Individualized Antibiotic Plans as a Quality Improvement Initiative to Reduce Carbapenem Use for Hematopoietic Cell Transplant Patients at a Freestanding Pediatric Hospital.

BACKGROUND: Providers must balance effective empiric therapy against toxicity risks and collateral damage when selecting antibiotic therapy for patients receiving hematopoietic cell transplant (HCT). Antimicrobial stewardship interventions during HCT are often challenging due to concern for undertreating potential infections. METHODS: In an effort to decrease unnecessary carbapenem exposure for patients undergoing HCT at our pediatric center, we implemented individualized antibiotic plans (IAPs) to provide recommendations for preengraftment neutropenia prophylaxis, empiric treatment of febrile neutropenia, and empiric treatment for hemodynamic instability. We compared monthly antibiotic days of therapy (DOT) adjusted per 1000 patient-days for carbapenems, antipseudomonal cephalosporins, and all antibiotics during two 3-year periods immediately before and after the implementation of IAPs to measure the impact of IAP on prescribing behavior. Bloodstream infection (BSIs) and Clostridioides difficile (CD) positivity test rates were also compared between cohorts. Last, providers were surveyed to assess their experience of using IAPs in antibiotic decision making. RESULTS: Overall antibiotic use decreased after the implementation of IAPs (monthly reduction of 19.6 DOT/1000 patient-days; P = .004), with carbapenems showing a continuing decline after IAP implementation. BSI and CD positivity rates were unchanged. More than 90% of providers found IAPs to be either extremely or very valuable for their practice. CONCLUSIONS: Implementation of IAPs in this high-risk HCT population led to reduction in overall antibiotic use without increase in rate of BSI or CD test positivity. The program was well received by providers.

Pediatric Antimicrobial Stewardship Programs Reduce Antibiotic Use at Combined Adult-Pediatric Hospitals.

Implementation of dedicated pediatric antimicrobial stewardship programs (ASPs) at 2 combined adult-pediatric hospitals with existing ASPs was associated with sustained decreases in pediatric antibiotic use out of proportion to declines seen in adult inpatient units. ASPs in combined hospitals may not detect excessive pediatric antibiotic use without incorporating pediatric expertise.

Increased Pediatric Respiratory Syncytial Virus Case Counts Following the Emergence of SARS-CoV-2 Can Be Attributed to Changes in Testing.

BACKGROUND: Respiratory syncytial virus (RSV) circulation dropped markedly early in the COVID-19 pandemic, followed by a resurgence with heightened case counts. The "immunity debt" hypothesis proposes that the RSV-naїve pediatric population increased during the period of low transmission. However, the evidence supporting this hypothesis is limited, and the role of changing testing practices in the perceived surge has not been comprehensively evaluated. METHODS: We conducted a multicenter, retrospective analysis of 342 530 RSV encounters and 980 546 RSV diagnostic tests occurring at 32 US pediatric hospitals in 2013-2023. We used interrupted time series analysis to estimate pandemic-associated changes in RSV patient and test volume and to quantify changes in the proportions of patients requiring hospitalization, intensive care, or mechanical ventilation. We quantified the fraction of the shifts in case counts and in the age of diagnosed patients attributable to changes in testing. RESULTS: RSV patient volume increased 2.4-fold (95% confidence interval [CI]: 1.7, 3.5) in 2021-2023 relative to the pre-pandemic phase and was accompanied by an 18.9-fold increase (95% CI: 15.0, 23.9) in RSV test volume. Shifts in patient volume and in patient age were largely attributable to increased testing. The proportions of patients with RSV that required hospitalization, intensive care, or mechanical ventilation declined significantly across all patient age groups. CONCLUSIONS: A surge in RSV testing, rather than in viral circulation, likely underlies the increased case counts observed in 2021-2023. These findings warrant a critical assessment of the immunity debt hypothesis and highlight the importance of considering the testing denominator when surveillance strategies are dynamic.

Project Baby Bear: Rapid precision care incorporating rWGS in 5 California children's hospitals demonstrates improved clinical outcomes and reduced costs of care.

