How to Prevent Skin Breakdown: Nursing Interventions

Skin breakdown in healthcare settings is largely preventable through a combination of nursing interventions that address pressure, moisture, nutrition, and early detection. No single measure works in isolation. The most effective approach layers structured risk assessment with regular repositioning, appropriate support surfaces, skin protection, and nutritional support into a coordinated bundle of care. While the evidence base for individual components varies in strength, the overall direction is clear: consistent, proactive nursing care dramatically reduces the incidence of pressure injuries and related skin damage.

Why Skin Breaks Down in the First Place

Understanding what causes skin breakdown helps explain why prevention requires multiple simultaneous interventions. The primary culprit is sustained pressure over bony prominences like the sacrum, heels, and hips, which compresses blood vessels and starves tissue of oxygen. But pressure alone does not tell the whole story. Shear forces, which occur when skin stays in place while underlying tissue slides (as when a patient slowly slides down in bed), compound the damage. Research measuring blood flow and oxygen levels in loaded skin found that adding shear to normal pressure further reduced both blood perfusion and oxygen delivery, suggesting that shear plays its own distinct role in tissue injury.

Moisture adds a separate pathway to skin damage. Incontinence-associated dermatitis, which develops when skin is repeatedly exposed to urine or stool, involves chemical and physical irritation of the skin barrier that triggers inflammation and tissue breakdown. Although it can look similar to a shallow pressure injury on the surface, the underlying causes differ, and so do the interventions needed to prevent it.

These overlapping but distinct mechanisms are why prevention is not as simple as “turn the patient more often.” A comprehensive plan needs to address pressure redistribution, shear reduction, moisture control, and skin nourishment all at once.

Structured Risk Assessment

Before deciding which interventions a patient needs, nurses rely on validated tools to identify who is at risk. The Braden Scale is the most widely used screening instrument. It scores six domains, including sensory perception, mobility, moisture exposure, nutrition, and friction/shear, producing a composite number that flags patients for preventive care. A systematic review and meta-analysis of the Braden Scale’s accuracy across adult populations found pooled sensitivity around 78% and specificity around 72%, meaning it catches most at-risk patients but also produces a fair number of false positives.

Performance improves in certain populations. Among older hospitalized patients specifically, one cross-sectional study found the Braden Scale had sensitivity of about 85% and specificity of about 86%, suggesting it works particularly well in the group where pressure injuries are most common.

⁴

The Braden Scale gives a global risk score, but it does not tell you which specific body site is about to break down. That gap has led to interest in sub-epidermal moisture (SEM) measurement, a technology that detects fluid accumulation beneath the skin’s surface before any visible damage appears. In a prospective study, SEM readings identified early tissue damage an average of four days before nurses could see it with their eyes, with 100% sensitivity for predicting pressure injuries that later became visible.

⁵

Additional research has confirmed that SEM scanners can complement traditional skin assessment and catch abnormalities before even ultrasound imaging does.

⁶

These devices are still relatively new in clinical practice, but they represent a meaningful shift from reactive detection to proactive, site-specific monitoring.

Assessing Skin in Darker Skin Tones

Standard pressure injury staging relies heavily on visual cues like redness that does not blanch when pressed. This works reasonably well on lighter skin but fails to capture early-stage damage in people with darker skin tones, a problem that contributes to delayed detection and worse outcomes in these patients. Qualitative research with patients and carers found that skin discoloration toward a darker hue than usual was the most commonly recognized sign of altered skin integrity, rather than the classic redness described in textbooks.

⁷

Enhanced assessment techniques are being developed to close this gap. One quality improvement project combined a structured physical assessment protocol with halogen lighting and found that the pairing improved identification of stage 1 pressure injuries in patients with dark skin.

⁸

For nurses, the practical takeaway is to look beyond color changes alone and incorporate touch (localized warmth, firmness, or bogginess), patient-reported pain over bony prominences, and where available, SEM scanning when assessing patients whose skin tone makes visual assessment unreliable.

Repositioning

Regular repositioning to offload pressure from vulnerable areas is perhaps the most fundamental nursing intervention. The classic guidance calls for turning patients every two hours, but the evidence on the ideal frequency and technique is less settled than most nurses realize. A Cochrane review of repositioning trials found that the overall certainty of evidence was very low, making it hard to draw firm conclusions about the best tilt angle or turning schedule.

