Scott; Yehya, Nadir; Zimmerman, Jerry J.; Khemani, Robinder G.; Pediatrics, School of MedicineObjectives: 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.Item High-Frequency Oscillatory Ventilation Use and Severe Pediatric ARDS in the Pediatric Hematopoietic Cell Transplant Recipient(Daedalus Enterprises, 2018-04) Rowan, Courtney M.; Loomis, Ashley; McArthur, Jennifer; Smith, Lincoln S.; Gertz, Shira J.; Fitzgerald, Julie C.; Nitu, Mara E.; Moser, Elizabeth A.S.; Hsing, Deyin D.; Duncan, Christine N.; Mahadeo, Kris M.; Moffet, Jerelyn; Hall, Mark W.; Pinos, Emily L.; Tamburro, Robert F.; Cheifetz, Ira M.; Investigators of the Pediatric Acute Lung Injury and Sepsis Network; Pediatrics, School of MedicineINTRODUCTION: The effectiveness of high-frequency oscillatory ventilation (HFOV) in the pediatric hematopoietic cell transplant patient has not been established. We sought to identify current practice patterns of HFOV, investigate parameters during HFOV and their association with mortality, and compare the use of HFOV to conventional mechanical ventilation in severe pediatric ARDS. METHODS: This is a retrospective analysis of a multi-center database of pediatric and young adult allogeneic hematopoietic cell transplant subjects requiring invasive mechanical ventilation for critical illness from 2009 through 2014. Twelve United States pediatric centers contributed data. Continuous variables were compared using a Wilcoxon rank-sum test or a Kruskal-Wallis analysis. For categorical variables, univariate analysis with logistic regression was performed. RESULTS: The database contains 222 patients, of which 85 subjects were managed with HFOV. Of this HFOV cohort, the overall pediatric ICU survival was 23.5% (n = 20). HFOV survivors were transitioned to HFOV at a lower oxygenation index than nonsurvivors (25.6, interquartile range 21.1-36.8, vs 37.2, interquartile range 26.5-52.2, P = .046). Survivors were transitioned to HFOV earlier in the course of mechanical ventilation, (day 0 vs day 2, P = .002). No subject survived who was transitioned to HFOV after 1 week of invasive mechanical ventilation. We compared subjects with severe pediatric ARDS treated only with conventional mechanical ventilation versus early HFOV (within 2 d of invasive mechanical ventilation) versus late HFOV. There was a trend toward difference in survival (conventional mechanical ventilation 24%, early HFOV 30%, and late HFOV 9%, P = .08). CONCLUSIONS: In this large database of pediatric allogeneic hematopoietic cell transplant subjects who had acute respiratory failure requiring invasive mechanical ventilation for critical illness with severe pediatric ARDS, early use of HFOV was associated with improved survival compared to late implementation of HFOV, and the subjects had outcomes similar to those treated only with conventional mechanical ventilation.Item Pediatric Organ Dysfunction Information Update Mandate (PODIUM) Contemporary Organ Dysfunction Criteria: Executive Summary(American Academy of Pediatrics, 2022) Bembea, Melania M.; Agus, Michael; Akcan-Arikan, Ayse; Alexander, Peta; Basu, Rajit; Bennett, Tellen D.; Bohn, Desmond; Brandão, Leonardo R.; Brown, Ann-Marie; Carcillo, Joseph A.; Checchia, Paul; Cholette, Jill; Cheifetz, Ira M.; Cornell, Timothy; Doctor, Allan; Eckerle, Michelle; Erickson, Simon; Farris, Reid W.D.; Faustino, E. Vincent S.; Fitzgerald, Julie C.; Fuhrman, Dana Y.; Giuliano, John S.; Guilliams, Kristin; Gaies, Michael; Gorga, Stephen M.; Hall, Mark; Hanson, Sheila J.; Hartman, Mary; Hassinger, Amanda B.; Irving, Sharon Y.; Jeffries, Howard; Jouvet, Philippe; Kannan, Sujatha; Karam, Oliver; Khemani, Robinder G.; Kissoon, Niranjan; Lacroix, Jacques; Laussen, Peter; Leclerc, Francis; Lee, Jan Hau; Leteurtre, Stephane; Lobner, Katie; McKiernan, Patrick J.; Menon, Kusum; Monagle, Paul; Muszynski, Jennifer A.; Odetola, Folafoluwa; Parker, Robert; Pathan, Nazima; Pierce, Richard