The Challenge of Predicting Pressure Ulcers in Critically Ill Patients. A Multicenter Cohort Study.

The original Braden scale measured at ICU admission is a valuable tool for pressure ulcer prediction, although it is not accurate for severely ill patients. To overcome the limitations of the original scale, we derived a modified score with better performance, which may identify high-risk ICU patients and support target interventions. External validation of the proposed clinical prediction score is needed.
