  Assessing Early Use and Complications of Gastrostomy Blended Feeds.

  James Fraser, Kristen L. Sayers, Amy L. Pierce, Beth A. Orrick, Wendy Jo Svetanoff, Tolulope A. Oyetunji MD MPH, and Shawn D. St Peter

  Providers are hesitant to recommend using blended tube feeds (BF) after gastrostomy tube (GT) placement due to increased risk of bacterial contamination, nutrition inadequacy, tube blockages, and lack of data addressing clinical outcomes. Caregivers often feel that BF are more natural, better tolerated, and more cost-effective. We studied early use of BF, potential complications, and satisfaction among caregivers.

  Descriptive Study of the Safety Behaviors and Attitudes of Portable Pool Owners

  Kristyn Jeffries, Kathy W. Monroe, Alicia Webb, Kristin L. Chancellor, Justina C. Goldman, and David C. Schwebel

  Background Drowning is the leading cause of injury death for children 1-4 years old and the second leading cause for children 5-9 years old. Most prior epidemiology work has focused on submersions in below-ground swimming pools and natural bodies of water. Portable pools pose a new and emerging risk for drowning due to their affordability, convenience, and easy assembly. Successful drowning prevention consumer products, such as 4-sided fencing, may prove more difficult to implement with portable pools, and currently are not marketed for such use. Furthermore, parental perceptions and knowledge of drowning risks associated with portable pools has not yet been well studied.

  Methods We performed a prospective study of caregivers to children aged 9 months to 6 years in an urban pediatric emergency department during summer 2021. Enrolled caregivers were given a QR code that directed them to complete a self-administered questionnaire on their mobile device. Survey questions assessed the caregivers’ access to portable pools and their safety behaviors and attitudes related to portable pools. Frequencies of portable pool ownership, caregivers’ safety practices while using them, and caregivers’ behavioral perceptions were calculated.

  Results Of the 85 caregivers enrolled in the study, 54% reported either owning or having access to a portable pool. Of the subset who owned portable pools, a majority (n=23/28) bought their portable pool in 2021, but only 28% (n=8/28) used any safety products with their pool and only 10% had previously enrolled their child in formal swim lessons. The primary reasons portable pool owners did not use safety products included perceived lack of necessity of such products for portable pools and confidence in close supervision while their child is swimming. While all caregivers (n=85/85) responded they would always watch their child in the shallow end of a below-ground pool, 14% (n=12/85) of caregivers responded they would only watch their child intermittently while in a portable pool. Over 48% (n=41/85) of caregivers thought they would hear their child if he/she was drowning in a portable pool.

  Conclusions Parents may underestimate the risk associated with portable pools, which could contribute to young children’s risk of drowning in these pools. These results provide insights that could be used in the development of drowning prevention messaging and the development of prevention strategies specifically targeting portable pool users.

  Pharmacogenetic Testing In Patients with Autism Spectrum Disorder Evaluated in a Pediatric Precision Medicine Clinic

  Rachel Goodson, Cy Nadler, Jennifer A. Wagner, Sarah Soden, Sarah Nyp, and Tracy L. Sandritter

  Pharmacogenetic Testing In Patients with Autism Spectrum Disorder Evaluated in a Pediatric Precision Medicine Clinic Purpose The purpose of this study is to investigate the demographic and presentation profiles of children with autism spectrum disorder (ASD) who present for evaluation in a pediatric precision medicine clinic. Methods: This retrospective, observational cohort study utilized data extracted from a pediatric precision medicine clinic database between 2010 and 2021 with recorded ICD9/10 codes of Autism Spectrum Disorder, Autistic Disorder, Pervasive Developmental Disorder, or Asperger’s Syndrome. Extracted variables included demographic data, presenting medication regimens and concerns to be addressed by precision medicine. Results: A sample of 202 patients was identified (see Table 1). Patients referred for precision medicine services were primarily due to poor medication response (64.8%) and/or adverse drug reactions (48.5%). Referrals were made by subspecialists (78.2%), primary care providers (16.3%), and via self-referral (4.95%). At presentation to the clinic, patients were already prescribed between 1-10 medications (Mean = 6.15, Median 5; see Figure 1). Medications with indication commonly used for sleep, gastrointestinal disorders, and psychiatric/behavioral disorders were among the most common medications taken at the time of evaluation (see Figure 2). At time of presentation to the clinic, males and females did not differ in terms of age (t= 1.22, p = 0.22) or number of medications taken (t = 0.994, p = 0.323). Age was also not significantly associated with number of medications (F = 0.277, p = 0.527). Conclusions: Youth with ASD presenting for precision medicine consultation experienced notable degrees of polypharmacy, with no clear differences associated with sex or age. Trends may emerge with the addition of a typically developing control group, and the robustness of associations must be evaluated in samples drawn from a wider variety of practice settings. While these findings are primarily descriptive, the data fill a critical gap regarding the characteristics of youth with ASD referred for precision medicine. Few dedicated precision medicine clinics exist, yet this service is increasingly recommended for youth with autism due to higher rates of adverse drug reactions and clinical nonresponse. More research is needed to establish how precision medicine fits within existing evidence-based guidelines and can most effectively serve this population.

  Kayla B. Briggs, Obiyo O. Osuchukwu, Chris E. Roberts, James Fraser, Wendy Jo Svetanoff, Tolulope A. Oyetunji, and Hanna Alemayehu

  Racial Disparities in Testicular Torsion Introduction: Testicular torsion (TT) is a surgical emergency requiring prompt intervention to preserve testicular function. Race and insurance status are thought to be associated with higher rates of gonadal loss; however, reports in the literature are conflicting. We sought to determine the effect of race on the treatment and outcomes of testicular torsion. Methods: Following IRB approval, a retrospective review was conducted of patients <18 years of age who presented to 2 institutions>(hereby referred to as H1 and H2) with acute scrotal pain between December 2017 and September 2019. Demographic data, clinical history, imaging results, diagnosis, and surgical outcomes were recorded. Social vulnerability index (SVI), as determined by zip code, was obtained from the Centers for Disease Control and dichotomized using the 75th percentile. Higher SVI denotes increased social vulnerability. Primary outcome was diagnosis of TT. Secondary outcomes included orchiectomy rates. A p-value <0.05 was considered significant. Results: A total of 515 patients (H1 85%, H2 15%) were included in the final analysis. There were no difference in median age, BMI, TT diagnosis and orchiectomy rate between the two institutions. H2 treated more black patients (43% vs. 14%, p=<0.01) and patients with public insurance (57% vs. 41%, p=0.03) compared to H1. In multivariate analysis, older age was associated with TT (median age TT 14.12 years [12.13,15.69]) vs. no TT 9.86 years [5,13.05], OR 1.35, 95% CI 1.18-1.55, p=<0.01). Black patients were ~4 times more likely (OR 4.05, 95% CI 2.13-7.69, p=<0.01) than white patients to be diagnosed with TT when controlled for dichotomized SVI, insurance, and age. In the same model, Hispanic patients were ~2 times more likely (OR 2.20, 95% CI 1.10-4.40, p=0.03) to be diagnosed with TT when compared to white patients. Despite more black and Hispanic patients having dichotomized SVI >75th percentile than white patients (70% and 82%, respectively vs. 16%, p=<0.01), dichotomized SVI was not found to be associated with higher rates of TT or orchiectomy, respectively. Conclusion: At the two centers, more black and Hispanic children had SVI >75th percentile, however, when controlling for this in multivariate analysis, they were significant more likely to be diagnosed with testicular torsion. Conversely, there was no difference in orchiectomy rate between races.

