Study design:A retrospective cohort study.Objectives:To review demographic trends in traumatic spinal cord injury (TSCI) and non-traumatic spinal cord injury (NTSCI).Setting:The Queen Elizabeth National Spinal Injuries Unit (QENSIU), sole provider of treatment for TSCI in Scotland; a devolved region of the UK National Health Service.Methods:A retrospective review of the QENSIU database was performed between 1994 and 2013. This database includes demographic and clinical data from all new TSCI patients in Scotland, as well as patients with severe NTSCI.Results:Over this 20-year period there were 1638 new cases of TSCI in Scotland; 75.2% occurring in males. TSCI incidence increased non-significantly (13.3 per million population to 17.0), while there were significant increases in mean age at time of TSCI (44.1–52.6 years), the proportion of TSCIs caused by falls (41–60%), the proportion of TSCIs resulting in an American Spinal Injury Association Impairment Scale score of C and D on admission (19.7–28.6% and 34.5–39.5%, respectively) and the proportion of cervical TSCIs (58.4–66.3%). The increase in cervical TSCI was specifically due to an increase in C1–C4 lesions (21.7–31.2%). NTSCI patients (n=292) were 5 years older at injury, more likely to be female (68.1% male) and had a range of diagnoses.Conclusion:This study supports the suggestion that demographic profiles in SCI are subject to change. In this population, of particular concern is the increasing number of older patients and those with high level tetraplegia, due to their increased care needs. Prevention programmes, treatment pathways and service provision need to be adjusted for optimum impact, improved outcome and long-term care for their target population.

This study provides benchmark data on the use of imaging for back pain in an Australian ED, an area which has been largely unexplored. The rate of imaging in the ED was higher than previously reported in a General Practice setting. Consistent with guidelines, patients older than 70 were more than twice as likely to receive imaging compared to younger patients. It was beyond the scope of the current study to determine whether these images were clinically indicated and further research is required to determine if initiatives to reduce imaging in this population are warranted.
