To describe trends in STD diagnostic test volume and test technology in California from 1996 to 2003.
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.
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.
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.

    • "Monitoring trends in the use of diagnostic methods enhances STI control efforts by improving the interpretation of STI trends, creating valuable partnerships with laboratories, facilitating the evaluation of screening programs and investigating outbreaks [28]. With the continuous development and improvement of diagnostic methods it is obvious that there have been changes since this survey was performed. "

    ABSTRACT: Sexual transmitted infections (STIs) have increased in Germany and other countries in Europe since the mid-nineties. To obtain a better picture of diagnostic methods used in STI testing institutions in Germany, we performed a nationwide survey amongst STI specialists in order to evaluate the quality of STI reports and provide recommendations to harmonize and possibly improve STI diagnostics in Germany. We asked sentinel physicians and randomly chosen gynaecologists, urologists and dermato-venerologists, about the diagnostic methods used in 2005 to diagnose HIV, chlamydia (CT), gonorrhoea (GO) and syphilis (SY) in a national cross-sectional survey in order to recognize potential problems and provide recommendations. A total of 739/2287 (32%) physicians participated. Of all participants, 80% offered tests for HIV, 84% for CT, 83% for GO and 83% for SY. Of all participants who performed HIV testing, 90% requested an antibody test, 3% a rapid test and 1% a nucleic acid amplification test (NAAT). For CT testing, NAAT was used in 33% and rapid tests in 34% of participants. GO resistance testing was performed by 31% of the participants. SY testing was performed in 98% by serology. Diagnostic methods for STI vary highly among the participants. Diagnostic guidelines should be reviewed and harmonised to ensure consistent use of the optimal STI diagnostic methods.

    ABSTRACT: We established a pilot sentinel surveillance system for Neisseria gonorrhoeae infection in Tainan to evaluate underreporting in the National Gonorrhea Notifiable Disease System (NGNDS), and also conducted a survey to understand physicians' specific reasons for underreporting in the Tainan region. A sentinel surveillance network consisting of six specialty clinics was created in Tainan City. Three hundred seventeen patients who were clinically diagnosed with urethritis, cervicitis, or gonorrhea were enrolled. N. gonorrhoeae infection was detected by urine-based PCR. A questionnaire was mailed to healthcare providers who potentially see patients with gonorrhea in the Tainan region. Forty-eight N. gonorrhoeae-positive subjects were identified from the sentinel surveillance, and none of these gonorrhea cases were notified to the NGNDS by their healthcare providers. During the study period, there were 67 notified cases in the NGNDS, depicting an underestimation of at least 42% for this epidemic. Of the 16 healthcare providers who had seen cases in the past 3 months, only seven (43.8%) reported that they notified the authorities and only 23 (32%) of 71 cases were reported. 'Not collecting a specimen' and 'afraid of the invasion of patient privacy by the authorities' were the main reasons for the lack of notification. The underreporting of gonorrhea identified in this pilot is substantial. An overhaul of Taiwan's NGNDS that streamlines the reporting procedures and the requirement for laboratory confirmation, along with a continuing medical education program is warranted.
