USPSTF: Insufficient Evidence for Primary Care Interventions to Prevent Child Maltreatment

While primary care physicians are uniquely positioned to identify mistreated minors, there is insufficient evidence of benefits and harms to support primary care interventions to prevent maltreatment in children who have no indicative signs or symptoms. That is the conclusion of the US Preventive Services Task Force (USPSTF) in an update of its 2018 statement published in JAMA Network Open.

This gap, however, might be partially filled by addressing in young patients the known social determinants of health such as economic stability, food, shelter, and healthcare access. The USPSTF statement is based on a simultaneously published evidence review and synthesis compiled by Meera Viswanathan, PhD, of the RTI International-University of North Carolina at Chapel Hill Evidence-Based Practice Center in Triangle Park, NC, and colleagues.

The review included 14,355 participants in 25 trials, of which 23 included home visits. It measured such things as direct reports to Child Protective Services or removal of children from the home and proxy measures of abuse or neglect such as injury, emergency department visits, and hospitalizations. In addition, it looked at behavioral, developmental, emotional, mental or physical health and well-being, mortality, and harms.

More than 50% of the studies analyzed consisted of children with no prior reports of maltreatment. In addition to limited and inconsistent findings, the researchers noted wide variance in screening, identifying, and reporting child maltreatment to authorities, including variations by race or ethnicity, as well as wide variance in the accuracy of screening instruments.

“Contextual evidence pointed to the potential for bias or inaccuracy in screening, identification, and reporting of child maltreatment but also highlighted the importance of addressing social determinants when intervening to prevent child maltreatment,” Dr. Viswanathan’s group wrote.

The USPSTF panel, chaired by Michael J. Barry, MD, of Harvard Medical School, Boston, Massachusetts (now immediate past chair of the Task Force), stressed that the current statement applies only to children with no signs of maltreatment: Those with direct signs should be assessed and appropriately reported.

A Common and Costly Problem

Child abuse or neglect is widespread and has long-lasting adverse effects. In 2021, the statement noted, Child Protective Services identified 600,000 children as abused or neglected, with 1821 related deaths. Most (76%) experienced neglect, but many were subjected to physical abuse (16%), sexual abuse (10%), and sex trafficking (0.2%). Of the 1820 who died, 78% experienced neglect and 43% experienced physical abuse alone or combined with maltreatment such as neglect and psychological abuse.

Benefits aside, among the potential harms of intervention, the USPSTF noted, is family stigma and bias toward non-White and low-income groups. There may be a greater probability of clinicians’ disproportionately reporting abuse for the children of Black, Hispanic, indigenous, and one-parent households. Some studies indicate that more cases of maltreatment are missed in White children, the review authors noted.

“Additional evidence is needed to clarify potential linkages between improvements in social determinants of health and child maltreatment prevention,” the USPSTF panelists concluded. They acknowledged that their recommendation does not address the effectiveness of interventions such as home visits to improve family well-being.

In an accompanying editorial Samantha Schilling, MD, MSHP, of the Department of Pediatrics at the University of North Carolina at Chapel Hill, and colleagues from the Children’s Hospital of Philadelphia in Pennsylvania admitted they were “disheartened, but not surprised” at the USPSTF’s conclusions and urged that prevention measures be continued. “It is not yet time to wave the white flag of surrender and abandon primary care–based efforts to mitigate risks for child abuse and neglect.

They sent a heartfelt message to primary care doctors: “Know this: while additional evidence is amassed, do not stop your ongoing efforts to protect vulnerable children. You are an important component of child maltreatment prevention, although your actions and support cannot be delivered (or measured) in isolation.”

Dr. Schilling and associates argued that insufficient evidence does not mean that primary care prevention efforts are ineffective, only that evidence is lacking. They pointed out that proximal outcomes along a causal pathway have been used to assess the effectiveness of preventive measures and should be considered in this context. “For example, based on evidence that counseling about minimizing exposure to UV radiation is associated with a moderate increase in use of sunscreen protection, the USPSTF recommends that counseling be provided to certain populations,” they wrote. “The USPSTF did not require direct evidence that counseling decreases skin cancer.”

More high-quality research is needed, as the USPSTF recognized. “Given the inadequacy of the current gold standard measures of child maltreatment, proximal outcomes on the complex, multifactorial, causal pathway to child abuse and neglect should be considered,” the commentators wrote.

The commentators also acknowledged that patients’ caregivers often struggle to do their best with sparse resources and that resources such as food and housing, treatment for substance use and mental health disorders, appropriate strategies to manage typical child behavior, and affordable child care too often fall short.

They argued, therefore, that consequential prevention is not possible without sustained investment in policies and programs that provide tangible support to families, reduce childhood poverty, and target relevant risk factors.

The Agency for Healthcare Research and Quality of the US Department of Health and Human Services supports the operations of the USPSTF. Dr. Barry reported grants from Healthwise, a nonprofit organization, outside of the submitted work. Dr. Silverstein reported receiving a research grant on approaches to child maltreatment prevention. Dr. Lee reported grants from the National Institute on Aging. The evidence review was supported by a grant from the Agency for Healthcare Research. Dr. Viswanathan and colleagues disclosed no conflicts of interest. Dr. Wood reported grants from the Annie E. Casey Foundation outside of the submitted work. Dr. Christian reported personal fees from multiple government agencies and legal firms and provides medical-legal expert work in child abuse cases outside of the submitted work.
