Introduction

The Braden Scale Calculator helps you check a patient's risk of getting a pressure ulcer (also called a bed sore). Pressure ulcers form when skin stays pressed against a bed or chair for too long and blood cannot reach it. They can start in just a few hours.

This calculator uses the Braden Scale, which nurses and doctors have used since 1987. You score six things: sensory perception, moisture, activity, mobility, nutrition, and friction and shear. Each one gets 1 to 4 points, except friction and shear, which gets 1 to 3 points.

The calculator adds your answers into one total score from 6 to 23. A lower score means higher risk. The result shows the total, the risk level, a score gauge, a full breakdown of each part, and the steps used to get the answer.

Use it at admission and again as a patient's health changes. It shows which area is weakest, so you know where to act first, like turning the patient more often, keeping skin dry, or improving meals. This calculator supports your judgment. It does not replace a full skin check by a trained health worker.

How to use our Braden Scale Calculator

Pick one option in each of the six sections below. The calculator adds your picks and shows a total Braden score out of 23, the pressure ulcer risk level, a score gauge, a breakdown table, and a step-by-step solution.

Sensory Perception (1 to 4 points): Choose how well the patient feels and reports pain or discomfort. Pick a low score if the patient does not respond to pain, and a high score if they feel and speak about pain with no problem.

Moisture (1 to 4 points): Choose how wet the patient's skin stays from sweat, urine, or drainage. Pick a low score if the skin is damp almost all the time, and a high score if the skin is usually dry.

Activity (1 to 4 points): Choose how much the patient moves around each day. Pick a low score if they stay in bed, and a high score if they walk outside the room at least twice a day.

Mobility (1 to 4 points): Choose how well the patient can change body or limb position on their own. Pick a low score if they cannot shift at all without help, and a high score if they move freely and often.

Nutrition (1 to 4 points): Choose how much food and protein the patient eats each day. Pick a low score for poor intake or NPO status, and a high score if they eat most of every meal.

Friction and Shear (1 to 3 points): Choose how much the patient's skin rubs or drags during moves. Pick a low score if they slide down in bed and need lots of help, and a high score if they lift up on their own and hold good position.

What Is the Braden Scale?

The Braden Scale is a tool nurses and doctors use to check how likely a patient is to get a pressure sore. Pressure sores are also called bedsores, pressure ulcers, or pressure injuries. They form when skin and the tissue under it get squeezed for too long, often over bony spots like the tailbone, hips, heels, and elbows. Blood cannot reach the area, so the skin breaks down.

Barbara Braden and Nancy Bergstrom built the scale in 1987. It is still one of the most used pressure sore risk tools in hospitals and nursing homes around the world.

The Six Areas It Scores

The scale looks at six things that raise or lower skin risk:

  • Sensory perception: can the person feel and report pain or pressure?
  • Moisture: how wet is the skin from sweat, urine, or stool?
  • Activity: how much does the person walk or move around?
  • Mobility: can the person shift their body position in bed or a chair?
  • Nutrition: how much food and protein does the person eat?
  • Friction and shear: does the skin drag or slide against sheets when moving?

Five areas are scored 1 to 4. Friction and shear is scored 1 to 3. Add them up and the total falls between 6 and 23. A lower score means higher risk.

What the Score Means

  • 19 to 23: No risk found
  • 15 to 18: Mild risk
  • 13 to 14: Moderate risk
  • 10 to 12: High risk
  • 6 to 9: Very high risk

Why It Matters

Pressure sores hurt, take a long time to heal, and can lead to serious infections. Catching risk early is much easier than treating an open wound. The Braden Scale helps care teams pick the right steps before skin breaks down, such as turning the patient every two hours, using a special mattress or cushion, keeping skin clean and dry, adding padding at the heels, and improving food and fluid intake.

How It Is Used in Care

Staff usually score a patient when they first come in, then again every day or two, and any time their health changes. A single low subscale tells you as much as the total does. For example, a low nutrition score points to a diet plan, while a low moisture score points to better incontinence care.

