BACKGROUND AND OBJECTIVES: The impact of the coronavirus disease 2019 (COVID-19) pandemic on pediatric emergency department (ED) visits is not well characterized. We aimed to describe epidemiology ED and resource use during pandemic. METHODS: conducted a cross-sectional study using Pediatric Health Information System for 27 US children’s hospitals COVID-19 period (March 15, 2020, August 31, 2020) 3-year comparator 15 2017–2019). visit rates, patient characteristics, use, charges were...

Objective Entrustment describes the balance of supervision and autonomy between resident preceptor to complete doctoring tasks like procedures. alignment facilitates safe, successful outcomes, promotes learning. Study objectives describe procedural entrustment senior pediatric residents their preceptors report impact a simulation-based formative assessment (SFA) on alignment. Methods This prospective observational study enrolled convenience sample in 2023. The SFA was videoed, consisted...

This retrospective cohort study across 77 pediatric practices in Massachusetts assessed the frequency of CXR utilization among children with pneumonia diagnosed primary care setting and determined whether was associated differences antibiotic treatment outcomes. Multivariable logistic regression used to evaluate association between performance future clinic revisit, performance, change, a composite failure outcome, adjusting for markers illness severity. Among 29 528 treated pneumonia, 2462...

OBJECTIVES: Unlike community-acquired pneumonia (CAP), there is a paucity of data characterizing the patient demographics and hospitalization characteristics children with aspiration pneumonia. We used large national database US children’s hospitals to assess associated compared these patients CAP. METHODS: identified hospitalized diagnosis or CAP at 47 included in Pediatric Health Information System between 2009 2014. evaluated whether differences exist (median age proportion complex...

The diagnosis of pneumonia in children is challenging, given the wide overlap many symptoms and physical examination findings with other common respiratory illnesses. We sought to derive validate novel Pneumonia Risk Score (PRS), a clinical tool utilizing signs available clinicians determine child's risk radiographic pneumonia.We prospectively enrolled 3 months 18 years whom chest radiograph (CXR) was obtained emergency department evaluate for pneumonia. Before CXR, we collected information...

To assess the characteristics of children hospitalized with complicated pneumonia at US children's hospitals and compare these those community-acquired (CAP).We identified (parapneumonic effusion, empyema, necrotizing pneumonia, or lung abscess) CAP across 34 between 2011 2019. We evaluated differences in patient characteristics, antibiotic selection, outcomes CAP. We, also, assessed seasonal variability frequency 2 conditions prevalence over 9-year study period.Compared (n = 75 702), 6402)...

Prescription errors are a significant cause of iatrogenic harm in the health care system. Pediatric emergency department (ED) patients particularly vulnerable to error. We sought decrease prescription an academic pediatric ED by 20% over 24-month period implementing identified national best practice guidelines.From 2017 2019, multidisciplinary, fellow-driven quality improvement (QI) project was conducted using Model for Improvement. Four key drivers were including simplifying electronic...

Pediatric requirements include procedural skills training such as peripheral intravenous (PIV) catheter placement and bag-mask ventilation (BMV). Clinical experiences may be limited temporally remote from scheduled teaching. Just-in-time (JIT) prior to utilization can promote skill development mitigate learning decay. Our objective was assess the impact of JIT on pediatric residents' performance, knowledge, confidence with PIV BMV.

Abstract Background The practice of emergency medicine has become increasingly complex. Constant advances in clinical practice, innovative technologies, patient safety and quality initiatives, local national policy changes continue to add the cognitive load on providers. New professional development approaches are needed help providers remain current despite busy disparate clinician schedules. Methods We used a Web‐based, spaced education platform, distribute questions faculty fellows within...

SUMMARY Background Deliberate practice facilitates skill mastery. We aimed to create a novel resident‐as‐teacher rotation, leveraging deliberate framework with repeated in real‐life teaching settings, feedback from dedicated faculty member coaches. Methods A rotation was designed for 35 Postgraduate Year‐2 ( PGY 2) paediatric residents. To facilitate practice, experiences were observed by coaches and different audiences. Participating residents received pre‐rotation, post‐rotation follow‐up...

Strong relationships between trainees and physician supervisors can positively influence how navigate workplace learning. How act learn in clinical workplaces characterized by rapidly developing dissolving supervisory pairings is less well understood. This study uses the emergency department (ED) to examine impact of transient on residents approach learning opportunities.

Chest radiograph (CXR) is routinely performed among children with suspected pneumonia, though it not clear how specific radiographic findings impact antibiotic treatment for pneumonia. We evaluated the of viral features on undergoing pneumonia evaluation in emergency department (ED).Children presenting to a pediatric ED who underwent CXR were prospectively enrolled. Prior performance, physicians indicated their level suspicion The report was reviewed assess presence (peribronchial cuffing,...

Community-acquired pneumonia (CAP) is often considered for children presenting to the emergency department (ED) with respiratory symptoms. It unclear how are diagnosed CAP following an ED visit illness. We performed a retrospective case-control study evaluate 7-day diagnosis among 3 months 18 years discharged from illness 2011 2021 and who receive care at 4 hospital-affiliated primary clinics. Logistic regression was assess predictors of diagnosis. Seventy-four (0.7%, 95% confidence interval...
