Introduction:

An apparent life-threatening event (ALTE) is a frequent cause of hospitalization in infants. However, there is little evidence about the existence of a standardized approach to discover the main etiology, although a correct causal diagnosis can affect clinical evolution, hospital stay, and health resources.

Objective:

To determine the effects of a standardized diagnostic approach in infants admitted with ALTE.

Materials and methods:

We conducted a retrospective cohort study with the data collected from clinical records of infants hospitalized for ALTE in the pediatric unit between 2002 and 2009. Two cohorts of patients were analyzed according to the procedures defined for these cases: Cohort 1 with clinical guidelines and cohort 2 with clinical guidelines, study protocol, and outpatient follow-up. Etiological causes, hospitalization periods and readmission rates were compared between both cohorts.

Results:

Of the 255 infants hospitalized for ALTE, 57.6% corresponded to cohort 1 and 42.3% to cohort 2. No differences were observed in age and gender between groups. The highest percentage of attributed causes (63.9 vs 87.0%; p<0.0001) and a shorter period of hospitalization (8.0 vs 5.0 days; p=0, 0001) were observed in cohort 2. No differences in hospital readmission were observed (10.5 vs 8.3 days; p=0.7435).

Conclusions:

The protocol-based approach for infants with EAL was associated with a higher percentage of recognition of attributed causes and a shorter hospitalization period. Therefore, our results allow recommending this type of standardization for the management of these patients.
