Barriers to immunization--an examination of factors that influence the application of pneumococcal vaccine by house staff.
Pneumococcal infection is a leading cause of adult morbidity and mortality in the United States. Immunization against this infection is a valuable strategy in preventive medicine. An effective pneumococcal vaccine has been available in this country for over a decade, but it remains poorly utilized. The purpose of the present investigation was to analyse the factors that affect the use and administration of the pneumococcal vaccine and to identify barriers to use. Upper-level internal medicine residents (n = 33) from two medical clinics associated with an academic medical centre completed an explanatory survey. This explored the levels of house-staff knowledge, perception and attitudes regarding the vaccine and the existence of practical barriers against its utilization. chi 2 analyses and z tests were carried out to determine significance, where appropriate. The majority of the house staff (22, 66.7%) answered correctly regarding vaccine target groups, and all residents indicated that they generally obtain a vaccination history in adult patient evaluation. However, a sizeable number (14, 42.4%) did not indicate a time of the year when they routinely administered vaccines to patients. They were not confident about their knowledge regarding vaccine guidelines (23, 69.7%) and had an exaggerated fear of hypersensitivity reactions from immunization (20, 60.6%). Neither the expense of the vaccine nor adverse publicity were impediments to immunization (24, 72.7% and 28, 84.8%, respectively). Although most physicians knew of the usefulness of the vaccine (31, 93.9%), many failed to translate this knowledge into clinical practice (22, 66.7%). 'Pressing' clinical issues were viewed as barriers to vaccination (18, 54.5%) and placed the practice of preventive medicine in a subordinate position.(ABSTRACT TRUNCATED AT 250 WORDS)
