Maternal and hospital characteristics of non-medically indicated deliveries prior to 39 weeks.

Non-medically indicated (NMI) deliveries prior to 39 weeks increase the risk of neonatal mortality, excess morbidity, and health care costs. The study's purpose was to identify maternal and hospital characteristics associated with NMI deliveries prior to 39 weeks. The study included 207,775 births to women without a previous cesarean and 38,316 births to women with a previous cesarean, using data from Florida's 2006-2007 linked birth certificate and inpatient record file.

Unreliable medical information on birth certificates.

Objective: To compare selected maternal, obstetric and newborn medical information on live birth certificates to medical record abstracted data.

Study Design: The Florida Department of Health provided a computer tape containing the Hillsborough County Florida live birth certificate data for July 1, 1992, through December 31, 1996. This information was compared to selected maternal, obstetric and newborn medical data abstracted from the hospital records of women who delivered in that county.
