WOUND CARE CHALLENGES
Patient noncompliance, bioburden and biofilm, excess MMPs, and ECM degradation all present barriers to wounds healing correctly.
PATIENT NONCOMPLIANCE
Inability and/or unwillingness to adhere to treatment plans for chronic wounds is a major barrier to healing.
- Many patients with lower-extremity chronic wounds are unable to change their own dressings1
- Patients with chronic wounds fear touching their own wounds and prefer that their doctor or nurse exclusively control their care1,2
- When treatments do force patients to change their own primary dressings, wounds can be exposed to bacteria in the home that can lead to contamination
BIOBURDEN & BIOFILM
- Acute and chronic wounds are susceptible to infection and biofilm development; as a result, early intervention to control bacterial bioburden is essential3
- Excessive bioburden and biofilm trigger a continuous inflammatory response and lead to increased proteases (eg, MMPs) that attack granulation tissue and stall wound healing4
EXCESS MMPs
- In healthy wound healing, proteases such as MMPs play a critical role by helping to remove damaged ECM and bacteria5,6
- In nonhealing wounds, the bacteria in biofilm generate excess and imbalanced MMPs that can5,6:
- Break down the ECM
- Degrade healing proteins
- Prolong the inflammatory phase of healing
ECM DEGRADATION
- ECM serves as a structural scaffold for proteins and cell proliferation to support healing7
- ECM degradation prevents the formation of the scaffold needed for cell migration and prevents proper formation of the ECM and granulation tissue7
ECM=extracellular matrix
MMP=matrix metalloproteinases
