Mortality after discharge in clinically stable infants admitted with a first-time apparent life-threatening event.

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.
