BNT162b2 mRNA Vaccination Against Coronavirus Disease 2019 is Associated With a Decreased Likelihood of Multisystem Inflammatory Syndrome in Children Aged 5-18 Years-United States, July 2021 - April 2022
(Oxford University Press, 2023) Zambrano, Laura D.; Newhams, Margaret M.; Olson, Samantha M.; Halasa, Natasha B.; Price, Ashley M.; Orzel, Amber O.; Young, Cameron C.; Boom, Julie A.; Sahni, Leila C.; Maddux, Aline B.; Bline, Katherine E.; Kamidani, Satoshi; Tarquinio, Keiko M.; Chiotos, Kathleen; Schuster, Jennifer E.; Cullimore, Melissa L.; Heidemann, Sabrina M.; Hobbs, Charlotte V.; Nofziger, Ryan A.; Pannaraj, Pia S.; Cameron, Melissa A.; Walker, Tracie C.; Schwartz, Stephanie P.; Michelson, Kelly N.; Coates, Bria M.; Flori, Heidi R.; Mack, Elizabeth H.; Smallcomb, Laura; Gertz, Shira J.; Bhumbra, Samina S.; Bradford, Tamara T.; Levy, Emily R.; Kong, Michele; Irby, Katherine; Cvijanovich, Natalie Z.; Zinter, Matt S.; Bowens, Cindy; Crandall, Hillary; Hume, Janet R.; Patel, Manish M.; Campbell, Angela P.; Randolph, Adrienne G.; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine
Background: Multisystem inflammatory syndrome in children (MIS-C), linked to antecedent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, is associated with considerable morbidity. Prevention of SARS-CoV-2 infection or coronavirus disease 2019 (COVID-19) by vaccination might also decrease MIS-C likelihood. Methods: In a multicenter, case-control, public health investigation of children ages 5-18 years hospitalized from 1 July 2021 to 7 April 2022, we compared the odds of being fully vaccinated (2 doses of BNT162b2 vaccine ≥28 days before hospital admission) between MIS-C case-patients and hospital-based controls who tested negative for SARS-CoV-2. These associations were examined by age group, timing of vaccination, and periods of Delta and Omicron variant predominance using multivariable logistic regression. Results: We compared 304 MIS-C case-patients (280 [92%] unvaccinated) with 502 controls (346 [69%] unvaccinated). MIS-C was associated with decreased likelihood of vaccination (adjusted OR [aOR]: .16; 95% CI: .10-.26), including among children ages 5-11 years (aOR: .22; 95% CI: .10-.52), ages 12-18 years (aOR: .10; 95% CI: .05-.19), and during the Delta (aOR: .06; 95% CI: .02-.15) and Omicron (aOR: .22; 95% CI: .11-.42) variant-predominant periods. This association persisted beyond 120 days after the second dose (aOR: .08; 95% CI: .03-.22) in 12-18-year-olds. Among all MIS-C case-patients, 187 (62%) required intensive care unit admission and 280 (92%) vaccine-eligible case-patients were unvaccinated. Conclusions: Vaccination with 2 doses of BNT162b2 is associated with reduced likelihood of MIS-C in children ages 5-18 years. Most vaccine-eligible hospitalized patients with MIS-C were unvaccinated.
