Treat Raised SEM Deltas (Δ) to prevent
broken skin PI/U and DTIs

The Status Quo

PUs are frequent, serious and expensive wounds^1,2,3,4

PUs occur in hospital, hospice and community settings

Risk assessments are subjective and not anatomy specific⁵

Current standard of care (visual and tactile skin assessments) cannot detect pre ulceration skin changes which can then progress to more severe broken skin PUs

Skin assessments only trigger interventions after skin redness is visible

Current standard of care fails patients with dark skin tone, as redness is not visible⁶

Changing The Status Quo

Biocapacitance

Electrical property of tissue; a biophysical measure of changes in localized oedema also known as sub-epidermal moisture (SEM)

Tissue biocapacitance increases when SEM increases

As a result of a localized inflammatory response triggered due to a developing PU; this is non-visible tissue damage⁷

SEM is one of the earliest indicators of a developing PU that is still microscopic

Concept of SEM is now proven in the published literature:

SEM can now be accurately measured via the Provizio® SEM Scanner^8,9
Raised SEM is proven to indicate microscopic pre ulcer skin changes
Raised SEM should be regarded as a condition that should be treated
Treat a raised SEM delta as per a stage one PU
Monitor the impact of your treatment actions ……and review the care plan
