When Robert’s father moved in after his stroke, Robert assumed the biggest challenges would be medication schedules and physical therapy appointments. He never expected that a quarter-sized red spot on his dad’s tailbone would spiral into a wound that took seven months, three specialist visits, and over $40,000 to heal. The worst part? It was preventable.

Pressure sores claim roughly 60,000 lives in the United States each year and cost the healthcare system an estimated $26.8 billion annually, according to a peer-reviewed cost-of-illness analysis published in the International Wound Journal.¹ The average incremental hospital cost attributable to a single hospital-acquired pressure injury is $10,708 per patient, with Stage 3 and Stage 4 wounds driving the vast majority of that spending.¹ That figure is staggering on its own. But what makes it genuinely tragic is this: the vast majority of pressure injuries are preventable with the right knowledge, the right routine, and the right equipment.²

If you’re caring for someone who spends most of their day in bed or a wheelchair, this guide is your command center for pressure sore prevention and treatment at home.

What Are Pressure Sores? Understanding the Threat

Pressure sores, also called pressure injuries, pressure ulcers, or bed sores, are areas of damaged skin and tissue caused by sustained pressure that cuts off blood flow. They typically form over bony prominences, the spots where bone sits closest to the skin surface: the sacrum (tailbone), heels, hips, shoulder blades, and the back of the head.

The mechanism is straightforward. When a person lies or sits in one position, their body weight compresses the soft tissue between bone and whatever surface supports them. That compression squeezes blood vessels shut. Without blood flow, cells are starved of oxygen and nutrients. Tissue begins to die. On a standard mattress, this process can begin in as little as two hours.³

Three forces work together to cause damage:

Pressure is the primary culprit, compressing tissue against bony areas
Shear occurs when skin moves in one direction while deeper tissue moves in another, such as when a person slides down in bed
Friction damages the outer skin layer during repositioning or when skin drags across sheets

What surprises most family caregivers is the speed. A pressure injury can progress from a faint red mark to an open wound exposing muscle and bone within days if left unaddressed. Older adults face compounded risk because aging skin is thinner, less elastic, and heals more slowly.

The 6 Stages of Pressure Injuries: NPIAP Classification

The National Pressure Injury Advisory Panel (NPIAP), in collaboration with the European Pressure Ulcer Advisory Panel (EPUAP) and the Pan Pacific Pressure Injury Alliance (PPPIA), classifies pressure injuries into four numbered stages plus two additional categories. This six-category staging system, formally defined in the 2016 NPIAP update and reinforced in the 2019 international clinical practice guideline, is the globally recognized standard for clinical assessment and treatment planning.⁴

Stage 1: Non-Blanchable Erythema

The skin is intact but shows a persistent red area over a bony prominence. When you press the spot with your finger, the redness does not fade to white (this is called “non-blanchable”). On darker skin tones, the area may appear purple, blue, or darker than surrounding skin rather than red. The spot may feel warmer, firmer, or softer than nearby tissue.

What to do at home: This is your early warning. Remove all pressure from the area immediately. Reposition your loved one so the affected spot is completely offloaded. Check the spot every two hours. If the redness resolves within 30 minutes of pressure relief, the tissue is recovering. If it persists beyond 24 hours, contact your healthcare provider.

Stage 2: Partial-Thickness Skin Loss

The wound presents as a shallow, open area with a red or pink wound bed. You may also see an intact or ruptured blister filled with clear or blood-tinged fluid. There is no dead tissue (slough) visible. This stage is painful.

What to do at home: Keep the wound clean with gentle saline irrigation. Apply a moisture-retentive dressing as recommended by your healthcare provider. Continue complete pressure offloading. Monitor daily for signs of infection (increasing redness, warmth, swelling, odor, or drainage). Contact your provider if the wound is not improving within one to two weeks.

Stage 3: Full-Thickness Skin Loss

The entire thickness of the skin is destroyed. Subcutaneous fat may be visible in the wound, but bone, tendon, and muscle are not exposed. You may see slough (yellowish dead tissue) in the wound bed. The wound may have rolled edges and can be deeper than it appears due to undermining or tunneling beneath the skin surface.

