Improved outcomes after successful implementation of a pediatric early warning system (PEWS) in a resource-limited pediatric oncology hospital.

Background: Hospitalized pediatric oncology patients are at high risk of clinical decline and mortality, particularly in resource-limited settings. Pediatric early warning systems (PEWS) aid in the early identification of clinical deterioration; however, there are limited data regarding their feasibility or impact in low-resource settings. This study describes the successful implementation of PEWS at the Unidad Nacional de Oncología Pediátrica (UNOP), a pediatric oncology hospital in Guatemala, resulting in improved inpatient outcomes.
