The TIME concept is a support tool for Health Professionals for wound evaluation, taking into account its phases and characteristics, assisting decision making.
T TISSUE MANAGEMENT
Wound bed tissue assessment is essential in the healing process.
The healing process is compromised if non-viable and devitalized tissue is present. Its presence in the wound bed also represents a risk of infection, prolonged inflammatory response, obstruction of wound contraction and a barrier to re-epithelialization.
I INFECTION / INFLAMMANATION CONTROL
Chronic wounds are at increased risk of microbial colonization. Not only due to the amount of time the wound is open, but also due to factors such as hypoxia, history of underlying diseases, poor blood flow, among others.
The inflammatory phase in an acute wound is part of the natural trauma response process by releasing cytokines and growth factors, leads to vasodilation and increased blood flow to the affected area.
M MOISTURE BALANCE
Wound bed moisture balance is essential for the healing process.
Moisture in the wound bed contributes to the autolytic process, and also acts as a transportation of growth during the epithelialization phase. If the wound is kept too dry, it may impede healing and also its contraction.
E E – NON-ADVANCING EDGES / EPITHELIAL EDGE ADVANCEMENT
Wound edges assessment can indicate whether wound contraction and epithelialization are progressing and confirm the effectiveness of the wound care treatment that is used or the need for reassessment. Advanced therapies allow to influence the effect on the edges of the wound, contributing to progression of healing progression.
