Medical Students' Efforts to Address COVID-19 Vaccine Hesitancy Through Motivational Interviewing.

Background The coronavirus disease 2019 (COVID-19) pandemic reaffirmed health disparities in the United States (US) and highlighted the need for public health strategies to combat vaccine hesitancy, especially amongst vulnerable populations. The Green Family Foundation Neighborhood Health Education Learning Program (NeighborhoodHELP) at Florida International University (FIU) serves a predominantly uninsured population, making it a critical area of opportunity for addressing vaccine hesitancy. Motivational interviewing (MI), a technique that supports individuals in making autonomous health decisions, has shown promise in encouraging vaccine acceptance. Medical students at FIU's Herbert Wertheim College of Medicine (HWCOM) are involved in the longitudinal care of the individuals in NeighborhoodHELP and receive training in MI within their clinical skills curriculum, making them optimally positioned to conduct outreach to encourage COVID-19 vaccination. Project goals There were two primary goals of this project: first, to systematically track and improve COVID-19 vaccination rates among individuals in NeighborhoodHELP, and second, to equip future physicians with hands-on experience in MI. Methods The COVID-19 Vaccination Promotion Initiative recruited medical students previously trained in MI to conduct outreach to unvaccinated individuals within NeighborhoodHELP. Students engaged in discussions about the COVID-19 vaccine with NeighborhoodHELP members, assisted in scheduling vaccination appointments, and updated medical records. The student team regularly met with faculty advisors to discuss changes in vaccine and public health data and to discuss challenges and successes with outreach efforts. To incentivize participation and enhance vaccine uptake, $25 gift cards were offered to individuals who agreed to receive the vaccine following the outreach conversations. Results From June 2021 to January 2023, the team made an estimated 720-1516 phone calls to NeighborhoodHELP individuals. The team encountered a challenge of low answering rates, with 35% of individuals being unreachable despite multiple attempts. Among those reached, 20% expressed no interest in receiving the vaccine, while 50% were interested in receiving the vaccine or had already been vaccinated. Vaccination rates among NeighborhoodHELP adults rose from 15.2% to 44.3% during this time. Student experiences with MI were generally positive, with many noting success in engaging hesitant individuals. However, the team also encountered challenges, such as growing vaccine apathy within the community and difficulties in reaching patients via cold calls, which limited the overall impact of their outreach efforts. Conclusions By using MI techniques, medical students engaged with community members in meaningful conversations about the importance and safety of COVID-19 vaccination. However, the initiative fell short of the 50% vaccination target, facing challenges such as reliance on unsolicited phone calls and the complexities of incentivizing vaccinations through this outreach method.  Future initiatives could benefit from exploring alternative outreach methods, such as in-person engagement at community events or through partnerships with local organizations, to overcome the limitations of phone-based outreach. Additionally, investigating the relative efficacy of in-person versus telephone-based communication in promoting vaccination could provide valuable insights.
