Abstract

Background: Numerous study results vary when analyzing the relationship between labor induction and the likelihood of cesarean delivery; and few have accounted for the multiple influences of maternal sociodemographic characteristics combined with the provider and hospital in subsequent birth outcomes such as cesarean section.

Objective: This study evaluated the likelihood of cesarean birth following labor induction while accounting for maternal, hospital, and provider  characteristics.

Methods: A cross-sectional retrospective descriptive design using secondary data was employed to determine what variation in cesarean births was due to differences of hospitals, providers, and patients using the Quality Health Outcomes Model (QHOM). Data were partitioned by primiparous and multiparous women. The individual demographic, system, and provider outcomes in all hospitals and single birth center for Maricopa County in 2005 (N=62,816) were analyzed, using both random effects and fixed effects models.

Results: For primiparous women, an increased likelihood of cesarean births was associated with medical inductions, maternal age, being Black, and the number of prenatal visits; and less likely in teaching hospitals and women with higher educational attainment. In multiparous women, cesarean births were associated with increased maternal age and medical inductions; and less likely in for-profit hospitals and following elective induction.

Discussion: Labor inductions were associated with an increased likelihood of cesarean sections based on parity, age, race, number of prenatal visits, education, and hospital teaching status and ownership. Because the QHOM emphasizes multiple contextual variables that influence the delivery and outcomes of care, it can prove ideal for the study of birth outcomes following interventions such as the induction of labor.

Clinical Relevance: Nurses should be well educated about the risks of elective labor induction prior to term gestation and “elective” cesarean birth.
