The Braden Scale: Scoring Pressure Injury Risk, and Actually Acting on It
Six subscales, a total from 6 to 23, and a lower number meaning higher risk. How each subscale is scored, what the risk bands mean, and the part that matters most — turning a number into the specific interventions it points at.

Pressure injuries are among the clearest examples of harm that nursing care prevents outright. They’re also among the most reliably predictable, which is why a risk score exists at all.
The Braden Scale is the most widely used of those scores. It works — but only when the number leads somewhere. A Braden charted on admission and never converted into an intervention is documentation, not prevention.
The six subscales
Each is scored 1 to 4, except friction and shear which runs 1 to 3. Totals range from 6 to 23, and — counterintuitively — lower means higher risk.
| Subscale | What it asks | Range |
|---|---|---|
| Sensory perception | Can they feel and report discomfort? | 1–4 |
| Moisture | How wet is the skin kept? | 1–4 |
| Activity | How much do they move about? | 1–4 |
| Mobility | Can they reposition themselves? | 1–4 |
| Nutrition | What are they actually eating? | 1–4 |
| Friction & shear | Do they drag across surfaces when moved? | 1–3 |
Score what you observe, not what's convenient
Braden scores drift upward under time pressure — a patient who “seems okay” gets 3s across the board. The subscales are behavioural and observable: watch a transfer, look under the gown, check what came back on the meal tray. An inflated score removes the very interventions the patient needs, and it does it silently.
The risk bands
Thresholds vary a little between institutions, so follow your facility’s protocol. Commonly:
| Total | Risk |
|---|---|
| 19–23 | Not at risk |
| 15–18 | Mild |
| 13–14 | Moderate |
| 10–12 | High |
| 9 or below | Very high |
The part that actually matters: subscale-driven care
Here’s the most useful thing to understand about the Braden — the total tells you how worried to be, but the subscales tell you what to do. Two patients can both score 13 for completely different reasons and need completely different plans.
- Low sensory perception — they won’t tell you it hurts, so the schedule has to do the work. Scheduled repositioning, deliberate inspection of pressure points, and extra attention to anything they can’t feel: heels, sacrum, under devices.
- Low moisture — incontinence, sweat, or drainage is macerating skin. Barrier products, absorbent surfaces that wick rather than trap, and prompt changes. Moisture-damaged skin breaks down under far less pressure.
- Low activity or mobility — the core of most plans. A repositioning schedule that’s actually followed, pressure-redistributing surfaces, heel offloading, and getting them up when it’s safe. Mobility is the subscale most responsive to nursing effort.
- Low nutrition — protein and calories are what tissue repairs with. This is a dietitian referral, not a note. Track intake honestly.
- Low friction and shear — the fix is technique and equipment: lift rather than drag, use a slide sheet, limit head-of-bed elevation where the clinical picture allows, because a patient sliding down the bed is shearing every time.
The score is not the assessment
Braden predicts risk; it does not detect injury. A skin inspection is a separate act, and a good score never substitutes for looking. Check the sacrum, heels, and under every device — oxygen tubing, cervical collars, compression sleeves, pulse oximetry probes. Device-related pressure injuries are common, easily missed, and entirely preventable.
Timing and reassessment
Score on admission, and then on your facility’s schedule — often each shift in higher-acuity settings and less often in stable ones. What matters more than the interval is rescoring when the patient changes: after surgery, a new vasopressor, sedation, a fall in intake, new incontinence, or a transfer between units.
Risk isn’t static. A patient admitted independently ambulant and scoring 20 can be a 12 three days later, and nobody notices unless somebody rescores.
The bottom line
The Braden is a good scale used carelessly more often than not. Score it honestly, read the subscales rather than only the total, and let each low subscale name its own intervention. The number’s only purpose is to change what you do next.
Try it
Score all six subscales with the Braden Scale calculator — it totals them and flags the risk band.
Keep going
For the patient whose vital signs are drifting rather than their skin, early warning scores covers the other end of proactive monitoring.
