“…Staphylococcus aureus, Pseudomonas aeruginosa y especies de enterobacterias son los microorganismos más frecuentes.

Introduction. Infections due to bacteremia in burn patients are a common cause of complications and an extended length of stay. Knowing causative microorganisms and identifying associated risk factors allow to reduce infectious complications, morbidity, mortality, and health care expenditure. This study assesses the extent of the association between risk factors and bacteremia in burn patients and identifies the most common microorganisms found in blood cultures. Population and methods. Case-control study conducted at the Burn Intensive Care Unit of Hospital de Pediatría S.A.M.I.C. "Prof. Dr. Juan P.Garrahan" between June 1 st , 2014 and September 30 th , 2019 in patients with bacteremia events and a positive blood culture (cases) and patients with a negative blood culture (controls). Results. During the study period, 29 cases of bacteremia were identified. The median length of stay at the time of bacteremia was 23 days. The most commonly identified microorganism was Pseudomonas (7 cases). The only risk factor that showed a significant association was the presence of a central venous line for 7 days or more (OR: 3.18; 95 % confidence interval: 1.20-8.38). The overall mortality rate was 9.1%; 13.8% for cases and 3.4% for controls. Conclusions. Central venous lines for more than 7 days are an independent risk factor for bacteremia in critically ill burn children. No statistically significant association was established with other studied risk factors. Pseudomonas, Acinetobacter, and coagulase-negative Staphylococcus were the most common microorganisms found in bacteremia.

Background: Epidemiology and risk factors for bacteremia in pediatric and adolescent patients have not been fully elucidated. Objective: The purpose of this study was to identify primary causative agents of bacteremia in pediatric and adolescent patients and associated risk factors. We hypothesized that these would be different than those seen in adults. Patients and Methods: This retrospective cohort, epidemiologic evaluation included patients admitted to a tertiary referral center from January 01, 2013, to December 31, 2015. Patients <18 years old with a confirmed positive blood culture were included; the first positive culture per organism per patient was analyzed. The primary outcome was to determine the most frequent causative organisms of bacteremia; the secondary outcome was an evaluation of risk factors for acquiring staphylococcal bacteremia. Results: A total of 913 isolates were evaluated, including 92 unique organisms. The most frequently identified were Staphylococcus epidermidis (238/913, 26.1%), followed by Staphylococcus aureus (136/913, 14.9%). Methicillin resistance was observed in 60.3% of S aureus. Two hundred thirty-six patients were included in the risk factor analysis. Prematurity, previous antibiotics, and intubation/ventilation were more likely associated with S epidermidis ( P < .001, P < .001, and P = .032, respectively). Patients with a recent or previous hospitalization and those with dermatitis/eczema were statistically more likely to grow S aureus ( P < .001, P = .029, respectively). Conclusions: Although epidemiology of organisms associated with pediatric and adolescent bacteremia was similar to adults, risk factors were different than seen in that population. Further understanding of these risk factors may be helpful in developing preemptive infection control strategies in patients at risk.
