BACKGROUND
Vaginal discharge is the commonly narrated compliant of the female attendees of sexually transmitted infection clinic, among which bacterial vaginosis (BV) is responsible for one-third of the visits. BV is often diagnosed clinically which warrants laboratory confirmation.
AIMS
The study aims to detect the reliability of the Nugent scoring system between observers for the diagnosis of BV.
MATERIALS AND METHODS
This is a prospective study including 177 high vaginal swabs. The gram-stained smears were examined by three independent microbiologists, and the Nugent scoring was performed. Statistical analysis was performed using IBM-SPSS version-22 statistical package for kappa value.
RESULTS
Concordant results were seen in 64.03% of smears, discordant results were given in 4.51% of smears, and partial agreement was observed in 31.63% of smears.
CONCLUSION
Interobserver reliability is good for the Nugent score. The Nugent score is a simple and reliable method for the diagnosis of BV that can be adapted even in the resource poor settings.
背景
阴道分泌物异常是性传播感染门诊女性就诊者常提及的症状，其中细菌性阴道病（BV）占就诊原因的三分之一。BV通常通过临床诊断，但需要实验室确诊。
目的
本研究旨在检测Nugent评分系统在不同观察者之间用于诊断BV的可靠性。
材料与方法
这是一项前瞻性研究，纳入177份高阴道拭子。革兰氏染色涂片由三名独立的微生物学家进行检查，并进行Nugent评分。使用IBM-SPSS 22版统计软件包对kappa值进行统计分析。
结果
64.03%的涂片结果一致，4.51%的涂片结果不一致，31.63%的涂片存在部分一致。
结论
Nugent评分在观察者间的可靠性良好。Nugent评分是一种简单可靠的BV诊断方法，即使在资源匮乏的环境中也可采用。
