RESUMO
OBJECTIVE: The ESI algorithm is widely used to triage patients in the emergency room. However, few studies have assessed the reliability of ESI to accurately triage trauma patients. The aim of this study was to compare vital signs, resource utilization, and patient outcomes among trauma patients during the pandemic in 2020 vs. the previous year prior to the pandemic. METHODS: This retrospective study was conducted over a 24-month period at an urban adult level one trauma center. Demographic and clinical characteristics, resource utilization, and patient outcomes were extracted from the electronic medical records and trauma registry. Trauma patients assigned ESI level 2 were stratified by age (<65 years and ≥ 65 years) and year (2019 vs. 2020) for data analysis. RESULTS: A total of 3,788 trauma patients were included in the study. Males represented 68.4% (2,591) of patients and the median age was 50 years (IQR: 31, 69). The majority of patients were assigned ESI level 2 (2,162, 57.1%) and had a blunt mechanism of injury (3,122, 82.4%). In 2020, patients <65 years of age utilized less resources compared to 2019 (p < 0.001). Likewise, patients >65 years of age required less lab tests [OR: 0.1, 95% CI: (0.05 - 0.4)], IV fluids [OR: 0.2, 95% CI: (0.2 -0.3)], IV medications [OR: 0.6, 95% CI: (0.4 - 0.7)], and specialty consultations [OR: 0.4, 95% CI: (0.3 -0.5)] compared to 2019 (p < 0.0001). Within 2020, vital signs and resources utilized between younger and elderly patients varied significantly (p < 0.01). Correspondingly, the clinical outcomes between younger and elderly patients within 2020, differed significantly (p < 0.01). CONCLUSIONS: The COVID-19 pandemic affected the triage of trauma patients. During 2020, patients utilized less resources compared to the previous year. Additionally, younger and elderly patients had different vital signs, resource utilization, and clinical outcomes although both being assigned ESI level 2. Younger trauma patients may have been over-triaged in 2020 due to the COVID-19 pandemic.
