Abstract

Introduction: Bacteremia is a frequent complication in children with cancer, which is associated with greater severity, prolonged hospitalization and mortality. Prolonged hospitalization conditions greater morbidity and risk of acquisition of intranosocomial infections. Aim: To describe risk factors for prolonged hospital length of stay in children with leukemia and bacteremia. Methods: Cohort study. Episodes of bacteremia in patients with leukemia at Garrahan Hospital from 1/1/2015 to 31/12/2016 were reviewed. We compared data from patients with a LOS of 14 days or more with those admitted for less than 14 days. Bivariate and logistic regression analysis was performed. We used Stata 13 statistical package. Results: n = 121. Median age 59 months.81 patients (67%) had a diagnosis of acute lymphoblastic leukemia, followed by acute myeloid leukemia in 40 (33%). 96 patients (79%) had a central venous catheter (CVC), 94 patients (78%) were neutropenic. Blood cultures were positive for Enterobacteriaceae in 55 cases (45%), coagulase-negative staphylococci in 28 cases (23%), Group viridans Streptococcus in 19 (16%), Pseudomonas aeruginosa in 8 (7%). (9%). By the multivariate analysis, three factors remained significantly associated with length of stay of more than 14 days: CVC associated bacteremia (OR 21,73; CI95% 1.2- 43.2; p 0.04), severe neutropenia (OR 1.75; CI95% 1.82-1.28; p 0.03) and coinfection (OR 27.4; CI95% 2.8-260.8; p 0.004). Conclusion: CVC associated bacteremia, severe neutropenia and viral coinfection were associated with hospital LOS of more than 14 days.
