What are the best management strategies for a patient with poor wound healing?

Management Strategies for Poor Wound Healing

An interdisciplinary care team approach with comprehensive wound bed preparation, optimization of host factors, and appropriate dressing selection is the most effective strategy for managing patients with poor wound healing. 1

Identifying and Addressing Underlying Causes

Host Factors Optimization

• Glycemic control: Optimize diabetes management (target individualized HbA1c goals) 1, 2
• Smoking cessation: Critical for improving tissue oxygenation and microcirculation 1
• Vascular assessment:
  • Evaluate peripheral pulses and consider non-invasive vascular studies (ABI, toe pressures)
  • Consider revascularization for patients with critical limb ischemia 1, 2
• Medication review: Reduce or modify medications that impair healing when possible:
  • Corticosteroids
  • Immunomodulators (TNF-α inhibitors)
  • Chemotherapy agents 1

Nutritional Support

• Caloric and protein requirements:
  • For malnourished adults with pressure injuries: 30-35 kcal/kg/day and 1.25-1.5g protein/kg/day 1
  • Adjust based on weight changes and wound healing progress
• Micronutrient supplementation:
  • B vitamins (B6, B12)
  • Folate
  • Zinc
  • Arginine
  • Glutamate
  • Vitamin C and D 1, 3, 4
• Adequate hydration: Improves microvascular perfusion 1

Wound Bed Preparation (T.I.M.E. Framework)

Tissue Management

• Debridement: Remove necrotic tissue, debris, and biofilm using:
  • Sharp debridement (most effective for eschar and necrotic tissue)
  • Enzymatic debridement
  • Autolytic debridement
  • Biological debridement 1, 2

Infection/Inflammation Control

• Biofilm management: Present in 90% of chronic wounds 1
  • Antimicrobial dressings containing:
    • Iodine
    • Medical-grade honey
    • Silver
    • EDTA
  • Collagen matrix dressings to reduce protease activity 1
• Systemic antibiotics: Only indicated for acute wound infections, not for biofilm management 1
• Deep tissue cultures: Obtain during debridement for targeted antimicrobial therapy 2

Moisture Balance

• Appropriate dressing selection based on wound characteristics:
  • Hydrogels for necrotic wounds
  • Alginates or foams for exudative wounds
  • Films or hydrocolloids for dry wounds 2
• Negative pressure wound therapy (NPWT): Particularly effective after revascularization and minor amputation 1, 2

Edge Advancement

• Offloading: Critical for wounds on weight-bearing surfaces 1, 2
• Pressure redistribution: Use appropriate support surfaces in all settings (sleeping, seating, transportation) 1

Advanced Therapies for Recalcitrant Wounds

Adjunctive Therapies

• Intermittent pneumatic compression devices: May provide modest benefit for patients with critical limb ischemia who are ineligible for revascularization 1
• Hyperbaric oxygen therapy: Evidence is inconclusive; may be considered in selected cases 1
• Cellular and tissue-based products: Consider for wounds that fail to progress with standard care 5

Surgical Options

• Revascularization: Essential for wounds with underlying vascular insufficiency 1
• Skin grafts: Consider after wound bed is optimized and patient is stabilized 1

Interdisciplinary Team Approach

• Team composition:

  • Wound care specialists
  • Vascular surgeons
  • Infectious disease specialists
  • Endocrinologists
  • Nutritionists
  • Physical therapists 1, 2

• Coordinated care: Structured team approach rather than ad hoc referrals 1

Common Pitfalls and Caveats

• Biofilm recognition: Often overlooked but present in 90% of chronic wounds; requires aggressive debridement and antimicrobial strategies 1
• Overuse of antibiotics: Systemic antibiotics should be reserved for acute infections, not for biofilm management or chronic colonization 1
• Inadequate offloading: Failure to properly offload pressure points will prevent healing despite optimal care 2
• Neglecting vascular status: Revascularization should be prioritized when indicated 1
• Nutritional deficiencies: Often underestimated but critical for healing; comprehensive nutritional assessment and intervention is essential 3, 4

By systematically addressing these factors with an interdisciplinary approach, even challenging wounds can achieve complete healing, reducing the risk of complications and improving patient outcomes.