What to do at home: This stage requires professional wound care assessment. Contact your healthcare provider or a wound care specialist. Do not attempt to clean or debride this wound without professional guidance. Continue pressure offloading and nutritional support while awaiting evaluation.

Stage 4: Full-Thickness Skin and Tissue Loss

The wound extends through all layers of skin and into deeper structures. Exposed bone, tendon, muscle, ligament, or cartilage may be directly visible or palpable. Slough or eschar (dark, leathery dead tissue) may be present. Tunneling and undermining are common.

What to do at home: Seek immediate professional wound care. Stage 4 wounds require specialized treatment that may include surgical debridement, advanced wound dressings, negative pressure wound therapy, or skin grafting. Economic analyses estimate per-patient treatment costs for complicated Stage 3 and Stage 4 pressure injuries in the range of $20,900 to $151,700, depending on the care setting and complications involved.⁵ These wounds can take months or years to heal and carry significant risk of life-threatening infection.

Unstageable: Obscured Full-Thickness Loss

The wound bed is covered by slough or eschar so thick that the true depth cannot be determined. Once the dead tissue is removed (by a professional), the wound will be revealed as Stage 3 or Stage 4.

What to do at home: Do not attempt to remove the covering tissue yourself. One important exception: stable, dry eschar on the heel (it appears as a hard, dark “cap”) should be left intact and monitored, as it serves as the body’s natural protective cover. Contact your wound care provider for all other locations.

Deep Tissue Pressure Injury

The skin is intact but shows a persistent, non-blanchable area that is deep purple or maroon. There may be a blood-filled blister. This injury originates in deeper tissue layers and can evolve rapidly. Within days, it may deteriorate to reveal the full extent of damage, which is often far worse than the surface suggests.

What to do at home: Treat this as urgent. Remove all pressure from the area. Contact your healthcare provider within 24 hours. Monitor closely because these injuries can progress dramatically and quickly. The surface appearance dramatically underestimates the damage beneath.

When to Call 911 or Go to the Emergency Room

Seek emergency care if you observe any of the following alongside a pressure injury:

Fever above 100.4 degrees F (38 degrees C) (may indicate systemic infection or sepsis)⁶
Red streaks extending outward from the wound
Foul-smelling drainage or significant pus
Rapid deterioration of the wound over hours rather than days
Confusion, rapid heart rate, or chills in combination with a wound (signs of sepsis)

Who Is at Risk? Assessing Your Loved One’s Vulnerability

Not everyone who spends time in bed develops pressure sores. Risk depends on a combination of factors that healthcare professionals assess using validated tools. The most widely used is the Braden Scale, which evaluates six categories to produce a risk score. A 2021 systematic review and meta-analysis of 60 studies involving approximately 49,326 individuals found that the Braden Scale has moderate predictive validity, with a pooled sensitivity of 0.78, specificity of 0.72, and an area under the curve (AUC) of 0.82.⁷ A score of 18 or below is the recommended cutoff for initiating a comprehensive prevention plan.⁷

While the full Braden Scale is designed for clinical use, you can perform a simplified risk assessment at home by evaluating these same six areas:

Your Home Risk Assessment Checklist

1. Mobility — Can your loved one change their body position independently?

Moves freely in bed without help = Lower risk
Needs occasional help to shift position = Moderate risk
Cannot reposition without full assistance = High risk

2. Activity Level — How much time do they spend out of bed?

Up and walking regularly = Lower risk
Limited to a chair for most of the day = Moderate risk
Confined to bed most or all of the time = High risk

3. Sensory Perception — Can they feel and respond to discomfort?

Feels pain and pressure normally, communicates clearly = Lower risk
Reduced sensation in one or two limbs, or sometimes confused = Moderate risk
Cannot feel or communicate pain/pressure = High risk

4. Moisture Exposure — How often is their skin exposed to moisture?

Skin is usually dry, continent = Lower risk
Occasionally incontinent, skin sometimes damp = Moderate risk
Frequently or always wet from incontinence, perspiration, or wound drainage = High risk

5. Nutrition — Are they eating and drinking adequately?

Eats most meals, adequate protein and fluid intake = Lower risk
Eats less than half of meals, limited protein = Moderate risk
Very poor intake, refuses meals, unable to eat = High risk

6. Friction and Shear — Do they slide in bed or need repositioning help?

Moves independently, maintains good position = Lower risk
Needs moderate assistance, occasionally slides = Moderate risk
Requires maximum help, frequently slides down in bed = High risk

Interpreting your results: If your loved one scores “high risk” in two or more categories, pressure injury prevention should be a top daily priority. Three or more high-risk areas means you should discuss a formal prevention plan with their healthcare provider and seriously evaluate your support surface and repositioning equipment.