⁹

That said, specific trials do show real benefits. A randomized controlled trial of older patients found that repositioning every three hours at night using a 30-degree tilt reduced pressure injury incidence from 11% to 3% compared with usual care.

¹⁰

The 30-degree tilt is significant because it shifts body weight off the sacrum without pushing it entirely onto the hip, distributing load more evenly.

One notable nursing home trial compared repositioning intervals of two, three, and four hours and found zero new pressure injuries in any group during the intervention period, though all residents were on appropriate support surfaces.

¹¹

This result suggests that on a good support surface, the exact turning interval may matter less than ensuring turns actually happen. In practice, the biggest problem is not the schedule on paper but the gap between the schedule and what actually occurs at the bedside, a problem that emerging technologies are beginning to address.

Support Surfaces

The mattress or overlay a patient lies on makes a measurable difference. A Cochrane overview and network meta-analysis compared various types and found that reactive air surfaces (such as static air overlays), alternating pressure air mattresses, and reactive gel surfaces all reduced pressure injury rates compared with standard hospital foam mattresses.

¹²

Within those categories, though, the picture gets complicated. A systematic review of alternating pressure air mattresses found inconsistent results: in some studies they outperformed foam mattresses, in others they performed the same or worse than viscoelastic foam or static air options.

¹³

A multi-center observational study of critically ill patients found that a multi-foam core mattress with a laminated cover significantly outperformed an alternating air mattress overlay, with pressure injury rates of about 7% versus 25%.

¹⁴

The practical message is that upgrading from a standard hospital mattress to a specialized pressure-redistribution surface helps, but the “best” surface depends on the patient, the care setting, and whether the surface is maintained properly. Alternating pressure devices, often seen as the gold standard, do not automatically outperform high-quality foam or static air products in every situation. What matters most is matching the surface to the patient’s risk level and ensuring it is actually functioning correctly, a deflated air mattress or a bottomed-out foam pad offers no protection at all.

Skin Care and Moisture Management

Keeping skin clean and appropriately hydrated without stripping its natural barrier is its own discipline. Traditional soap tends to disrupt the skin barrier, dissolve protective lipids, and alter skin pH, all of which leave tissue more vulnerable to breakdown.

¹⁵

Mild pH-balanced cleansers (sometimes called syndets) avoid these effects and maintain the skin’s native structure more effectively. For incontinent patients, cleansing alone is not enough. A barrier product is needed to protect skin from ongoing exposure to moisture and chemical irritants in urine and stool.

A cluster randomized trial in older women with incontinence found that a skin barrier cream significantly reduced redness and improved skin hydration and pH compared with routine care.

¹⁶

When comparing specific barrier products, a study of zinc oxide ointment versus non-irritating barrier films found no significant difference in incontinence-associated dermatitis rates, though the barrier film appeared to delay onset somewhat.

¹⁷

The choice between zinc oxide paste and a liquid barrier film often comes down to practical factors: zinc paste is thicker and harder to remove at each cleaning, while barrier films are easier to apply and wipe off. Either approach is better than no barrier protection at all.

Nutritional Support

Malnutrition is an independent risk factor for skin breakdown, and it is strikingly common in hospital and long-term care populations. Patients who are malnourished heal more slowly and have skin that is less resilient to pressure. A systematic review and meta-analysis found that oral nutritional supplements providing 250 to 500 extra calories per day were associated with a roughly 25% lower incidence of pressure ulcer development compared with routine care.

¹⁸

A randomized trial in hip-fracture patients found that while overall pressure injury rates were similar between supplement and placebo groups, more severe injuries (stage 2 and above) were less common in the supplemented group, and the onset of any injury was delayed.

¹⁹

Protein is particularly important. Current clinical guidelines typically recommend increased protein intake for at-risk patients, along with adequate hydration, calories, and micronutrients like zinc and vitamin C that support tissue integrity. For nurses, the actionable step is ensuring that nutritional screening is part of the admission process and that dietitian referrals happen promptly when deficits are identified.

Medical Device-Related Pressure Injuries

Not all pressure injuries come from beds and chairs. In critical care settings, medical devices like oxygen masks, nasogastric tubes, cervical collars, endotracheal tube holders, and monitoring leads press against skin and can cause localized breakdown. These device-related injuries are common in ICUs and require their own prevention strategies. A systematic review found that effective approaches include nurse education, structured assessment and documentation, repositioning of devices when clinically safe, and the use of protective dressings (particularly hydrocolloid and foam dressings) under devices to cushion the skin.

