Automated interviewing for hepatitis B risk assessment and vaccination referral.
BACKGROUND
This study describes a convenient, anonymous, and private method to assess risk for hepatitis B and recommend vaccination for those determined to be at risk.


METHODS
We used an automated telephone interview and computerized risk assessment to inform callers of their hepatitis B risk status and direct those at risk for testing, counseling, and vaccination. The project's efficacy was compared to previously reported projects, and the expense was compared to estimates assuming universal vaccination.


RESULTS
This pilot project found that 63% of completed interviews indicated risk. Of those at risk, 47% reported for testing, and 89% of those tested required vaccination. Of those requiring vaccine, 75% (32% of at-risk callers) completed the three-dose series. Of those tested, 9% previously had natural infections and 2% were carriers.


CONCLUSIONS
Until adolescents are universally vaccinated, computerized hepatitis B risk assessment can facilitate prevention and decrease vaccination program costs. Privacy and anonymity may increase participation of groups difficult to reach before the onset of risky behaviors that results in treatment for STDs and drug abuse.
