Resource utilisation and cost of ankylosing spondylitis in Brazil (original) (raw)

Clinical and experimental rheumatology

The present study describes resource utilisation in patients with ankylosing spondylitis (AS) treated at a tertiary public health facility over a one-year period. It also investigates the direct and indirect costs for society associated with the treatment of AS. Ninety AS patients were selected consecutively, and data was analysed retrospectively for one year. Resource utilisation was evaluated through systematic interviews with all patients. Demographic, socioeconomic, and clinical variables were recorded, and questionnaires evaluating quality of life, function, and disease activity were also applied (ASQoL, SF-36, HAQ-S, BASFI, and BASDAI). Estimates of indirect costs were performed using the human-capital approach based on the society perspective. Most of the patients were men (79%), with a mean age and disease duration of 40 and 16 years, respectively. The mean HAQ-S, BASFI and BASDAI scores were 1, 5, and 4, respectively. The mean ASQoL score for the sample was 8, and the mean ...
