Searching
We searched MEDLINE and HealthSTAR databases from 1980 to March 2002, with the help of an experienced medical librarian, using MeSH terms and text words including “vaginal birth after cesarean,” “cesarean,” “trial of labor/labour,” “trial of scar,” “vaginal delivery,” and “labor/labour.” Additional studies were identified by reviewing the reference lists of all included studies and review articles and through suggestions of national experts. Further details regarding search strategies used by
Results
Our search identified 3065 citations, of which 157 were potentially relevant. An additional 22 studies were identified from reference lists or expert suggestions, for 179 full-text articles. The reapplication of eligibility criteria resulted in the inclusion of 95 individual factor studies, 9 screening studies, and 5 studies of both individual factors and screening.
Eighty-eight were rated as poor quality for failing to control for confounding. In the end, 13 individual factor studies,14., 15.,
Comment
Cesarean deliveries in 2002 were at the highest level reported since 1989, whereas the rate of vaginal birth after previous cesarean delivery fell 55% from 1996 to 2002.2 In large part, the decrease in VBAC rates is reflective of concerns for the safety of VBAC after highly publicized reports of significant morbidity from failed trial of labor, most notably, cases of catastrophic uterine rupture. One of the goals of an obstetric provider is to accurately diagnose women who are at high risk for

The Association between Hospital Frequency of Labor after Cesarean and Outcomes in California
2020, Women's Health IssuesCitation Excerpt :Both LAC frequency and success are difficult to measure, and these estimates may have some variability. When LAC is attempted, success varies by clinical factors, including obstetric history and maternal weight, as well as hospital and physician characteristics (Dunsmoor-Su, Sammel, Stevens, Peipert, & Macones, 2003; Hashima, Eden, Osterweil, Nygren, & Guise, 2004; Macones et al., 2005; Marchiano, Elkousy, Stevens, Peipert, & Macones, 2004). In contrast with individual-level clinical factors, there is a relative evidence gap regarding the contribution of institutional factors to VBAC and other LAC outcomes.
Trial of labor after cesarean in older women who never delivered vaginally
2020, European Journal of Obstetrics and Gynecology and Reproductive BiologyCitation Excerpt :In addition, older women represent a small proportion in previous cohorts, and evaluating their chances of successful TOLAC is particularly challenging due to the lack of evidence-based data. Prior reports demonstrated that older women are less likely to undergo TOLAC and the VBAC rate is lower in those who do; this correlates directly with maternal age. [11,14,15,22,23] However, none of these studies specifically addressed older women who never delivered vaginally.
Application of predictive model for vaginal birth after caesarean delivery
2018, International Journal of Nursing SciencesCitation Excerpt :Amongst all the variables of the seven models above, prior VD had the highest frequency of occurrence, was consistently found by all models and associated with an increased likelihood of VBAC [5–7,16–19]. Women that had a prior VD had a 28-fold increase in the likelihood of VBAC compared with those without a prior VD [21,22]. The variable with the second highest frequency of occurrence was the timing of VD; women who had VD before caesarean delivery were 1.5–1.8 times more likely to have a VBAC compared with those without [15–17].
Vaginal birth after cesarean: clinical risk factors associated with adverse outcome
2008, American Journal of Obstetrics and GynecologyCitation Excerpt :In fact, only 7 conditions had VBAC success rates within the published range. These findings support work by other investigators arguing for identification of subsets of women most likely to do well with VBAC.12,14 Our findings raise several clinical points for consideration.
Temporal trends in the rates of trial of labor in low-risk pregnancies and their impact on the rates and success of vaginal birth after cesarean delivery
2006, American Journal of Obstetrics and GynecologyCitation Excerpt :We find this stability in success rate to be intriguing. A potential consequence of the decline in TOL attempts would be the improved selection of TOL candidates by physicians and an increase in success rates, because several algorithms have been devised and used to determine the predictive factors that are associated with successful TOLs.19-24 Unfortunately, our data are based on vital records, and we do not have access to the specific details that would be found in patient charts.
