Insights
Infants admitted for apparent life-threatening events (ALTE) face a significant risk of post-discharge mortality, with two deaths occurring within two weeks of their emergency department visit. Emergency physicians should consider routine admission for these patients.
Area of Science:
- Pediatric Emergency Medicine
- Neonatal Care
- Clinical Outcomes Research
Background:
- Apparent life-threatening events (ALTE) are a common reason for pediatric emergency department visits.
- Understanding post-discharge mortality risk in infants with ALTE is crucial for clinical management.
Purpose of the Study:
- To investigate the mortality rate in clinically stable infants after hospital discharge following their first apparent life-threatening event (ALTE).
Main Methods:
- A retrospective chart review was conducted on infants aged 0-6 months presenting with their first ALTE over a 5-year period.
- Inclusion criteria were applied, and physician reviewers assessed patient charts.
- Mortality data was cross-referenced with county death records and hospital records.
Main Results:
- Of 176 infants meeting inclusion criteria, 1.1% (2 patients) died post-discharge, both within two weeks of their emergency department visit.
- Neither of the deceased infants had positive diagnostic evaluations during their emergency department stay.
- Pneumonia was identified as the cause of death in both fatalities.
Conclusions:
- Infants admitted to the hospital for an apparent life-threatening event (ALTE) have a substantial risk of subsequent mortality.
- Routine hospital admission should be considered by emergency physicians for infants presenting with ALTE.
Objective:
The objective of this study is to review the mortality after discharge in clinically stable infants admitted with a first apparent life-threatening event.
Design:
Retrospective chart review of all infants 0 to 6 months presenting with a first apparent life-threatening event (ALTE) over a 5-year period using explicit criteria. Patients with an emergency department (ED) diagnosis of ALTE, seizure, choking spell, or cyanosis were reviewed by 2 of 3 physicians. Level of agreement between reviewers was monitored. Mortalities were identified by a review of the county death record database and hospital records.
Results:
Three hundred sixty-six charts were reviewed; 176 cases met inclusion criteria. All apparent life-threatening event (ALTE) cases were admitted; 1 signed out against medical advice. Blood cultures were obtained in 111 patients (63%)-no pathogens were identified. Cerebrospinal fluid analysis and culture was performed in 65 patients (37%)-no pathogens were identified. One patient had pleocytosis. Chest radiographs were obtained in 115 patients (65%); 12 patients had infiltrates. Respiratory syncytial virus nasal washings were obtained in 32% of patients and were positive in 9 patients. The average length of follow-up was 34 months; 2 patients (1.1%) had died at the time of follow-up. Both deaths occurred after hospital discharge and within 2 weeks of the ED visit. Neither of the fatalities had a positive diagnostic evaluation in the ED. The cause of death by coroner report was pneumonia in both instances.
Conclusions:
The risk of subsequent mortality in infants admitted from our pediatric ED with an ALTE is substantial. Emergency physicians should consider routine admission for patients with ALTE.

Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
