Impacto del SARS-CoV-2 en el diagnóstico de bacteriemia comunitaria en un hospital terciario

OBJECTIVE: We carry out an analysis of the bacteremia diagnosed in the Emergency Department during 2020, coinciding with the period of the pandemic. METHOD: We performed a retrospective analysis from March 4, 2020 to December 31, 2020. RESULTS: The number of patients who went to the Emergency Department during the study period and the number of extracted blood cultures decreased by 46.79% and 35.7% compared to the same period in 2019 (p <0.05). 320 bacteremia occurred while 507 occurred in 2019, assuming a decrease of 36.8% (p <0.05). The positivity rate of blood cultures was 7.09% in 2020 and 7.23% in 2019 and the contamination rate was 7.07 % in 2020 and 5.67% in 2019. The most frequently isolated microorganism was Escherichia coli, followed by Staphylococcus aureus and Klebsiella pneumoniae. A 6.62% of the isolated E. coli were carriers of extended-spectrum beta-lactamases (ESBL). The percentage of methicillin-resistant S. aureus was 12.9 % and that of K. pneumoniae ESBL was 11.54%. CONCLUSION: During the SARS-CoV-2 pandemic there has been a decrease in the number of bacteremia diagnoses, it is possible that attention was focused especially on COVID, forgetting other diseases, such as bacteremia.
