Incidence, Causes, and Outcome of Out-of-Hospital Cardiac Arrest in Children: A Comprehensive Study in the Netherlands

This study provides a comprehensive analysis of the incidence, causes, and outcome of pediatric out-of-hospital cardiac arrest (OHCA) in the Netherlands. The data includes information on survival rates and neurological outcomes of resuscitated patients.

  2. Background • There is a paucity of complete studies on incidence, causes and outcome of pediatric out-of-hospital cardiac arrest (OHCA) • Previous large studies only included OHCA cases that involved emergency medical services (EMS) • Few studies reported the single (groups of) causes of pediatric OHCA J Am Coll Cardiol 2011;57:1822-8

  3. Objective • To comprehensively determine: • The incidence of pediatric OHCA • The contribution of OHCA to total pediatric mortality, • The causes of pediatric OHCA • The outcome of resuscitation of pediatric OHCA patients J Am Coll Cardiol 2011;57:1822-8

  4. Setting • Prospective population-based study of children suffering OHCA between October 1, 2005 and February 1, 2010 in the North-Holland province of The Netherlands • Population: 2.4 million people, including 588,389 aged <21 years J Am Coll Cardiol 2011;57:1822-8

  5. Assessment of cardiac and non-cardiac cause of OHCA • OHCA was non-cardiac when EMS rescuers, hospital physicians or coroners identified a natural, non-cardiac cause or non-natural cause • All other cases had a (presumed) cardiac cause and were termed cardiac OHCA J Am Coll Cardiol 2011;57:1822-8

  6. Death certificate data • We retrieved death certificate data from Statistics Netherlands, a Dutch governmental institution that collects age/gender-specific statistics of all deaths in The Netherlands to: • Establish the contribution of OHCA to total mortality in pediatric age groups • Gain insight into the completeness of our data collection J Am Coll Cardiol 2011;57:1822-8

  7. Survival analysis • We analyzed only truly resuscitatable OHCA cases by excluding OHCA victims who were found dead by EMS personnel upon arrival • Survival status at hospital discharge obtained by contacting the designated hospital • The pediatric Cerebral Performance Category (CPC) of each patient was estimated by reviewing the hospital charts J Am Coll Cardiol 2011;57:1822-8

  8. Patient characteristics • 233 pediatric OHCA cases • 83 EMS-only, 100 coroners-only cases, 50 cases registered by both sources • 24% of total pediatric mortality • We registered 90 (87%) of the 103 potential pediatric cardiac OHCA cases according to the death certificate data, and 143 (99%) of the 144 potential pediatric non-cardiac OHCA cases J Am Coll Cardiol 2011;57:1822-8

  9. Incidences of pediatric OHCA Data are expressed as number per 100,000 pediatric person-years (95% confidence interval). Adjusted by age/sex to the European Union population J Am Coll Cardiol 2011;57:1822-8

  10. Causes of out-of-hospital cardiac arrest J Am Coll Cardiol 2011;57:1822-8

  11. Survival and neurologic outcome • CPR was initiated in 69 OHCA victims, but only 51 were truly resuscitatable • Of 51 resuscitated patients, 12 (24%) survived • 29% [4/14] in infants, 12% [2/17] in children, 30% [6/20] in adolescents (NS) • 10/12 (83%) had a neurologically-intact outcome • 83% (75% [3/4] in infants, 100% [2/2] in children, 83% [5/6] in adolescents J Am Coll Cardiol 2011;57:1822-8

  12. Operational characteristics of resuscitated victims of OHCA from cardiac causes J Am Coll Cardiol 2011;57:1822-8

  13. Conclusions • OHCA accounts for a significant proportion of pediatric mortality • Cardiac causes are the most prevalent causes of OHCA • The vast majority of OHCA survivors have a neurologically-intact outcome J Am Coll Cardiol 2011;57:1822-8
