| Abstract |
The workup and interpretation of tracheal aspirate (TA) cultures remains controversial. The Geckler (Ge) classification and the Miller-Jones (M-J) classification were typical method for evaluating sputum quality, and were recommended in some guidelines. Few studies have evaluated the convenience of the TA specimens in diagnosing pediatric bacterial pneumonia. A retrospective analysis was conducted at a children's hospital in Aichi to reveal the sensitivity and specificity analysis of the Ge and M-J classification criteria for diagnosing bacterial pneumonia. Patients admitted to the intensive care unit between 2016 and 2021, and provided TA specimens were enrolled. Bacterial pneumonia was defined as the occurrence of consolidation on chest radiography, a positive sputum culture, and antibiotic treatment for at least seven days. During the study period, 383 TA specimens (230 patients) were included in the analysis, 18 of which satisfied the definition of bacterial pneumonia. The sensitivity and specificity of the Ge classification criteria for bacterial pneumonia were 88.9% and 39.5%, respectively. And Ge classification had a high negative predictive value, as 98.6%. Whereas, the sensitivity and specificity of the M-J classification criteria were 50.0% and 87.1%. The Ge classification had a high sensitivity and negative predictive value, and could be useful in excluding bacterial pneumonia if not being in Geckler group 4 or 5. On the other hand, the M-J classification had insufficient sensitivity and specificity to diagnose bacterial pneumonia. |
