Temperature Elevation During Neonatal and Pediatric Fixed Wing Transport in a Subtropic Climate: A Descriptive Study.

OBJECTIVE: We sought to describe the degree of temperature elevation (∆T) among children transported in a subtropical climate (Florida) via fixed wing aircraft and identify potential relationships between patient weight and ∆T. METHODS: We performed a retrospective cohort study in children < 18 years of age undergoing interfacility transport via fixed wing aircraft from January 2016 through July 2020. The study outcomes were ∆T, maximum patient temperature, ambient temperature, and heat index. Bivariate cohorts defined by patient weight (5 kg) were compared using Fisher exact, Student t-, and Wilcoxon rank sum analyses. Exploratory testing included receiver operator characteristic curve analyses and unadjusted logistic regression. RESULTS: Of the 58 children studied, 25 (43%) were ≤ 5 kg, and 33 (57%) were > 5 kg. Compared with children > 5 kg, those ≤ 5 kg had greater ∆T (0.8° ± 0.6°C vs. 0.2° ± 0.3°C), maximum patient temperature (37.3° ± 0.6°C vs. 36.8° ± 0.4°C), and proportion with ≥ 1°C ∆T (36% vs. 3%). No child > 5 kg had a temperature > 38°C, and no differences were observed for heat index or ambient temperature. Receiver operating characteristic analysis of patient weight on ∆T ≥ 1°C yielded an area under the curve of 0.86 (cutoff of 3.5 kg; sensitivity = 81.3%, specificity = 80%). Patient weight was inversely associated with ∆T ≥ 1°C (odds ratio = 0.69; 95% confidence interval, 0.49-0.96). CONCLUSIONS: Young children appear at greatest risk for developing environmental hyperthermia during interfacility fixed wing transport.

Improving Pediatric Readiness in General Emergency Departments: A Prospective Interventional Study.

OBJECTIVE: To describe the impact of a national interventional collaborative on pediatric readiness within general emergency departments (EDs). STUDY DESIGN: A prospective, multicenter, interventional study measured pediatric readiness in general EDs before and after participation in a pediatric readiness improvement intervention. Pediatric readiness was assessed using the weighted pediatric readiness score (WPRS) on a 100-point scale. The study protocol extended over 6 months and involved 3 phases: (1) a baseline on-site assessment of pediatric readiness and simulated quality of care; (2) pediatric readiness interventions; and (3) a follow-up on-site assessment of WPRS. The intervention phase included a benchmarking performance report, resources toolkits, and ongoing interactions between general EDs and academic medical centers. RESULTS: Thirty-six general EDs were enrolled, and 34 (94%) completed the study. Four EDs (11%) were located in Canada, and the rest were in the US. The mean improvement in WPRS was 16.3 (P < .001) from a baseline of 62.4 (SEM = 2.2) to 78.7 (SEM = 2.1), with significant improvement in the domains of administration/coordination of care; policies, protocol, and procedures; and quality improvement. Six EDs (17%) were fully adherent to the protocol timeline. CONCLUSIONS: Implementing a collaborative intervention model including simulation and quality improvement initiatives is associated with improvement in WPRS when disseminated to a diverse group of general EDs partnering with their regional pediatric academic medical centers. This work provides evidence that innovative collaboration facilitated by academic medical centers can serve as an effective strategy to improve pediatric readiness and processes of care.

Transcutaneous Carbon Dioxide Monitoring During Apnea Testing for Determination of Neurologic Death in Children: A Retrospective Case Series.

OBJECTIVES: Determination of neurologic death in children is a clinical diagnosis based on absence of neurologic function with irreversible coma and apnea. Apnea testing during determination of neurologic death assesses spontaneous respiration when PaCO2 increases to greater than or equal to 60 and greater than or equal to 20 mm Hg above pre-apneic baseline. The utility of transcutaneous carbon dioxide measurements during apnea testing in children is unknown. We seek to determine the degree of correlation between paired transcutaneous carbon dioxide and PaCO2 values during apnea testing for determination of neurologic death. DESIGN: Single-center, retrospective case series. SETTING: Twenty-eight bed PICU in a 259-bed, tertiary care, referral center. PATIENTS: Children 0-18 years old undergoing determination of neurologic death between May 2017 and December 2018. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Primary outcomes were paired transcutaneous carbon dioxide and PaCO2 values obtained during determination of neurologic death. Primary analyses included Pearson correlation coefficient, Bland-Altman bias and limits of agreement, and comparative statistics. Descriptive data included demographics, admission diagnoses, hemodynamics, Vasoactive Inotropic Scores, and arterial blood gas measurement. Eight children underwent 15 determination of neurologic death examinations resulting in 31 paired transcutaneous carbon dioxide and PaCO2 values for study. Transcutaneous carbon dioxide and PaCO2 correlated well (r = 0.94; p < 0.01). Bias between transcutaneous carbon dioxide and PaCO2 was -3.29 ± 7.14 mm Hg. Differences in means did not correlate with Vasoactive Inotropic Score (r = 0.2) or patient temperature (r = 0.11). Receiver operator characteristic curve of transcutaneous carbon dioxide after 3-10 minutes of apnea to discriminate positive apnea testing by the standard of PaCO2 yielded an area under the curve of 0.91 and threshold of greater than or equal to 64 mm Hg (sensitivity, 91.7%; specificity, 100%; positive predictive value, 100%; negative predictive value, 92.3%; accuracy, 95.9%). CONCLUSIONS: During apnea testing for determination of neurologic death in children, noninvasive transcutaneous carbon dioxide monitoring demonstrated high correlation, accuracy, and minimal bias when compared with PaCO2. Further validation is required before any recommendation to replace PaCO2 with noninvasive transcutaneous carbon dioxide monitoring can be proposed. However, concurrent transcutaneous carbon dioxide data may limit unnecessary apnea time and associated hemodynamic instability or respiratory decompensation by approximating goal arterial blood sampling to document target PaCO2.

