Lessons learned from a population-based chlamydia screening pilot

Abstract

We evaluated process organization and response optimization in a home-based Chlamydia trachomatis (Ct) screening project in the Netherlands among 15- to 29-year-old women and men. The method used was computer-supported data flow, from population sampling to informing participants of the result. A new test kit or a letter reminded non-respondents after six weeks. Fifteen-year olds required parental consent. Urine arrived at the laboratory within 29 days from invitation, and four (1–11) days after collection, indicating good specimen quality. Test kits had a higher response than letters (15 versus 10%). Response in 15-year olds was 33%; with 2% Ct infected sexually active 15 year olds. In Conclusion, purpose made computer software is essential for an efficient screening programme. Sending urine by mail does not impair diagnostics. Reminders are necessary and effective after four weeks. Necessary parental consent for under 16-year olds should not be a deterrent to offer Ct screening to this age group.
