Perinatal and Medicaid Data Methodology


The MMD Perinatal Care Project collected Medicaid delivery data from 22 states, representing over 830,000 singleton births. All Medicaid singleton births in a given calendar-year (for most states, 2011) as well as trend data were reported by individual states. 

The 22 states which reported aggregated data for this study include:

Data Collection Tools


Methods using birth certificates, by themselves or linked to Medicaid administrative data, were found to be appropriate for examining the problem of elective deliveries across the Medicaid population and when looking at other comparators (i.e. gestational ages, all planned births). The collection of this measure can be linked to mechanisms for rapid feedback to states and providers, making it an appropriate measure for use quality improvement purposes in the Medicaid populations. 


For the purposes of the project, an elective delivery was defined as any labor induction or cesarean delivery without justification of a maternal or fetal medical condition, as indicated on the 1989 or 2003 version of the birth certificate. This calculated rate of elective deliveries is based on the measure used in the Health Resources and Services Administration Collaborative Improvement & Innovation Network (CoIN).

Test
This is a retrospective cohort study designed to analyze neonatal mortality and morbidity rates at 34, 35, and 36 weeks of gestation compared with births at term over the past 18 years at the authors' hospital and to estimate the magnitude of increased risk associated with late preterm births compared with births later in gestation.
Test
In this study, researchers linked compulsory national registries in Norway to identify children of different gestational-age categories who were born between 1967 and 1983 and to follow them through 2003 in order to document medical disabilities and outcomes reflecting social performance.
Test
Researchers sought to evaluate number and timing of elective cesarean sections at term and to assess perinatal outcome associated with this timing by conducting a retrospective cohort study including all elective cesarean sections of singleton pregnancies at term (n = 20,973) with neonatal follow-up. Primary outcome was defined as a composite of neonatal mortality and morbidity.
