Even though survival of premature infants has improved one in four extremely premature infants, those of the gestational age of twenty-two to twenty-eights weeks, did not survive the birth hospitalization (Patel et al., 2015, p. 332). Doctor Ravi M. Patel M.D., Sarah Kendefer M.D., Michele C. Walch M.D., and other researchers at the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network set out to find the “Causes and Timing of Death in Extremely Premature Infants from 2000 through 2011”. The study was performed to “…evaluate the causes and timing of death among extremely premature infants…” (Patel et al., 2015, p. 332). The researchers hypothesized that the frequency of pulmonary causes…show more content…
When an autopsy was available it was used as the primary cause of death. If a cause of death was not certain then a cause was reached by consulting the principle investigators. Also, deaths that could not be classified were labeled as other and causes that were not established were classified as unknown (Patel et al., 2015, p. 333). The study was broken into three birth year periods those being 2000-2003, 2004-2007, and 2008-2011. This was done to provide a sufficiently large sample to control for analysis and provide mortality estimates with greater precision (Patel et al., 2015, p. 333). From January 1, 2000, to December 31, 2011, a total of 22,248 extremely premature infants were born alive (Patel et al., 2015, p. 333). Among those infants, 6,075 died during their birth hospitalization (Patel et al., 2015, p. 333). Extremely premature infants who died were 2 weeks younger ( at 24.3 weeks) in gestational age than surviving infants (at 26.3 weeks) (Patel et al., 2015, p. 333). In addition, the study found that the administration of prenatal glucocorticoids was lower among mothers whose infants died than among those whose infants survived (Patel et al., 2015, p. 333). The researchers found an increase in the percentage of women who received prenatal care, prenatal glucocorticoids, and who delivered by cesarean section, as well as a decrease in the percentage of women who received prenatal antibiotic treatment (Patel et al., 2015, p.
