Abstract

Nasogastric tube feeding is often used to provide optimal nutrition and hydration in patients with aspiration pneumonia. However, evidence regarding radiologic indicators for successful nasogastric tube weaning is lacking. We investigated whether thoracic skeletal muscle assessment can be useful for predicting successful weaning from nasogastric tube feeding in patients with aspiration pneumonia. This longitudinal, observational study included subjects with aspiration pneumonia who underwent a videofluoroscopic swallowing study (VFSS) and chest computed tomography (CT) in Boramae Medical Center, from January 2012 to December 2019. We estimated the area under the receiver operating characteristics curve (AUC) to evaluate the predictive performance of skeletal muscle and visceral fat parameters and VFSS results for successful weaning from nasogastric tube feeding. A board-certified radiologist measured muscle and fat areas. Muscle and fat volumes were segmented and measured using an externally validated convolutional neural network model. Among the 146 included patients, nasogastric tube feeding was successfully transitioned to oral feeding in 46.6%. After adjusting for covariables related to successful weaning, skeletal muscle areas, indices, and volume indices were positively associated with successful nasogastric tube weaning. Although VFSS results and skeletal muscle parameters alone showed suboptimal performance for predicting successful weaning, a prediction model combining skeletal muscle index at the T4 level and VFSS results improved the prediction performance to an acceptable level (AUC ≥ 0.7). Skeletal muscle index measured at the T4 level may be a useful supplementary indicator for predicting successful weaning from nasogastric tube feeding in patients with aspiration pneumonia.
