Ensuring financial protection (FP) against health expenditures is a key component of Sustainable Development Goal (SDG) 3.8, which aims to achieve Universal Health Coverage (UHC). While the proportion of households with catastrophic health expenditures exceeding a proportion of their total income or consumption has been adopted as the official SDG indicator, other approaches exist and it is unclear how useful the official indicator is in tracking progress toward the FP sub-target across countries and across time. This paper evaluates the usefulness of the official SDG indicator to measure FP using the RACER framework and discusses how alternative indicators may improve upon the limitations of the official SDG indicator for global monitoring purposes. We find that while all FP indicators have some disadvantages, the official SDG indicator has some properties that severely limit its usefulness for global monitoring purposes. We recommend more research to understand how alternative indicators may enhance global monitoring, as well as improvements to the quality and quantity of underlying data to construct FP indicators in order to improve efforts to monitor progress toward UHC.
