RESUMO
Background: Despite national pediatric postcardiac arrest care (PCAC) guidelines to improve neurological outcomes and survival, there are limited studies describing PCAC delivery in pediatric institutions. This study aimed to describe PCAC delivery in centers belonging to a resuscitation quality collaborative. Methods: An institutional review board-approved REDCap survey was distributed electronically to the lead resuscitation investigator at each institution in the international Pediatric Resuscitation Quality Improvement Collaborative. Data were summarized using descriptive statistics. A chi-square test was used to compare categorical data. Results: Twenty-four of 47 centers (51%) completed the survey. Most respondents (58%) belonged to large centers (>1,000 annual pediatric intensive care unit admissions). Sixty-seven percent of centers reported no specific process to initiate PCAC with the other third employing order sets, paper forms, or institutional guidelines. Common PCAC targets included temperature (96%), age-based blood pressure (88%), and glucose (75%). Most PCAC included electroencephalogram (75%), but neuroimaging was only included at 46% of centers. Duration of PCAC was either tailored to clinical improvement and neurological examination (54%) or time-based (45%). Only 25% of centers reported having a mechanism for evaluating PCAC adherence. Common barriers to effective PCAC implementation included lack of time and limited training opportunities. Conclusions: There is wide variation in PCAC delivery among surveyed pediatric institutions despite national guidelines to standardize and implement PCAC.
RESUMO
Point-of-care ultrasound (POCUS) is increasingly accepted in pediatric critical care medicine as a tool for guiding the evaluation and treatment of patients. POCUS is a complex skill that requires user competency to ensure accuracy, reliability, and patient safety. A robust competency-based medical education (CBME) program ensures user competency and mitigates patient safety concerns. A programmatic assessment model provides a longitudinal, holistic, and multimodal approach to teaching, assessing, and evaluating learners. The authors propose a fit-for-purpose and modifiable CBME model that is adaptable for different institutions' resources and needs for any intended competency level. This educational model drives and supports learning, ensures competency attainment, and creates a clear pathway for POCUS education while enhancing patient care and safety.

Importance: Families and clinicians have limited validated tools available to assist in estimating long-term outcomes early after pediatric cardiac arrest. Blood-based brain-specific biomarkers may be helpful tools to aid in outcome assessment. Objective: To analyze the association of blood-based brain injury biomarker concentrations with outcomes 1 year after pediatric cardiac arrest. Design, Setting, and Participants: The Personalizing Outcomes After Child Cardiac Arrest multicenter prospective cohort study was conducted in pediatric intensive care units at 14 academic referral centers in the US between May 16, 2017, and August 19, 2020, with the primary investigators blinded to 1-year outcomes. The study included 120 children aged 48 hours to 17 years who were resuscitated after cardiac arrest, had pre-cardiac arrest Pediatric Cerebral Performance Category scores of 1 to 3 points, and were admitted to an intensive care unit after cardiac arrest. Exposure: Cardiac arrest. Main Outcomes and Measures: The primary outcome was an unfavorable outcome (death or survival with a Vineland Adaptive Behavior Scales, third edition, score of <70 points) at 1 year after cardiac arrest. Glial fibrillary acidic protein (GFAP), ubiquitin carboxyl-terminal esterase L1 (UCH-L1), neurofilament light (NfL), and tau concentrations were measured in blood samples from days 1 to 3 after cardiac arrest. Multivariate logistic regression and area under the receiver operating characteristic curve (AUROC) analyses were performed to examine the association of each biomarker with outcomes on days 1 to 3. Results: Among 120 children with primary outcome data available, the median (IQR) age was 1.0 (0-8.5) year; 71 children (59.2%) were male. A total of 5 children (4.2%) were Asian, 19 (15.8%) were Black, 81 (67.5%) were White, and 15 (12.5%) were of unknown race; among 110 children with data on ethnicity, 11 (10.0%) were Hispanic, and 99 (90.0%) were non-Hispanic. Overall, 70 children (58.3%) had a favorable outcome, and 50 children (41.7%) had an unfavorable outcome, including 43 deaths. On days 1 to 3 after cardiac arrest, concentrations of all 4 measured biomarkers were higher in children with an unfavorable vs a favorable outcome at 1 year. After covariate adjustment, NfL concentrations on day 1 (adjusted odds ratio [aOR], 5.91; 95% CI, 1.82-19.19), day 2 (aOR, 11.88; 95% CI, 3.82-36.92), and day 3 (aOR, 10.22; 95% CI, 3.14-33.33); UCH-L1 concentrations on day 2 (aOR, 11.27; 95% CI, 3.00-42.36) and day 3 (aOR, 7.56; 95% CI, 2.11-27.09); GFAP concentrations on day 2 (aOR, 2.31; 95% CI, 1.19-4.48) and day 3 (aOR, 2.19; 95% CI, 1.19-4.03); and tau concentrations on day 1 (aOR, 2.44; 95% CI, 1.14-5.25), day 2 (aOR, 2.28; 95% CI, 1.31-3.97), and day 3 (aOR, 2.04; 95% CI, 1.16-3.57) were associated with an unfavorable outcome. The AUROC models were significantly higher with vs without the addition of NfL on day 2 (AUROC, 0.932 [95% CI, 0.877-0.987] vs 0.871 [95% CI, 0.793-0.949]; P = .02) and day 3 (AUROC, 0.921 [95% CI, 0.857-0.986] vs 0.870 [95% CI, 0.786-0.953]; P = .03). Conclusions and Relevance: In this cohort study, blood-based brain injury biomarkers, especially NfL, were associated with an unfavorable outcome at 1 year after pediatric cardiac arrest. Additional evaluation of the accuracy of the association between biomarkers and neurodevelopmental outcomes beyond 1 year is needed.

