Factors influencing swallowing outcome in prolonged disorders of consciousness patients with tracheostomy
Objective:To explore the factors influencing swallowing outcome in patients with disorders of con-sciousness patients with tracheostomy.Methods:This retrospective study collected clinical data of disorder of con-sciousness patients with tracheostomy.The data included demographic characteristics at admission,CRS-R scores,GCS scores,modified Evans blue dye test,duration of tracheostomy and Functional Oral Intake Scale(FOIS)at ad-mission.Follow-up was conducted at 1 year to collect tracheostomy decannulation status,GCS scores and FOIS scores.A total of 141 patients with disorder of consciousness were included in this study and the data of 138 partici-pants were included in the final analysis.Based on the FOIS scores at one year of follow-up,the patients were divid-ed into two groups:poor swallowing function group(FOIS levels 1-3)with 71 cases and good swallowing function group(FOIS levels 4-7)with 70 cases.Logistic regression analysis was employed to the correlation between various factors and the recovery of swallowing function.Results:The decannulation rate was higher in the good swallowing function group than in the poor swallowing function group(P＜0.01),and the proportion of patients with a GCS score ≥8 was higher in the good swallowing function group than the poor swallowing function group(P＜0.05).Logistic regression analysis revealed that dye test results,tracheostomy decannulation within 1 year,and GCS scores at 1 year significantly influenced the recovery of swallowing function recovery at 1 year(P＜0.05,0.01).Conclusion:Factors associated with better swallowing function recovery in disorder of consciousness patients with tracheostomy due to severe brain injury include initial modified dye test results,decannulation within 1 year,and GCS scores at 1 year.
