Costs of dementia in low-and-middle income countries: a systematic review

Abstract : Objective: To review studies conducted on the costs of dementia in low- and middle-income countries (LMICs), describe their methodology and summarize costs estimates. Methods: We conducted a systematic review, searching in bibliographic databases in health, economics and social sciences, and main grey literature resources. Publications were evaluated by two independent investigators, conflict discussed, and the final decision taken by a third investigator. We included all studies presenting costs of any aspect of dementia care. Results: Overall, 6,843 title and abstract, then 74 full texts articles evaluated. Finally, 15 single studies were included. Those were from only 9 out of the 156 LMICs: China (6); Brazil (2); and one from Argentina, Colombia, Iran, Peru, Romania, Thailand and Turkey. No study was from Africa. Studies focused mainly on Alzheimer’s disease. Studies investigated all three categories of cost-of-illness i.e., medical, social and informal care costs, but items, data collection and definitions in each category were highly variable. Dementia costs tend to increase with the severity of the disease with greater medical costs in the mild stage and higher social and informal care costs in the moderate and severe stages. Costs estimates varied widely: from $327.4 to $1,266.3 for annual medical costs, from $112.4 to $5,575.0 for social costs; and costs from $324.0 to $10,031.1 for informal care. Overall, dementia care cost up to $19,101 per year for a single patient, usually at the charge of families. Conclusion: Limited studies have been conducted on dementia costs in LMICs, with none so far in Africa. It appears urgent to provide accurate evidence of the disease burden in the region to guide public health policies.
