Despite long-standing recommendations for non-elderly adults with certain chronic pulmonary, cardiovascular and metabolic conditions to receive influenza vaccine, vaccination rates remain low. Visits to subspecialists represent an important vaccination opportunity, but little is known regarding subspecialists' perceptions related to influenza vaccination. In February 2003, we conducted a cross-sectional mail survey of a random sample (N = 2,007) of board-certified cardiologists, endocrinologists and pulmonologists from the entire United States who provided outpatient care to adults aged 18-64 years, to assess their patterns of and attitudes toward administering influenza vaccine to high-risk, non-elderly patients. The overall response rate was 33%. Among 621 eligible respondents, 483 stocked influenza vaccine in their practice (Stockers) and 138 did not stock the vaccine (Non-Stockers). Pulmonologists were most likely to stock vaccine and strongly recommend vaccination; cardiologists were least likely. Among Stockers, barriers to vaccination varied by subspecialty. Among Non-Stockers, the most common factor in the decision to not stock vaccine was the perception that patients will receive the vaccine elsewhere. Most subspecialists who provide care to a large proportion of high-risk, non-elderly persons recommend influenza vaccination to some degree, particularly pulmonologists. To reduce missed opportunities overall, subspecialists should be encouraged to vaccinate patients who say that they plan to get the vaccine elsewhere. For cardiologists in particular, barriers to stocking influenza vaccine and recommending vaccination more strongly must be addressed.
