Wound Bed Preparation: Applying the Principles of TIME

Martha Kelso, RN, HBOT

Preparing a wound for healing is key to ensure chronic wounds convert to healing wounds. Using the TIME mnemonic assists clinicians and bedside nurses to think critically when making decisions on treatment options. This webinar uses wound photographs paired with terminology to interpret what the wound is communicating. After reviewing the photos, various treatment options will be discussed.


The TIME Model of Wound Bed Preparation

Effective wound bed preparation is a cornerstone of modern wound care by helping to promote rapid healing and minimize the risk of complications such as infection. This guide provides wound care professionals with clear foundational knowledge of the evidence-based TIME framework for wound bed preparation, as well as the latest information on the principles and benefits of preparing the wound bed for optimal healing outcomes.

Terms to know: Wound Bed Preparation

Bacterial load/burden: Presence of bacterial pathogens in an open wound contributing to wound chronicity and persistence of inflammatory cycle. There are several points along the spectrum of bacterial presence in chronic wounds: contamination, colonization, critical colonization, infection, and sepsis.

Debridement: The procedural act of removing non-viable tissue, along with any debris, from the wound. There are multiple debridement modalities, some of which are selective for non-viable tissue and some which are non-selective (viable tissue is removed as well, e.g., mechanical debridement with gauze sponges): sharp (conservative or excisional/surgical), mechanical, autolytic, enzymatic/chemical, and biological.


Restoring the Wound Base: The Role of Tissue Management

Successful utilization of the TIME model for wound bed preparation requires a working knowledge of chronic wound tissue types. In addition, building on this foundational knowledge is the development of…

The Science of Healing: Wound Bed Preparation Actions and Effects

For wound healing to occur, a complex, well-defined cascade of events must take place in the body’s natural host processes. When this cascade of events is disturbed, a wound can fall into a state of non-healing…
