Gender and Authorship in Pediatric Critical Care Randomized Control Trials* Objectives: To examine the gender distribution of authorship of pediatric critical care randomized control trials. Data Sources: The 415 randomized control trials in pediatric critical care published before 2019. Study Selection: We included all randomized control trials enrolling children in a PICU. We used PICUtrials.net, which uses comprehensive search strategies of multiple databases, to identify published randomized control trials. Data Extraction: We manually extracted the name and profession of each listed author from each publication and classified each author as male or female based on their name. Results: We included 2,146 authors and were able to classify 1,888 (88%) as men or women. Overall, 38% of authors were women, this varied with the authorship position: 37% of first, 38% of middle, and 25% of last authors were women (p < 0.001). The three most common professions were physician (63%), nonclinician (11%), and nurse (6%)—of which 30%, 45%, and 97%, respectively, were women. The percentage of female authorship overall has increased from 28% in 1985–1989 to 39% in 2015–2018 (p for trend = 0.004). There were no significant differences in the characteristics of randomized control trials published with a female first or last author versus those with both male first and last authors with respect to the median number of children randomized (60 vs. 50; p = 0.41), multicentred trials (17% vs. 24%; p = 0.12), trials at low risk of bias (50% vs. 66%; p = 0.26), reporting any funding (55% vs. 51%; p = 0.66), or median number of citations per year (1.5 vs. 2.4; p = 0.09). Conclusions: Although increasing over time, the percentage of researchers publishing pediatric critical care randomized control trials who are women still lags behind the percentage clinicians who are women. Trials that female researchers publish are similar in characteristics and impact as male researchers. Further work should identify barriers to gender diversity and potential solutions in pediatric critical care research.

The New Trainee Effect in Tracheal Intubation Procedural Safety Across PICUs in North America: A Report From National Emergency Airway Registry for Children* Objectives: Tracheal intubation carries a high risk of adverse events. The current literature is unclear regarding the "New Trainee Effect" on tracheal intubation safety in the PICU. We evaluated the effect of the timing of the PICU fellow academic cycle on tracheal intubation associated events. We hypothesize 1) PICUs with pediatric critical care medicine fellowship programs have more adverse tracheal intubation associated events during the first quarter (July–September) of the academic year compared with the rest of the year and 2) tracheal intubation associated event rates and first attempt success performed by pediatric critical care medicine fellows improve through the 3-year clinical fellowship. Design: Retrospective cohort study. Setting: Thirty-seven North American PICUs participating in National Emergency Airway Registry for Children. Patients: All patients who underwent tracheal intubations in the PICU from July 2013 to June 2017. Interventions: None. Measurements and Main Results: The occurrence of any tracheal intubation associated events during the first quarter of the academic year (July–September) was compared with the rest in four different types of PICUs: PICUs with fellows and residents, PICUs with fellows only, PICUs with residents only, and PICUs without trainees. For the second hypothesis, tracheal intubations by critical care medicine fellows were categorized by training level and quarter for 3 years of fellowship (i.e., July–September of 1st yr pediatric critical care medicine fellowship = first quarter, October–December of 1st yr pediatric critical care medicine fellowship = second quarter, and April–June during 3rd year = 12th quarter). A total of 9,774 tracheal intubations were reported. Seven-thousand forty-seven tracheal intubations (72%) were from PICUs with fellows and residents, 525 (5%) with fellows only, 1,201 (12%) with residents only, and 1,001 (10%) with no trainees. There was no difference in the occurrence of tracheal intubation associated events in the first quarter versus the rest of the year (all PICUs: July–September 14.9% vs October–June 15.2%; p = 0.76). There was no difference between these two periods in each type of PICUs (all p ≥ 0.19). For tracheal intubations by critical care medicine fellows (n = 3,836), tracheal intubation associated events significantly decreased over the fellowship: second quarter odds ratio 0.64 (95% CI, 0.45–0.91), third quarter odds ratio 0.58 (95% CI, 0.42–0.82), and 12th quarter odds ratio 0.40 (95% CI, 0.24–0.67) using the first quarter as reference after adjusting for patient and device characteristics. First attempt success significantly improved during fellowship: second quarter odds ratio 1.39 (95% CI, 1.04–1.85), third quarter odds ratio 1.59 (95% CI, 1.20–2.09), and 12th quarter odds ratio 2.11 (95% CI, 1.42–3.14). Conclusions: The New Trainee Effect in tracheal intubation safety outcomes was not observed in various types of PICUs. There was a significant improvement in pediatric critical care medicine fellows' first attempt success and a significant decline in tracheal intubation associated event rates, indicating substantial skills acquisition throughout pediatric critical care medicine fellowship.