  Severe diastolic dysfunction following prolonged extracorporeal membrane oxygenation in a pediatric burn patient.

  Cara Holton, Johanna I. Orrick, Igor Areinamo, and Jenna Miller

  A previously healthy 3-year-old female was admitted following a 22% TBSA scald burn. She was initially hemodynamically stable on room air. However, one week into hospitalization she developed ARDS with catecholamine-refractory shock requiring VA-ECMO. She was enterovirus positive, grew MRSA in respiratory cultures and was treated with prolonged antibiotics. The patient spent 26 days on VA-ECMO followed by 61 days on VV- ECMO after failing decannulation due to refractory hypoxia. She developed anuric renal failure requiring CRRT during her second ECMO course. Following VV-ECMO decannulation, she required mechanical ventilation with high settings and had severe recurrent pulmonary hemorrhage requiring FFP, platelets and inhaled TXA. She had coronary dilation on CT imaging but was COVID-19 antibody negative. Serial echocardiograms demonstrated moderate LV dilation with normal systolic function. It was difficult to assess her diastolic function by echo, but with clinical concern for dysfunction she was started on milrinone. She underwent cardiac catheterization due to pulmonary bleeding and concerns for pulmonary hypertension. She had severely elevated biventricular filling pressures (RVEDp of 38 and LVEDp of 55) indicative of diastolic dysfunction. She had a high baseline cardiac index and normal PVR on milrinone and sildenafil. She also had significant AP collateral burden requiring coiling. Following this procedure her pulmonary hemorrhage resolved but her pulmonary mechanics did not improve. She continued to have multi-system organ failure with cardiac dysfunction, respiratory and renal failure. Her family did not wish to pursue organ transplantation and chose to redirect her care. This case is remarkable for several reasons. While large burns are known to produce an inflammatory response with cardiac dysfunction (1, 2), typically the degree of inflammation is proportional to the size of the burn and occurs early (3). This patient had a smaller TBSA burn that did not require surgery, yet she developed profound respiratory failure and shock requiring ECMO. During her hospitalization and 87 days on ECMO, the patient developed severe diastolic heart failure, AP collateral burden and coronary ectasia. This case demonstrates the utility of a diagnostic cardiac catheterization to evaluate for hemodynamic abnormalities after prolonged ECMO support, especially when echocardiogram is unrevealing. It is impossible to say whether these findings were a result of her prolonged ECMO runs, her burn physiologic state, or potentially a synergistic combination of the two. Additionally, while “long run” ECMO is becoming more common, little is known about the long-term cardiovascular effects of ECMO physiology. We report this case to encourage others to share cardiovascular complications after ECMO runs greater than 21 days.

  Short and Long Term Outcomes of Using Cryoablation for Post-operative Pain Control in Patients After Pectus Excavatum Repair

  James Fraser, Kayla B. Briggs, Wendy Jo Svetanoff, David Juang, Pablo Aguayo, Jason D. Fraser, Charles L. Snyder, Tolulope A. Oyetunji, and Shawn D. St. Peter MD

  Background: Previous prospective trials have demonstrated that intercostal cryoablation reduces length of stay and postoperative opioid consumption compared with thoracic epidural and patient controlled analgesia (PCA) modalities. We report the findings of a 3-year prospective, observational study to elucidate long-term pain control, symptoms, and complications with attention to postoperative short and long-term pain control associated with the cryoablation technique.
  
  Methods: Following IRB approval, we prospectively collected data on patients who underwent bar placement for pectus excavatum with thoracoscopic intercostal cryoablation by six surgeons at our institution from 2017 to 2021. Patients and their parents completed surveys regarding pain scores, narcotic and non-narcotic pain medication usage, and limitations to activity beginning on the day of surgery for up to 10 days, with a supplementary survey on the day of discharge to evaluate pain and associated symptoms. Surveys were administered at two-week and three-month follow-up appointments addressing pain control, symptoms, and limitations to activity. Retrospective review of chart data was performed to identify the number of emergency department visits, phone calls to the outpatient surgery office, and requirement for additional pain medication.
  
  Results: 110 patients were included in the analysis; 90% were male with a median age of 15.8 years [14.6, 16.7]. The median length of stay was 25.6 hours [22.3, 31.7]. Forty-eight patients (44%) completed the discharge survey; sharp pain and pressure on the first night of surgery were the most described pain characteristics, with sharp pain being the worst symptom reported most frequently in the middle of the chest. (Table 1) On postoperative follow-up, 55% of patients reported tolerable residual pain at two weeks and 41% at three months, with a median pain score of 3 at each follow-up interval and 25% of survey respondents requiring intermittent non-narcotic pain medication at three months. There were 18 (16%) ED visits by two-week follow-up, resulting in 3 readmissions for inadequate pain control: two on postoperative day two and one on postoperative day five. By three-month follow-up, there were 65 calls to the surgery clinic, most commonly for persistent pain and frequent popping sensation with movement, and no additional patients required readmission for pain control within this longer interval. (Table 2)
  
  Conclusion: Although cryoablation is an excellent pain control modality to attenuate the acute insult of bar placement, these data suggest that patients underreport functional symptoms and experience more frequent discomfort and alteration of activities of daily living than perceived by providers. Prospective validation is necessary to examine the nature of specific symptoms, duration, and impact on the patient’s quality of life.

