Applicability of 2009 international consensus terminology and criteria for immune thrombocytopenia to a clinical pediatric population.

ABSTRACT: Since pediatric immune thrombocytopenia (ITP) is relatively infrequent, comparisons among clinical studies are critical but have previously been limited by differences in terminology. In 2009, an international working group (IWG) developed consensus criteria to enhance comparability in future studies in adults and children.We performed a retrospective medical record review of all pediatric ITP patients seen at a single children's hospital with a first visit between 2003 and 2010 and applied both historical (criteria(Hist) ) and IWG (criteria(IWG) ) ITP criteria to available clinical data.Among the 505 patients seen for ITP over 7 years, 98% could be classified as "acute" or "chronic" ITP using the criteria(Hist) , while only 90.7% could be classified as "newly diagnosed," "persistent," or "chronic" ITP using the criteria(IWG) (P?

Project description:ObjectivesTo assess the incidence, severity, and outcomes of pediatric acute respiratory distress syndrome following trauma using Pediatric Acute Lung Injury Consensus Conference criteria.DesignRetrospective cohort study.SettingLevel 1 pediatric trauma center.PatientsTrauma patients less than or equal to 17 years admitted to the ICU from 2009 to 2017.InterventionsNone.Measurements and main resultsWe queried electronic health records to identify patients meeting pediatric acute respiratory distress syndrome oxygenation criteria for greater than or equal to 6 hours and determined whether patients met complete pediatric acute respiratory distress syndrome criteria via chart review. We estimated associations between pediatric acute respiratory distress syndrome and outcome using generalized linear Poisson regression adjusted for age, injury mechanism, Injury Severity Score, and serious brain and chest injuries. Of 2,470 critically injured children, 103 (4.2%) met pediatric acute respiratory distress syndrome criteria. Mortality was 34.0% among pediatric acute respiratory distress syndrome patients versus 1.7% among patients without pediatric acute respiratory distress syndrome (adjusted relative risk, 3.7; 95% CI, 2.0-6.9). Mortality was 50.0% for severe pediatric acute respiratory distress syndrome at onset, 33.3% for moderate, and 30.5% for mild. Cause of death was neurologic in 60.0% and multiple organ failure in 34.3% of pediatric acute respiratory distress syndrome nonsurvivors versus neurologic in 85.4% of nonsurvivors without pediatric acute respiratory distress syndrome (p = 0.001). Among survivors, 77.1% of pediatric acute respiratory distress syndrome patients had functional disability at discharge versus 30.7% of patients without pediatric acute respiratory distress syndrome patients (p < 0.001), and only 17.5% of pediatric acute respiratory distress syndrome patients discharged home without ongoing care versus 86.4% of patients without pediatric acute respiratory distress syndrome (adjusted relative risk, 1.5; 1.1-2.1).ConclusionsIncidence and mortality associated with pediatric acute respiratory distress syndrome following traumatic injury are substantially higher than previously recognized, and pediatric acute respiratory distress syndrome development is associated with high risk of poor outcome even after adjustment for underlying injury type and severity.
