587. Vaccine knowledge, attitudes, and practices among New York State healthcare providers

Abstract Background Vaccine attitudes of healthcare providers (HCPs) influence patient vaccine acceptance. We sought to characterize vaccine knowledge, attitudes, and practices (KAP) among HCPs in NYS. Methods An electronic survey was developed to assess vaccine KAP among HCPs. The questionnaires were sent to members of various national medical organizations via local chapter administrators. Results 864 surveys were returned from 672 (78%) physicians and 192 (22%) mid-level practitioners (MLPs). 624/724 (86%) of HCPs report always recommending routine vaccines to eligible patients, yet only 76% recommend influenza vaccine (IV) and 77% strongly recommend HPV vaccine at 11-12 yrs. MLPs had a higher mean agreement level that recommending vaccines (4.6 vs 4.2 p < 0.01) or promoting HPV vaccine (4.2 vs. 3.9 p < 0.05) is within their scope of practice. Physicians had a higher mean agreement level that: vaccine benefits outweigh risks (4.9 vs 4.6 p < 0.01), HPV vaccine prevents cancer (4.7 vs 4.5 p < 0.01), and COVID-19 vaccine is safe (4.8 vs 4.5 p < 0.01) and effective (4.8 vs 4.7 p < 0.01). 82% (680/825) of HCPs knew that vaccines should not be deferred for mild illness. 14/836 (2%) believed that HPV vaccine could increase sexual activity, while 273/705 (39%) knew that the most common HPV associated malignancy is oropharyngeal cancer. HCPs who correctly answered ≥ 5/7 questions (462/507 91%) were more likely to recommend all vaccines to eligible patients than HCPs with lower scores (22/40 50% p < 0.05). Routine IV recommendation was more likely among HCPs who: strongly disagree that influenza is not serious enough for vaccination (292/397 (74%) vs 137/249 (55%) p < 0.01), strongly agree that it prevents severe disease (267/352 (76%) vs 162/294 (55%) p < 0.01), and receive annual IV (423/629 (67%) vs 6/17 (35%)) p < 0.01). HPV vaccine recommendation at 11-12 years was more likely among HCPs who strongly agree that the vaccine prevents cancer (273/326 (84%) vs 48/86, 56% p < 0.01) and those who stated that vaccination does not increase risk of unprotected sex (316/392 (79%) vs 3/12 (25%) p < 0.01). Conclusion Vaccine recommendation practices are influenced by HCP vaccine misperceptions and hesitancy. Interventions to reduce misperceptions and improve vaccine confidence are needed.
