Triage performance in adolescent patients with SARS-CoV-2 infection in Israel

Objective: The aim of this study was to assess the performance of the Pediatric Canadian Triage and Acuity Scale (PaedCTAS) in adolescent patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Methods: A time-series study was conducted in the Emergency Departments (EDs) of 17 public hospitals during the Delta (B.1.617.2) variant spread in Israel. Data were collected prospectively from June 11, 2021 to August 15, 2021. Multivariate regression analyses were performed to identify independent variables associated with hospital admission and with admission to an Intensive Care Unit (ICU). Results: During the study period, 305 SARS-CoV-2 patients ages 12–18 years presenting to the ED were included, and 267 (87.5%) were unvaccinated. Sixty-seven (22.0%) and 12 (3.9%) patients were admitted to pediatric wards and ICUs, respectively. PaedCTAS level 1–2 and the presence of chronic disease increased the odds of hospital admission (adjusted odds ratio (aOR) 5.74, 95% CI, 2.30–14.35, p < 0.0001), and (aOR 2.9, 95% CI, 1.48–5.67, p < 0.02), respectively. PaedCTAS level 1–2 and respiratory symptoms on presentation to ED increased the odds of ICU admission (aOR 27.79; 95% CI, 3.85–176.91, p < 0.001), and (aOR 26.10; 95% CI, 4.47–172.63, p < 0.0001), respectively. PaedCTAS level 3–5 was found in 217/226 (96%) of the patients who were discharged home from the ED. Conclusions: The findings suggest that PaedCTAS level 1–2 was the strongest factor associated with hospital and ICU admission. Almost all the patients who were discharged home had PaedCTAS level 3–5. Study findings suggest good performance of the PaedCTAS in this cohort.
