Abstract

CONTEXT:

This systematic review synthesizes what is known about the relationship between public health spending and population health outcomes, as well as the pathways that may explain how outcomes vary with spending. It also discusses the limitations of the existing literature and identifies areas in need of future research.

EVIDENCE ACQUISITION:

Studies included in this review were retrieved through an iterative process, primarily through key word searches in two literature databases (PubMed and JSTOR) conducted in 2013. All retrieved studies underwent initial and secondary screening. Articles were included if they (1) examined the link between spending and outcomes or (2) explored pathways that mediate the relationship between spending and outcomes.

EVIDENCE SYNTHESIS:

Seventeen empirical studies and five literature reviews published between 1985 and 2012 were included in this review. Existing evidence suggests that increases in public health spending are associated with improved population health, at least for some outcomes. However, there is little evidence to suggest that increased spending contributes to meaningful reductions in health disparities. Moreover, the pathways through which greater spending translates into better outcomes are not well understood.

CONCLUSIONS:

Although the complexity of the public health delivery system makes it difficult to demonstrate definitive associations between spending and outcomes, financial investments in public health have the potential to improve community health. Additional research is needed to explore the pathways that mediate this relationship. This research would benefit public health practitioners who need evidence on how to best spend financial resources to achieve better health outcomes.
