BACKGROUND: Amid the overcrowding of healthcare services in Brazil, the early identification of critically ill COVID-19 patients becomes essential.
AIMS: This study aims to evaluate the ability of the Modified Early Warning Score (MEWS) and Triage Early Warning Score (TREWS) to predict severity and mortality in hospitalized COVID-19 patients.
METHODS: In this retrospective cohort study, patients hospitalized with COVID-19 at the Instituto de Infectologia Emílio Ribas (IIER) were included. MEWS and TREWS scores were calculated based on patients' vital signs at the time of admission to IIER.
RESULTS: The study included 579 patients, predominantly male (60.45%), with a mean age of 52.54 years. Comorbidities such as diabetes mellitus (23.32%) and systemic arterial hypertension (41.28%) were common. Most patients were not fully vaccinated against COVID-19 (65.46%). The estimated 14-day survival was 75.10% for patients with MEWS ≤ 3.5 at admission and 56.50% for those with MEWS > 3.5 at admission (p < 0.001). The 14-day survival for patients with a TREWS ≤ 7.5 was 78.00%, compared to 52.80% for those with a TREWS > 7.5 (p < 0.001). Each additional point in MEWS was associated with a 1.33-fold increase in the odds of ICU admission (p < 0.001) and 1.51-fold increase in the odds of death (p < 0.001). Each additional point in TREWS was associated with a 1.36-fold increase in ICU admission (p < 0.001) and 1.49-fold increase in death (p < 0.001).
CONCLUSIONS: Both scores demonstrated the ability to identify critically ill patients at the time of admission.