Genetic disorders are a leading contributor to mortality in neonatal and pediatric intensive care units (ICUs). Rapid whole-genome sequencing (rWGS)-based rapid precision medicine (RPM) is an intervention that has demonstrated improved clinical outcomes and reduced costs of care. However, the feasibility of broad clinical deployment has not been established. The objective of this study was to implement RPM based on rWGS and evaluate the clinical and economic impact of this implementation as a first line diagnostic test in the California Medicaid (Medi-Cal) program. Project Baby Bear was a payor funded, prospective, real-world quality improvement project in the regional ICUs of five tertiary care children's hospitals. Participation was limited to acutely ill Medi-Cal beneficiaries who were admitted November 2018 to May 2020, were <1 year old and within one week of hospitalization, or had just developed an abnormal response to therapy. The whole cohort received RPM. There were two prespecified primary outcomes-changes in medical care reported by physicians and changes in the cost of care. The majority of infants were from underserved populations. Of 184 infants enrolled, 74 (40%) received a diagnosis by rWGS that explained their admission in a median time of 3 days. In 58 (32%) affected individuals, rWGS led to changes in medical care. Testing and precision medicine cost $1.7 million and led to $2.2-2.9 million cost savings. rWGS-based RPM had clinical utility and reduced net health care expenditures for infants in regional ICUs. rWGS should be considered early in ICU admission when the underlying etiology is unclear.

Genetic Testing in Patients with Autoimmune Lymphoproliferative Syndrome: Experience of 802 Patients at Cincinnati Children's Hospital Medical Center.

Autoimmune lymphoproliferative syndrome (ALPS) is a rare genetic disorder featuring chronic lymphadenopathy, splenomegaly, cytopenias, and increased lymphoma risk. Differentiating ALPS from immunodeficiencies with overlapping symptoms is challenging. This study evaluated the performance and the diagnostic yield of a 15-gene NGS panel for ALPS at Cincinnati Children's Hospital Medical Center. Samples from 802 patients submitted for ALPS NGS panel were studied between May 2014 and January 2023. A total of 62 patients (7.7%) had a definite diagnosis: 52/62 cases (84%) showed 37 unique pathogenic/likely pathogenic germline FAS variants supporting ALPS diagnosis (6.5%, 52/802). The ALPS diagnostic yield increased to 30% in patients who additionally fulfilled abnormal ALPS immunology findings criteria. 17/37 (46%) diagnostic FAS variants were novel variants reported for the first time in ALPS. 10/802 cases (1.2%) showed diagnostic findings in five genes (ADA2, CTLA4, KRAS, MAGT1, NRAS) which are related to autoimmune lymphoproliferative immunodeficiency (ALPID). Family studies enabled the reclassification of variants of unknown significance (VUS) and also the identification of at-risk family members of FAS-positive patients, which helped in the follow-up diagnosis and treatment. Alongside family studies, complete clinical phenotypes and abnormal ALPS immunology and Fas-mediated apoptosis results helped clarify uncertain genetic findings. This study describes the largest cohort of genetic testing for suspected ALPS in North America and highlights the effectiveness of the ALPS NGS panel in distinguishing ALPS from non-ALPS immunodeficiencies. More comprehensive assessment from exome or genome sequencing could be considered for undefined ALPS-U patients or non-ALPS immunodeficiencies after weighing cost, completeness, and timeliness of different genetic testing options.

Age-specific Dose Catalog for Diagnostic Fluoroscopy and Fluoroscopically Guided Interventional Procedures from a Pediatric Hospital.

