Document: Objetivo: Describir las caracterÃsticas demográficas y de comorbilidad de los pacientes con COVID-19 fallecidos en hospitales españoles durante el brote pandémico de 2020 y compararlas según si ingresaron o no en una unidad de cuidados intensivos (UCI) antes del fallecimiento. Métodos: Análisis secundario de los pacientes de la cohorte SIESTA (formada por pacientes COVID de 62 hospitales españoles) fallecidos durante la hospitalización. Se recogió su caracterÃsticas demográficas y comorbilidades, individuales y globalmente estimada mediante el Ãndice de Charlson (IC). Se identificaron los factores independientes relacionados con ingreso en UCI, y se realizaron diversos análisis de sensibilidad para contrastar la consistencia de los hallazgos del análisis principal. Resultados: Se incluyeron los 338 pacientes de la cohorte SIESTA fallecidos; de ellos, 77 (22.8%) accedieron a una UCI previamente al fallecimiento. En el análisis multivariable, 3 de las 20 caracterÃsticas basales analizadas se asociaron independientemente con ingreso en UCI de los pacientes fallecidos: demencia (no hubo pacientes fallecidos con demencia que ingresasen en UCI; OR=0, IC95%=no calculable), cáncer activo (OR=0,07, IC95%=0,02-0,21) y edad (<70 años: OR=1, referencia; 70-74 años: OR=0.21, IC95%=0,08-0,54; 75-79 años: OR=0,21, IC95%=0,08-0,54; ≥80 años: OR=0,02, IC95%=0,01-0,05). La probabilidad de ingreso en UCI en los pacientes que fallecieron disminuyó significativamente al aumentar el IC, incluso tras ajustarla por edad (IC 0 puntos: OR=1, referencia; IC 1 punto: OR=0,36, 95%CI=0,16-0,83; IC 2 puntos: OR=0,36, 95%CI=0,16-0,83; ICC >2 puntos: OR=0,09, 95%CI=0,04-0,23). Los análisis de sensibilidad no mostraron diferencias destacables respecto al análisis principal. Conclusiones: El perfil de los pacientes COVID fallecidos sin ingresar en UCI se ajustó a lo observado en la práctica médica habitual antes de la pandemia, y las caracterÃsticas basales que limitaron su ingreso fueron la edad y la carga de comorbilidad global, especialmente la demencia y el cáncer activo. Objective: To describe and compare the demographic characteristics and comorbidities of patients with COVID-19 who died in Spanish hospitals during the 2020 pandemic based on whether they were or were not admitted to an intensive care unit (ICU) prior to death. Methods: We performed a secondary analysis of COVID-19 patients who died during hospitalization included by 62 Spanish emergency departments in the SIESTA cohort. We collected the demographic characteristics and comorbidities, determined both individually and estimated globally by the Charlson index (ChI). Independent factors related to ICU admission were identified and different analyses of sensitivity were performed to contrast the consistency of the findings of the principal analysis. Results: We included the 338 patients from the SIESTA cohort that died during hospitalization. Of these, 77 (22.8%) were admitted to an ICU before dying. After multivariate adjustment, 3 out of the 20 basal characteristics analyzed in the present study were independently associated with ICU admission: dementia (no patients with dementia who died were admitted to the ICU: OR=0, 95%CI=not calculable), active cancer (OR=0.07; 95%CI=0.02-0.21) and age (<70 years: OR=1, reference; 70-74 years: OR=0.21; 95%CI=0.08-0.54; 75-79 years: OR=0.21; 95%CI=0.08-0.54; ≥80 years: OR=0.02; 95%CI=0.01-0.05). The probability of ICU admission significantly increased in parallel to the ChI, even after adjustment for age (ChI 0 points: OR=0, reference; ChI 1 point: OR=0.36; 95%CI=0.16-0.83; ChI 2 points: OR=0.36; 95%CI=0.16-0.83; ChI >2 points: OR=0.09; 95%CI=0.04-0.23). The sensitivity analyses showed no gross differences compared to the principal analysis-. Conclusions: The profile of COVID-19 patients who died without ICU admission is similar to that observed in the usual medical practice before the pandemic. The basal characteristics limiting their admission were age and global burden due to comorbidity, especially dementia and active cancer.
