Performance of a Large Language Model on Practice Questions for the Neonatal Board Examination.

This Diagnostic/Prognostic Study evaluates the performance of a large language model in generating answers to practice questions for the neonatal-perinatal board examination.

Peri-mortem evaluation of infants who die without a diagnosis: focus on advances in genomic technology.

Infants who die within the first weeks to months of life may have genetic disorders, though many die without a confirmed diagnosis. Non-genetic conditions may also be responsible for unexplained infant deaths, and the diagnosis may be reliant upon studies performed in the peri-mortem period. Neonatologists, obstetricians, or pediatricians caring for these children and their families may be unsure of which investigations can and should be performed in the setting of a newborn or infant who is dying or has died. Recent advances in genomic sequencing technology may provide additional diagnostic options, though the interpretation of genetic variants discovered by this technique may be contingent upon clinical phenotype information that is obtained peri-mortem or upon autopsy. We have reviewed the current literature concerning the evaluation of an unexplained neonatal or infantile demise and synthesized a diagnostic approach, with a focus on the contribution of new and emerging genomic technologies.

Do-Not-Resuscitate Orders in the Neonatal ICU: Experiences and Beliefs Among Staff.

OBJECTIVES: Studies in adult patients have shown that do-not-resuscitate orders are often associated with decreased medical intervention. In neonatology, this phenomenon has not been investigated, and how do-not-resuscitate orders potentially affect clinical care is unknown. DESIGN: Retrospective medical record data review and staff survey responses about neonatal ICU do-not-resuscitate orders. SETTING: Four academic neonatal ICUs. SUBJECTS: Clinical staff members working in each neonatal ICU. INTERVENTIONS: Survey response collection and analysis. MEASUREMENTS AND MAIN RESULTS: Participating neonatal ICUs had 14-48 beds and 120-870 admissions/yr. Frequency range of do-not-resuscitate orders was 3-11 per year. Two-hundred fifty-seven surveys were completed (46% response). Fifty-nine percent of respondents were nurses; 20% were physicians. Over the 5-year period, 44% and 17% had discussed a do-not-resuscitate order one to five times and greater than or equal to 6 times, respectively. Fifty-seven percent and 22% had cared for one to five and greater than or equal to 6 patients with do-not-resuscitate orders, respectively. Neonatologists, trainees, and nurse practitioners were more likely to report receiving training in discussing do-not-resuscitate orders or caring for such patients compared with registered nurses and respiratory therapists (p < 0.001). Forty-one percent of respondents reported caring for an infant in whom interventions had been withheld after a do-not-resuscitate order had been placed without discussing the specific withholding with the family. Twenty-seven percent had taken care of an infant in whom interventions had been withdrawn under the same circumstances. Participants with previous experiences withholding or withdrawing interventions were more likely to agree that these actions are appropriate (p < 0.001). CONCLUSIONS: Most neonatal ICU staff report experience with do-not-resuscitate orders; however, many, particularly nurses and respiratory therapists, report no training in this area. Variable beliefs with respect to withholding and withdrawing care for patients with do-not-resuscitate orders exist among staff. Because neonatal ICU patients with do-not-resuscitate orders may ultimately survive, withholding or withdrawing interventions may have long-lasting effects, which may or may not coincide with familial intentions.

Frame-of-Reference Training: Establishing Reliable Assessment of Teaching Effectiveness.

