Birth and Death Related Indicators (Bureau of Biometrics and Health Statistics)
Information is extracted from birth, death and fetal death certificates. The following are definitions of these indicators:
  • Infant Mortality: number of deaths less than 1 year of age per 1,000 live births.
  • Neonatal Mortality: number of deaths less than 28 days old per 1,000 live births.
  • Postneonatal Mortality: number of deaths between 28 days old and under 1 year of age per 1,000 live births.
  • Spontaneous Fetal Deaths (20+ weeks gestation) - Spontaneous fetal death rate is the number of spontaneous fetal deaths (gestation 20 weeks or more) per 1,000 spontaneous fetal deaths (gestation 20 weeks or more) plus live births.
  • Low Birthweight Births - Low birthweight births are the number of infants born weighing less than 2500 grams.
  • Very Low Birthweight Births - Very low birthweight births are the number of infants born weighing less than 1500 grams.
  • Short Gestation - Prematurity rate is the percent of infants born before 37 weeks gestation.
  • Maternal Mortality Rate - The number of deaths to women from any causes related to or aggravated by pregnancy or its management that occurred while pregnant or within 42 days of termination of pregnancy (ICD-10 codes O00-95, O98-O99, and A34 (obstetrical tetanus)) per 100,000 live births.

    Note: The maternal mortality definition has been revised to be consistent with the definition used by the World Health Organization. The previous definition used by NYSDOH (ICD 10 codes: O00-O99) to report maternal mortality included deaths that occurred outside this time period (ICD 10 codes: O96 and O97).

  • Early Prenatal Care - Early prenatal care is the number of births to women who began prenatal care within the first three months of pregnancy (first trimester).
  • Late or No Prenatal Care - Late or no prenatal care is the number of births to women who began prenatal care within the last 3 months of pregnancy (3rd trimester) or not at all.

Note: In 2008, New York City Vital Records adopted the National Center for Health Statistics standard birth certificate. This certificate has been used for births occurring in New York State outside of New York City since 2004. According to the New York City Health Department publication, Summary of Vital Statistics 2008 1, the use of the new certificate has resulted in some data quality concerns. A combination of poor data quality and hospital staff adaptation to the new data entry system and worksheets affected data quality. There is a potential for variables such as prenatal care and race/ethnicity to be impacted by a larger than normal number of unknowns and miscoding. Caution should be used when comparing the 2008 data to previous years.

Neonatal Drug Related Hospitalizations (Statewide Planning and Research Cooperative System-SPARCS)
Data on hospitalizations are collected through the hospital inpatient discharge data system, SPARCS. Data are not available on events that did not result in a hospitalization, such as cases that were only treated in hospital emergency room. Each hospitalization receives an ICD-9 code at discharge which indicates the primary reasons for the hospitalization. The ICD-9 codes included in the neonatal drug-related hospitalizations category were: 292, 304, 305.1-305.9,648.3, 655.5, 763.5, 779.4, 779.5, 965.0, 967.0, 968.5, 969.6, 969.7, 760.70, 760.72, 760.73, 760.75, 760.79, E850-E858, E950.0-E950.2, E962.0, E980.0-E980.2. Rates were calculated per 10,000 births.
