Project Overview
Health services research (HSR) informs policy implementation
Policy makers increasingly rely on HSR as an evaluation of the United States health care system1

Project Overview
Target Policy: timing of elective deliveries, or Non- Medically Indicated Deliveries (NMI).
NMI: Induction of labor or Cesarean Delivery without an accepted medical or obstetrical indication before the spontaneous onset of labor or rupture of membranes.1

American College of Obstetricians & Gynecologists (ACOG) recommendation: perform elective deliveries after 39 completed weeks gestation
WHY? Increased neonatal morbidity (respiratory
distress) and maternal complications for elective deliveries <39 weeks1
Elective deliveries <39wks US & account for 10-15%
of all deliveries despite ACOG recommendations.2

Reasons for Early Elective Inductions
Social factors Military deployment (Father)
Mother lives far away
Maternal intolerance of late Pregnancy, “Tired of being pregnant” Excess Edema, backache, indigestion,
insomnia

Objective
To determine the prevalence of US hospital-level
policy that specifically addresses non-medically indicated(NMI) delivery <39 weeks

Significance
Clinically: perinatal safety & quality
Nationally: Organizations*
developing a quality improvement toolkit
Need for policy reinforcement
* March of Dimes, California Maternal Quality Care Collaborative (CMQCC), and the California Department of Health, Maternal Child and Adolescent Health Division have collaborated on the development of a quality improvement toolkit: Elimination of Non-medically Indicated (Elective) Deliveries Before 39 Weeks Gestational Age
Archives of Surgery 145(2): 179-186, 2010

Methods
Telephone interview with either the Charge Nurse or Nurse Manager for all Labor and Delivery units listed in the AHA 2006 Master File.
N = 2,646 Hospitals
Interviewed consisted of two questions: Hospital Policy? Y/N Type of Policy?
Data was recorded in secure spreadsheet.

Methods
Independent review of responses by two practicing Obstetricians
Coding: o Y/N/ND o Hard Stop or Other (includes Soft Stop)
