Seksueel overdraagbare aandoeningen in Noord-Nederland van 2010-2014: Een retrospectieve database studie

(2016) Koldenhof, A. (Anne)

Objectives
In this study, we mapped the Sexually Transmitted Infections (STI) trends and epidemiology in the Northern region of the Netherlands. Also, we compared and evaluated the different STI care providers in number of STI consultations, incidence, test-positivity rate and test location.
Methods
In this retrospective database study, all STI related laboratory results, between 1 January 2010 and 31 December 2014, were assessed (n=620,293). Data were retrieved from general practitioners, STI clinics, nursing homes, midwifery clinics and hospitals and were anonymously delivered by the two regional microbiology laboratories. First, a descriptive analysis was performed to assess the contribution of each STI care provider regarding the number of tests performed and number of positive diagnoses. The Linear-by-Linear Association test was performed to analyze the trends of STI. Associations between age, sex and socioeconomic status (SES) and the number of test positivity were explored by multivariable regression analyses.
Results
The biggest part of both STI consultations (53.75%) and number of STI tests (59.98%) was performed by general practitioners. Most of the extragenital tests were performed by the STI clinics. Within general practitioner practices, only 0.85% of all STI tests were extragenital. Of all extragenital tests, 54.79% was tested oropharyngeally and 32.27% was tested anorectally. The highest test-positivity rate was found in STI clinics (4.44%). In 7.49% of all STI consultations, a STI was found. Chlamydia is the most commonly diagnosed STI. The STI-positivity rate increased over time. There also was an increasing trend in test positivity of chlamydia and gonorrhea separately. For both general practitioners and STI clinics, extragenital test numbers increased over time.
Conclusion
The biggest part of both STI consultations and number of STI tests were performed by general practitioners. There are great differences in the number of extragenital tests between general practitioners and STI clinics. Through a detailed and complete surveillance system, which is achievable in this region of the Netherlands, it is possible to explore these differences. Insight in these differences can make it possible to supply STI care providers with specific advise. Extragenital testing needs to be encouraged, especially among general practitioners. Midwifes need to test more STI’s apart from HIV. Furthermore, a detailed and complete surveillance system enables further optimalisation of prevention programs and treatment.
