The aim of this study was to identify the main predictors of death in hospitalized patients.Patients and Methods: In the period from 1 March 2020 to 30 June 2021, an observational, retrospective, randomized, case-control study was conducted, which included a sample of 139 patients who died in hospital and another sample of 275 patients who had been discharged in an improved or healed condition. Confirmation of COVID-19 cases was performed by RT-PCR from nasopharyngeal and oropharyngeal exudates. Statistical data were analyzed by logistic regression, Cox regression and a comparison of survival curves by the log-rank (Mantel-Cox) test.Results: The most powerful logistic regression model identified the following independent predictors of death: history of coagulopathy HR = 30.73 [1.94– 487.09], p = 0.015; high percentage of neutrophils HR = 1.09 [1.01– 1.19], p = 0.027; and decreased blood-oxygenation HR = 53881.97 [1762.24– 1647489.44], p < 0.001. Cox regression identified the following factors that influenced the evolution of cases: history of coagulopathy HR = 2.44 [1.38– 4.35], p = 0.000; O2 saturation HR = 0.98 [0.96– 0.99], p = 0.043; serum creatinine HR = 1.23 [1.08– 1.39], p = 0.001; dyspnea on admission HR = 2.99 [1.42– 6.30], p = 0.004; hospitalization directly in the ICU HR = 3.803 [1.97– 7.33], p < 0.001; heart damage HR = 16.76 [1.49– 188.56], p = 0.022; and decreased blood-oxygenation HR = 35.12 [5.92– 208.19], p < 0.001.Conclusion: Knowledge of the predictors of death in hospitalized patients allows for the future optimization of triage and therapeutic case management for COVID-19.Keywords: complications, comorbidities, COVID-19, protection factors, risk factors, survival
