The wound-healing process is not only complex but fragile, and it is susceptible to interruption or failure leading to the formation of non-healing chronic wounds. Factors that contribute to non-healing chronic wounds are diabetes , venous or arterial disease , infection, and metabolic deficiencies of old age.
Wound assessment is a vital first step in the precision management process. The purpose of wound assessment is: To identify: the origin of the wound, the effects of the wound on the individual, the effects of the individual on the wound. To determine: if healing is taking place, the most appropriate management of the wound. To gather data:
A week after the injury, the edges of the wound are pulled together by contraction. Contraction is an important part of the healing process when damage has been extensive, and involves shrinking in size of underlying contractile connective tissue, which brings the wound margins toward one another.

Research into hormones and wound healing has shown estrogen to speed wound healing in elderly humans and in animals that have had their ovaries removed, possibly by preventing excess neutrophils from entering the wound and releasing elastase. [26] Thus the use of estrogen is a future possibility for treating chronic wounds.
In biology, hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). It is the first stage of wound healing. Hemostasis involves three major steps: vasoconstriction; temporary blockage of a hole in a damaged blood vessel by a platelet plug
Wound assessment is a holistic process that considers the patient's current state of health, the factors that may impede wound healing, and the cause, duration and state of the wound. [6] As such, this process is applicable to any wound.
For example, an RFID tag attached to an automobile during production can be used to track its progress through the assembly line, [citation needed] RFID-tagged pharmaceuticals can be tracked through warehouses, [citation needed] and implanting RFID microchips in livestock and pets enables positive identification of animals.

Negative pressure wound therapy device. Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess wound exudate and to promote healing in acute or chronic wounds and second- and third-degree burns.
