SECONDARY outcome

Timeframe: At index birth; Medicaid claims

Our original prenatal screening outcome variable included the obstetric panel: Rhesus-D (DRh), red blood cell (RBC) antibody screen, complete blood count (CBC), urine culture, urinalysis; sexually transmitted infection (STI) screenings (HIV, syphilis, hepatitis B, chlamydia if \<25, gonorrhea if \<25); Group B strep screening, and glucose screening. However, since most participants had already completed their first prenatal visit prior to enrolling in the trial (when many of these tests are performed), it was not appropriate to include first-visit tests as outcomes. We therefore modified the outcome to instead use three clinically relevant measures that could occur after enrollment: glucose screening, Group B strep screening, and Tdap vaccination. These outcomes are reported as they appear in the published papers.
