A Cost-effectiveness Analysis of Screening and Treatment for <i>Chlamydia trachomatis</i> Infection in Asymptomatic Women

Abstract

For asymptomatic female carriers of C. trachomatis, screening with a DNA amplification assay combined with the single-dose azithromycin treatment of positive patients is the most cost-effective strategy when the prevalence is 6%. When the prevalence is lower than 6%, the decision to choose a competing strategy depends on the physician's view of the value of preventing an illness caused by untreated chlamydial infection.
