Study Population
The SEM200-008 (008) clinical study was a prospective, blinded study designed to evaluate the
SEM Scanner relative to the current Standard of Care, Visual Skin Assessment (VSA), for
identifying patients with skin and tissue at increased risk of developing pressure ulcers at the
heels or sacrum. In the 008 Study there were 12 unique clinical-trial sites in the United States
and United Kingdom that were included in the study. Each had their own Principal Investigator.
Subjects in the 008-study received standard-of-care interventions for pressure ulcer prevention
and management. These subjects were at varying risk for developing pressure ulcers (PUs) (as
defined by current risk assessment tools) and thus interventions were given.
According to the study protocol’s inclusion criteria, these patients were defined as being “at
ris
k” if they met one of the following criteria:
•
PU Risk Score
–
Braden < 15; Waterlow ≥ 10; or Norton ≤ 18;
•
Poor mobility; e.g., Braden mobility subscore ≤2; Waterlow mobility subscore >2;
Norton mobility subscore ≤2; or poor mobility according to
clinical judgment (chair- or
bed-bound);
•
Poor nutrition; e.g., Braden nutrition subscore ≤2; Waterlow nutrition subscore >2; or
other indicator of poor nutrition; and/or
•
Medical procedure (e.g., surgery, x-ray, etc.) involving immobility and inability to change
position lasting 4 hours or longer.
Specifically, 182 patients were listed as Intent to Treat (ITT). Of those, 170 Patients were
included in the sensitivity and specificity calculations with 48 pressure ulcers forming across 36
Patients.
Within the 12 sites included in the study, the trials were completed in:
1.
Orthopaedic Trauma: 14% (n=26 subjects)
2.
Medical Surgery: 27% (n=50 subjects)
3.
Long Term Care: 32% (n=58 subjects)
4.
ICU: 9% (n=17 subjects)
5.
Rehab: 4% (n=7 subjects)
6.
Neurologic Care: 8% (n=15 subjects)
7.
Other/Mixed: 5% (n=9 subjects)
