A practical guide to choosing the right interventions and equipment

Pressure injuries are still one of the most preventable harm events in aged care and community settings. International guidelines for Pressure Injury Prevention and Treatment 2025 (NPIAP/EPUAP/PAN PAC, 4th edition) estimate that up to 95% of pressure injuries can be avoided with early risk identification and the right interventions. 
The Waterlow Score helps you flag risk early. The next step is turning that score into practical, repeatable actions that protect your resident, patient or client from day one. 

What your Waterlow Score is really telling you 
A Waterlow Score isn’t just a number. It reflects multiple risk factors the international guidelines highlight as critical: mobility, skin condition, continence, nutrition, cognition and underlying health (EPUAP/NPIAP/PPPIA Clinical Practice Guideline, 2019). 
It’s important to note that Waterlow is a risk screening tool, while the International Guidelines provide broader evidence-based prevention recommendations. The two are often used together in practice, but they are not the same thing. 

A simple way to interpret it:

• 10–14: At risk - Subtle changes matter. Early protection can stop minor redness progressing.
• 15–19: High risk - Follow structured prevention routines. Skin needs close monitoring.
• 20+: Very high risk - Act quickly. While this group typically deteriorates faster without active pressure relief, this is a clinical observation rather than a Waterlow-specific statement. 

These ranges align with how the Waterlow tool is typically used across UK, NZ and Australian clinical environments. 

Your step-by-step response by risk level:

At risk (Waterlow 10–14) 
Early actions have the highest impact. 
According to the 2025 International Guideline, recommended actions include: 
* Daily skin checks for colour, heat, firmness or pain 
* Regular movement, including small repositioning shifts 
* Moisture management, especially for continence 
* A supportive static foam mattress and cushion 
* Attention to hydration and nutrition, both essential for skin integrity (NPIAP, 2020) 

High risk (Waterlow 15–19) 
Increase structure and consistency. 
Recommended actions: 
* Skin inspection every shift 
* Document any skin changes (recommendation from NZ Wound Care Society) 
* Structured repositioning, ideally every 2–4 hours depending on tolerance 
* A pressure-relieving foam or hybrid mattress 
* Seating assessments to reduce shear 
* Review of continence tools and moisture-barrier products 
* Adequate protein intake to support tissue health (EPUAP/NPIAP) 

A well-chosen support surface also helps reduce manual handling strain for care teams and keeps repositioning schedules realistic — an important operational benefit for clinical leadership. 

Very high risk (Waterlow 20+) 
This group often needs immediate escalation. 
Guideline-aligned actions: 
* Move quickly to an active surface such as an alternating air mattress 
* Consider lateral turning systems when manual repositioning isn’t possible 
* Increase repositioning frequency 
* Seek specialist support – particularly for bariatric, spinal or complex comorbidities 
* Review seating, transfer techniques and hoist use to reduce shear forces 
* Act on any sign of non-blanchable redness (Stage 1 pressure injury under NPIAP definition) 

Matching the Waterlow Score with the right surface:

Support surfaces should always be selected alongside clinical judgement — a key point reinforced across all international guidelines. 

Spot early warning signs:

The NPIAP highlights four early indicators that predict deterioration:

• Heat
• Colour changes (be mindful of darker skin tones where purple/blue hues show differently)
• Firmness or swelling
• Pain or discomfort

If you’re seeing any of these, escalate quickly. 

Bringing equipment and everyday care together: 

Most pressure injuries don’t occur because of a single cause. They develop when pressure, shear, moisture, nutrition and mobility challenges stack up. 

Key prevention actions from the 2025 International Guideline:

• Proper sitting posture
• Safe transfer techniques
• Active offloading of heels
• Moisture-barrier products
• Regular review of support surfaces
• Carer training and refreshers
• Early intervention plans when condition changes

Consistency is the most powerful prevention tool you have — and the right equipment setup supports that consistency across shifts. 

When to call in specialist help: 

The following guidelines call out groups who need experienced support.

• Bariatric individuals
• Those with spinal injuries
• Paediatric clients
• People who can’t reliably reposition
• Anyone with multiple comorbidities 

If you need a second opinion, our clinical advisors and Solutions Specialists can help interpret Waterlow scores, review care plans and recommend the safest, most effective equipment for your environment. 

Putting it all together: 

The Waterlow Score is a great starting point — but the impact comes from what you do next. When risk is identified early and paired with the right support surface, mobility routines and monitoring, you can dramatically reduce the chance of injury. 

Prevention is a partnership between your carers, your clinicians and an equipment provider who understands the full picture. The right gear supports better outcomes for your residents and your care teams. 

If you’d like support reviewing a resident’s pressure care plan or choosing equipment that aligns with the 2025 International Guidelines, we’re here to help.