Background Fluoroscopy is an imaging modality associated with a wide range of dose levels, characterized using a variety of dose metrics, including effective dose. However, for clinical procedures, effective dose is a seldom-used and unregulated metric in the United States, and thus, it is not extensively studied in radiology despite potentially large clinical implications for patients, especially children and infants. Purpose To formulate and report a dose catalog across all diagnostic and interventional radiology (IR) fluoroscopy examination or procedure types at a specialized tertiary care pediatric hospital. Materials and Methods In this retrospective study, dose metrics taken from radiation dose structured reports of fluoroscopy between October 2014 and March 2023 were analyzed. The reports included fluoroscopy across 18 diagnostic examination types and 24 IR procedure types. The National Cancer Institute dosimetry system for Radiography and Fluoroscopy Monte Carlo software was used to estimate age-specific effective dose from dose-area product (DAP). The DAP-to-effective dose conversion factors were estimated per IR procedure type and diagnostic fluoroscopy examination type based on age. Results A total of 11 536 individual diagnostic fluoroscopy examinations (18 types) and 8017 individual IR procedures (24 types) were analyzed. Median effective dose values per diagnostic fluoroscopy examination type ranged from 0.0010 to 0.44 mSv (mean, 0.0808 mSv ± 0.0998 [SD]). Calculated DAP-to-effective dose conversion factors ranged from 0.04 to 2.48 mSv/Gy · cm2 (mean, 0.758 mSv/Gy · cm2 ± 0.614) across all diagnostic fluoroscopy examination types. Median effective dose values per IR procedure type ranged from 0.0007 to 3.90 mSv (mean, 0.6757 mSv ± 0.8989). Calculated DAP-to-effective dose conversion factors ranged from 0.001 to 0.87 mSv/Gy · cm2 (mean, 0.210 mSv/Gy · cm2 ± 0.235) across all IR procedure types. Conclusion A pediatric fluoroscopy dose catalog was created, including age-specific effective dose, using a repeatable robust method based on accurate clinical data. © RSNA, 2024 Supplemental material is available for this article.

Cerebral Oximetry During Pediatric In-Hospital Cardiac Arrest: A Multicenter Study of Survival and Neurologic Outcome.

OBJECTIVES: To determine if near-infrared spectroscopy measuring cerebral regional oxygen saturation (crS o2 ) during cardiopulmonary resuscitation is associated with return of spontaneous circulation (ROSC) and survival to hospital discharge (SHD) in children. DESIGN: Multicenter, observational study. SETTING: Three hospitals in the pediatric Resuscitation Quality (pediRES-Q) collaborative from 2015 to 2022. PATIENTS: Children younger than 18 years, gestational age 37 weeks old or older with in-hospital cardiac arrest (IHCA) receiving cardiopulmonary resuscitation greater than or equal to 1 minute and intra-arrest crS o2 monitoring. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Primary outcome was ROSC greater than or equal to 20 minutes without extracorporeal membrane oxygenation. Secondary outcomes included SHD and favorable neurologic outcome (FNO) (Pediatric Cerebral Performance Category 1-2 or no change from prearrest). Among 3212 IHCA events (index and nonindex), 123 met inclusion criteria in 93 patients. Median age was 0.3 years (0.1-1.4 yr) and 31% (38/123) of the cardiopulmonary resuscitation events occurred in patients with cyanotic heart disease. Median cardiopulmonary resuscitation duration was 8 minutes (3-28 min) and ROSC was achieved in 65% (80/123). For index events, SHD was achieved in 59% (54/91) and FNO in 41% (37/91). We determined the association of median intra-arrest crS o2 and percent of crS o2 values above a priori thresholds during the: 1) entire cardiopulmonary resuscitation event, 2) first 5 minutes, and 3) last 5 minutes with ROSC, SHD, and FNO. Higher crS o2 for the entire cardiopulmonary resuscitation event, first 5 minutes, and last 5 minutes were associated with higher likelihood of ROSC, SHD, and FNO. In multivariable analysis of the infant group (age < 1 yr), higher crS o2 was associated with ROSC (odds ratio [OR], 1.06; 95% CI, 1.03-1.10), SHD (OR, 1.04; 95% CI, 1.01-1.07), and FNO (OR, 1.05; 95% CI, 1.02-1.08) after adjusting for presence of cyanotic heart disease. CONCLUSIONS: Higher crS o2 during pediatric IHCA was associated with increased rate of ROSC, SHD, and FNO. Intra-arrest crS o2 may have a role as a real-time, noninvasive predictor of ROSC.

