To investigate the direct healthcare costs of spinal disorders in Brazil, over 2016.
Prevalence-based cost-of-illness study, top-down approach and public healthcare system's perspective. International Classification of Diseases codes related to spinal disorders were included. The following costs were obtained: (1) hospitalization; medical professional service costs; intensive care unit costs; companion daily stay; (2) outpatient (services/procedures). Data were analyzed descriptively and costs presented in US$.
The healthcare system spent US$ 71.4 million and inpatient care represented 58%. The number of inpatient days was 250,426 and there were 36,654 hospital admissions (dorsalgia and disc disorders representing 70%). A total of 100,000 magnetic resonance and 80,000 computerized tomography scans was adopted. Men had more inpatient days (138,215) than women (112,211). Overall, the inpatient/outpatient cost ratio was twice as high for men.
We demonstrated that the direct costs of spinal disorders in Brazil in 2016 were high. We also found a substantial amount of financial resources spent on diagnostic imaging. This is relevant, as the routine use of diagnostic imaging for back pain is discouraged in international guidelines.
