Triage and scoring systems have been developed to differentiate critical patients from others and to ensure early intervention in crowded emergency departments. We aimed to determine the utility of the perfusion index in the triage of patients, and its association with mortality in comparison and combination with the Modified Early Warning score. This was a single-center and prospective study. The study included patients who received yellow or red triage code in emergency department. The modified Early Warning scores were calculated from patients data. The perfusion index value was measured using a Masimo® device with probe. The outcomes of the patients and one-month mortality were recorded. 397 patients were included in the study. Mean perfusion index and Modified Early Warning score was 4.05 (± 2.67) and 1.99, respectively in patients discharged from the emergency department, 1.12 (± 0.97) and 7.5, respectively in patients deceased at the emergency department. Finally, the Modified Early Warning score was added to the perfusion index and the effect of the created model on mortality was evaluated. In this case, the new model had an accurate classification rate of 91.7%, with a sensitivity of 98.6% and a specificity of 45.1%. Nagelkerke’s R2 of 0.434 suggested that the model was effective in explaining the dependent variable (mortality) at a rate of 43.4%. It would be possible to make early decisions on intervention and prevent mortality since the combined use of perfusion index and Modified Early Warning score provide higher reliability in identifying critical patients.
