Academic Half Day Improves Resident Perception of Education Without Compromising Patient Safety.

BACKGROUND: Residency programs are required to offer a didactic curriculum and protect resident time for education. Our institution implemented an academic half day (AHD) in the 2021-2022 academic year to address issues related to the standard noon conference series. OBJECTIVE: Determine the impact of AHD implementation on education, patient safety, and workflow. METHODS: This was a prospective, single-site educational intervention study. Pre- and post-implementation surveys and Accreditation Council for Graduate Medical Education (ACGME) surveys assessed changes in trainee and faculty attitudes and behaviors. Patient safety and workflow were evaluated by comparing the number of safety event reports, rapid response team activations, time to admission from the ED, and time of discharge on AHD days compared to other weekdays. RESULTS: Survey response rates were: residents 68%/48%, fellows 42%/35%, and faculty 59%/29%. AHD was associated with a significant, positive change in resident attitudes and experiences and on ACGME survey items. On AHDs compared with other weekdays, there were no significant differences in safety event report rates (P = .98), nor in rapid response team activation rates (P = .99). There was not a clinically meaningful difference in median admission time from the ED on AHD weekdays (125 minutes) compared to other weekdays (130 minutes, P = .04). There was no significant difference in median discharge time on AHD vs other weekdays (P = .13). CONCLUSIONS: This study suggests that there is no significant difference in patient safety or workflow with the implementation of AHD. This study supports prior studies that residents strongly prefer AHD. AHD may be a useful framework for resident education without compromising patient care.

Pediatric Faculty Engagement and Associated Areas of Worklife After a COVID19 Surge.

Purpose: Healthcare organizations strive to increase physician engagement and decrease attrition. However, little is known about which specific worklife areas may be targeted to improve physician engagement or retention, especially after stressful events such as a COVID19 surge. Our objective was to identify demographic characteristics and worklife areas most associated with increased physician engagement and decreased intent to leave in pediatric faculty. Patients and Methods: In September 2020, we conducted a cross-sectional survey of faculty at an academic, tertiary-care children's hospital. A convenience and voluntary sampling approach was used. The survey included demographics, Maslach Burnout Index-Human Services Survey (MBI-HSS) and the Areas of Worklife Survey (AWS). The MBI-HSS was used to measure faculty engagement. The AWS measures satisfaction with six worklife areas (workload, control, reward, fairness, community, values). We used bivariate analyses to examine relationships between worklife areas and engagement and between worklife areas and intent to leave. We included multivariate logistic regression models to examine worklife areas most associated with increased work engagement and decreased intent to leave. Results: Our response rate was 41% (113/274 participants). In bivariate analysis, engaged faculty reported higher satisfaction in all worklife areas. In multivariate analyses, positive perceptions of workload (odds ratio (OR) 2.83; 95% confidence interval (CI), 1.2-6.9), control (OR, 3.24; 95% CI 1.4-7.3), and community (OR, 6.07; 95% CI 1.9-18.7) were associated with engagement. Positive perceptions of values (OR, 0.07; 95% CI 0.02-0.32) and community (OR, 0.19; 95% CI 0.05-0.78) were negatively associated with intent to leave. Conclusion: We found that positive perceptions of workload, control, and community were most associated with engagement. Alignment of values and increased sense of community were associated with decreased intent to leave. Our findings suggest specific worklife areas may be targeted to increase faculty engagement and retention.

Retention of discharge instructions using an interdisciplinary model for at-risk children with cancer: A quality improvement initiative.

PURPOSE: We sought to improve caregiver retention of critical initial hospital discharge instructions using a multidisciplinary, team-based intervention for newly diagnosed pediatric cancer patients at high risk for unfavorable outcomes. MATERIALS AND METHODS: A multidisciplinary team of pediatric residents, nurses, social workers, pharmacists and hematology/oncology faculty implemented practices to optimize teaching of key discharge material as part of four Plan-Do-Study-Act intervention cycles. An 11-question survey distributed at the first post-discharge clinic visit assessed the efficacy of the intervention, as defined by caregiver retention of critical home instructions. RESULTS: Thirty-nine caregivers of pediatric cancer patients in an urban academic tertiary-care children's hospital took part in this project. Overall retention of key discharge information was greater in the post-intervention cohort compared to the baseline cohort (median total scores: 89 and 63, respectively; p = .001). Improvements in the proportions of correct responses post-intervention were also observed across all subject matters: from 0.57 to 0.88 for fever guidelines (p = .059), from 0.71 to 0.78 for signs of sepsis (p = .65), from 0.57 to 1.00 for accurate choice of on-call number (p = .004), and from 0.71 to 0.94 for antiemetic management (p = .14). CONCLUSION: Initiation of our comprehensive cancer-specific program to improve caregiver retention of discharge instructions at the first post-hospitalization clinic visit has been successful and sustainable. This project demonstrated that a multi-disciplinary collaborative team effort increases caregiver retention of critical health information, and this has potential to lead to improved outcomes for patients.