BNT162b2 Protection against the Omicron Variant in Children and Adolescents
(Massachusetts Medical Society, 2022) Price, Ashley M.; Olson, Samantha M.; Newhams, Margaret M.; Halasa, Natasha B.; Boom, Julie A.; Sahni, Leila C.; Pannaraj, Pia S.; Irby, Katherine; Bline, Katherine E.; Maddux, Aline B.; Nofziger, Ryan A.; Cameron, Melissa A.; Walker, Tracie C.; Schwartz, Stephanie P.; Mack, Elizabeth H.; Smallcomb, Laura; Schuster, Jennifer E.; Hobbs, Charlotte V.; Kamidani, Satoshi; Tarquinio, Keiko M.; Bradford, Tamara T.; Levy, Emily R.; Chiotos, Kathleen; Bhumbra, Samina S.; Cvijanovich, Natalie Z.; Heidemann, Sabrina M.; Cullimore, Melissa L.; Gertz, Shira J.; Coates, Bria M.; Staat, Mary A.; Zinter, Matt S.; Kong, Michele; Chatani, Brandon M.; Hume, Janet R.; Typpo, Katri V.; Maamari, Mia; Flori, Heidi R.; Tenforde, Mark W.; Zambrano, Laura D.; Campbell, Angela P.; Patel, Manish M.; Randolph, Adrienne G.; Overcoming Covid-19 Investigators; Pediatrics, School of Medicine
Background: Spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) B.1.1.529 (omicron) variant, which led to increased U.S. hospitalizations for coronavirus disease 2019 (Covid-19), generated concern about immune evasion and the duration of protection from vaccines in children and adolescents. Methods: Using a case-control, test-negative design, we assessed vaccine effectiveness against laboratory-confirmed Covid-19 leading to hospitalization and against critical Covid-19 (i.e., leading to receipt of life support or to death). From July 1, 2021, to February 17, 2022, we enrolled case patients with Covid-19 and controls without Covid-19 at 31 hospitals in 23 states. We estimated vaccine effectiveness by comparing the odds of antecedent full vaccination (two doses of BNT162b2 messenger RNA vaccine) at least 14 days before illness among case patients and controls, according to time since vaccination for patients 12 to 18 years of age and in periods coinciding with circulation of B.1.617.2 (delta) (July 1, 2021, to December 18, 2021) and omicron (December 19, 2021, to February 17, 2022) among patients 5 to 11 and 12 to 18 years of age. Results: We enrolled 1185 case patients (1043 [88%] of whom were unvaccinated, 291 [25%] of whom received life support, and 14 of whom died) and 1627 controls. During the delta-predominant period, vaccine effectiveness against hospitalization for Covid-19 among adolescents 12 to 18 years of age was 93% (95% confidence interval [CI], 89 to 95) 2 to 22 weeks after vaccination and was 92% (95% CI, 80 to 97) at 23 to 44 weeks. Among adolescents 12 to 18 years of age (median interval since vaccination, 162 days) during the omicron-predominant period, vaccine effectiveness was 40% (95% CI, 9 to 60) against hospitalization for Covid-19, 79% (95% CI, 51 to 91) against critical Covid-19, and 20% (95% CI, -25 to 49) against noncritical Covid-19. During the omicron period, vaccine effectiveness against hospitalization among children 5 to 11 years of age was 68% (95% CI, 42 to 82; median interval since vaccination, 34 days). Conclusions: BNT162b2 vaccination reduced the risk of omicron-associated hospitalization by two thirds among children 5 to 11 years of age. Although two doses provided lower protection against omicron-associated hospitalization than against delta-associated hospitalization among adolescents 12 to 18 years of age, vaccination prevented critical illness caused by either variant.
Community-Onset Bacterial Coinfection in Children Critically Ill With Severe Acute Respiratory Syndrome Coronavirus 2 Infection
(Oxford University Press, 2023-03-06) Moffitt, Kristin L.; Nakamura, Mari M.; Young, Cameron C.; Newhams, Margaret M.; Halasa, Natasha B.; Reed, J. Nelson; Fitzgerald, Julie C.; Spinella, Philip C.; Soma, Vijaya L.; Walker, Tracie C.; Loftis, Laura L.; Maddux, Aline B.; Kong, Michele; Rowan, Courtney M.; Hobbs, Charlotte V.; Schuster, Jennifer E.; Riggs, Becky J.; McLaughlin, Gwenn E.; Michelson, Kelly N.; Hall, Mark W.; Babbitt, Christopher J.; Cvijanovich, Natalie Z.; Zinter, Matt S.; Maamari, Mia; Schwarz, Adam J.; Singh, Aalok R.; Flori, Heidi R.; Gertz, Shira J.; Staat, Mary A.; Giuliano, John S., Jr.; Hymes, Saul R.; Clouser, Katharine N.; McGuire, John; Carroll, Christopher L.; Thomas, Neal J.; Levy, Emily R.; Randolph, Adrienne G.; Pediatrics, School of Medicine
Background: Community-onset bacterial coinfection in adults hospitalized with coronavirus disease 2019 (COVID-19) is reportedly uncommon, though empiric antibiotic use has been high. However, data regarding empiric antibiotic use and bacterial coinfection in children with critical illness from COVID-19 are scarce. Methods: We evaluated children and adolescents aged <19 years admitted to a pediatric intensive care or high-acuity unit for COVID-19 between March and December 2020. Based on qualifying microbiology results from the first 3 days of admission, we adjudicated whether patients had community-onset bacterial coinfection. We compared demographic and clinical characteristics of those who did and did not (1) receive antibiotics and (2) have bacterial coinfection early in admission. Using Poisson regression models, we assessed factors associated with these outcomes. Results: Of the 532 patients, 63.3% received empiric antibiotics, but only 7.1% had bacterial coinfection, and only 3.0% had respiratory bacterial coinfection. In multivariable analyses, empiric antibiotics were more likely to be prescribed for immunocompromised patients (adjusted relative risk [aRR], 1.34 [95% confidence interval {CI}, 1.01-1.79]), those requiring any respiratory support except mechanical ventilation (aRR, 1.41 [95% CI, 1.05-1.90]), or those requiring invasive mechanical ventilation (aRR, 1.83 [95% CI, 1.36-2.47]) (compared with no respiratory support). The presence of a pulmonary comorbidity other than asthma (aRR, 2.31 [95% CI, 1.15-4.62]) was associated with bacterial coinfection. Conclusions: Community-onset bacterial coinfection in children with critical COVID-19 is infrequent, but empiric antibiotics are commonly prescribed. These findings inform antimicrobial use and support rapid de-escalation when evaluation shows coinfection is unlikely.
