Background:
Intubation rates up to 33% have been found in patients diagnosed with COVID-19. Some cohorts have reported the presence of dyspnea in 84.1% of intubated patients, being this the only symptom associated with intubation. Oxygen saturation < 90% and increased respiratory rate have also been described as predictors of intubation.
Objective:
To analyze the risk factors associated with intubation in patients hospitalized for COVID-19 at their admission.
Material And Methods:
An observational, retrospective, analytical, cross-sectional study was carried out. The universe of study consisted of patients over 18 years of age hospitalized due to a diagnosis of SARS-CoV-2 virus infection from April 1, 2020 to April 31, 2021 in the Hospital de Especialidades (Specialties Hospital) "Dr. Bernardo Sepúlveda Gutiérrez" at the National Medical Center.
Results:
The mean age of intubated patients was 59.17 years (95% confidence interval [95% CI] -9.994 to -3.299, p < 0.001). Overall, 76.7% (230) of patients had a history of one or more preexisting comorbidities, including hypertension in 42.3% (127), obesity in 36.7% (110), and diabetes mellitus in 34.3% (103).
Conclusions:
The main clinical characteristics of patients hospitalized for COVID-19 in our center who required intubation are very similar to those observed in different centers, including male sex, age over 50 years and obesity, which were the most common.