Acute asthma management with IV magnesium in obese, overweight and non-overweight inner-city children.

OBJECTIVE: IV Magnesium (IV Mg) is increasingly used as adjunctive therapy for asthma exacerbations. In obese patients, delays in recognition of asthma severity may lead to delays in IV Mg administration. Our objective was to examine whether timing of IV Mg administration varied by Body Mass Index (BMI) category and whether this relates to hospitalization course. METHODS: This is a retrospective chart review of IV Mg use for asthma in children 2-17 years of age hospitalized in an urban children's hospital. Weight status was categorized by BMI percentile for age. The primary outcome was time to IV Mg administration. Secondary outcomes included admission to the intensive care unit, time to discharge readiness and Length of Stay (LOS). Continuous variables were analyzed using Student's t-test or Mann-Whitney test, categorical variables with Chi-Square test or Fisher's exact test, as appropriate. A linear regression model examined factors related to time to IV Mg administration. RESULTS: In 2017, 361/698 (52%) of patients admitted with acute asthma received IV Mg. Of these, 210 patients met study criteria. Except for age, baseline characteristics did not vary by BMI category. No differences were found in Time to IV Mg, rates of admission to the intensive care unit, time to discharge readiness, or LOS comparing non-overweight to overweight or obese patients. CONCLUSIONS: In this sample of inner-city children who received IV Mg there were no differences in timing of IV Mg based on BMI category. Further work is needed to examine whether standardizing timing of IV Mg improves care.

Changes in Pediatric Faculty Burnout During the COVID-19 Pandemic.

OBJECTIVES: To examine the impact of the coronavirus disease 2019 (COVID-19) pandemic and associated workflow changes, such as deployment on pediatric faculty burnout in an early epicenter of the pandemic. We hypothesized burnout would increase during the COVID-19 surge. METHODS: We conducted serial cross-sectional surveys of pediatric faculty at an academic, tertiary-care children's hospital that experienced a COVID-19 surge in the Northeastern United States. Surveys were administered pre-surge (February 2020), during the surge (April 2020), and postsurge (September 2020). The primary outcome was burnout prevalence. We also measured areas of worklife scores. We compared responses between all 3 survey periods. Continuous variables were analyzed by using Student's t or Mann-Whitney tests, and categorical variables were analyzed by using χ2 or Fisher's exact test, as appropriate. RESULTS: Our response rate was 89 of 223 (40%) presurge, 100 of 267 (37%) during the surge, and 113 of 275 (41%) postsurge. There were no differences in demographics, including sex, race, and academic rank between survey periods. Frequency of burnout was similar in all 3 periods (20% to 26%). The mean scores of emotional exhaustion improved during the surge (2.25 to 1.9; P = .04). CONCLUSIONS: Contrary to our hypothesis, we found no changes in pediatric faculty burnout after a COVID-19 surge. Emotional exhaustion improved during the COVID-19 surge. However, these findings represent short-term responses to the COVID-19 surge. Longer-term monitoring of the impact of the COVID-19 surge on pediatric faculty burnout may be necessary for health care organizations to mitigate burnout.

SAFER Care: Improving Caregiver Comprehension of Discharge Instructions.

BACKGROUND: One in five pediatric patients suffers from adverse events related to hospital discharge. Current literature lacks evidence on effective interventions to improve caregiver comprehension (CC) of discharge instructions. We examined if a standardized framework for written and verbal discharge counseling was associated with increased CC of key discharge instructions after discharge from a general pediatric inpatient unit. METHODS: An interprofessional team created the SAFER Care framework to encourage standard, comprehensive discharge counseling. Plan-do-study-act cycles included electronic health record smartphrases, educational initiatives, data feedback, visual aids, and family outreach. Caregivers were surveyed by phone within 4 days of discharge. Our primary outcome was the proportion of caregivers correctly responding to all questions related to discharge care, comparing pre- and postintervention periods. Data were plotted on a statistical process control chart to assess the effectiveness of interventions. RESULTS: A total of 171 surveys were analyzed in the preintervention period, and 262 surveys were analyzed in the postintervention period. A total of 37% of caregivers correctly responded to all questions in the preintervention period, compared with 62% of caregivers in the postintervention period, meeting rules for special cause variation. CONCLUSIONS: Development of the SAFER Care framework and its use in written and verbal discharge counseling was associated with significantly improved CC of discharge instructions in a general pediatric inpatient unit. Further studies should be focused on expanding this to other populations, particularly limited-English-proficiency families.

