Accuracy: Raising the bar with unsurpassed accuracy of detecting early pressure ulcers

In clinical trial results presented at EPUAP (September 2014) and WoundsUK (November 2014), the SEM Scanner demonstrated exceptional levels of accuracy and a significant improvement in sensitivity and specificity over existing methods for risk assessment and visual assessment

  True Positive True Negative
Sacrum 91% 86%
Heel 83% 90%

Real Time Tissue Status: Results Achieved Quickly Empowers Early Detection

Easily fitting into clinical practice, scanner readings indicate in real time whether a pressure ulcer is forming. Earlier detection and earlier intervention leads to improved patient outcomes.  Time to learn the device averages 10 minutes.

Reliability: SEM Scanner users were able to generate reproducible readings of tissue status, regardless of prior level of experience.

Anatomical Site Operator Device
ICC 95% CI ICC 95% CI
Sternum 0.96 0.955–0.967 0.96 0.950–0.963
Sacrum 0.89 0.870–0.900 0.88 0.862–0.894
Right heel 0.85 0.834–0.872 0.84 0.814–0.857

* Interclass correlation coefficient (ICC) assesses the reliability across measurements by comparing variability. SEM Scanner demonstrated an ICC of >.85 suggesting that over 85% of variation is due to natural population variability not attributable to the device or operator.
