Abstract Objective To evaluate the predictive value of the predisposition insult response and organ failure (PIRO) scoring system for the non-invasive positive ventilation failure in emergency department patients with community acquired pneumonia (CAP). Methods A total of 122 patients with community-acquired pneumonia treated by NPPV in the emergency department were retrospectively analyzed. The PIRO, SMART-COP, CURB-65 and the minor criteria for severe CAP proposed by IDSA/ATS were calculated and compared between non-invasive positive ventilation success group and non-invasive ventilation failure group. The area under the receiver operating characteristic (ROC) curve was used to analyze the predictive value of the indicators above. The AUC of PIRO, SMART-COP, CURB-65 and IDSA/ATS score was analyzed by Ztest. Results There were significant differences in PIRO, SMART-COP, CURB-65 and the minor criteria of IDSA/ATS between non-invasive positive ventilation success group and non-invasive positive ventilation failure group (P<0.05). The AUC of PIRO, SMART-COP, CURB-65 and the minor criteria of IDSA/ATS score for predicting mechanical ventilation were 0.804, 0.746, 0.639 and 0.762, respectively. There was no significant difference between PIRO and SMART-COP, as well the IDSA/ATS minor criteria (P>0.05). But The AUC indicated that PIRO had better predictive values than CURB-65 (0.804 vs. 0.638, P<0.05). Conclusion Comparison of PIRO, SMART-COP, CURB-65 and IDSA/ATS Scores, PIRO score has predictive values for the non-invasive positive ventilation failure in the patients due to CAP in the emergency department. PIRO score has better predictive values than the CURB-65 score.
