| rationale, design, and results of the first screening round of a comprehensive, register-based, chlamydia screening implementation programme in the netherlands. | implementing chlamydia trachomatis screening in the netherlands has been a point of debate for several years. the national health council advised against implementing nationwide screening until additional data collected from a pilot project in 2003 suggested that screening by risk profiles could be effective. a continuous increase in infections recorded in the national surveillance database affirmed the need for a more active approach. here, we describe the rationale, design, and implementation ... | 2010 | 20925966 |

| overestimation of complication rates in evaluations of chlamydia trachomatis screening programmes--implications for cost-effectiveness analyses. | cost-effectiveness analyses of screening programmes for asymptomatic chlamydia trachomatis infection suggest that screening at low prevalences in the population is cost-effective. however, the decision models in these studies are based on assumptions about the risk of complications, which are derived from the literature. incorrect assumptions may lead to under- or overestimation of the effectiveness of screening. the first objective of this paper is to evaluate the assumptions about the probabil ... | 2004 | 15082651 |
