Emergency departments could help boost annual flu vaccination rates
A University of California, Riverside-led study found that while 96% of over 3,200 U.S. emergency department patients were aware of the flu vaccine, only 41.6% had received it in the past year. The research suggests emergency departments could significantly boost vaccination rates, especially among underserved populations lacking primary care access.
A study led by Dr. Robert Rodriguez at the University of California, Riverside, analyzed 3,285 adult patients across 10 emergency departments in eight U.S. cities between April and December 2024. The findings, published in the *Journal of Emergency Medicine*, revealed that 96% of participants had heard of the influenza vaccine, yet only 41.6% were up to date with their annual vaccination. Patients without primary care providers were over twice as likely to be behind on vaccinations, with similar disparities among uninsured individuals and African American patients. The study highlighted a critical opportunity for emergency departments (EDs) to improve vaccination rates, as 37% of unvaccinated patients expressed willingness to receive a flu shot during their ED visit. Researchers noted that EDs often serve as the sole healthcare point of contact for many patients, particularly those with limited access to preventive care. Dr. Rajesh Gulati, a coauthor, emphasized that EDs could act as a 'public health safety net' for preventive services like flu vaccinations. Common reasons for declining vaccination included fear of side effects, insufficient information, and feeling too ill at the time of the visit. The study also identified lack of primary care access as the strongest predictor of delayed vaccination, with over 20% of participants reporting no primary care provider. Dr. Sanya Dhama, the study’s lead author, stressed that targeted outreach and educational messaging could further increase acceptance. The research was conducted in EDs across Chicago, Detroit, Durham, Philadelphia, Fresno, Los Angeles, San Francisco, and Sylmar. It underscored the potential of ED-based vaccination programs to reduce influenza-related illness, hospitalization, and death, particularly among underserved populations. The study was supported in part by the National Institute of Allergy and Infectious Diseases. Rodriguez and his team concluded that emergency departments represent an underutilized venue for vaccine delivery, surveillance, and education. Expanding ED-based vaccination initiatives could help address gaps in flu vaccination coverage and improve public health outcomes.
