Exploring Current Practice, Knowledge, and Challenges of Sexually Transmitted Infection/HIV Management and Pre-Exposure Prophylaxis Among Japanese Health Care Professionals: A Cross-Sectional Web Survey

We conducted a web-based survey targeting physicians in specialties of treating sexually transmitted infection (STI) and/or human immunodeficiency virus (HIV) patients to understand the current STI/HIV care practices and their acceptability of and barriers to the prescription of pre-exposure prophylaxis (PrEP) in Japan. A descriptive analysis was used to summarize survey responses. Univariate and multivariable logistic regression were performed to identify factors associated with willingness to prescribe PrEP. Of 316 survey respondents, 57 were specialized in HIV, 90 STI/Urology/Proctology, 55 Obstetrics/Gynecology, and 114 General Practice/Internal Medicine/Dermatology. Proportion of HIV-specialized physicians who interview the patients about risk behaviors tended to be higher than other physician groups (84.2% vs. 54.8%, 47.3%, and 50.9%, respectively), and 53 - 75% of non-HIV-specialized physicians reported that they were incapable of making decisions on HIV medications. Higher PrEP knowledge enhanced the willingness to recommend and prescribe PrEP drugs (odds ratio: 2.31, 95% confidence interval: 1.30-4.10, p = 0.0044), and 45.4% physicians with no PrEP knowledge raised the concern of incapability to respond and manage when an individual is infected with HIV. Educational opportunities on management and prevention measures for both STI and HIV may encourage non-HIV-specialized physicians to be involved in HIV care and to enhance initiation of HIV tests and adoption of PrEP.
