Registrar experience in vaginal breech delivery. How much is occurring?

The Changing Scenario of Obstetrics and Gynecology Residency Training

BACKGROUND

Significant changes have been noted in aspects of obstetrics-gynecology (ob-gyn) training over the last decade, which is reflected in Accreditation Council for Graduate Medical Education (ACGME) operative case logs for graduating ob-gyn residents.

OBJECTIVE

We sought to understand the changing trends of ob-gyn residents' experience in obstetric procedures over the past 11 years.

METHODS

We analyzed national ACGME procedure logs for all obstetric procedures recorded by 12 728 ob-gyn residents who graduated between academic years 2002-2003 and 2012-2013.

RESULTS

The average number of cesarean sections per resident increased from 191.8 in 2002-2003 to 233.4 in 2012-2013 (17%; P < .001; 95% CI -47.769 to -35.431), the number of vaginal deliveries declined from 320.8 to 261 (18.6%; P < .001; 95% CI 38.842-56.35), the number of forceps deliveries declined from 23.8 to 8.4 (64.7%; P < .001; 95% CI 14.061-16.739), and the number of vacuum deliveries declined from 23.8 to 17.6 (26%; P < .001; 95% CI 5.043-7.357). Between 2002-2003 and 2007-2008, amniocentesis decreased from 18.5 to 11 (P < .001, 95% CI 6.298-8.702), and multifetal vaginal deliveries increased from 10.8 to 14 (P < .001, 95% CI -3.895 to -2.505). Both were not included in ACGME reporting after 2008.

CONCLUSIONS

Ob-gyn residents' training experience changed substantially over the past decade. ACGME obstetric logs demonstrated decreases in volume of vaginal, forceps, and vacuum deliveries, and increases in cesarean and multifetal deliveries. Change in experience may require use of innovative strategies to help improve residents' basic obstetric skills.

Obstetric Trainees’ Experience in Vaginal Breech Delivery

OBJECTIVE

To determine whether trainee obstetricians intend to offer vaginal breech delivery once they become certified as specialists and to quantify their experience in vaginal breech delivery.

METHODS

This was an anonymous postal survey of all Australian trainee obstetricians. The survey inquired about experience with, confidence in, and intentions regarding planned vaginal breech delivery after trainees' certification as specialists.

RESULTS

Surveys were sent to all 303 Australian registered trainee obstetricians. The response rate was 65%. Experience in vaginal breech delivery increased with year of training, from a median of one delivery for first-year trainees to a median of 12 deliveries for final-year trainees. Although 53% of final-year trainees reported feeling confident with vaginal breech delivery, only 11% reported an intention to offer planned vaginal breech delivery at term as a specialist.

CONCLUSION

Few of the next generation of specialist obstetricians plan to offer vaginal breech delivery to their patients.

Breech vaginal delivery at or near term

Three percent to 4% of term fetuses will be breech at delivery. Evidence from randomized controlled trials has found a policy of planned cesarean section to be significantly better for the singleton fetus in breech presentation at term compared to a policy of planned vaginal birth. However, some women may wish to avoid cesarean section and for others, cesarean section may not be possible. We undertook this review to identify factors associated with higher and lower risk of adverse fetal or neonatal outcome at term during vaginal breech delivery. We searched MEDLINE from 1966 to 2002 using the search terms vaginal breech delivery and breech presentation and retrieved all relevant articles. We also reviewed personal references and reference lists of articles retrieved. Women who are older or who have a fetus that is either in footling presentation, has a hyperextended head or is estimated to weigh <2500 g or >4000 g may be at higher risk of adverse fetal outcome. Prolonged labor or not having an experienced clinician at vaginal breech birth may also increase the risk. Women with a fetus in breech presentation at term should be offered the option of delivery by planned cesarean section and should be informed that this will reduce their risk of adverse fetal or neonatal outcome. Practitioners should develop and maintain skills at vaginal breech delivery for those women not wishing or not able to be delivered by cesarean section.
