Aloweni et al reported a score for predicting a hospital-acquired pressure ulcer in a surgical patient. This can help to identify a patient who may benefit from more aggressive preventive measures. The authors are from Singapore General Hospital and Duke-NUS Medical School in Singapore.
Patient selection: hospitalized surgical patient
Parameters:
(1) age of the patient in years
(2) sex
(3) ASA grade
(4) body mass index (BMI) in kg per square meter
(5) preoperative Braden score, from 6 to 23
(6) anemia
(7) respiratory disease
(8) hypertension

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 14
• The higher the score the greater the risk of pressure ulcer.

Performance:
• The area under the ROC curve is 0.78.
