Do Obstetrical Quality Measures Explain Racial Disparities in Perinatal Outcomes

DESCRIPTION (provided by applicant): Persistent Black/White disparities in neonatal and maternal mortality rates are a major public health concern and the United States continues to rank poorly on these measures when compared to other nations. Despite billions of dollars spent in health care annually and nearly half of all births occurring to minority women, performance and quality measures in obstetrical care have yet to be thoroughly examined. Although hospital quality has been associated with neonatal very low birth weight (VLBW) mortality and obstetrical outcomes, little research has addressed the role of current obstetrical quality measures in explaining racial/ethnic disparities in neonatal mortality and other maternal health outcomes, specifically maternal mortality. We propose a study to investigate variability of 35 recommended obstetrical quality measures across hospitals and to conduct analyses using these measures to investigate racial/ethnic disparities in neonatal and maternal mortality rates. Our objectives are to: 1) Pilot the use of current obstetrical quality indicators in routine data sources to measure variability across hospitals; 2) determine whether obstetrical quality measures differ by race/ethnicity and 3) examine whether racial/ethnic differences explain variation in racial/ethnic disparities in maternal and neonatal mortality rates. Methods: We will use the National Inpatient Sample (NIS), New York State Discharge Abstract Data (SPARCS), and the Mount Sinai Warehouse (electronic medical records) to investigate variation in obstetrical quality indicators among designated hospitals. We will also use Census Bureau data for community socio-economic status variables and AMA data for hospital characteristics. We will use the specific data elements required for measurement of these quality indicators as defined by the Joint Commission and other national quality leaders. The relationship between quality indicators and socio-economic status and clinical risk factors will also be assessed in order to identify those indicators most susceptible to bias. Lastly, we will conduct analyses to examine whether obstetrical quality differs by race/ethnicity, and whether such differences explain racial/ethnic disparities in maternal and VLBW neonatal mortality rates. Information from this study will provide a better understanding of quality in neonatal and maternity care in hospitals and reveal specific processes of care that could be improved upon to reduce racial/ethnic disparities in obstetrical-related outcomes in the future.
