Risk Factors for Mortality in Hospitalized Moderate‑to‑Severe COVID‑19 Patients: A Single‑center Retrospective Study
The aim of this study was to determine the mortality risk factors of hospitalized moderate‑to‑severe coronavirus disease 2019 (COVID‑19) patients in Tehran.
We retrospectively evaluated the baseline characteristics and clinical and paraclinical parameters of 223 deceased and discharged patients who were hospitalized in Firoozabadi General Hospital between March 1 and April 1, 2020.
According to our multiple logistic regression model, advanced age (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.02–1.09; P < 0.01), reduced oxygen saturation (OR, 0.92; 95% CI, 0.87–0.96; P < 0.01), and hypertension (OR, 2.59; 95% CI, 1.04–6.46; P = 0.04) can be perceived as independent risk factors for mortality.
Our results suggest that patients with older age, lower oxygen saturation, and hypertension are predisposed to an increased risk of mortality. Thus, to lower the COVID‑19 mortality rates, patients with these characteristics should be the primary targets for early treatment, vaccination, or monitoring strategies.
