FINAL DRAFT
Colorado Perinatal Care Council:
Position Paper on Elective Delivery
The Colorado Perinatal Care Council (CPCC) supports perinatal care practices that promote the
best possible health outcomes for mothers and newborns. In recent years, the number of
scheduled deliveries for non-medical reasons for mother or baby, either through induction of
labor or scheduled cesarean section, has increased.
Numerous studies show increased morbidity and mortality for the newborn when elective
deliveries occur before 39 completed weeks of gestation. Late-preterm infants (born between 3436 6/7 weeks gestation)1 are at increased risk2 for adverse health and developmental outcomes
that include: 1) respiratory distress syndrome (RDS) due to surfactant deficiency,3-14 2) need for
mechanical ventilation primarily due to RDS,4,9,10,12,14 3) sepsis/sepsis evaluation,7,8,14 4)
hypoglycemia,7,8,14 5) hyperbilirubinemia/ jaundice,7,8,15 6) feeding problems,7,8,16 7) apnea7,8,16
8) temperature instability8,16, 9) admission to the neonatal ICU14, 10) hospitalization (for 5 days
or more at birth,14,17 11) re-hospitalizations in the first month and first year of life,10,17,18 and 12)
long-term neurologic and developmental delays and complications requiring physical,
occupational and speech therapy and special education.9,19,20 These risks increase progressively
as gestational age at birth declines.3,6,10-14,18
All causes of infant mortality (birth defects, sudden infant death syndrome, respiratory distress
syndrome) in the US have decreased, except for prematurity which has actually increased.
Mortality rates for late-preterm infants are higher (8.9 to 9.2/100,000 live births) than for full
term infants (2.5/100,000 live births).21 A recent study comparing death rates of term and latepreterm infants found that late-preterm infant mortality rates were threefold higher than term
infants (7.9 versus 2.4 deaths /1000 live births).22
The Institute for Healthcare Improvement (IHI) has recommended a process improvement
approach that will help to decrease neonatal morbidity and mortality.23 Through the IHI
initiative, a combination of experts and front-line practitioners have identified processes that they
believe will decrease the risk of birth trauma and other adverse events. Based on the best
available evidence and science, the process uses the theory that if the science is right and the
related processes are carried out consistently, the outcomes will improve. They have developed
a “bundle” approach that is driven by processes that, when executed together, result in better
outcomes than when implemented individually.23

The Idealized Design of Perinatal Care includes an Elective Induction Bundle (www.ihi.org)
consisting of four components that support an evidence based approach to achieving improved
neonatal outcomes.23 The first component is gestational age 39 weeks or greater. Determination
of gestational age is defined in American College of Obstetricians and Gyneocologists’(ACOG)
Practice Bulletin #107 – “Induction of Labor”.24 While this bundle is aimed at elective
inductions, the same principle of delivery at 39 weeks or greater should be applied to elective
cesarean section as well.
The cesarean section rate in the United States in 2006 was 31.1% and continues to increase.25
Determining what proportion of this increase is attributable to elective cesarean section is
difficult. An international estimate of the elective cesarean section rate ranges between 4% and
18% .25 A portion of elective cesarean sections are performed because they are requested by the
patient. Some women request a cesarean section to avoid potential physical consequences after
vaginal delivery, such as possible urinary and anal incontinence and pelvic organ prolapse.
According to the National Institute of Health (NIH) (http://consensus.nih.gov), there is little
significant evidence to associate these concerns with any particular mode of delivery.26 The lack
of public awareness can be a contributing factor in maternal requests for cesarean section.
ACOG (www.acog.org) supports a patient’s request for elective cesarean section along with
appropriate discussions of benefits and risks. ACOG does not recommend Cesarean Delivery on
Maternal Request for women desiring several children due to increased risks of placenta previa,
placenta accreta and hysterectomy. It is important that care providers assure that patients have all
the information about the risks, benefits and alternatives of elective cesarean section, ensuring
that the final decision is a collaborative effort.27 It is also important to follow the IHI’s
recommendation that elective delivery not occur prior to 39 completed weeks of gestation. Care
providers need to be fully informed about these factors and need to assure that their patients are
well informed about the risks as well.
Colorado Perinatal Care Council Recommendations:
1. All care providers must be fully informed of both the maternal and neonatal risk
factors involved in scheduled delivery.
2. Electively scheduled delivery (whether induction or cesarean section) should only
occur when the patient has reached 39 completed weeks of gestation or greater. It is
important to emphasize that medical indications such as hypertension/ preeclampsia, previous uterine surgery including classical Cesarean section,

intrauterine growth restriction, diabetes, advanced cervical dilation, history of rapid
labor, living far away from a hospital, and other pregnancy complications do justify
early delivery for the well-being of mother and/ or baby.
3. Assure that all patients are fully informed about elective delivery and the risks of
delivery occurring prior to 39 completed weeks of gestation. The March of Dimes
pamphlet, Why the Last Weeks of Pregnancy Count and the Late-Preterm Brain
Development Card, provide excellent patient information and can be utilized for
patient education.
4. Utilize the ACOG criteria (ACOG Practice Bulletin #107) to determine gestational
age.
5. The decision to have an electively scheduled delivery should be a collaborative
decision between a fully informed patient and her care provider.
6. Documentation of informed consent should be present in the medical record.
7. Apply the four criteria in the IHI bundle for Elective Induction if the patient is
induced.
8. Document that all criteria have been met when the procedure is scheduled.
