  • Slide Set #1
  • This schematic gives an overview of the process for implementing a successful program to reduce or eliminate elective deliveries taking place before 39 weeks gestation. The patient and clinician are critical in reducing elective deliveries. This process must begin with educating not only the clinician, but also the patient as to why it is unsafe to deliver before 39 weeks unless there is a medical or obstetrical reason to do so. The hospital staff is also a key player in this process. In addition, a policy must be created and the medical leadership must be on board. The process will be a lot smoother and cause less angst amongst the hospital staff if they are not placed in a position of having to tell the physician they cannot schedule a delivery. In the event that there is a dispute, the staff must be empowered to refer the scheduling physician to medical leadership for resolution. Finally, in order to track progress, data must be collected and charts reviewed periodically to confirm progress.
  • Medically Indicated Deliveries Before 39 weeks

    1. 1. Medically Indicated Deliveries Before 39 Weeks Gestational Age “MIDB39 weeks” Chukwuma I. Onyeije, M.D. Atlanta Perinatal Associates 1
    2. 2. Research and Experience Show: Early ELECTIVE delivery without MEDICAL or OBSTETRICAL indication is linked to neonatal morbidities with NO benefit for the mother or infant. HOWEVER…. There are numerous maternal and fetal indications for deliveries BEFORE 39 weeks gestation ALSO… Elective deliveries AFTER 39 weeks are not necessarily without risks for mother and infant. 2
    3. 3. Is there really a problem here? “What’s the big deal?” “It’s only a couple of days?” “No one is going to tell me how to practice medicine.” Actual quotes from OBGYN providers regarding 39 week policy. Circa 2002. 3
    4. 4. Inductions of Labor • ACOG has cautioned against inductions before 39 weeks in the absence of a medical indication since 1979. (Committee Opinion #22) • ACOG also suggests that “a mature fetal lung maturity test result before 39 weeks of gestation, in the absence of appropriate clinical circumstances, is NOT an indication for delivery” (Committee Practice Bulletins #97 and #107) 4
    5. 5. How did we get here? 1992 To 2002 “The Lost Decade” 6

