Tourists More Likely to Undergo Unnecessary Imaging in the ED

Why It Matters

The overuse of imaging on non‑resident patients inflates healthcare costs, strains radiology resources, and raises radiation exposure concerns, prompting hospitals to rethink staffing and protocols in tourist‑heavy regions.

Key Takeaways

• Tourists comprised 18% of ED visits in Trentino region
• They accounted for 20% of all imaging exams performed
• Non‑residents faced 32% higher odds of excess imaging
• Red‑triage tourists received four additional scans on average
• Language barriers drive clinicians toward more comprehensive radiology

Pulse Analysis

The surge of visitors to popular destinations places unique pressure on emergency departments, a reality highlighted by a new study published in Emergency Radiology. Researchers examined 740,000 ED encounters in Italy’s Trentino province from 2018‑2024, finding that tourists—who made up roughly 18% of visits—were responsible for about 20% of all radiologic examinations. This disproportional use of imaging suggests that non‑resident patients trigger a different diagnostic pathway, prompting hospitals to allocate resources beyond what local demand alone would dictate. These data also raise concerns about potential overuse of costly imaging modalities in health systems already strained by seasonal demand.

Statistical analysis revealed a 32% increase in the odds that a tourist would receive excessive imaging, with red‑triage cases averaging four extra scans per encounter. Skeletal studies were especially prevalent, reflecting the higher incidence of trauma among vacationers engaging in outdoor activities. Researchers attribute the pattern to limited clinical histories, language barriers, and heightened uncertainty, which collectively push clinicians toward a more defensive imaging strategy. Younger male tourists, in particular, showed a marked propensity for trauma‑related scans. The excess imaging not only inflates costs but also increases patient exposure to ionizing radiation, underscoring the need for judicious use.

The findings carry clear operational implications for radiology departments in tourist hotspots. Adaptive staffing models—such as seasonal hiring, flexible shift schedules, and on‑call radiologists—can mitigate bottlenecks during peak periods and curb unnecessary radiation exposure. Policymakers may also consider standardized protocols that incorporate rapid translation services and shared electronic health records to reduce diagnostic uncertainty for non‑residents. As travel rebounds post‑pandemic, hospitals that proactively align resources with fluctuating visitor volumes will likely achieve better patient outcomes and more efficient cost management. Investing in decision‑support tools that flag redundant studies could further streamline care while preserving diagnostic accuracy.
