Hard-to-heal wounds, biofilm and wound healing: an intricate interrelationship.

摘要

Hard-to-heal wounds are a major public health problem that incur high economic costs. A major source of morbidity, they can have an overwhelming impact on patients, caregivers and society. In contrast to acute wound healing, which follows an 'orderly and timely reparative process', the healing of hard-to-heal wounds is delayed because the usual biological progression is interrupted. This article discusses hard-to-heal wounds, the impact they have on patients and healthcare systems, and how biofilms and other factors affect the wound-healing process. Controlling and preventing infection is of utmost importance for normal wound healing. Rational use of anti-infectious agents is crucial and is particularly relevant in the context of rising healthcare costs. Knowledge of the complex relationship between hard-to-heal wounds, biofilm formation and wound healing is vital for efficient management of hard-to-heal wounds.
