[Decisional analysis in the diagnosis of Chlamydia trachomatis]

The aim of this work is the use of decisional analysis for the clinical diagnosis of Chlamydia trachomatis, to verify the utility of making a routine direct immunofluorescence test with a strategy of no routine direct immunofluorescence test with a strategy of no routine test in women during gynecologic escannations. Patients eligible for this analysis were sexually active woman, who are not pregnant, woman in reproductive age who do not have evidence of a clinical syndrome associated with or known to be caused by Chlamydia trachomatis. Our results show that the decision as to the use of the test involves 0.87 utility, while the decision of no routine test involves a 0.80 utility. We can therefore deduce that the best strategy for a woman who subjects herself to routine gynecologic care is to use this test, because the Chlamydia trachomatis has been implicated as the etiologic agent of acute salpingitis, chronic and tubal infertility.
