In 2020, HomVEE updated this review to move 18 findings related to child injuries and ingestions that were mistakenly placed in the Child Health domain to the Reductions in Child Maltreatment domain where HomVEE typically categorizes such findings.
| Study participants | The study population included 27,320 women (13,660 women each in the treatment and comparison groups) who were recipients of Medicaid, delivered a baby during the 2011 calendar year in Michigan, and for whom the baby survived his or her first year after birth. The study sample was, on average, 25 years old. Slightly less than 27 percent of the women were married. About 57 percent of women in the research sample were white, 37 percent were black, 5 percent were a different race or ethnicity, and less than 1 percent were American Indian. Just more than one-quarter of women in the research sample were living at or below 33 percent of the federal poverty level, and about two-thirds were receiving Medicaid before their pregnancy. |
|---|---|
| Setting | The study took place across the state of Michigan. |
| Intervention services | MIHP provides prenatal and postnatal home visiting to pregnant women and infants living in Michigan who are Medicaid beneficiaries. Participation is voluntary, and includes health risk screenings, care coordination, referrals to other services, and interventions that are tailored to the needs of each person. These interventions may address healthy pregnancies, positive birth outcomes, infant safety, and infant health and development. |
| Comparison conditions | People in the comparison condition received Medicaid during the study period but did not participate in any MIHP services. |
| Subgroups examined |
This field lists subgroups examined in the manuscript (even if they were not replicated in other samples and not reported on the summary page for this model’s report). Subgroups are not listed for manuscripts reviewed before 2021. |
| Funding sources | The study was partly supported through a grant from the Michigan Department of Community Health. |
| Author affiliation | None of the study authors are developers of this model. The authors explicitly reported no conflict of interest. |
| Peer reviewed | Peer reviewed status is not listed for manuscripts reviewed before 2021. |
Clinicaltrials.gov Identifier: None found. Study registration was assessed by HomVEE beginning with the 2014 review.
