A portable, advanced handheld skin imaging device being tested by Hamilton Health Sciences (HHS) is proving to be highly effective in spotting very early signs of pressure injuries in patients, even when damage is starting to form under the skin and can’t yet be seen by the naked eye.

A pressure injury, also called a pressure ulcer or bedsore, is damage to skin and tissue under a bony part of the body that has been pressed against a surface, such as a mattress or wheelchair. They happen when patients aren’t able to shift their weight, and the skin starts to break down.

Initial results from a four-month period, which included over 3,500 patient assessments, found that the MIMOSA Pro correctly identified the lack of early signs of pressure injuries in adult patients 91 per cent of the time, compared to 40 percent using the Braden Scale.

Pressure injuries are a challenge for hospitals, especially with higher-risk patients like older adults, and patients who are bedridden or in wheelchairs. Wounds from pressure injuries can lead to longer hospital stays, infection, amputation and even death.
