Trends of epidemiological characteristics of traumatic spinal cord injury in China, 2009–2018

Abstract

Objective We focus on providing the first comprehensive national dataset on the incidence, injury aetiology and mortality of TSCI in China. Methods A multi-stage stratified cluster sampling method was used. We included TSCI cases from all hospitals in three regions, nine provinces and 27 cities in China via search of electronic medical records and retrospectively analysed the characteristics of TSCI in China from 2009 to 2018. We estimated the incidence of TSCI in the total population and subgroups. Results There were 5954 actual cases in 2009, corresponding to a total estimated TSCI incidence of 45.1 cases per million population (95% CI, 44.0–46.3). There were 10,074 actual cases in 2018, corresponding to a total estimated TSCI incidence of 66.5 cases per million population (95% CI, 65.2–67.8) (P < 0.001; annual average percentage change (AAPC), 4.4%). From 2009 to 2018, the incidence of almost all sex/age groups showed an increasing trend over time (P < 0.001; AAPC, 0.7–8.8%). The elderly population (aged 65–74) displayed the highest incidence of TSCI (with an average annual incidence of 127.1 cases per million [95% CI, 119.8–134.3]). Conclusions The TSCI incidence increased significantly from 2009 to 2018. The incidence in the elderly populations was consistently high and continues to increase over time. The mortality of TSCI patients in hospitals is relatively low and continues to decrease each year, but elderly individuals remain at a high risk of hospital death.

Neural Stem Cells Overexpressing Nerve Growth Factor Improve Functional Recovery in Rats Following Spinal Cord Injury via Modulating Microenvironment and Enhancing Endogenous Neurogenesis

“…Spinal cord injury (SCI) is a devastating trauma to the central nervous system (CNS), characterized by severe motor, sensory and autonomic dysfunction. In China, there were 10,074 cases of traumatic SCI in 2018 with a total estimated incidence of 66.5 cases per million in population, and the number is still rising ( Hao et al, 2021 ). However, its treatment is still a major problem in this field, and there is no effective cure currently ( Fan et al, 2018 ).…”

Microglia-Derived Exosomal microRNA-151-3p Enhances Functional Healing After Spinal Cord Injury by Attenuating Neuronal Apoptosis via Regulating the p53/p21/CDK1 Signaling Pathway

“…et al, 2017 ; Khorasanizadeh et al, 2019 ). The incidence of SCI is high, approximately 23.7/million in China ( Hao et al, 2021 ). Over the past decade, a flourishing number of novel strategies have been demonstrated that could promote functional recovery after spinal cord injury in animal models.…”

Comparing the Efficacy and Safety of Cell Transplantation for Spinal Cord Injury: A Systematic Review and Bayesian Network Meta-Analysis

“…In 2016, there were 27.04 million (24.98–30.15 million) SCI cases globally, including 0.93 million (0.78–1.16 million) new cases. Traumatic SCI in China showed an increasing trend from 2009 to 2018, with an estimated 66.5 cases/million population (95% confidence interval, 65.2–67.8) (Hao et al, 2021 ). SCI can impose an enormous physical, emotional, and financial burden on patients, families, and society (Badhiwala et al, 2019 ; Hejrati and Fehlings, 2021 ).…”
