Vaccination practices in U.S. emergency departments, 1992-2000

Abstract

To determine how frequently emergency department (ED) patients are vaccinated against influenza and pneumococcus, we analyzed all adult ED vaccinations in the combined databases of the annual National Hospital Ambulatory Medical Care Surveys, 1992-2000. During this period, EDs gave 27,738,000 vaccinations (95%CI: 25,878,000-29,598,000). Of these, 93% (87-100%) were against tetanus. The count of pneumococcal or influenza vaccinations was too small to permit estimation of a national total. Large-scale vaccination of ED patients appears feasible, given the tetanus experience, but ED patients are rarely vaccinated against influenza or pneumococcus. Reasons for this disconnect between burden of disease and preventive practices are discussed.