Rapid Implementation of an Adult Coronavirus Disease 2019 Unit in a Children's Hospital.

OBJECTIVE: To describe the rapid implementation of an adult coronavirus disease 2019 (COVID-19) unit using pediatric physician and nurse providers in a children's hospital and to examine the characteristics and outcomes of the first 100 adult patients admitted. STUDY DESIGN: We describe our approach to surge-in-place at a children's hospital to meet the local demands of the COVID-19 pandemic. Instead of redeploying pediatric providers to work with internist-led teams throughout a medical center, pediatric physicians and nurses organized and staffed a 40-bed adult COVID-19 treatment unit within a children's hospital. We adapted internal medicine protocols, developed screening criteria to select appropriate patients for admission, and reorganized staffing and equipment to accommodate adult patients with COVID-19. We used patient counts and descriptive statistics to report sociodemographic, system, and clinical outcomes. RESULTS: The median patient age was 46 years; 69% were male. On admission, 78 (78%) required oxygen supplementation. During hospitalization, 13 (13%) eventually were intubated. Of the first 100 patients, 14 are still admitted to a medical unit, 6 are in the intensive care unit, 74 have been discharged, 4 died after transfer to the intensive care unit, and 2 died on the unit. The median length of stay for discharged or deceased patients was 4 days (IQR 2, 7). CONCLUSIONS: Our pediatric team screened, admitted, and cared for hospitalized adults by leveraging the familiarity of our system, adaptability of our staff, and high-quality infrastructure. This experience may be informative for other healthcare systems that will be redeploying pediatric providers and nurses to address a regional COVID-19 surge elsewhere.

Pleth Variability Index to Assess Course of Illness in Children with Asthma.

BACKGROUND: Status asthmaticus (SA) is a common reason for admission to the pediatric emergency department (ED). Assessing asthma severity efficiently in the ED can be challenging for clinicians. Adjunctive tools for the clinician have demonstrated inconsistent results. Studies have shown that pulsus paradoxus (PP) correlates with asthma severity. Pleth Variability Index (PVI) is a surrogate measure of PP. OBJECTIVE: We investigated whether PVI at triage correlates with disposition from the ED. METHODS: We recruited children aged 2-18 years old who presented to the pediatric ED of a tertiary care children's hospital with SA. PVI, Respiratory Severity Score, and vital signs were documented at triage and 2 hours into each patient's ED stay. PVI was measured using the Masimo Radical-7® monitor (Masimo Corp., Irvine, CA). RESULTS: Thirty-eight patients were recruited. Twenty-seven patients were discharged home, 10 patients were admitted to the general pediatrics floor and 1 patient was admitted to the intensive care unit. PVI values at triage did not correlate with disposition from the ED (p = 0.63). Additionally, when trending the change in PVI after 2 hours of therapy in the ED, no statistically significant patterns were demonstrated. CONCLUSIONS: Our study did not demonstrate a correlation between PVI and clinical course for asthmatics. PVI may be more clinically relevant in sicker children. Furthermore, it is possible that continuous monitoring of PVI may demonstrate more unique trends in relation to asthma severity versus single values of PVI. Additional studies are necessary to help clarify the relationship between PVI and the clinical course of children with SA.

Angiopoietin-like proteins stimulate HSPC development through interaction with notch receptor signaling.