What's the CATCH? A Participatory Learning Model for Case Review Rounds to Support a Culture of Safety and Quality Improvement in Pediatric Hospital Medicine.

OBJECTIVE: To evaluate the effectiveness of a new model, Case Analysis and Translation to Care in Hospital (CATCH), for the review of pediatric inpatient cases when an adverse event or "close call" had occurred. STUDY DESIGN: The curricular intervention consisted of an introductory podcast/workshop, mentorship of presenters, and monthly CATCH rounds over 16 months. The study was conducted with 22 pediatricians at a single tertiary care center. Intervention assessment occurred using participant surveys at multiple intervals: pre/post the intervention, presenter experience (post), physicians involved and mentors experience (post), and after each CATCH session. Paired t-tests and thematic analysis were used to analyze data. Time required to support the CATCH process was used to assess feasibility. RESULTS: Our overall experience and data revealed a strong preference for the CATCH model, high levels of engagement and satisfaction with CATCH sessions, and positive presenter as well as physicians-involved and mentor experiences. Participants reported that the CATCH model is feasible, engages physicians, promotes a safe learning environment, facilitates awareness of tools for case analysis, and provides opportunities to create "CATCH of the Day" recommendations to support translation of learning to clinical practice. CONCLUSIONS: The CATCH model has significant potential to strengthen clinical case rounds in pediatric hospital medicine. Future research is needed to assess the effectiveness of the model at additional sites and across medical specialities.

Analysis of the prevalence and clinical features of respiratory syncytial virus infection in a pediatric hospital in Zhejiang Province from 2019 to 2023.

The aim of this study was to investigate the epidemiological characteristics of respiratory syncytial virus (RSV) infections in children in Zhejiang from 2019 to 2023. Data from pediatric patients who visited the Children's Hospital of Zhejiang University School of Medicine for RSV infection between 2019 and 2023 were analyzed. Nasopharyngeal swabs were collected for RSV antigen detection, and relevant patient information was collected. Factors such as age were analyzed. A total of 673 094 specimens were included from 2019 to 2023, with a rate of positive specimens of 4.74% (31 929/673 094). The highest rate of positive specimens of 10.82%, was recorded in 2021, while the remaining years had a rate of approximately 3%-5%. In terms of seasonal prevalence characteristics, the rate of positive specimens in 2019, 2020, and 2022 peaked in the winter months at approximately 8% and decreased in the summer months, where the rate of positive specimens remained at approximately 0.5%. In contrast, summer is the peak period for RSV incidence in 2021 and 2023, with the rate of positive specimens being as high as 9%-12%. Based on the prevalence characteristics of gender and age, this study found that the detection rate of positive specimens was higher in boys than in girls in 2019-2023. In 2019-2022, among the different age groups, the highest rate of positive specimens was found in children aged 0 to <6 months, and it decreased with age. In 2023, the rate of positive specimens was above 8% in the 0 to <6 months, 6 to <12 months, and 1-2 years age groups, with the highest rate of positive specimens in the 1-2 years age group, and a gradual decrease in the rate of positive specimens with age for children over 3 years of age. Between 2019 and 2023, the epidemiological pattern of RSV changed. A summer peak was observed in 2021 and 2023.

Introduction of transcatheter edge-to-edge repair in patients with congenital heart disease at a children's hospital.

