Pressure Injury Prevention: Risk Screening, Skin Protection & Repositioning Bundles
Sacral redness often appears while the patient is still comfortable. Pressure injury prevention is a continuous nursing bundle—screen risk, protect skin from moisture and shear, match support surfaces, and reposition before tissue fails—not a one-off mattress order. This guide links skin assessment findings to action, pairs with turning and repositioning, and clarifies when to escalate to tissue viability or medical review.

Quick facts
Key takeaway
Prevention wins when you treat pressure, shear, friction, and moisture together: score risk on admission and after major changes, inspect bony prominences every pass, reposition to off-load—not only chart a timer—and escalate the first non-blanching change before an open wound forms.
Quick procedure summary
| Item | Detail |
|---|---|
| Procedure name | Pressure injury prevention (pressure ulcer prevention) |
| Also known as | Bedsore prevention; decubitus ulcer prevention; skin breakdown prevention |
| Category | Wound care / skin integrity nursing |
| Clinical purpose | Identify patients at risk; reduce sustained pressure and shear; maintain skin integrity; prevent Category 1–4 pressure injuries |
| Who performs | Registered nurses lead the bundle; assistive staff reposition per delegation; tissue viability and medical teams advise on surfaces and treatment |
| Typical time | Continuous—risk screen on admission; skin check each round; repositioning passes per care plan (often 10–20 minutes when full turn with skin exam) |
| Settings | Acute wards, critical care, rehabilitation, long-term care, community nursing, perioperative pathways |
What is pressure injury prevention?
Pressure injury prevention is the coordinated nursing and multidisciplinary work to stop localized skin and soft-tissue damage caused by sustained pressure, often combined with shear, friction, moisture, poor perfusion, or limited nutrition. It is not a single intervention—it is a bundle repeated across the shift: risk screening, head-to-toe skin assessment, moisture management, safe patient positioning, appropriate support surfaces, and early referral when skin changes.
International classification systems (for example NPIAP/EPUAP staging used in pressure injury staging) describe damage after it appears; prevention aims to keep tissue viable before staging is needed. Principles align with Royal Marsden Manual — Pressure ulcers and publicly available guidance such as NICE NG179; proprietary procedure text and illustrations are not reproduced here—follow your licensed manual and local tissue viability policy.
Risk screening: what the score should trigger
Most hospitals use a validated tool (commonly Braden or Waterlow). Institutional protocols may vary for cut-offs and reassessment intervals—always use your organisation's policy, not memorised numbers from another unit.
| Clinical signal | Nursing emphasis |
|---|---|
| New admission or transfer | Complete risk screen within policy timeframe; inspect sacrum and heels before first long lie |
| Lower sensory perception / neuropathy | Patient may not feel discomfort—visualise heels and feet, especially with type 2 diabetes |
| Moisture from urine or stool | Activate continence plan; barrier creams per formulary; do not rely on repositioning alone—see urinary incontinence and fecal incontinence |
| Acute illness with perfusion risk | Watch for cool extremities or mottled skin; align reposition frequency with haemodynamic stability |
| Post-operative immobility | Re-score after major surgery, sedation wean, or unplanned ICU stay; pair with mobility assessment |
A low score without action is a documentation exercise. The score should drive surface requests, repositioning frequency, nutrition referral, and family education—not sit unread in the chart.
MASD vs pressure injury: do not chart the wrong problem
Moisture-associated skin damage (MASD) from urine, stool, perspiration, or wound exudate can erode skin without the classic pressure pattern. Treating it as "just reposition more" misses the driver.
| Feature | Pressure-related change | Moisture-related change |
|---|---|---|
| Typical location | Bony prominences (sacrum, heels, trochanters, occiput) | Skin folds, perineum, buttocks in contact with wet linen |
| Surface appearance | Erythema that may blanch early; later non-blanching or open area | Maceration, denuded epidermis, satellite irritation |
| First nursing fix | Off-load pressure + reposition schedule | Cleanse gently, dry, barrier, absorbent pad, treat incontinence cause |
Both can coexist on the same patient—document each finding separately and notify tissue viability when classification is unclear.
