Non-Invasive Testing to Evaluate Wound Healing in Diabetes

Summary

Normal group: We will collect normative data from healthy individuals to include baseline data, screening, and images. Up to 500 people will be enrolled and can include normal healthy volunteers, staff and students/trainees. Data will be collected one time with no follow up. Patient group: We will prospectively collect data using one instrument (camera) (SnapshotNIR, Kent Imaging, Calgary, Alberta, Canada). We will collect non-contact imaging data before surgeries, during surgeries (if feasible), and during follow-up clinic visits. We will collect vascular data, demographic medical history, wound characteristics and measurements, frequency of debridement, off-loading, and clinic visits from existing medical records. We will collect lab data such as cultures glycosylated hemoglobin, hemoglobin and hematocrit, ESR, CRP and eGFR obtained per standard of care. Imaging with this device is research-only.