Clinical Signs to Categorize Shock and Target Vasoactive Medications in Warm Versus Cold Pediatric Septic Shock* Objectives: Determine level of agreement among clinical signs of shock type, identify which signs clinicians prioritize to determine shock type and select vasoactive medications, and test the association of shock type-vasoactive mismatch with prolonged organ dysfunction or death (complicated course). Design: Retrospective observational study. Setting: Single large academic PICU. Patients: Patients less than 18 years treated on a critical care sepsis pathway between 2012 and 2016. Interventions: None. Measurements and Main Results: Agreement among clinical signs (extremity temperature, capillary refill, pulse strength, pulse pressure, and diastolic blood pressure) was measured using Fleiss and Cohen's κ. Association of clinical signs with shock type and shock type-vasoactive mismatch (e.g., cold shock treated with vasopressor rather than inotrope) with complicated course was determined using multivariable logistic regression. Of 469 patients, clinicians determined 307 (65%) had warm and 162 (35%) had cold shock. Agreement across all clinical signs was low (κ, 0.25; 95% CI, 0.20–0.30), although agreement between extremity temperature, capillary refill, and pulse strength was better than with pulse pressure and diastolic blood pressure. Only extremity temperature (adjusted odds ratio, 26.6; 95% CI, 15.5–45.8), capillary refill (adjusted odds ratio, 15.7; 95% CI, 7.9–31.3), and pulse strength (adjusted odds ratio, 21.3; 95% CI, 8.6–52.7) were associated with clinician-documented shock type. Of the 86 patients initiated on vasoactive medications during the pathway, shock type was discordant from vasoactive medication (κ, 0.14; 95% CI, –0.03 to 0.31) and shock type-vasoactive mismatch was not associated with complicated course (adjusted odds ratio, 0.3; 95% CI, 0.1–1.02). Conclusions: Agreement was low among common clinical signs used to characterize shock type, with clinicians prioritizing extremity temperature, capillary refill, and pulse strength. Although clinician-assigned shock type was often discordant with vasoactive choice, shock type-vasoactive mismatch was not associated with complicated course. Categorizing shock based on clinical signs should be done cautiously.

The Impact of the Novel Coronavirus on Brazilian PICUs Objectives: To study the impact of the coronavirus disease 2019 pandemic, considering the physical distancing and schools closing, on the characteristics of admission and epidemiology on Brazilian PICUs. Design: Observational, multicenter, time series analysis, of electronic medical records from 15 PICU in Brazil. Data consisted of all March, April, and May PICU admissions from 2017 to 2020. Setting: Fifteen private PICUs in Brazil. Patients: Pediatric patients admitted to the PICU from March to May since 2017. Interventions: None. Measurements and Main Results: The period from March 11, 2020, to March 17, 2020, was considered the "intervention point" studied, corresponding to the suspension of school activities and the beginning of physical distancing in Brazil. During the pandemic period studied, there were 28 cases of coronavirus disease 2019 (one death). The mean age was higher (p = 0.000), the length of stay was shorter (p = 0.000), but mortality rates were similar among the periods (p = 0.36). The model estimated a reduction of 1,483 PICU admissions from March 2020 to May 2020. At the end of May, there was an estimated drop of –146.6 bronchiolitis admissions (95% CI, –242.8 to –50.3; p = 0.016); –71 asthma admissions (95% CI, –93.6 to –48.63; p = 0.000); and –59 community-acquired pneumonia admissions (95% CI, –74.7 to –43.3; p = 0.000) per period. The model showed no effect of the "intervention" (physical distancing) on hospitalization rates for epilepsy, diarrhea, sepsis, bacterial meningitis, or surgery when analyzed individually. When assessed together, the model estimated a reduction of 73.6 admissions (95% IC, –132 to –15.2; p = 0.43). Conclusions: The coronavirus disease 2019 pandemic strongly affected Brazilian PICUs, reducing admissions, length of stay, and the epidemiological profile. The measures to oppose the coronavirus disease 2019 pandemic may have prevented thousands of PICU hospitalizations across the country.