A 2025 systematic review in BMC Geriatrics found that immobility and incontinence were the two strongest predictors of pressure injury in older adults, each increasing risk by more than four times (OR = 4.54). Nutritional risk tripled the likelihood of developing a wound (OR = 3.00).⁸

Additional Risk Factors to Watch

Beyond the six Braden categories, several conditions increase pressure injury risk:

Diabetes — impairs circulation and slows wound healing
Peripheral vascular disease — reduces blood flow to extremities
History of previous pressure injuries — once skin has broken down, that area remains permanently vulnerable
Medications — corticosteroids thin the skin; blood thinners increase bruising; sedatives reduce movement
Cognitive impairment — dementia or delirium reduces a person’s ability to shift their own weight or communicate discomfort
Recent surgery or acute illness — extended periods of immobility during and after procedures

Prevention: Your First Line of Defense Against Pressure Sores

Pressure sore prevention and treatment begins, always, with prevention. The 2019 EPUAP/NPIAP/PPPIA international clinical practice guideline recommends a multi-component prevention bundle combining repositioning, appropriate support surfaces, skin care, and nutritional optimization.² Think of these as the three pillars holding up your loved one’s skin integrity.

Pillar 1: Repositioning

Regular repositioning is the most fundamental prevention measure. When your loved one changes position, blood flow returns to tissue that was compressed, delivering oxygen and nutrients that keep cells alive.

The traditional guideline calls for repositioning every two hours. However, recent high-quality evidence has added important nuance. A 2021 Cochrane systematic review found no statistically significant difference in pressure injury incidence between two-hourly and four-hourly repositioning (Risk Ratio approximately 1.06, 95% CI 0.80-1.41).⁹ The TEAM-UP pragmatic trial, conducted in nursing homes and published in 2022, confirmed that repositioning intervals could be safely extended to four hours without increasing pressure injury rates, provided residents were on high-density foam mattresses. Notably, staff compliance was significantly higher at four-hour intervals (95%) compared to two-hour intervals (80%).¹⁰

The current clinical consensus favors individualized repositioning schedules based on your loved one’s specific risk level, body weight, skin condition, and the quality of their support surface. On a high-performance mattress, some individuals can safely extend repositioning intervals to three or four hours.²

For the complete evidence behind repositioning schedules, practical techniques for turning someone safely (including solo methods), and guidance on building a sustainable day-and-night protocol, read our detailed guide on how often you should turn a bedridden patient.

Pillar 2: The Right Support Surface

The mattress your loved one rests on determines how much pressure their skin endures every second of every day. A standard consumer mattress or a basic hospital foam pad concentrates pressure at bony prominences. A properly selected support surface redistributes that pressure across a larger area or, in the case of alternating pressure systems, periodically eliminates it entirely.

There are three main categories of support surfaces for home use:

Pressure-redistributing foam mattresses spread body weight across a wider surface. Best for moderate-risk individuals who can assist with repositioning.
Hybrid mattresses combine foam with individually wrapped coils for targeted pressure relief and comfort. Good for individuals who spend extended time in bed but are not at the highest risk level.
Alternating pressure mattresses use air-filled cells that cyclically inflate and deflate, periodically removing all pressure from specific skin areas. These are the clinical standard for high-risk individuals and those with existing wounds.

The largest randomized controlled trial comparing these approaches, the PRESSURE 2 trial involving 2,029 high-risk patients, found that alternating pressure mattresses modestly delayed the onset of new pressure injuries compared to high-specification foam mattresses during the treatment phase (HR = 0.66, 95% CI 0.46-0.93). However, this advantage did not maintain statistical significance over the full follow-up period (HR = 0.76, 95% CI 0.56-1.04).¹¹ Comfort is an important consideration: more patients requested to switch away from alternating pressure mattresses due to pump noise and the sensation of air cells affecting sleep.¹¹

Choosing the right mattress is one of the most impactful decisions you will make. Our complete comparison guide walks you through how to choose the best mattress for bedridden patients based on your family member’s actual care needs and risk level.

