Insights
Most pediatric out-of-hospital cardiac arrest (OHCA) patients had prior medical conditions, with psychiatric disorders being common. Trauma was a frequent cause of OHCA, especially in those with psychiatric histories.
Area of Science:
- Pediatric Emergency Medicine
- Cardiology
- Public Health
Background:
- Out-of-hospital cardiac arrest (OHCA) in children is a critical medical emergency.
- Understanding pre-existing conditions in pediatric OHCA patients is crucial for risk stratification and prevention strategies.
Purpose of the Study:
- To investigate the medical history of pediatric OHCA patients.
- To identify pre-existing medical or surgical conditions associated with OHCA in children.
Main Methods:
- Retrospective population-based cohort study in Helsinki.
- Inclusion of all pediatric OHCA patients (0-17 years) attended by emergency medical services (EMS) from 2002-2011.
- Review of medical records for pre-existing conditions.
Main Results:
- Forty-three pediatric OHCA cases were identified.
- The leading causes of OHCA were trauma (30.2%), sudden infant death syndrome (18.6%), and cardiac issues (14.0%).
- A majority of patients (65.1%) had prior medical records, with common conditions including perinatal adaptation abnormalities (20.9%), psychiatric treatment (16.3%), and epilepsy (13.9%).
- Trauma-related OHCA was more common in patients with prior psychiatric diagnoses.
- Half of 17-year-old OHCA patients had psychiatric records.
Conclusions:
- Most pediatric OHCA patients have a history of significant medical conditions.
- Psychiatric disorders were notably prevalent among pediatric OHCA patients.
- Pre-existing conditions, particularly psychiatric disorders, may be linked to OHCA risk in children.
Objective:
The aim of this study was to examine the medical history of the pediatric out-of-hospital cardiac arrest (OHCA) patients to determine preexisting conditions that may relate to a later OHCA.
Methods:
The study was a retrospective population-based cohort study in Helsinki (population 595,000) served by a single emergency medical service (EMS) system. All OHCA patients aged between 0 and 17 met by the local EMS from 2002 to 2011 were included. Medical records of the Helsinki University Hospital and its clinics were examined to find preexisting medical or surgical conditions.
Results:
Forty-three patients experienced an EMS-treated OHCA. The annual incidence of an EMS-treated OHCA was 4.4 per 100,000 population younger than the age of 18 years. The mean age of patients was 7.9 years, largest age groups being younger than 1 year (30.2%) and 17 years (23.2%). The leading cause of OHCA was trauma (30.2%) followed by sudden infant death syndrome (18.6%) and cardiac reasons (14.0%). Nine patients (20.9%) survived to hospital, and 5 (11.6%) were discharged alive. Of the 43 patients, 28 (65.1%) had prior medical records in Helsinki University Hospital considering suspected or diagnosed chronic or otherwise significant conditions. The most common conditions were perinatal adaptation abnormalities (20.9%), psychiatric treatment (16.3%), and epilepsy (13.9%). Five patients had previous cardiac conditions. Trauma as a cause of OHCA was frequently represented among patients with prior psychiatric diagnosis or treatment. Among 17-year-old OHCA patients, 5 of 10 had psychiatric records.
Conclusions:
Majority of the patients had prior medical records. Psychiatric disorders were strongly presented.
