Factors associated with influenza and pneumococcal vaccination behavior among high-risk adults

OBJECTIVE: This cross-sectional survey assessed factors associated with influenza and pneumococcal vaccination behaviors among high-risk patients exposed to highly organized vaccination programs. INTERVENTIONS: Self- administered questionnaires were mailed to 700 patients randomly selected from the outpatient roster of the medical center. Questions were asked about patient demographic and health characteristics in addition to their knowledge and attitudes regarding influenza and pneumococcal diseases and vaccines. MAIN RESULTS: After three mailings, the response rate was 68%, and 80% of these respondents were in a high-risk roup. Influenza and pneumococcal vaccination rates for high-risk respondents were 74.4% and 62.5%, respectively. Factors independently associated with both influenza and pneumococcal vaccination behaviors included health care providers' recommendations and having positive attitudes toward immunization. In addition, for influenza vaccination, willingness to comply with the provider's recommendation was also associated with receipt of the vaccine while cigarette smoking was associated with failure to receive the vaccine. CONCLUSIONS: Emphasis on provider recommendations and the knowledge and attitudes of patients may enhance influenza and pneumococcal vaccination rates, even in the context of organized vaccination programs.
