Abstract
La pandemia de COVID-19 ha generado millones de infectados y cientos de miles de muertes, debido a la alta transmisibilidad del virus. La estratificación del riesgo es crucial, ya que la enfermedad puede variar desde asintomática hasta casos graves con fallo multiorgánico y muerte. Factores como la edad avanzada y enfermedades crónicas aumentan la gravedad y el riesgo de malos resultados. Las imágenes de tórax, como la radiografía (RT) y la tomografía computarizada (TC), son valiosas para el diagnóstico, aunque la elección depende de factores locales y recursos disponibles. La puntuación RALE en las radiografías de tórax se usa como indicador pronóstico; puntajes bajos (<5) sugieren menor probabilidad de resultados graves, mientras que puntajes altos (≥5) aumentan la probabilidad de complicaciones graves o resultados desfavorables.
Varios estudios analizaron la relación entre la puntuación RALE en radiografías de tórax y la gravedad o pronóstico del COVID-19. Mientras mayor sea la puntuación RALE, mayor es la probabilidad de tener diagnósticos graves o peores resultados en pacientes con COVID-19. La presencia de opacidades pulmonares en estas imágenes se relaciona con un aumento del riesgo de mortalidad, y una puntuación RALE baja se vincula con un mejor pronóstico y menor riesgo de complicaciones. Esto sugiere que la puntuación RALE en radiografías de tórax puede ser útil como herramienta predictiva en la evaluación de pacientes con COVID-19.
El presente estudio tiene como finalidad dar a conocer cuan sensible es el uso de la escala RALE Modificada (Radiographic Assessment of Lung Edema) como factor predictor de mortalidad en pacientes hospitalizados con diagnóstico de neumonía por COVID-19, incluyendo no solo factores imagenológicos sino también clínicos.
The COVID-19 pandemic has resulted in millions of infections and hundreds of thousands of deaths due to the high transmissibility of the virus. Risk stratification is crucial as the disease ranges from asymptomatic cases to severe ones with multi-organ failure and death. Factors such as advanced age and chronic diseases increase severity and the risk of poor outcomes. Chest imaging, including X-rays (RT) and computed tomography (CT), is valuable for diagnosis, although the choice depends on local factors and available resources. The RALE score in chest X-rays is used as a prognostic indicator; low scores (<5) suggest a lower likelihood of severe outcomes, while high scores (≥5) increase the likelihood of severe complications or unfavorable outcomes. Several studies have analyzed the relationship between RALE scores in chest X-rays and the severity or prognosis of COVID-19. The higher the RALE score, the greater the probability of severe diagnoses or worse outcomes in COVID-19 patients. The presence of lung opacities in these images is associated with an increased risk of mortality, while a low RALE score is linked to a better prognosis and lower risk of complications. This suggests that RALE scoring in chest X-rays can be useful as a predictive tool in evaluating COVID-19 patients. This study aims to demonstrate how sensitive the use of the Modified RALE scale (Radiographic Assessment of Lung Edema) is as a predictor of mortality in hospitalized patients diagnosed with COVID-19 pneumonia, encompassing not only imaging but also clinical factors.
