BACKGROUND: Vaginal discharge syndrome (VDS) is a common clinical diagnosis during pregnancy in Botswana; it is treated with broad-spectrum antibiotics using a syndromic approach. We evaluated associations between the syndromic management of VDS and adverse birth outcomes. METHODS: The Tsepamo Study performs birth outcomes surveillance at government hospitals throughout Botswana. Obstetric record data collected from August 2014 to March 2019 were analyzed. Chi-square tests were conducted to compare proportions of maternal characteristics and infant outcomes. To avoid immortal time bias, all analyses were conducted among women who presented to care before 24 weeks gestation, with VDS categorized as present or absent by 24 weeks gestation. Log-binomial regression models were generated to determine associations between treated VDS and infant outcomes. RESULTS: VDS was diagnosed in 36 731 (30.7%) pregnant women, of whom 33 328 (90.7%) received antibiotics. Adjusted analyses yielded a harmful association between treated VDS and very preterm delivery (adjusted risk ratio, 1.11; 95% CI, 1.02–1.21). This association remained when restricting to women with VDS who received the recommended antibiotic treatment regimen. Sensitivity analyses produced nonsignificant associations when women with treated VDS were compared with women without VDS who received antibiotics for other indications. CONCLUSIONS: A clinical diagnosis of VDS is common among pregnant women in Botswana, and the majority receive antibiotics in pregnancy. Although analyses of VDS occurring later in pregnancy are precluded by immortal time bias, a modest association between treated VDS and very preterm delivery was observed among women diagnosed with VDS by 24 weeks gestation.
