Consensus on an implicit bias and health disparities curriculum in neonatal medicine: a Delphi study.

OBJECTIVE: Despite longstanding and recurrent calls for effective implicit bias (IB) education in health professions education as one mechanism to reduce ongoing racism and health disparities, such curricula for neonatal-perinatal medicine (NPM) are limited. We aim to determine the key curricular elements for educating NPM fellows, advanced practice providers, and attending physicians in the critical topics of IB and health disparities. STUDY DESIGN: A modified Delphi study was performed with content experts in IB and health disparities who had educational relationships to those working and training in the neonatal intensive care unit. RESULT: Three Delphi rounds were conducted from May to November 2021. Experts reached consensus on a variety of items for inclusion in the curriculum, including educational goals, learning objectives, teaching strategies, and educator principles. CONCLUSION: Essential curricular components of an IB and health disparities curriculum for neonatal medicine were defined using rigorous consensus building methodology.

Flipping the Teachers: Impact of a Standardized Physiology Curriculum on Neonatology Medical Educators.

OBJECTIVE: Academic physicians must teach elements in an Accreditation Council for Graduate Medical Education (ACGME)-mandated curriculum while balancing career development and clinical workload. Exploring educator perceptions on the learning environment and comparing two instructional methods (traditional didactics [TD] vs. flipped classroom [FC]) in one pediatric subspecialty may elucidate current challenges, barriers, and strategies to optimize learning and educator satisfaction. STUDY DESIGN: A randomized trial comparing effectiveness and learner preference for FC versus TD physiology teaching was conducted in ACGME-accredited neonatal-perinatal medicine (NPM) fellowship programs in 2018 to 2019. Educator preferences were elicited through online surveys pre- and postintervention. Free-text comments were provided for questions exploring strengths, challenges, and opportunities in fellowship education. Statistical analysis included comparisons of demographics and pre-post-intervention educator responses between groups. Thematic analysis of text responses was conducted to identify common subthemes. RESULTS: From 61 participating programs, 114 FC educators and 130 TD educators completed surveys. At baseline, all educators experienced professional satisfaction from teaching fellows, but noted challenges with time available to create and/or deliver educational content, limited content expertise amongst faculty, colleagues' limited enthusiasm toward educating fellows, and lack of perceived value of education by institutions given limited protected time or credit toward promotion. Postintervention, educators in both groups noted a preference to teach physiology using FC due to interactivity, learner enthusiasm, and learner-centeredness. FC educators had a 17% increase in preference to teach using FC (p = 0.001). Challenges with FC included ensuring adequate trainee preparation, protecting educational time, and providing educators with opportunities to develop facilitation skills. CONCLUSION: Overall, NPM educators in a trial evaluating a standardized, peer-reviewed curriculum report professional satisfaction from teaching, but described logistical challenges with developing/delivering content. Educators preferred instruction using FC, but identified challenges with learner preparedness and ensuring adequate educator time and skill. Future efforts should be dedicated to addressing these barriers. KEY POINTS: · Many challenges exist for educators teaching neonatal-perinatal medicine fellows, including time, support, and recognition.. · Many educators preferred using flipped classroom methodology with a standardized curriculum due to interactivity and learner-centeredness.. · Benefits of a standardized, peer-reviewed curriculum include reduced preparation time, adaptability of content, and learning environment enhancement..

Comparison of knowledge acquisition and retention following traditional didactic vs. flipped classroom education utilizing a standardized national curriculum: a randomized controlled trial.

OBJECTIVE: Measure the effectiveness of and preference for a standardized, national curriculum utilizing flipped classrooms (FC) in neonatal-perinatal medicine (NPM) fellowships. STUDY DESIGN: Multicentered equivalence, cluster randomized controlled trial of NPM fellowship programs randomized to receive standardized physiology education as in-class lectures (traditional didactic, TD arm) or as pre-class online videos followed by in-class discussions (FC arm). Four multiple-choice question quizzes and three surveys were administered to measure knowledge acquisition, retention, and educational preferences. RESULTS: 530 fellows from 61 NPM fellowships participated. Quiz performance was comparable between groups at all time points (p = NS, TD vs FC at 4 time points). Post intervention, more fellows in both groups preferred group discussions (pre/post FC 42% vs. 58%, P = 0.002; pre/post TD 43% vs. 60%, P = < 0.001). FC fellows were more likely to rate classroom effectiveness positively (FC/TD, 70% vs. 36%, P < 0.001). CONCLUSIONS: FCs promote knowledge acquisition and retention equivalent to TD and FC modalities are preferred by fellows.

