Simulation-based operations testing in new neonatal healthcare environments.

In situ simulations, those conducted in the actual clinical environment, confer a high level of contextual fidelity and have been applied to the operations testing of new healthcare environments (HCE) to identify potential threats to patient, family and staff safety. By conducting simulation-based operations testing, these latent safety threats (LSTs) - which are weaknesses in communications, human factors, system process and technologies, and the way they are linked together - can be identified and corrected prior to moving patients into the new HCE. Simulation-based operations testing has extended to the neonatal HCE, as neonatal intensive care units (NICUs) transition from open-bay to single-family room design. In this section, we define LSTs, review simulation-based operations testing in new neonatal and perinatal HCEs, review challenges associated with conducting simulation-based operations testing, and briefly review pre-construction simulation-based user-centered design of new HCEs.

Laryngeal Mask Airway Clinical Use and Training: A Survey of North American Neonatal Health Care Professionals.

OBJECTIVE: The aim of this study was to explore North American neonatal health care professionals' (HCPs) experience, confidence, skill, and training with the laryngeal mask airway (LMA). STUDY DESIGN: This was a cross-sectional survey. RESULTS: The survey was completed by 2,159 HCPs from Canada and the United States. Seventy nine percent had no clinical experience with the LMA, and less than 20% considered the LMA an alternative to endotracheal intubation (EI). The majority had received LMA training; however, 28% of registered nurses, 18% of respiratory therapists, 17% of physicians, and 12% of midwives had never inserted an LMA in a mannequin. Less than a quarter of respondents agreed that the current biennial Neonatal Resuscitation Program instruction paradigm is sufficient for LMA training. All groups reported low confidence and skill with LMA insertion, and compared with all other groups, the respiratory therapists had the highest reported confidence and skill. CONCLUSION: This survey study, which is the first of its kind to include midwives, demonstrates that neonatal HCPs lack experience, confidence, skill, and training with the LMA, rarely use the device, and in general, do not consider the LMA as an alternative to EI. These findings contribute to, and support the findings of previous smaller studies, and in conjunction with the diminishing opportunities for EI, highlight the need for programs to emphasize the importance of the LMA for neonatal airway management and prioritize regular LMA training, with focus that parallels the importance placed on the skills of EI and mask ventilation. KEY POINTS: · Lack of training for laryngeal mask airway use in neonatal resuscitation.. · Neonatal health care professionals rarely use the laryngeal mask airway as an alternate airway device.. · Neonatal health care professionals lack confidence and skill with the laryngeal mask airway..

A new era of assessment for neonatal-perinatal medicine trainees: milestones 2.0.

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.

Qualitative analysis of latent safety threats uncovered by in situ simulation-based operations testing before moving into a single-family-room neonatal intensive care unit.

OBJECTIVES: We aimed to identify: (a) latent safety threats (LSTs) in a new neonatal intensive care unit (NICU) through simulation-based pre-occupancy operations testing, and (b) LSTs that remained unresolved 1-year post-occupancy. STUDY DESIGN: In this qualitative study, 111 healthcare professionals participated in patient care simulations and debriefings in a new NICU. Debriefing transcripts were inductively analyzed to characterize LSTs. Unresolved LSTs were identified 1 year after NICU occupancy. RESULTS: Thematic saturation was attained after analysis of nine debriefings. Four major themes affecting staff function and patient safety emerged from 305 threats: relay of information, workplace design, patient care processes, and patient family and staff focus. One-year post occupancy, 29 (9%) LSTs remained unresolved. CONCLUSION: Team debriefings of simulated patient events uncover LSTs that can largely be resolved before transitioning patient care into a new NICU. Understanding how LSTs interact provides a platform to develop viable strategies to mitigate patient safety risks.

Influence of own mother's milk on bronchopulmonary dysplasia and costs.

