Brief Summary

Women with a history of a prior preterm birth (PTB) have a high probability of a recurrent preterm birth. Some risk factors and health behaviors that contribute to PTB may be amenable to intervention. Home visitation is a promising method to deliver evidence based interventions. We evaluated a system of care designed to reduce preterm births and hospital length of stay in a sample of pregnant women with a history of a PTB. All participants (N = 211) received standard prenatal care. Intervention participants (N = 109) also received home visits by certified nurse-midwives guided by protocols for specific risk factors (e.g., depressive symptoms, abuse, smoking). Data was collected via multiple methods and sources including intervention fidelity assessments. Average age was 27.6 years. Racial breakdown mirrored local demographics. Most women had a partner, a high school education, and Medicaid. Enhanced prenatal care by nurse-midwife home visits may limit some risk factors and shorten intrapartum length of stay for women with a prior PTB. This study contributes to knowledge about evidence-based home visit interventions directed at risk factors associated with PTB.

Outcome Measures

Primary Outcomes (1)

  • Infant Gestational Age

    Infant gestational age was determined by the weeks and days gestation documented in the maternal delivery record.

    Time of delivery

Secondary Outcomes (1)

  • Maternal Length of Stay at Delivery

    Hospital discharge point following delivery

Study Arms (2)

Targeted Nurse Home Visits

EXPERIMENTAL

Advanced practice nurses provide targeted behavioral interventions during home visits. These visits were in addition to regularly scheduled conventional prenatal and postpartum clinic visits. Specific protocols guided nurse interventions related to tobacco use, substance use and misuse, stress management, dental health, maternal infections, perinatal depressive symptoms, family violence, reproductive life plans and continuity of care. Home visits were continued in the postpartum period (through 18 months post-delivery) with a continued focus on risk factors identified during the prenatal period and internatal health care.