If your loved one is at high risk or has an existing pressure injury, alternating pressure therapy may be specifically indicated. Learn how these systems work, who genuinely needs one, and how to choose the right model in our guide to alternating pressure mattresses for home use.

Pillar 3: Daily Skin Care

Healthy, well-maintained skin resists breakdown longer than compromised skin. A consistent daily skin care routine addresses moisture management, skin inspection, nutrition, and incontinence care, the factors that determine whether your loved one’s skin can withstand the pressures of extended bed rest.

Moisture is a particularly dangerous accelerant. Skin exposed to urine or fecal matter develops incontinence-associated dermatitis, a condition affecting up to 50% of incontinent adults in long-term care. Damage from moisture exposure can begin within 10 to 15 minutes of contact.¹²

For a structured morning and evening skin care protocol, product recommendations, and the equipment framework that makes daily care sustainable, read our comprehensive guide on skin care for bedridden elderly at home.

The Right Equipment Makes Pressure Sore Prevention Sustainable

Here is the reality most caregivers discover within the first few weeks: prevention routines built on willpower alone do not last. The 2 a.m. alarm for repositioning. The daily skin inspections. The constant vigilance. Without the right equipment, caregiver burnout becomes the biggest threat to your loved one’s skin integrity.

The right care equipment doesn’t replace your effort. It multiplies it. It makes each repositioning safer and less physically taxing. It reduces the pressure your loved one’s skin endures between turns. It gives you the positioning options that clinical guidelines recommend but manual effort cannot achieve.

SonderCare’s Integrated Prevention Ecosystem

Effective pressure sore prevention and treatment requires three equipment categories working together: a bed that enables proper positioning, a mattress that manages pressure, and accessories that support daily care.

The Bed: Positioning and Caregiver Support

The SonderCare Aura Premium Home Hospital Bed ($6,999) provides the positioning capabilities that clinical guidelines recommend for pressure injury prevention:

Hi-Lo adjustment (10″ to 39″) lets caregivers raise the bed to a safe working height during repositioning and skin inspections, reducing back injuries
Trendelenburg and Reverse Trendelenburg positioning promotes circulation and facilitates fluid redistribution
Cardiac Chair and Zero Gravity positions offload the sacrum, the most common pressure injury location, during prolonged sitting periods
FallSafe Ultra-Low Height (10″ platform, 17″ to mattress top) prevents fall-related injuries that compound skin damage

For families seeking furniture-grade aesthetics that preserve dignity, the Aura Platinum ($8,499) adds fully upholstered Crypton fabric side panels that make a hospital bed look like a premium piece of bedroom furniture. Individuals who need additional space can select the Aura Extra Wide Premium ($8,999) at 48″ width.

For families with more limited budgets, the Impulse Residential Bed ($3,999) provides head and knee articulation with hi-lo adjustment at a lower price point, though it does not include Trendelenburg, Zero Gravity, or ultra-low positioning.

The Mattress: Your 24-Hour Prevention Partner

Your choice of SonderCare mattress depends on your loved one’s risk level:

Comfort Mattress ($899) — Visco memory foam with cooling gel and fluid-proof cover. Appropriate for lower-risk individuals with good mobility and skin integrity.
Dream Bamboo Quilt-Top ($1,299) — Bamboo fiber top with reversible soft/firm surfaces and enhanced pressure redistribution. A strong mid-range option for moderate-risk individuals.
Signature Hybrid ($1,799) — Individually wrapped pocket coils beneath multiple foam layers with a copper-infused antimicrobial cover. Excellent pressure relief with superior airflow. Ideal for individuals spending extended hours in bed.
Alternating Pressure Air Mattress ($2,999) — 18 air bladders with an electric pump system cycling on timed intervals. The clinical-grade option for high-risk individuals and those with existing or healing pressure injuries.