BACKGROUND: Human milk from the infant's mother (own mother's milk; OMM) feedings reduces the risk of several morbidities in very low birthweight (VLBW) infants, but limited data exist regarding its impact on bronchopulmonary dysplasia (BPD). OBJECTIVE: To prospectively study the impact of OMM received in the neonatal intensive care unit (NICU) on the risk of BPD and associated costs. DESIGN/METHODS: A 5-year prospective cohort study of the impact of OMM dose on growth, morbidity and NICU costs in VLBW infants. OMM dose was the proportion of enteral intake that consisted of OMM from birth to 36 weeks postmenstrual age (PMA) or discharge, whichever occurred first. BPD was defined as the receipt of oxygen and/or positive pressure ventilation at 36 weeks PMA. NICU costs included hospital and physician costs. RESULTS: The cohort consisted of 254 VLBW infants with mean birth weight 1027±257 g and gestational age 27.8±2.5 weeks. Multivariable logistic regression demonstrated a 9.5% reduction in the odds of BPD for every 10% increase in OMM dose (OR 0.905 (0.824 to 0.995)). After controlling for demographic and clinical factors, BPD was associated with an increase of US$41 929 in NICU costs. CONCLUSIONS: Increased dose of OMM feedings from birth to 36 weeks PMA was associated with a reduction in the odds of BPD in VLBW infants. Thus, high-dose OMM feeding may be an inexpensive, effective strategy to help reduce the risk of this costly multifactorial morbidity.

Glial activation links early-life seizures and long-term neurologic dysfunction: evidence using a small molecule inhibitor of proinflammatory cytokine upregulation.

PURPOSE: Early-life seizures increase vulnerability to subsequent neurologic insult. We tested the hypothesis that early-life seizures increase susceptibility to later neurologic injury by causing chronic glial activation. To determine the mechanisms by which glial activation may modulate neurologic injury, we examined both acute changes in proinflammatory cytokines and long-term changes in astrocyte and microglial activation and astrocyte glutamate transporters in a "two-hit" model of kainic acid (KA)-induced seizures. METHODS: Postnatal day (P) 15 male rats were administered KA or phosphate buffered saline (PBS). On P45 animals either received a second treatment of KA or PBS. On P55, control (PBS-PBS), early-life seizure (KA-PBS), adult seizure (PBS-KA), and "two-hit" (KA-KA) groups were examined for astrocyte and microglial activation, alteration in glutamate transporters, and expression of the glial protein, clusterin. RESULTS: P15 seizures resulted in an acute increase in hippocampal levels of IL-1beta and S100B, followed by behavioral impairment and long-term increases in GFAP and S100B. Animals in the "two-hit" group showed greater microglial activation, neurologic injury, and susceptibility to seizures compared to the adult seizure group. Glutamate transporters increased following seizures but did not differ between these two groups. Treatment with Minozac, a small molecule inhibitor of proinflammatory cytokine upregulation, following early-life seizures prevented both the long-term increase in activated glia and the associated behavioral impairment. CONCLUSIONS: These data suggest that glial activation following early-life seizures results in increased susceptibility to seizures in adulthood, in part through priming microglia and enhanced microglial activation. Glial activation may be a novel therapeutic target in pediatric epilepsy.

Pulmonary function in bronchopulmonary dysplasia.

The purpose of this study was to examine lung function and bronchodilator responsiveness in infants with a history of prematurity and bronchopulmonary dysplasia (BPD), using the raised volume rapid thoracoabdominal compression technique as well as with whole-body plethysmography. Spirometric measurements were obtained in 28 infants with a history of BPD, defined as preterm birth with O2 requirement at 36 weeks postmenstrual age (gestational age at birth, 26.4 +/- 2.1 weeks, mean +/- SD; birthweight, 898 +/- 353 g; age at study, 68.0 +/- 35.6 weeks). Fractional lung volumes were measured in 27 subjects. Values were expressed as percentage of predicted normal values. Compared to normal infants, those with a history of BPD exhibited decreases in forced expiratory flows including forced expiratory volume in 0.5 sec (76.3 +/- 19.6%), forced expiratory flow at 75% of expired forced vital capacity (FEF75; 59.5 +/- 30.7%), and FEF(25-75) (74.0 +/- 26.8%; P<0.01 for all). Functional residual capacity (107.9 +/- 25.3%), residual volume (RV, 124.5 +/- 42.7%), and RV/total lung capacity (RV/TLC, 128.2 +/- 35.3%) were increased in infants with a history of BPD (P<0.05 for each). There was no difference in TLC between groups. Seventeen infants were studied both pre- and postalbuterol, and 6 (35%) demonstrated significant bronchodilator responsiveness. Infants with recurrent wheezing showed greater expiratory flow limitation, hyperinflation, and airways responsiveness, whereas those without wheezing showed only modest airway dysfunction. We conclude that infants with a history of BPD have pulmonary function abnormalities characterized by mild to moderate airflow obstruction and air trapping.
