Summary
Advanced-practice nurse-obstetrician collaborative prenatal care significantly reduced low birth weight and preterm delivery rates in medically low-risk patients. This collaborative model demonstrates effective implementation and positive perinatal outcomes.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Nursing Practice
Background:
- Collaborative practice models integrating advanced-practice nurses and obstetricians are emerging in prenatal care.
- Evaluating the effectiveness of such models is crucial for optimizing perinatal outcomes.
- Existing models often focus on high-risk pregnancies, necessitating research into low-risk populations.
Purpose of the Study:
- To assess the efficacy of an advanced-practice nurse-obstetrician collaborative prenatal practice.
- To compare perinatal outcomes, specifically low birth weight, between collaborative care and traditional obstetric clinics.
- To identify demographic and clinical factors influencing outcomes in collaborative care settings.
Main Methods:
- A comparative study involving 194 medically low-risk obstetric patients in a collaborative practice and an equal number in a university clinic.
- Data collected from January 1, 1994, to December 31, 1994.
- Primary outcome: low birth weight. Secondary outcomes: preterm delivery. Statistical analyses included chi-squared, Fisher exact test, t-test, and regression models.
Main Results:
- Collaborative care patients were more often teenagers and Black, less likely to be married or employed, and had more prenatal visits.
- Significantly lower rates of delivery before 37 weeks (7.3% vs. 17.7%) and low birth weight (<2500g) (8.9% vs. 19.3%) were observed in the collaborative group.
- Multivariate analysis confirmed that collaborative practice was independently associated with reduced odds of low birth weight (OR 0.46) and preterm delivery (OR 0.36).
Conclusions:
- Advanced-practice nurse-obstetrician collaborative prenatal practice can be successfully implemented.
- This model leads to acceptable perinatal outcomes, evidenced by reduced rates of low birth weight and prematurity.
- Collaborative care models show promise for improving maternal and infant health outcomes in low-risk obstetric populations.