Part 6: Essentials of Neonatal-Perinatal Medicine fellowship: program administration.

A successful Neonatal-Perinatal Medicine fellowship (NPM-F) program requires presence and insight of national and institutional supervisory organizations as well as effective program-specific leaders: program director (PD), associate program director (APD), program coordinator (PC), and core faculty. It is becoming more common for PDs and APDs to have advanced training in medical education and conduct medical education research. While NPM-F program leaders benefit from a strong national NPM educator community, they face challenges of increased regulatory burden and unclear national guidelines with variable local interpretation for protected time. National and local organizations can support program leaders and promote their academic success while reducing burnout and turnover by providing leadership training, academic mentoring, and adequate protected time for research and program-specific tasks.

Milestone Level Changes From Residency to Fellowship: A Multicenter Cohort Study.

BACKGROUND: A vital element of the Next Accreditation System is measuring and reporting educational Milestones. Little is known about changes in Milestones levels during the transition from residency to fellowship training. OBJECTIVE: Evaluate the Accreditation Council for Graduate Medical Education (ACGME) Milestones' ability to provide a linear trajectory of professional development from general pediatrics residency to neonatal-perinatal medicine (NPM) fellowship training. METHODS: We identified 11 subcompetencies that were the same for general pediatrics residency and NPM fellowship. We then extracted the last residency Milestone level and the first fellowship Milestone level for each subcompetency from the ACGME's Accreditation Data System on 89 subjects who started fellowship training between 2014 and 2018 at 6 NPM fellowship programs. Mixed-effects models were used to examine the intra-individual changes in Milestone scores between residency and fellowship after adjusting for the effects of the individual programs. RESULTS: A total of 1905 subcompetency Milestone levels were analyzed. The average first fellowship Milestone levels were significantly lower than the last residency Milestone levels (residency, mean 3.99 [SD = 0.48] vs fellowship 2.51 [SD = 0.56]; P < .001). Milestone levels decreased by an average of -1.49 (SD = 0.65) from the last residency to the first fellowship evaluation. Significant differences in Milestone levels were seen in both context-dependent subcompetencies (patient care and medical knowledge) and context-independent subcompetencies (professionalism). CONCLUSIONS: Contrary to providing a linear trajectory of professional development, we found that Milestone levels were reset when trainees transitioned from general pediatrics residency to NPM fellowship.

Outcomes in infants < 29 weeks of gestation following single-dose prophylactic indomethacin.

BACKGROUND: Prophylactic indomethacin (3 doses) decreases patent ductus arteriosus (PDA) and intraventricular hemorrhage (IVH) in preterm infants. The study aim was to determine whether single-dose indomethacin (SD-INDO) decreases PDA, IVH, and improves motor function. METHODS: A retrospective cohort (2007-2014) compared infants born < 29 weeks who did (n = 299) or did not (n = 85) receive SD-INDO and estimated outcomes association with ordinal logistic regression, adjusting for multiple variables using propensity scores. RESULTS: Infants who received SD-INDO were more premature (p < 0.001) but had lower odds of PDA (OR 0.26 [0.15, 0.44], p < 0.005), PDA receiving treatment (OR 0.12 [0.03, 0.47], p < 0.005), death (OR 0.41 [0.20, 0.86], p = 0.02), and CP severity (OR 0.33 [0.12, 0.89], p = 0.03). There was less IVH (OR 0.58 [0.36, 0.94], p = 0.03) when adjusted for gestational age. CONCLUSIONS: SD-INDO is associated with decreased PDA and CP severity and improved survival.

Value, Strengths, and Challenges of e-Learning Modules Paired with the Flipped Classroom for Graduate Medical Education: A Survey from the National Neonatology Curriculum.

