Methods. Between November 2005–August 2006, 300 married women were included. A questionnaire and vaginal discharge
assessment form were used for data collection. The modified algorithm of a symptomatic approach without speculum examination
was used to manage participants. Three diagnoses were made for each participant. The first diagnosis was made by the
research nurse using the vaginal discharge assessment form; the second diagnosis is the clinical diagnosis which was made after
the gynaecological examination by a physician; and the third diagnosis is the microscopic diagnosis made by the physician when
assessing the collected specimens.
