Summary

In Canada, the age-standardized prevalence of diabetes is on the rise (increasing from 3.3% in 1998/99 to 5.6% in 2008/2009 Public Health Agency of Canada (July 2011)) and is almost 1 in 10 globally. One of the most devastating complications of diabetes is the loss of a limb, (also known as lower extremity amputation, or LEA) due to complications resulting from a diabetic foot ulcer (DFU). Diabetics have a lifetime risk of 15-25% of developing a DFU1, which can lead to significant decreases in the quality of life, limitations in mobility, function and independence, and increased chance of depression and anxiety. In addition, diabetics post-LEA have high rates of mortality, with 30% dying in the first year post LEA and 70% at 5 years (more than the lifetime risk of dying from cancers). What differentiates a DFU that heals and one that progresses to LEA is often the vascularity of the limb; the diabetic lower extremity often becomes ischemic due to the vascular sequelae that are a common complication of diabetes, which hampers wound closure and immune clearance of wound-associated infections. Understanding limb oxygenation can direct treatment of a DFU, which may require limb revascularization to heal.

Conditions

Interventions

DEVICE

MIMOSA Imager

The MultIspectral MObile tiSsue Assessment (MIMOSA) Imager acquires digital images to calculate anatomical details of chronic wounds (e.g. diameter, surface area, and perimeter). The device can be worn from a lanyard, and clips onto a smartphone, using natural ambient lighting to capture images of a wound. The MIMOSA also uses up to 6 near-infrared LEDs to illuminate tissue with different wavelengths of light to assess tissue oxygenation.

DEVICE

Kent Camera

The Food and Drug Administration (FDA) has previously approved a near-infrared device called the Kent camera for the assessment of tissue oxygenation.