OBJECTIVE: This study aimed to determine the value, strengths, and challenges of implementing an e-learning based flipped classroom (FC) educational modality as part of the standardized physiology National Neonatology Curriculum (NNC), created for neonatal-perinatal medicine (NPM) fellow learners and faculty educators. STUDY DESIGN: This is a cross-sectional study of NPM fellows and faculty educators who utilized at least one of the e-learning based NNC FC respiratory physiology programs between May and September 2018. Participants were surveyed anonymously regarding their experiences participating in the NNC, including measures of preparation time. A combination of descriptive statistics and proportion comparisons were used for data analysis. RESULTS: Among 172 respondents, the majority of fellow and faculty respondents reported positive attitudes toward the educational content and case discussions, and the majority supported national standardization of NPM physiology education (92%). Fellows reported greater preclass preparation for their FC compared with previous didactic lectures (30-60 vs. 0-15 minutes, p < 0.01). Faculty facilitators reported less preparation time before facilitating a FC compared with the time required for creating a new didactic lecture (median: 60 vs. 240 minutes, p < 0.01). Both fellows and faculty respondents preferred the FC approach to traditional didactics, with fellows showing a greater degree of preference than faculty (68 vs. 52%, respectively, p = 0.04). CONCLUSION: Fellows and faculty educators supported the FC learning, reporting peer-to-peer learning, and the establishment of a learning community which promotes adult learning and critical thinking skills. A national physiology curriculum creates equitable and engaging educational experiences for all NPM fellows while reducing individual program burden of content creation. Our findings further supported the development of an NNC using a flipped classroom modality.

Diagnosis and Management of Patent Ductus Arteriosus.

Preterm infants are at increased risk for patent ductus arteriosus (PDA). Prolonged exposure to PDA may be deleterious and has been associated with neonatal morbidity and mortality. Although the molecular mechanisms underlying regulation of postnatal ductus arteriosus closure are not fully understood, clinical experience and research trials have informed recent changes in PDA management strategies and refocused treatment strategies on smaller subsets of infants who require intervention. This review examines current diagnostic and management approaches to PDA in preterm neonates.

Flipping the classroom: a national pilot curriculum for physiology in neonatal-perinatal medicine.

OBJECTIVE: To explore interest, feasibility, perceived effectiveness, and acceptability of a standardized, national physiology curriculum for neonatal-perinatal medicine (NPM) fellows using online videos for knowledge acquisition paired with flipped classrooms (FCs) for knowledge application. STUDY DESIGN: Two educational programs pairing online videos with FCs were developed and peer-reviewed. These programs were piloted at five institutions. Fellows completed surveys, and fellows and educators participated in focus groups after their FC experiences. RESULTS: Thirty-five fellows responded to the survey. Forty-one fellows and six educators participated in focus groups. Fellows and educators preferred online videos paired with FCs over didactic teaching and perceived them to be effective for knowledge acquisition and application. CONCLUSION: Fellows and educators preferred FC learning over traditional didactics and reported that FCs facilitated creation of a learning community, fostering active learning. The favorable response toward this pilot project and the feasibility of its use supports further development of a standardized NPM physiology curriculum for fellowship training.

Cerebral regional oxygen saturation trends in infants with hypoxic-ischemic encephalopathy.

BACKGROUND: Neurological outcomes in neonatal hypoxic-ischemic encephalopathy (HIE) continue to be sub-optimal despite therapeutic hypothermia (TH). Cerebral near-infrared spectroscopy provides real-time regional oxygen saturation (CrSO2) that may be a marker of adverse MRI findings and neurodevelopmental outcomes. AIM: The aim of this study was to examine the value of CrSO2 monitoring in infants with HIE undergoing TH. STUDY DESIGN AND SUBJECTS: In this prospective study, CrSO2 was continuously recorded in 21 infants with HIE admitted for TH. OUTCOME MEASURES: Brain MRI signal abnormalities at 2weeks were scored in individual brain region and classified as none/mild, moderate and severe. 13 infants completed Bayley Scales of Infant Development (BSID) testing at 18-24months. RESULTS: Between 24 and 36h of life, there was a significant increase in odds of having moderate-severe brain MRI abnormalities with higher absolute CrSO2 values. Per 10% increase in absolute CrSO2, the odds ratio for moderate-severe brain MRI abnormalities was greatest at 30h (OR 3.78; confidence intervals (CI): 1.23-11.6, p=0.011). CrSO2 increased more rapidly in infants with greater injury seen on MRI (0.20/h for MRI scores 0/1, by 0.48/h for MRI score 2, and by 0.68/h for MRI score 3, p=0.05). At 30h, absolute CrSO2 correlated significantly with abnormal MRI findings in basal ganglia (92% vs. 78%, p=0.001), white matter (88% vs. 76%, p=0.01), posterior limb of internal capsule (92% vs. 78%, p=0.001), and brain stem (94% vs. 80%, p=0.03) but not with cortical injury (86% vs. 80%, p=0.17). Higher CrSO2 beyond 24h correlated with greater odds of worse BSID scores. CONCLUSIONS: Increasing CrSO2 is associated with moderate-severe brain injury as assessed by MRI. Higher absolute CrSO2 values during TH correlates with subcortical injury on MRI and poor neurodevelopmental outcomes in infants with HIE undergoing TH. CrSO2 can inform providers seeking early identification of patients at risk of worse injury who may benefit from further intervention.

