Introduction: Vaginal discharge is the most common complaint with which women of reproductive age group present to the gynecological outpatient. WHO syndromic approach algorithm helps in identifying the etiology based on the gross appearance of discharge but it often fails to detect the etiology correctly. Addition of simple microbiological tests helps to diagnose the etiology accurately.
Objective: To compare the diagnosis of symptomatic vaginal discharge based on WHO syndromic algorithm and microbiological tests.
Materials and Methods: 100 Women in the age group of 18 to 45 years with symptomatic vaginal discharge attending the gynecological OPD of Apollo Institute of Medical Science and Research, Hyderabad were examined in the outpatient and a clinical diagnosis made using WHO syndromic algorithm for vaginal discharge. Under aseptic precautions, vaginal discharge was collected and subjected to simple lab tests such as Gram’s stain and direct microscopy (wet mount). The lab results were compared with the clinical diagnosis.
Results: Among 100 women, bacterial vaginoses was the most common diagnosis. In 55% of patients etiological agent could be identified by lab investigations. By WHO syndromic approach, bacterial vaginosis was over diagnosed (70 vs. 44 cases confirmed by lab) and candidiasis was slightly under diagnosed (8 vs. 10 cases by lab). The sensitivity of WHO syndromic approach in diagnosing bacterial vaginosis is 100% while specificity is only 53%. The difference in diagnosis rate of candidiasis clinical versus microbiological diagnosis was marginal (10% vs. 11%). Trichomoniasis was accurately diagnosed by WHO syndromic approach.
Conclusions: WHO syndromic algorithm for vaginal discharge over diagnoses bacterial vaginosis but has a high sensitivity and specificity in diagnosing candidiasis and trichomoniasis. Simple microbiological test such as Gram stain and wetmount will increase the accuracy in diagnosis thereby preventing overtreatment.
