 Maternal death review dates to 1928 in Virginia.
 Collaboration between the Medical Society of
Virginia and Virginia Department of Health.
 Early reviews focused on medical issues and
natural deaths.
 Lack of funding and support: review activities
declined in 1990s.
2
 Throughout the 1900’s, the maternal mortality rate
declined significantly:
 Principles of asepsis were instituted
 Shift from home to hospital deliveries
 Institutional practice guidelines and guidelines defining physician
qualifications for hospital delivery privileges
 Use of antibiotics
 Safer blood transfusions
 Better management of hypertensive disorders of pregnancy

“Healthier Mothers and Babies” as measured by the
decline in infant mortality and maternal mortality
was considered to be one of the “Ten Great Public
Health Achievements in the US, 1900-1999”*

 US ranks 31st among other developed countries in maternal
mortality. ( Virginia ranks 17th in the US.1)
 US population has maternal mortality rates substantially lower
in some racial/ethnic subgroups with no definable biologic
reason to indicate an irreducible minimum has been reached.

Pregnancy-Associated Maternal Death:
All deaths of women occurring during
pregnancy or within one year of termination
of pregnancy.
 Regardless of cause of death.
 Regardless of outcome of pregnancy.
10
1.
Was this death pregnancy related?
2.
Was this death preventable?
3.
What factors contributed to the death and what
reasonable changes could have been made to
alter the outcome?
11
Preventable death is broadly defined as a death
that may have been averted by one or more
changes in:
clinical care
facility infrastructure
community
systems response to patient factors
These determinations were made with the benefit
of retrospective review and current clinical
practice guidelines.
12
As each case was reviewed, the Team
identified factors within those four
categories that contributed to death
in that case.
13
 After review of the first 4 years of cases, the Team looked at
the findings and identified a major risk factor for
pregnancy-associated death in Virginia:
Obesity
 The Team published, “Obesity and Maternal Death in
Virginia, 1999-2002” in March of 2009.

15
Increased risk for hypertension
Increased risk for Type 2 diabetes
Increased risk for heart disease
Increased risk for certain cancers
(Nearly ½ of all
endometrial or uterine cancers are believed to be caused by excess
body fat.)
Increased risk for pregnancy complications
such as pre-eclampsia which are associated
with morbidity later in life

 137 women died from natural causes while
pregnant or within one year of a pregnancy in
Virginia during the review period, 1999-2004.
 102 (74.4%) of those cases had both height and
prepregnancy weights listed in the record from
which prenatal BMI was calculated and are
included in this report.
18
 Prepregnancy BMI ranged from 16.3 to 58.5
 Average BMI was 29.96 (30.0 = Obese)
 5 deaths were to underweight women
 32 deaths were to normal weight women
 24 deaths were to overweight women
 41 deaths were to obese women


Two women classified as overweight were
pregnant at the time of death and died from
cardiac disorders. There was one stillbirth.

Among the obese women, there was one
miscarriage, one ectopic pregnancy and five
losses due to the mother’s death.
 Fetal losses resulted from the mother’s
death due to pulmonary embolism,
cancer, cardiac arrest or arrhythmia.
28
 38.4% had at least one miscarriage prior to the most
recent pregnancy
 23.1% had a previous pregnancy complication such as
gestational hypertension, preeclampsia, p0st partum
hemorrhage, hyperemesis gravidarum, preterm labor.
 10.8% had gestational diabetes in this or a prior
pregnancy
29
 35.4% died within one week of delivery with an
additional 9.3% dying before six weeks post partum.
 64.0% of the deaths of overweight and obese women
were determined by the Maternal Mortality Review
Team to be directly related to the pregnancy.
 31.2% were thought to be preventable with reasonable
systems changes.
30
•
All providers should educate patients about the
adverse physical effects of being overweight and
obese especially during pregnancy.
•
Providers of pregnancy-related services should
promote the use of WIC by disseminating a
description of the program and eligibility
requirements to all pregnant women and new
mothers.
31
 All healthcare providers should be informed about the
specialized level of care needed for obese pregnant
patients. Emphasis should be placed on:
 preconception counseling for all women on the risks
associated with obesity and pregnancy;
 identification of obesity as a diagnosis in and of
itself requiring supplemental testing or consult for
care.
32

All schools in Virginia should participate in the
Governor’s Nutrition and Physical Activity Scorecard
which provides incentives to schools for implementing
research based best practices supporting proper
nutrition and increased physical activity.

All employers should provide a health improvement
program to employees which includes weight
management strategies.

Third party payers should provide coverage for dietary
counseling, education, and nutrition therapy for
individuals with BMIs greater than 30.0.