W.; Pineda, Jose; Prince, Jose M.; Robinson, Karen A.; Rowan, Courtney M.; Ryerson, Lindsay M.; Sanchez-Pinto, L. Nelson; Schlapbach, Luregn J.; Selewski, David T.; Shekerdemian, Lara S.; Simon, Dennis; Smith, Lincoln S.; Squires, James E.; Squires, Robert H.; Sutherland, Scott M.; Ouellette, Yves; Spaeder, Michael C.; Srinivasan, Vijay; Steiner, Marie E.; Tasker, Robert C.; Thiagarajan, Ravi; Thomas, Neal; Tissieres, Pierre; Traube, Chani; Tucci, Marisa; Typpo, Katri V.; Wainwright, Mark S.; Ward, Shan L.; Watson, R. Scott; Weiss, Scott; Whitney, Jane; Willson, Doug; Wynn, James L.; Yehya, Nadir; Zimmerman, Jerry J.; Pediatrics, School of MedicinePrior criteria for organ dysfunction in critically ill children were based mainly on expert opinion. We convened the Pediatric Organ Dysfunction Information Update Mandate (PODIUM) expert panel to summarize data characterizing single and multiple organ dysfunction and to derive contemporary criteria for pediatric organ dysfunction. The panel was composed of 88 members representing 47 institutions and 7 countries. We conducted systematic reviews of the literature to derive evidence-based criteria for single organ dysfunction for neurologic, cardiovascular, respiratory, gastrointestinal, acute liver, renal, hematologic, coagulation, endocrine, endothelial, and immune system dysfunction. We searched PubMed and Embase from January 1992 to January 2020. Study identification was accomplished using a combination of medical subject headings terms and keywords related to concepts of pediatric organ dysfunction. Electronic searches were performed by medical librarians. Studies were eligible for inclusion if the authors reported original data collected in critically ill children; evaluated performance characteristics of scoring tools or clinical assessments for organ dysfunction; and assessed a patient-centered, clinically meaningful outcome. Data were abstracted from each included study into an electronic data extraction form. Risk of bias was assessed using the Quality in Prognosis Studies tool. Consensus was achieved for a final set of 43 criteria for pediatric organ dysfunction through iterative voting and discussion. Although the PODIUM criteria for organ dysfunction were limited by available evidence and will require validation, they provide a contemporary foundation for researchers to identify and study single and multiple organ dysfunction in critically ill children.Item Respiratory pathogens associated with intubated pediatric patients following hematopoietic cell transplant(Wiley, 2020-08) Gertz, Shira J.; McArthur, Jennifer; Hsing, Deyin D.; Nitu, Mara E.; Smith, Lincoln S.; Loomis, Ashley; Fitzgerald, Julie C.; Duncan, Christine N.; Mahadeo, Kris M.; Moffet, Jerelyn; Hall, Mark W.; Pinos, Emily L.; Cheifetz, Ira M.; Rowan, Courtney M.; Pediatric Acute Lung Injury and Sepsis Investigators (PALISI) Network; Pediatrics, School of MedicineBackground We describe organisms found in the respiratory tracts of a multicenter cohort of pediatric hematopoietic cell transplant (HCT) recipients with respiratory failure. Methods Twelve centers contributed up to 25 pediatric allogeneic HCT recipients requiring mechanical ventilation for respiratory failure to a retrospective database. Positive respiratory pathogens and method of obtaining sample were recorded. Outcomes were assessed using Mann-Whitney U test or chi-squared analysis. Results Of the 222 patients in the database, ages 1 month through 21 years, 34.6% had a positive respiratory culture. 