Brief summary
The purpose of this investigator-initiated randomized control trial is to determine if bacterial vaginosis infection increases the likelihood of preterm delivery in women with history of preterm delivery. Subjects will be randomized in a two-arm study to undergo predetermined intervals of testing for bacterial vaginosis or control.
Detailed description
Preterm delivery affects 10% of all pregnancies in the United States. This risk is further increased in pregnant women with a history of preterm delivery. There are multiple etiology contributing of preterm labor. Of these, the presence of inflammation and infection have been a well-established cause. Bacterial vaginosis (BV), a common vaginal infection in pregnancy, may often be asymptomatic. Studies demonstrate a strong association between BV and preterm labor. Therefore it is recommended that women at high risk for preterm delivery are treated for this infection irregardless of symptoms. In this study the investigators hypothesize that increased testing for bacterial vaginosis, with subsequent timely treatment, may decrease the risk of preterm delivery in patients who are at high risk. The investigators suspect that the increase in monitoring will help diagnose asymptomatic bacterial vaginosis infections allowing for prompt treatment and avoidance of preterm labor. Subjects will be randomized in a two-arm study to undergo predetermined intervals of testing for bacterial vaginosis or control. No experimental drugs or devices will be used. * The intervention-arm will have a pelvic exam performed with vaginal swab collection at their initial obstetric visit. The women undergoing the intervention will then subsequently undergo additional vaginal swab collections in 2 week intervals starting at 16 weeks gestational age until 34 weeks gestational age. * The control arm will undergo the standard of care. There will be no placebo for the control group.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Number of participants with premature delivery (before 37 weeks gestation) | At delivery |
Other
| Measure | Time frame | Description |
|---|---|---|
| Length of hospital stay of mothers | Number of hours between time of admission to time of discharge, up to 4 weeks from time of admission | The length of hospital stay for mothers will be measured in hours from the time of admission to labor and delivery unit to the time of discharge from the post-partum unit. |
| Length of hospital stay of neonates | Number of hours between time of admission (birth) to time of discharge, up to 1 year from time of admission (birth) | The length of hospital stay for neonates will be measured in hours from the time of admission (birth) to discharge from the postpartum unit or neonatal intensive care unit |