  Improving Skin and Soft Tissue Antibiotic Duration Concordance with National Guidelines in Pediatric Urgent Care Clinics

  Megan Hamner, Amanda Nedved, Holly Austin, Donna Wyly, Alaina N. Burns, Diana King, Brian Lee, and Rana El Feghaly

  Introduction: Skin and soft tissue infections (SSTIs) are the second most common diagnosis leading to pediatric antibiotic prescriptions in the outpatient setting after respiratory diagnoses. Children with SSTIs often receive >7 days of antibiotics, although current guidelines recommend 5-7 days for most diagnoses. At CMH urgent care clinics (UCCs), only 58% patients received the recommended 5-7 days of antibiotics. We aimed to increase the percentage of patients receiving 5-7 days of oral antibiotics for SSTIs from 58% to 75% by December 31st, 2021. Methods: We formed a multidisciplinary team in April 2020. A provider survey assessed factors influencing prescribing habits. We completed cause-and-effect analyses and developed a driver diagram (Figure 1). Interventions were chosen based on the potential for highest impact and lowest effort. Our first Plan-Do-Study-Act (PDSA) cycle provided an update on current guidelines for UCC providers. The second PDSA cycle updated prescription sentences in the electronic health record (EHR) and organized them from shortest to longest duration. The third PDSA cycle provided a project update via email to UCC providers. Our outcome measure is the percentage of patients receiving 5-7 days of antibiotics for SSTIs. Process measure is the number of updated prescriptions used. Balancing measure is the number of patients returning for SSTI within 14 days of their visit. Results are displayed using a run chart. Results: After initiation of the project in April 2020, the percentage of patients receiving 5-7 days of antibiotics increased to 68% (Figure 2). This percentage increased to our goal of 75% after the 1st PDSA cycle (October-December 2020), 80% following the second PDSA cycle in February 2021, and 90% following the third PDSA cycle in April 2021. There was no change in balancing measure numbers. Conclusion: Prior to our project, only 58% of children seen in CMH UCCs for SSTIs received the recommended antibiotic duration. By addressing the primary drivers uncovered through QI methodology, we surpassed our goal of 75%. Additional PDSA cycles are planned along with expansion to other departments. This work will allow us to expand antibiotic stewardship efforts to other infectious diagnoses as well.

  Reconsidering Perioperative Antibiotic Use in Elective Laparoscopic Cholecystectomy

  Kayla B. Briggs, James Fraser, Wendy Jo Svetanoff, Charles L. Snyder, Pablo Aguayo, David Juang, Rebecca M. Rentea, Jason D. Fraser, Shawn D. St. Peter MD, and Tolulope A. Oyetunji

  Introduction: Prophylactic preoperative antibiotics (PPA) are questionable in cases with a low rate of surgical site infection (SSI). We report institutional PPA usage and SSI rates after elective laparoscopic cholecystectomy in a children’s hospital. Methods: Children <18 years old who underwent outpatient laparoscopic cholecystectomy between 7>/2010 and 8/2020 were included. SSI was defined as clinical signs of infection, requiring antibiotics, within 30 days of surgery. Results: 502 patients met inclusion criteria; 50% were pre-operatively diagnosed with symptomatic cholelithiasis, 47% biliary dyskinesia, 2% hyperkinetic gallbladder, and 1% gallbladder polyp(s). The majority were female (78%) and Caucasian (80%). 60% (n=301) of patients received PPA while 40% (n=201) did not; 1.3% (n=4) of those who received PPA developed SSI compared to 5.5% (n=11) of those who did not (p=0.01). Though PPA use was associated with an 84% reduction in risk of SSI on multivariate analysis (p=0.01), all SSIs were superficial. One child required readmission for intravenous antibiotics while the remainder were treated with outpatient antibiotics. Gender, age, BMI, ethnicity, and preoperative diagnosis did not influence the likelihood of receiving PPA (Table 1). Conclusion: Given the relatively low morbidity of the superficial SSI, conservative use of PPA should be carefully considered in outpatient laparoscopic cholecystectomy to avoid contributing to antibiotic-related complications.

  Challenges in Echocardiographic Diagnosis of Corrected Malposition of Great Arteries: The Segmental Approach coming Handy

  Amulya Buddhavarapu, Anmol Goyal, Sanket Shah, Nitin Madan, Hayley S. Hancock, and Maria Kiaffas

  Clinical Presentation

  Two cases of {S,D,L} anatomically corrected malposition of great arteries (ACMGA) are presented with differences in conal anatomy. Case 1: A fetal echocardiogram (echo) performed at 28 weeks gestation due to multiple anomalies revealed atrial situs solitus, D-loop ventricles, a large conoventricular septal defect (VSD) and an overriding, anterior and leftward aorta. The diagnosis of double outlet right ventricle (DORV) vs ACGMA was entertained. Postnatal echo revealed {S,D,L} segmental anatomy with ventriculoarterial concordance consistent with ACGMA and a muscular VSD. Case 2: A 3-week-old boy presented to clinic for a murmur evaluation with no associated cardiac symptoms. Transthoracic echocardiogram revealed {S,D,L} ACGMA and a small membranous VSD.

  Imaging Findings

  Echocardiographic subcostal, parasternal and suprasternal sweeps help diagnose ACGMA by delineating ventriculoarterial alignment, ventricular and outflow relations and conal anatomy. Case 1, a rare ACMGA type, posed the most diagnostic challenges. A more anterior rotation of the left ventricle, horizontal orientation of the ventricular septum due to absence of a sub-pulmonary conus, in combination with an elongated subaortic conus led to the misconception of an overriding aorta and DORV prenatally. Pulmonary to tricuspid valve fibrous continuity was present. The unusual position of the aortic valve resulted in an elongated curvature of a left aortic arch, coursing from anterior and right towards the left of the trachea. Case 2, the most typical type of {S,D,L} ACGM, had the usual anatomic characteristics of bilateral sub-arterial conus and parallel outflow tracts. In both cases cardiac magnetic resonance imaging was performed for evaluation of the Qp/Qs caused by the VSD and confirmed the diagnosis of ACGMA.

  Roles of Imaging in Patient Care

  Accurate prenatal diagnosis of ACMGA is essential for appropriate counseling and postnatal management. Postnatally, standard echocardiographic views and multimodality imaging will elucidate ventriculoarterial connections, conal anatomy, and severity of associated anomalies.

  Discussion

  ACMGA is a rare congenital heart disease occurring from failure of involution and rightward rotation of the subaortic conus resulting to a parallel spatial relationship of the great arteries while maintaining ventriculo-arterial concordance. Subtypes include {S,D,L} (most common, usually with bilateral conus) and {I,L,D} with normal, and {S,L,D} and {I,D,L} with transposition physiology. Identifying the segmental anatomy and relations will result in accurate diagnosis of this rare entity.

  Correlation between strain and weight status in infants with a univentricular hear

  Amulya Buddhavarapu, Mathew Warren, Lori Erickson, Christopher Mathis, Whitney Haas, and Daniel Forsha

  Background

  Infants with univentricular physiology are at risk of poor weight gain and reduced ventricular function, both of which have been independently associated with worse outcomes. Since nutritional status has been correlated to ventricular function in other populations, we evaluated the relationship between nutritional status and ventricular function including speckle-tracking strain during this period.

  Methods

  Thirty term infants (median age 55 days, 13 females) with univentricular physiology prior to stage II palliation were included with data obtained at the time of their initial hospital discharge. Ventricular function was quantified using 2D global longitudinal strain (GLS) and strain rate, analyzed from an apical “4-chamber” view (TomtecCPA 2.31). Ventricular myocardium was tracked along the dominant walls producing systolic ejection-- the lateral and septal walls of the dominant ventricle in cases of a single RV or LV and both the lateral LV and RV walls in the presence of an unrestrictive ventricular septal defect and biventricular mass, such as an unbalanced AV septal defect. Statistical analysis using SPSS reported the median with interquartile range (IQR) and utilized Spearman or Pearson correlation testing as appropriate (P < 0.05 significant).

