MFMU Network Study- NEJM 2009 Observational cohort including 19 different hospitals and 24,000 patients 35.8% of the elective Cesarean deliveries were performed before 39 weeks – infants delivered at 38 weeks had a 1.5x greater chance of being admitted to NICU – infants delivered at 37 had a 2x greater chance of being admitted to NICU – gestational age with the lowest risk for neonatal complications was 40 weeks.

Timing of Fetal Brain Development Cortex volume increases by 50% between 34 and 40 weeks gestation. Brain volume increases at rate of 15 mL/week between 29 and 41 weeks gestation. A 5-fold increase in myelinated white matter occurs between wks gestation. Frontal lobes are the last to develop, therefore the most vulnerable.

Oklahoma Experience A number of hospitals already low rates of nonmedically indicated early deliveries Many hospitals have implemented successful programs Some hospitals still have high rates of nonmedically indicated delivery

ACOG Practice Bulletin Labor also may be induced for logistic reasons, for example, risk of rapid labor, distance from hospital, or psychosocial indications. In such circumstances, at least one of the gestational age criteria in the box should be met, or fetal lung maturity should be established. A mature fetal lung test result before 39 weeks of gestation, in the absence of appropriate clinical circumstances, is not an indication for delivery.

From the Trenches That’s not how my babies do This is an “overly restrictive policy” It’s really a medical indication No, really, she’s 39+ weeks It’s not an induction, it’s an augmentation

That’s not how my babies do First, the majority of deliveries occurring between 38 and 39 weeks of gestation do not result in harm. The absolute number of newborn respiratory complications is low. If an obstetrician performs 200 deliveries a year and 10% of his or her patients are electively delivered at 38 weeks of gestation, only one neonate would be admitted to the NICU per year.

This is an overly restrictive policy Protocols and strong guidelines are used extensively in Internal Medicine and Surgery Door-to-cath times, use of ASA and β-blockers Pre-operative antibiotics and VTE prevention Stroke: very strict protocols Publicly reported, payment-based standards OB has been “below the radar” Movement has now been taken up by commercial insurers and Medicaid

It’s really a medical indication Edema Impending macrosomia

Spong, CY et al; Obstet Gynecol 2011;118:

Really, she’s 39+ weeks Induction not approved due to GA < 39 weeks with no medical indication Pregnancy dated by LMP consistent with 10 week CRL 34 week ultrasound showed EFW at 75 th percentile and CGA was 2 weeks further along – New posting sheet sent with “revised” EDD

It’s not an induction, … augmentation

Quality Marker The Joint Commission, CMS, Agency for Healthcare Research and Quality, National Quality Forum, and many insurers have listed NMI early term deliveries as a perinatal quality measure.

How Do You Measure Elective Deliveries <39 weeks? (The Joint Commission Measure Definition) TJC (PC-01) v2011A (latest for 2011) Denominator37+0 to 38+6 week births without a STANDARD medical or OB complication NumeratorInductions and CS NOT in Active Labor or with ROM Benchmark?? <5-6%

These are not exhaustive lists! But close… (e.g. prior classical CS)

Caveats about the Indication List The Joint Commission list was developed for ease of data collection utilizing ICD-9 codes. If there is not an ICD-9 code for an indication, they did not list it (e.g. prior classical CS). Everyone understands that there are cases in which earlier delivery is indicated and but the indication is NOT on the list—but these should be uncommon. No one is expecting a ZERO rate. Off-list indications should be prospectively scrutinized

HB 1983 Effective Oct 1, Texas Medicaid will require providers to use CPT modifier for deliveries less than 39 weeks Texas Medicaid is be able to recoup payment from hospital and doctor for any NMI deliveries < 39 wks – No time limit – Potential fraud if bill for NMI delivery

Summary 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)

What is the Real Importance Here? There will continue to be research and technology innovations, and changes in best practice that need to be implemented Physician leadership and collaboration with nursing and hospital administration is essential