BACKGROUND: Atrioventricular valve regurgitation (AVVR) is a devastating complication in children and young adults with congenital heart disease (CHD), particularly in patients with single ventricle physiology. Transcatheter edge-to-edge repair (TEER) is a rapidly expanding, minimally invasive option for the treatment of AVVR in adults that avoids the morbidity and mortality associated with open heart surgery. However, application of TEER in in CHD and in children is quite novel. We describe the development of a peri-procedural protocol including image-derived pre-intervention simulation, with successful application to four patients. AIMS: To describe the initial experience using the MitraClip system for TEER of dysfunctional systemic atrioventricular valves in patients with congential heart disease within a pediatric hospital. METHODS: A standardized screening and planning process was developed using cardiac magnetic resonance imaging, three dimensional echocardiography and both virtual and physical simulation. Procedures were performed using the MitraClip G4 system and patients were clinically followed post-intervention. RESULTS: A series of four CHD patients with at least severe AVVR were screened for suitability for TEER with the MitraClip system: three patients had single ventricle physiology and Fontan palliation, and one had repair of a common atrioventricular canal defect. Each patient had at least severe systemic AVVR and was considered at prohibitively high risk for surgical repair. Each patient underwent a standardized preprocedural screening protocol and image-derived modeling followed by the TEER procedure with successful clip placement at the intended location in all cases. CONCLUSIONS: The early results of our protocolized efforts to introduce TEER repair of severe AV valve regurgitation with MitraClip into the CHD population within our institution are encouraging. Further investigations of the use of TEER in this challenging population are warranted.

Pediatric invasive device utility and harm: a multi-site point prevalence survey.

BACKGROUND AND AIMS: Invasive devices are widely used in healthcare settings; however, pediatric patients are especially vulnerable to invasive device-associated harm. This study aimed to explore invasive device utility, prevalence, harm, and clinical practice across three Australian pediatric tertiary hospitals. METHODS: In 2022-2023, a multi-center, observational, rolling-point-prevalence survey was conducted. Fifty-per-cent of inpatients were systemically sampled by random allocation. Patients with devices were then followed for up to 3-days for device-related complications/failures and management/removal characteristics. RESULTS: Of the 285 patients audited, 78.2% had an invasive device (n = 412 devices), with a median of 1 device-per-patient (interquartile range 1-2), with a maximum of 13 devices-per-patient. Over half of devices were vascular access devices (n = 223; 54.1%), followed by gastrointestinal devices (n = 112; 27.2%). The point-prevalence of all device complications on Day 0 was 10.7% (44/412 devices) and period-prevalence throughout the audit period was 27.7% (114/412 devices). The period-prevalence of device failure was 13.4% (55/412 devices). CONCLUSIONS: The study highlighted a high prevalence of invasive devices among hospitalized patients. One-in-ten devices failed during the audit period. These findings underscore the need for vigilant monitoring and improved strategies to minimize complications and enhance the safety of invasive devices in pediatric hospital settings. IMPACT: A high prevalence of invasive devices among hospitalized patients was reported. Of the 285 patients audited, almost 80% had an invasive device (total 412 devices), with a median of 1 device-per-patient and a maximum of 13 devices-per-patient. The most common devices used in pediatric healthcare are vascular access devices (n = 223; 54.1%), however, 16% (n = 36) of these devices failed, and one-third had complications. The point prevalence of all device complications at day 0 was 10.7% (44 out of 412 devices), with a period prevalence of 27.7% (114 out of 412 devices) throughout the audit period.

Developing a process to measure actual harm from medication errors in paediatric inpatients: From design to implementation.

AIMS: The potential harm associated with medication errors is widely reported, but data on actual harm are limited. When actual harm has been measured, assessment processes are often poorly described, limiting their ability to be reproduced by other studies. Our aim was to design and implement a new process to assess actual harm resulting from medication errors in paediatric inpatient care. METHODS: Prescribing errors were identified through retrospective medical record reviews (n = 26 369 orders) and medication administration errors through direct observation (n = 5137 administrations) in a tertiary paediatric hospital. All errors were assigned potential harm severity ratings on a 5-point scale. Multidisciplinary panels reviewed case studies for patients assigned the highest three potential severity ratings and determined the following: actual harm occurrence and severity level, plausibility of a link between the error(s) and identified harm(s) and a confidence rating if no harm had occurred. RESULTS: Multidisciplinary harm panels (n = 28) reviewed 566 case studies (173 prescribing related and 393 administration related) and found evidence of actual harm in 89 (prescribing = 22, administration = 67). Eight cases of serious harm cases were found (prescribing = 1, administration = 7) and no cases of severe harm. The panels were very confident in 65% of cases (n = 302) where no harm was found. Potential and actual harm ratings varied. CONCLUSIONS: This harm assessment process provides a systematic method for determining actual harm from medication errors. The multidisciplinary nature of the panels was critical in evaluating specific clinical, therapeutic and contextual considerations including care delivery pathways, therapeutic dose ranges and drug-drug and drug-disease interactions.

