Evidence Links Increases In Public Health Spending To Declines In Preventable Deaths

TLDR

Public health programs aim to prevent disease and injury, yet policymakers have limited evidence to assess their value, spend less than 5 % of US health budgets, and increased funding alone is unlikely to yield lasting gains without improved practices. The study investigates whether 13‑year changes in local public health spending affect community mortality from preventable causes such as infant deaths, cardiovascular disease, diabetes, and cancer. The authors analyzed 13‑year trends in local public health spending and corresponding community mortality rates for preventable causes such as infant mortality, cardiovascular disease, diabetes, and cancer. Each 10 % increase in local public health spending was associated with a 1.1–6.9 % decline in preventable mortality, indicating that higher investments yield measurable health gains, particularly in low‑resource communities.

Abstract

Public health encompasses a broad array of programs designed to prevent the occurrence of disease and injury within communities. But policy makers have little evidence to draw on when determining the value of investments in these program activities, which currently account for less than 5 percent of US health spending. We examine whether changes in spending by local public health agencies over a thirteen-year period contributed to changes in rates of community mortality from preventable causes of death, including infant mortality and deaths due to cardiovascular disease, diabetes, and cancer. We found that mortality rates fell between 1.1 percent and 6.9 percent for each 10 percent increase in local public health spending. These results suggest that increased public health investments can produce measurable improvements in health, especially in low-resource communities. However, more money by itself is unlikely to generate significant and sustainable health gains; improvements in public health practices are needed as well.