INTRODUCTION: Pediatric quality improvement (QI) collaboratives are multisite clinical networks that support cooperative learning. Our goal is to identify the contextual facilitators and barriers to implementing QI resuscitation interventions within a multicenter resuscitation collaborative. METHODS: A mixed-methods evaluation of the contextual facilitators and barriers to implementation of a resuscitation QI bundle. We administered a quantitative questionnaire, the Model for Understanding Success in Quality (MUSIQ), to the Pediatric Resuscitation Quality (pediRES-Q) Collaborative. Its primary goal is to optimize the care of children who experience in-hospital cardiac arrest through a resuscitation QI bundle. We also conducted semistructured phone interviews with site primary investigators adapted from the Consolidated Framework for Implementation Research qualitative interview guide. RESULTS: All 13 actively participating US sites completed the MUSIQ questionnaire. Total MUSIQ scores ranged from 86.0 to 140.5 (median of 118.7, interquartile range 103.6-124.5). Evaluation of the QI team subsection noted a mean score of 5.5 for low implementers and 6.1 for high implementers (P = 0.02). We conducted 8 interviews with the local QI team leadership. Contextual facilitators included a unified institutional approach to QI, a fail forward climate, leadership support, strong microculture, knowledge of other organizations, and prioritization of goals. Contextual barriers included low team tenure, no specific allocation of resources, lack of formalized QI training, and lack of support and buy-in by leaders and staff. CONCLUSIONS: Using mixed methods, we identified an association between the local QI team's strength and the successful implementation of the QI interventions.
RESUMO
OBJECTIVES: Code team structure and training for pediatric in-hospital cardiac arrest are variable. There are no data on the optimal structure of a resuscitation team. The objective of this study is to characterize the structure and training of pediatric code teams in sites participating in the Pediatric Resuscitation Quality Collaborative. METHODS: From May to July 2017, an anonymous voluntary survey was distributed to 18 sites in the international Pediatric Resuscitation Quality Collaborative. The survey content was developed by the study investigators and iteratively adapted by consensus. Descriptive statistics were calculated. RESULTS: All sites have a designated code team and hospital-wide code team activation system. Code team composition varies greatly across sites, with teams consisting of 3 to 17 members. Preassigned roles for code team members before the event occur at 78% of sites. A step stool and backboard are used during resuscitations in 89% of surveyed sites. Cardiopulmonary resuscitation (CPR) feedback is used by 72% of the sites. Of those sites that use CPR feedback, all use an audiovisual feedback device incorporated into the defibrillator and 54% use a CPR coach. Multidisciplinary and simulation-based code team training is conducted by 67% of institutions. CONCLUSIONS: Code team structure, equipment, and training vary widely in a survey of international children's hospitals. The variations in team composition, role assignments, equipment, and training described in this article will be used to facilitate future studies regarding the impact of structure and training of code teams on team performance and patient outcomes.

