Background: Seasonal influenza vaccination is recommended for all adults; however, little is known about how primary care physicians can communicate effectively with patients about influenza vaccination.
Objective: To assess among general internal medicine (GIM) and family physicians (FP) regarding adult influenza vaccination: (1) recommendation and administration practices, (2) barriers to discussing and perceived reasons for patient refusal, and (3) factors associated with physician self-efficacy in convincing patients to be vaccinated.
Design: Email and mail survey conducted in February-March 2017 PARTICIPANTS: Nationally representative sample of GIM and FP MAIN MEASURES: Factor analysis was used to group similar items for multivariable analysis of barriers and strategies associated with high physician self-efficacy about convincing patients to be vaccinated (defined as disagreeing that they could do nothing to change resistant patients' minds).
Key results: Response rate was 67% (620/930). Ninety-eight percent always/almost always recommended influenza vaccine to adults ≥ 65 years, 90% for adults 50-64 years, and 75% for adults 19-49 years. Standing orders (76%) and electronic alerts (64%) were the most commonly used practice-based immunization strategies. Frequently reported barriers to discussing vaccination were other health issues taking precedence (41%), time (29%), and feeling they were unlikely to change patients' minds (24%). Fifty-eight percent of physicians reported high self-efficacy about convincing patients to be vaccinated; these providers reported fewer patient belief barriers contributing to vaccine refusal (RR = 0.93 per item; 95% CI (0.89-0.98); Cronbach's α = 0.70), were more likely to report using both fact- (1.08/item; (1.03-1.14); 0.66) and personal experience-based (1.07/item; (1.003-1.15); 0.65) communication strategies, and were more likely to work in practices using patient reminders for influenza vaccine (1.32; (1.16-1.50)).
Conclusions: Physicians identified barriers to successfully communicating about adult influenza vaccination but few effective strategies to counter them. Interventions to promote self-efficacy in communication and under-utilized practice-based immunization strategies are needed.
