Introduction/Objectives:
This rapid evidence assessment (REA) was conducted to assess the burden of weight-bearing joint osteoarthritis in the developing countries of Africa and the Middle East.
Methods:
Our REA methodology used a standardized search strategy to identify observational studies, published between January 1, 2010, and April 23, 2020, reporting on outcomes pertaining to the epidemiology and humanistic or economic burden of weight-bearing osteoarthritis. Relevant data from the included studies were used for qualitative analysis.
Results:
Among the 20 publications reporting on knee osteoarthritis in 10 countries in Africa and the Middle East, 2 also reported on hip, and 1 on foot osteoarthritis. Prevalence of symptomatic/radiographic knee OA was 9-14% among rheumatology outpatients and 31-34% among those with mixed etiology osteoarthritis. Prevalence of knee OA diagnosed by magnetic resonance imaging was 70% among patients ≥40 years of age attending a hospital in Saudi Arabia. Quality-of-life outcomes were reported in 16 publications and suggested a substantial humanistic burden of osteoarthritis, including worse pain, function, and quality of life, and more depression; comparisons between studies were hampered by the variety of tools and scoring scales used, however. No studies reported on economic outcomes.
Conclusion:
This REA indicates a substantial burden of osteoarthritis in weight-bearing joints in Africa and the Middle East, consistent with publications from other regions of the world.
