Abstract: Objective: To evaluate the predictive validity of the screening scale for risk of accidental aspiration in postoperative evaluation of patients with neurologic tumors. Methods: Using the prospective analysis method, 168 patients underwent craniotomy enrolled in the study were evaluated by the screening scale for risk of accidental aspiration. The actual incidence of aspiration, the best predicted critical value, the AUC area under the receiver operating characteristic(ROC) curve, the sensitivity, specificity, positive prediction value, and negative predictive value of the screening scale were calculated. Results: The actual incidence of accidental inhalation was 21.4%; The AUC area under the ROC curve was 0.806(95 % CI = 0.737 to 0.876, P<0.001); The best predicted threshold of the scale was 6 points, and the Youdeng index reached a maximum of 0.452. At this time, the sensitivity and specificity were 0.861 and 0.591, and the positive and negative predictions were 0.360 and 0.940. Conclusion: The screening scale for risk of accidental aspiration has a good predictive effect and can be used as a risk assessment tool for patients with neurologic tumors after surgery.
