Infrared thermography is a timely and reliable method for nursing practitioners in pressure injury risk assessment.
Fuman Cai, 2020. Application of infrared thermography in the early warning of pressure injury: a prospective observational study
In the aforementioned study, 415 patients admitted to the adult intensive care units were enrolled by a convenience sampling method, and they received a follow-up monitoring for 10 days.
The risk of pressure injury was assessed via Braden scale, and thermal images of the sacral area were obtained by infrared thermal imager once a day.
The IRT-based model can objectively and accurately detect pressure injuries one day before visual detection.
A recent study from China included 263 patients who were screened for pressure injuries in the sacral region. The study showed that the ability of infrared thermography to detect pressure injuries was better than that of the other methods used.
