An Overview on Wound Bed Preparation and the TIME Framework

For a proper wound assessment, “Wound Bed Preparation” has become a standard model which allows physicians to identify and breakdown local barriers for healing the injury. It’s a complex process which can be impacted by an array of significant factors. In addition, it usually progresses through various phases including Cell Proliferation & Repair, Coagulation & Homeostasis, Epithelization and Remodeling of Scar Tissue, Inflammation, and more.

In this treatment method, TIME Framework is an imperative tool employed to assist professional surgeons with the management of patients’ wounds throughout the care cycle. In simpler terms, it was developed to address pathophysiological abnormalities of injuries by optimizing conditions for healing. It’s achieved by correcting the abnormalities that impair healing, reducing the edema & exudate as well as bacteria burden.

The Time Framework

The 4 components of the “Wound Bed Preparation” care cycle which comprise the Time model include Tissue Management, Infection or Inflammation, Moisture Balance, and Wound Edge.

  1. Tissue Management: It’s one of the major components which helps identify viably as well as non-viable tissue. In this, the surgeon searches for and removes Necrotic or Compromised Tissue in order to ensure a viable wound base. Indeed, debridement is generally crucial only once, particularly for acute wounds. Additionally, this treatment modality may be repeated several times when it comes to chronic injuries.
  2. Infection or Inflammation: This component of Wound Bed Preparation is known to “Impair Healing”. To optimize the injury conditions, controlling the bioburden or the presence & concentration of fungal and bacterial organisms is extremely important.
  3. Moisture Balance: You may know or not, too little or too much moisture can hinder the process of healing in various ways. And, thus, creating a balanced moisture level is pivotal in order to promote re-epithelialization.
  4. Edge of Wound Advancement (Epithelial Advancement): chronic wounds don’t progress sequentially through several healing phases. Assessing an injury’s tendency to advance can assist you with treatment methods. And, the procedure you opt for should work to promote epithelialization and attain a healthy periwound area.

To sum up, chronic injuries, and even complex acute wounds, are quite challenging to treat. This is because they may have a multitude of issues that can impair healing. To get effective treatment, the injury should be appropriately assessed.
