There is a popular perception that insurance coverage will reduce overuse of the emergency department (ED). Both opponents and advocates of expanding insurance coverage under the Affordable Care Act (ACA) have made statements to the effect that EDs have been jammed with the uninsured and that paying for the uninsured population’s emergency care has burdened the health care system as a result of the expense of that care. It has therefore been surprising to many to encounter evidence that insurance coverage increases ED use instead of decreasing it. Two facts may help explain this unexpected finding. First, there is a common misperception that the uninsured use the ED more than the insured. In fact, insured and uninsured adults use the ED at very similar rates and in very similar circumstances—and the uninsured use the ED substantially less than the Medicaid population. Second, while the uninsured do not use the ED more than the insured, they do use other types of care much less than the insured.

ImportanceImproving 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.ObjectiveTo 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 ParticipantsThis 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.InterventionsParticipants 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 MeasuresThere 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.ResultsAmong 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 RelevanceIn 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.Trial RegistrationClinicalTrials.gov Identifier: NCT03360539

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).

Objective: To characterize physician health system membership in four states between 2012 and 2016 and to compare primary care quality and cost between insystem providers and non-system providers for the commercially insured population. Data Sources: Physician membership in health systems was obtained from a unique longitudinal database on health systems and matched at the provider level to 2014 all-payer claims data from Colorado, Massachusetts, Oregon, and Utah. Study Design: Using an observational study design, we compared physicians in health systems to non-system physicians located in the same state and geography on average cost of care (risk-adjusted using the Johns Hopkins' Adjusted Clinical Grouper), five HEDIS quality measures, one measure of developmental screening, and two Prevention Quality Indicator Measures. Data Collection/Extraction Methods: Patients in commercial health plans were attributed to a primary care physician accounting for the plurality of office visits. A cohort for each quality measure was constructed based on appropriate measure specifications.

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 lowincome 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-repor...
