Long-term trends and risk factors of tracheostomy and decannulation in patients with cervical spinal cord Injury

Abstract Study design： Retrospective study. Objectives： To investigate the risk factors of tracheostomy and decannulation after cervical spinal cord injury (CSCI) and their epidemiological changes over the past 8 years in Beijing Bo’ai Hospital, China Rehabilitation Research Center (CRRC), China. Setting： Beijing Bo’ai Hospital, CRRC. Methods： We reviewed 8 years of patient data (2013.1.1 to 2020.12.31) at CRRC, focusing on those hospitalized and diagnosed with CSCI. We analyzed changes in demographic and clinical data’s trends. Logistic regression analysis was used to determine factors impacting tracheostomy and decannulation. Results： Finally, 1641 CSCI patients met the inclusion criteria. Over the past 8 years, the proportion of tracheostomized patients with CSCI was 16.3%, and the proportion of successfully decannulated was 77.9%.We found that Traumatic (OR=1.8, 95%CI= 1.06,3.22;p=0.046),Motor level of injury (C5-C8) (OR=0.32, 95%CI= -1.91,-0.34;p=0.005), AIS=A/B/C (OR=22.7/11.1/4.2, 95%CI= 12.16,42.26/5.74,21.56/2.23,7.89;p<0.001/ p<0.001/ p<0.001), Age>56 (OR=1.6, 95%CI= 1.04,2.32;p=0.031) were the risk factors for tracheostomy. By analyzing the risk factors of decannulation in tracheostomized patients with TCSCI through multivariable logistic regression, statistically significant differences were found in age＞45(OR=4.1, 95%CI= 1.44,11.81; p =0.008),complete injury(OR=2.7, 95%CI= 1.26,5.95; p =0.011), facet dislocation (OR=2.8, 95%CI= 1.13,7.07; p =0.027). Conclusions ： Recent years have witnessed shifts in the epidemiological characteristics of CSCI. Identifying the factors influencing tracheostomy and decannulation in CSCI can aid in improving patient prognosis.
