Pediatric-specific safety data are required during development of pharmaceutical agents. Retrospective studies can leverage real-world data to assess safety and effectiveness in children where prospective, controlled studies are not feasible. A retrospective cohort study combined data from Pediatric Health Information Systems (PHIS) and medical records to evaluate the safety and effectiveness of piperacillin/tazobactam (P/T) in pediatric patients with hospital-acquired pneumonia (HAP).

Preventing unnecessarily long durations of antibiotic therapy is a key opportunity to reduce antibiotic overuse in children 2 years of age and older with acute otitis media (AOM). Pragmatic interventions to reduce durations of therapy that can be effectively scaled and sustained are urgently needed. This study aims to fill this gap by evaluating the effectiveness and implementation outcomes of two low-cost interventions of differing intensities to increase guideline-concordant antibiotic durations in children with AOM.

Background: Concerns that athletes may be at a higher risk for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission has led to reduced participation in sports during the COVID-19 pandemic. We aimed to assess COVID-19 incidence and transmission during the spring 2021 high school and college water polo seasons across the United States.

Methods: This prospective observational study enrolled 1825 water polo athletes from 54 high schools and 36 colleges.

Background: Antibiotic-resistant infections have become a public health crisis that is driven by the inappropriate use of antibiotics. In the USA, antibiotic stewardship programs (ASP) have been established and are required by regulatory agencies to help combat the problem of antibiotic resistance. Post-operative antibiotic use in surgical cases deemed low-risk for infection is an area with significant overuse of antibiotics in children.

Optimizing pediatric antimicrobial stewardship is challenging. In this retrospective study, we evaluated 515 original e-mails to 482 members of the Sharing Antimicrobial Reports for Pediatric Stewardship (SHARPS) Collaborative electronic mailing list (idlistserv@kids.wustl.

In this point-prevalence study of 32 US children's hospitals, we determined that 1.7% of hospitalized children received at least 1 antimicrobial agent for a non-infection-related reason; macrolides were used most commonly. Antimicrobial stewardship efforts to understand and affect use for these reasons is an unmet need; additional research considering the individual and societal effects of these antimicrobial-prescribing practices should be undertaken.

Background: Studies estimate that 30%-50% of antibiotics prescribed for hospitalized patients are inappropriate, but pediatric data are limited. Characterization of inappropriate prescribing practices for children is needed to guide pediatric antimicrobial stewardship.

Methods: Cross-sectional analysis of antibiotic prescribing at 32 children's hospitals in the United States.

Background: Indoleamine-2,3-dioxygenase (IDO) catalyzes the first step of tryptophan (Trp) catabolism, yielding kynurenine (Kyn) metabolites. The kynurenine-to-tryptophan (K/T) ratio is used as a surrogate for biological IDO enzyme activity. IDO expression is increased during Escherichia coli urinary tract infection (UTI).

In response to the growing epidemic of antibiotic-resistant bacterial infections, antimicrobial stewardship programs (ASP) have been rapidly implemented in the United States (US). This study examines the prevalence of the Centers for Disease Control and Prevention's (CDC) seven core elements of a successful ASP within a large subset of US Children's Hospitals. In 2016, a survey was conducted of 52 pediatric hospitals assessing the presence of the seven core elements: leadership commitment, accountability, drug expertise, action, tracking, reporting, and education.

Background: Silent cerebral infarct (SCI) is the most common cause of serious neurological disease in sickle cell anemia (SCA), affecting approximately 22% of children. The goal of this trial is to determine whether blood transfusion therapy will reduce further neurological morbidity in children with SCI, and if so, the magnitude of this benefit.

Procedure: The Silent Cerebral Infarct Transfusion (SIT) Trial includes 29 clinical sites and 3 subsites, a Clinical Coordinating Center, and a Statistical and Data Coordinating Center, to test the following hypothesis: prophylactic blood transfusion therapy in children with SCI will result in at least an 86% reduction in the rate of subsequent overt strokes or new or progressive cerebral infarcts as defined by magnetic resonance imaging (MRI) of the brain.

Drug metabolism in children may differ from adults and adverse events may occur that are not predictable from the adult experience. Clinical trials of safety and efficacy are needed both for new treatments and those that may already be in use but have not been tested in infants and children. The role and responsibilities of different participants in a trial are discussed, including the steering committee, the clinical and statistical co-ordinating centers, and the data and safety monitoring board.

Objective: To test the hypothesis that children with sickle cell disease (SCD) who have an initial stroke temporally unrelated to another medical event are at higher risk for recurrent stroke than are children who had strokes temporally related to medical events.

Methods: A retrospective cohort study of children with SCD and stroke who received regularly scheduled blood transfusions for a minimum of 5 years was conducted. Medical records were examined for the documentation of antecedent or concurrent medical events (hypertension, acute chest syndrome, aplastic crisis, fever associated with infection, exchange transfusion) associated with physician contact within 14 days before the initial stroke.
