1

Maternal Mortality Rate

- an area that is audited worldwide as a quality of care measure
- Defined: The number of maternal deaths that result from the reproductive process per 100,000 live births

2

Perinatal Period

- Period after birth of an infant born after 20 weeks, and ending at 28 completed days after birth
- When perinatal rates are based on birthweight (BW), rather than gestational age (GA), it is recommended that perinatal period be defined as commencing at 500 grams (g)

3

Birth vs. Abortus

- Complete expulsion or extraction from the mother of a fetus after 20 weeks’ gestation


- Abortus – A fetus or embryo removed or expelled from the uterus during the first half of gestation – 20 weeks or less, or in the absence of accurate dating criteria, born weighing < 500 g

- In absence of accurate dating criteria, fetuses weighing <500 g are usually NOT considered births, but rather as abortuses for purposes of vital statistics

4

Birth Rate

The number of live births per 1000 population

5

Fertility Rate

The number of live births per 1000 females aged 15 through 44 years

6

Stillbirth or fetal death

the absence of signs of life at or after birth

7

Early neonatal death

death of a liveborn neonate during the first 7 days after birth

8

Late neonatal death

Death after 7 days but before 29 days

9

Stillbirth rate or fetal death rate

number of stillborn neonates per 1000 neonates born, including live births and stillbirths

10

Neonatal Mortality Rate

The number of neonatal deaths per 1000 live births

11

Perinatal Mortality Rate

The number of stillbirths plus neonatal deaths per 1000 total births

12

Infant death

All deaths of liveborn infants from birth through 12 months of age

13

Infant mortality rate

the number of infant deaths per 1000 live births

14

Low birthweight

A newborn whose weight is < 2500 g

15

Very low birthweight

A newborn whose weight is < 1500 g

16

Extremely low birthweight

A newborn whose weight is < 1000 g

17

Term neonate

A neonate born anytime after 37 completed weeks of gestation and up until 42 completed weeks (260 days to 294 days)

18

Preterm neonate

A neonate born before 37 completed weeks (the 259th day)

19

Postterm neonate

A neonate born anytime after completion of the 42nd week, beginning with day 295

20

Direct Maternal Death

death of the mother that results from obstetrical complications of pregnancy, labor, or the puerperium and from interventions, omissions, incorrect treatment, or a chain of events resulting from any of these factors

21

Indirect Maternal Death

Death results from previously existing disease or a disease developing during pregnancy, labor, or the puerperium that was aggravated by maternal physiological adaptation to pregnancy
- cause of death is caused a disease made worse by pregnancy

22

Nonmaternal death

Death of the mother that results from accidental or incidental causes not related to pregnancy

23

Causes of Maternal Deaths Worldwide

Hemorrhage – 24.8%
Sepsis – 14.9%
Hypertensive disorders – 12.9%
Unsafe abortion – 12.9%
Obstructed labor – 6.9%
Other causes – 27.6%