Prevention bundle at the bedside
NICE and major wound societies describe prevention as combined interventions. Use this checklist each shift for high-risk patients:
Shear and friction: the hidden destroyers
Pressure compresses tissue between bone and surface. Shear stretches vessels when the skeleton slides (head-of-bed up + patient slides down). Friction abrades the epidermis during transfers.
- Semi-Fowler without knee flexion increases sacral shear—coordinate with Fowler's position orders.
- Dragging up the bed tears heels and sacrum—use slide sheets and count-with-assist moves.
- Rough linen, wrinkled incontinence pads, and over-tight heel protectors create friction hotspots.
- Lift-and-shift micro-moves for patients who cannot tolerate full turns during instability still redistribute load—document what was achievable.
Support surfaces: nurse role in selection and checks
Mattresses and overlays redistribute pressure; they do not replace repositioning. Nurses usually initiate requests using risk scores and skin findings; procurement and tissue viability confirm appropriateness per local formulary.
| Surface concept | Bedside nursing checks |
|---|---|
| Standard hospital mattress | Confirm intact cover; no bottoming-out feel at sacrum when palpating through sheet (per policy) |
| Pressure-redistributing overlay / mattress | Plugged in, alarm lights functional, settings match weight range; educate patient on less "firm" feel |
| Heel-specific off-loading | Heels suspended or floated; avoid circumferential pressure from poorly fitted boots |
| Chair cushion for out-of-bed time | High-risk patients need chair pressure relief—not only bed equipment |
When an open wound is present, prevention shifts to treatment—coordinate with wound care and negative pressure wound therapy when ordered.
Indications
- All immobile or partially mobile inpatients until risk is ruled low by validated screening
- Patients with existing Category 1 (non-blanching erythema) or open pressure injuries—to stop progression
- Critical care, spinal injury, major orthopaedic, or neurological pathways with expected immobility
- Older adults with frailty, polypharmacy sedation, or acute delirium with confusion
- End-of-life skin changes (Kennedy terminal ulcer) still need comfort-oriented skin plans—goals shift but skin remains a care priority
Cautions and when to pause standard prevention
- Unstable spine or pelvic fracture without a cleared handling plan
- Haemodynamic instability where full turns risk decompensation—use micro-shifts and document limitation
- Suspected unilateral calf DVT—no calf massage; follow VTE pathway
- Open wounds with exposed bone/tendon—position per tissue viability; do not apply unapproved dressings
Geriatric and bariatric patients need equipment matched to weight and width—standard slides may be inadequate. Paediatric prevention uses age-specific tools not detailed here.
Equipment
Preparation
Bedside prevention workflow
Screen and classify risk
Complete or update Braden/Waterlow per policy on admission, transfer, and after major status change. Link score to repositioning frequency and surface requests.
Inspect skin systematically
Use a head-to-sacrum-to-heels pattern; include ears on side-lying patients and medical device contact points. Compare with prior entry in the chart.
Manage moisture and nutrition drivers
Change wet linen; protect perineal skin; escalate poor intake; review blood results such as albumin–globulin ratio only as part of the wider clinical picture—never in isolation.
Reposition with off-loading intent
Execute turns using lift techniques; alternate sides; float heels; avoid 90° lateral hip pressure unless ordered. Document position achieved.
Verify support surface function
Check power, settings, and patient tolerance. Re-educate if patient slides down the bed—address shear, not only pain.
Escalate early skin changes
Notify tissue viability or medical team for non-blanching areas, rapid deterioration, suspected deep tissue injury, or spreading erythema suggesting cellulitis.
Document and hand off
Record risk score, skin findings, interventions, patient tolerance, and next due repositioning or skin check—see documentation standards.
