Objectives: Studies have demonstrated associations between physicians' characteristics, specifically personal health behavior, and their reported prevention counseling behavior. This study, performed in 2007, examines associations between patients getting immunized against influenza and characteristics of their primary care physicians, including whether they themselves were immunized.
Methods: Computerized data were extracted on 29,447 patients aged 65 years and over registered in the largest health maintenance organization (HMO) in the Jerusalem area and on their primary care physicians. Further physician data were collected from a questionnaire distributed to a large sample of physicians. Logistic regression was performed with patient immunization as the dependent variable.
Results: Patients were more likely to get vaccinated if their physician was vaccinated and if the physician was female or a specialist or had studied in West Europe or America. Patients of physicians who reported exercising regularly and of physicians who knew that the vaccine can't cause influenza were also more likely to get immunized. These associations of physician factors with patient immunization, though statistically significant, were weaker than those previously reported with physician influenza vaccination counseling.
Conclusions: Physician's beliefs and medical education and personal health behavior are of importance in determining patient vaccination. An increase in population immunization rates may possibly be achieved by programs directed at enhancing physician knowledge and self immunization.
