What is the recommended treatment for pressure ulcers (bedsores)?

Treatment of Pressure Ulcers (Bedsores)

Use hydrocolloid or foam dressings as your primary wound treatment, supplement with protein or amino acids, and consider electrical stimulation for wounds that are slow to heal. 1

Core Treatment Algorithm

The American College of Physicians provides the most authoritative guidance for pressure ulcer treatment, based on systematic review of evidence through 2014 1. Here's how to approach treatment:

1. Nutritional Support (First-Line)

Provide protein or amino acid supplementation to all patients with pressure ulcers to reduce wound size 1. This recommendation applies particularly to patients with nutritional deficiencies, though the optimal dose remains undefined. Protein supplementation works in conjunction with standard wound care, not as a standalone therapy.

Important caveat: Vitamin C supplementation showed no benefit compared to placebo, so don't waste resources on it 1.

2. Wound Dressing Selection (First-Line)

Choose hydrocolloid or foam dressings over traditional gauze 1. The evidence shows:

• Hydrocolloid dressings are superior to gauze for reducing wound size
• Hydrocolloid and foam dressings perform similarly for complete wound healing
• Both are better than doing nothing or using basic gauze

The practical advantage: these dressings maintain a moist wound environment and require less frequent changes than gauze, reducing both cost and patient discomfort.

3. Electrical Stimulation (Adjunctive Therapy)

Add electrical stimulation for stage 2-4 ulcers that aren't healing adequately with standard care 1. This has moderate-quality evidence showing it accelerates healing rates.

Watch for: Skin irritation is the most common adverse effect, and frail elderly patients are more susceptible to complications 1. Don't use this as first-line therapy—reserve it for wounds not responding to dressings and nutrition.

What NOT to Do (High-Value Care Considerations)

The ACP explicitly recommends against routine use of advanced support surfaces (alternating-air beds, low-air-loss beds) because the evidence is insufficient and costs are substantial 1. Standard pressure relief through repositioning is adequate for most patients.

Insufficient evidence exists for:

• Hyperbaric oxygen therapy (commonly used but unproven) 1
• Negative-pressure wound therapy 1
• Zinc supplementation 1
• Most topical agents beyond basic wound dressings 2

Evidence Quality and Clinical Reality

Critical limitation: All three main recommendations from the ACP guideline are graded as "weak" with low-to-moderate quality evidence 1. The relationship between wound size reduction and complete healing remains poorly defined—many studies measured intermediate outcomes rather than complete healing 1.

This means: The evidence base for pressure ulcer treatment is surprisingly weak. A 2017 Cochrane review of 51 studies found the network of evidence too sparse to determine which treatments work best 2. More recent guidelines from Japan (2023) 3 and the Wound Healing Society (2024) 4 acknowledge these same limitations.

Practical Implementation

Given the weak evidence, here's the pragmatic approach:

1. Start immediately with hydrocolloid or foam dressings (not gauze)
2. Add protein supplementation if any concern for malnutrition exists
3. Ensure pressure relief through repositioning every 2 hours (don't rely on expensive mattresses)
4. Consider electrical stimulation after 2-4 weeks if healing is inadequate
5. Debride nonviable tissue mechanically as needed 5

Common Pitfalls

• Don't wait for complete nutritional assessment before starting protein supplementation—the trials showing benefit included patients with deficiencies, so err on the side of supplementing 1
• Don't use gauze dressings when hydrocolloid/foam options are available—this is outdated practice 1
• Don't assume expensive = better—advanced support surfaces lack evidence to justify their cost 1
• Monitor for complications in frail elderly patients receiving electrical stimulation 1

The most important principle: Early recognition and immediate treatment prevent progression to stage IV ulcers, which carry significantly higher morbidity, mortality, and treatment costs 5.