The Braden Scale is a guide, not a diagnosis. It does not replace a full skin check or the judgment of a trained nurse or doctor. Always pair the score with a head-to-toe look at the skin.

Frequently asked questions

Is a high Braden score good or bad?

A high Braden score is good. It means lower risk of pressure sores. The scale runs from 6 to 23. A score of 19 or more means no risk was found. A score of 9 or less means very high risk. So the lower the number, the more the skin is in danger.

What Braden score means a patient needs a prevention plan?

Most hospitals start prevention steps at 18 or below. That is the mild risk line. Steps get stronger as the score drops:

  • 15 to 18: turn often, keep skin dry, protect heels
  • 13 to 14: add a pressure-reducing mattress or cushion
  • 12 or less: turn every 2 hours, use a special support surface, call a wound nurse

How often should the Braden Scale be repeated?

Score the patient when they first come in, usually within 8 hours. After that:

  • Hospital wards: once a day
  • ICU: every shift
  • Nursing homes: weekly for the first month, then monthly or quarterly
  • Home care: at every visit

Always score again if the patient gets worse, has surgery, or stops eating.

What is the difference between the Activity and Mobility subscales?

They sound alike but measure different things.

  • Activity is how much the person gets up and moves around the room or hallway.
  • Mobility is how well the person shifts their own body while in bed or a chair.

A person can be stuck in bed (low activity) but still roll over on their own (better mobility).

What is the difference between friction and shear?

Friction is skin rubbing across a sheet, like when heels drag. It scrapes the top layer of skin.

Shear is when the skin stays put but the bone and tissue under it slide, like when a patient slips down in a raised bed. Shear tears blood vessels deep inside and does more damage than friction.

How fast can a pressure sore form?

Damage can start in as little as 2 to 6 hours of steady pressure. Some deep tissue injuries begin under the skin before anything shows on the surface. That is why turning every two hours is the standard rule for people who cannot move on their own.

Where do pressure sores form most often?

They form over bony spots with little fat padding. The most common places are:

  • Tailbone and sacrum (lower back)
  • Heels
  • Hips
  • Elbows
  • Shoulder blades
  • Back of the head
  • Ears (from oxygen tubing)

The sacrum and heels together cause most pressure sores in hospitals.

What scale is used for pressure sore risk in children?

Children use the Braden Q Scale. It keeps the six original areas and adds a seventh: tissue perfusion and oxygenation. Each item scores 1 to 4, so totals run from 7 to 28. A score of 16 or less means the child is at risk. It is made for kids from 21 days to 8 years old.

How is the Braden Scale different from the Norton Scale?

Both predict pressure sore risk, but they check different things.

  • Braden: six areas, total 6 to 23, includes nutrition, moisture, and friction/shear.
  • Norton: five areas, total 5 to 20, includes physical and mental condition and incontinence.

Braden is more common in the United States. Norton is older and simpler, and is still used in parts of Europe.

Can a patient with a good Braden score still get a pressure sore?

Yes. The scale is a guide, not a promise. It does not count age, low blood flow, diabetes, fever, low blood pressure, or medical devices like oxygen tubes and casts. Always do a head-to-toe skin check along with the score.

What counts as a serving of protein for the nutrition score?

One serving is about 2 to 3 ounces of meat, fish, or poultry, one egg, one cup of milk, or a slice of cheese. Count how many the patient eats in a day:

  • 2 or fewer: very poor (1 point)
  • 3: probably inadequate (2 points)
  • 4: adequate (3 points)
  • 4 or more plus snacks: excellent (4 points)

What is the lowest score a person can get on the Braden Scale?

The lowest possible total is 6. That happens when all six areas score 1 point each. It means the patient cannot feel pain, has wet skin, stays in bed, cannot move, eats very little, and slides during every move. This is very high risk and needs urgent prevention.

Does one low subscale matter if the total score looks fine?

Yes. A single score of 1 or 2 in any area points to a real problem, even when the total sits in a safe band. For example, a total of 19 with a moisture score of 1 still needs better incontinence care. Treat the weak area, not just the total.
