A total of 6 studies investigated SCI cost of illness from a Canadian health care system perspective (Dryden et al. 2005, Bradbury et al. 2008, Munce et al. 2013, Radhakrishna et al. 2014, White et al. 2017, Chan et al. 2018). Dryden and colleagues (2005) examined a cohort of individuals from Alberta. Costs were stratified by level of injury (tetraplegia versus thoracic versus lumbar) and whether it was complete or incomplete. Results were further stratified for first year after injury and years 2-6. Inpatient hospital, physician, home-care and long-term care costs were included in their analysis. Since this study had a non-SCI comparator both incidence and attributable costs were calculated. Administrative data was used to identify cohort and extract costing information; thus the study is limited by the quality of the administrative data. Results were calculated from 2009 costs and are shown in tables 8-10.