Cross-reactive immunity against the SARS-CoV-2 Omicron variant is low in pediatric patients with prior COVID-19 or MIS-C
(Springer Nature, 2022-05-27) Tang, Juanjie; Novak, Tanya; Hecker, Julian; Grubbs, Gabrielle; Tuz Zahra, Fatema; Bellusci, Lorenza; Pourhashemi, Sara; Chou, Janet; Moffitt, Kristin; Halasa, Natasha B.; Schwartz, Stephanie P.; Walker, Tracie C.; Tarquinio, Keiko M.; Zinter, Matt S.; Staat, Mary A.; Gertz, Shira J.; Cvijanovich, Natalie Z.; Schuster, Jennifer E.; Loftis, Laura L.; Coates, Bria M.; Mack, Elizabeth H.; Irby, Katherine; Fitzgerald, Julie C.; Rowan, Courtney M.; Kong, Michele; Flori, Heidi R.; Maddux, Aline B.; Shein, Steven L.; Crandall, Hillary; Hume, Janet R.; Hobbs, Charlotte V.; Tremoulet, Adriana H.; Shimizu, Chisato; Burns, Jane C.; Chen, Sabrina R.; Moon, Hye Kyung; Lange, Christoph; Randolph, Adrienne G.; Khurana, Surender; Pediatrics, School of Medicine
Neutralization capacity of antibodies against Omicron after a prior SARS-CoV-2 infection in children and adolescents is not well studied. Therefore, we evaluated virus-neutralizing capacity against SARS-CoV-2 Alpha, Beta, Gamma, Delta and Omicron variants by age-stratified analyses (<5, 5-11, 12-21 years) in 177 pediatric patients hospitalized with severe acute COVID-19, acute MIS-C, and in convalescent samples of outpatients with mild COVID-19 during 2020 and early 2021. Across all patients, less than 10% show neutralizing antibody titers against Omicron. Children <5 years of age hospitalized with severe acute COVID-19 have lower neutralizing antibodies to SARS-CoV-2 variants compared with patients >5 years of age. As expected, convalescent pediatric COVID-19 and MIS-C cohorts demonstrate higher neutralization titers than hospitalized acute COVID-19 patients. Overall, children and adolescents show some loss of cross-neutralization against all variants, with the most pronounced loss against Omicron. In contrast to SARS-CoV-2 infection, children vaccinated twice demonstrated higher titers against Alpha, Beta, Gamma, Delta and Omicron. These findings can influence transmission, re-infection and the clinical disease outcome from emerging SARS-CoV-2 variants and supports the need for vaccination in children.