Accessories That Support Prevention

Overhead Trapeze Helper Bar ($369) — Enables your loved one to assist with their own repositioning, building independence while reducing caregiver strain
Protective Rail Pads ($99) — Prevents friction injuries against bed rails during repositioning
Underbed Auto-Nightlight ($219) — Motion-activated illumination for safer nighttime transfers

The Cost-of-Prevention Argument

Here is the math that every family caregiver should see. A complete SonderCare prevention setup, including the Aura Premium bed, an Alternating Pressure Air Mattress, and key accessories, runs approximately $10,000 to $11,000.

Economic analyses estimate per-patient costs for complicated Stage 3 and 4 pressure injuries in the range of $20,900 to $151,700.⁵ The total national annual cost for hospital-acquired pressure injuries in the United States exceeds $26.8 billion.¹ Beyond the financial toll, a Stage 4 wound means months of specialized wound care, potential surgical intervention, severe pain, dramatically reduced quality of life, and significant risk of fatal infection.

Prevention equipment is not an expense. It is the most cost-effective investment you can make in your loved one’s care.

Treatment: What to Do When Prevention Is Not Enough

Even with the best prevention routine, pressure injuries can develop. Chronic illness, acute health changes, or gaps in care during hospital stays or transitions can compromise skin integrity despite your best efforts. Knowing how to respond at each stage gives your loved one the best chance of healing.

Stage-by-Stage Response Guide

Stage 1 (Red spot, intact skin):
1. Remove all pressure from the affected area immediately
2. Reposition so the red area is completely offloaded
3. Keep the area clean and dry
4. Apply a moisture barrier cream if the area is near incontinence exposure
5. Monitor every two hours for improvement or progression
6. Contact your healthcare provider if redness persists beyond 24 to 48 hours

Stage 2 (Shallow wound or blister):
1. Gently clean with saline solution or clean lukewarm tap water (not hydrogen peroxide or iodine, which are cytotoxic and damage healing tissue).¹³ The Wound Healing Society and NICE guidelines both recommend pH-balanced, non-irritating solutions for routine wound cleansing.
2. Apply a moisture-retentive dressing as recommended by your provider
3. Maintain complete pressure offloading on the wound site
4. Monitor daily for signs of healing (wound edges drawing together, pink tissue forming)
5. Contact your provider if the wound is not showing improvement within two weeks or shows signs of infection

Stage 3 and Beyond (Deep wounds):
Professional wound care is essential at this stage. Your role shifts to supporting the treatment plan:
1. Follow wound care provider instructions exactly for dressing changes
2. Maintain aggressive pressure offloading using appropriate support surfaces
3. Optimize nutrition with adequate protein (1.25 to 1.5 grams per kilogram of body weight daily) and hydration¹⁴
4. Keep a wound measurement log (length, width, depth) at each dressing change
5. Watch for and immediately report signs of infection

Nutrition for Wound Healing

When a pressure injury is present, your loved one’s nutritional needs increase significantly. Healing wounds consume calories and protein at an accelerated rate. The Wound Healing Society (2023), NPIAP/EPUAP/PPPIA (2019), and the European Society for Clinical Nutrition and Metabolism (ESPEN) all recommend increased protein and calorie intake for individuals with pressure injuries who are malnourished or at nutritional risk.¹⁴

Protein: Increase to 1.25 to 1.5 g/kg body weight daily (for a 150 lb person, that is roughly 85 to 100 grams of protein per day). For individuals with large, severe Stage 3 or 4 injuries, this may be increased to 1.5 to 2.0 g/kg/day under clinical supervision.¹⁴
Calories: Increase to 30 to 35 calories per kilogram of body weight daily
Hydration: Minimum 1 mL per calorie consumed (roughly 2,000 to 2,500 mL daily)
Vitamin C and Zinc: Both support collagen synthesis and immune function; discuss supplementation with your provider
Albumin levels: Ask your provider to monitor serum albumin as a marker of nutritional status

A randomized controlled trial by Cereda et al. found that a high-protein oral nutritional supplement enriched with arginine, zinc, and antioxidants produced a 60.9% reduction in pressure ulcer area over eight weeks, compared to 45.2% with a standard control supplement in malnourished patients.¹⁵

