Evaluation of online educational curriculum on HPV vaccination practices among adult primary care providers

Background Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States. While HPV is a vaccine-preventable illness, vaccine utilization rates in the United States remain low, particularly among adults. Methods The objective of this study was to assess the impact of an online, asynchronous educational module on HPV vaccination for adult primary care providers. We designed and implemented the module for family medicine, internal medicine, medicine/pediatrics, and obstetrics/gynecology providers in a community practice network affiliated with a large academic health system. We evaluated the effect of the module on provider knowledge, attitudes, and self-reported behaviors with pre-, post-, and delayed post-tests, using Likert-scales for measurement. We summarized data with descriptive statistics and compared changes in individuals using paired t-tests. Results One hundred forty-four out of 223 providers completed the module (response rate of 65%). At baseline, internists had the lowest knowledge scores compared to other specialties (pre-test mean of 3.6, out of 5, SD 1.2). Internists were also the least likely to counsel patients on HPV vaccination (mean 1.6, SD 0.9). There was a statistically significant improvement in knowledge from pre-test to post-test (from mean of 3.8 to 4.6, out of 5, p < .001) across all specialties. There was also statistically significant improvement in mean confidence for all providers from pre-test to post-test to identify patients aged 19–26 (3.3 to 3.7, p < .001) and patients aged 27–45 (2.7 to 3.5, p < .001) who needed vaccination. There was a statistically significant improvement in likelihood to counsel eligible patients on the risks of HPV infection (mean 2.3 to 2.8, p -value 0.002). The delayed post-test demonstrated retention of improved knowledge, confidence, and self-reported behavior. Conclusions This study demonstrated that an asynchronous online module was effective at improving confidence, knowledge, and self-reported behavior of adult primary care providers in recommending HPV immunization. Given the important role that healthcare providers play in vaccine uptake, this study suggests that an online educational intervention can be a powerful tool to encourage increased utilization and delivery of the HPV vaccine. Further efforts are needed to educate internists and providers who take care of the adult population on HPV vaccination.
