Insights
Hospitals with Extracorporeal Membrane Oxygenation (ECMO) capability showed higher survival rates for pediatric cardiac arrest patients. This suggests ECMO availability is linked to better outcomes in children experiencing cardiac arrest.
Area of Science:
- Pediatric critical care medicine
- Cardiovascular research
- Health services research
Background:
- Extracorporeal membrane oxygenation (ECMO) is a life-support technology for severe cardiac or respiratory failure.
- Its impact on survival rates for pediatric cardiac arrest is not well understood.
- Evaluating hospital ECMO capability is crucial for improving outcomes in critically ill children.
Purpose of the Study:
- To determine if a hospital's Extracorporeal Membrane Oxygenation (ECMO) capability is associated with improved survival rates in children who suffer cardiac arrest.
- To analyze the relationship between pediatric cardiac arrest survival and the availability of ECMO services at the treating hospital.
Main Methods:
- Utilized the Health Care Utilization Project (HCUP) National Inpatient Sample (NIS) database from 2016-2018.
- Identified pediatric (0-18 years) cardiac arrest hospitalizations, including in- and out-of-hospital cases.
- Employed hierarchical logistic regression to assess the association between hospital ECMO capability and in-hospital survival.
Main Results:
- A total of 1276 pediatric cardiac arrest hospitalizations were analyzed, with an overall survival rate of 44%.
- Hospitals with ECMO capability demonstrated a higher survival rate (50%) compared to non-ECMO hospitals (32%).
- Care at an ECMO-capable hospital was associated with significantly higher in-hospital survival (OR 1.49, 95% CI 1.09-2.02), even after adjusting for patient and hospital factors.
Conclusions:
- Hospital Extracorporeal Membrane Oxygenation (ECMO) capability is associated with increased in-hospital survival for pediatric cardiac arrest patients.
- Further research is needed to explore care delivery variations and organizational factors influencing pediatric cardiac arrest outcomes.
- These findings highlight the importance of ECMO availability in improving survival for critically ill children.
Aim:
Extracorporeal membrane oxygenation (ECMO) provides temporary support in severe cardiac or respiratory failure and can be deployed in children who suffer cardiac arrest. However, it is unknown if a hospital's ECMO capability is associated with better outcomes in cardiac arrest. We evaluated the association between pediatric cardiac arrest survival and the availability of pediatric extracorporeal membrane oxygenation (ECMO) at the treating hospital.
Methods:
We identified cardiac arrest hospitalizations, including in- and out-of-hospital, in children (0-18 years old) using data from the Health Care Utilization Project (HCUP) National Inpatient Sample (NIS) between 2016 and 2018. The primary outcome was in-hospital survival. Hierarchical logistic regression models were built to test the association between hospital ECMO capability and in-hospital survival.
Results:
We identified 1276 cardiac arrest hospitalizations. Survival of the cohort was 44%; 50% at ECMO-capable hospitals and 32% at non-ECMO hospitals. After adjusting for patient-level factors and hospital factors, receipt of care at an ECMO- capable hospital was associated with higher in-hospital survival, with an odds ratio of 1.49 [95% CI 1.09, 2.02]. Patients who received treatment at ECMO-capable hospitals were younger (median 3 years vs 11 years, p < 0.001) and more likely to have a complex chronic condition, specifically congenital heart disease. A total of 10.9% (88/811) of patients at ECMO-capable hospitals received ECMO support.
Conclusion:
A hospital's ECMO capability was associated with higher in-hospital survival among children suffering cardiac arrest in this analysis of a large United States administrative dataset. Future work to understand care delivery differences and other organizational factors in pediatric cardiac arrest is necessary to improve outcomes.