INTRODUCTION: Frame-of-reference (FOR) training has been used successfully to teach faculty how to produce accurate and reliable workplace-based ratings when assessing a performance. We engaged 21 Harvard Medical School faculty members in our pilot and implementation studies to determine the effectiveness of using FOR training to assess health professionals' teaching performances. METHODS: All faculty were novices at rating their peers' teaching effectiveness. Before FOR training, we asked participants to evaluate a recorded lecture using a criterion-based peer assessment of medical lecturing instrument. At the start of training, we discussed the instrument and emphasized its precise behavioral standards. During training, participants practiced rating lectures and received immediate feedback on how well they categorized and scored performances as compared with expert-derived scores of the same lectures. At the conclusion of the training, we asked participants to rate a post-training recorded lecture to determine agreement with the experts' scores. RESULTS: Participants and experts had greater rating agreement for the post-training lecture compared with the pretraining lecture. Through this investigation, we determined that FOR training is a feasible method to teach faculty how to accurately and reliably assess medical lectures. DISCUSSION: Medical school instructors and continuing education presenters should have the opportunity to be observed and receive feedback from trained peer observers. Our results show that it is possible to use FOR rater training to teach peer observers how to accurately rate medical lectures. The process is time efficient and offers the prospect for assessment and feedback beyond traditional learner evaluation of instruction.

Fetal Physiology and the Transition to Extrauterine Life.

The physiology of the fetus is fundamentally different from the neonate, with both structural and functional distinctions. The fetus is well-adapted to the relatively hypoxemic intrauterine environment. The transition from intrauterine to extrauterine life requires rapid, complex, and well-orchestrated steps to ensure neonatal survival. This article explains the intrauterine physiology that allows the fetus to survive and then reviews the physiologic changes that occur during the transition to extrauterine life. Asphyxia fundamentally alters the physiology of transition and necessitates a thoughtful approach in the management of affected neonates.

Evaluation of a web-based portal to improve resident education by neonatology fellows.

BACKGROUND: Integration of web-based educational tools into medical training has been shown to increase accessibility of resources and optimize teaching. We developed a web-based educational portal (WBEP) to support teaching of pediatric residents about newborn medicine by neonatology fellows. OBJECTIVES: 1) To compare residents' attitudes about their fellow-led education in the NICU pre- and post-WBEP; including assessment of factors that impact their education and usefulness of teaching tools. 2) To compare fellow utilization of various teaching modalities pre- and post-WBEP. DESIGN/METHODS: We queried residents about their attitudes regarding fellow-led education efforts and various teaching modalities in the NICU and logistics potentially impacting effectiveness. Based on these data, we introduced the WBEP - a repository of teaching tools (e.g., mock code cases, board review questions, journal articles, case-based discussion scenarios) for use by fellows to supplement didactic sessions in a faculty-based curriculum. We surveyed residents about the effectiveness of fellow teaching pre- and post-WBEP implementation and the type of fellow-led teaching modalities that were used. RESULTS: After analysis of survey responses, we identified that residents cited fellow level of interest as the most important factor impacting their education. Post-implementation, residents described greater utilization of various teaching modalities by fellows, including an increase in use of mock codes (14% to 76%, p<0.0001) and journal articles (33% to 59%, p=0.02). CONCLUSIONS: A web-based resource that supplements traditional curricula led to greater utilization of various teaching modalities by fellows and may encourage fellow involvement in resident teaching.

Building collaborative teams in neonatal intensive care.

The complex multidisciplinary nature of neonatal intensive care combined with the numerous hand-offs occurring in this shift-based environment, requires efficient and clear communication and collaboration among staff to provide optimal care. However, the skills required to function as a team are not typically assessed, discussed, or even taught on a regular basis among neonatal personnel. We developed a multidisciplinary, small group, interactive workshop based on Team STEPPS to provide staff with formal teamwork skills, and to introduce new team-based practices; 129 (95%) of the eligible 136 staff were trained. We then compared the results of the pretraining survey (completed by 114 (84%) of staff) with the post-training survey (completed by 104 (81%) of participants) 2 years later. We found an improvement in the overall teamwork score from 7.37 to 8.08 (p=<0.0001) based on a range of poor (1) to excellent (9). Respondents provided higher ratings in 9 out of 15 team-based categories after the training. Specifically, staff found improvements in communication (p=0.037), placed greater importance on situation awareness (p=<0.00010), and reported that they supported each other more (p=<0.0001). Staff satisfaction was rated higher post-training, with responses showing that staff had greater job fulfilment (p=<0.0001), believed that their abilities were being utilised properly (p=0.003), and felt more respected (p=0.0037). 90% of staff found the new practice of team meetings to help increase awareness of unit acuity, and 77% of staff noted that they had asked for help or offered assistance because of information shared during these meetings. In addition to summarising the results of our training programme, this paper also provides practical tools that may be of use in developing team training programmes in other neonatal units.

