patients.
