Neurobehavioral Outcomes in Children After Out-of-Hospital Cardiac Arrest.

ABSTRACT:

Objective

This study examined 12-month neurobehavioral outcomes in children who survived out-of-hospital cardiac arrest (OH-CA), were comatose after resuscitation, and were enrolled in a clinical trial to evaluate targeted temperature management to hypothermia (33.0°C) or normothermia (36.8°C) (Therapeutic Hypothermia after Pediatric Cardiac Arrest, Out-of-Hopsital [THAPCA-OH]; NCT00878644).

Methods

Baseline functioning was assessed by caregiver responses on the Vineland Adaptive Behavior Scales-Second Edition (VABS-II) soon after OH-CA (based on functioning before OH-CA); children with broadly normal baseline functioning (VABS-II ≥70) were included in the THAPCA-OH primary outcome. VABS-II was completed again 12 months later. Then, face-to-face cognitive evaluations were completed. Analyses evaluated changes in VABS-II composite, domain, and subdomain scores and cognitive functioning at follow-up.

Results

Ninety-six of 295 enrolled children were alive at 12 months; 87 of 96 had broadly normal baseline functioning (VABS-II ≥70). Follow-up was obtained on 85/87. Forty-two of 85 had VABS-II ≥70 at 12 months. VABS-II composite, domain, and subdomain scores declined significantly between baseline and 12-month follow-up (P < .001). Declines were greatest in older children. Most children displayed well below average cognitive functioning. Older age at cardiac arrest and higher baseline VABS-II scores were predictive of greater decline in neurobehavioral function. Treatment with hypothermia did not influence neurobehavioral outcomes.

Conclusions

This is the largest study exploring long-term neurobehavioral outcomes in children surviving OH-CA who were comatose after resuscitation. Results revealed significant neurobehavioral morbidity across multiple functional domains, based both on caregiver reports and performance on objective cognitive measures, in survivors 1 year later.

Project description:ObjectivesTo describe survival and 3-month and 12-month neurobehavioral outcomes in children with preexisting neurobehavioral impairment enrolled in one of two parallel randomized clinical trials of targeted temperature management.DesignSecondary analysis of Therapeutic Hypothermia after Pediatric Cardiac Arrest In-Hospital and Out-of-Hospital trials data.SettingForty-one PICUs in the United States, Canada, and United Kingdom.PatientsEighty-four participants (59 in-hospital cardiac arrest and 25 out-of-hospital cardiac arrest), 49 males, 35 females, mean age 4.6 years (SD, 5.36 yr), with precardiac arrest neurobehavioral impairment (Vineland Adaptive Behavior Scales, Second Edition composite score < 70). All required chest compressions for greater than or equal to 2 minutes, were comatose and required mechanical ventilation after return of circulation.InterventionsNeurobehavioral function was assessed using the Vineland Adaptive Behavior Scales, Second Edition at baseline (reflecting precardiac arrest status), and at 3 and 12 months postcardiac arrest, followed by on-site cognitive evaluation. Vineland Adaptive Behavior Scales, Second Edition norms are 100 (mean) ± 15 (SD); higher scores indicate better function. Analyses evaluated survival, changes in Vineland Adaptive Behavior Scales, Second Edition, and cognitive functioning.Measurements and main resultsTwenty-eight of 84 (33%) survived to 12 months (in-hospital cardiac arrest, 19/59 (32%); out-of-hospital cardiac arrest, 9/25 [36%]). In-hospital cardiac arrest (but not out-of-hospital cardiac arrest) survival rate was significantly lower compared with the Therapeutic Hypothermia after Pediatric Cardiac Arrest group without precardiac arrest neurobehavioral impairment. Twenty-five survived with decrease in Vineland Adaptive Behavior Scales, Second Edition less than or equal to 15 (in-hospital cardiac arrest, 18/59 (31%); out-of-hospital cardiac arrest, 7/25 [28%]). At 3-months postcardiac arrest, mean Vineland Adaptive Behavior Scales, Second Edition scores declined significantly (-5; SD, 14; p < 0.05). At 12 months, Vineland Adaptive Behavior Scales, Second Edition declined after out-of-hospital cardiac arrest (-10; SD, 12; p < 0.05), but not in-hospital cardiac arrest (0; SD, 15); 43% (12/28) had unchanged or improved scores.ConclusionsThis study demonstrates the feasibility, utility, and challenge of including this population in clinical neuroprotection trials. In children with preexisting neurobehavioral impairment, one-third survived to 12 months and their neurobehavioral outcomes varied broadly.

