ABSTRACT

OBJECTIVES: This article describes findings from the California Gonorrhea Surveillance System (CGSS), developed in response to the need for detailed risk behavior data and clinical data required to control increasing gonorrhea (GC) infections in California. METHODS: CGSS is a sample-based surveillance system implemented throughout California in 2007. In 34 of 61 local health jurisdictions (LHJs), 10% of GC cases are sampled for interview; in the other 27 LHJs, all cases are followed. A standardized case investigation record collects case-reported risk data and provider-reported clinical data, and is electronically prepopulated with available contact data. Exclusion criteria include age younger than 14 years, a GC diagnosis within the previous 30 days, and provider request that patient not be contacted. Analyses are weighted to account for sample design. RESULTS: In 2007, 31,192 cases of GC were reported in California. Of these, 5,388 were sampled for follow-up and 2,715 were interviewed, for a response rate of 54.2%. Of those interviewed, 49.6% were female, 28.8% were heterosexual males, and 21.6% were men who have sex with men (MSM). CGSS collects a wide range of behavioral and clinical data for targeted programmatic action. Findings from the 2007 CGSS included data on the following areas: incarceration (highest among heterosexual males [22.4%]); methamphetamine use (high overall [12.2%] and lower among African Americans [4.6%]); co-infection with human immunodeficiency virus (high among MSM [31.9%] and very low among heterosexual males and females [<0.5%]); and improper antibiotic use (8.3% overall; 25.6% among patients attending urgent care clinics). CONCLUSION: CGSS, an innovative sample-based surveillance system, is effective and flexible. The system provides actionable data on an ongoing basis.

ABSTRACT

OBJECTIVE: To describe trends in STD diagnostic test volume and test technology in California from 1996 to 2003. STUDY: A self-administered survey was mailed annually to licensed clinical laboratories in California that performed STD testing. Data were collected on volume and diagnostic test type for chlamydia, gonorrhea, syphilis, chancroid, HIV, hepatitis B, herpes simplex virus (HSV), and human papilloma virus (HPV). Data were analyzed for trends over time. RESULTS: Response rates ranged from 77% to 99% per survey year. The total number of chlamydia, gonorrhea, and syphilis tests increased from 8.1 to 9.3 million annually. The proportion of chlamydia and gonorrhea tests performed using nucleic acid amplification testing increased from 5% to 66% and from 1% to 59%, respectively. Gonorrhea culture testing decreased from 42% to 10% of all gonorrhea tests. HIV test volume increased from 2.4 to 3.1 million tests. Newer technology tests for HSV and HPV were less common but increased in use. Non-public health laboratories conducted over 90% of all STD testing. CONCLUSIONS: Analyzing trends in diagnostic technologies enhances our understanding of the epidemiology of STDs and monitoring laboratory capacity and practices facilitates implementation of STD control activities.