Clinical Characteristics of Avoidable Patient Transfers for Suspected Pediatric Appendicitis.

INTRODUCTION: Pediatric surgical care is becoming increasingly regionalized, often resulting in limited access. Interfacility transfers pose a significant financial and emotional burden to when they are potentially avoidable. Of transferred patients, we sought to identify clinical factors associated with avoidable transfers in pediatric patients with suspected appendicitis. METHODS: We performed a single-center retrospective study at an academic tertiary referral children's hospital in an urban setting. We included children who underwent interfacility transfer to our center with a transfer diagnosis of appendicitis from July 1, 2021 to June 30, 2023. Encounters were designated as either an appropriate transfer (underwent appendectomy) or an avoidable transfer (did not undergo appendectomy). Encounters treated nonoperatively for complicated appendicitis were excluded. Bivariate analysis was performed using Mann-Whitney test and chi-square tests. RESULTS: A total of 444 patients were included: 71.2% were classified as appropriate transfers and 28.8% as avoidable transfers. Patients with avoidable transfer were younger compared to those in the appropriate transfer cohort (median age 9 y, interquartile range: 7-13 versus 11 y, interquartile range: 8-14; P < 0.001). Avoidable transfers less frequently presented with the typical symptoms of fever, migratory abdominal pain, anorexia, and nausea/emesis (P = 0.005). Avoidable transfers also reported shorter symptom duration (P = 0.040) with lower median white blood cell count (P < 0.001), neutrophil percentage (P < 0.001), and C-reactive protein levels (P < 0.003). Avoidable transfers more frequently underwent repeat imaging upon arrival (42.9% versus 12.7%, P < 0.001). CONCLUSIONS: These findings highlight the importance of clinical history in children with suspected appendicitis. Younger patients without typical symptoms of appendicitis, those with a shorter duration of symptoms, and lower serum inflammatory markers may benefit from close observation without transfer.

Heart Transplantation for Adults With Congenital Heart Disease Can Be Performed at Adult or Pediatric Hospitals With Comparable Outcomes.

INTRODUCTION: The goal of this study was to evaluate the relationship between hospital-related factors and hospital type on outcomes of heart transplantation for patients with adult congenital heart disease (ACHD). METHODS: Patients with ACHD who underwent heart transplant between 2010 and 2021 were identified using the United Network for Organ Sharing data registry. The primary outcome was post-transplant mortality. Kaplan-Meier unadjusted survival curves were compared using the log-rank test. Multivariable Cox proportional hazard models were used for risk-adjustment in evaluating the independent effect of hospital type on post-transplant mortality. RESULTS: Of 70 centers, 54 (77.1%) adult centers performed 415 (87.0%) heart transplants and 16 (22.9%) pediatric centers performed 62 (13.0%) heart transplants. Patients transplanted at pediatric centers were younger, had lower creatinine levels, and had lower body mass index. The unadjusted 1-y and 5-y survival was comparable in pediatric versus adult centers, respectively: 93.4% versus 86.6% (log-rank P = 0.16) and 87.4% versus 73.9% (log-rank P = 0.06). These findings persisted after risk-adjustment. One-year mortality hazard ratio for pediatric hospitals: 0.64 (0.22-1.89, P = 0.416) and 5-y mortality hazard ratio for pediatric hospitals: 0.53 (0.21-1.33, P = 0.175). Rates of acute rejection, postoperative stroke, and new-onset postoperative dialysis were also comparable. CONCLUSIONS: Heart transplantation for patients with ACHD can be performed safely in adult centers. The majority of heart transplant for ACHD in the United States are performed at adult hospitals. However, further research is needed to delineate the impact of individual surgeon characteristics and hospital-related factors on outcomes.

