Survival and risk of death in Covid-19 patients admitted to a public hospital in the Legal Amazon

Abstract

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.