PURPOSE: We sought to understand current POCUS practices and comfort as well as assess opinions about POCUS across our medical system via a survey to guide program development. METHODS: This study was conducted as a 19 question RedCap survey with multiple parts. Respondents were queried for demographics as well as experience with, attitudes toward, and clinical use of POCUS in common critical care scenarios. RESULTS: The survey was completed by 343 individuals, a response rate of 30%. Most respondents "agreed" that POCUS is a needed skill and helped them provide safer care (78% and 86% agreement). Most faculty and trainees reported some POCUS training (62% and 88%) and at least weekly use. Trainees rated themselves more comfortable than faculty for most exam types. The majority of faculty rated their POCUS education as inadequate while trainees had mixed responses. CONCLUSIONS: POCUS is a frequently used tool, yet users are less confident in their skills than expected. POCUS applications are viewed as needed for future practice but there is a substantial need for improved education among faculty and trainees. Pooling resources and sharing educational initiatives across multiple specialties may help improve POCUS implementation.

INTRODUCTION: Clinical event debriefing functions to identify optimal and suboptimal performance to improve future performance. "Cold" debriefing (CD), or debriefing performed more than 1 day after an event, was reported to improve patient survival in a single institution. We sought to describe the frequency and content of CD across multiple pediatric centers. METHODS: Mixed-methods, a retrospective review of prospectively collected in-hospital cardiac arrest (IHCA) data, and a supplemental survey of 18 international institutions in the Pediatric Resuscitation Quality (pediRES-Q) collaborative. Data from 283 IHCA events reported between February 2016 and April 2018 were analyzed. We used a Plus/Delta framework to collect debriefing content and performed a qualitative analysis utilizing a modified Team Emergency Assessment Measurement Framework. Univariate and regression models were applied, accounting for clustering by site. RESULTS: CD occurred in 33% (93/283) of IHCA events. Median time to debriefing was 26 days [IQR 11, 41] with a median duration of 60 minutes [20, 60]. Attendance was variable across sites (profession, number per debriefing): physicians 12 [IQR 4, 20], nurses 1 [1, 6], respiratory therapists 0 [0, 1], and administrators 1 [0, 1]. "Plus" comments reported per event were most commonly clinical standards 47% (44/93), cooperation 29% (27/93), and communication 17% (16/93). "Delta" comments were in similar categories: clinical standards 44% (41/93), cooperation 26% (24/93), and communication 14% (13/93). CONCLUSIONS: CDs were performed after 33% of cardiac arrests in this multicenter pediatric IHCA collaborative. The majority of plus and delta comments could be categorized as clinical standards, cooperation and communication.
RESUMO
Central venous access is an essential aspect of critical care for pediatric patients. In the critically ill pediatric population, image-guided procedures performed at the bedside expedite care and may reduce risks and logistical challenges associated with patient transport to a remote procedure suite such as interventional radiology. We describe our institutional technique for ultrasound-guided tunneled femoral venous access in neonates and infants and provide technical pearls from our experience, with an intended audience including specialists performing point-of-care ultrasound-guided procedures as well as interventional radiologist making their services available in the intensive care unit.

Point-of-care ultrasound is currently widely used across the landscape of pediatric care. Ultrasound machines are now smaller, are easier to use, and have much improved image quality. They have become common in emergency departments, ICUs, inpatient wards, and outpatient clinics. Recent growth of supportive evidence makes a strong case for using point-of-care ultrasound for pediatric interventions such as vascular access (in particular, central-line placement), lumbar puncture, fluid drainage (paracentesis, thoracentesis, pericardiocentesis), suprapubic aspiration, and soft tissue incision and drainage. Our review of this evidence reveals that point-of-care ultrasound has become a powerful tool for improving procedural success and patient safety. Pediatric patients and clinicians performing procedures stand to benefit greatly from point-of-care ultrasound, because seeing is believing.

