Background: community-acquired pneumonia is a major health problem worldwide, in Cuba and in the province of Cienfuegos. Objective: to report the results of blood cultures performed at hospital admission in patients with community-acquired pneumonia. Methods: a prospective descriptive study was conducted in the Gustavo Aldereguía Lima Hospital in Cienfuegos, during the second half of 2012. It included 52 patients with community-acquired pneumonia who underwent blood culture at their admission to the hospital. Results: only five patients (9.6% of the cases) had a positive test result; Streptococcus pneumoniae was isolated from only one positive culture; Staphylococcus aureus and Klebsiella pneumoniae were isolated from the rest. Conclusions: the percentage obtained in this study confirms the low diagnostic yield of blood cultures performed at admission in patients with community-acquired pneumonia; the low isolation rate of S. pneumoniae in our study was also significant.