  Results

  Stage I palliation was performed in 29/30 (14 Norwood, 8 BT shunt, 5 PA bands, and 2 hybrids). GLS correlated with weight for age z-score (WAZ) scores (r= -0.45, p= 0.01) and trended toward correlation with weight for length z-score (r=-0.31, p =0.09) in this small study. Multivariate regression model using GLS as the dependent variable against WAZ score and atrioventricular regurgitation revealed an independent association between GLS and WAZ score (p=0.03) while the association of GLS with atrioventricular valve regurgitation lost significance (p=0.06). On ANOVA analysis of GLS based on ventricular morphology, GLS was diminished in the single RV subgroup [median -13.1% IQR (-15, -10.7)] compared to GLS in single LV [-17.2% (-21, -12.5)] and biventricular [-17.2% (-18.1, -14)] subgroups (p=0.043).

  Conclusion

  Lower WAZ-scores at the time of neonatal discharge are associated with lower GLS. Systemic right ventricles have lower GLS.

  Longitudinal analysis of myocardial function using strain in patients receiving cardiotoxic chemotherapy

  Anmol Goyal, Amulya Buddhavarapu, Kayla Simpson, Nataliya Kibiryeva, Wendy Hein, Joy M. Fulbright, and Sanket Shah

  Background:

  Chemotherapy-related cardiotoxicity (CTRC) is associated with significant morbidity and mortality in long-term cancer survivors. Left ventricular [LV] Global longitudinal strain (GLS) is a sensitive parameter that can be used for earlier detection of contractile function changes in these patients. Recent literature suggested certain genotypes may influence CTRC. Our goal was to assess longitudinal myocardial function and identify any correlation between certain genetic variations and LV function regarding CTRC in our pediatric population.

  Methods:

  50 subjects ≥10 years of age who have survived >2 years after completion of cancer treatment were enrolled out of which 29 subjects agreed for genetic analysis and follow-up evaluation of echocardiograms. Echocardiographic data from these 29 subjects was reviewed. Apical 4 chamber and short axis at the level of papillary muscles were used for area-length 2D Ejection fraction (EF) [bullet method], and apical 4 chamber image was used for GLS. GLS was performed by using speckle tracing retrospectively with 2D STE offline analysis software (4D LV-Analysis 3) developed by TomTec Imaging Systems. Seventeen of these 29 patients had longitudinal echocardiographic data available for serial measurement of their EF and GLS. GLS ≤-18% was considered normal. Paired t-test analysis was performed for these patients with follow-up data available using SPSS statistics 27.0. All 29 patients underwent whole exome sequencing for genetic polymorphism, the results of which are pending at the time of submitting this abstract.

  Results:

  Baseline GLS was normal in 28/29 patients (96.5%). Mean GLS was -21.71% ± 2.36 %. Mean EF was 60.1% ± 5.4%. Mean follow-up duration was 4.1 years [range 2.2-6.5 years]. At follow-up evaluation, the mean reduction of strain was 1.4 % [standard deviation (SD) of 2.1, p = 0.015] and reduction of EF was 1% [SD of 5.6, p=0.45]. Longitudinal data in 17 patients showed a decrease in GLS by >2% in 47 % of patients, however, only 11.7% of the patients had a concomitant significant decrease in EF of ≥5%.

  Conclusions:

  In this cohort of pediatric cancer patients, clinically all were asymptomatic; in New York Heart Association Heart failure class 1. With a mean follow-up period of 4 years, there was statistically significant reduction in GLS while EF essentially remained stable. GLS can be a more sensitive marker to assess longitudinal ventricular function than EF and can be a valuable tool in risk-stratifying patient receiving cardiotoxic chemotherapy. Additional multi-center longitudinal studies evaluating the long-term prognostic implications of reduced LV GLS in this population are essential.

  Transient Tricuspid Valvulitis: Another Brief Casualty of COVID-19 in Children

  Amulya Buddhavarapu, Girish S. Shirali, Stephen Kaine, and Doaa Aly

  Clinical Presentation:

  We discuss 3 patients, 8-10 years old, with significant tricuspid valve dysfunction during initial days of admission for multi-system inflammatory syndrome in children (MIS-C) associated with coronavirus 2019 (COVID-19) infection.

  All 3 patients had COVID antibodies and presented in uncompensated shock needing aggressive fluid resuscitation and vasoactive support. Elevated acute inflammatory markers, acute kidney injury (2/3 patients), troponin leak and repolarization abnormality on ECG were present on admission and resolved by discharge. All were treated with intravenous immunoglobulin (IVIG) infusion, high-dose steroids and prophylactic low molecular weight heparin. They were discharged home on aspirin and steroid taper.

  All patients had depressed left ventricular systolic function with LVEF of 38-52% and trivial to mild mitral regurgitation. Following fluid resuscitation and administration of IVIG, all patients developed moderate to severe, new-onset tricuspid valve regurgitation (TR) with failure of leaflet coaptation and normal tricuspid regurgitation velocities, with a TR vena contracta of 6-9 mm. Right ventricular (RV) systolic function as measured by fraction area change and TAPSE ranged from low normal to moderately decreased. RV size and tricuspid annular diameter Z score was normal for all patients.

  All 3 patients responded to diuresis and fluid restriction and had mild TR at discharge.

  Imaging Findings:

  Our patients demonstrated an interesting pattern of early, acute onset, moderate to severe tricuspid valve regurgitation, with a wide gap of non-coaptation between the septal and anterior tricuspid valve leaflets leading to a broad central jet of TR. The degree of TR was disproportionate to the degree of RV systolic dysfunction or annular dilatation.

  Role of Imaging in Patient Care:

  We postulate that the etiology of tricuspid valve dysfunction is a combination of valvulitis / papillary muscle dysfunction, RV diastolic dysfunction and volume overload due to fluid resuscitation and IVIG. The frequency of these findings points to the need for judicious volume resuscitation and slower IVIG infusions in MIS-C.

  Summary/Discussion Points:

  TR associated with MIS-C in the pediatric population appears to be transient, and responsive to alterations in the patient’s volume status and inflammatory state. This is in contrast to adults, in whom TR with RV dysfunction has been identified as a predictor of mortality.

