RESUMEN

BACKGROUND AND OBJECTIVES: Neonatal endotracheal tube (ETT) size recommendations are based on limited evidence. We sought to determine data-driven weight-based ETT sizes for infants undergoing tracheal intubation and to compare these with Neonatal Resuscitation Program (NRP) recommendations. METHODS: Retrospective multicenter cohort study from an international airway registry. We evaluated ETT size changes (downsizing to a smaller ETT during the procedure or upsizing to a larger ETT within 7 days) and risk of procedural adverse outcomes associated with first-attempt ETT size selection when stratifying the cohort into 200 g subgroups. RESULTS: Of 7293 intubations assessed, the initial ETT was downsized in 5.0% of encounters and upsized within 7 days in 1.5%. ETT downsizing was most common when NRP-recommended sizes were attempted in the following weight subgroups: 1000 to 1199 g with a 3.0 mm (12.6%) and 2000 to 2199 g with a 3.5 mm (17.1%). For infants in these 2 weight subgroups, selection of ETTs 0.5 mm smaller than NRP recommendations was independently associated with lower odds of adverse outcomes compared with NRP-recommended sizes. Among infants weighing 1000 to 1199 g: any tracheal intubation associated event, 20.8% with 2.5 mm versus 21.9% with 3.0 mm (adjusted OR [aOR] 0.62, 95% confidence interval [CI] 0.41-0.94); severe oxygen desaturation, 35.2% with 2.5 mm vs 52.9% with 3.0 mm (aOR 0.53, 95% CI 0.38-0.75). Among infants weighing 2000 to 2199 g: severe oxygen desaturation, 41% with 3.0 mm versus 56% with 3.5mm (aOR 0.55, 95% CI 0.34-0.89). CONCLUSIONS: For infants weighing 1000 to 1199 g and 2000 to 2199 g, the recommended ETT size was frequently downsized during the procedure, whereas 0.5 mm smaller ETT sizes were associated with fewer adverse events and were rarely upsized.

RESUMEN

Blended learning is a learner-centered educational method that combines online and traditional face-to-face educational strategies. Simulation is a commonly utilized platform for experiential learning and an ideal component of a blended learning curriculum. This section describes blended learning, including its strengths and limitations, educational frameworks, uses within health professions education, best practices, and challenges. Also included is a brief introduction to simulation-based education, along with theoretical and real-world examples of how simulation may be integrated into a blended learning curriculum. Examples of blended learning in Neonatal-Perinatal Medicine, specifically within the Neonatal Resuscitation Program, procedural skills training, and the National Neonatology Curriculum, are reviewed.

RESUMEN

Changes in neonatal intensive care unit (NICU) coverage models, restrictions in trainee work hours, and alterations to the training requirements of pediatric house staff have led to a rapid increase in utilization of front-line providers (FLPs) in the NICU. FLP describes a provider who cares for neonates and infants in the delivery room, nursery, and NICU, and includes nurse practitioners, physician assistants, and/or hospitalists. The increasing presence and responsibility of FLPs in the NICU have fundamentally changed the way patient care is provided as well as the learning environment for trainees. With these changes has come confusion over role clarity with resulting periodic conflict. While staffing changes have addressed a critical clinical gap, they have also highlighted areas for improvement amongst the teams of NICU providers. This paper describes the current landscape and summarizes improvement opportunities with a dynamic neonatal interprofessional provider team.

RESUMEN

To optimize post-graduate competency-based assessment for medical trainees, the Accreditation Council for Graduate Medical Education initiated a sub-specialty-specific revision of the existing Milestones 1.0 assessment framework in 2016. This effort was intended to increase both the effectiveness and accessibility of the assessment tools by incorporating specialty-specific performance expectations for medical knowledge and patient care competencies; decreasing item length and complexity; minimizing inconsistencies across specialties through the development of common "harmonized" milestones; and providing supplemental materials, including examples of expected behaviors at each developmental level, suggested assessment strategies, and relevant resources. This manuscript describes the efforts of the Neonatal-Perinatal Medicine Milestones 2.0 Working Group, outlines the overall intent of Milestones 2.0, compares the novel Milestones to the original version, and details the materials contained in the novel supplemental guide. This new tool should enhance NPM fellow assessment and professional development while maintaining consistent performance expectations across specialties.

