BackgroundManagement decisions and parental counseling after pediatric cardiac arrest depend on the ability of physicians to make accurate and timely predictions regarding neurological recovery. We evaluated neurologists and intensivists performing neuroprognostication after cardiac arrest to determine prediction agreement, accuracy, and confidence.MethodsPediatric neurologists (n = 10) and intensivists (n = 9) reviewed 18 cases of children successfully resuscitated from a cardiac arrest and managed in the pediatric intensive care unit. Cases were sequentially presented (after arrest day 1, days 2-4, and days 5-7), with updated examinations, neurophysiologic data, and neuroimaging data. At each time period, physicians predicted outcome by Pediatric Cerebral Performance Category and specified prediction confidence.ResultsPredicted discharge Pediatric Cerebral Performance Category versus actual hospital discharge Pediatric Cerebral Performance Category outcomes were compared. Exact (Predicted Pediatric Cerebral Performance Category - Actual Pediatric Cerebral Performance Category = 0) and close (Predicted Pediatric Cerebral Performance Category - Actual Pediatric Cerebral Performance Category = ±1) outcome prediction accuracies for all physicians improved over successive periods (P < 0.05). Prediction accuracy did not differ significantly between physician groups at any period or overall. Agreement improved over time among neurologists (day 1 Kappa [κ], 0.28; days 2-4 κ, 0.43; days 5-7 κ, 0.68) and among intensivists (day 1 κ, 0.30; days 2-4 κ, 0.44; days 5-7 κ, 0.57). Prediction confidence increased over time (P < 0.001) and did not differ between physician groups.ConclusionsInter-rater agreement among neurologists and among intensivists improved over time and reached moderate levels. For all physicians, prediction accuracy and confidence improved over time. Further prospective research is needed to better characterize how physicians objectively and subjectively estimate neurological recovery after acute brain injury.Copyright © 2014 Elsevier Inc.