Very low birth weight infant care: adherence to a new nutrition protocol improves growth outcomes and reduces infectious risk.

BACKGROUND: Very low birth weight (VLBW) infants are at risk for postnatal growth restriction due to inadequate nutrient delivery and concomitant illness. Integrated clinical pathways or protocols can improve growth outcomes by decreasing practice variability. METHODS: A comprehensive nutrition bundle comprising standardized recommendations for initiating, advancing, and fortifying enteral feedings, and timely discontinuation of central lines was implemented in July 2012. Eligible were infants with a birth weight of <1500 g and <34 weeks gestation who were born over a 1-year period pre- and post-intervention, respectively. The primary aim was to determine if the intervention improved anthropometric parameter delta z scores at 36 weeks PMA. Secondary aims included time to first and full enteral feedings, central line-days, and rates of necrotizing enterocolitis (NEC) and sepsis/sepsis-like episodes. RESULTS: A total of 299 infants were included, of which 156 received the proposed intervention (Nutrition bundle group), and 143 received non-standardized nutrition practices (Conventional group). Median delta z scores for length (-1.2 versus -1.71; p=0.01) and head circumference (-0.73 versus -1.21; p=0.03) but not weight at 36 weeks PMA (-1.42 versus -1.58; p=0.74) were significantly higher in the Nutrition bundle group as compared to the Conventional group. Fewer infants in the intervention group had severe growth restriction. Time to first feed, full feeds, and central line duration were significantly shorter in the intervention period. The incidence of NEC and sepsis/sepsis-like episodes decreased with the intervention. CONCLUSIONS: A strategy using a comprehensive nutrition bundle improved linear and head circumference growth, reduced postnatal growth restriction, and decreased comorbidities in VLBW infants.

Hypotension following patent ductus arteriosus ligation: the role of adrenal hormones.

OBJECTIVE: To test the hypothesis that an impaired adrenal response to stress might play a role in the hypotension that follows patent ductus arteriosus (PDA) ligation. STUDY DESIGN: We performed a multicenter study of infants born at <32 weeks' gestation who were about to undergo PDA ligation. Serum adrenal steroids were measured 3 times: before and after a cosyntropin (1.0 µg/kg) stimulation test (performed before the ligation), and at 10-12 hours after the ligation. A standardized approach for diagnosis and treatment of postoperative hypotension was followed at each site. A modified inotrope score (1 × dopamine [µg/kg/min] + 1 × dobutamine) was used to monitor the catecholamine support an infant received. Infants were considered to have catecholamine-resistant hypotension if their greatest inotrope score was >15. RESULTS: Of 95 infants enrolled, 43 (45%) developed hypotension and 14 (15%) developed catecholamine-resistant hypotension. Low postoperative cortisol levels were not associated with the overall incidence of hypotension after ligation. However, low cortisol levels were associated with the refractoriness of the hypotension to catecholamine treatment. In a multivariate analysis: the OR for developing catecholamine-resistant hypotension was OR 36.6, 95% CI 2.8-476, P = .006. Low cortisol levels (in infants with catecholamine-resistant hypotension) were not attributable to adrenal immaturity or impairment; their cortisol precursor concentrations were either low or unchanged, and their response to cosyntropin was similar to infants without catecholamine-resistant hypotension. CONCLUSION: Infants with low cortisol concentrations after PDA ligation are likely to develop postoperative catecholamine-resistant hypotension. We speculate that decreased adrenal stimulation, rather than an impaired adrenal response to stimulation, may account for the decreased production.

Superior mesenteric artery blood flow velocities following medical treatment of a patent ductus arteriosus.

