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.

Impact of HPV Immunization Training on Dental Hygiene Students' Attitudes and Confidence Regarding HPV Preventive Education.

Human Papilloma Virus (HPV)-related oropharyngeal cancers (OPC) have increased significantly despite availability of the HPV vaccine. HPV-positive oropharyngeal cancer is becoming more prevalent than tobacco-related OPC. Dental professionals screen for OPC and risk factors, but many are not prepared to address HPV immunization and prevention with patients. The aim of this study was to implement and assess a training module on HPV to increase dental providers' knowledge, promote confidence in their ability to provide effective prevention interventions, and instill a positive attitude about recommending HPV immunization to their patients. The study used a pretest-posttest design. Participants were dental hygiene students in one U.S. dental hygiene program in 2017. The students completed the pretest, then viewed the online training module, and completed the posttest one week later. Of the 40 students who participated in the module, 37 completed both pretest and posttest, for a response rate of 93%. From pretest to posttest, the respondents showed a significant increase (CI=0.5, p<0.001) in knowledge of HPV prevention with mean scores increasing from 8.75 to 13.32 on a 15-point scale. The students demonstrated an increase (p<0.05) in confidence and comfort in providing HPV immunization counseling on the posttest, as well as an increase (p<0.05) in positive attitudes about recommending HPV immunization. This study found that the participants' knowledge and confidence regarding HPV, HPV-related OPC, and HPV immunization increased after the module, suggesting that effective education and preparation for HPV counseling can be accomplished through modular-based education. This education would be beneficial in an institutional or professional setting.

Factors affecting the performance of oral cancer screenings by Texas dental hygienists.

PURPOSE: The 5 year survival rates for oral cancer have not changed in the last 50 years. A simple intra- and extra-oral examination provided by health care professionals could help to reduce morbidity and mortality of oral cancer. This study focused on Texas dental hygienists' performance of oral cancer screenings (OCS) and factors that influenced their performance of this examination. METHODS: A 33 question survey of 608 randomly selected Texas dental hygienists was conducted. Frequency, chi-square and Spearman correlation tests were performed. RESULTS: Three hundred and six hygienists replied and provided the data for this study. The data indicated that 45.8% "always" performed OCS, 23.5% performed OCS at the initial appointment and 47.4% at the recall appointment. Experience and comfort level were the greatest influences on OCS performance. Dental hygienists practicing for 16 or more years performed OCS 51.2% of the time, while those with only 0 to 5 years of experience performed OCS 25.5% of the time. A statistically significant correlation (ρ=0.15, p<0.007) was found be tween years of experience and performance of OCS. A significant correlation (ρ=0.18, p<0.001) was found between the identification of a suspicious lesion and the performance of OCS. Forty-nine percent of dental hygienists reported feeling "very comfortable" with intra-oral examinations, but only 26.5% felt "very comfortable" with extra-oral examinations. A statistically significant correlation (ρ=0.16, p<0.001) was found between comfort level in the performance of an OCS and reported frequency of OCS. The majority of subjects performed poorly on the knowledge portion of the survey (mean=53%). There was a significant correlation (ρ=0.22, p<0.001) between attendance at OCS continuing education courses and the performance of OCS. CONCLUSION: Dental hygienists' knowledge about oral cancer was not current and comfort levels with performing OCS were low. These indicate a need for a stronger emphasis on the importance of OCS for students during dental hygiene education and a more thorough continuing education for practicing dental hygienists.