²⁰

Training makes a concrete difference. One study implementing a dedicated prevention training program for ICU nurses found that the point prevalence of device-related pressure injuries dropped from about 61% to about 28% after the intervention, alongside significant improvements in nurses’ knowledge and prevention behaviors.

²¹

A separate implementation project using a structured evidence-based framework saw device-related injury incidence drop from about 24% to about 4%.

²²

The pattern across these studies is consistent: when nurses are educated specifically about device-related injuries and given clear protocols for assessment, repositioning, and protective dressing use, rates fall sharply.

Wearable Sensors and Turning Compliance

One of the persistent challenges in pressure injury prevention is the gap between the repositioning schedule written in the care plan and what actually happens. Nurses get pulled into emergencies, short-staffed shifts erode routines, and documentation of turns is often inaccurate. Wearable patient sensors that track body position and alert staff when a turn is overdue are emerging as a practical solution.

A pragmatic randomized trial in ICU patients compared a wearable sensor group to standard care and found that turning compliance rose from 54% to 67%, and the rate of hospital-acquired pressure injuries dropped from 2.3% to 0.7% in the sensor group.

²³

Another study found that introducing wearable sensors in a critical care unit pushed repositioning compliance from 55% up to 89%, while the average turning interval shrank from 3.8 hours to 2.3 hours.

²⁴

An integrative review of the wearable sensor literature concluded that these devices consistently increase adherence to turning protocols while decreasing both pressure injuries and associated organizational costs.

²⁵

These tools do not replace nursing judgment, and they introduce their own considerations around patient comfort, sensor adhesion, and alarm fatigue. But in units where turning compliance is a known weak spot, the data supporting their use is growing.

Bundling Interventions Together

Individual interventions are useful, but the strongest prevention strategies combine them into coordinated care bundles. A typical bundle packages risk assessment, repositioning schedules, support surface selection, skin inspection, moisture management, and nutrition screening into a standardized protocol that is applied as a set rather than piecemeal. A systematic review and meta-analysis of pressure injury prevention bundles in hospitals found that bundled care was associated with roughly a 69% lower rate of hospital-acquired pressure injuries compared with usual care, though the evidence came primarily from non-randomized studies with high risk of bias.

²⁶

In pediatric settings, a prevention bundle produced a 57% reduction in pressure injury incidence.

²⁷

In aged care facilities, a program that combined education, practice change, onsite champions, mentorship, and resident engagement produced significant decreases in pressure injury prevalence along with earlier wound identification.

²⁸

The recurring finding across settings is that education alone is not enough. Knowledge improves after training sessions, but lasting reductions in pressure injuries come from pairing education with workflow changes, leadership support, and accountability structures that keep the bundle from sliding back into old habits. The bundle gives every member of the care team a clear, repeatable checklist, and when it is embedded into daily workflow rather than treated as an optional add-on, the results tend to hold.

Special Populations and Unavoidable Skin Changes

Certain patient groups require tailored approaches. In neonatal and pediatric ICUs, where pressure injuries often arise from medical devices rather than immobility, a survey found that about three-quarters of nurses conducted risk assessments on all patients, but only 60% had written prevention care plans in place, suggesting a gap between awareness and formal planning.

²⁹

Bariatric patients present their own challenges: skin folds create warm, moist environments prone to fungal infection and maceration, and standard equipment may not accommodate larger body sizes, making both repositioning and skin inspection more difficult.

At the other end of the spectrum, patients at the end of life can develop skin changes that are not preventable regardless of the quality of care. Terminal ulcers, sometimes called Kennedy ulcers or skin failure, appear as the body’s organ systems shut down, and blood flow to peripheral tissues becomes insufficient to maintain tissue integrity. A scoping review of the literature found broad consensus that terminal ulcers are unavoidable and should not be attributed to substandard care, though the distinction between terminal ulcers and pressure injuries remains imperfectly understood since both tend to appear over bony prominences.

³⁰

Recognizing this distinction matters for nursing teams. Not every wound that develops in a dying patient represents a failure of prevention. Shifting the focus from prevention to comfort care, including pain management, gentle cleansing, and moisture control without aggressive repositioning, respects both the patient’s condition and the clinical reality. At the same time, comfort-focused skin care should not become a blanket excuse for abandoning prevention efforts in seriously ill patients who are not imminently dying. The judgment call between “this patient needs aggressive prevention” and “this patient needs comfort-oriented skin care” is one of the harder clinical decisions in end-of-life nursing.