A Description of COVID-19-Directed Therapy in Children Admitted to US Intensive Care Units 2020
(Oxford University Press, 2022) Schuster, Jennifer E.; Halasa, Natasha B.; Nakamura, Mari; Levy, Emily R.; Fitzgerald, Julie C.; Young, Cameron C.; Newhams, Margaret M.; Bourgeois, Florence; Staat, Mary A.; Hobbs, Charlotte V.; Dapul, Heda; Feldstein, Leora R.; Jackson, Ashley M.; Mack, Elizabeth H.; Walker, Tracie C.; Maddux, Aline B.; Spinella, Philip C.; Loftis, Laura L.; Kong, Michele; Rowan, Courtney M.; Bembea, Melania M.; McLaughlin, Gwenn E.; Hall, Mark W.; Babbitt, Christopher J.; Maamari, Mia; Zinter, Matt S.; Cvijanovich, Natalie Z.; Michelson, Kelly N.; Gertz, Shira J.; Carroll, Christopher L.; Thomas, Neal J.; Giuliano, John S., Jr.; Singh, Aalok R.; Hymes, Saul R.; Schwarz, Adam J.; McGuire, John K.; Nofziger, Ryan A.; Flori, Heidi R.; Clouser, Katharine N.; Wellnitz, Kari; Cullimore, Melissa L.; Hume, Janet R.; Patel, Manish; Randolph, Adrienne G.; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine
Background: It is unclear how acute coronavirus disease 2019 (COVID-19)-directed therapies are used in children with life-threatening COVID-19 in US hospitals. We described characteristics of children hospitalized in the intensive care unit or step-down unit (ICU/SDU) who received COVID-19-directed therapies and the specific therapies administered. Methods: Between March 15, 2020 and December 27, 2020, children <18 years of age in the ICU/SDU with acute COVID-19 at 48 pediatric hospitals in the United States were identified. Demographics, laboratory values, and clinical course were compared in children who did and did not receive COVID-19-directed therapies. Trends in COVID-19-directed therapies over time were evaluated. Results: Of 424 children in the ICU/SDU, 235 (55%) received COVID-19-directed therapies. Children who received COVID-19-directed therapies were older than those who did not receive COVID-19-directed therapies (13.3 [5.6-16.2] vs 9.8 [0.65-15.9] years), more had underlying medical conditions (188 [80%] vs 104 [55%]; difference = 25% [95% CI: 16% to 34%]), more received respiratory support (206 [88%] vs 71 [38%]; difference = 50% [95% CI: 34% to 56%]), and more died (8 [3.4%] vs 0). Of the 235 children receiving COVID-19-directed therapies, 172 (73%) received systemic steroids and 150 (64%) received remdesivir, with rising remdesivir use over the study period (14% in March/April to 57% November/December). Conclusion: Despite the lack of pediatric data evaluating treatments for COVID-19 in critically ill children, more than half of children requiring intensive or high acuity care received COVID-19-directed therapies.
Early Use of Adjunctive Therapies for Pediatric Acute Respiratory Distress Syndrome: A PARDIE Study
(American Thoracic Society, 2020-06) Rowan, Courtney M.; Klein, Margaret J.; Hsing, Deyin Doreen; Dahmer, Mary K.; Spinella, Philip C.; Emeriaud, Guillaume; Hassinger, Amanda B.; Piñeres-Olave, Byron E.; Flori, Heidi R.; Haileselassie, Bereketeab; Lopez-Fernandez, Yolanda M.; Chima, Ranjit S.; Shein, Steven L.; Maddux, Aline B.; Lillie, Jon; Izquierdo, Ledys; Kneyber, Martin C.J.; Smith, Lincoln S.; Khemani, Robinder G.; Thomas, Neal J.; Yehya, Nadir; Pediatrics, School of Medicine
Rationale: Few data exist to guide early adjunctive therapy use in pediatric acute respiratory distress syndrome (PARDS).Objectives: To describe contemporary use of adjunctive therapies for early PARDS as a framework for future investigations.Methods: This was a preplanned substudy of a prospective, international, cross-sectional observational study of children with PARDS from 100 centers over 10 study weeks.Measurements and Main Results: We investigated six adjunctive therapies for PARDS: continuous neuromuscular blockade, corticosteroids, inhaled nitric oxide (iNO), prone positioning, high-frequency oscillatory ventilation (HFOV), and extracorporeal membrane oxygenation. Almost half (45%) of children with PARDS received at least one therapy. Variability was noted in the median starting oxygenation index of each therapy; corticosteroids started at the lowest oxygenation index (13.0; interquartile range, 7.6-22.0) and HFOV at the highest (25.7; interquartile range, 16.7-37.3). Continuous neuromuscular blockade was the most common, used in 31%, followed by iNO (13%), corticosteroids (10%), prone positioning (10%), HFOV (9%), and extracorporeal membrane oxygenation (3%). Steroids, iNO, and HFOV were associated with comorbidities. Prone positioning and HFOV were more common in middle-income countries and less frequently used in North America. The use of multiple ancillary therapies increased over the first 3 days of PARDS, but there was not an easily identifiable pattern of combination or order of use.Conclusions: The contemporary description of prevalence, combinations of therapies, and oxygenation threshold for which the therapies are applied is important for design of future studies. Region of the world, income, and comorbidities influence adjunctive therapy use and are important variables to include in PARDS investigations.

