Improving the detection of pressure ulcers using the TMI ImageMed system.

OBJECTIVE

The aim of the study was to evaluate a novel infrared imaging device coupled with an intelligent software interface that may provide a more objective means of identifying anatomical sites at risk for pressure ulcer (PrU) development as compared with the Braden Scale for Predicting Pressure Sore Risk.

DESIGN

Repeated-measures design.

SETTING

Duke University Medical Center.

PARTICIPANTS

One hundred patients admitted to a medical unit at risk for PrUs.

MAIN

RESULTS

Only 5 participants developed early stage PrUs (Stages I and II). However, the infrared imaging device not only predicted all 5 participants to be at risk, but also predicted the anatomical location where the ulcer would develop. The Braden Scale correctly identified 3 of 5 participants who developed PrUs. It was also determined that a temperature variance of 1.5° C was able to accurately predict PrU development.

CONCLUSION

Infrared imaging using intelligent software may become a promising, objective method for identifying incipient PrUs and provide clinicians with specific anatomical locations for increased preventive interventions.
