Survey of Adult Influenza Vaccination Practices and Perspectives Among US Primary Care Providers (2016-2017 Influenza Season).

backgroundSeasonal influenza vaccination is recommended for all adults; however, little is known about how primary care physicians can communicate effectively with patients about influenza vaccination.

objectiveTo 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.

designEmail and mail survey conducted in February-March 2017

participantsNationally 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

resultsResponse 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)).

conclusionsPhysicians 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.
