- Abstract: Objective To explore the value of lung ultrasound combined with white blood cells (WBC) and procalcitonin (PCT) in diagnosing pediatric community- and hospital-acquired pneumonia. Methods A total of 153 pediatric patients with suspected community- and hospital-acquired pneumonia were enrolled. According to the final clinical diagnosis results, they were divided into pneumonia group (n=78) and non-pneumonia group (n=75). All patients underwent lung ultrasound, WBC and PCT examinations. The sensitivity, specificity, accuracy, positive predictive value, negative predictive value and Kappa value of lung ultrasound alone and lung ultrasound combined with WBC and PCT in the diagnosis of acquired pneumonia were compared. According to the severity of pneumonia in pneumonia group, pediatric patients were divided into severe group (n=36) and non-severe group (n=42) and the diagnostic value of WBC and PCT in the severity of acquired pneumonia was analyzed by ROC curves. Results The sensitivity, specificity, accuracy, positive predictive value, negative predictive value and Kappa value of lung ultrasound combined with WBC and PCT in diagnosing acquired pneumonia were significantly higher than those of lung ultrasound alone, with statistical significance (96.2% vs 71.8%, 97.3% vs 69.3%, 96.7% vs 70.6%, 97.4% vs 70.9%, 96.1% vs 82.9%, and 0.935 vs 0.411, respectively all P<0.05). The results of ROC curve analysis showed that WBC, PCT and their combination were of certain diagnostic value for the severity of acquired pneumonia (P<0.05), and that the AUC of WBC combined with PCT was greater than that of WBC alone and PCT alone (P<0.05). Conclusion Lung ultrasound combined with WBC and PCT can improve the diagnostic efficiency of pediatric community- and hospital-acquired pneumonia, and meanwhile it is beneficial to the diagnosis of disease severity.
