Leader title	Director

Pediatric Acute Lung Injury and Sepsis Investigator’s (PALISI) Network is a multicenter research consortium focused on pediatric critical care, with emphasis on acute respiratory distress syndrome, sepsis, and acute lung injury in children. The Network coordinates clinical trials, observational studies, and translational research across academic medical centers, collaborating with federal agencies, philanthropic foundations, and professional societies to improve outcomes in pediatric intensive care units. It serves as a hub linking investigators at institutions such as Children's Hospital of Philadelphia, Boston Children's Hospital, and Johns Hopkins Hospital with funders like the National Institutes of Health and agencies including the National Heart, Lung, and Blood Institute.

History

The Network traces origins to cooperative pediatric research movements in the late 20th century, influenced by multicenter trial models at Duke University Hospital, Massachusetts General Hospital, and University of California, San Francisco Medical Center. Early efforts paralleled initiatives from the National Institutes of Health and programmatic shifts after landmark events like the publication of adult ARDSNet trial results and pediatric sepsis campaigns promoted by American Academy of Pediatrics committees. Growth accelerated through partnerships with consortia patterned after networks at Vanderbilt University Medical Center, Cincinnati Children's Hospital Medical Center, and Seattle Children's Hospital, enabling large-scale observational studies and randomized controlled trials across North America and beyond.

Organization and Governance

Governance employs a steering committee model with representation from principal investigators at major centers such as Texas Children's Hospital, Stanford Health Care, and Children's Hospital Los Angeles. An executive committee interfaces with external stakeholders including the National Institute of Child Health and Human Development, the Centers for Disease Control and Prevention, and professional organizations like the Society of Critical Care Medicine and the Pediatric Critical Care Medicine editorial leadership. Subcommittees for biostatistics, data coordinating centers at institutions akin to RAND Corporation analytic units, and institutional review boards modeled on Johns Hopkins Institutional Review Board processes provide oversight. Membership policies reflect standards similar to those of Clinical and Translational Science Awards consortia and cooperative groups such as Children's Oncology Group.

Research Programs and Collaborations

Research spans clinical trials, cohort studies, and translational science in collaboration with partners like the National Heart, Lung, and Blood Institute, Eunice Kennedy Shriver National Institute of Child Health and Human Development, and international pediatric networks such as European Society of Paediatric and Neonatal Intensive Care. Programs include ventilator management protocols influenced by adult paradigms from ARDSNet, sepsis bundles aligned with Surviving Sepsis Campaign recommendations, and biomarker discovery drawing on platforms used by Human Genome Project researchers and consortia similar to Pediatric HIV/AIDS Cohort Study. Collaborations extend to academic partners at Yale School of Medicine, Columbia University Irving Medical Center, University of Toronto, and industry partners modeled after alliances with Pfizer and GlaxoSmithKline for device and therapeutic evaluation.

Key Clinical Trials and Findings

The Network has led multicenter randomized trials and observational registries that informed practice on pediatric mechanical ventilation, fluid management, and antimicrobial stewardship. Findings have influenced guidelines from organizations such as the American Thoracic Society, European Society of Cardiology (in cardiopulmonary overlap), and the American College of Chest Physicians. Trials paralleled methodological approaches used in studies at Cleveland Clinic and Mayo Clinic and produced outcomes cited alongside landmark pediatric trials from University of Michigan Health. Publications have been disseminated in journals associated with Johns Hopkins University Press, Oxford University Press, and editorial boards of The Lancet and New England Journal of Medicine-style venues.

Training, Education, and Career Development

The Network runs training initiatives that mirror career development programs at National Institutes of Health and academic fellowships at institutions like Harvard Medical School and University of Pennsylvania Perelman School of Medicine. Mentorship structures connect early-career investigators with senior faculty from centers such as University of California, Los Angeles, McGill University Health Centre, and Emory University School of Medicine. Educational outputs include workshops at conferences hosted by Society of Critical Care Medicine, symposia at American Academy of Pediatrics meetings, and curriculum modules similar to resources from Institute for Healthcare Improvement.

Funding and Partnerships

Support derives from federal grants from the National Institutes of Health and cooperative agreements with the National Heart, Lung, and Blood Institute, supplemented by foundation grants modeled on funding mechanisms used by the Robert Wood Johnson Foundation, Bill & Melinda Gates Foundation, and partnerships with device manufacturers akin to Medtronic and pharmaceutical companies like Novartis. Data management and trial coordination utilize infrastructures comparable to ClinicalTrials.gov registration processes and data standards developed by Food and Drug Administration collaborations.

Impact and Legacy on Pediatric Critical Care

The Network has shaped standards of care in pediatric intensive care units at centers such as Great Ormond Street Hospital, Royal Children's Hospital, Melbourne, and Hospital for Sick Children (Toronto), influencing ventilator strategies, sepsis recognition, and outcome measurement frameworks. Its legacy parallels contributions from cooperative groups like the Children's Oncology Group and informs policy and guideline development by bodies including the American Academy of Pediatrics and World Health Organization pediatric critical care initiatives. The Network's multicenter infrastructure continues to enable rapid responses to emergent threats to pediatric respiratory health, building on collaborative precedents established by academic medical centers and international research consortia.
