Infection surveillance in pediatric hematopoietic stem cell transplantation recipients

ObjectiveTo describe the profile of reported healthcare-associated infections (HAIs) in pediatric patients submitted to hematopoietic stem cell transplantation (HSCT) at a reference center. MethodsRetrospective cohort of pediatric patients who were submitted to HSCT from 2008 to 2016. The criteria for HAI were based on those established by the National Healthcare Safety Network. Data were collected by active surveillance performed daily by professionals. This study was approved by the institutional research ethics committee. ResultsA total of 86 HSCTs were performed in 81 patients younger than 18years of age (median, 10years). Of these, 69 (85%) were males. Aplastic anemia and leukemia were the main diagnoses. A total of 140 HAIs were diagnosed with an incidence density of 28.2 infections/1000 patient-days. The most common HAI was laboratory-confirmed bloodstream infection (46), the majority of which was reported to be central venous catheter-associated (43). Gram-negative bacteria were the most prevalent microorganisms (58.5%). Almost all the infections occurred until 30days after transplantation, and 17 deaths were observed within 180days after the procedure. ConclusionActive surveillance of HAIs in HSCT children allowed the evaluation of the incidence and profile of HAIs, which is essential for the health care of these patients.
