Objective.

To determine the prevalence and factors associated with intensive care unit admission in children and adolescents with community-acquired pneumonia.

Materials and methods.

Analytical cross-sectional observational study at the Instituto Nacional de Salud del Niño San Borja in 2019. The sample consisted of children older than one month and younger than 18 years who were admitted to emergency diagnosed with community-acquired pneumonia. We used Poisson regression to assess association.

Results.

We evaluated 166 patients diagnosed with pneumonia, 94 (56.6%) were male and the median age was 24 months (IQR: 11 - 48). Most patients had a mild modified PIRO score of 136 (81.9%); 31 (18.7%) patients had complicated pneumonia and 24 (14.5%) were admitted to intensive care. The higher the age, the lower the prevalence of admission to ICU (PR=0.99, 95%CI: 0.98-0.99). The severity assessed with the modified PIRO score (PR=3.40, 95%CI: 1.46-7.93) and the presence of complicated pneumonia (PR: 5.88, 95%CI: 2.46-14.06) were associated with admission to intensive care.

Conclusions.

The prevalence of admission to intensive care in children with community-acquired pneumonia was 14.5%. Younger patients with pneumonia, with greater severity assessed with the modified PIRO score and with complicated pneumonia have a higher prevalence of admission to intensive care.
