Abstract
AIM
Pre-arrest morbidity in adults who suffer out-of-hospital cardiac arrest (OHCA) is associated with increased mortality and poorer neurologic outcomes. The objective of this study was to determine if a similar association is seen in pediatric patients.
METHODS
We performed a secondary analysis of data from the Therapeutic Hypothermia after Pediatric Cardiac Arrest Out-of-Hospital trial. Study sites included 36 pediatric intensive care units across the United States and Canada. The study enrolled children between the ages of 48 hours and 18 years following an OHCA between September 1, 2009 and December 31, 2012. For our analysis, patients with (N = 151) and without (N = 142) pre-arrest comorbidities were evaluated to assess morbidity, survival, and neurologic function following OHCA.
RESULTS
No significant difference in 28-day survival was seen between groups. Dependence on technology and neurobehavioral outcomes were assessed among survivors using the Vineland Adaptive Behavior Scales-Second Edition (VABS-II), Pediatric Cerebral Performance Category (PCPC) and Pediatric Overall Performance Category (POPC). Children with pre-existing comorbidities maintained worse neurobehavioral function at twelve months, evidenced by poorer scores on POPC (p = 0.016), PCPC (p = 0.044), and VABS-II (p = 0.020). They were more likely to have a tracheostomy at hospital discharge (p = 0.034), require supplemental oxygen at three months (p = 0.039) and twelve months (p = 0.034), and be mechanically ventilated at twelve months (p = 0.041).
CONCLUSIONS
There was no difference in survival to 28 days following OHCA in children with pre-existing comorbidity compared to previously healthy children. The group with pre-existing comorbidity was more reliant on technology following arrest and exhibited worse neurobehavioral outcomes.
