Home Visits With A Registered Nurse Did Not Affect Prenatal Care In A Low-Income Pregnant Population.

There is an urgent need to improve maternal and neonatal health outcomes and decrease their racial disparities in the US. Prenatal nurse home visiting programs could help achieve this by increasing the use and quality of prenatal care and facilitating healthy behaviors during pregnancy. We conducted a randomized controlled trial of 5,670 Medicaid-eligible pregnant people in South Carolina to evaluate how a nurse home visiting program affected prenatal health care and health outcomes. We compared outcomes between the treatment and control groups and found little evidence of statistically significant differences in the intensity of prenatal care use, receipt of guideline-based prenatal care services, other health care use, or gestational weight gain. Nor did we find treatment effects in subgroup analyses of socially vulnerable participants (46.9 percent of the sample) or non-Hispanic Black participants (52.0 percent of the sample). Compared with the broader Medicaid population, our trial participants had more health and social risk factors, more engagement with prenatal care, and similar pregnancy outcomes. Delivering intensive nurse home visiting programs to the general Medicaid population might not be an efficient method to improve prenatal care for those who need the most support during pregnancy.

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

Importance: Improving birth outcomes for low-income mothers is a public health priority. Intensive nurse home visiting has been proposed as an intervention to improve these outcomes. Objective: To determine the effect of an intensive nurse home visiting program on a composite outcome of preterm birth, low birth weight, small for gestational age, or perinatal mortality. Design, Setting, and Participants: This was a randomized clinical trial that included 5670 Medicaid-eligible, nulliparous pregnant individuals at less than 28 weeks' gestation, enrolled between April 1, 2016, and March 17, 2020, with follow-up through February 2021. Interventions: Participants were randomized 2:1 to Nurse Family Partnership program (n = 3806) or control (n = 1864). The program is an established model of nurse home visiting; regular visits begin prenatally and continue through 2 postnatal years. Nurses provide education, assessments, and goal-setting related to prenatal health, child health and development, and maternal life course. The control group received usual care services and a list of community resources. Neither staff nor participants were blinded to intervention group. Main Outcomes and Measures: There were 3 primary outcomes. This article reports on a composite of adverse birth outcomes: preterm birth, low birth weight, small for gestational age, or perinatal mortality based on vital records, Medicaid claims, and hospital discharge records through February 2021. The other primary outcomes of interbirth intervals of less than 21 months and major injury or concern for abuse or neglect in the child's first 24 months have not yet completed measurement. There were 54 secondary outcomes; those related to maternal and newborn health that have completed measurement included all elements of the composite plus birth weight, gestational length, large for gestational age, extremely preterm, very low birth weight, overnight neonatal intensive care unit admission, severe maternal morbidity, and cesarean delivery. Results: Among 5670 participants enrolled, 4966 (3319 intervention; 1647 control) were analyzed for the primary maternal and neonatal health outcome (median age, 21 years [1.2% non-Hispanic Asian, Indigenous, or Native Hawaiian and Pacific Islander; 5.7% Hispanic; 55.2% non-Hispanic Black; 34.8% non-Hispanic White; and 3.0% more than 1 race reported [non-Hispanic]). The incidence of the composite adverse birth outcome was 26.9% in the intervention group and 26.1% in the control group (adjusted between-group difference, 0.5% [95% CI, -2.1% to 3.1%]). Outcomes for the intervention group were not significantly better for any of the maternal and newborn health primary or secondary outcomes in the overall sample or in either of the prespecified subgroups. Conclusions and Relevance: In this South Carolina-based trial of Medicaid-eligible pregnant individuals, assignment to participate in an intensive nurse home visiting program did not significantly reduce the incidence of a composite of adverse birth outcomes. Evaluation of the overall effectiveness of this program is incomplete, pending assessment of early childhood and birth spacing outcomes.

Protocol for a randomized controlled trial evaluating the impact of the Nurse-Family Partnership's home visiting program in South Carolina on maternal and child health outcomes.

BACKGROUND: Policy-makers are increasingly seeking rigorous evidence on the impact of programs that go beyond typical health care settings to improve outcomes for low-income families during the critical period around the transition to parenthood and through early childhood. METHODS: This study is a randomized controlled trial evaluating the impact of the Nurse-Family Partnership's expansion in South Carolina. The scientific trial was made possible by a "Pay for Success" program embedded within a 1915(b) Waiver from Medicaid secured by the South Carolina Department of Health and Human Services. This protocol describes study procedures and defines primary and secondary health-related outcomes that can be observed during the intervention period (including pregnancy through the child's first 2 years of life). Primary study outcomes include (1) a composite indicator for adverse birth outcomes including being born small for gestational age, low birth weight (less than 2500 g), preterm birth (less than 37 weeks' gestation), or perinatal mortality (fetal death at or after 20 weeks of gestation or mortality in the first 7 days of life), (2) a composite outcome indicating health care utilization or mortality associated with major injury or concern for abuse or neglect occurring during the child's first 24 months of life, and (3) an indicator for an inter-birth interval of < 21 months. Secondary outcomes are defined similarly in three domains: (1) improving pregnancy and birth outcomes, (2) improving child health and development, and (3) altering the maternal life course through changes in family planning. DISCUSSION: Evidence from this trial on the impact of home visiting services delivered at scale as part of a Medicaid benefit can provide policy-makers and stakeholders with crucial information about the effectiveness of home visiting programs in improving health and well-being for low-income mothers and children and about novel financing mechanisms for cross-silo interventions. TRIAL REGISTRATION: The trial was registered prospectively on the American Economic Association Trial Registry (the primary registry for academic economists doing policy trials) on 16 February 2016 ( AEARCTR-0001039 ). ClinicalTrials.gov NCT03360539 . Registered on 28 November 2017.
