ABSTRACT
OBJECTIVE: To determine the probability of hospitalization for chronic degenerative disease in patients with COVID-19. MATERIALS AND METHODS: A retrospective cohort in patients with COVID-19, confirmed by RT-PCR. Two study groups were integrated, the exposed group made up of 3 subgroups, exclusively diabetes mellitus, exclusively arterial hypertension and exclusively obesity;the unexposed group was the one in which any chronic comorbidity was ruled out. Relative risk, multiple logistic regression and probability calculation of the event (hospitalization) were used. RESULT(S): The relative risk for hospitalization in diabetes was of 3.59 (95%CI;2.44-5.29), 3.20 (95%CI;2.10-4.87) in hypertension and 2.56 (95%CI;1.72-3.81) in obesity. The multiple regression equation was y = -1358 + 2388 (diabetes mellitus) + 2005 (systemic arterial hypertension) + 1458 (obesity). The probability of hospitalization when there was no chronic disease was of 20.6%, when there was a chronic disease the probability fluctuated between 52.5% and 73.5%, when there were two chronic diseases it varied from 89.1% to 95.4%, and when there were three diseases the probability of hospitalization was of 98.9%. CONCLUSION(S): In the context of the probability of hospitalization when there is a chronic degenerative disease or it is absent, the research shows the difference in these two scenarios, as revealed by the more than 70 percentage points identified in the extreme scenarios, a condition that, led to the clinical field, reaffirms the presence of chronic degenerative disease as a risk factor for hospitalization.Copyright © 2023 Comunicaciones Cientificas Mexicanas S.A. de C.V..