Developing expert-derived rating standards for the peer assessment of lectures.

PURPOSE: For peer review of teaching to be credible and reliable, peer raters must be trained to identify and measure teaching behaviors accurately. Peer rater training, therefore, must be based on expert-derived rating standards of teaching performance. The authors sought to establish precise lecture rating standards for use in peer rater training at their school. METHOD: From 2008 to 2010, a panel of experts, who had previously helped to develop an instrument for the peer assessment of lecturing, met to observe, discuss, and rate 40 lectures, using a consensus-building model to determine key behaviors and levels of proficiency for each of the instrument's 11 criteria. During this process, the panelists supplemented the original instrument with precise behavioral descriptors of lecturing. The reliability of the derived rating standards was assessed by having the panelists score six sample lectures independently. RESULTS: Intraclass correlation coefficients of the panelists' ratings of the lectures ranged from 0.75 to 0.96. There was moderate to high positive association between 10 of the 11 instrument's criteria and the overall performance score (r = 0.752-0.886). There were no statistically significant differences among raters in terms of leniency or stringency of scores. CONCLUSIONS: Two relational themes, content and style, were identified within the instrument's variables. Recommendations for developing expert-derived ratings standards include using an interdisciplinary group for observation, discussion, and verbal identification of behaviors; asking members to consider views that contrast with their own; and noting key teaching behaviors for use in future peer rater training.

Lung injury and bronchopulmonary dysplasia in newborn infants.

Bronchopulmonary dysplasia is the most common morbidity among surviving premature infants. Injury to the developing lung is the result of the interaction between a susceptible host and a number of contributing factors such as mechanical ventilation and infection. The resulting persistent impairment of pulmonary function and need for ongoing therapy are the underlying characteristics of bronchopulmonary dysplasia. Important insights into the pathogenesis of bronchopulmonary dysplasia have led to numerous therapies and preventive approaches. Although significant progress has been made, in order to further affect the incidence and severity of the disease, we need to further study (a) the genetically determined predisposing factors, (b) the relative contribution of the various pathogenetic pathways, and, most important, (c) how to best translate the knowledge gained from these studies into effective clinical approaches.

Current concepts in intrauterine growth restriction.

Regulation of fetal growth is multifactorial and complex. Diverse factors, including intrinsic fetal conditions as well as maternal and environmental factors, can lead to intrauterine growth restriction (IUGR). The interaction of these factors governs the partitioning of nutrients and rate of fetal cellular proliferation and maturation. Although IUGR is probably a physiologic adaptive response to various stimuli, it is associated with distinct short- and long-term morbidities. Immediate morbidities include those associated with prematurity and inadequate nutrient reserve, while childhood morbidities relate to impaired maturation and disrupted organ development. Potential long-term effects of IUGR are debated and explained by the fetal programming hypothesis. In formulating a comprehensive approach to the management and follow-up of the growth-restricted fetus and infant, physicians should take into consideration the etiology, timing, and severity of IUGR. In addition, they should be cognizant of the immediate perinatal response of the growth-restricted infant as well as the childhood and long-term associated morbidities. A multi disciplinary approach is imperative, including early recognition and obstetrical management of IUGR, assessment of the growth-restricted newborn in the delivery room, possible monitoring in the neonatal intensive care unit, and appropriate pediatric follow-up. Future research is necessary to establish effective preventive, diagnostic, and therapeutic strategies for IUGR, perhaps affecting the health of future generations.
