Home visiting programmes show strong potential to cut long-term costs of child maltreatment

A comprehensive study of over 4,200 families demonstrates that early, community-based home visitation can significantly reduce child maltreatment, improve maternal and family well-being, and save billions in future system costs, posing a compelling case for scaling prevention efforts.

A long-running home visiting trial is being used to make a blunt case for prevention: if a trained visitor keeps turning up at the door of a struggling family, child maltreatment and later system costs can fall sharply. The argument is not built on theory but on a randomised study of 4,229 families enrolled when a mother was pregnant or had a baby under six months old. Five years later, the follow-up reported better maternal mental and behavioural health, stronger parent-child interactions, improved family finances and a reduction in conflict, violence, aggression and maltreatment, according to MDRC’s report on the Mother and Infant Home Visiting Program Evaluation.

That matters because the burden of adverse childhood experiences is enormous. A 2023 study in JAMA Network Open estimated that 63% of US adults have at least one ACE, with an annual economic burden of $14.1tn. Of that, $183bn was direct medical spending and $13.9tn represented lost healthy life-years. The study put the annual burden at about $88,000 per affected adult and $2.4m over a lifetime, underscoring how early harm echoes across health, work and family life.

The home visiting evidence is also more specific than advocates sometimes allow. MIHOPE examined four national models: Early Head Start-Home Visiting Option, Healthy Families America, Nurse-Family Partnership and Parents as Teachers. The revised design and later analysis plan show that the evaluation was built to measure effects not just on child development, but on maternal health, parenting and family self-sufficiency. In other words, the programme was tested as a practical intervention for at-risk households, not as a feel-good add-on.

The central insight is that the visitor does not always need to be a nurse. The evaluation included nurse-led and non-clinical models, which strengthens the broader case for using trained community visitors where that is what families will accept. That distinction matters in child protection, where trust is fragile and access is often the first obstacle. A model that never gets through the front door cannot change what happens inside it.

The cost argument is equally stark. The supplied materials cite federal cost estimates for evidence-based home visiting that place a first year of service in the low thousands of dollars per family, with three years of support running to a fraction of the cost of a prison sentence, a foster placement or a prolonged court case. That is why prevention advocates frame home visiting as one of the few interventions that can move money upstream, before abuse, neglect and trauma harden into more expensive crises.

The wider system price is visible in Minnesota. Child Trends’ 2026 state factsheet says the state’s child welfare agencies spent $848.3m in fiscal 2024, with counties carrying the largest share, followed by federal and state dollars. The same summary says 29,881 children received a child protection investigation or alternative response and 9,992 spent time in foster care. Yet the article’s key point is that, within that child welfare spending, the amount routed through the federal home visiting programme and the Title IV-E Prevention Programme was zero.

That gap is especially striking because the evidence base is now broad enough to justify scale rather than pilots. The federal evaluation focused on long-term follow-up, including kindergarten-age outcomes, precisely because short-term gains are not the whole story. The report’s finding that family functioning and maltreatment outcomes improved gives policymakers a firmer basis for funding prevention alongside crisis response, rather than treating the two as separate worlds.

The article also widens the frame to juvenile justice and incarceration, arguing that the state often pays far more later than it would have paid for support earlier. Minnesota’s correctional costs, residential placements and guardian ad litem spending are presented as examples of the price of waiting until harm has already rippled outward. The underlying point is simple: if prevention can reduce violence, instability and maltreatment in the home, then it can also reduce the downstream costs that arrive years later in courtrooms, prisons and hospitals.

What emerges is less a plea for sympathy than a ledger. The evidence from home visiting, ACE research and state spending all points in the same direction: early support for high-risk families is not a marginal service, but a relatively modest investment against a very large public bill. The question for governments is whether they want to keep paying for the aftermath, or fund the visit that may prevent it in the first place.