105 pathogens were identified in 77 patients; of those, 48.6% were viral, 34.3% bacterial, 16.2% fungal, and 1% parasitic. PICU mortality with a respiratory pathogen was 68.8% compared to 54.9% for those without a respiratory pathogen (P = .045). Those with a positive respiratory pathogen had longer PICU length of stay, 20 days (IQR 14.0, 36.8) vs 15 (IQR 6.5, 32.0), P = .002, and a longer course of mechanical ventilation, 17 days (IQR 10, 29.5) vs 8 (3, 17), P < .0001. Method of pathogen identification, type of pathogen, and the presence of multiple pathogens were not associated with changes in PICU outcomes. Conclusions In this multicenter retrospective cohort of intubated pediatric post-HCT patients, there was high variability in the respiratory pathogens identified. Type of pathogen and method of detection did not affect PICU mortality. The presence of any organism leads to increased PICU mortality, longer PICU stay, and increased duration of mechanical ventilation suggesting that early detection and treatment of pathogens may be beneficial in this population.Item Tracheostomy and Long-Term Mechanical Ventilation in Children after Veno-Venous Extracorporeal Membrane Oxygenation(Wiley, 2021-09) Mallory, Palen P.; Barbaro, Ryan P.; Bembea, Melania M.; Bridges, Brian C.; Chima, Ranjit S.; Kilbaugh, Todd J.; Potera, Renee M.; Rosner, Elizabeth A.; Sandhu, Hitesh S.; Slaven, James E.; Tarquinio, Keiko M.; Cheifetz, Ira M.; Friedman, Matthew L.; Biostatistics, School of Public HealthObjective Our objective is to characterize the incidence of tracheostomy placement and of new requirement for long-term mechanical ventilation after extracorporeal membrane oxygenation (ECMO) among children with acute respiratory failure. We examine whether an association exists between demographics, pre-ECMO and ECMO clinical factors, and the placement of a tracheostomy or need for long-term mechanical ventilation. Methods A retrospective multicenter cohort study was conducted at 10 quaternary care pediatric academic centers, including children supported with veno-venous (V-V) ECMO from 2011 to 2016. Results Among 202 patients, 136 (67%) survived to ICU discharge. All tracheostomies were placed after ECMO decannulation, in 22 patients, with 19 of those surviving to ICU discharge (14% of survivors). Twelve patients (9% of survivors) were discharged on long-term mechanical ventilation. Tracheostomy placement and discharge on home ventilation were not associated with pre-ECMO severity of illness or pre-existing chronic illness. Patients who received a tracheostomy were older and weighed more than patients who did not receive a tracheostomy, although this association did not exist among patients discharged on home ventilation. ECMO duration was longer in those who received a tracheostomy compared to those who did not, as well as for those discharged on home ventilation, compared to those who were not. Conclusion The 14% rate for tracheostomy placement and 9% rate for discharge on long-term mechanical ventilation after V-V ECMO are important patient centered findings. This work informs anticipatory guidance provided to families of patients requiring prolonged respiratory ECMO support, and lays the foundation for future research.

We compared the outcomes of children with oncological diagnoses or HCT supported with V-V ECMO to other children who have received V-V ECMO support. In this cohort of 204 patients supported with V-V ECMO, 30 (15%) had a diagnosis of cancer or a history of HCT. There were 21 patients who had oncological diagnoses without HCT and 9 children were post-HCT. The oncology/HCT group had a higher overall ICU mortality (67% vs. 28%, p<0.001), mortality on ECMO (43% vs 21%, p<0.01), and ICU mortality among ECMO survivors (35% vs 8%, p<0.01). The oncology/HCT group had a higher rate of conversion to veno-arterial (V-A) ECMO (23% vs. 9%, p=0.02) (RR 2.5, 95% CI 1.1–5.6). Children with cancer or HCT were older (6.6 years vs 2.9 years, p=0.02) and had higher creatinine levels (0.65 mg/dL vs 0.4 mg/dL, p=0.04) but were similar to the rest of the cohort for other pre-ECMO variables. For post-HCT patients, survival was significantly worse for those whose indication for HCT was cancer or immunodeficiency (0/6) as compared to other nonmalignant indications (3/3) (p=0.01).