A Longitudinal and Sustainability Assessment of Pediatric Interfacility Transport Handover Standardization.

INTRODUCTION: Standardization of interfacility transport handover is associated with improved shared mental model development, efficiency, and teaming. We sought to build upon previously published data by evaluating 1-year follow-up data, assessing face-validity, and describing sustainability. METHODS: We performed a pre-post, retrospective cohort study in a stand-alone, tertiary, pediatric referral center for children 0-18 years of age transported to our pediatric intensive care unit, neonatal intensive care unit, or emergency department from October 2016 to November 2017. Handover was standardized using multidisciplinary checklists, didactics, and simulation. Data were collected for three 8-week periods (preintervention, postintervention, and 1-year follow-up). Outcomes included shared mental model index (shared mental model congruence expressed as an index, percent congruence regarding healthcare data), teaming data (efficiency, attendance, interruptions, interdependence), and face validity (5-point, Likert scale questionnaires). Statistics included 1-way analysis of variance, Kruskal-Wallis, chi-square, and descriptive statistics. RESULTS: One hundred forty-eight handovers (50 preintervention, 50 postintervention, and 48 at 1-year) were observed in the emergency department (41%), pediatric intensive care unit (45%), and neonatal intensive care unit (14%). No differences were noted in demographics, diagnoses, PIM-3-ROM, length of stay, mortality, ventilation, or vasoactive use. Sustained improvements were observed in shared mental model congruence expressed as an index (38% to 82%), physician attendance (76% to 92%), punctuality (91.5% to 97.5%), interruptions (40% to 10%), provision of anticipatory guidance (42% to 85%), and handover summarization (42% to 85%, all P < 0.01). Efficiency was maintained throughout (mean duration 4.5 ± 2.1 minutes). Face validity data revealed handover satisfaction, effective communication, and perceived professionalism. CONCLUSIONS: Enhancements in teaming, shared mental model development, and face validity were achieved and sustained 1-year following handover standardization with only minimal reeducation during the study period.

Standardization of Pediatric Interfacility Transport Handover: Measuring the Development of a Shared Mental Model.

OBJECTIVES: To determine if standardization of pediatric interfacility transport handover is associated with the development of a prototypical shared mental model between healthcare providers. DESIGN: A single center, prepost, retrospective cohort study. SETTINGS: A 259-bed, tertiary care, pediatric referral center. PATIENTS: Children 0 to 18 years old transferred to our critical care units or emergency center from October 2016 to February 2017. INTERVENTIONS: Standardization of interfacility handover using a multidisciplinary checklist, didactic teaching, and simulation conducted midway through the study period. MEASUREMENTS AND MAIN RESULTS: The primary outcome was a shared mental model index defined as percent congruence among handover participants regarding key patient healthcare data including patient identification, diagnoses, transport interventions, immediate postadmission care plans, and anticipatory guidance for ongoing care. Secondary outcomes were handover comprehensiveness and teaming metrics such as efficiency, attendance, interruption frequency, and team member inclusion. During the study period, 100 transport handovers were observed of which 50 were preintervention and 50 post. A majority of handovers represented transfers to the emergency center (41%) or PICU (45%). There were no observable differences between prepost intervention cohorts by general characteristics, admission diagnoses, or severity of illness metrics including Pediatric Index of Mortality-3-Risk of Mortality, length of stay, mortality, frequency of invasive and noninvasive ventilation, and vasoactive use. The shared mental model index increased from 38% to 78% following standardization of handover. Attendance (76% vs 94%), punctuality (91.5% vs 98%), attention (82% vs 92%), summarization (42% vs 72%), and provision of anticipatory guidance (42% vs 58%) also improved. Efficiency was unchanged with a mean handover duration of 4 minutes in both cohorts. CONCLUSIONS: Considerable enhancements in handover quality, team participation, and the development of a shared mental model after standardization of interfacility transport handover were noted. These findings were achieved without compromising handover efficiency.
