Food Insecurity Adds $53 Billion to US Medical Bills Annually

Food insecurity contributes an estimated $53 billion to the United States' annual medical bill, according to a 2019 study. Despite this significant financial impact and its direct correlation with adverse health outcomes, most healthcare providers continue to document food insecurity as a note in patient charts rather than treating it as a vital sign. This approach overlooks its critical role in patient health, leading to higher rates of chronic disease, impaired immune response, and slower tissue repair among affected individuals. These complications result in increased emergency department visits, inpatient admissions, and prolonged hospital stays.

The prevalence of food insecurity in the U.S. has risen since 2020, with approximately 1 in 7 households, or nearly 48 million people, experiencing it. Individuals facing food insecurity often present with a sicker baseline upon entering surgery or hospitalization. For trauma patients, food insecurity is associated with a threefold increase in post-operative complications and a median hospital stay more than double that of other patients. For seniors, the impact is equivalent to aging an additional 14 years in terms of limitations on daily activities, and their healthcare costs can exceed those of patients without food insecurity by more than double.

Food insecurity shares characteristics with vital signs, being predictive, measurable, and treatable, and it is tightly linked to patient outcomes, arguably more so than some currently tracked vital signs. The infrastructure for monitoring and acting on traditional vital signs has been established over decades. In contrast, food insecurity is often treated as an isolated issue, disconnected from the primary clinical record. If a condition were found to double a patient's risk of poor health and increase emergency department visits and hospital days, it would likely be integrated into all clinical workflows.

Hospitals are increasingly equipped to screen for food insecurity and identify it among patients. However, a significant gap exists between the care provided within hospitals and the subsequent care patients receive at home or at their next point of treatment. The current system often fails to bridge this gap effectively, leaving many patients without the necessary support to address their food insecurity post-discharge.
