Antimicrobial resistance and pathogen distribution in hospitalized burn patients: A multicenter study in Southeast China

Burn infections pose a serious obstacle to recovery. To investigate and analyze the antimicrobial resistance and distribution of pathogenic bacteria among hospitalized burn patients. A 3-year retrospective study was conducted in the southeast of China. The electronic medical records system was used to collect all clinical data on 1449 hospitalized patients from Fujian Medical University Union Hospital, the 180th Hospital of Chinese People's Liberation Army (PLA), the 92nd Hospital of PLA, and the First Hospital of Longyan City. A total of 1891 strains of pathogenic bacteria were detected from 3835 clinical specimens, and the total detection rate was 49.3% (1891/3835). The main pathogens were gram-negative bacteria (1089 strains; 57.6%), followed by gram-positive bacteria (689 strains; 36.4%), and fungi (113 strains; 6.0%). The predominant five bacteria were Staphylococcus aureus (19.0%), Acinetobacter baumannii (17.6%), Pseudomonas aeruginosa (16.7%), Klebsiella pneumoniae (7.4%), and Enterococcus faecalis (4.5%). Methicillin-resistant Staphylococcus aureus (MRSA) accounted for 74.1% (265/359) of S aureus isolates. Staphylococcus epidermidis accounted for 40.6% (69/170) of coagulase-negative staphylococcal isolates, 72.5% (50/69) of which were methicillin-resistant Staphylococcus epidermidis (MRSE). Both MRSA and MRSE were 100% resistant to penicillin and ampicillin. A baumannii was the most commonly isolated strain of gram-negative bacteria with 100% resistance to ampicill...
