Medi-Cal Payer

This refers to any birth record indicating that Medi-Cal or Medicare paid for labor and delivery. Note that Medi-Cal is the name of the federal Medicaid program in California.

No high school degree

The birth certificate includes information on the number of years of education completed by the mother. As a conservative estimate of the percent of mothers with no high school degree, the California County Profile Reports use the percent of mothers who completed 11 or less years of schooling.

Mexico-born mother

Mexico-born mothers are determined from the "birthplace of mother." This refers to foreign born mothers, specifically from Mexico.

Grand multiparity

Grand multiparous mothers are women who have had six or more births (including the current birth). Note that fetal deaths are included in the count of previous births.

Short birth interval

The birth certificate collects information on the months between the current and the previous birth. The previous birth can be a live birth or fetal death. A birth interval is considered short if the number of months between the current and last birth is 23 or less. Note that this calculation leads to a conservative estimate of the percent of births occurring within 24 months of a previous birth as births occurring in the 24th month are not included.

Late entry into prenatal care

A woman is considered to enter prenatal care late if her first prenatal visit occurs after the first trimester of pregnancy.

Inadequate prenatal care

The Adequacy of Prenatal Care Index (APNCU or Kotelchuck index) is based on two independent components: the initiation (timing) of prenatal care and the number of prenatal visits adjusted for the length of gestation. A woman is considered to have experienced inadequate prenatal care if the APNCU index (Kotelchuck index) indicates late or intermediate and/or too few prenatal care visits for the length of gestation.

Neonatal mortality rate

The neonatal mortality rate is defined as the number of deaths at less than 28 days of age divided by the number of all live births multiplied by 1,000. Live births with a birth weight of less than 500 grams are excluded.

Perinatal mortality rate

The Healthy People 2010 Objectives define perinatal deaths as fetal deaths at 28 weeks or more of gestation or deaths until 7 days of age. In the California County Profile Reports all live births and fetal deaths with birth weights of less than 500 grams are excluded. For the California County Profile Reports, the perinatal mortality rate is defined as the number of fetal or neonatal deaths at 28 weeks of gestation to seven days after birth with a birth weight of 500 grams or more divided by the number of all births at 28 weeks of gestation or more and with a birth weight of at least 500 grams multiplied by 1,000.

Postneonatal mortality rate

The postneonatal mortality rate is defined as the number of deaths at age 28 days to 365 days of age divided by the number of all live births that survived to 27 days of age multiplied by 1,000. Live births with a birth weight of less than 500 grams are excluded.

Infant mortality rate

The infant mortality rate is defined as the number of deaths within 365 days of age divided by the number of all live births multiplied by 1,000. Live births with a birth weight of less than 500 grams are excluded. Neonatal and postneonatal deaths combined constitute infant deaths.

Low birth weight

A baby is defined as having a low birth weight if its weight is less than 2,500 grams at delivery. For the compilation of the California County Profile Reports babies with birth weights less than 500 grams were excluded.

Very low birth weight

A baby is defined as having very low birth weight if its weight is less than 1,500 grams at delivery. Note that very low birth weight births are by definition also low birth weight births and counted in both birth weight measures. For the compilation of the California County Profile Reports babies with birth weights less than 500 grams were excluded.

Non-normal newborns

This information is derived from the California Patient Discharge Data (PDD) published by the California Office of Statewide Planning and Development (OSHPD). Diagnosis related groups (DRG) are case mix assignments grouping hospital patients to categories based on diagnostic, therapeutic, and demographic characteristics for the purpose of reimbursement. Each newborn is assigned to one of seven DRG codes:

DRG	Description
385	Died/Transferred
386	Extreme Immaturity/Respiratory Distress Syndrome
387	Prematurity with Major Problems
388	Prematurity without Major Problems
389	Full Term Neonate with Major Problems
390	Full Term Neonate with Significant Problems
391	Normal Newborn

For the California County Profile Reports, all newborns that died/transferred, were born prematurely, or were born full term but with major or significant problems were included in the group of non-normal newborns.

Long length of stay

A long length of stay is defined as a hospital stay after birth that exceeded 5 days. Note that only infants who were discharged home are included in the reference at risk population.