Angiopoietin-like proteins (angptls) are capable of ex vivo expansion of mouse and human hematopoietic stem and progenitor cells (HSPCs). Despite this intriguing ability, their mechanism is unknown. In this study, we show that angptl2 overexpression is sufficient to expand definitive HSPCs in zebrafish embryos. Angptl1/2 are required for definitive hematopoiesis and vascular specification of the hemogenic endothelium. The loss-of-function phenotype is reminiscent of the notch mutant mindbomb (mib), and a strong genetic interaction occurs between angptls and notch. Overexpressing angptl2 rescues mib while overexpressing notch rescues angptl1/2 morphants. Gene expression studies in ANGPTL2-stimulated CD34(+) cells showed a strong MYC activation signature and myc overexpression in angptl1/2 morphants or mib restored HSPCs formation. ANGPTL2 can increase NOTCH activation in cultured cells and ANGPTL receptor interacted with NOTCH to regulate NOTCH cleavage. Together our data provide insight to the angptl-mediated notch activation through receptor interaction and subsequent activation of myc targets.

Zebrafish rhabdomyosarcoma reflects the developmental stage of oncogene expression during myogenesis.

Rhabdomyosarcoma is a pediatric malignancy thought to arise from the uncontrolled proliferation of myogenic cells. Here, we have generated models of rhabdomyosarcoma in the zebrafish by inducing oncogenic KRAS(G12D) expression at different stages during muscle development. Several zebrafish promoters were used, including the cdh15 and rag2 promoters, which drive gene expression in early muscle progenitors, and the mylz2 promoter, which is expressed in differentiating myoblasts. The tumors that developed differed in their ability to recapitulate normal myogenesis. cdh15:KRAS(G12D) and rag2:KRAS(G12D) fish developed tumors that displayed an inability to complete muscle differentiation as determined by histological appearance and gene expression analyses. By contrast, mylz2:KRAS(G12D) tumors more closely resembled mature skeletal muscle and were most similar to well-differentiated human rhabdomyosarcoma in terms of gene expression. mylz2:KRAS(G12D) fish showed significantly improved survival compared with cdh15:KRAS(G12D) and rag2:KRAS(G12D) fish. Tumor-propagating activity was enriched in myf5-expressing cell populations within all of the tumor types. Our results demonstrate that oncogenic KRAS(G12D) expression at different stages during muscle development has profound effects on the ability of tumor cells to recapitulate normal myogenesis, altering the tumorigenic capability of these cells.

The histone methyltransferase SETDB1 is recurrently amplified in melanoma and accelerates its onset.

The most common mutation in human melanoma, BRAF(V600E), activates the serine/threonine kinase BRAF and causes excessive activity in the mitogen-activated protein kinase pathway. BRAF(V600E) mutations are also present in benign melanocytic naevi, highlighting the importance of additional genetic alterations in the genesis of malignant tumours. Such changes include recurrent copy number variations that result in the amplification of oncogenes. For certain amplifications, the large number of genes in the interval has precluded an understanding of the cooperating oncogenic events. Here we have used a zebrafish melanoma model to test genes in a recurrently amplified region of chromosome 1 for the ability to cooperate with BRAF(V600E) and accelerate melanoma. SETDB1, an enzyme that methylates histone H3 on lysine 9 (H3K9), was found to accelerate melanoma formation significantly in zebrafish. Chromatin immunoprecipitation coupled with massively parallel DNA sequencing and gene expression analyses uncovered genes, including HOX genes, that are transcriptionally dysregulated in response to increased levels of SETDB1. Our studies establish SETDB1 as an oncogene in melanoma and underscore the role of chromatin factors in regulating tumorigenesis.

Melanocytes in development and cancer.

Melanocytes are pigment-producing cells in the skin of humans and other vertebrates. A number of genes involved in melanocyte development and vertebrate pigmentation have been characterized, largely through studies of a diversity of pigment mutations in a variety of species. Embryonic development of the melanocyte initiates with cell fate specification in the neural crest, which is then followed by cell migration and niche localization. Many genes involved in melanocyte development have also been implicated in the development of melanoma, an aggressive and fatal form of skin cancer that originates in the melanocyte. Although early stage melanomas that have not spread to the lymph nodes can be excised with little risk of recurrence, patients diagnosed with metastatic melanoma have a high mortality rate due to the resistance of most tumors to radiotherapy and chemotherapy. Transformed melanocytes that develop into melanomas proliferate abnormally and often begin to grow radially in the skin. Vertical growth can then follow this radial growth, leading to an invasion through the basement membrane into the underlying dermis and subsequent metastasis. It is still unclear, however, how a normal melanocyte becomes a melanoma cell, and how melanoma utilizes the properties of the normal melanocyte and its progenitors in its progression. The goal of this mini-review is to highlight the role of melanocyte developmental pathways in melanoma, and to discuss recent studies and tools being used to illuminate this connection.
