Effect of an Intensive Nurse Home Visiting Program on Adverse Birth Outcomes in a Medicaid-Eligible Population: A Randomized Clinical Trial

Mortality, morbidity, and childhood developmental challenges can all result from adverse birth outcomes. In regard to these outcomes, the United States exhibits significant racial and socioeconomic inequities, and effective interventions targeting low-income pregnant people are necessary. A recommendation for expanding home visiting programs has been provided with the hope of improving newborn and maternal outcomes, and substantial federal funding is granted to these programs via the Maternal, Infant, and Early Childhood Home Visiting program. The Nurse-Family Partnership program is a nurse home visiting service targeting nulliparous low-income families during pregnancy and early childhood. The state of South Carolina's preterm birth rate in 2016 was the sixth highest in the United States, which motivated the state to offer program services to Medicaid-eligible nulliparous women through a Medicaid waiver. This study's objective was to determine effects of intensive nurse home visiting programs on the composite outcome of small for gestational age, low birth weight, preterm birth, and perinatal mortality. This randomized clinical trial assigned participants in a 2:1 ratio to either a control group or an intervention group, which was offered access to the program. The control group was offered a list of community-based resources available to them, and all participants received usual care for South Carolina. Inclusion criteria were nulliparous pregnancy of less than 28 weeks' gestation, income-eligible for Medicaid during pregnancy, and residence in a program-served county. Self-referral, or referral through schools, clinicians, and Medicaid led patients to 1 of 9 program-implementing sites. The intervention, which consisted of a prenatal and early childhood home visiting program, was carried out by nurses conducting home visits with participants from pregnancy through the first 2 years of the child's life. The nurses used activities tailored to the clients' strengths, preferences, and risks via educational tools, motivational interviews, goal setting related to prenatal health, health assessments, maternal life course, and child health and development. Utilization of health care was encouraged when needed, coupled with referrals to health and social services. Ideal visits ranged from weekly 60-to 90-minute sessions for 4 weeks following enrollment and then every other week leading up to delivery. Nurse training encouraged flexible support of clients for more or fewer visits as necessary, with services provided in both Spanish and English, with other translation options. Enrollment for the study began on April 1, 2016, but concerns for the COVID-19 pandemic led to a recruitment halt on March 17, 2020. However, 95% of the target recruitment goal had already occurred, and the remaining home visits were conducted via telehealth. A total of 3319 patients were eligible and opted for enrollment. Upon time of enrollment, 18% of participants were younger than 19 years, with 54.8% of them between 19 and 24 years old. Self-reported race and ethnicity statistics were reported as 55.2% non-Hispanic Black, and 22.4% had not completed high school. Body mass index of greater than 30 kg/m2 was present in 34.5%, and smoking 3 months before pregnancy was reported in 25.8% of participants.

Automated summary

Adverse birth outcomes can lead to mortality, morbidity, and childhood developmental challenges. The United States has significant racial and socioeconomic disparities in these outcomes, requiring effective interventions for low-income pregnant individuals. Expanding home visiting programs, specifically the Nurse-Family Partnership program, is recommended to improve newborn and maternal outcomes. This study aims to determine the effects of intensive nurse home visiting programs on crucial birth outcome indicators.