(Massachusetts Medical Society, 2022) Olson, Samantha M.; Newhams, Margaret M.; Halasa, Natasha B.; Price, Ashley M.; Boom, Julie A.; Sahni, Leila C.; Pannaraj, Pia S.; Irby, Katherine; Walker, Tracie C.; Schwartz, Stephanie P.; Maddux, Aline B.; Mack, Elizabeth H.; Bradford, Tamara T.; Schuster, Jennifer E.; Nofziger, Ryan A.; Cameron, Melissa A.; Chiotos, Kathleen; Cullimore, Melissa L.; Gertz, Shira J.; Levy, Emily R.; Kong, Michele; Cvijanovich, Natalie Z.; Staat, Mary A.; Kamidani, Satoshi; Chatani, Brandon M.; Bhumbra, Samina S.; Bline, Katherine E.; Gaspers, Mary G.; Hobbs, Charlotte V.; Heidemann, Sabrina M.; Maamari, Mia; Flori, Heidi R.; Hume, Janet R.; Zinter, Matt S.; Michelson, Kelly N.; Zambrano, Laura D.; Campbell, Angela P.; Patel, Manish M.; Randolph, Adrienne G.; Pediatrics, School of Medicine
Background: The increasing incidence of pediatric hospitalizations associated with coronavirus disease 2019 (Covid-19) caused by the B.1.617.2 (delta) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the United States has offered an opportunity to assess the real-world effectiveness of the BNT162b2 messenger RNA vaccine in adolescents between 12 and 18 years of age. Methods: We used a case-control, test-negative design to assess vaccine effectiveness against Covid-19 resulting in hospitalization, admission to an intensive care unit (ICU), the use of life-supporting interventions (mechanical ventilation, vasopressors, and extracorporeal membrane oxygenation), or death. Between July 1 and October 25, 2021, we screened admission logs for eligible case patients with laboratory-confirmed Covid-19 at 31 hospitals in 23 states. We estimated vaccine effectiveness by comparing the odds of antecedent full vaccination (two doses of BNT162b2) in case patients as compared with two hospital-based control groups: patients who had Covid-19-like symptoms but negative results on testing for SARS-CoV-2 (test-negative) and patients who did not have Covid-19-like symptoms (syndrome-negative). Results: A total of 445 case patients and 777 controls were enrolled. Overall, 17 case patients (4%) and 282 controls (36%) had been fully vaccinated. Of the case patients, 180 (40%) were admitted to the ICU, and 127 (29%) required life support; only 2 patients in the ICU had been fully vaccinated. The overall effectiveness of the BNT162b2 vaccine against hospitalization for Covid-19 was 94% (95% confidence interval [CI], 90 to 96); the effectiveness was 95% (95% CI, 91 to 97) among test-negative controls and 94% (95% CI, 89 to 96) among syndrome-negative controls. The effectiveness was 98% against ICU admission and 98% against Covid-19 resulting in the receipt of life support. All 7 deaths occurred in patients who were unvaccinated. Conclusions: Among hospitalized adolescent patients, two doses of the BNT162b2 vaccine were highly effective against Covid-19-related hospitalization and ICU admission or the receipt of life support.

