Long-wave infrared imaging can be used to identify skin temperature changes associated with
underlying tissue changes. We want to determine if the use of Long Wave infrared Imaging is
as effective as the Braden Score in predicting nosocomial pressure ulcers.
The Trillennium Medical Imaging system will be used to gather skin temperature data on 100
subjects. The subjects will be enrolled from Duke North floors 8100 or 8300 in a
prospective controlled trial. All eligible patients who have signed a consent form will be
assessed using the Long Wave Infrared imaging.
Subjects eligible for this study who have signed a consent form will be scanned on bilateral
heels and sacrum. Subjects with ulcers on those areas will also be scanned due to the fact
that they are at a high risk of developing additional pressure ulcers. The intent is not to
capture images of the existing ulcer, but to focus on areas that could potentially develop
into additional pressure ulcers. The subjects who already have an ulcer will only be
scanned on non ulcerated tissue. The areas of interest must be off-loaded for 3 minutes
from any pressure in order to acclimate to ambient temperature. The device will be held
approximately 36 inches from the area of interest in order to obtain an image. The subjects
will be assessed within 24 hours of admission and every 24 hours until discharge or they
develop a pressure ulcer. The subject's routinely recorded Braden scores (By on the floor
nursing staff) will also be captured in order to effectively compare the effectiveness of
the Imaging system. The nurse conducting the imaging will also record a Braden score.
All subjects will be included in the trial unless they refuse to participate or are
incapacitated to the degree that imaging becomes unreasonable.
