The infamous Term Breech Trial (tinyurl.com/brgrm), published in 2000, claimed that planned cesarean was safer for breech babies than vaginal delivery. Now, the American Journal of Obstetrics and Gynecology has published a stinging critique that concludes the original study was deeply flawed and its conclusions unsupportable (Glezerman M, Five years to the term breech trial: The rise and fall of a randomized controlled trial. Amer J Ob & Gyn (2006) 194, 20-5). The article thoroughly itemizes the methodological flaws and clinical problems with the Term Breech Trial.
Five years to the term breech trial: The rise and fall of a randomized controlled trial.
American Journal of Obstetrics & Gynecology. 194(1):20-25, January 2006.
Glezerman, Marek MD
Objective: On the basis of the end points of neonatal morbidity and death, the authors of the term breech trial concluded unequivocally that cesarean delivery was safer for breech babies.
Study design: Analysis of the original and new data gives rise to serious concerns as far as study design, methods, and conclusions are concerned. In a substantial number of cases, there was a lack of adherence to the inclusion criteria. There was a large interinstitutional variation of standard of care; inadequate methods of antepartum and intrapartum fetal assessment were used, and a large proportion of women were recruited during active labor. In many instances of planned vaginal delivery, there was no attendance of a clinician with adequate expertise.
Results: Most cases of neonatal death and morbidity in the term breech trial cannot be attributed to the mode of delivery. Moreover, analysis of outcome after 2 years has shown no difference between vaginal and abdominal deliveries of breech babies.
Conclusion: The original term breech trial recommendations should be withdrawn.
