Hospital Ads Increase ED Visits, Medicare Spending: Penn Study

Why It Matters

The findings suggest taxpayer‑funded advertising may inflate Medicare utilization, prompting policymakers to reassess how public money influences health‑care demand.

Key Takeaways

• 10% ad rise adds nine admissions per 100k beneficiaries.
• Advertising elasticity estimated at 6% per 100 impressions.
• Study uses Medicare claims and Nielsen ad data (2015‑16).
• Impact unclear if patients shift or add new visits.
• Policymakers may need to monitor ad‑driven utilization.

Pulse Analysis

Hospital advertising has surged in recent years, becoming the second‑largest category of healthcare marketing spend behind pharmaceuticals. As hospitals vie for patients in competitive markets, they increasingly deploy TV, radio and digital spots to promote services and brand awareness. A new University of Pennsylvania study leverages traditional Medicare claims linked with Nielsen ad‑impression data from January 2015 through November 2016, a period that includes an election cycle that temporarily suppressed health‑care ads. By isolating variations in ad volume across regional markets, the researchers quantify how promotional activity translates into patient behavior.

The analysis finds that a 10 percent rise in hospital ad impressions—roughly 150 additional spots—produces nine extra admissions per 100,000 Medicare beneficiaries, implying an advertising elasticity of about six percent. In practical terms, every hundred extra impressions generate six additional emergency‑department visits. While the study cannot definitively separate new demand from patients diverted from rival facilities, the aggregate increase in utilization directly lifts Medicare expenditures, creating a feedback loop where public funds finance ads that then spur further spending.

These findings raise policy questions about the appropriateness of taxpayer‑funded advertising that may encourage low‑value care. Regulators could consider transparency rules requiring hospitals to disclose ad spend linked to Medicare billing, or incentive structures that reward cost‑effective outreach rather than volume growth. For health‑system executives, the research underscores the need to balance brand promotion with stewardship of public resources, especially as value‑based payment models gain traction. Future work should isolate the marginal health outcomes of ad‑driven visits to determine whether the added utilization improves or merely inflates costs.
