We sought to evaluate the success rate of a benzodiazepine-sparing analgosedation protocol (ASP) in mechanically ventilated children and determine the effect of compliance with ASP on in-hospital outcome measures. In this single center study from a quaternary pediatric intensive care unit, our objective was to evaluate the ASP protocol, which included opiate and dexmedetomidine infusions and was used as first-line sedation for all intubated patients. In this study we included 424 patients. Sixty-nine percent (n = 293) were successfully sedated with the ASP. Thirty-one percent (n = 131) deviated from the ASP and received benzodiazepine infusions. Children sedated with the ASP had decrease in opiate withdrawal (OR 0.16, 0.08–0.32), decreased duration of mechanical ventilation (adjusted mean duration 1.81 vs. 3.39 days, p = 0.018), and decreased PICU length of stay (adjusted mean 3.15 vs. 4.7 days, p = 0.011), when compared to the cohort of children who received continuous benzodiazepine infusions. Using ASP, we report that 69% of mechanically ventilated children were successfully managed with no requirement for continuous benzodiazepine infusions. The 69% who were successfully managed with ASP included infants, severely ill patients, and children with chromosomal disorders and developmental disabilities. Use of ASP was associated with decreased need for methadone use, decreased duration of mechanical ventilation, and decreased ICU and hospital length of stay.

ACE inhibitors (ACEis) and angiotensin receptor blockers (ARBs) are standard-of-care treatments for hypertension and diabetes, common comorbidities among hospitalized patients with coronavirus disease 2019 (COVID-19). Their use in the setting of COVID-19 has been heavily debated due to potential interactions with ACE2, an enzyme that links the pro-inflammatory and anti-inflammatory arms of the renin angiotensin system, but also the entryway by which severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) invades cells. ACE2 expression is altered by age, hypertension, diabetes, and the virus itself. This study integrated available information about the renin angiotensin aldosterone system (RAAS) and effects of SARS-CoV-2 and its comorbidities on ACE2 into a mechanistic mathematical model and aimed to quantitatively predict effects of ACEi/ARBs on the RAAS pro-inflammatory/ anti-inflammatory balance. RAAS blockade prior to SARS-CoV-2 infection is predicted to increase the mas-AT1 receptor occupancy ratio up to 20-fold, indicating that in patients already taking an ACEi/ARB before infection, the anti-inflammatory arm is already elevated while the pro-inflammatory arm is suppressed. Predicted proinflammatory shifts in the mas-AT1 ratio due to ACE2 downregulation by SARS-CoV-2 were small relative to antiinflammatory shifts induced by ACEi/ARB. Predicted effects of changes in ACE2 expression with comorbidities of diabetes, hypertension, or aging on mas-AT1 occupancy ratio were also relatively small. Last, predicted changes in the angiotensin (Ang(1-7)) production rate with ACEi/ARB therapy, comorbidities, or infection were all small relative to exogenous Ang(1-7) infusion rates shown experimentally to protect against acute lung injury, suggesting that any changes in the ACE2-Ang(1-7)-mas arm may not be large enough to play a major role in COVID-19 pathophysiology. Hypertension and diabetes are common comorbidities among hospitalized patients with coronavirus disease 2019 (COVID-19). 1 ACE inhibitors (ACEis) and angiotensin receptor blockers (ARBs) are standard of care treatment for these comorbidities, because they reduce cardiovascular events, kidney injury, and other vascular complications of these diseases. 2,3 There has been a good deal of

Eight percent of ED CT and 10% of ED US examinations were ordered and completed before documented clinical assessment. Thirty-three percent had incomplete clinical assessment performed prior to image interpretation. Further investigation is needed to determine impact on interpretation accuracy.

Objectives of this study were to (1) describe barriers to using clinical practice guideline (CPG) admission order sets in a pediatric hospital and (2) determine if integrating CPG order bundles into a general admission order set increases adoption of CPG-recommended orders compared to standalone CPG order sets. We identified CPG-eligible encounters and surveyed admitting physicians to understand reasons for not using the associated CPG order set. We then integrated CPG order bundles into a general admission order set and evaluated effectiveness through summative usability testing in a simulated environment. The most common reasons for the nonuse of CPG order sets were lack of awareness or forgetting about the CPG order set. In usability testing, CPG order bundle use increased from 27.8% to 66.6% while antibiotic ordering errors decreased from 62.9% to 18.5% with the new design. Integrating CPG-related order bundles into a general admission order set improves CPG order set use in simulation by addressing the most common barriers to CPG adoption.

