Background: In 2010, the American Congress of Obstetricians and Gynecologists (ACOG) released new clinical guidelines on vaginal birth after cesarean (VBAC).  This presentation analyzes and illustrates, through mapping, trends in VBAC rates at the state and county level before and after the dissemination of new guidelines.  

Methods: NCHS national birth certificate data was used. Mode of delivery was assessed at the state and country level for 2009 and 2011.  Adjustments were made to account for the number of states that had adopted the 2003 revision to the Standard Certificate of a Live Birth.  The 40 states (12 retaining the pre-2003 certificate and 28 with the 2003 revision) which didn’t change their birth certificate between 2009-2011 are the focus of the analysis.  Multivariate analysis assesses the extent of change 2009-2011 controlling for state economic and health characteristics.

Results: Preliminary analysis found 37 of the 40 states experienced an increase from 2009-2011, though the increase was < 2 percentage points in 33 states. Delaware experienced the largest increase (8% to 12%). States reported wide variation in VBAC rates in 2011. Colorado (19.6%) and Utah (19.0%) reported the highest rates with Alabama (3.5%) and Mississippi (2.8%) the lowest.  Greater variation was seen at the county level in 2011 with St. Louis, MO (35%)  and Sante Fe, NM (33%) reporting the highest VBAC rates with 29 counties less than 3%.

Conclusion: Almost all states reported a slight increase in VBAC rates after the new guidelines, though there was wide variation across states and counties.