Commercial markups on pediatric oncology drugs at 340B pediatric hospitals.

Eligible pediatric hospitals can purchase clinician-administered drugs at discounted rates through the 340B Drug Pricing Program and charge payers prices exceeding drug acquisition costs, but the magnitude of these markups is not known. In a study of newly approved oncology drugs at pediatric 340B hospitals, median negotiated prices ranged from 102% (interquartile range [IQR]: 91%-156%) of average sales price (ASP) at Phoenix Children's Hospital to 630% (IQR: 526%-630%) at Driscoll Children's Hospital. Pediatric hospitals participating in the federal 340B Drug Pricing Program can extract steep payments on new drugs from commercial insurers, though with wide variation between and within hospitals.

High burden of acute respiratory tract infections leading to hospitalization at German pediatric hospitals: fall/winter 2022-2023.

PURPOSE: Given reduced immunity levels for seasonally occurring respiratory infections and the experience of an unusually early, severe wave of RSV infections during 2021, a preexisting clinician-led reporting system (CLRS) was updated to prospectively monitor the anticipated high burden of respiratory infections (ARI) in German pediatric hospitals during fall/winter 2022-2023. METHODS: From September 13, 2022 through March 31, 2023, children hospitalized with ARI as a primary diagnosis were monitored via a national CLRS established by the German Society for Pediatric Infectious Diseases (DGPI). Once a week, the CLRS collected overall number of new hospital admissions, ARI-related admissions according to pathogen (SARS-CoV-2, RSV, influenza, and other), plus number of patients admitted to ICU with ARI as a primary diagnosis. RESULTS: With a high participation among children's hospitals across Germany (22.8%), 76 centers submitted 1,053 survey reports. ARI-related hospital admissions showed a steep rise starting in late September 2022 and reached their highpoint in early December 2022 (50.1% of all admissions). In parallel, the average number of newly admitted patients (aNA) with RSV (3.6) peaked, as did those with influenza (2.1) one week later. The average highpoint of ARI patients on ICU (aICU) (2.9) was reached shortly thereafter. Again, RSV (1.6) und influenza (1.2) were predominant pathogens. CONCLUSION: In fall/winter 2022-2023, German hospitals reported a sharp increase in patients with ARIs. While RSV and influenza represented the greatest proportion of ARI, SARS-CoV-2 played a less significant role. Systematic, dynamic collection of ARI data is critical for assessing real burdens on the health care system.

Implementation of a Program for Appendicitis MRI in a Pediatric Hospital.

MRI is increasingly used as an alternate to CT for the evaluation of suspected appendicitis in pediatric patients presenting to the emergency department (ED) with abdominal pain, when further imaging is needed after an initial ultrasound examination. The available literature shows a similar diagnostic performance of MRI and CT in this setting. At the authors' institution, to evaluate for appendicitis in children in the ED, MRI is performed using a rapid three-sequence free-breathing protocol without IV contrast media. Implementation of an MRI program for appendicitis in children involves multiple steps, including determination of imaging resource availability, collaboration with other services to develop imaging pathways, widespread educational efforts, and regular quality review. Such programs can face numerous practice-specific challenges, such as those involving scanner capacity, costs, and buy-in of impacted groups. Nonetheless, through careful consideration of these factors, MRI can be used to positively impact the care of children presenting to the ED with suspected appendicitis. This Clinical Perspective aims to provide guidance on the development of a program for appendicitis MRI in children, drawing on one institution's experience while highlighting the advantages of MRI and practical strategies for overcoming potential barriers.

Pediatric Sepsis in General Emergency Departments: Association Between Pediatric Sepsis Case Volume, Care Quality, and Outcome.

