Five years to the term breech trial: the rise and fall
of a randomized controlled trial
Department of Obstetrics and Gynecology, Wolfson Medical
Center, The Helen Schneider Hospital for Women, Holon,
Israel.
Objectives:
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trial recommendations should be withdrawn.