Blanching vs non-blanching: when the plan changes
| Skin finding | Interpretation | Nursing action |
|---|---|---|
| Blanching erythema | Pressure-related hyperaemia that may resolve with off-loading | Increase reposition frequency; confirm surface; re-check within hours |
| Non-blanching erythema | Category 1 pressure injury in many classification systems | Notify tissue viability; photograph per policy; stage formally with ulcer assessment skills |
| Purple/maroon intact skin | Suspected deep tissue injury | Urgent specialist review; avoid aggressive massage or rubbing |
| Open wound or eschar | Established pressure injury | Switch to treatment pathway; measure and describe wound; consult wound care |
Monitoring and escalation
| Finding | Possible concern | Nursing action |
|---|---|---|
| Spreading erythema, warmth, fever | Cellulitis or infection | Notify medical team; obtain vital signs including fever; follow sepsis screening |
| Wound odour, increasing exudate | Infection or necrotic tissue | Notify clinician; obtain wound swab if ordered; reinforce hand hygiene |
| Sudden neurological change during care | Stroke or hypoxia | Stop move; emergency pathway—see stroke context |
| Patient reports heel numbness with cool foot | Perfusion compromise | Notify medical team; avoid tight boots; compare pedal pulses per policy |
Documentation
"09:15 — Braden 11 (high risk). Sacrum: 3 cm blanching erythema, skin intact. Heels floated on pillow. Repositioned 30° left tilt with slide sheet; patient tolerated. Barrier applied after incontinent episode at 08:40. Pressure-redistributing mattress in use. Tissue viability notified; next skin check 13:00."
Avoid charting only "skin intact" without site-specific findings on high-risk patients. Photographs, when policy allows, accelerate handoffs but never replace bedside assessment.
Clinical pearls
- Reposition after every incontinent episode—not only on the two-hour timer.
- Medical devices (nasal bridles, oxygen tubing, cervical collars) cause injuries nurses often miss—include them in skin rounds.
- Chair time without a cushion shifts load to ischial tuberosities—high risk after long bed rest.
- Pair VTE prophylaxis such as enoxaparin with mobilisation when safe—immobility drives both clot and skin risk.
Patient and family teaching
Teach patients who can participate to shift weight every 15–30 minutes in chairs and to report numbness or burning over heels. Families can help with call bells, hydration, and dry bedding—but should not reposition without training. Explain that redness is an early warning, not a normal part of hospitalisation.
NCLEX practice questions
When sacral skin changes before the patient feels pain, practise NCLEX-style clinical judgment practice for pressure injury prevention: priority action after incontinence, select-all-that-apply risk cues, post-intervention skin trends, matrix escalation for new non-blanching areas, and documentation cloze—recognise cues → analyse → prioritise → act → evaluate outcomes.
Unfolding case — rehabilitation unit. Mr. Delgado, 72, has type 2 diabetes with peripheral neuropathy and a Braden score of 12. He is bedbound after a hip fracture repair. Sacral skin shows blanching erythema. Overnight he had two fecal incontinence episodes; linen is damp. A pressure-redistributing mattress is in use. You start the 10:00 skin round and repositioning pass.
Answer key & rationale
Frequently asked questions
What is the difference between pressure injury prevention and turning and repositioning?
Prevention is the full bundle (risk screen, moisture, surfaces, nutrition, skin surveillance). Turning and repositioning is one major component that off-loads tissue.
How often should high-risk patients be repositioned?
Frequency depends on risk score, support surface, perfusion, and tolerance—institutional protocols may vary. There is no universal interval for every patient.
Does a pressure-relieving mattress remove the need for turns?
No. Surfaces redistribute load; repositioning changes where load is applied. Most high-risk patients need both.
When should I notify tissue viability?
Notify for non-blanching erythema, suspected deep tissue injury, rapidly worsening wounds, or when prevention strategies are not maintaining skin integrity.
Can I massage reddened areas to improve circulation?
No. Rubbing damaged or at-risk tissue can worsen injury. Off-load and follow specialist advice.
What should documentation include?
Risk score, specific skin sites, blanching status, moisture interventions, position achieved, surface in use, notifications made, and next check time.