Effectiveness of Maternal Vaccination with mRNA COVID-19 Vaccine During Pregnancy Against COVID-19–Associated Hospitalization in Infants Aged <6 Months — 17 States, July 2021–January 2022
(Center for Disease Control, 2022-02-18) Halasa, Natasha B.; Olson, Samantha M.; Staat, Mary A.; Newhams, Margaret M.; Price, Ashley M.; Boom, Julie A.; Sahni, Leila C.; Cameron, Melissa A.; Pannaraj, Pia S.; Bline, Katherine E.; Bhumbra, Samina S.; Bradford, Tamara T.; Chiotos, Kathleen; Coates, Bria M.; Cullimore, Melissa L.; Cvijanovich, Natalie Z.; Flori, Heidi R.; Gertz, Shira J.; Heidemann, Sabrina M.; Hobbs, Charlotte V.; Hume, Janet R.; Irby, Katherine; Kamidani, Satoshi; Kong, Michele; Levy, Emily R.; Mack, Elizabeth H.; Maddux, Aline B.; Michelson, Kelly N.; Nofziger, Ryan A.; Schuster, Jennifer E.; Schwartz, Stephanie P.; Smallcomb, Laura; Tarquinio, Keiko M.; Walker, Tracie C.; Zinter, Matt S.; Gilboa, Suzanne M.; Polen, Kara N.; Campbell, Angela P.; Randolph, Adrienne G.; Patel, Manish M.; Overcoming COVID-19 Investigators; Overcoming COVID-19 Network; Pediatrics, School of Medicine
COVID-19 vaccination is recommended for persons who are pregnant, breastfeeding, trying to get pregnant now, or who might become pregnant in the future, to protect them from COVID-19.§ Infants are at risk for life-threatening complications from COVID-19, including acute respiratory failure (1). Evidence from other vaccine-preventable diseases suggests that maternal immunization can provide protection to infants, especially during the high-risk first 6 months of life, through passive transplacental antibody transfer (2). Recent studies of COVID-19 vaccination during pregnancy suggest the possibility of transplacental transfer of SARS-CoV-2-specific antibodies that might provide protection to infants (3-5); however, no epidemiologic evidence currently exists for the protective benefits of maternal immunization during pregnancy against COVID-19 in infants. The Overcoming COVID-19 network conducted a test-negative, case-control study at 20 pediatric hospitals in 17 states during July 1, 2021-January 17, 2022, to assess effectiveness of maternal completion of a 2-dose primary mRNA COVID-19 vaccination series during pregnancy against COVID-19 hospitalization in infants. Among 379 hospitalized infants aged <6 months (176 with COVID-19 [case-infants] and 203 without COVID-19 [control-infants]), the median age was 2 months, 21% had at least one underlying medical condition, and 22% of case- and control-infants were born premature (<37 weeks gestation). Effectiveness of maternal vaccination during pregnancy against COVID-19 hospitalization in infants aged <6 months was 61% (95% CI = 31%-78%). Completion of a 2-dose mRNA COVID-19 vaccination series during pregnancy might help prevent COVID-19 hospitalization among infants aged <6 months.
Executive Summary of the Second International Guidelines for the Diagnosis and Management of Pediatric Acute Respiratory Distress Syndrome (PALICC-2)

Scott; Yehya, Nadir; Zimmerman, Jerry J.; Khemani, Robinder G.; Pediatrics, School of Medicine
Objectives: We sought to update our 2015 work in the Second Pediatric Acute Lung Injury Consensus Conference (PALICC-2) guidelines for the diagnosis and management of pediatric acute respiratory distress syndrome (PARDS), considering new evidence and topic areas that were not previously addressed. Design: International consensus conference series involving 52 multidisciplinary international content experts in PARDS and four methodology experts from 15 countries, using consensus conference methodology, and implementation science. Setting: Not applicable. Patients: Patients with or at risk for PARDS. Interventions: None. Measurements and main results: Eleven subgroups conducted systematic or scoping reviews addressing 11 topic areas: 1) definition, incidence, and epidemiology; 2) pathobiology, severity, and risk stratification; 3) ventilatory support; 4) pulmonary-specific ancillary treatment; 5) nonpulmonary treatment; 6) monitoring; 7) noninvasive respiratory support; 8) extracorporeal support; 9) morbidity and long-term outcomes; 10) clinical informatics and data science; and 11) resource-limited settings. The search included MEDLINE, EMBASE, and CINAHL Complete (EBSCOhost) and was updated in March 2022. Grading of Recommendations, Assessment, Development, and Evaluation methodology was used to summarize evidence and develop the recommendations, which were discussed and voted on by all PALICC-2 experts. There were 146 recommendations and statements, including: 34 recommendations for clinical practice; 112 consensus-based statements with 18 on PARDS definition, 55 on good practice, seven on policy, and 32 on research. All recommendations and statements had agreement greater than 80%. Conclusions: PALICC-2 recommendations and consensus-based statements should facilitate the implementation and adherence to the best clinical practice in patients with PARDS. These results will also inform the development of future programs of research that are crucially needed to provide stronger evidence to guide the pediatric critical care teams managing these patients.
