Hester Davis Scale Calculator

Formula

To calculate the Hester Davis Scale Score ( $HDS$ ):

$HDS = MS + M + A + N + FS$

Where:

$HDS$ is the Hester Davis Scale Score
$MS$ is the Mental Status (0-2 points)
$M$ is the Mobility (0-3 points)
$A$ is the Activity (0-3 points)
$N$ is the Nutrition (0-3 points)
$FS$ is the Friction and Shear (0-3 points)

What is the Hester Davis Scale?

The Hester Davis Scale is a tool used by healthcare professionals to assess the risk of pressure ulcers in patients. It evaluates five key factors that contribute to skin breakdown and ulcer formation. A higher score indicates a greater risk of developing pressure ulcers, which can then inform the level of care and preventative measures needed for the patient.

Example Calculation 1

Let's assume the following values:

Mental Status ( $MS$ ) = 1
Mobility ( $M$ ) = 2
Activity ( $A$ ) = 1
Nutrition ( $N$ ) = 2
Friction and Shear ( $FS$ ) = 1

Using the formula:

$HDS = 1 + 2 + 1 + 2 + 1 = 7$

The Hester Davis Scale Score (HDS) is 7.

Example Calculation 2

Let's assume the following values:

Mental Status ( $MS$ ) = 2
Mobility ( $M$ ) = 3
Activity ( $A$ ) = 2
Nutrition ( $N$ ) = 3
Friction and Shear ( $FS$ ) = 3

Using the formula:

$HDS = 2 + 3 + 2 + 3 + 3 = 13$

The Hester Davis Scale Score (HDS) is 13.
