Screening for bacterial STIs, in particular chlamydia, is common in high income countries using a variety of different approaches. However, recent reductions in funding for STI treatment services in several countries highlight the need to ensure that investment in screening remains appropriate and cost-effective. The evidence base for chlamydia screening suggests that it can reduce the incidence of pelvic inflammatory disease but with several caveats, and it remains unclear whether screening represents good value for money. In particular, the opportunity cost of choosing screening over other sexual health interventions requires consideration. Harms have been poorly characterised but need to be addressed when measuring the potential value of a screening program. Overall, the evidence for broad population based screening is limited and new approaches are needed to reduce the morbidity and reproductive sequelae associated with bacterial STIs.
