Objective: To compare and analyze the clinical characteristics and strain distribution of community-acquired pneumonia (CAP) and hospital-acquired pneumonia (HAP) in children in Aba area

so as to provide theoretical reference for clinical treatment. Methods: Retrospective analysis was conducted on clinical data of 142 cases of children with CAP and 46 cases of children with HAP induced by other non-respiratory diseases in our hospital from Jan. 2016 to Jun. 2018

including clinical characteristics

length of stay

signs of admission

C-reactive protein (CRP)

procalcitonin (PCT)

white blood cell count (WBC) and other related laboratory indicators and the distribution of pathogens. Results: In terms of pneumonia-related signs at admission or clinical diagnosis

the CAP group (69.0%) showed more signs than the HAP group (47.8%). The cure time of pneumonia in the CAP group was shorter than that in the HAP group (t=2.53

P<0.05). Except for WBC (t=1.97

P<0.05)

there was no statistically significant difference in other related indicators. The main pathogens detected in the CAP group were Klebsiella pneumonia (18.25%)

Escherichia coli (15.08%)

Streptococcus pneumoniae (13.49%) and Pseudomonas aeruginosa (11.11%). The proportion of Acinetobacter baumannii in children in the HAP group was relatively high (17.65%). In the dynamic monitoring of CRP

the decrease in children in the CAP group was more significant

and the CRP level in the HAP group was higher than that in the CAP group on the 7th day of treatment (t=2.65

P<0.05). Conclusion: The characteristics of children infected with CAP and HAP are different

especially the difficult diagnosis and treatment of HAP

which should be paid more attention to.
