Delayed Wound Healing Factors and Complications
Key Points
- Delayed healing results from both local wound conditions and whole-body systemic factors.
- Local barriers include desiccation, maceration, edema, pressure, trauma, and infection.
- Systemic barriers include age-related vascular changes, poor oxygenation, diabetes, and medication effects.
- Major complications include infection, hemorrhage, dehiscence, evisceration, and fistula formation.
Pathophysiology
Wound repair slows when tissue hydration, perfusion, oxygenation, or microbial balance is disrupted. Local injury-zone stressors can block epithelial migration and collagen organization even when treatment is started.
Systemic disease and treatment effects add further delay by impairing circulation, immunity, and cell proliferation. Healing then remains in inflammatory-dominant patterns and complication risk increases.
Classification
- Localized factors: Desiccation, maceration, pressure, trauma, edema/bleeding, infection.
- Systemic factors: Advanced age, venous insufficiency, poor oxygenation, obesity, diabetes, medication effects, smoking/alcohol use.
- Complication set: Infection, hemorrhage, dehiscence, evisceration, fistulas.
Nursing Assessment
NCLEX Focus
Prioritize recognition of treatable healing barriers and urgent complications that require immediate escalation.
- Assess wound moisture balance, surrounding skin integrity, exudate pattern, and signs of infection.
- Screen for systemic barriers: oxygenation deficits, glycemic instability, nutrition gaps, and vascular compromise.
- Monitor for sudden bleeding, wound-edge separation, protrusion signs, or abnormal tract drainage.
- Track symptom progression against expected phase trajectory rather than isolated single findings.
Nursing Interventions
- Correct local barriers early: optimize moisture balance, reduce pressure and shear, and protect periwound skin.
- Coordinate systemic optimization: nutrition support, oxygenation management, glucose control, and medication review.
- Treat potential dehiscence/evisceration as urgent events with immediate provider notification.
- Use consistent, detailed documentation to support serial reassessment and interprofessional decisions.
High-Risk Complication Window
Dehiscence with evisceration risk is a clinical emergency; delayed escalation can cause rapid deterioration.
Pharmacology
| Drug Class | Examples | Key Nursing Considerations |
|---|---|---|
| antibiotics | Broad and targeted agents | Use culture-guided escalation when infection signs emerge. |
| steroids | Chronic corticosteroid therapy | Recognize delayed inflammatory response and increased tissue fragility risk. |
Clinical Judgment Application
Clinical Scenario
A patient with diabetes and chronic venous insufficiency has persistent wound drainage, fragile periwound skin, and worsening pain after initial improvement.
Recognize Cues: Multiple systemic barriers with new local deterioration signs. Analyze Cues: Healing trajectory is no longer progressing as expected and complication risk is rising. Prioritize Hypotheses: Infection plus impaired perfusion are likely delaying repair. Generate Solutions: Intensify local wound management, reassess systemic barriers, and communicate urgent findings. Take Action: Escalate to provider/wound team and implement ordered barrier-correction interventions. Evaluate Outcomes: Drainage and tissue quality trends improve with targeted adjustment.
