OBJECTIVES@#To study the consistency between nasopharyngeal aspirates (NPA) and
bronchoalveolar lavage fluid (BALF) in pathogen
detection in
children with
pneumonia @*
METHODS @#A retrospective
analysis was performed on the data of pathogens detected in 533
children with
pneumonia from February 2017 to March 2020. The paired McNemar's test was used to compare the difference in pathogen
detection between NPA and BALF groups. The @*RESULTS@#NPA had a
sensitivity of 28%, a
specificity of 74%, a
positive predictive value of 14%, and a
negative predictive value of 91% in detecting
bacteria , and a @*CONCLUSIONS@#There is poor consistency between NPA and BALF in the
detection of
bacteria and
viruses , and clinicians should be cautious in diagnosing lower
respiratory tract infection based on
bacteria or
viruses detected in NPA. There is moderate consistency between NPA and BALF in the
detection of
