“…No similar increase was observed in the other two early GA categories (23-25 or 26-28 weeks); rather, there was a slight but statistically significant decrease in these other categories. These findings are consistent with two previous investigations in the state of Alabama Phelan et al, 1998 It is also unlikely that the increase in FDs at 20-22 weeks can be attributed to increased termination of pregnancies (due to early diagnosis of lethal congenital anomalies such as anencephaly, spina bifida). The latter was suggested to be responsible for the increase in congenital anomaly-related FDs at 20-25 weeks from 1985 to 1996 in Canada (using Statistics Canada's birth and death databases) (Liu et al, 2001 (David RJ, 1986;).…”

US Birth Weight/Gestational Age-Specific Neonatal Mortality: 1995–1997 Rates for Whites, Hispanics, and Blacks

et al. 2003

ABSTRACT. Objective. In recent years, gains in neonatal survival have been most evident among very low birth weight, preterm, and low birth weight (LBW) infants. Most of the improvement in neonatal survival since the early 1980s seems to be the consequence of decreasing birth weight-specific mortality rates, which occurred during a period of increasing preterm and LBW rates. Although the decline in neonatal mortality has been widely publicized in the United States, research suggests that clinicians may still underestimate the chances of survival of an infant who is born too early or too small and may overestimate the eventuality of serious disability. So that clinicians may have current and needed ethnic-and race-specific estimates of the "chances" of early survival for newborn infants, we examined birth weight/gestational age-specific neonatal mortality rates for the 3 largest ethnic/racial groups in the United States: non-Hispanic whites, Hispanics, and non-Hispanic blacks. Marked racial variation in birth weight and gestational age-specific mortality has long been recognized, and growing concerns have been raised about ongoing and increasing racial disparities in pregnancy outcomes. Our purpose for this investigation was to provide an up-to-date national reference for birth weight/ gestational age-specific neonatal mortality rates for use by clinicians in care decision making and discussions with parents.Methods. The National Center for Health Statistics linked live birth-infant death cohort files for 1995-1997 were used for this study. Singleton live births to US resident mothers with a reported maternal ethnicity/race of non-Hispanic white, non-Hispanic black, or Hispanic (n ‫؍‬ 10 610 715) were selected for analysis. Birth weight/ gestational age-specific neonatal mortality rates were calculated using 250 g/2-week intervals for each ethnic/racial group.Results. The overall neonatal mortality rates for whites, Hispanics, and blacks were 3.24, 3.45, and 8.16 neonatal deaths per 1000 live births, and the proportion of births <28 weeks was 0.35%, 0.45%, and 1.39%, respectively. Newborns who weighed <1500 g comprised <2.5% of all births in each racial/ethnic group but accounted for >50% of neonatal deaths. For whites, Hispanics, and blacks, >50% of newborns 24 to 25 weeks of gestational age survived. For most combinations of birth weights <3500 g and gestational ages of <37 weeks, the neonatal mortality rate was lowest among blacks, compared with whites or Hispanics. At these same gestational age/birth weight combinations, Hispanics have slightly lower mortality rates than whites. For combinations of birth weights >3500 g and gestational ages of 37 to 41 weeks, Hispanics had the lowest neonatal mortality rate. In these birth weight/gestational age combinations, where approximately two thirds of births occur, blacks had the highest neonatal mortality rate.Conclusions. Compared with earlier reports, these data suggest that a substantial improvement in birth weight/gestational age-specific neonatal mortality has o...

“…Incomplete reporting of live births less than 500 grams (g) and changes in state reporting rules for fetal deaths, resulting in more fetal deaths or fetal deaths being recorded as live births, may mask improvements in neonatal mortality despite clear reductions in birth-weight-specific mortality [4]. Timeliness of data availability affects the speed with which programs can detect changes in IMR and respond.…”

States can improve pregnancy outcomes by using a standard approach to assess infant mortality. The State Infant Mortality Collaborative (SIMC) developed a series of analyses to describe infant mortality in states, identify contributing factors to infant death, and develop the evidence base for implementing new or modifying existing programs and policies addressing infant mortality. The SIMC was conducted between 2004 and 2006 among five states: Delaware, Hawaii, Louisiana, Missouri, and North Carolina. States used analytic strategies in an iterative process to investigate contributors to infant mortality. Analyses were conducted within three domains: data reporting (quality, reporting, definitional criteria, and timeliness), cause and timing of infant death (classification of cause and fetal, neonatal, and postneonatal timing), and maturity and weight at birth/maturity and birth weight-specific mortality. All states identified the SIMC analyses as useful for examining infant mortality trends. In each of the three domains, SIMC results were used © Springer Science+Business Media New York 2012 Correspondence to: Caroline Stampfel, cstampfel@amchp.org.

All partners contributed to the initial design, eligibility criteria, five-state selection process, and/or ongoing scientific and technical assistance. We examine the benefits of this standard approach for assessing infant mortality by: (1) describing the SIMC process, including a comparison of five state analyses on direct contributors to infant mortality; (2) defining the strategies identified for each analysis; and (3) summarizing application of analytic findings to modify existing policies or programs. HHS Public Access DescriptionBetween 2004 and 2006, the SIMC was implemented to aid states in investigation of infant mortality through facilitated meetings with subject matter experts, review and recommendation of appropriate data sources, development of standard approaches for analyses of infant mortality causes and contributors, and interpretation of findings both consistent with the literature and useful for each participating state for programmatic and policy-making decisions.Using available infant mortality data for all 50 states and the District of Columbia, eligibility for application to the collaborative was determined using information reflecting high or increasing burden of infant mortality. The following information was used to score state Author Manuscript Author ManuscriptAuthor Manuscript Author Manuscript eligibility: (1) three types of trend analyses, (2) the states' average IMR, and (3) states' raceadjusted IMR. Of 22 states which met the minimum scoring, the top 13 were determined to be eligible for the project; eight states applied and five were selected to participate, including Delaware, Hawaii, Louisiana, Missouri, and North Carolina. Each selected s...