Important caution: High-protein recommendations must be adjusted for individuals with severe kidney disease (CKD Stages 3-5) who are not on dialysis. In these cases, protein intake is typically restricted to 0.55 to 0.8 g/kg/day to avoid further kidney damage. Always consult your loved one’s physician before implementing a high-protein diet if renal impairment is present or suspected.¹⁴

Warning Signs That Require Immediate Medical Attention

Contact your healthcare provider the same day if you notice:

A wound that is getting larger despite treatment
Increased pain, redness, warmth, or swelling around the wound
New drainage that is cloudy, green, or foul-smelling
Black or dark tissue developing in the wound bed
Exposed bone, tendon, or muscle

Karen’s story illustrates why timing matters. She noticed increasing redness around her husband’s Stage 2 sacral wound on a Tuesday but waited until his scheduled nursing visit on Thursday. By Thursday, the wound had deepened to Stage 3 with early signs of infection. Those 48 hours cost an additional two months of treatment. When you see changes, do not wait for the next scheduled visit. Call.

Medicare, Insurance, and Paying for Prevention Equipment

Navigating insurance coverage for pressure injury prevention equipment can feel as overwhelming as the caregiving itself. Here is what you need to know.

What Medicare Covers

Medicare Part B covers certain durable medical equipment (DME) for home use when prescribed by a physician, including hospital beds and pressure-reducing support surfaces. Coverage is governed by specific Local Coverage Determinations (LCDs) that define medical necessity criteria for each equipment category.¹⁶

Hospital beds: Medicare covers basic semi-electric hospital beds when a doctor certifies medical necessity. Medicare pays 80% of the approved amount after the annual deductible ($283 in 2026). You are responsible for the remaining 20% coinsurance. A Medigap supplemental plan may cover some or all of that 20%.

Support surfaces: Medicare Part B covers pressure-reducing support surfaces when your doctor prescribes them for home use:

Group 1 surfaces (foam, gel, and air overlays) require that the beneficiary is completely immobile, OR has limited mobility plus at least one additional condition (impaired nutrition, incontinence, altered sensory perception, or compromised circulation), OR has an existing pressure ulcer on the trunk or pelvis with at least one of those additional conditions.¹⁶
Group 2 surfaces (alternating pressure pads and powered flotation systems) are reserved for more severe cases: multiple Stage 2 ulcers that have not improved after one month on a Group 1 surface with a comprehensive treatment program, OR large or multiple Stage 3 or 4 ulcers, OR a recent myocutaneous flap or skin graft for a pressure ulcer.¹⁶

What Medicare Does Not Cover

Medicare’s DME benefit covers basic equipment. It generally does not cover:

Fully electric hospital beds (only semi-electric for most beneficiaries)
Advanced positioning features like Trendelenburg, Zero Gravity, or ultra-low height
Premium mattress upgrades beyond the basic support surface category
Furniture-grade aesthetics, upholstered panels, or design features
Most accessories beyond basic safety rails

This creates a gap between what clinical best practices recommend and what basic insurance will fund. Many families choose to invest in higher-quality equipment privately because the clinical and quality-of-life benefits exceed what Medicare-approved basic models provide.

Documentation Tips for Insurance Claims

If you are pursuing insurance coverage for any prevention equipment:

Get a written prescription from your loved one’s physician specifying the medical necessity
Document the diagnosis and specific risk factors (immobility, incontinence, history of pressure injuries)
Use a Medicare-enrolled DME supplier for any items you want covered
Keep records of all wound assessments, Braden Scale scores, and care plan documentation
Appeal denials — initial denials are common and many are overturned on appeal

A Standard Written Order (SWO) from the treating practitioner is required before the supplier can submit a claim. The SWO must contain the beneficiary’s name, a description of the item, quantity, the practitioner’s name and NPI, the date of the order, and the practitioner’s signature.¹⁶

The Private-Pay Advantage

Many SonderCare families choose to purchase equipment independently rather than navigating insurance restrictions. The benefits include:

No equipment limitations — choose the bed, mattress, and features that match your loved one’s actual needs
Immediate delivery — no waiting for insurance authorization (Rush delivery available in 1 to 3 business days)
Higher quality — premium equipment designed for long-term home use, not the minimum covered specification
Dignity preserved — furniture-grade design that doesn’t transform a bedroom into a clinical space

When you consider that a complete premium prevention setup costs a fraction of what a single advanced pressure injury costs to treat, the private-pay path often makes the most financial sense, even before factoring in the pain, suffering, and quality-of-life impact.

