Braden Scale (Pressure Injury Risk)

Hospital admission pressure ulcer risk screening for all adult inpatients to guide mattress, positioning, and skin care decisions. This application is commonly used by professionals who need precise quantitative analysis to support decision-making, budgeting, and strategic planning in their respective fields

ICU pressure injury prevention bundle implementation — daily Braden scoring drives equipment prescribing and turning schedules. Industry practitioners rely on this calculation to benchmark performance, compare alternatives, and ensure compliance with established standards and regulatory requirements

Nursing home and care home resident assessment to prioritise pressure-redistributing equipment allocation. Academic researchers and students use this computation to validate theoretical models, complete coursework assignments, and develop deeper understanding of the underlying mathematical principles

How often should the Braden Scale be reassessed?

NICE recommends Braden (or equivalent) assessment on admission, within 6 hours of hospital admission for high-risk patients (elderly, immobile, post-operative), and reassessment every 24–48 hours or whenever clinical status changes significantly. In ICU, daily reassessment is standard. In nursing homes, weekly reassessment with every-shift skin inspection is typical. The process involves applying the underlying formula systematically to the given inputs.

What is the clinical threshold for the Braden Scale?

The original Braden validation used ≤16 as the threshold for risk in a hospital setting, with sensitivity 83% and specificity 64%. However, different thresholds apply in different settings: ≤18 is used for elderly care facilities; ≤16 for acute care; ≤13 for ICU; and ≤10 for critical care. NICE CG179 and many guidelines use ≤18 as the universal alert threshold requiring preventive intervention.

How does the Braden Scale compare to the Waterlow Score?

The Waterlow Score is the main alternative used in UK healthcare settings, while Braden is more commonly used in North America. Both assess similar domains of pressure ulcer risk but use different scoring conventions: Braden is reverse scored (lower = more risk; higher = less risk), while Waterlow is forward scored (higher = more risk). Both tools have comparable predictive validity. Some trusts use one; some use both.

What are the most important Braden subscales for predicting pressure ulcers?

Activity and mobility subscales are the strongest individual predictors of pressure ulcer development — immobile, bedfast patients are at dramatically higher risk. Moisture (particularly urinary incontinence causing skin maceration) and sensory perception (particularly pain insensitivity preventing self-repositioning) are next most important. Nutrition plays a significant role in wound healing capacity even if less predictive of ulcer development.

Does a high Braden score rule out pressure ulcer risk?

Not entirely. Braden predicts population-level risk but cannot guarantee individual patients are safe. Additional risk factors not captured by Braden include: peripheral vascular disease, dark skin (harder to detect early erythema), previous pressure ulcer history, anaemia, oedema, and critical illness medications (vasopressors causing peripheral vasoconstriction). Clinical skin inspection remains essential regardless of score.

What pressure redistribution devices are recommended at different risk levels?

At risk (≤18): high-density foam overlay on standard hospital mattress. Moderate risk (≤16): high-specification foam mattress (e.g., ROHO, Repose). High risk (≤13): dynamic air alternating pressure mattress (APM). Very high risk (≤10): continuous low-pressure or lateral rotation mattress; protective foam dressings on bony prominences; consider pressure-relieving operating table pads. This is an important consideration when working with braden pressure ulcer calculations in practical applications.

Is nutrition management part of pressure ulcer prevention?

Yes — malnutrition significantly impairs skin integrity and wound healing capacity. MUST (Malnutrition Universal Screening Tool) should be completed alongside Braden assessment. Patients at nutritional risk require dietitian referral. Protein supplementation (1.2–1.5 g/kg/day) is recommended for at-risk patients. Zinc, vitamin C, and arginine-containing supplements have evidence for wound healing in established pressure ulcers.

What are the most common pressure ulcer sites?

In supine patients: sacrum (35–40% of all pressure ulcers), heels (30%), occipital scalp (common in ICU). In sitting patients: ischial tuberosities, coccyx. In lateral lying: greater trochanter, medial knees, malleoli, ear. In prone-positioned patients (ICU): face, chest, genitalia. Heel pressure ulcers are often underestimated and should be prevented with heel offloading boots or foam wedges.
