Eliminating inappropriate antibiotic use in pediatric lower respiratory tract infections (LRTI) is the central focus of this research. LRTIs (pneumonia, bronchiolitis, and infection-related exacerbations of asthma) account for nearly one-third of all emergency department (ED) visits and 40% of all infection-related hospitalizations in US children. LRTIs also account for more antibiotic use in children's hospitals than any other condition, despite most LRTIs being viral in nature. Inappropriate antibiotics are associated with substantial adverse effects. Accordingly, national guidelines strongly discourage routine antibiotic use for bronchiolitis and acute asthma and argue for significantly reducing antibiotic exposure (initiation, spectrum, and duration) in pneumonia. To address the problem of inappropriate antibiotic use, hospital-based antimicrobial stewardship programs (ASPs) are now common nationwide, and these programs have demonstrated effectiveness in some hospital settings. Unfortunately, traditional ASP approaches do not translate well to the fast-paced and unpredictable ED environment, and hospital-based ASP resources are finite and not always immediately available. Clinical decision support (CDS) embedded within the electronic health record (EHR) is a strategy that could address the ED antibiotic stewardship gap. Informed by a deep understanding of the key facilitators and barriers to using CDS to support appropriate antibiotic use in ED and hospital settings, the investigators have developed two stewardship-focused CDS interventions for pediatric LRTI. The overarching goal of this research is to rigorously evaluate the implementation and effectiveness of these CDS tools, alone and in combination, against usual care only in a pragmatic randomized clinical trial at 3 U.S. children's hospitals.
This is a usual care-controlled superiority clinical trial platform designed to evaluate the effects of hospital-based CDS in the ED (CDS-ED) and after transitioning to the hospital setting (CDS-TR) on antibiotic prescribing and related clinical outcomes for child and adolescent LRTI encounters at 3 U.S. children's hospitals. The investigators hypothesize that both interventions will be superior to usual care and, among patients presenting in the ED and subsequently admitted to the hospital, the combined interventions (CDS-ED + CDS-TR) will be most effective overall. Randomization will occur sequentially in two stages corresponding to the ED CDS and Transitions CDS populations. The first stage of randomization will allocate qualifying ED encounters 1:1 to CDS-ED vs. usual care alone in the ED. The second stage of randomization will allocate participants requiring hospitalization (those discharged from the hospital are not eligible) 1:1 to CDS-TR vs. usual care at the time of admission. To minimize bias, the trial will be embedded within clinical care with minimal exclusions and disruption to usual care activities. Investigators will be blinded to study arm assignment, though blinding of treating clinicians is not possible due to the nature of the study. The trial will also evaluate process and implementation outcomes throughout the study period within the platform population. A formal interim analysis is not planned.

The ED-CDS intervention is designed as a discrete decision support aid to influence initial antibiotic decision-making in the ED. This intervention will feature a clinician-facing LRTI dashboard for end-users that assimilates relevant clinical data (e.g., vital signs, select diagnostic tests, links to reference information) and offers tailored suggestions for antibiotic initiation, related diagnostic testing, and in those receiving antibiotics, preferred options and alternatives for antibiotic choice, route, dose, and duration.
The CDS-Tr intervention is designed as a longitudinal decision support aid to influence initial and ongoing (i.e., continuation, discontinuation, escalation, or de-escalation) antibiotic decision-making in the hospital setting. This intervention will also feature the LRTI dashboard along with additional tailored suggestions and recommendations for antibiotic decision-making upon hospital admission, and for those receiving antibiotics, at the time of discharge. Additionally, CDS-Tr will be active at the time of any service transition (i.e., hospital to intensive care or vice versa) and at pre-specified time points (e.g., approximately 48 hours and 120 hours following ED triage for encounters remaining in the hospital).

RECRUITINGPrimary Effectiveness: 10-day Longitudinal Antimicrobial Spectrum Index
The Antibiotic Spectrum Index (ASI) is a numerical metric which quantifies the relative breadth of antimicrobial activity of a given antibiotic medication. Tracking the 10-day trajectory of ASI will capture changes in antibiotic use resulting from changes in antibiotic initiation, spectrum of antibiotic activity, and duration of antibiotic use.
Time frame: 10 days
Primary Safety: Proportion of Participants Experiencing Escalation in Treatment
Treatment escalation will capture the escalation to higher level of care and/or antibiotic treatment strategy
Time frame: 10 days
Effectiveness: Proportion of Participants Experiencing Reduction of ASI Score
De-escalation of antibiotic exposure intensity (1+ level decrease in daily antibiotic exposure intensity) for a duration of at least 72 hours during the first 10 days of treatment
Time frame: 10 days
Effectiveness: Total Treatment Duration
Days until cessation of antibiotic exposure (i.e., daily periods with an ASI score greater than 0) for the index encounter, inclusive of antibiotics received in the ED and hospital, as well as any additional days of antibiotics prescribed at discharge up to 42 days after enrollment.
Time frame: 42 days
Effectiveness: ASI per Exposure Day
The numerator is the cumulative ASI during the first 10 days of treatment (T0-T240) and the denominator is the number of days of antibiotic exposure (i.e., daily periods with an ASI score greater than 0) during this same period.
Time frame: 10 days
Safety: Need for Intensive Care
Use of intensive care at any point during index encounter
Time frame: 42 days
Safety: Need for Invasive Mechanical Ventilation or Shock Requiring Vasoactive Medications
Need for intubation and/or need for vasoactive medications to manage uncompensated shock at any point during the index encounter (excludes intubation or vasoactive medications used for or during planned procedures or surgical intervention)
Time frame: 42 days
Safety: 3- and 14-day ED Reutilization
Any ED revisit occurring within 72 and 336 hours of index discharge that does not result in hospitalization
Time frame: 14 days
Safety: 3- and 14-day Hospital Reutilization
Any re-hospitalization occurring within 72 and 336 hours of index discharge
Time frame: 14 days
Death within 14 days of index discharge
Death by any cause occurring: 1) during the index encounter; 2) within 14 days of the index discharge, or 3) reutilization occurring within 14 days of the index discharge and that results in death at any time during that encounter
Time frame: 14 days
