Expanded PRAMS data now available

In collaboration with the Centers for Disease Control and Prevention’s (CDC) Division of Reproductive Health, the March of Dimes has expanded the number of Pregnancy Risk Assessment Monitoring System (PRAMS) indicators available on PeriStats.

The 13 new indicators largely encompass preconception and interconception care and include data on pregnancy intention and contraception use at time of conception, pre-pregnancy morbidities like diabetes and hypertension, and postpartum contraception use, checkups, and depressive symptoms, among others.

Data for the new indicators are available for 2000-2011, depending on the state, and are available stratified by maternal race/ethnicity and age, household income, and Medicaid status.

PRAMS is a system of state and population based surveys that routinely collect information about maternal behaviors and experiences before, during, and shortly after pregnancy. Participating PRAMS states survey a sample of women who have had a recent live birth and link survey responses to medical information collected on birth certificates to produce statewide estimates of maternal health indicators.

MMWR article about Tdap vaccine coverage

May 26, 2015 A recent article published by the Centers for Disease Control and Prevention (CDC) describes Tdap vaccine coverage among women who were recently pregnant. The authors of the article, published in the May 22nd edition of Morbidity and Mortality Weekly, analyzed data from the Pregnancy Risk Assessment Monitoring System (PRAMS) data in 16 states and New York City (NYC).

The Tdap vaccine provides protection from three diseases: tetanus, diphtheria and pertussis. The protection offered by this vaccine against pertussis is particularly important for newborns, who are most vulnerable to the highly contagious disease. The number of cases of pertussis has been increasing since the 1980s. In 2012, more than 48,000 cases were reported. When a woman is vaccinated with the Tdap vaccine during pregnancy (in the 3rd trimester) she passes on her immunity to her baby before birth.

The CDC study estimates that in 2011, 55.7% of women in the US received the Tdap vaccine before, during, or after their most recent pregnancy. This percentage varied widely across states from 38.2% in NYC to 76.6% in Nebraska. Women who started prenatal care earlier were more likely to report they received the vaccine. Among women who reported being vaccinated most reported receiving the vaccine after delivery.

The article is available on the CDC website or by clicking here.

PeriStats has data by maternal race/ethnicity and maternal age for 17 pregnancy related topics from PRAMS. For additional PRAMS data and Tdap coverage in your state go to the CDC PRAMStat website.

Birth Defects Data Now Available on PeriStats

December 2014

PeriStats has recently been expanded to include state-level data on birth defects from the National Birth Defects Prevention Network (NBDPN).

NBDPN, in collaboration with the Centers for Disease Control and Prevention, collects and reports data on major birth defects from state birth defects surveillance systems. Birth defects are generally referred to as abnormalities of structure, function or metabolism (body chemistry) present at birth that result in physical or mental disabilities, or death.

Through a cooperative agreement with the CDC, NBDPN birth defects data for 2007-2011 from 37 states for 47 conditions are now available on PeriStats. Most prevalence rates are reported as a prevalence per 10,000 live births and are provided by maternal race/ethnicity. In addition, chromosomal defects are also provided stratified by maternal age, a known risk factor for these defects.

For more information and to view the current Annual Congenital Malformations Surveillance Project Report, visit the NBDPN website.

Aug 19, 2013- PeriStats has been updated with the latest data from the National Center for Health Statistics for fetal and perinatal mortality in the United States for 2006.

Fetal mortality is the death of a fetus prior to delivery. Perinatal mortality is a measure of death around the time of delivery and includes fetal deaths of at least 28 weeks of gestation and infant deaths at less than 7 days old. PeriStats displays information about the US, states, counties, and cities and by maternal age, race, and Hispanic ethnicity.


Special Care Nursery Admissions

WHITE PLAINS, N.Y., Oct. 19, 2011- The March of Dimes Perinatal Data Center has partnered with the National Perinatal Information Center/Quality Analytic Services (NPIC/QAS) to describe special care nursery admissions among NPIC/QAS member hospitals.

Specialty care was defined as any time spent by the infant in a neonatal intermediate care unit (NINT, Level II nursery) or a neonatal intensive care unit (NICU, Level III nursery) bed at any time during the hospital stay. Key findings from the analyses included:

  • 14.4% of newborns delivered at or transferred to NPIC/QAS member hospitals were admitted to a special care nursery.
  • Among all special care nursery admissions, 49.1% were preterm, 50.4% were term (37-41 weeks) and less than 1% were post-term.
  • The average length of the hospital stay for newborns admitted to a special care nursery was 13.2 days, with an average hospital charge of $76,000.
