Abstract
This study compares rates of trial of labor after Cesarean delivery TOLAC and rates of successful TOLAC between 1990 and 2009 Serial crosssectional analyses were performed using the National Hospital Discharge Survey data to compare rates of TOLAC and TOLAC success between 1990 and 2009 Joinpoint regression was used to assess trends over time and logistic regression with marginal effects was used to examine the unadjusted and adjusted significance and magnitude of trends The rate of TOLAC reached a high of 518 95 CI 478–558 in 1995 and a low of 159 95 CI 138–180 in 2006 declined on average 42 95 CI −48 to −39 percentage points per year between 1996 and 2005 Rates increased significantly from 1990 to 1996 and 2005 to 2009 TOLAC success was at its highest rate in 2000 698 95 CI 652–743 and its lowest in 2008 385 95 CI 281–488 The rate of TOLAC success increased significantly between 1990 and 2000 but declined thereafter an average of 34 points per year 95 CI −43 to −25 The rate of TOLAC in the US decreased between 1996 and 2005 and the rate of successful TOLAC has declined from 2000 to 2009
