Identification during the postpartum period of infants who are at high risk of child maltreatment

To determine whether clinicians correctly identify newborn infants who are at high risk of child maltreatment, we examined the outcomes of high-risk and non-high-risk children. Infants who were born at Yale-New Haven Hospital from 1979 to 1981 and who were referred by clinicians during the postpartum period to the hospital's child abuse registry because they were considered at high risk of child abuse or neglect became the high-risk group. For each high-risk infant, a comparison infant was selected and matched according to date of birth, gender, race, and method of payment for the hospitalization. For both groups, the occurrence of maltreatment was ascertained by reviewing the medical records until the child's fourth birthday. Each injury for which medical care was sought was classified into one of seven categories (from definite child abuse to accident) by a pediatrician who was unaware of the child's risk status. Information also was recorded about nonorganic failure to thrive and changes in the child's caretaker. Maltreatment (defined as abuse or neglect) occurred more frequently in the high-risk group than the comparison group (adjusted matched odds ratio = 4.3; 95% confidence interval = 1.41, 6.93; p less than 0.001), as did poor weight gain from a nonorganic cause (matched odds ratio = 7.0; 95% confidence interval = 1.59, 30.79; p less than 0.01) and changes in the child's caretaker (matched odds ratio = 9.0; 95% confidence interval = 3.80; 20.55; p less than 0.001). We conclude that as early as the postpartum period, clinicians can identify some families who are at high risk of maltreatment and other major adverse outcomes resulting from poor parenting.