We examined superior mesenteric artery blood flow velocity in response to feeding in infants randomized to trophic feeds (n = 16) or nil per os (n = 18) during previous treatment for patent ductus arteriosus. Blood flow velocity increased earlier in the fed infants, but was similar in the 2 groups at 30 minutes after feeding.

Enteral feeding during indomethacin and ibuprofen treatment of a patent ductus arteriosus.

OBJECTIVE: To test the hypothesis that infants who are just being introduced to enteral feedings will advance to full enteral nutrition at a faster rate if they receive "trophic" (15 mL/kg/d) enteral feedings while receiving indomethacin or ibuprofen treatment for patent ductus arteriosus. STUDY DESIGN: Infants were eligible for the study if they were 23(1/7)-30(6/7) weeks' gestation, weighed 401-1250 g at birth, received maximum enteral volumes ≤60 mL/kg/d, and were about to be treated with indomethacin or ibuprofen. A standardized "feeding advance regimen" and guidelines for managing feeding intolerance were followed at each site (N = 13). RESULTS: Infants (N = 177, 26.3 ± 1.9 weeks' mean ± SD gestation) were randomized at 6.5 ± 3.9 days to receive "trophic" feeds ("feeding" group, n = 81: indomethacin 80%, ibuprofen 20%) or no feeds ("fasting [nil per os]" group, n = 96: indomethacin 75%, ibuprofen 25%) during the drug administration period. Maximum daily enteral volumes before study entry were 14 ± 15 mL/kg/d. After drug treatment, infants randomized to the "feeding" arm required fewer days to reach the study's feeding volume end point (120 mL/kg/d). Although the enteral feeding end point was reached at an earlier postnatal age, the age at which central venous lines were removed did not differ between the 2 groups. There were no differences between the 2 groups in the incidence of infection, necrotizing enterocolitis, spontaneous intestinal perforation, or other neonatal morbidities. CONCLUSION: Infants required less time to reach the feeding volume end point if they were given "trophic" enteral feedings when they received indomethacin or ibuprofen treatments.

Evidence-based use of indomethacin and ibuprofen in the neonatal intensive care unit.

Indomethacin and ibuprofen are potent inhibitors of prostaglandin synthesis. Neonates have been exposed to these compounds for more than 3 decades. Indomethacin is commonly used to prevent intraventricular hemorrhage (IVH), and both drugs are prescribed for the treatment or prevention of patent ductus arteriosus (PDA). This review examines the basis for indomethacin and ibuprofen use in the neonatal intensive care population. Despite the call for restrained use of each drug, the most immature infants are likely to need pharmacologic approaches to reduce high-grade IVH, avoid the need for PDA ligation, and preserve the opportunity for an optimal outcome.

Evidence to inform decisions about maternal-fetal surgery: technical brief.

OBJECTIVE: To summarize the state of research in maternal-fetal surgery regarding the surgical repair of abnormalities in fetuses in the womb. DATA SOURCES: We searched MEDLINE from 1980 to 2010 for studies of maternal-fetal surgery for the following conditions: twin-twin transfusion syndrome, obstructive uropathy, congenital diaphragmatic hernia, myelomeningocele, thoracic lesions, cardiac malformations, and sacrococcygeal teratoma. METHODS OF STUDY SELECTION: We used pilot-tested data collection forms to screen publications for inclusion and to extract data. We compiled information about how fetal diagnoses were defined, maternal inclusion criteria, type of surgery, study design, country, setting, comparators used, length of follow-up, outcomes measured, and adverse events. TABULATION, INTEGRATION, AND RESULTS: Two reviewers independently extracted data and discordance was resolved by a third party. Of 1,341 articles located, we retained 258 (comprising 166 unique study populations). Three studies were randomized controlled trials; the majority of the evidence was observational (116 case series [70%], 36 retrospective [22%], and 11 prospective [7%] cohorts). Twin-twin transfusion is the most studied condition, with 84 studies including 2,532 pregnancies. Fewer than 500 pregnancies are represented in the literature for each of the other conditions except congenital diaphragmatic hernia (n=503). Inclusion criteria were poorly specified. Outcomes typically measured were survival to birth, preterm birth, and neonatal death. Longer-term outcomes were sparse but included pulmonary, renal, and neurologic status and developmental milestones. Maternal outcome data were rare. CONCLUSION: Although developing rapidly, maternal-fetal surgery research has yet to achieve the typical quality of studies and aggregate strength of evidence needed to optimally inform care.
