Wound Dressing Frequency Calculator

Work out wound dressing frequency instantly with clear inputs, formula shown and shareable results.

About Wound Dressing Frequency Calculator

Adjusts the dressing's wear time for exudate level and converts it into changes per week and the dressings needed over the planning period.

Formula

Change frequency

Interval = dressing wear time x exudate factor (0.5 high, 1.0 moderate, 1.5 low); changes per week = 7 / interval

Worked example

With the default values below, Wound Dressing Frequency Calculator returns Dressing changes per week of 2.33. Change any input above and every figure here is recalculated in your browser.

Inputs used

Results

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or fees or charges into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

Frequently Asked Questions

Why not change dressings daily?

Unnecessary changes cool the wound, disturb granulation tissue and increase cost and infection risk.

What forces an earlier change?

Strike-through of exudate, dressing lift, odour, pain or suspected infection.
