Population-based surveillance of medical tourism among US residents from 11 states and territories: Findings from the Behavioral Risk Factor Surveillance System

Objective: To describe medical tourism among a subset of US residents; identify possible indicators for medical tourism. Methods: The US Centers for Disease Control and Prevention collaborated with 11 states and territories to ask 6 questions about medical tourism, using the Behavioral Risk Factor Surveillance System. Data collected from January 1, 2016, through December 31, 2016, included whether respondents traveled internationally for preplanned care, travel reasons and destinations, procedures received, and occurrence and treatment of complications. A descriptive analysis of demographics, socioeconomic status and health access variables was performed, and a regression model with a log-link function and Poisson distribution was used to estimate prevalence ratios (PR) for medical tourism. Results: Of 93,492 respondents, 517 (0.55%) traveled internationally during the previous year for care. Mexico was the most common destination (41% of trips). Dentistry accounted for 55% of treatments. Complications from care received abroad were reported by 5% of medical tourists; 67% sought care upon returning to the United States. The prevalence of medical tourism was 1.32% (95% CI, 1.00-1.64). The prevalence of medical tourism was higher in Hispanics and non-whites (PR, 3.97; 95% CI, 2.48-6.32) and higher among those without current health insurance (PR, 2.70; 95% CI, 1.69-4.34). Conclusions: This is the largest collection of population-based surveillance data describing medical tourism among US residents from multiple states and territories. Understanding the demographic and socioeconomic factors associated with medical tourism can inform evidence-based recommendations for travelers and clinicians who may advise or care for these individuals before, during, or after travel.

Automated summary

This study described medical tourism among US residents from multiple states and territories. The prevalence of medical tourism was estimated, and it was found to be higher in Hispanics, non-whites, and those without health insurance.
