BACKGROUND: Botswana updated its antiretroviral treatment (ART) guidelines in May 2016 to support breastfeeding for women living with HIV (WLHIV) on ART who have documented HIV RNA suppression during pregnancy. METHODS: From September 2016 to March 2019, we evaluated feeding method at discharge among WLHIV at eight government maternity wards in Botswana within the Tsepamo Study. We validated the recorded feeding method on the obstetric record using the prevention of mother-to-child transmission of HIV (PMTCT) counsellor report, infant formula dispensing log or through direct observation. Available HIV RNA results were recorded from the obstetric record, and from outpatient HIV records (starting February 2018). In a subset of participants, we used electronic laboratory records to verify whether an HIV RNA test had occurred. Univariable and multivariable logistic regression analyses were performed to identify factors associated with infant feeding choice. RESULTS: Among 13,354 WLHIV who had a validated feeding method at discharge, 5303 (39.7%) chose to breastfeed and 8051 (60.3%) chose to formula feed. Women who had a documented HIV RNA result in the obstetric record available to healthcare providers at delivery were more likely to breastfeed (50.8%) compared to women who did not have a documented HIV RNA result (35.4%) (aOR 0.59; 95% CI 0.54, 0.65). Among women with documented HIV RNA, 2711 (94.6%) were virally suppressed ( 400 copies/mL, and 134 (27.4%) of 489 women with no reported ART use. A sub-analysis of electronic laboratory records among 150 women without a recorded result on the obstetric record revealed that 93 (62%) women had an HIV RNA test during pregnancy. CONCLUSIONS: In a setting of long-standing use of suppressive ART, with majority of WLHIV on ART from the time of conception, requiring documentation of HIV RNA suppression in the obstetric ...

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.
