Objective To describe the clinical characteristics of children and adolescents admitted to intensive care with confirmed COVID-19. Method Prospective, multicenter, observational study, in 19 pediatric intensive care units. Patients aged 1 month to 19 years admitted consecutively (March–May 2020) were included. Demographic, clinical-epidemiological features, treatment, and outcomes were collected. Subgroups were compared according to comorbidities, age < 1 year, and need for invasive mechanical ventilation. A multivariable logistic regression model was used for predictors of severity. Results Seventy-nine patients were included (ten with multisystemic inflammatory syndrome). Median age 4 years; 54% male (multisystemic inflammatory syndrome, 80%); 41% had comorbidities (multisystemic inflammatory syndrome, 20%). Fever (76%), cough (51%), and tachypnea (50%) were common in both groups. Severe symptoms, gastrointestinal symptoms, and higher inflammatory markers were more frequent in multisystemic inflammatory syndrome. Interstitial lung infiltrates were common in both groups, but pleural effusion was more prevalent in the multisystemic inflammatory syndrome group (43% vs. 14%). Invasive mechanical ventilation was used in 18% (median 7.5 days); antibiotics, oseltamivir, and corticosteroids were used in 76%, 43%, and 23%, respectively, but not hydroxychloroquine. The median pediatric intensive care unit length-of-stay was five days; there were two deaths (3%) in the non- multisystemic inflammatory syndrome group. Patients with comorbidities were older and comorbidities were independently associated with the need for invasive mechanical ventilation (OR 5.5; 95% CI, 1.43–21.12; p = 0.01). Conclusions In Brazilian pediatric intensive care units, COVID-19 had low mortality, age less than 1 year was not associated with a worse prognosis, and patients with multisystemic inflammatory syndrome had more severe symptoms, higher inflammatory biomarkers, and a greater predominance of males, but only comorbidities and chronic diseases were independent predictors of severity.

MEASUREMENTS AND MAIN RESULTS:Of the 161 participating PICUs, 83% were in academic teaching hospitals and 42% were in free-standing children's hospitals. Median size was 16 beds (interquartile range, 10-24 beds). Only 15 PICUs (9%) had incorporated all six ABCDEF bundle components into routine practice. Standardized pain assessment (A) was the most common (91%), followed by family engagement (F, 88%) and routine sedation assessment (C) with validated scales (84%). Protocols for testing extubation readiness or conducting spontaneous breathing trials (B) were reported in 57%, with 34% reporting a ventilator weaning protocol. Routine delirium monitoring with a validated screening tool (D) was reported by 44% of PICUs, and 26% had a guideline, protocol, or policy for early exercise/mobility (E). Practices for spontaneous breathing trials were variable in 29% of Canadian PICUs versus greater than 50% in the other regions. Delirium monitoring was lowest in Brazilian PICUs (18%) versus greater than 40% in other regions, and family engagement was reported in 55% of European PICUs versus greater than 90% in other regions. CONCLUSIONS: ABCDEF bundle components have been adopted with substantial variability across regions. Additional research must rigorously evaluate the efficacy of specific elements with a focus on B, D, E, and full ABCDEF bundle implementation. Implementation science is needed to facilitate an understanding of the barriers to ABCDEF implementation and sustainability with a focus on specific cultural and regional differences.

Objectives: To determine current management of critically ill children and gather views regarding high flow nasal cannula therapy and to evaluate research priorities for a large prospective randomized controlled trial of noninvasive respiratory support in children. Design: Multinational cross-sectional questionnaire survey conducted in 2018. Setting: The sample included pediatric intensive care physicians in North and South America, Asia, Europe, and Australia/New Zealand. Measurement: Questions consisted of: 1) characteristics of intensivists and hospital, 2) practice of high flow nasal cannula, 3) supportive treatment, and 4) research of high flow nasal cannula. Interventions: None. Main Results: We collected data from 1,031 respondents; 919 (North America, 215; Australia/New Zealand, 34; Asia, 203; South America, 186; Europe, 281) were analyzed. Sixty-nine percent of the respondents used high flow nasal cannula in non-PICU settings in their institutions. For a case of bronchiolitis/pneumonia infant, 2 L/kg/min of initial flow rate was the most commonly used. For a scenario of pneumonia with 30 kg weight, more than 60% of the respondents initiated flow based on patient body weight; while, 18% applied a fixed flow rate. Noninvasive ventilation was considered as a next step in more than 85% of respondents when the patient is failing with high flow nasal cannula. Significant practice variations were observed in clinical practice markers used, flow weaning strategy, and supportive practices. Views comparing high flow nasal cannula to continuous positive airway pressure also noticeably varied across the respondents. Conclusions: Significant practice variations including views of high flow nasal cannula compared to continuous positive airway pressure was found among pediatric intensive care physicians. To expedite establishment and standardization of high flow nasal cannula practice, research aimed at understanding the heterogeneity found in this study should be undertaken.

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.