Nurse-Implemented Goal-Directed Strategy to Improve Pain and Sedation Management in a Pediatric Cardiac ICU Objectives: To assess the impact of a nurse-implemented goal-directed sedation strategy on patient care and nursing practice in a pediatric cardiac ICU. Design: Quality improvement project with a pre-post interval measurement plan. Setting: Thirty-one bed pediatric cardiac ICU in a freestanding tertiary care children's hospital. Patients: Postoperative pediatric cardiac surgery patients. Interventions: The implementation of cardiac-Randomized Evaluation of Sedation Titration for Respiratory Failure (RESTORE), a nurse-implemented goal directed strategy to improve pain and sedation management in a pediatric cardiac ICU which included daily team discussion of the patient's trajectory of illness (acute, titration, or weaning phase), prescription of a sedation target score based on the patient's trajectory of illness, arousal assessments, and opioid and/or sedative titration. Withdrawal Assessment Scores were used to assess and manage iatrogenic withdrawal symptoms. Measurements and Main Results: Data related to opioid and sedation use, pain and sedation scores, and the occurrence and management of iatrogenic withdrawal symptoms were reviewed on 1,243 patients during four separate time periods: one pre-implementation and three discontinuous post-implementation time intervals. Patient age and complexity were consistent across the data collection periods. Post-implementation opioids and benzodiazepines use was reduced about 50% without a concomitant increase in the use of other sedative classes. Few post-intervention patients were discharged from the pediatric cardiac ICU or to home on methadone (pediatric cardiac ICU: pre 19% to post 3%; hospital: pre 12% to post 1.3%). Documentation of pain, sedation, and withdrawal scores became more consistent and nurses reported satisfaction with their patient's comfort management. Conclusions: The implementation of a nurse-driven goal-directed plan such as cardiac-RESTORE to manage pediatric cardiac ICU patient pain and sedation is possible, sustainable, and associated with reduced sedative and methadone use.

Randomized Clinical Trial of 20% Mannitol Versus 3% Hypertonic Saline in Children With Raised Intracranial Pressure Due to Acute CNS Infections* Objectives: Mannitol is a commonly used osmotherapy agent in raised intracranial pressure. However, the side effects of mannitol are significant. In traumatic brain injury (adult and pediatric), hypertonic saline (3%) shows varied results in comparison with 20% mannitol. We compared the effect of 3% hypertonic saline versus 20% mannitol (using common dosing strategies) on raised intracranial pressure in pediatric acute CNS infections. Design: Open-label randomized controlled trial. Setting: PICU of a quaternary care academic institute. Patients: Children 1–12 years old, with raised intracranial pressure and modified-Glasgow Coma Scale scores less than or equal to 8, were enrolled. Interventions: Patients were randomly assigned to 20%-mannitol (n = 28), 0.5 gram/kg/dose versus 3%-hypertonic saline (n = 29), 10 mL/kg loading followed by 0.5–1 mL/kg/hr infusion. An intraparenchymal catheter was used to monitor the intracranial pressure. The primary outcome was the proportion of patients achieved target average intracranial pressure less than 20 mm Hg during 72 hours. Secondary outcomes were interventions, morbidity, and mortality. Measurements and Main Results: The proportion of patients with target average intracranial pressure (< 20 mm Hg) was higher in hypertonic saline-group as compared to mannitol-group (79.3% vs 53.6%; adjusted hazard ratio 2.63; 95% CI: 1.23–5.61). Mean (± se) reduction of intracranial pressure (–14.3 ± 1.7 vs –5.4 ± 1.7 mm Hg; p ≤ 0.001) and elevation of cerebral perfusion pressure (15.4 ± 2.4 vs 6 ± 2.4 mm Hg; p = 0.007) from baseline were significant in hypertonic saline-group. Mean (± se) intracranial pressure over 72 hours was lower (14 ± 2 vs 22 ± 2 mm Hg; p = 0.009), and cerebral perfusion pressure was higher (65 ± 2.2 vs 58 ± 2.2; p = 0.032) in hypertonic saline-group. Hypertonic saline-group had higher modified-Glasgow Coma Scale score at 72 hours (median, interquartile range 10; 7–11 vs 7; 3–9; p = 0.003), lower mortality (20.7% vs 35.7%; p = 0.21), shorter duration of mechanical ventilation (5 vs 15 d; p = 0.002), and PICU stay (11 vs 19 d; p = 0.016) and less severe neurodisability at discharge (31% vs 61%; p = 0.049). Conclusions: In pediatric acute CNS infections, 3%-hypertonic saline was associated with a greater reduction of intracranial pressure as compared to 20% mannitol.