RESUMEN

OBJECTIVE: This study aimed to identify barriers and facilitators of premedication utilization for nonemergent neonatal intubations (NIs) in a level IV neonatal intensive care unit (NICU). STUDY DESIGN: Between November 2018 and January 2019, multidisciplinary providers at a level IV NICU were invited to participate in an anonymous, electronic survey based on Theoretical Domains Framework to identify influences on utilization of evidence-based recommendations for NI premedication. RESULTS: Of 186 surveys distributed, 84 (45%) providers responded. Most agreed with premedication use in the following domains: professional role/identity (86%), emotions (79%), skills (72%), optimism (71%), and memory, attention, and decision process (71%). Domains with less agreement include social influences (42%), knowledge (57%), intention (60%), belief about capabilities (63%), and behavior regulation (64%). Additional barriers include environmental context and resources, and beliefs about consequences. CONCLUSION: Several factors influence premedication use for nonemergent NI and may serve as facilitators and/or barriers. Efforts to address barriers should incorporate a multidisciplinary approach to improve patient outcomes and decrease procedure-related pain. KEY POINTS: · Premedication for NIs can optimize conditions and decrease rates of tracheal intubation adverse events but there is significant international and institutional variation for premedication use for NI.. · Guided by implementation science methods, the Theoretical Domains Framework was utilized to construct a novel assessment tool to determine potential barriers to and facilitators of the use of premedication for NI.. · Several factors influence premedication for nonemergent NI..

RESUMEN

OBJECTIVE: Significant gaps exist in the pediatric resident (PR) procedural experience. Graduating PRs are not achieving competency in the 13 ACGME recommended procedures. It is unclear why PR are not able to achieve competency, or how existing gaps may be addressed. METHODS: We performed in-depth one-on-one semistructured interviews with 12 pediatric residency program directors (PPDs). The interviews were audio-recorded, and transcribed verbatim. Coding of the data using conventional content analysis led to generation of categories, which were validated through consensus development. RESULTS: We identified 4 main categories, including (1) programs struggle to ensure adequate training in procedural skills for PRs, with various barriers reported; (2) programs develop individualized strategies to address challenges in procedural skills training, and multiple options are necessary; (3) PPDs face challenges defining procedural competency and standardizing expectations; and (4) expectations for PR procedural training may require modification based upon current practice environments. Solutions include simulation, procedural boot camps, and procedural/subspecialty electives. CONCLUSIONS: Numerous methods to combat challenges in PR procedural training have been identified by participating PPDs, including simulation, tailoring electives, and developing institutional guidelines. However, accreditation bodies may need to update procedural expectations based on individual resident career goals and realities of current day practice.

RESUMEN

Background: Despite a recent rise in publications describing extracorporeal membrane oxygenation (ECMO) education, the scope and quality of ECMO educational research and curricular assessments have not previously been evaluated. Objective: The purposes of this study are 1) to categorize published ECMO educational scholarship according to Bloom's educational domains, learner groups, and content delivery methods; 2) to assess ECMO educational scholarship quality; and 3) to identify areas of focus for future curricular development and educational research. Methods: A multidisciplinary research team conducted a scoping review of ECMO literature published between January 2009 and October 2021 using established frameworks. The Medical Education Research Study Quality Instrument (MERSQI) was applied to assess quality. Results: A total of 1,028 references were retrieved; 36 were selected for review. ECMO education studies frequently targeted the cognitive domain (78%), with 17% of studies targeting the psychomotor domain alone and 33% of studies targeting combinations of the cognitive, psychomotor, and affective domains. Thirty-three studies qualified for MERSQI scoring, with a median score of 11 (interquartile range, 4; possible range, 5-18). Simulation-based training was used in 97%, with 50% of studies targeting physicians and one other discipline. Conclusion: ECMO education frequently incorporates simulation and spans all domains of Bloom's taxonomy. Overall, MERSQI scores for ECMO education studies are similar to those for other simulation-based medical education studies. However, developing assessment tools with multisource validity evidence and conducting multienvironment studies would strengthen future work. The creation of a collaborative ECMO educational network would increase standardization and reproducibility in ECMO training, ultimately improving patient outcomes.

RESUMEN

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..

RESUMEN

OBJECTIVE: To determine the relationship between number of attempts and adverse events during neonatal intubation. STUDY DESIGN: A retrospective study of prospectively collected data of intubations in the delivery room and NICU from the National Emergency Airway Registry for Neonates (NEAR4NEOS) in 17 academic centers from 1/2016 to 12/2019. We examined the association between tracheal intubation attempts [1, 2, and ≥3 (multiple attempts)] and clinical adverse outcomes (any tracheal intubation associated events (TIAE), severe TIAE, and severe oxygen desaturation). RESULTS: Of 7708 intubations, 1474 (22%) required ≥3 attempts. Patient, provider, and practice factors were associated with higher TI attempts. Increasing intubation attempts was independently associated with a higher risk for TIAE. The adjusted odds ratio for TIAE and severe oxygen desaturation were significantly higher in TIs with 2 and ≥3 attempts than with one attempt. CONCLUSION: The risk of adverse safety events during intubation increases with the number of intubation attempts.

