Comprehensive Evaluation of the Syphilis Surveillance System
• Over period of 1999-2000, the SEP performed evaluation of surveillance system following CDC guidelines
• 18 recommendations generated
• Most have been implemented, others are in process of implementation
Elements of Enhanced Syphilis Surveillance in Baltimore
• Expanded data collection (especially behavioral risks)
• Enhanced syphilis interview
• Jail Stat Lab project
• Cross-jurisdictional data sharing
• Expanded community screening
Behavioral Risk (Local Use) Variables
• Collected on all syphilis cases as part of Original Patient Interview
• Immediately indicates membership in suspected high prevalence networks
• People who in engage in these behaviors are considered integral to spread of syphilis
Local Use Variables

Congenital Syphilis Supplemental Data Collection
• CDC 126 form can be limited for diagnosing CS risks
• Designed supplemental data collection form to be used with CS investigations
• Presently collect detailed data on:– Prenatal care during each trimester– If no prenatal care, reason(s) why– Drug screen information– Risk history of mother
Modified Interview: The Syphilis Assessment
• Since December 2000, syphilis cases have been asked to identify locations where they met their sex partner(s)
• Cases also report on risk behaviors occurring at these meeting places
Assessment Form
-Focuses on where cases met their sex partners
-Scanned into a database
-Places and risks are mapped using GIS software
Sex Partner Meeting Places (n=55)
Street/Corner 53%
Private residence 13%
Bar/club 9%
Strip club 6%
Workplace/office 4%
Park 4%
Other/Unknown 13%
Stat Lab Project
• Jail-based rapid disease intervention initiative
• Prevalence monitoring of high-risk population
• Partnering with local SE activities

Cross-Jurisdictional Data Sharing
• Assessment forms used by Baltimore are also used in surrounding counties, including jails.
• Jail screening data (under jurisdiction of MD state), can now be shared for more complete syphilis histories
Enhanced Community Screening
• “Piggyback” syphilis screening at sites where blood is being drawn for HIV test
• Create leadership through funding key CBO partners
• Partner with community clinics
• Rapid Response Team outreach screening
Conclusion
• Creating an effective “tool”– Multi-pronged approached– Representative
• Data supported interventions
• Community Involvement– Community– Community– Community
