Objective: to evaluate the clinical conditions and the risk classification of children and adolescents treated in a hospital emergency, according to the Pediatric Risk Classification Protocol.
Method: cross-sectional study, with 200 participants, using an instrument based on the Pediatric Risk Classification Protocol and using odds ratio for the analysis.
Results: most participants were male patients in early childhood and who were or weren't in daycare. As for clinical conditions, most showed changes in vital (24.5%) and respiratory (20.0%) signs, most patients (57.5%) did not present pain; 35.5% were classified as urgent and 45.0% as non-urgent. There was a greater chance of being classified as very urgent (orange) when compared to non-urgent (blue).
Conclusion: the protocol used contributed to an effective classification and was considered a valid and reliable health technology for determining the priority of care.
