Assessing a Continuing Education Course for Dental Hygienists to Improve HPV and HPV Vaccine Knowledge and Self-efficacy.

Human papillomavirus is the most common sexually transmitted infection and causes anogenital and oropharyngeal cancers. Although HPV-related cancers can be prevented through vaccination, HPV vaccination rates are low compared to other vaccines. One of the strongest indicators for vaccination is provider recommendation, and dental health providers are well positioned to promote HPV vaccination among their patients. The purpose of this study was to determine if a continuing education (CE) course could improve dental hygienists' HPV-related knowledge and self-efficacy related to HPV vaccination recommendations. Data were collected from a sample of participants (n = 202) at a large dental hygiene conference in the southern US. A pre- and post-tests were administered with the CE course and differences in HPV vaccine knowledge and self-efficacy in counseling, recommending, and referring for the HPV vaccine were analyzed using SAS. HPV vaccine knowledge overall significantly increased post-CE (p < .001) and improvement was seen among several specific knowledge areas. However, knowledge regarding the common sites of HPV-related oral and oropharyngeal cancers remained moderate (82% correct) even after the CE intervention. There was no significant change from pre-test to post-test in participants' self-efficacy related to counseling patients about the HPV vaccine, recommending the HPV vaccine to patients, or referring patients for the vaccine. This study demonstrates that continuing education can improve dental hygienists' HPV-related knowledge. Since dental providers may play an important role in HPV-related cancer prevention, future work should develop continuing education tools that can motivate changes in self-efficacy and ultimately improve practice behaviors.
