“…Elderly patients with COVID-19 are subject to progress to a severe disease, as they are more susceptible to a multisystem organ dysfunction and even organ failure. Furthermore, it was observed that the presence of lung lesions on imaging examinations and the number of white blood cells and neutrophils in laboratory examinations were significantly higher in the older patients group compared to the young and middle-aged group, thus suggesting that the former is also more prone to acquire a bacterial coinfection [ 11 , 21 , 22 , 23 ].…”

Objective: To analyze the survival of patients hospitalized with COVID-19 and its associated factors. Methods: Retrospective study of survival analysis in individuals notified and hospitalized with COVID-19 in the state of Espírito Santo, Brazil. As data source, the reports of hospitalized patients in the period from 1 March 2020, to 31 July 2021 were used. The Cox regression analysis plus the proportional risk assessment (assumption) were used to compare hospitalization time until the occurrence of the event (death from COVID-19) associated with possible risk factors. Results: The sample comprised 9806 notifications of cases, with the occurrence of 1885 deaths from the disease (19.22%). The mean age of the group was 58 years (SD ± 18.3) and the mean hospital length of stay was 10.5 days (SD ± 11.8). The factors that presented a higher risk of death from COVID-19, associated with a lower survival rate, were non-work-related infection (HR = 4.33; p < 0.001), age group 60–79 years (HR: 1.62; p < 0.001) and 80 years or older (HR = 2.56; p < 0.001), presence of chronic cardiovascular disease (HR = 1.18; p = 0.028), chronic kidney disease (HR = 1.5; p = 0.004), smoking (HR = 1.41; p < 0.001), obesity (HR = 2.28; p < 0.001), neoplasms (HR = 1.81; p < 0.001) and chronic neurological disease (HR = 1.68; p < 0.001). Conclusion: It was concluded that non-work-related infection, age group above or equal to 60 years, presence of chronic cardiovascular disease, chronic kidney disease, chronic neurological disease, smoking, obesity and neoplasms were associated with a higher risk of death, and, therefore, a lower survival in Brazilian patients hospitalized with COVID-19. The identification of priority groups is crucial for Health Surveillance and can guide prevention, control, monitoring, and intervention strategies against the new coronavirus.

“…Research conducted in Lombardy, Italy, and in the Northeast region of Brazil identified that age and survival are inversely proportional, with younger age groups showing a higher probability of survival compared to the older ones (Grasselli et al, 2020;Nascimento, 2021). Age and the presence of comorbidity have been identified as the main determinants of death (.…”

Objective: To evaluate survival and risk of mortality in COVID-19 patients admitted to a public hospital located in the Legal Amazon. Method: A retrospective longitudinal documentary study, in which 196 medical records of patients admitted from April to August 2020, at the General Hospital of Palmas, diagnosed with COVID-19, were assessed. Socioeconomic data, age, sex, comorbidities, and disease outcome were collected from the records. Results: The average age was 58.6±16 years. Male sex was predominant (66.8%) and individuals with comorbidities (77%). It was observed that 76.14% of the patients were between 40 and 80 years of age. The Kaplan-Meier curve demonstrated a decline in survival over time, indicating that the likelihood of a patient surviving for 16 days is around 50%. The Log-rank test showed a statistical difference for the variables age (p = 0.01) and cancer (p = 0.02), suggesting a reduction in the probability of survival in older patients with cancer. The Cox regression identified that the risk of death in patients between 60 and 79 years was approximately 3 times higher than in those aged 40, while in those aged 80 or older, it was 6 times higher. In the same model, the risk of death in patients with obesity was 98% higher, and 2.11 times higher in patients with cancer. Conclusions: The research provided important insights into the behavior of COVID-19 in the Legal Amazon, which will support the response to the virus and other health crises.
