Abstract
BACKGROUND: Understanding factors affecting trainee physician choices about vaccination may permit the design of more effective vaccination programmes. METHODS: To identify factors associated with seasonal and pandemic influenza vaccination, an online questionnaire based on the health belief model was sent to trainee physicians registered at the post-graduate medical education office at the University of Toronto in September 2011. RESULTS: 963 complete responses were received from 1884 trainee physicians (51%); 28 (2.9%) reported an allergy to vaccine components and were excluded from further analysis. Reported seasonal influenza vaccination rates in 2008, 2009 and 2010 were 69% (648/935), 75% (708/935) and 76% (703/935), respectively; 788 (84%) reported receiving the A(H1N1)pdm09 vaccine. In multivariable analysis, number of years of post-graduate training (OR for 4+ versus 1-3 post-graduate years 2.2 (95% CL 1.3, 3.8)) was associated with receipt of the 2009 pandemic vaccine, as were four components of the health belief model: odds ratios were 4.7 (95% CL 3.0, 7.5) for perceived severity, 1.9 (95% CL 1.2, 2.9) for perceived benefits, .35 (95% CL .21, .59) for perceived barriers, and 5.8 (95% CLI 3.6, 9.1) for external cues to action. Both vaccinated and unvaccinated respondents reported that their decisions were significantly influenced by encouragement from their colleagues, families and employers. CONCLUSION: Self-reported vaccination coverage among trainee physicians was high. External cues to action appear to be particularly important in trainee physician vaccination decisions: active institutional promotion may increase influenza vaccination rates in trainees.
