Background/Aims: Musculoskeletal (MSK) disorders are one of the major causes of non-traumatic disability within the global burden of disease. A 2010 Global Burden of Disease study reported that MSK diseases account for 20% of all Years Lived with Disability (YLDs) in low/middle income countries. Significantly contributing to this MSK burden is arthritis. In Tanzania, a lack of data exists on the prevalence, quality of life, economic and societal impact of arthritis. We aim to estimate the health, economic and societal burden of arthritis in Tanzania. Methods: A community-based cross-sectional survey was undertaken between January 2021 to Sept 2021 in the Kilimanjaro region of Tanzania working in partnership with the Kilimanjaro Christian Research Institute and Kilimanjaro Christian Medical Centre. Clinical screening tools, including the Gait Arms Legs Spine (GALS) and Regional Examination of the Musculoskeletal system (REMS) were used to screen people with MSK diseases and possible arthritis through a tiered system approach. Economic and quality of life questionnaires were used for a representative sample of all residents (aged over 5 years old) in selected households. Ethiopia and Zimbabwe tariffs were used for the EuroQol EQ-5D. Resource use captured out-of-pocket costs, healthcare costs, absenteeism, presenteeism & work productivity loss. Regression based analysis were undertaken to estimate differences in utility scores and resources use / costs between those presenting as REMS+/- and GALS+/-. Other explanatory variables in the model included age, occupation, marital status, gender, religion, tribe, education. Results: Preliminary results on data collected to-date show that for all QoL dimensions those with a positive diagnosis had lower utility scores. Whilst the population norms are in line with utility values for that age group from other countries (30-40 years, ∼0.9 utility), those presenting with a positive diagnosis had a significant reduction in utility of ∼0.12 to 0.15 depending on what country tariff was used. A higher proportion of participants in GALS/REMS +ve groups experienced work loss (6 x more likely) and had visited healthcare facilities/hospitalisation (2.5 x more likely) compared to GALS/REMS -ve. Health-related costs reported by household financial respondents did not show a significant statistical difference albeit a likely economically significant difference (Tanzanian Shillings 13,535 vs 6,683, p = 0.05), when adjusted for age and gender. Conclusion: This is the first study to estimate burden and prevalence estimates of MSK in Tanzania using valid screening tools along with estimates of preference-based quality of life, disability impacts and quantification of the economic impacts of MSK. This study quantifies the significant burden of rheumatological conditions both in terms of health and poverty. The results will be used to guide clinical health practices, intervention design, service provision, and health promotion and awareness activities both at KCMC institutional level, Kilimanjaro region and national level.
