Wound Healing Assessment and Treatment
Initial Wound Assessment
- The American College of Physicians recommends using the T.I.M.E. framework for systematic wound bed preparation, combined with standardized assessment tools like NERDS/STONES or MEASURE to guide treatment decisions and monitor healing progression 1, 2
- Measure wound dimensions (length, width, depth) using a sterile blunt metal probe to establish baseline and detect deep tissue involvement including bone or joint communication 3
- Assess surrounding skin for maceration, erythema, edema, induration, and callus formation which indicate infection or excessive moisture 2, 3
- Check for infection signs using NERDS criteria (Nonhealing, Exudate, Red friable tissue, Debris/discoloration, Smell) for superficial infection or STONES criteria (Size increasing, Temperature elevation, Os/probes to bone, New breakdown, Erythema/Edema, Exudate, Smell) for deep infection 1, 2
Treatment Framework: T.I.M.E. Protocol
T - Tissue Debridement
- Perform sharp debridement with scalpel to remove necrotic tissue, slough, biofilm, and surrounding callus at initial assessment and repeat as often as needed 1, 2, 4
- Sharp debridement is superior to enzymatic, autolytic, or biological methods because it is definitive, controllable, and immediately removes bacterial reservoirs 4
I - Infection/Inflammation Control
- Apply topical antimicrobials (iodine, medical-grade honey, silver, EDTA) to infected wounds to destroy microorganisms and prevent biofilm reformation within 24-72 hours 1, 2
- Use collagen matrix dressings to reduce excessive protease activity and inflammation while promoting fibroblast proliferation 1, 2
- Target wound pH of 4-6 using stabilized hypochlorous acid which has germicidal properties without cytotoxicity and promotes fibroblast/keratinocyte migration 1, 2
M - Moisture Control
- Select dressings based on exudate level: hydrogels for dry/necrotic wounds, alginates or foams for heavy exudate, hydrocolloids for moderate exudate to maintain moist wound environment 1, 2, 4
- Proper moisture balance promotes epithelialization and reduces pain 1, 2
E - Edge Advancement
- Monitor wound size reduction: wounds should decrease by ≥50% within 4 weeks of standard care; failure indicates need for adjunctive therapies 5
- Consider adjunctive therapies only after 4 weeks of failed standard care: electrical stimulation for pressure ulcers (stage 2-4), negative pressure wound therapy for post-surgical diabetic wounds, or autologous leucocyte-platelet-fibrin patch for diabetic foot ulcers 6, 5
Critical Pitfalls to Avoid
- Never use adjunctive therapies as monotherapy without concurrent sharp debridement, appropriate dressings, pressure offloading, and infection control 4, 5
- Do not continue ineffective standard care beyond 4 weeks without considering treatment modification or advanced therapies 5
- Avoid obtaining wound cultures from uninfected wounds as this leads to misdiagnosis and inappropriate antibiotic use 1, 2
- Do not use negative pressure wound therapy for non-surgical diabetic foot ulcers as strong evidence shows no benefit 6
