ABSTRACT
BACKGROUND: The Pediatric Canadian Triage and Acuity Scale (PedCTAS) is a recognized system that prioritizes care by the severity of illness. The goal of this study was to describe and analyze the results from the implementation of the PedCTAS in a tertiary children's hospital in Costa Rica. METHODS: This was a retrospective observational study of children presenting to the emergency department (ED) from 1st January to 31st December of 2019 in the only children's hospital in Costa Rica. Outcome measures were hospitalization, ICU admission, waiting times from triage to physician time (TPT), left without being seen (LWBS), length of stay (LOS), in relation to the triage level, and final disposition. RESULTS: A total of 93,001 patients were admitted to the ED. The proportion for hospitalizations according to triage category was 85.3%, 40%, 14%, 4.3%, and 2% for patients triaged at CTAS levels I, II, III, IV, and V respectively. A total of 2045 (2.19%) patients were LWBS. Some 585 (0.62%) patients were admitted to ICU. Median TPT for each category was for levels I:12 min, II:20 min, III:22 min, IV:34 min, and V:54 min. The LOS in the ED patients triaged as levels I and II stayed longer and the mortality rate was also higher in patients classified as levels I and II. The mortality rate was for level I patients 44.2% (23 patients) and level II 1.4% (8 patients). CONCLUSIONS: This study shows evidence of validation of the PedCTAS in a developing country in Latin America. Implementation of a validated triage tool in our country helps us to provide improvements in the care of pediatric patients in the ED.