    10. 10. Why are Non-medically Indicated (Elective) Deliveries Increasing in Frequency?
    11. 11. Obstet Gynecol 2009;114:1254
    12. 12. The Gestational Age that Women Considered a Baby to be Full Term 29.1% 21.7% 20.8% 17.4% 3.3% Obstet Gynecol 2009;114:1254 3.3% 4.8%
    13. 13. The Gestational Age that Women Considered it Safe to Deliver 35% 31% 30% 25% 22% 19% Women's Responses 20% 15% 14% 10% Obstet Gynecol 2009;114:1254 5% 0% 7% 3% 4% Weeks of Gestation
    14. 14. Pressure on Obstetricians Reasons that physicians may resist elimination of elective deliveries < 39 weeks: •Physician Convenience • Guarantee attendance at birth (“co-dependency”) • Avoid scheduling conflicts • Reduce being awakened at night •…what’s the harm? • Bad outcomes are unrecognized and rare • The NICU handles these issues just fine •Limit risk of a bad pregnancy outcome Clin Obstet Gynecol 2006;49:698-704
    15. 15. Risks of Non-medically Indicated (Elective) Delivery Before 39 Weeks
    16. 16. Complications of Non-medically Indicated (Elective) Deliveries Between 37 and 39 Weeks • • • • • • Increased NICU admissions Increased transient tachypnea of the newborn (TTN) Increased respiratory distress syndrome (RDS) Increased ventilator support Increased suspected or proven sepsis Increased newborn feeding problems and other transition issues Clark 2009, Madar 1999, Morrison 1995, Sutton 2001, Hook 1997
    17. 17. QUESTION: WHO (EXACTLY) IS TERM? 18
    18. 18. OLD Terminology Late Preterm Early Term First day of LMP Week # 0 20 0/7 340/7 Preterm 37 0/7 39 0/7 Term 416/7 Post term Modified from Drawing courtesy of William Engle, MD, Indiana University Raju TNK. Pediatrics, 2006;118 1207. 19
    19. 19. NEW Terminology October 31, 2013 20
    20. 20. Term Pregnancy Redefined by ACOG and SMFM Published in the November 2013 Green Journal. Four new definitions of “term pregnancy” were issued by ACOG & SMFM in a joint Committee Opinion. Terminology designed to put the focus on preventing deliveries before 39 weeks’ gestation. 21
    21. 21. ACOG and SMFM now discourage the use of the general label “term pregnancy” Early Term: Between 37 weeks 0 days and 38 weeks 6 days Full Term: Between 39 weeks 0 days and 40 weeks 6 days Late Term: Between 41 weeks 0 days and 41 weeks 6 days Postterm: Between 42 weeks 0 days and beyond 22
    22. 22. Okay. How do I know if my patient is “Full Term”? 23
    23. 23. 24
    24. 24. Confirmation of Term Gestation • Early ultrasound (< 20 weeks gestation) is more accurate than an ultrasound after 20 weeks gestation at determining gestational age and benchmarking < 39 weeks gestation. • Ultrasound-established dates should take precedence over LMP-established dates when the discrepancy is greater than 7 days in the first trimester and 10 days in the second trimester… OR if the LMP-established dates are uncertain. 25
    25. 25. Actual Case: JT presented for prenatal care on 9/7/13 with an LMP of 2/19/13. She was assigned an EDD of 11/26/13 and an EGA of 28 weeks. Her first ultrasound on 9/25/13 showed an EFW which placed her fetus at < 10 %tile. Her second ultrasound on 10/28/13 showed an EFW which placed her fetus at < 10 %tile. 26
    26. 26. At the time of her second ultrasound the physician performing the ultrasound asked if she had had any previous ultrasounds. She pulled this out of her pocket from an emergency room visit on 5/23/13 (almost 5 months earlier) for spotting…… 27
    27. 27. Emergency Room Ultrasound Date performed: 5/23/13 CRL: 49.5 mm EGA: 11w5d 28
    28. 28. NEW EDD: 12/7/13 NEW EFW %tile: 54% 29

    33. 33. ACOG Committee Opinion: April 2013  The neonatal risks of late preterm and early-term births are well established.  HOWEVER, there are a number of complications in which either a late-preterm or early-term delivery is warranted.  The timing of delivery must balance the maternal and newborn risks of late-preterm and early-term delivery with the risks of further continuation of pregnancy. 34
    34. 34. ACOG Committee Opinion: April 2013 Decisions regarding timing of delivery must be individualized. Amniocentesis for the determination of fetal lung maturity in well-dated pregnancies generally should not be used to guide the timing of delivery. 35
    35. 35. Terminology Recall…. Early Term: Between 37 weeks 0 days and 38 weeks 6 days Full Term: Between 39 weeks 0 days and 40 weeks 6 days Late Term: Between 41 weeks 0 days and 41 weeks 6 days Postterm: Between 42 weeks 0 days and beyond 36
    36. 36. Terminology for Medically Indicated Deliveries Late Preterm Between 34 weeks 0 days and 36 weeks 6 days. Early Term: Between 37 weeks 0 days and 38 weeks 6 days Full Term: Between 39 weeks 0 days and 40 weeks 6 days Late Term: Between 41 weeks 0 days and 41 weeks 6 days Postterm: Between 42 weeks 0 days and beyond 37

    50. 50. Conclusion: Reasons to Eliminate Non-Medically Indicated (Elective) Deliveries Before 39 Weeks  Reduction of neonatal complications  No harm to mother if no medical or obstetrical indication for delivery  Strong support from ACOG  Now a national quality measure for hospital performance: - National Quality Forum (NQF) - Leapfrog Group - The Joint Commission (TJC) 52
