Abstract

Background: Studies on dengue related to the cost of illness and cost of the program are factors to describe the economic burden of dengue, a neglected disease that has global importance in public health. These studies are often used by health managers in optimizing financial resources. A systematic review of studies estimating the cost of dengue was carried out, comparing the costs between the studies and examining the cost drivers regarding the methodological choices.

Methods: This study was done according to the guidelines of the Centre for Reviews and Dissemination (CRD). Several databases were searched: Medline, Virtual Health Library and CRD. Two researchers, working independently, selected the studies and extracted the data. The quality of the methodology of the individual studies was achieved by a checklist of 29 items based on protocols proposed by the British Medical Journal and Consolidated Health Economic Evaluation Reporting Standards. A qualitative and quantitative narrative synthesis was performed.

Results: A literature search yielded 665 publications. Of these, 22 studies are in accordance with previously established inclusion criteria. The cost estimates were compared amongst the studies, highlighting the study design, included population and comparators used (study methodology). The component costs included in the economic evaluation were based on direct and indirect costs, wherein twelve studies included both costs, twelve studies adopted the societal perspective and ten studies used the perspective of the public health service provider, or of a private budget holder.

Conclusion: This study showed that the cost of dengue in 18 countries generated approximately US$ 3.3 billion Purchasing Power Parity (PPP) in 2015. This confirms that the burden of dengue has a great economic impact on countries with common socioeconomic characteristics and similarities in health systems, particularly developing countries, indicating a need for further studies in these countries.
