Justificación y objetivos: La COVID-19 es una enfermedad potencialmente mortal. Reconocer las características de la enfermedad y sus principales complicaciones en esta población ayudará a futuras intervenciones, atención y gestión de los servicios de salud, ya que las diversidades territoriales y poblacionales influyen directamente en los resultados de salud. El objetivo principal de este estudio es describir las características clínicas, los resultados y los factores asociados a la mortalidad de los pacientes con COVID-19 ingresados en la unidad de cuidados intensivos de un hospital público y de tercer nivel. Métodos: Estudio de cohorte, realizado del 1 de marzo al 30 de septiembre de 2020. Se realizó regresión de Poisson para investigar variables en la presentación hospitalaria como potenciales factores de riesgo para la mortalidad intrahospitalaria. Resultados: De los 283 pacientes elegibles en este estudio, el 41,7% (n=118) tuvo mortalidad hospitalaria. Los desenlaces más comunes fueron síndrome de dificultad respiratoria aguda, infección nosocomial y shock séptico. Los factores independientemente asociados a mayor riesgo de muerte fueron edad mayor de 51 años (RR=1,7, IC95%=1,0-2,8), especialmente mayores de 70 años (RR=2,9, IC95%=1,7-2,8), tabaquismo actual (RR=1,8, IC95%=1,1-2,9), necesidad de inotrópico (RR=1,4, IC95%=1,0-2,0) y potasio mayor que 5,0 mEq/l (RR=1,3, IC95%=1,0-1,7). Conclusión: La mortalidad estuvo asociada a la edad avanzada, tabaquismo actual, uso de inotrópico y potasio mayor a 5,0 en la admisión hospitalaria.
