A Comprehensive Guide to Chronic Wound Care: Causes, Risks, and Home Management

by YDCare Homecare Team | November 7,2025

What is a "Chronic Wound"?

A typical wound should show significant healing within 4–6 weeks. If it fails to close, or exhibits persistent exudate (discharge) and infection, it is classified as a chronic wound. Common types include:

· Pressure Injuries (Bedsores): Caused by prolonged pressure on bony prominences (e.g., tailbone, heels) in bedridden or wheelchair-bound patients.

· Diabetic Foot Ulcers: Resulting from neuropathy (loss of sensation) and poor circulation; prone to infection as patients may not feel injuries.

· Venous Leg Ulcers: Characterized by calf swelling, dark pigmentation, and heavy exudate ("wet" wounds).

· Arterial Ulcers: Caused by poor blood flow. These are painful, have well-defined edges, and appear dry or pale.

· Peristomal Skin Issues: Irritant dermatitis caused by stoma leakage or poor appliance fitting.

Why Won't the Wound Heal?

Successful healing requires good blood supply, zero infection, a moist environment, and healthy wound edges. When a wound becomes "stagnant," it is usually due to:

· Systemic Health Issues: Poorly controlled blood sugar (diabetes), Peripheral Artery Disease (PAD), malnutrition (low albumin), and smoking.

· Biofilm & Recurring Infection: Bacteria can form a "biofilm" on the wound surface, making infections resistant to standard cleaning.

· Physical Irritation: Constant pressure, shear force, friction, or moisture from incontinence.

· Medication Interference: Long-term use of steroids or anticoagulants (blood thinners) can slow down the body’s natural repair process.

The "5-Step Nursing Routine" (Based on T.I.M.E. Concept)

We have adapted the clinical T.I.M.E. concept into a practical 5-step home care routine:

1. Tissue Prep (Cleaning): Cleanse with sterile saline at body temperature to remove debris. Avoid long-term use of harsh irritants like alcohol or hydrogen peroxide.

2. Debridement (Removal): Remove necrotic tissue to speed up healing. This can be done via autolytic methods (hydrogels), mechanical means, or professional sharp debridement by a nurse.

3. Infection/Inflammation Control: Monitor for redness, heat, odor, and increased pain. Use antimicrobial dressings (Silver, Iodine, or PHMB) if prescribed. Seek medical help immediately if redness spreads (cellulitis).

4. Moisture Balance: Maintain a "moist, not wet" environment. Use foams for high exudate or hydrogels for dry wounds to prevent maceration.

5. Edge & Off-loading: Protect wound edges and reduce pressure. Use off-loading insoles for foot ulcers and perform regular repositioning for bedsores.

Dressing Selection Strategy

· Low Exudate/Dry: Hydrogels or hydrocolloids → Promote autolysis and hydration.

· Moderate Exudate: Foam dressings or Alginates.

· High Exudate: Super-absorbent dressings or Alginates with secondary fixation; consider Negative Pressure Wound Therapy (NPWT) if assessed by a professional.

· Infection Risk: Short-term use of Silver or Iodine dressings.

Principle: Choosing the right dressing is more important than changing it frequently. Re-evaluate the wound every 1–3 days.

Expert Tips for Different Situations

· Pressure Injuries: Reposition every 2 hours; use an appropriate pressure-relief mattress; apply barrier creams if incontinence is present.

· Diabetic Foot Ulcers: Strict blood sugar control is vital. Inspect feet daily and never walk barefoot. Treat any skin breakdown immediately.

· Venous Ulcers: If blood flow is adequate (confirmed by a professional ABI test), use compression stockings or bandages and elevate the legs.

· Arterial Ulcers: Avoid compression. These require assessment by a vascular surgeon for potential revascularization.

· Stoma Care: Measure the stoma size accurately to cut the baseplate correctly. Use stoma powder or paste to prevent leakage.

What You Can Do at Home

· Stick to a Routine: Make cleaning, dressing changes, and recording progress a daily habit. Always wash hands thoroughly.

· Nutrition: Focus on protein-rich foods (fish, eggs, meat), Zinc, and Vitamin C to help build new tissue.

· Activity & Circulation: Perform gentle stretching and limb elevation; avoid staying in one position for too long.

· Manage Conditions: Control blood sugar and blood pressure; quit smoking; attend all follow-up appointments.

· Home Safety: Clear floor clutter and wear proper footwear to prevent new injuries.

When to Seek Help

· Fever, chills, or rapidly spreading redness/swelling around the wound.

· Foul odor or a significant increase in pus-like discharge.

· Visibility of tendons, bones, or rapidly expanding black dead tissue.

· Severe leg pain, or toes turning black/cold (sign of critical ischemia).

· No progress after 3–4 weeks, or the wound is getting bigger.
