4. 39 Weeks Project – Timeline • August 2009: Webinar to orient teams to “lookback” data collection (50-chart review) • September 2009: Learning session for all teams (38) to review evidence, site-specific data and to develop goals/action plan • October 2009: Data collection began, sites beginning to test changes. Two additional teams joined. • December 2009: PQCNC annual meeting, half of teams attended and participated in “town meetings.” • January 2010: All-team webinar with national speakers • March 2010: Regional town meetings • August 2010: Final learning session • Late Fall 2010: Next maternal health collaborative begins

5. 39 Weeks Project – Data collection Data collected on every induction and scheduled c-section between 36w0d and 38w6d • Criteria for establishing gestational age • Cervical exam at admission (for inductions) • Mode of delivery • Maternal complications • Newborn complications • Respiratory support (anything beyond blow-by O2 in the delivery room) • NICU admission • Sepsis • Meconium aspiration syndrome • Transfer out • Death • Indication(s) for delivery and presence of objective data to support each indication The disclaimer: Please note that we do not endorse all of these as legitimate medical reasons for planned delivery. This list includes items that you may encounter as “indications for delivery.” You may ultimately decide in your hospital’s action plan not to allow some of these without a preceding amniocentesis to confirm gestational age if delivery is planned before 39 weeks.

7. Why 39 Weeks? • Joint Commission Perinatal Care Core Measures, effective April 2010: • Elective delivery < 39 weeks • Cesarean section for first-time, low-risk women • Use of antenatal steroids • Health care-associated blood stream infections • Exclusive breastfeeding at hospital discharge • NQF-endorsed voluntary consensus standard for hospital care • The Leapfrog Group perinatal care measure

8. C-section rates • In 2007 U.S. cesarean rate was 31.8%, a 54% increase since 1996. • North Carolina c-section rate was 31.2% in 2007 and 31.3% in 2008.

9. Induction of labor • In 1990, 9.5% of all US births started as inductions of labor • In 2006, 22.3% of all US births were inductions • Rate of increase of medically indicated inductions was lower than overall induction rate increase • Elective inductions are approximately 10% of all US deliveries

10. Fetal Lung MaturityACOG Practice Bulletin #97, August 2008 Fetal Lung MaturityACOG Practice Bulletin #107, August 2009Induction of Labor To prevent iatrogenic prematurity, fetal pulmonary maturity should be confirmed before scheduled delivery at less than 39 weeks of gestation unless fetal maturity can be inferred from any of the following historic criteria: • US at < 20 weeks confirms EGA of ≥39 weeks • FHT by Doppler >30 weeks or by fetoscope >20 weeks • 36 weeks since + pregnancy test

12. Timing of Elective Repeat Cesarean Delivery at Term and Neonatal OutcomesTita ATN, Landon MB, Spong CY, et al. New England Journal of Medicine; 360:111-120. January 2009 • Study of 24,077 repeat c-sections at term, 1999-2002 at 19 hospitals • 13,258 (55%) were elective repeat c-sections; of these, 35.8% were before 39 weeks gestation (6.3% at 37 weeks, 29.5% at 38 weeks) • Looked at neonatal outcomes • Primary outcome was a composite of neonatal death, respiratory distress syndrome, TTN, hypoglycemia, sepsis, NICU admission, NEC, hypoxic-ischemic encephalopathy, CPR, ventilator support, arterial pH below 7.0, 5-minute Apgar 3 or below, prolonged hospitalization (5 or more days).

13. Tita et al, NEJM 2009

14. Tita et al, NEJM 2009 • There was a statistically significant higher risk among neonates born at 38w4-6d vs. 39 weeks (51% of pre-39 week elective deliveries were at this EGA). The relative risk was 1.21 with CI 1.04-1.40. • Women who delivered before 39 weeks were more likely to be: • Older • Lower BMI • White • Privately insured • Had 1st or 2nd trimester U/S for dating

15. Neonatal and maternal outcomes associated with elective term deliveryClark SL, Miller DD, Belfort MA, et al. American Journal of Obstetrics & Gynecology; 200:156.e1-156.e4. February 2009 • Prospective observational study in 27 hospitals over 3 months in 2007 (n=17794) • Of term (>37 weeks) deliveries, 44% were planned. Of planned term deliveries, 71% were purely elective • 16% of all deliveries were elective induction at term; 9.6% of all deliveries were elective at 37-38 weeks, with about equal numbers of inductions and repeat C/S, and 121 primary elective C/S <39 weeks.

20. The patient’s voice • What is driving the increase in scheduled delivery before 39 weeks? • Maternal complications • Fetal complications • Patient request • Provider schedules • Employment issues • Deployment issues • Family availability • What else?

21. Women’s Perceptions Regarding the Safety of Births at Various Gestational AgesGoldenberg RL, McClure EM, Bhattacharya A, Groat T, Stahl. Obstetrics & Gynecology, 114: 1254-1258. December 2009. The gestational age respondents consider a baby full term (n=650).

22. Goldenberg et al, 2009 The gestational age respondents considered it safe to delivery a neonate.

23. What’s next? • 39 Weeks Project ends this summer • Focus on “spread” to other NC hospitals and maintenance at those who have decreased rate of electives <39 weeks • New initiative for 2011: increasing the rate of vaginal delivery among low-risk, first-time mothers at term (reducing the primary c-section rate)!
