Matsumura et al reported a simple scale for predicting delayed intubation for a patient with inhalation injury. The authors are from Keio University, Tokyo Saisekai Central Hospital, Kawasaki Municipal Hospital and Saiseikai Utsunomiya Hospital in Japan,
PDI = prediction delayed intubation
Patient selection: burn patient with smoke inhalation
Parameters:
(1) signs related to the respiratory system (respiratory distress, hoarseness, dysphasia, stridor)
(2) presence of facial burn
(3) swelling noted on laryngoscopy

total score =
= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 6
• A score >= 4 had a sensitivity of 28% and specificity of 99% for intubation.
Performance:
• The area under the ROC curve is 0.90.
