Factors inhibiting use of the pneumococcal polysaccharide vaccine: a survey of Connecticut physicians.
BACKGROUND
The pneumococcal polysaccharide vaccine (PPV) is effective in preventing invasive pneumococcal disease, but remains underutilized. Prior surveys of physicians revealed concern regarding the safety and efficacy of the vaccine, but there has been little information published in the last 10 years that sheds light on why the vaccine remains underutilized. Although there is currently emphasis on providing PPV to hospitalized patients, there is even less known about what factors prevent PPV use in the hospital setting and chronic care setting. We performed a survey of physicians in Connecticut to determine what factors prevent utilization of the vaccine in three patient care settings.


METHODS
A survey of internists and family practitioners in Connecticut that ascertained their frequency of utilization of PPV and what factors inhibited utilization of PPV.


RESULTS
Three hundred ninety-seven responses are included in the analysis. Forgetting to administer the vaccine (59% of respondents) and patient refusal (55% of respondents) were the factors most frequently noted as being important in preventing vaccination in the outpatient setting. In the inpatient and chronic care settings, difficulty in determining the patient's vaccine status was also noted. Concerns regarding the efficacy or safety of the vaccine did not seem to be important. The factor that correlated most closely with the respondents' reported frequency of vaccine use was forgetting to vaccinate.


CONCLUSIONS
Physicians, although accepting the efficacy of PPV, are inhibited from its more frequent use by several factors.