  A Deleterious EPHB4 Mutation Suppresses PROX1 Expression and Disrupts Lymphatic Development in Neonatal Non-immune Hydrops

  Gangaram Akangire, Heather Menden, Sheng Xia, Atif Ahmed, and Venkatesh Sampath

  Background: Non-immune hydrops fetalis is often a fatal condition and in 20% of cases related to lymphatic anomalies. Maldevelopment of lymphatic valves, atretic or absence of central lymphatic vessels has been described in hydrops fetalis, but the genetic basis of these anomalies remains undefined. Recent reports suggest that Ephrin type B receptor 4 (EPHB4) gene has a significant role in embryonic development of lymphatic system. To test the hypothesis that EPHB4 mutations can cause hydrops fetalis, we combined whole exome sequencing (WES) with functional and pathological analysis of an infant who succumbed to neonatal hydrops.
  
  
  Objective: To discover the possible mechanism of non-immune hydrops in EPHB4 variant by WES, histopathologic analysis and in vitro functional analysis of genetic mutation in human lung endothelial cells (HLEC).
  
  
  Design/Methods: 35-week, 4.11kg male infant developed hydrops prenatally requiring multiple thoracentesis postnatally due to bilateral chylous pleural effusions and ascites, and eventually succumbed to infection and immunodeficiency from T-lymphocyte depletion. WES was performed to identify genetic causes of non-immune hydrops. Immunohistochemistry (IHC) was performed on autopsy specimens of lung and intestinal tissue. In vitro functional analysis was done using HLEC, and immunoblotting used of investigating signaling events.
  
  
  Results: Magnetic resonance imaging (MRI) lymphangiogram showed complete absence of central lymphatic ducts (Figure 1). WES showed a rare heterozygous missense mutation in EPHB4 (p.Ala700Thr) that was maternally inherited. Autopsy revealed pulmonary lymphangiectasia, depletion of lymphoid tissue, and staphylococcus aureus in spleen. IHC showed loss of PROX1 expression (prospero homeobox protein 1) in large lymphatic channels in lung and small intestinal villi (Figure 2). In vitrofunctional studies showed the EPHB4 mutation resulted in loss of phosphorylation, decreased ERK phosphorylation and suppressed PROX1 expression, necessary for lymphatic valve development (Figure 3).
  
  Conclusion(s): We report a novel case of fatal non-immune hydrops with lymphatic anomalies associated with an EPHB4functional mutation that suppresses its phosphorylation and PROX1 expression. This report highlights the importance of screening for EPHB4 variant in infants with the diagnosis of non-immune hydrops fetalis and lymphatic anomalies. This discovery will trigger further studies to find genetic basis of non-immune hydrops and novel therapies for this fatal disease.

  A novel way to describe variation in antibiotic use

  Adrienne G. DePorre, Troy Richardson, Jason Newland, and Mark Neuman

  Background: A broader understanding of antibiotic variation can inform stewardship efforts. Diversity indices are frequently calculated in ecologic studies to measure the variety of species in a given habitat, however they have not yet been used to study variation in antibiotic use in the healthcare setting.
  
  
  Objective: To develop a novel assessment of antibiotic variation, based on the breadth of an antibiotic’s associated conditions as well as its use, measured by days of therapy (DOT).
  
  
  Design/Methods: We assessed antibiotic use in children aged 60 days-18 years hospitalized at a US Children’s hospital included in the Pediatric Health Information System (PHIS) database. We identified common antibiotics, defined as those that account for >1% of total antibiotic DOT at >80% of hospitals. An antibiotic diversity index (ADI) was calculated for each antibiotic at each hospital using the number of conditions and DOT to mimic the Shannon-Weiner entropy index, an index used in ecology to measure the complexity of an ecosystem. Hospital-level variation in antibiotic use was measured by the spread of ADI scores across hospitals relative to the mean ADI (i.e. coefficient of variation [CV]).
  
  
  Results: Table 1 shows commonly used antibiotics at 49 hospitals. Cefazolin has the highest mean ADI indicating it is used in the highest number of conditions. However, it also has the smallest CV indicating consistent use across hospitals. . Conversely, meropenem has a relatively small mean ADI but has the highest CV. This indicates that meropenem is used in a relatively small number of conditions but is used more variably across hospitals. Figure 1 shows the utility of the ADI to identify variation in distribution of both an antibiotic’s DOT and associated conditions. In most hospitals, use of cefazolin is focused consistently in 7-9 conditions while meropenem is used consistently across hospitals in 2-3 conditions.
  
  Conclusion(s): ADI is a novel tool to measure variability in antibiotic use across hospitals. Comparisons of ADIs highlight antibiotics associated with unequal patterns of use and their associated conditions.

  Antibiotic Durations for Skin and Soft Tissue Infections in Pediatric Urgent Care Clinics

  Megan Hamner, Amanda Nedved, Holly Austin, Donna Wyly, Alaina N. Burns, Diana King, Brian R. Lee, and Rana El Feghaly

  Background: Skin and soft tissue infections (SSTIs) are the second most common diagnosis leading to pediatric antibiotic prescriptions in the outpatient setting after respiratory diagnoses. However, most antibiotic stewardship programs have mainly focused on the latter. Children seen in the ambulatory setting for SSTIs often receive >7 days of antibiotics, although current society guidelines recommend 5-7 days for most diagnoses.
  
  
  Objective: To determine the baseline percentage of patients receiving antibiotic prescriptions for >7 days for SSTIs in urgent care clinics (UCC)s of a pediatric health system and to evaluate factors that influence providers towards longer durations.
  
  
  Design/Methods: We built a report that extracted patient encounters from the three UCCs based on International Classification of Diseases (ICD)-10 codes for common SSTIs including impetigo, abscesses, cellulitis, erysipelas, folliculitis, paronychia, and animal bites. Data was pulled from June 2019 through June 2020. The report included patient age, concomitant diagnoses, antibiotics prescribed and their duration. We excluded encounters if the patient was transferred to the emergency department or admitted, the patient was younger than 3 months of age, no antibiotics were prescribed, or if there was a concurrent infectious diagnosis affecting antibiotic duration. We sent a 22-question survey to UCC providers to understand prescribing habits particularly focusing on factors prompting administration of longer antibiotic courses.
  
  
  Results: From June 2019-June 2020, we reviewed 2,575 encounters; we excluded 208 of those (8%). 823 (35%) of patients received >7 days of antibiotics for SSTIs while 1181 (50%) received 5-7 days and 35 (1%) received <5 days of antibiotics. 328>(14%) received topical therapy only. Most common antibiotics prescribed included cephalexin, clindamycin, and trimethoprim-sulfamethoxazole. A mild improvement in the 5-7 days duration was noted through our study period (Figure 1). The survey was sent to 50 providers with 27 responding (54% response rate) (Tables 1 and 2). Barriers for shorter treatment courses included concern for acute rheumatic fever development, parental pressure, fear of complications, and accustomed antibiotic duration.
  
  Conclusion(s): A third of children with SSTIs in our UCCs receive long courses of antibiotics. A mild improvement noted in our study period may be due to existing antibiotic stewardship interventions. Specific provider concerns leading to overprescribing will be targeted by quality improvement efforts.

