Accuracy of syndromic management in targeting vaginal and cervical infections among symptomatic women of reproductive age attending primary care clinics in Dakar, Senegal

摘要

Abstract Objective To assess the effectiveness of the WHO syndromic algorithm in the management of vaginal discharge among women of reproductive age in Dakar. Methods Cross‐sectional study of consecutive female patients (aged 18–49 years) presenting with vaginal symptoms at six selected study sites in Dakar; of these, 276 patients were included in the analysis. Vaginal and cervical swab samples were collected and analysed to establish an aetiological diagnosis of any infection. Syndrome‐based diagnosis was compared with the laboratory results to evaluate its accuracy based on sensitivity, specificity and positive and negative predictive values. The degree of agreement between the two approaches was assessed using the Cohen's kappa concordance analysis. Results Overall prevalence of vaginal infections was 56.9% (157/276); 5.4% (15/276) of the patients had cervical infection. Using the syndromic approach, 51% of patients were correctly managed for Trichomonas vaginalis ( TV )/ Gardnerella vaginalis ( GV ); 61% for Candida albicans ( CA ) and 54% for Chlamydia trachomatis ( CT )/ Neisseria gonorrhoea ( NG ) infections. Consequently, 31% of patients with TV / GV , 51% with CA and 53% with CT / NG infections would have missed treatment. Further, the kappa value was 0.20, indicating that there was no agreement or only slight agreement between the syndromic approach and laboratory‐based diagnosis. Conclusion This study highlights the limitations of the applicability of the WHO syndromic approach in settings with low prevalence of sexually transmitted infections ( STI s) and calls for affordable and accurate rapid tests for STI s.
