Lack of knowledge, not vaccine hesitancy, is the main cause of low human papilloma virus vaccination rate among systemic lupus erythematosus patients in Japan after suspension of proactive recommendation: Analysis of a patients' survey

Abstract

Objective

To identify the factors that inhibit human papilloma virus (HPV) vaccination to improve the high HPV infection rate and cervical cancer incidence among SLE patients.

Methods

We conducted a questionnaire survey of female SLE patients aged 18–45 years attending our hospital to analyze factors related to HPV vaccination.

Results

We obtained responses of 88 participants. Only 5 (5.7%) were received HPV vaccination, 15 (17.0%) were uncertain of their vaccine history, and 27 (30.7%) had never even heard of HPV vaccination. The reasons for unvaccinated against HPV were “don't know” with 24 participants, “missed opportunity” with 15, and “troublesome, somehow” with 8. The most trusted source of medical information for the unvaccinated was their physician (69, 60.2%). Among the unvaccinated, those who wished to be vaccinated in the future were positively correlated with “trust of vaccine benefit” (r = 0.561, p = 0.005) and “general knowledge about HPV vaccine” (r = 0.512, p = 0.013), and negatively correlated with “negative attitudes toward vaccination and vaccine policy” (r = −0.547, p = 0.007).

Conclusion

HPV vaccination rate among SLE patients in Japan was extremely low. The main reason was lack of knowledge. The most effective solution is considered to provide accurate information and adequate recommendations of HPV vaccination by attending physicians.