Frequently Asked Questions About Pressure Sore Prevention and Treatment

How quickly can a pressure sore develop?

Tissue damage can begin in as little as two hours of unrelieved pressure on a standard surface.³ For older adults with thin skin, poor circulation, or nutritional deficiencies, the timeline can be even shorter. This is why regular repositioning and a quality support surface are not optional — they are essential.

What is the most common location for pressure sores?

The sacrum (tailbone) is the most frequently affected area, followed by the heels, hips (greater trochanter), and ischial tuberosities (sitting bones). A systematic review found the heel (34.1%) and sacrum (27.2%) account for the majority of pressure injuries in long-term care settings.¹⁷

Can a pressure sore heal on its own?

Stage 1 pressure injuries can often resolve within 24 to 72 hours with complete pressure offloading and basic care. Stage 2 wounds may take two to four weeks to heal with proper treatment. Stage 3 and 4 wounds require professional intervention, can take months to years to heal, and some may never fully close without surgical intervention.

Do alternating pressure mattresses really work?

Yes, though the evidence is more nuanced than often reported. Alternating pressure mattresses are effective compared to standard hospital foam mattresses. The PRESSURE 2 trial, the largest randomized controlled trial on this topic with 2,029 high-risk patients, found that alternating pressure mattresses modestly delayed the onset of new pressure injuries during the treatment phase compared to modern high-specification foam mattresses (HR = 0.66, 95% CI 0.46-0.93), though the overall difference did not reach statistical significance across the full follow-up (HR = 0.76, 95% CI 0.56-1.04).¹¹ Alternating pressure mattresses remain the clinical standard of care for high-risk individuals and those with existing wounds. For a detailed breakdown, read our guide on alternating pressure mattresses for home use.

How do I know if a pressure sore is infected?

Watch for increasing redness or warmth around the wound, swelling, cloudy or foul-smelling drainage, increasing pain, fever, and any red streaks extending from the wound. If you observe any of these signs, contact your healthcare provider the same day. Untreated wound infections can progress to cellulitis, osteomyelitis (bone infection), or sepsis.

Should I use donut-shaped cushions for pressure relief?

No. Ring-shaped or “donut” cushions actually concentrate pressure around the wound edges and reduce blood flow to the center area. Clinical guidelines specifically recommend against their use.² Use flat pressure-redistributing cushions or specialized wound offloading devices instead.

Your Action Plan: Where to Start Today

You’ve read the research. You understand the stages. You know the risk factors. Now it’s time to act. Here is your prioritized checklist, organized by urgency.

This Week: Assessment and Immediate Actions

[ ] Perform the home risk assessment using the six-category checklist in this guide
[ ] Inspect all bony prominences (sacrum, heels, hips, shoulder blades, back of head) for any existing skin changes
[ ] Evaluate your current mattress — if it is a standard consumer mattress or a basic foam pad, it is likely inadequate for someone spending more than 12 hours a day in bed
[ ] Establish a repositioning schedule based on your loved one’s risk level and current support surface
[ ] Check nutritional intake — is your loved one getting adequate protein, fluids, and calories?

This Month: Equipment and Routine

[ ] Upgrade your support surface if the current mattress does not match your loved one’s risk level
[ ] Evaluate your bed — does it offer the height adjustment and positioning options caregivers need for safe repositioning and skin inspection?
[ ] Implement a daily skin care routine using our skin care protocol for bedridden elderly
[ ] Set up a wound documentation system — a simple notebook or phone photos with dates work well
[ ] Address incontinence management — moisture is the number one accelerant of skin breakdown

Ongoing: Sustainable Prevention

[ ] Reassess risk monthly or whenever your loved one’s condition changes
[ ] Rotate repositioning strategies to prevent caregiver fatigue and ensure coverage of all vulnerable areas
[ ] Monitor nutrition and weight — unintentional weight loss increases pressure injury risk
[ ] Schedule regular healthcare provider check-ins to review skin integrity and adjust the prevention plan
