OP0110 Performance of a telephone questionnaire administered by lay people for case detection of rheumatoid arthritis and spondylarthropathy

Abstract

Conclusion In this study patients with a diagnosis of RA were 70% more likely to die and 30-40% more likely to suffer an acute major thromboembolic event compared with patients with a diagnosis of OA but not RA. In addition, patients with a diagnosis of RA were 60% more likely to die, and 30-50% more likely to suffer an acute major thromboembolic event compared with patients with no arthritis diagnosis.

The Prevalence of Rheumatoid Arthritis in Chile: A Nationwide Study Performed as Part of the National Health Survey

“…Prevalence studies of RA throughout the world have shown frequencies between 0.3% and 1% [9][10][11][12][13][14][15][16][17][18] . Genetic and environmental backgrounds influence RA development and therefore it is important to have local data.…”

Evaluation of 2 Screening Strategies for Early Identification of Patients with Axial Spondyloarthritis in Primary Care

“…AS -the prototype disease of the SpA group -has an estimated prevalence of about 0.5% 6,7 , whereas the estimated prevalence for the whole group of SpA is about 1.5% 6,7 . Although the prevalence of SpA in the general population is high and is comparable with that of rheumatoid arthritis 7,8,9 , there is a major problem with the early diagnosis of axial SpA. The delay between first symptoms and a final diagnosis has been reported in different surveys to be between 5 and 10 years in developed countries 10,11,12 , often associated with a long history of futile diagnostic efforts.…”
