Table 3 Research needs and recommendations for future studies

From: Productivity costs from a dengue episode in Asia: a systematic literature review

Key research needs
More data quantifying the productivity losses over the full course of the dengue episode.
More data quantifying the productivity losses associated with presenteeism and lost unpaid work. 
More data quantifying the productivity losses associated with post-acute consequences.
Further investigation and data describing patents’ informal caregivers and their productivity losses.
More data on the health and economic burden of dengue from India and China.
Recommendations for future studies
Clearly state the losses and costs associated with lost paid work and unpaid work.
Clearly report the period of disease that accounted for the productive time lost (i.e. pre-hospitalization, hospitalization and post-hospitalization).
Clearly state and justify the wage source(s) used to value the productivity costs.
Report the average number of informal caregivers per dengue patient and how their time was valued.
Clearly state and justify how children’s productivity losses are quantified and valued monetarily.
