  • Background: To impede ongoing hepatitis B transmission among unvaccinated adults with risk behaviors, the Centers for Disease Control and Prevention recommends hepatitis B vaccination in individuals seeking evaluation or treatment for sexually transmitted infections (STIs). We examined rates and correlates of hepatitis B screening and vaccination in a cohort of insured adults in Kaiser Permanente Southern California.

    Methods:  We examined electronic health records of 538,174 adults diagnosed or tested for chlamydia, gonorrhea, syphilis, genital herpes, genital warts or trichomoniasis from 2008-2011, and who had no evidence of prior hepatitis B infection, immunity or vaccination. Women <25 years with only chlamydia and/or gonorrhea tests were excluded. Logistic regression models were used to determine correlates of hepatitis B screening at the time of STI testing or diagnosis, and vaccination among those tested susceptible, adjusted for calendar year, membership length, and number of clinic visits in the previous year.

    Results: Among 504,407 eligible adults, 76,254 were screened (15.1%). Screening rates were higher among males, those aged 18-24 years, and Asians (Fig. 1). Among 2,930 tested hepatitis B susceptible adults, 690 (23.5%) received ≥ 1 dose of vaccine and 446 (15.2%) received the first dose within 90 days. In adjusted analysis, adults aged 25-34 years were more likely to be screened than those in other age groups (P<.05). Females were less likely to be screened (0.70 [0.67-0.73]). Asians (1.66 [1.54-1.78]), those lived in neighborhood with higher education attainment levels, and those with a history of diabetes, chronic liver or kidney diseases (1.22 [1.13-1.32]) were more likely to be screened. Among those tested susceptible, likelihood of vaccination did not differ significantly by age or sex. Asians (1.66 [1.17-2.35]) and those with a history of diabetes, chronic liver or kidney diseases (1.40 [1.06-1.84]) were more likely to be vaccinated.

    Conclusion: Hepatitis B screening and vaccination rates were low in adults diagnosed or tested for STIs. Targeted interventions among healthcare providers may increase awareness and lead to improved HBV vaccination in this at risk population.