STUDY OBJECTIVE: To assess whether a general emergency department's (ED) annual pediatric sepsis volume increases the odds of delivering care concordant with Surviving Sepsis pediatric guidelines. METHODS: A retrospective cohort study of children <18 years with sepsis presenting to 29 general EDs. Emergency department and hospital data were abstracted from the medical records of 2 large health care systems, including all hospitals to which children were transferred. Guideline-concordant care was defined as intravenous antibiotics within 3 hours, intravenous fluid bolus within 3 hours, and lactate measured. The association between annual ED pediatric sepsis encounters and the probability of receiving guideline-concordant care was assessed. RESULTS: We included 1,527 ED encounters between January 1, 2015, and September 30, 2021. Three hundred and one (19%) occurred in 25 EDs with <10 pediatric sepsis encounters annually, 466 (31%) in 3 EDs with 11 to 100 pediatric sepsis encounters annually, and 760 (50%) in an ED with more than 100 pediatric sepsis encounters annually. Care was concordant in 627 (41.1%) encounters. In multivariable analysis, annual pediatric sepsis volume was minimally associated with the probability of guideline-concordant care (odds ratio 1.002 [95% confidence interval 1.001 to 1.00]). Care concordance increased from 23.1% in 2015 to 52.8% in 2021. CONCLUSION: Guideline-concordant sepsis care was delivered in 41% of pediatric sepsis cases in general EDs, and annual ED pediatric sepsis encounters had minimal association with the odds of concordant care. Care concordance improved over time. This study suggests that factors other than pediatric sepsis volume are important in driving care quality and identifying drivers of improvement is important for children first treated in general EDs.

Evaluation of Insurance Type as a Proxy for Socioeconomic Status in the Pediatric Emergency Department: A Pilot Study.

STUDY OBJECTIVE: To determine whether insurance status can function as a sufficient proxy for socioeconomic status in emergency medicine research by examining the concordance between insurance status and direct socioeconomic status measures in a sample of pediatric patients. METHODS: We conducted a cross-sectional pilot study of patients aged 5 to 17 years in the emergency department of a quaternary care children's hospital. Socioeconomic status was measured using the highest level of the caregiver's education (low: less than bachelor's degree; high: bachelor's or greater) and previous year household income (low: <$75,000; high: ≥$75,000). We calculated the misclassification rate of insurance status (low: public; high: private) using education and income as reference standards. Results were expressed as percentages with 95% confidence intervals. RESULTS: In total, 300 patients were enrolled (median age 11 years, 44% female). Insurance status misclassified 23% (95% CI 18% to 28%) and 14% (95% CI 10% to 19%) of patients when using caregiver education and income, respectively, as reference standards. CONCLUSIONS: Insurance status misclassified socioeconomic status in up to 23% of pediatric patients, as measured by caregivers' education and income. Emergency medicine studies of pediatric patients using insurance as a covariate to adjust for socioeconomic status may need to consider this misclassification and the resulting potential for bias. These findings require confirmation in larger, more diverse samples, including adult patients.

The 4 S's of Disaster Management Framework: A Case Study of the 2022 Pediatric Tripledemic Response in a Community Hospital.

Most children in the United States present to community hospitals for emergency department (ED) care. Those who are acutely ill and require critical care are stabilized and transferred to a tertiary pediatric hospital with intensive care capabilities. During the fall of 2022 "tripledemic," with a marked increase in viral burden, there was a nationwide surge in pediatric ED patient volume. This caused ED crowding and decreased availability of pediatric hospital intensive care beds across the United States. As a result, there was an inability to transfer patients who were critically ill out, and the need for prolonged management increased at the community hospital level. We describe the experience of a Massachusetts community ED during this surge, including the large influx in pediatric patients, the increase in those requiring critical care, and the total number of critical care hours as compared with the same time period (September to December) in 2021. To combat these challenges, the pediatric ED leadership applied a disaster management framework based on the 4 S's of space, staff, stuff, and structure. We worked collaboratively with general emergency medicine leadership, nursing, respiratory therapy, pharmacy, local clinicians, our regional health care coalition, and emergency medical services (EMS) to create and implement the pediatric surge strategy. Here, we present the disaster framework strategy, the interventions employed, and the barriers and facilitators for implementation in our community hospital setting, which could be applied to other community hospital facing similar challenges.
