Comparison of quick sequential organ failure assessment, reforming and quick sequential organ failure assessmentand CRB 65 scores for the prognosis of emergency patients with community acquired pneumonia

Abstract

Objective To explore the early predictive value of quick sequential organ failure assessment (qSOFA score), reforming and quick sequential organ failure assessment (qSOFA65 score) and CRB65 score in emergency community acquired pneumonia (CAP) patients. Methods According to the inclusion criteria, 520 cases were collected. qSOFA, qSOFA65, CRB65 scores were calculated and compared between the survival group and the death group, and between the non-machine ventilation (MV) group and the MV group. The receiver operating characteristic (ROC) curve was drawn and the prediction ability of the three scoring systems was compared by the area under the ROC curve (AUC). Results Of the 520 patients, 485 patients (93.3%) were alive, 35 patients (6.7%) died, 451 patients (86.7%) were non MV, and 69 patients (13.3%) were MV. The scores of qSOFA, qSOFA65 and CRB65 in survival group and death group, non MV group and MV group had significant differences (P CRB65 > qSOFA), and the optimal cut-off values were 1, 2, 1 score; AUC in the prediction of death in patients were 0.725, 0.772, 0.756 (qSOFA65 > CRB65 > qSOFA), and the optimal cut-off value was 1, 2, 2 scores. Conclusions qSOFA, qSOFA65 and CRB65 scores can predict early prognosis of CAP patients, and the qSOFA65 score is best. When qSOFA65 ≥ 2 scroes, patients with suspected CAP may have a poor prognosis.
