Just like a well-organized travel website that helps you plan your vacation, scientists have developed a website to guide clinicians in making decisions for patients with prolonged disorder of consciousness (pDOC). The website features a nomogram, which is like an interactive map that predicts patient survival at different time intervals. To create the nomogram, researchers analyzed data from 381 patients and identified four key factors that significantly affected patient outcomes. These factors include age, Glasgow coma scale (GCS) score, serum albumin level, and computed tomography (CT) midline shift. By inputting these variables into the website, clinicians can obtain personalized predictions for survival at 16, 32, and 48 months. The nomogram has been rigorously tested and shown to have good discriminative power, calibration, and clinical efficacy. It’s like having a trusted travel advisor by your side to help you make informed decisions about patient care.

BackgroundThis study aimed to develop and validate a nomogram and present it on a website to be used to predict the overall survival at 16, 32, and 48 months in patients with prolonged disorder of consciousness (pDOC).MethodsWe retrospectively analyzed the data of 381 patients with pDOC at two centers. The data were randomly divided into training and validation sets using a ratio of 6:4. On the training set, Cox proportional hazard analyses were used to identify the predictive variables. In the training set, two models were screened by COX regression analysis, and based on clinical evidence, model 2 was eventually selected in the nomogram after comparing the receiver operating characteristic (ROC) of the two models. In the training and validation sets, ROC curves, calibration curves, and decision curve analysis (DCA) curves were utilized to measure discrimination, calibration, and clinical efficacy, respectively.ResultsThe final model included age, Glasgow coma scale (GCS) score, serum albumin level, and computed tomography (CT) midline shift, all of which had a significant effect on survival after DOCs. For the 16-, 32-, and 48-month survival on the training set, the model had good discriminative power, with areas under the curve (AUCs) of 0.791, 0.760, and 0.886, respectively. For the validation set, the AUCs for the 16-, 32-, and 48-month survival predictions were 0.806, 0.789, and 0.867, respectively. Model performance was good for both the training and validation sets according to calibration plots and DCA.ConclusionWe developed an accurate, efficient nomogram, and a corresponding website based on four correlated factors to help clinicians improve their assessment of patient outcomes and help personalize the treatment process and clinical decisions.
