Abstract
Objective: To identify the factors associated with the hospitalization of COVID-19 patients in an intensive care unit. Materials and methods: An observational, cross-sectional and analytical study. The sample consisted of COVID-19 patients treated at the Clínica Good Hope from April to June 2020. The variables were: outcome (place of hospitalization: intensive care unit or internal medicine service) and exposure (age, sex, disease period, comorbidities and laboratory tests such as levels of lactate dehydrogenase, ferritin, D-dimer and C-reactive protein). A descriptive, bivariate analysis and a simple GLM Poisson regression were performed to calculate the odds ratio (OR). Results: Seventy-six (76) patients were evaluated (60 in the internal medicine service and 16 in the intensive care unit). The mean age was 52 years and males prevailed (81.6 %). Elevated serum levels of lactate dehydrogenase, D-dimer and C-reactive protein were associated with a 0.02 % more chance of admission to the intensive care unit at the time of hospitalization, which is statistically significant (OR: 1.002, 95 % CI: 1.001 - 1.003; OR: 1.05, 95 % CI: 1.01 - 1.10; and OR: 1.06, 95 % CI: 1.02 - 1.09). Conclusions: The levels of lactate dehydrogenase, D-dimer and C-reactive protein are associated with the admission to an intensive care unit during hospitalization and could reflect the severity of the disease.

Summary
Objetivo: Identificar los factores asociados a la hospitalización de los pacientes con COVID-19 en una unidad de cuidados intensivos. Las variables consideradas fueron las siguientes: variable resultado (el lugar de hospitalización: unidad de cuidados intensivos o servicio de medicina) y variable exposición (edad, sexo, tiempo de enfermedad, comorbilidades y exámenes de laboratorio como deshidrogenasa láctica, ferritina, dímero D, proteína C-reactiva). Los niveles séricos elevados de deshidrogenasa láctica, dímero D y proteína C-reactiva se asociaron con el aumento de la probabilidad de ingreso en la unidad de cuidados intensivos al momento de la hospitalización en 0,02 %, lo que es estadísticamente significativo (RP: 1,002; IC95% 1,0011,003; RP: 1,05; IC95% 1,01-1,10 y RP: 1,06; IC95% 1,02-1,09). Conclusiones: Los niveles de deshidrogenasa láctica, proteína C-reactiva y dímero D están asociados con el ingreso a una unidad de cuidados intensivos durante la hospitalización y podrían reflejar la severidad de la enfermedad.
