Vital Statistics Flashcards
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
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)
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
Birth Rate
The number of live births per 1000 population
Fertility Rate
The number of live births per 1000 females aged 15 through 44 years
Stillbirth or fetal death
the absence of signs of life at or after birth
Early neonatal death
death of a liveborn neonate during the first 7 days after birth
Late neonatal death
Death after 7 days but before 29 days
Stillbirth rate or fetal death rate
number of stillborn neonates per 1000 neonates born, including live births and stillbirths
Neonatal Mortality Rate
The number of neonatal deaths per 1000 live births
Perinatal Mortality Rate
The number of stillbirths plus neonatal deaths per 1000 total births
Infant death
All deaths of liveborn infants from birth through 12 months of age
Infant mortality rate
the number of infant deaths per 1000 live births
Low birthweight
A newborn whose weight is < 2500 g
Very low birthweight
A newborn whose weight is < 1500 g