  A SMARTer Way to Round

  Charles Maloy, Adrienne G. DePorre, Erica Adams, Jessica Olson, Amber Hunley, and Darcy K. Weidemann

  Background: Communication is a key driver of health care outcomes. Poor communication practices contribute to sentinel safety events, poor family/patient experiences, and delays in care. Use of checklists in the healthcare setting is important to the development of high reliability and is increasingly common, however, the development and implementation of medical checklists for the standard patient floor are inadequately described.
  
  
  Objective: To develop a sustainable rounding checklist for multidisciplinary discussion of patient safety measures and clinical plans.
  
  
  Design/Methods: Key stakeholders in the rounding process (subspecialty and general pediatrics physicians, resident physician, bedside nurses, and nursing leadership) created a rounding checklist tool for use on a medical unit at our tertiary care children’s hospital. This checklist was modified from an existing checklist used in the pediatric intensive care unit. It focused on reducing harm, improving quality of care, and facilitating communication. To foster open communication within the multidisciplinary team and project sustainability, bedside nurses owned the task to prompt daily review of checklist items with the team during rounds. We developed badge buddies as an aid and an audit tool to assess checklist compliance. Compliance with checklist use was assessed by iterative Plan-Do-Study-Act (PDSA) cycles. Acceptability and usefulness of the checklist was measured by a 6 month-post implementation survey of nurses, residents, and staff.
  
  
  Results: A five-item checklist entitled SMART (Situational Awareness, Medications, Access, Routine, and Transition) was created (Figure 1). Daily audits showed between 75%-88% usage of the checklist during rounds (Figure 2). Our first PDSA cycle showed improved compliance with implementation of a streamlined audit tool. 29% of eligible providers completed the survey (n=51). 77% of respondents perceived communication improvement with SMART card usage with 4% disagreement. 66% reported vital patient care details were discussed that would otherwise have been missed. Only 2% found the checklist led to delays in patient care with a majority responding that checklist completion took 30-60 seconds.
  
  Conclusion(s): This project emphasizes the importance of multidisciplinary teams in development and implementation of a daily rounding checklist for a pediatric floor. We demonstrate the feasibility and acceptability of inserting a rounding checklist into the workflow of a multidisciplinary pediatric care team. Further study is needed to determine long-term effects on this initiative on process of care outcomes.

  Assessing the Effects of Social Determinants on Serious Safety Events

  Lisa L. Schroeder, Jessi Van Roekel, and John Cowden

  Background: We have long known that various social determinants of health (SDH) such as race, gender, socioeconomic status and others can affect health outcomes, such as readmission rates and mortality. To our knowledge, the impact of SDH on safety events has not been studied.
  
  
  Objective: We sought to understand the role that social determinants may play in contributing to safety events at our institution and to incorporate this information into the creation of corrective action items following the serious safety event.
  
  
  Design/Methods: The Clinical Safety team partnered with the Office of Equity and Diversity to develop a standard question regarding the potential influence of any SDH to be asked of each staff member interviewed after a potential serious safety event. The question was asked at the end of the interview and was read to maintain consistency. The question was modified early in the process based on feedback from the interviewers and the staff interviewed. All identified factors were collected, and the clinical safety team ultimately determined the likelihood that factors contributed to the adverse outcomes.
  
  
  Results: Over the first two and a half years, 129 interviews were conducted spanning 20 safety events. The question was asked in 101 (78%) of the interviews. It was asked more consistently as the project went on, with only 58% in interviewees being asked the first year and 90% thereafter. At least one social determinant was identified as potentially contributing to the safety event in 21 interviews (11 cases). In these cases, an average of 1.36 factors were identified (range 1-3). Language and socioeconomic status were the most frequently identified factors. Responses to the social determinants question were then considered throughout the Root Cause Analysis process, including the development of action items.
  
  Conclusion(s): By treating health equity as fundamental to patient safety, we integrated a question on the potential impact of SDH on safety events. Socialization to the process took time, but staff have now expressed increased awareness of the potential effects of social determinants. The consideration of impact of SDH on adverse events has informed the improvement team in their development of action items. The success of this project has led to the incorporation of health equity questions into other areas, including Performance Improvement, Evidence Based Practice, Patient Family Experience, and others. We hope to incorporate a similar question into the overall event reporting system to help inform future initiatives.

  Association Between ESA Dose and Blood Pressure in Pediatric Patients on Dialysis

  Heather A. Morgans, Judith Sebestyen VanSickle, Franz Schaefer, and Bradley A. Warady

  Background: Hypertension is a reported side effect of Erythropoiesis Stimulating Agents (ESAs), with a mechanism of action related to elevated hematocrit levels and direct vasopressor effects. Limited information exists on the relationship between ESA dosage and hypertension in children receiving maintenance dialysis.
  
  
  Objective: The primary aim of this study was to determine whether there is a significant correlation between ESA dose and blood pressure (BP) in pediatric patients on dialysis. The secondary aim was to determine confounding variables in relation to ESA dose and BP.
  
  
  Design/Methods: Data from the International Pediatric Dialysis Network (IPDN) database was used to retrospectively evaluate the association between ESA dose and BP. Data collected from January 2007 to September 2019 was analyzed. Systolic and diastolic BP measurements obtained at clinic visits were averaged and standardized based on age, height, and sex. ESA dose was measured in units/kg/week with Darbepoetin and continuous erythropoietin receptor activator (CERA) converted to equivalent units of Epogen. The confounding variables analyzed include hemoglobin level, BMI, dialysis modality, total fluid output (daily ultrafiltrate plus 24-hour urine output), number of antihypertensive medications, and use of growth hormone. Linear regression with Pearson correlation was used to analyze continuous variables.
  
  
  Results: A total of 3790 children were included in the analysis with a mean age of 11 years and 55.7% male. The mean prescribed dose of ESA was 192 units/kg/week. A significant positive correlation was noted between ESA dose and systolic BP (p < 0.001) although there was no significant correlation with diastolic BP (p=0.2). Further evaluation showed a significant negative correlation between ESA dose, total fluid output, and hemoglobin level in univariate and multivariate analysis, p < 0.001.
  
  Conclusion(s): The preliminary results from this study suggest that there may be a correlation between higher doses of ESAs and higher systolic BP in children receiving maintenance dialysis. Ongoing analysis of confounding variables will be helpful in determining the full correlation between ESA dose and BP.

  Atrial standstill in a pediatric patient with SCN5A mutation following procainamide challenge

  Anmol Goyal, Lindsey Malloy-Walton, and Christopher Follansbee

  Background: Atrial standstill (AS) is a rare arrhythmia characterized by absence of electrical and mechanical atrial activity associated with SCN5A channelopathy.