Vilazodone hydrochloride is the first member in a new class of antidepressants called indolealkylamines and was approved for use in the United States in 2011 for major depressive disorder. It has a combined mechanism of action of a selective serotonin reuptake inhibitor and a partial agonist of serotonin 5-HT1A receptors. It has not been approved for use in the pediatric population, and toxicity from exploratory vilazodone ingestion has been rarely described to date. We describe 2 children with laboratory-confirmed vilazodone ingestions that led to significant toxicity including refractory status epilepticus in 1 patient and likely transient seizure activity in the other. Both patients required multiple doses of benzodiazepines; in the more severe case, barbiturates were added to control seizure activity. These children returned to baseline and had no prolonged neurologic complications. Pediatric experience with vilazodone is limited; however, the literature demonstrates 3 additional case reports of children experiencing seizure after vilazodone ingestion. With the 2 new cases presented here, it seems prudent to educate prescribers and families of the potential dangers of ingestion of vilazodone tablets by young children.

Erythropoiesis is a robust process of cellular expansion and maturation occurring in murine bone marrow and spleen. We previously determined that sublethal irradiation, unlike bleeding or hemolysis, depletes almost all marrow and splenic erythroblasts but leaves peripheral erythrocytes intact. To better understand the erythroid stress response, we analyzed progenitor, precursor, and peripheral blood compartments of mice post-4 Gy total body irradiation. Erythroid recovery initiates with rapid expansion of late-stage erythroid progenitors-day 3 burst-forming units and colony-forming units, associated with markedly increased plasma erythropoietin (EPO). Although initial expansion of late-stage erythroid progenitors is dependent on EPO, this cellular compartment becomes sharply down-regulated despite elevated EPO levels. Loss of EPO-responsive progenitors is associated temporally with a wave of maturing erythroid precursors in marrow and with emergence of circulating erythroid progenitors and subsequent reestablishment of splenic erythropoiesis. These circulating progenitors selectively engraft and mature in irradiated spleen after short-term transplantation, supporting the concept that bone marrow erythroid progenitors migrate to spleen. We conclude that sublethal radiation is a unique model of endogenous stress erythropoiesis, with specific injury to the extravascular erythron, expansion and maturation of EPO-responsive late-stage progenitors exclusively in marrow, and subsequent reseeding of extramedullary sites.

OBJECTIVE: Clastogenic injury of the erythroid lineage results in anemia, reticulocytopenia, and transient appearance of micronucleated reticulocytes. However, the micronucleated reticulocyte dose-response in murine models is only linear to 2 Gy total body irradiation and paradoxically decreases at higher exposures, suggesting complex radiation effects on erythroid intermediates. To better understand this phenomenon, we investigated the kinetics and apoptotic response of the erythron to sublethal radiation injury. MATERIALS AND METHODS: We analyzed the response to 1 and 4 Gy total body irradiation of erythroid progenitors and precursors using colony assays and imaging flow cytometry, respectively. We also investigated cell cycling and apoptotic gene expression of the steady-state erythron. RESULTS: After 1 Gy total body irradiation, erythroid progenitors and precursors were partially depleted. In contrast, essentially all bone marrow erythroid progenitors and precursors were lost within 2 days after 4 Gy irradiation. Imaging flow cytometry analysis revealed preferential loss of phenotypic erythroid colony-forming units and proerythroblasts immediately after sublethal irradiation. Furthermore, these populations underwent radiation-induced apoptosis, without changes in steady-state cellular proliferation, at much higher frequencies than later-stage erythroid precursors. Primary erythroid precursor maturation is associated with marked Bcl-xL upregulation and Bax and Bid downregulation. CONCLUSIONS: Micronucleated reticulocyte loss after higher sublethal radiation exposures results from rapid depletion of erythroid progenitors and precursors. This injury reveals that erythroid colony-forming units and proerythroblasts constitute a particularly proapoptotic compartment within the erythron. We conclude that the functional transition of primary proerythroblasts to later-stage erythroid precursors is characterized by a shift from a proapoptotic to an antiapoptotic phenotype.