Project description:To investigate relationships between cardiac arrest characteristics and survival and neurobehavioral outcome among children recruited to the Therapeutic Hypothermia after Pediatric Cardiac Arrest Out-of-Hospital trial.Secondary analysis of Therapeutic Hypothermia after Pediatric Cardiac Arrest Out-of-Hospital trial data.Thirty-six PICUs in the United States and Canada.All children (n = 295) had chest compressions for greater than or equal to 2 minutes, were comatose, and required mechanical ventilation after return of circulation.Neurobehavioral function was assessed using the Vineland Adaptive Behavior Scales, Second Edition at baseline (reflecting prearrest status) and 12 months postarrest. U.S. norms for Vineland Adaptive Behavior Scales, Second Edition scores are 100 (mean) ± 15 (SD). Higher scores indicate better functioning. Outcomes included 12-month survival and 12-month survival with Vineland Adaptive Behavior Scales, Second Edition greater than or equal to 70.Cardiac etiology of arrest, initial arrest rhythm of ventricular fibrillation/tachycardia, shorter duration of chest compressions, compressions not required at hospital arrival, fewer epinephrine doses, and witnessed arrest were associated with greater 12-month survival and 12-month survival with Vineland Adaptive Behavior Scales, Second Edition greater than or equal to 70. Weekend arrest was associated with lower 12-month survival. Body habitus was associated with 12-month survival with Vineland Adaptive Behavior Scales, Second Edition greater than or equal to 70; underweight children had better outcomes, and obese children had worse outcomes. On multivariate analysis, acute life threatening event/sudden unexpected infant death, chest compressions more than 30 minutes, and weekend arrest were associated with lower 12-month survival; witnessed arrest was associated with greater 12-month survival. Acute life threatening event/sudden unexpected infant death, other respiratory causes of arrest except drowning, other/unknown causes of arrest, and compressions more than 30 minutes were associated with lower 12-month survival with Vineland Adaptive Behavior Scales, Second Edition greater than or equal to 70.Many factors are associated with survival and neurobehavioral outcome among children who are comatose and require mechanical ventilation after out-of-hospital cardiac arrest. These factors may be useful for identifying children at risk for poor outcomes, and for improving prevention and resuscitation strategies.

Project description:BackgroundTherapeutic hypothermia is recommended for comatose adults after witnessed out-of-hospital cardiac arrest, but data about this intervention in children are limited.MethodsWe conducted this trial of two targeted temperature interventions at 38 children's hospitals involving children who remained unconscious after out-of-hospital cardiac arrest. Within 6 hours after the return of circulation, comatose patients who were older than 2 days and younger than 18 years of age were randomly assigned to therapeutic hypothermia (target temperature, 33.0°C) or therapeutic normothermia (target temperature, 36.8°C). The primary efficacy outcome, survival at 12 months after cardiac arrest with a Vineland Adaptive Behavior Scales, second edition (VABS-II), score of 70 or higher (on a scale from 20 to 160, with higher scores indicating better function), was evaluated among patients with a VABS-II score of at least 70 before cardiac arrest.ResultsA total of 295 patients underwent randomization. Among the 260 patients with data that could be evaluated and who had a VABS-II score of at least 70 before cardiac arrest, there was no significant difference in the primary outcome between the hypothermia group and the normothermia group (20% vs. 12%; relative likelihood, 1.54; 95% confidence interval [CI], 0.86 to 2.76; P=0.14). Among all the patients with data that could be evaluated, the change in the VABS-II score from baseline to 12 months was not significantly different (P=0.13) and 1-year survival was similar (38% in the hypothermia group vs. 29% in the normothermia group; relative likelihood, 1.29; 95% CI, 0.93 to 1.79; P=0.13). The groups had similar incidences of infection and serious arrhythmias, as well as similar use of blood products and 28-day mortality.ConclusionsIn comatose children who survived out-of-hospital cardiac arrest, therapeutic hypothermia, as compared with therapeutic normothermia, did not confer a significant benefit in survival with a good functional outcome at 1 year.

Project description:To describe family burden among caregivers of children who survived out-of-hospital cardiac arrest and who were at high risk for neurologic disability and examine relationships between family burden, child functioning, and other factors during the first year post arrest.Secondary analysis of data from the Therapeutic Hypothermia after Pediatric Cardiac Arrest Out-of-Hospital trial.Thirty-six PICUs in the United States and Canada.Seventy-seven children recruited to the Therapeutic Hypothermia after Pediatric Cardiac Arrest Out-of-Hospital trial who had normal prearrest neurologic functioning and were alive 1 year post arrest.Family burden was assessed using the Infant Toddler Quality of Life Questionnaire for children less than 5 years old and the Child Health Questionnaire for children 5 years old or older at baseline (reflecting prearrest status), 3 months, and 12 months post arrest. Child functioning was assessed using the Vineland Adaptive Behavior Scale II, the Pediatric Overall Performance Category, and Pediatric Cerebral Performance Category scales and caregiver perception of global functioning.Fifty-six children (72.7%) were boys, 48 (62.3%) were whites, and 50 (64.9%) were less than 5 years old prior to out-of-hospital cardiac arrest. Family burden at baseline was not significantly different from reference values. Family burden was increased at 3 and 12 months post arrest compared with reference values (p < 0.001). Worse Pediatric Overall Performance Category and Pediatric Cerebral Performance Category, lower adaptive behavior, lower global functioning, and higher family burden all measured 3 months post arrest were associated with higher family burden 12 months post arrest (p < 0.05). Sociodemographics and prearrest child functioning were not associated with family burden 12 months post arrest.Families of children who survive out-of-hospital cardiac arrest and have high risk for neurologic disability often experience substantial burden during the first year post arrest. The extent of child dysfunction 3 months post arrest is associated with family burden at 12 months.
