Abstract
Objective: Discover patterns of clinical condition using data from patients of working age who were fully vaccinated against Covid-19, hospitalized due to the severe form of the disease, according to Intensive Care Unit (ICU) admission status in Brazil. Methods: This is a descriptive study with data extracted from the OpenDataSUS database using Association Rules Mining (ARM). Results: Information related to 3,470 individuals was described, of which 53% (n= 1,842) were male, 63% (n= 2,187) with comorbidities, 33% (n= 1,137) were admitted to the ICU and 23% (n= 796) died. ICU admission was associated with the use of invasive ventilatory support, male gender, presence of comorbidity, and death. For patients with no ICU admission, survival, absence of comorbidity, female gender, use of non-invasive ventilatory support and mild to moderate symptoms of the disease were found. Conclusion: These findings reinforce the need to administer booster doses of the Covid-19 vaccines, but also to strengthen policies to combat chronic noncommunicable diseases in Brazil.
