The Evaluation of a Digital Health Intervention to Improve Human Papillomavirus Vaccine Recommendation Practices of Medical Students

We investigated what is being taught about HPV in US medical schools and evaluated a digital health intervention for medical students to increase their intention to provide a high-quality HPV vaccine recommendation. An online survey was emailed to Academic Deans at the 124 accredited US Schools of Medicine and Osteopathic Medicine between February and April 2018. A digital educational module was emailed to medical students in June 2020. A single-subject longitudinal study design was employed. Pre- post-survey administration measured change in knowledge, attitudes, subjective norms, perceived behavioral control, and intention to recommend HPV vaccine. Gaps in medical school curricula were found. Very few schools (~ 9%) reported teaching content on HPV prevention strategies or patient education. For the digital intervention, independent and dependent variables increased positively. Perceived behavioral control improved at significant levels as participants felt more confident addressing parents' concerns about the vaccine (p < 0.001) and more confident recommending the vaccine for patients (p < 0.05) post module. On the pre-survey, only 6% of the sample knew the most effective HPV vaccine communication style and on the post-survey 81% correctly identified it (p < 0.001). The intervention increased HPV and HPV vaccine knowledge, self-efficacy, and intention to provide a high-quality HPV vaccine recommendation to patients.
