Risk Factors For Mortality Among Patients With Sars-Cov-2 Infection: A Longitudinal Observational Study

Recent literature suggests that approximately 5%-18% of patients diagnosed with severe acute respiratory syndrome coronavirus 2 may progress rapidly to a severe form of the illness and subsequent death. We examined the relationship between sociodemographic, clinical, and laboratory findings with mortality among patients. In this study, 112 patients were evaluated from February to May 2020 and 80 patients met the inclusion criteria. Tocilizumab was administered, followed by methylprednisolone to patients with pneumonia severity index score <= 130 and computerized tomography scan changes. Demographic data and clinical outcomes were collected. Laboratory biomarkers were monitored during hospitalization. Statistical analyses were performed with significancep <= .05. A total of 80 patients: 45 males (56.25%) and 35 females (43.75%) met the study inclusion criteria. A total of 7 patients (8.75%) were deceased. An increase in mortality outcome was statistically significantly associated with higher average levels of interleukin-6 (IL-6) withpvalue (.050), andd-dimer withpvalue (.024). Bivariate logistics regression demonstrated a significant increased odds for mortality for patients with bacterial lung infections (odds ratio [OR]: 10.83; 95% confidence interval [CI]: 2.05-57.40;p = .005) and multiorgan damage (OR: 103.50; 95% CI: 9.92-1079.55;p = .001). Multivariate logistics regression showed a statistically significant association for multiorgan damage (adjusted odds ratio [AOR]: 94.17; 95% CI: 7.39-1200.78;p = .001). We identified three main predictors for high mortality. These include IL-6, d-dimer, and multiorgan damage. The latter was the highest potential risk for in-hospital deaths. This warrants aggressive health measures for early recognition of the problem and initiation of treatment to reverse injuries.