Background: Physicians are exposed to workplace factors that may result in acute or chronic stress resulting in burnout. This may impact the productivity and result in suboptimal patient care practices. Methods:We surveyed pediatric cardiology attending physicians at our institution to assess their perception of burnout and work-life balance using the Maslach Burnout Inventory and the Areas of Work-Life Survey. Results: Forty-five out of the 50 pediatric cardiology attendings responded to the survey. They were divided into 4 groups: Interventional/Electrophysiology [n = 3], Cardiac Intensive Care/Inpatient [n = 8], Non-Invasive Imaging [n = 6], and Outpatient [n = 28]. The Maslach Burnout Inventory demonstrated group-specific scores in the areas of emotional exhaustion, depersonalization, and personal accomplishment that were all significantly better than the general population. However, group-specific Areas of Work-Life Survey results demonstrated concerning findings with respect to the perception of work-life balance.Conclusions: Although the Maslach Burnout Inventory did not demonstrate significant burnout among the attending physicians, the Areas of Work-Life Survey results demonstrated reduced work engagement, which can impact patient care and lead to burnout in the future. Based on these results, we plan to implement strategies to help increase work engagement and improve overall organizational effectiveness.

Introduction Atrial flutter (AFL) and atrial fibrillation (AF) are common in pediatric patients with congenital heart disease and structurally normal hearts as well. Chemical cardioversion is attractive for patients with AFL/AF for a short period of time because of the ability to avoid sedation. We review a single center's experience with Ibutilide in pediatric patients in an effort to report on its safety and efficacy. Methods We performed a retrospective chart review of pediatric patients (0‐21 years) who underwent chemical cardioversion for AFL/AF with Ibutilide (January 2011‐February 2019). Patients on another antiarrhythmic medication or attempted chemical cardioversion with another drug were excluded. Results There were 21 patients who met inclusion criteria. Thirteen of the 21 (62%) patients were successfully cardioverted with Ibutilide (10 out of 13 had AF and four out of 13 required a second dose). There were no significant differences in baseline characteristics between those who were successfully cardioverted compared to those who were not. Administration of magnesium prior to administration did not appear to have an effect on the success rate. There was a significant increase in rate corrected QT interval (QTc) post Ibutilide administration, which returned to baseline prior to discharge. One patient had symptomatic bradycardia needing intravenous fluids and another had torsades requiring electrical cardioversion during Ibutilide administration. Conclusions The success rate of chemical cardioversion with Ibutilide was similar in our experience as compared to studies in the adult population and the other lone pediatric study. Although adverse events were uncommon, Ibutilide administration warrants close monitoring and fully defining its efficacy warrants further pediatric experience.

Objective Autoimmune disorders result from the interplay of genetic and environmental factors. Many autoimmune disorders are associated with specific seasons of birth implicating a role for environmental determinants in their etiopathology. We investigated if there is an association between the season of birth and development of Juvenile idiopathic arthritis (JIA). Methods Birth data from 10,913 children with JIA enrolled at 62 Childhood Arthritis and Rheumatology Research Alliance Registry sites was compared with 109,066,226 US births from the same period using a Chi-square goodness-of-fit test. Season of birth of the JIA cohort was compared to the US population estimate using a two-sided one-sample test for a binomial proportion and corrected for multiple comparisons. Secondary analysis was performed for JIA categories, age of onset, and months of birth. Results A greater proportion of children with JIA were born in Winter (January to March) compared to the US population (25.72% vs 24.08%; pc < 0.0001). This observation was also true after stratifying for age of onset (≤ or > 6 years). When analyzed by the month of birth, a greater proportion of children with JIA were born in January compared to the US population (9.44% vs 8.13%; pc < 0.0001). Conclusion Relative to the general population, children with JIA are more often born in Winter, and specifically the month of January. These observations support the hypothesis that seasonal variations in exposures during the gestational and/or early postnatal periods may contribute to development of JIA.
