Positive Blood Culture Profile Through Systematic Review

Objective: This study aimed to gather data on the prevalence of microorganisms in the bloodstream. Theoretical Framework: In this topic, the fundamental theoretical bases for research on Bloodstream Infections (BSI) are presented. Epidemiological, microbiological and clinical aspects stand out, including incidence, microorganisms involved, antimicrobial resistance and clinical and economic impacts. Furthermore, the importance of systematic reviews in the synthesis and critical evaluation of available evidence is discussed. Method: This study was carried out based on a systematic bibliographic review, where data from articles published in scientific journals in the Google Scholar, Lilacs and PubMed databases were collected and selected, from 2012 to 2019. Results and Discussion: In the various articles analyzed in this review, 52 different microorganisms were found. Staphylococcus aureus and Klebsiella pneumoniae are the most prevalent in the group of microorganisms observed in positive blood cultures. Regarding gender, it was found that of the 2,210 samples corresponding to the total number of positive blood cultures in the 21 articles analyzed, 36% were positive for males and 64% for females. Research Implications: Highlights the importance of surveillance and effective control of Bloodstream Infections, especially considering the prevalence of microorganisms such as Staphylococcus aureus and Klebsiella pneumoniae, influencing health practices, public policies and hospital protocols. Originality/Value: This study contributes to the literature by gathering data on the prevalence of microorganisms in Bloodstream Infections, providing essential insights to improve prevention and control practices, directly impacting public health and patient safety.