  Case: An 18 year old male with structurally normal heart, frequent sinus pauses, nonsustained atrial tachycardia and high-grade block was found to have SCN5A mutation c.3823G>A (p.Asp1275Asn). An electrophysiology study (EPS) with high density voltage mapping of the right atrium was done (Fig 1a). Nonsustained multifocal atrial tachycardia was induced without ablative targets (Fib 1b). Procainamide challenge was negative for Brugada, however induced AS (Fig 1c-d). No atrial capture could be achieved at maximal output. Empiric atrial lead positioning in the right atrial appendage was utilized based on prior atrial mapping (Fig 1e). AS resolved in <24 hours with resultant functioning of the atrial>lead.

  Decision-Making: SCN5A disease can have a variable phenotype ranging from asymptomatic to progressive AS. A detailed EP study with high density mapping should be considered to assess for viable atrial tissue prior to pacemaker implantation. Progressive disease may result in high thresholds, failure to capture or AS, and patients should be followed closely.

  Conclusion: SCN5A channelopathy can result in a unique phenotype that requires careful and serial evaluation by an electrophysiologist. As progressive AS can occur, a detailed EPS with high density atrial mapping should be considered when pacemaker implantation is required.

  CONGENITAL MITRAL VALVE REGURGITATION, THE DILEMMA OF REPAIR VERSUS REPLACEMENT

  Bianca Cherestal and Doaa Aly

  Background: Congenital mitral regurgitation is a rare condition and can be challenging to manage when presenting in the neonatal period.

  Case: Two week old male presented with poor weight gain, murmur and cardiomegaly on chest X-ray. Echocardiogram showed moderate to severe mitral regurgitation (MR) and suprasystemic pulmonary hypertension (PHN) (fig 1 a, b). The mitral valve (MV) leaflets were thickened and tethered with failure of central coaptation. PHN was classified as WHO I and II (due to persistent PHN of newborn and MR respectively). Inhaled nitric oxide, Enalapril and Furosemide were initiated. Cardiac catheterization revealed PVRi of 8.9 WU x m2 and CT was non-specific for lung parenchymal disease. Sildenafil and Flolan were added to reverse PHN prior to proceeding with MV repair. At 4 weeks of age he underwent mitral valvuloplasty which was complicated by severe MR and left heart failure (fig 1 c-d). Successful MV replacement with 17 mm St Jude mechanical valve was performed at 11 weeks (fig 1 e). PHN medications were weaned and patient is now ready for discharge.

  Decision Making: Patient presented with severe left heart failure and PHN secondary to severe congenital MR. MV intervention was indicated due to failed medical management. While MV replacement, can be a challenge, it was ultimately necessary given the severe post repair residual regurgitation.

  Conclusion: This case highlights the complexity of decision making for congenital MR, and the role of MV replacement in the case of failed repair.

  Constrictive Pericarditis After Repair of a Ruptured Sinus of Valsalva

  Sarah Studyvin and Sanket Shah

  Background: Constrictive pericarditis (CP) is a rare complication of cardiac surgery. We report a patient who developed CP after ruptured sinus of Valsalva (RSOV) repair.

  Case: A 23-year-old male presented with severe exertional dyspnea one year after RSOV repair. Echocardiogram showed thickened pericardium, ventricular septal bounce (Fig 1A), left atrial enlargement, diastolic hepatic flow reversal (Fig 1B), and trivial mitral regurgitation without stenosis. He underwent cardiac catheterization, which revealed elevated filling pressures (RVEDP 16 mmHg, LVEDP 18 mmHg), RVEDP/RVSP ratio < 0.5, and a low cardiac index (1.65 L/min/m2). Cardiac MRI on the same day confirmed pericardial thickening (Fig D) with paradoxic septal motion, dilated pulmonary veins (Fig 1F) and retrograde flow in the SVC.

  Decision‐making: Pericardiectomy of thickened and adherent pericardium was performed without the use of cardiopulmonary bypass. The central venous pressure decreased from 23 to 7 mmHg and TEE showed normal systolic function with less septal bounce posteroperatively. Pathology specimens of the pericardium exhibited fibrosis and mild chronic inflammation. He continued to do well off diuretics at one-month follow-up.

  Conclusion: Constrictive pericarditis is an uncommon complication of aortic root surgery. MRI is the ideal study to confirm the thickened pericardium and paradoxic septal motion in patients with suspected pericarditis. Cardiac catheterization can be performed to confirm the diagnosis.

  C-reactive protein values to predict sepsis-induced inflammatory response in premature infants

  Megan Tucker, Hung-Wen Yeh, Daniel K. Oh, and Venkatesh Sampath

  Background: C-reactive protein (CRP) is an inflammatory marker that has been recognized as a biomarker of the systemic inflammatory response in preterm neonates. We hypothesized that initial and peak CRP values would correlate with the degree of sepsis-induced acute lung injury (ALI) as measured by the pulmonary severity score (PSS).
  
  
  Objective: 1) Determine if confirmed (CF) sepsis events are associated with higher initial and peak CRP values than rule out (RO) sepsis events. 2) Investigate if initial and/or peak CRP correlates with severity of sepsis-induced ALI as measured by the PSS.
  
  
  Design/Methods: In this retrospective case control study, we included infants < 31 weeks gestational age and < 1500 grams with late onset sepsis and RO sepsis events (blood culture negative, antibiotics continued 48-72 hours (hr)). We collected initial CRP values at the time of sepsis diagnosis and the peak CRP value recorded during the treatment period. Sepsis subtypes were defined as blood culture positive (Cx+), necrotizing enterocolitis (NEC), urinary tract infection (UTI), and culture negative (Cx-) sepsis (blood culture negative; antibiotics > 6 days). We collected the PSS, a validated score for lung injury, at different time points during the sepsis events starting at 72hr before and up to 168hr after sepsis diagnosis.
  
  
  Results: We analyzed 211 CF and 123 RO sepsis events. Initial and peak CRP values were significantly higher in the CF sepsis group vs the RO sepsis group [median and interquartile range 1.8 (0.7, 4.5) vs. 0.6 (0.5-1.1), p <0.01 for initial values and 3.6 (0.8, 8.7) vs. 0.8 (0.5, 1.4), p < 0.01 for the peak values] (Figure 1). The changes from the initial CRP to the peak CRP were also greater in the CF sepsis events than in the RO events (F(1,335)=8.41, p value 0.004) (Figure 2). The relationship between PSS and CRP varied over time becoming more significant after sepsis diagnosis (F(7,1245)=2.77, p=0.0074) (Figure 3). Lastly, the changes from the initial to the peak CRP levels were different across sepsis subtypes with larger changes observed in the Cx+ and NEC groups than in UTI, Cx-, and RO sepsis (F(4,377)=2.92, p=0.02, Figure 4).
  
  Conclusion(s): These results indicate that CRP is significantly higher both initially and at peak values in infants with CF vs RO sepsis events. Furthermore, CRP values correlate with PSS over time suggesting that CRP is not only a marker for sepsis/systemic inflammatory response but can potentially predict the severity of sepsis-induced ALI.

