Introducción: Conocer el perfil epidemiológico de las consultas pediátricas atendidas en el servicio de urgencia (SU) es esencial para planificar los procesos de atención médica y orientar los programas de educación e investigación. Objetivos: Describir las características de la población infantil y los principales motivos de consulta (MC) atendidos en un SU pediátrico. Pacientes y Método: Estudio clínico descriptivo retrospectivo de las visitas realizadas a un SU infantil en un hospital académico de Santiago durante un período de doce meses. Se analizaron los MC por grupo etario, gravedad, estacionalidad, forma de egreso y frecuencia de visitas recurrentes. Resultados: Se evaluaron 24.531 consultas pediátricas, 51,9% (n = 12.720) eran varones. La edad de los pacientes osciló entre un día y 15 años, con una mediana de 36,5 meses. El 1,5% de los pacientes (n = 362) eran recién nacidos (RN), 17,6% (n = 4.326) lactantes, 51,9% (n = 12.725) preescolares y 29% (n = 7.118) escolares. Los principales MC fueron fiebre (n = 6.643, 28,2%), síntomas gastrointestinales (n = 5.606, 23,8%) y síntomas respiratorios (n = 5.018, 21,3%), los cuales no difirieron significativamente según género. La mayoría de los pacientes (95,5%) fueron enviados a su domicilio. El riesgo de hospitalización fue más elevado en los RN y en aquellos que consultaron por ictericia (OR = 7,20; IC 95% 3,12-16,6), síntomas neurológicos (OR = 6,90; IC 95% 4,60-10,4) e intoxicaciones (OR = 6,45; IC 95% 2,82-14,7). Alrededor del 4% fueron consultas repetidas, especialmente en los RN. Conclusiones: El perfil epidemiológico de las consultas pediátricas atendidas en el SU fue similar al descrito en estudios internacionales. Sin embargo, encontramos una menor tasa de hospitalización a pesar que los pacientes presentaban un perfil de riesgo similar en la admisión al SU. Introduction: To determine the epidemiological profile of pediatric consultations treated at the emergency department (ED) is essential for planning processes of medical care and to guide education programs and research. Objectives: To describe the characteristics of the child population and the main reasons for consultation (RFC) seen in a pediatric emergency service. Patients and Method: A retrospective, descriptive clinical study was conducted regarding the visits to the Children's Emergency Service of an academic hospital in Santiago, for a period of twelve months. RFC were analyzed by age group, severity, seasonality, disposition and frequency of recurrent visits. Results: 24,531 pediatric consultations were evaluated, 51.9% were male (n = 12,720). The age of the patients ranged between one day old and 15 years, with a median age of 36.5 months. 1.5% of patients were newborns (NB), 17.6% were infants (n = 4,326), 51.9% were preschoolers (n = 12,725) and 29% were school children (n = 7,118). Major RFC were fever (n = 6,643, 28.2%), gastrointestinal symptoms (n = 5,606, 23.8%) and respiratory symptoms (n = 5,018, 21.3%), which did not differ significantly according to gender. Most patients (95.5%) were sent to their homes. The risk of hospitalization was more elevated in NB and in those with jaundice (OR = 7.20, 95% CI 3.12 to 16.6), neurological symptoms (OR = 6.90, 95% CI 4.60 -10.4) and poisoning (OR = 6.45, 95% CI 2.82 to 14.7). About 4% were repeat visits, especially in the NB group. Conclusions: The epidemiological profile of pediatric consultations seen at the ED was similar to that described in previous studies. However, a lower rate of hospitalization was found even though the patients had similar risk profile.
