Abstract

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.