  Developing a Breastfeeding Advocacy Agenda through Insight from Breastfeeding Experiences of Faculty Physicians

  Pooja French, Elizabeth Simpson, Courtney Winterer, Jodi Dickmeyer, and Sarah Stone

  Background: Despite forward progress in recent decades surrounding lactation support, physician mothers continue to face challenges in achieving their breastfeeding goals.
  
  
  Objective: We aimed to survey personal breastfeeding experiences of faculty physician mothers who recently breastfed to help formulate a robust breastfeeding advocacy agenda. We hypothesized finding high incidence modifiable factors related to lactation support could improve physician breastfeeding goal success and ultimately improve the overall breastfeeding experience.
  
  
  Design/Methods: An anonymous breastfeeding survey containing both quantitative and qualitative items was sent to female faculty physicians at an academic children’s hospital in 2020. Inclusion criteria included female faculty physicians who had given birth in the past 5 years. Of these, responses endorsing breastfeeding experience were analyzed.
  
  
  Results: Fifteen percent of respondents stated that they did not meet their breastfeeding goals. The most prevalent theme for both positive and negative factors in the qualitative analysis was pumping breast milk. Physician mothers provided key insight into a) how the job role that is specific to a physician impacts breastfeeding experience, b) the impact of their return to work on breastfeeding, and c) ideas for improved lactation support. A limitation of our study was assessment at an academic pediatric institution resulting in respondents comprised of pediatricians and pediatric subspecialists who may have increased knowledge of the AAP’s recommendations regarding breastfeeding.
  
  Conclusion(s): Our study highlights how differences in pumping experiences have a profound impact on the faculty physician’s perception of having either a positive or negative breastfeeding experience. Development of a more individualized breastfeeding support plan for each faculty physician, with attention to physical space and time accommodations for pump breaks is needed. We believe conversation surrounding lactation support between employer and the faculty physician should occur prior to maternity leave and continue at regular intervals upon return to monitor for changes in needs. This study echoes the need for ongoing efforts to improve maternal and infant health by advocating for faculty physicians who are providing breast milk for their child. Future studies should evaluate the benefit of advocacy and a detailed, individualized breastfeeding support plan developed as a result of this study.

  Differences in ED and Inpatient Utilization by Location of Primary Care: Co-location at a Head Start Center vs. Academic Primary Care Clinic Setting

  Rupal Gupta and Jeffrey D. Colvin

  Background: Children (ED) and inpatient utilization. Co-location of a primary care clinic within a Head Start center (HSC) includes nursing surveillance of classrooms and same-day primary care access, which allows students at the HSC to be seen immediately for acute care during the day. Consequently, co-location of primary care within a HSC may reduce barriers to acute care for those students, thereby lowering their ED and inpatient utilization.
  
  
  Objective: To compare ED and inpatient utilization of students from a HSC with co-located primary care to patients treated at an academic primary care clinic (APCC).
  
  
  Design/Methods: In this retrospective cross-sectional study, we compared ED and inpatient utilization from July 1, 2016 to June 30, 2019 for 278 children from a HSC with co-located primary care to a propensity score-matched comparison group of 810 patients receiving primary care at an APCC located 1.7 miles away. The main outcome was ED and inpatient utilization. ED utilization rate was dichotomized as <1/year and ≥1 visit/year. Inpatient utilization was dichotomized as 0 and ≥1 hospitalization during the study period. The main exposure was being a student at the HSC. A 3:1 comparison group was chosen using propensity score matching based on age, gender, race/ethnicity, language, and insurance type, with a strict match based on home census tract (i.e., every comparison patient lived in the same census tract as the matched HSC student). We used the X2test for bivariate analyses and logistic regression in our multivariable analyses.
  
  
  Results: HSC and APCC patients had similar demographic characteristics (Table 1). A lower percentage of HSC students had an average of ≥1 ED visits/year than the comparison group (53.6% vs. 64.6%, p=0.001) (Table 2). There were no differences in hospitalizations. In comparison to having ≥1 ED visit/year, HSC students had 55% higher adjusted odds of having /year compared to the APCC group (aOR 1.55 [95% CI: 1.17, 2.06] p=0.002). There continued to be no differences in hospitalizations in our adjusted analyses (aOR 1.12 [95% CI: 0.73, 1.72] p=0.59).
  
  Conclusion(s): Students from a HSC with co-located primary care had lower odds of having ≥1 ED visit/year compared to matched controls from an APCC. Future research should investigate cost differences, other health and developmental outcomes, and comparisons to private primary care practices.

  Educating Providers: Timely post-operative pain management in a Level IV Neonatal Intensive Care Unit (NICU)

  Jamesia Donato, Darian Younger, Rebecca Palmer, Denise Smith, Alexandra Oschman, Meredith Kopp, Daphne Reavey, and Eugenia K. Pallotto

  Background: NICU patients often encounter painful procedures and can have significant short and long-term consequences from inadequately treated pain. Ensuring adequate pharmacological and non-pharmacological pain management while minimizing associated risks is paramount. Our NICU is part of the Children’s Hospitals Neonatal Consortium “Erase Pain” collaborative to improve management of postop pain in neonates.
  
  
  Objective: SMART
  
  Aim: Increase the percentage of patients receiving acetaminophen within one hour after surgery to greater than 70% by July 2020.
  
  
  Design/Methods: A multidisciplinary team developed pain treatment algorithms and postop order plans to standardize the approach to postop pain management. Providers were educated about their role in eliminating postop pain through mandatory educational sessions. Expectations include discussing pain management plan on rounds and during pre and postop team handoffs, utilize standard pain treatment algorithms (Fig.1) and order plans (Fig. 2). The order plan prioritizes the acetaminophen order to STAT, to support administration within the first hour after return from surgery. Process measures include compliance with use of the post op pain algorithm and order plan. Baseline data was reviewed from January-July 2019 and post education data obtained August 2019-August 2020.
  
  
  Results: Provider compliance with the order plan improved from a baseline of 16.7% of patients before education to 77.3% after intervention. Acetaminophen was administered within the first hour postoperatively more often after provider education, improving from a baseline of 41% to 74.7%. The percentage of patients receiving acetaminophen within the first hour was greater than 70% by July 2020 which precisely achieved our SMART AIM, shifts our center line (Fig. 3 and Fig 4) and is attributed to correct use of the order plan and algorithm. The percentage of elevated pain scores, monitored as a balancing measure, increased during this time period. Opioid exposure review as a balancing measure is ongoing.
  
  Conclusion(s): Educating providers about the importance of discussing postop pain and administering multimodal analgesia is effective in improving ordering practices and timely acetaminophen administration. With an increase in the percentage of elevated pain scores, addressing additional system factors is needed for optimal post-op pain treatment. Future aims include investigating events contributing to delayed acetaminophen administration and implement interventions to improve pain management.