RESUMEN

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.

RESUMEN

OBJECTIVE: Neonatal-perinatal medicine (NPM) fellowship programs in the United States support >800 learners annually. Understanding variations in the programmatic structure, challenges, and needs is essential to optimize the educational environment and ensure the specialty's future. STUDY DESIGN: NPM fellowship program directors (PDs) and associate program directors (APDs) were invited to complete an electronic survey on their program administration, recruitment, clinical training, assessment methods, scholarly program, and career pathways. Each participant identified individual programmatic strengths, challenges, opportunities, and threats to the field. RESULTS: Representatives from 59 NPM fellowships provided data (response rate 59/96 = 61%). In total, 30% of PDs received less than the Accreditation Council for Graduate Medical Education -recommended protected time for administrative duties, and 44% of APDs received no protected time. Fellow clinical service assignments varied widely from 13 to 18 months and 90 to 175 call nights over 3 years. Recruitment practices varied across programs; 59% of respondents raised concerns over the pipeline of applicants. Conflicts between fellows and advanced practice providers were identified by 61% of responders. Programs varied in their scholarly offerings, with 44% of NPM fellowships interested in adding broader research opportunities. CONCLUSIONS: NPM fellowship leaders identified a need for improved programmatic support, enhanced measures to assess competency, opportunities to strengthen scholarly programs, shared curricular resources, and strategies to balance education with clinical demands. PDs and APDs identified threats to the future of NPM training programs including the diminishing pipeline of applicants into neonatology, challenges with clinical exposure and competence, inadequate support for the educational mission, issues supporting high-quality scholarship, and fewer graduates pursuing physician-investigator pathways. National organizations and academic institutions should take action to address these challenges so that fellowships can optimally prepare graduates to meet their patients' needs. KEY POINTS: · Numerous challenges exist for current program directors in NPM including balancing clinical work with scholarly activities, accurately assessing competency, optimizing the culture of the learning environment, and ensuring that fellows are adequately prepared for a range of postgraduate positions.. · Significant variation exists across NPM fellowship programs in clinical service/calls assigned over 3 years of fellowship training, as well as opportunities to pursue scholarly activities across a variety of areas.. · Challenges exist related to ensuring an adequate number of future applicants into the specialty, including those from backgrounds traditionally underrepresented in medicine, as well as those seeking to pursue careers as physician-investigators..

RESUMEN

The clinical and academic landscape of Neonatal-Perinatal Medicine (NPM) is evolving. Career opportunities for neonatologists have been impacted by shifts in compensation and staffing needs in both academic and private settings. The workforce in NPM is changing with respect to age and gender. Recruiting candidates from backgrounds underrepresented in medicine is a priority. Developing flexible positions and ensuring equitable salaries is critically important. Professional niches including administration, education, research, and quality improvement provide many opportunities for scholarly pursuit. Challenges exist in recruiting, mentoring, funding, and retaining physician-scientists in NPM. Creative solutions are necessary to balance the needs of the NPM workforce with the growing numbers, locations, and complexity of patients. Addressing these challenges requires a multi-faceted approach including adapting educational curricula, supporting trainees in finding their niche, identifying novel ways to address work/life integration, and attracting candidates with both diverse backgrounds and academic interests.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Characteristics of neonatal tracheal intubations (TI) may vary between the neonatal intensive care unit (NICU) and delivery room (DR). The impact of the setting on TI outcomes is not well characterized. OBJECTIVE: The aim of this study was to define variation in neonatal TI practice between settings, and identify the association between setting and TI success and safety outcomes. DESIGN: This was a retrospective cohort study of TIs in the National Emergency Airway Registry for Neonates from October 2014 to September 2017. The setting (NICU vs. DR) was the exposure of interest. The outcomes were first attempt success, course success, success within 4 attempts, adverse TI-associated events, severe desaturation, and bradycardia. We compared TI characteristics and outcomes between settings in univariable analysis. Factors significant in univariable analysis (p < 0.1) were included in a logistic regression model, with adjustment for clustering by center, to identify the independent impact of the setting on TI outcomes. RESULTS: There were 3,145 TI encounters (2279 NICU, 866 DR) in 9 centers. Almost all baseline characteristics significantly varied between settings. First attempt success rates were 48% (NICU) and 46% (DR). In multivariable analysis, the setting was not associated with first attempt success. DR was associated with a higher adjusted OR (aOR) of success within 4 attempts (1.48, 95% CI 1.06-2.08) and a lower aOR for bradycardia (0.43, 95% CI 0.26-0.71). CONCLUSION: Significant differences in patient, provider, and practice characteristics exist between NICU and DR TIs. There is substantial room for improvement in first attempt success rates. These results suggest interventions to improve safety and success need to be targeted to the distinct setting.
